Mrs. Peele's family went out to dinner. They spent $42.50 on dinner, 7% tax, and on top of both costs they left an 18% tip. How much total did her family pay for dinner?
Answer: $53.13
Step-by-step explanation:
First find how much they spent on tax by multiplying 42.50 by 7%.
7% * 42.50 = 2.98 This means the tax amount was $2.98.
Next find the how much the tip was by multiplying 18% by 42.50.
18% * 42.50 = 7.65 This also means the tip was $7.65.
Now combine the cost of the dinner plus the cost of tax plus the cost of tip to find how much in total they spent.
42.50 + 7.65 + 2.98 = 53.13

a coin is tossed 7 times. what is the probability of getting all heads? express your answer as a simplified fraction or a decimal rounded to four decimal places.
the probability of getting all heads after 7 tosses of a coin is 1/128, expressed as a simplified fraction or a decimal rounded to four decimal places is 0.0078.
When a coin is tossed, the probability of getting either heads or tails is 1/2. This probability remains constant regardless of the number of tosses.
In order to determine the probability of getting all heads after 7 tosses of a coin, we must calculate the probability of getting a head on each toss and multiply the individual probabilities together:
Probability of getting a head on the first toss = 1/2
Probability of getting a head on the second toss = 1/2
Probability of getting a head on the third toss = 1/2
Probability of getting a head on the fourth toss = 1/2
Probability of getting a head on the fifth toss = 1/2
Probability of getting a head on the sixth toss = 1/2
Probability of getting a head on the seventh toss = 1/2
The probability of getting all heads = (1/2) x (1/2) x (1/2) x (1/2) x (1/2) x (1/2) x (1/2) = 1/128
Therefore, the probability of getting all heads after 7 tosses of a coin is 1/128, expressed as a simplified fraction or a decimal rounded to four decimal places is 0.0078.

A square has a side length of 16.5 in. If the area is multiplied by 9, what happens to the side length?
The side length is multiplied by 4.5.
The side length is multiplied by 9.
The side length is tripled.
The side length is doubled.
Answer: The side length is tripled.
Step-by-step explanation: Area is length times width, or in the case of a square, s²
If the area is multiplied by 9, (that is 3²) it means the sides are 3 times as long.
16.5² = 272.25
(3)(16.5) = 49.5
49.5² = 2450.25
the same as 272.25 × 9
Triple the side length results in 9 times the area.
Write the equation of the line, given the y and x-intercepts.
y-intercept = –2, x-intercept = –3
(need help asap so please hurry thank you!!)
Answer:
y = -(2/3)m - 2
Step-by-step explanation:
recall that the general equation of a straight line in slope-intercept form is
y = mx + b
where, m is the slope and b is the y - intercept
here we are given that the y - intercept is -2, hence the equation becomes:
y = mx + (-2)
or
y = mx -2
we are also given that the x-intercept is -3, which means that when y = 0, x = -3 (simply substitute this into our new equation to solve for m)
0 = m(-3) -2
0 = -3m - 2 (add 3m to both sides)
3m = -2 (divide both sides by 3)
m = -(2/3)
hence our equation is now
y = -(2/3)m - 2

The given problem states that a bucket contains 512 gallons of water. Water spills from the bucket so that only 5 pints remain. We need to find out how many pints of water spill from the bucket. The first step towards the solution of the problem is to convert 512 gallons to pints, which is given below;
1 gallon = 8 pints512 gallons = 8 × 512 pints = 4096 pints. Now, we know that 5 pints of water are remaining after the spill. Hence, the total water that has spilled from the bucket would be;4096 - 5 = 4091 pints. Therefore, 4091 pints of water would have spilled from the bucket.
To solve the given problem, we need to convert gallons to pints, which is given below;1 gallon = 8 pints512 gallons = 8 × 512 pints = 4096 pints. Now, we know that only 5 pints of water remain in the bucket. Hence, we need to find out the total amount of water that has spilled from the bucket. To find out the total amount of water spilled, we need to subtract the remaining water from the initial water, which is given below;4096 - 5 = 4091 pints. Therefore, 4091 pints of water would have spilled from the bucket. Hence, t 4091 pints of water.

A gardener has 140 feet of fencing to put around a rectangular vegetable garden. The function A(w)=70w-w^(2) gives the garden's area A (in square feet ) for any width w (in feet ). Does the gardener have enough fencing for the area of the garden to be 1300ft^(2) ?
No, the gardener does not have enough fencing for the area of the garden to be 1300 square feet. The maximum possible area that can be achieved with 140 feet of fencing is given by the function A(w) = 70w - w^2. We need to find the width value (w) that corresponds to an area of 1300 square feet.
To determine if the gardener has enough fencing, we can set up an equation using the given function: 1300 = 70w - w^2. Rearranging this equation, we get w^2 - 70w + 1300 = 0.
By solving this quadratic equation, we find that the roots are w = 25 and w = 45. Since the width value (w) must be positive, we can conclude that the width of the garden cannot be 45 feet. Therefore, the gardener does not have enough fencing to create a garden with an area of 1300 square feet.
In summary, based on the given quadratic equation, the gardener cannot achieve an area of 1300 square feet with the available 140 feet of fencing. The maximum achievable area corresponds to a width of 25 feet.

(a) painted red on only one of their faces?
(b) painted red on two of their faces?
(c) painted red on three of their faces?
(d) without red paint on their faces?
The number of unit cubes in each category is as follows:(a) Cubes painted red on only one face: 24 (b) Cubes painted red on two faces: 20 (c) Cubes painted red on three faces: 8 (d) Cubes without red paint on their faces: 12.
To solve this problem, let's analyze the different types of cubes based on the number of faces painted red.
(a) Cubes painted red on only one face:
On the big cube, there are 6 faces exposed to the outside. Each face consists of a 2x2 grid of unit cubes. Thus, each face has 4 unit cubes painted red.
Since there are 6 faces, the total number of unit cubes painted red on only one face is 6 * 4 = 24.
(b) Cubes painted red on two faces:
On the big cube, the corner unit cubes have two faces exposed to the outside, and each edge unit cube has three faces exposed. There are 8 corner unit cubes and 12 edge unit cubes in total. Therefore, the number of unit cubes painted red on two faces is 8 + 12 = 20.
(c) Cubes painted red on three faces:
On the big cube, there are 8 corner unit cubes, and each of these cubes has three faces exposed to the outside. Therefore, the number of unit cubes painted red on three faces is 8.
(d) Cubes without red paint on their faces:
To determine the number of unit cubes without red paint on their faces, we subtract the sum of the previous three categories from the total number of unit cubes, which is 64.
Number of cubes without red paint = 64 - (24 + 20 + 8) = 12.

what is the final cost of a $42 meal with a 15% tip?
Answer: $48.03
Step-by-step explanation: I think
Answer:
$48.00 + $7.20 = $55.20.
Step-by-step explanation:
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $48 meal cost is.This is always done by multiplying 0.15 by $48.00, or
0.15 x $48.00=$7.20.
So, the amount of tip you are going to leave is $7.20.
This makes the total cost of your meal (to write on your charge slip or other payment)

An ice cream shop has 10 flavors and one can choose 4 different flavors. The question asks for the total number of possible flavor combinations.Therefore, we need to find the number of ways in which 4 flavors can be chosen from 10 flavors.
In such cases where order does not matter and repetitions are not allowed, we can use the formula for combinations which is as follows:C(n, r) = n! / (r! (n - r)!)Where n is the total number of items, r is the number of items being chosen at a time and ! represents the factorial function.
Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors
.Explanation:The formula to be used for this type of question is combination. Combination is the method of selecting objects from a set, typically without replacement (without putting the same item back into the set) and where order does not matter. The formula for combination is given by C(n,r)=n!/(r!(n-r)!).

Answer:
Step-by-step explanation:
First, put -4x+y=7 into y=mx+b format
move -4x to the other side (or add 4x on both sides)
y=4x+7
now, parallel lines have the same slopes, but not the same y intercepts.
So, you already know the slope of your new line
y=4x+b
now we need to find b (y intercept)
take the point (4,-3) and put it into the equation above
-3=4(4)+b
-3=16+b
move 16 to the other side (or subtract 16)

.Billy-Joe and Bob purchased a pool with capacity of 60 gallons for the farm. One day, at 13.00, Billy-Joe placed a horse into the pool, filling it with water at a rate of 3 gal per hour. After ten hours (23.00), horses and cow started drinking the water at a combined rate of 1 gal/hr. Five hours later (4.00), Bob noticed the animals drinking and placed a second hose in the pool which filled it at a rate of 2 gal/hr. At what time could Bob declare the pool was full of water?
Bob could declare the pool was full of water at 6.00.Bob could declare the pool was full of water at 6.00 after Billy-Joe initially filled it and animals drank from it for a certain period.
From 13.00 to 23.00, Billy-Joe filled the pool with water at a rate of 3 gallons per hour for 10 hours, resulting in 3 gallons/hour * 10 hours = 30 gallons of water in the pool.
From 23.00 to 4.00, the combined drinking rate of the horses and the cow was 1 gallon per hour. Therefore, during this period, the water level decreased by 1 gallon/hour * 5 hours = 5 gallons.
At 4.00, Bob placed a second hose in the pool, which filled it at a rate of 2 gallons per hour.
Now let's calculate the remaining capacity of the pool after 4.00:
The initial capacity of the pool was 60 gallons.
From 13.00 to 23.00, 30 gallons were filled.
From 23.00 to 4.00, 5 gallons were consumed.
So, the remaining capacity is 60 gallons - 30 gallons - 5 gallons = 25 gallons.
With the second hose filling the pool at a rate of 2 gallons per hour, it would take 25 gallons / 2 gallons/hour = 12.5 hours to fill the remaining capacity.
Adding the time it took to reach 4.00, the total time needed to fill the pool would be 12.5 hours + 5 hours = 17.5 hours.
Therefore, Bob could declare the pool was full of water at 4.00 + 17.5 hours = 21.5 hours after 13.00, which is equal to 6.00.
Bob could declare the pool was full of water at 6.00 after Billy-Joe initially filled it and animals drank from it for a certain period.

A school volleyball team consists of 7 male and 8 female players. Only 12 of the players are to be selected to attend the tournament in Vancouver next weekend. Determine the probability to the nearest hundredth that equal numbers of males and females are selected to go to Vancouver.
The probability, to the nearest hundredth, that equal numbers of males and females are selected to go to Vancouver is approximately 0.43.
To determine the probability that equal numbers of males and females are selected to go to Vancouver, we need to calculate the number of ways to select 6 males and 6 females from the total pool of 7 males and 8 females.
The number of ways to select 6 males out of 7 is given by the combination formula:
C(7, 6) = 7! / (6!(7-6)!) = 7
Similarly, the number of ways to select 6 females out of 8 is:
C(8, 6) = 8! / (6!(8-6)!) = 28
Since we need to select equal numbers of males and females, we multiply the number of ways to select males and females together:
Total number of favorable outcomes = C(7, 6) * C(8, 6) = 7 * 28 = 196
Now, we need to calculate the total number of ways to select any 12 players from the total pool of 15 (7 males + 8 females):
Total number of possible outcomes = C(15, 12) = 15! / (12!(15-12)!) = 455
Finally, we can calculate the probability of selecting equal numbers of males and females by dividing the number of favorable outcomes by the total number of possible outcomes:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes) = 196 / 455 ≈ 0.431
Therefore, the probability, to the nearest hundredth, that equal numbers of males and females are selected to go to Vancouver is approximately 0.43.
