Step-by-step explanation:
A store sells four-packs of permanent markers in assorted colors for $3.19 per pack. All spiral-bound notebooks, whether wide-ruled or college-ruled, sell for $1.20 each. Cleo buys x packs of markers, y wide-ruled notebooks, and z college-ruled notebooks. The store charges a 6% sales tax on Cleo’s total bill. Which expression represents the amount Cleo must pay after taxes?
A.
3.19x + 1.20y + 1.20z + 1.06
B.
3.19x + 1.20yz + 1.06
C.
1.06(3.19x + 1.20yz)
D.
1.06(3.19x + 1.20y + 1.20z)
Answer:
D. 1.06(3.19x + 1.20y + 1.20z)
Step-by-step explanation:
Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.
All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.
The cost of the college ruled notebooks can be represented by 1.20z.
In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.
So, the expression will be 1.06(3.19x + 1.20y + 1.20z)
D is the correct answer
Answer:
Solution :-Let cost of marker packs = $3.19xLet the cost of spiral notebook = $1.20 yCost of college ruled book = $1.20 zExpression :-[tex] \tt \: 1.06(3.19x + 1.20y + 1.20 \: z)[/tex]

Which function passes through the points (2, 3) and (4, 4)?
Answer:
C. y=1/2x+2
Step-by-step explanation:
1. Find the slope using the slope formula.
Slope formula: y2-y1/x2-x1
Let the y-value in the second ordered pair (4,4) be y2, and the 3 in the first ordered pair (2,3) be y1. 4 and 2 from these ordered pairs will be x2 and x1.
Plug these values into the equation and simplify.
4-3/4-2
=1/2
Slope is 1/2
2. Choose one of the ordered pairs and plug those numbers and the slope into the point-slope formula.
Point slope formula: y-y1=m(x-x1). M represents the slope, and the x1 and y1 represent the values of the ordered pair.
Let's use the pair (4,4).
y-4=1/2(x-4)
3. Simplify the equation to convert to y=mx+b format.
Multiply the inside of the parentheses by 1/2.
y-4=1/2x-2
Add 4 to both sides.
y=1/2x+2
3. C is your answer, for it matches what you found in the calculations.

a crane has cable with a breaking starin of 6400k
Answer:
The minimum amount of breaking strain the crane can handle is 6350 kg. (Since it is measured to 2 sig. figs, 6349 kg would round down to 6300 kg, hence the min. is 6350 kg.)
The maximum weight of each crate would be 94 kg. (Since it is measured to the nearest 10 kg, 95 kg would round up to 100 kg, hence the max. is 94 kg.)
Therefore, the greatest number of crates that can be safely lifted would be (6350/94) crates which is 67.5 crates, which rounded down is 67 crates.
All numbers are taken as integers in this answer.
Step-by-step explanation:
Hope this helped!
Answer:
66 crates
Step-by-step explanation:
100/2=50
lower bound of 6400kg = 6350kg
10/2=5
upper bound of 90kg = 95kg
6350kg/95kg=66kg

It costs 3 adults and 4 children $94 to visit the zoo. It costs 4 adults and 4 children $112 to visit the same zoo. Write a system of equations to find the cost of a ticket for an adult and the cost of a ticket for a child.
Answer:
Adult ticket = $18
Children ticket = $10
Step-by-step explanation:
Let x represent the cost of adult tickets
Let y represent the cost of children tickets
3x + 4y = 94.......equation 1
4x + 4y = 112........equation 2
Multiply equation 1 by 4 and equation 2 by 3
12x + 16y = 376
-
12x + 12y = 336
4y = 40
y = 10
Substitute 10 for y in equation 1
3x + 4(10) = 94
3x + 40= 94
3x = 94- 40
3x = 54
x = 54/3
x= 18
Hence the price of adult ticket is $18 and the price of children ticket is $10

========================================================
Work Shown:
Recall that for any triangle, the three angles always add to 180
P+Q+R = 180
(x+13) + (10x+13) + (2x-2) = 180
(x+10x+2x) + (13+13-2) = 180
13x+24 = 180
13x = 180-24
13x = 156
x = 156/13
x = 12
Now that we know x, we can find the angle measures
angle P = x+13 = 12+13 = 25 degreesangle Q = 10x+13 = 10*12+13 = 120+13 = 133 degreesangle R = 2x-2 = 2*12-2 = 24-2 = 22 degreesAs a way to check if we have the right answer or not, we see that,
P+Q+R = 25+133+22 = 180
So the answer is confirmed.

What is interest as it relates to a deposit account?
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to talk about how interest relates to a deposit account
A deposit account is one in which we are expected to put an amount of money for a certain period of time
Now, we are supposed to take out the money after the end of the period
The money we are taking out is generally greater than the money we have put in
The difference between the amount of money we have put in and the amount we are taking out after the end of the stipulated period is what we know as interest
This interest is however based on some parameters
Generally, the longer we have put the money, the greater is the amount of money we will be expected to receive at the end of that time

How much grape juice would you need to make 100 quarts of punch?
Answer:
18 quarts.
1.875 quarts.
100÷3
Step-by-step explanation:
Step 1: How much sparkling water would you need to mix with 9 quarts of grape juice?
sparkling
water grape juice
1.5 3/4
X 9
we know that 9÷0.75 = 12 and 9×12 = 108
Hence we would need 18 quarts of sparkling water.
Step 2 : how much grape juice would you need to mix with 3.75 quarts of sparkling water?
sparkling grape juice
water
1.5 3/4
15/4 1.875
1.875 can also be expressed as 1(7÷8) this ÷2 or (1÷2) we get the answer.
you would need 1(7÷8) quarts of juice.

What is an equation of the line that passes through the point (2,-3) and is perpendicular to the line 2x+5y=10?
Answer:
An equation of the line that passes through the point (2,-3) and is perpendicular to the line is:
[tex]y=\frac{5}{2}x-8[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Given the line
[tex]y=-\frac{2}{5}x+2[/tex]
Here, the slope = m = -2/5
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2/5
perpendicular slope = – 1/m = -1/(-2/5) = 5/2
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope and (x₁, y₁) is the point
substituting the values m = 5/2 and the point (2,-3)
[tex]y-\left(-3\right)=\frac{5}{2}\left(x-2\right)[/tex]
[tex]y+3=\frac{5}{2}\left(x-2\right)[/tex]
subtract 3 from both sides
[tex]y+3-3=\frac{5}{2}\left(x-2\right)-3[/tex]
[tex]y=\frac{5}{2}x-8[/tex]
Therefore, an equation of the line that passes through the point (2,-3) and is perpendicular to the line is:
