It is the change in y for a unit change in x along the line.

Answer:

24%

Step-by-step explanation:

Answer:

24%

Step-by-step explanation:

t = ???

P = 2,200

I = 528

r = 12%

528 = 2,200(t x 1)

t = 528/2,200

t = 0.24

t = 0.24 x 100 = 24%

You're welcome.

Answer:

They must have lost 19 games.

Step-by-step explanation:

If you plug in 53 into the equation, you get 53 = 3w + 11. You subtract 11 from both sides, resulting in 42 = 3w. You divide 3 from both sides this time, resulting in 14 = w. Since W is the number of wins, and you're trying to figure out games lost, you subtract 14 from the number of games played, so 33-14 is equal to 19.

Multiplying a negative number by a negative number will give you a positive product.

When multiplying two negative integers, it comes out as positive.

For example, we are given the equation -4 * -4.

Using the rule [ -(-a) = a ], the answer for the equation is 16.

Best of Luck!

Answer:

Taylor read 146 pages during these three days.

Step-by-step explanation:

32 pages on Monday.

On Tuesday twice, as much as Monday. So 2*32 = 64 on Tuesday.

On Wednesday, 14 less pages than Tuesday. 64 - 14 = 50. So he read 50 pages on Wednesday.

How many total pages did Taylor read during these three days?

32 + 64 + 50 = 146

Taylor read 146 pages during these three days.

Answer:

8t+3>569

Step-by-step explanation:

i think this is right

Answer:

8t-3 ≥ 569.

Step-by-step explanation:

'T' represents the number of hours.

'-3' represents the amount paid for equipment fees.

When solved, we get:

8t ≥ 572

t ≥ 71.5 hours.

Answer: x = 1

Step-by-step explanation: When we have this kind of setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side

by subtracting 2x from both sides of the equation.

That gives us 3x + 9 = 12.

Now we can move our numbers to the right by

subtracting 9 from both sides and we get 3x = 3.

Now divide both sides by 3 and x = 1.

Answer:

Step-by-step explanation:

in a 7 day week, he would need $24.50

No, $20 is not enough to buy lunch for a week.

Comparing numbers in maths, defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given that, A student has an allowance of $20 a week. He wants to buy lunch at school for $3.50 every day.

Since, there is off on Sundays in a school, so we will consider 6 days in week.

3.50x6 = 21

That means he need $21 to buy lunch for the week

21>20

Hence, $20 is not enough to buy lunch for a week.

Answer:

the volume of the pipe is 649.98 cubic inches.

Step-by-step explanation:

We have been given that a collar of Styrofoam is made to insulate a pipe. We are asked to find the volume of the given pipe.

We will use volume of hollow cylinder formula to solve our given problem.

[tex]\text{Volume of hollow cylinder}=\pi R^2h-\pi r^2h[/tex]

where,

R = Radius of external cylinder,

r = Radius of internal cylinder.

h = Height of cylinder.

substituting our given values in above formula, we will get:

[tex]\text{Volume of hollow cylinder}=\pi (5\text{ in})^2(\text{23 in})-\pi (4\text{ in})^2(\text{23 in})\text{Volume of hollow cylinder}=\text{23 in}\cdot 3.14 ((5\text{ in})^2-(4\text{ in})^2)\text{Volume of hollow cylinder}=\text{23 in}\cdot 3.14 (25\text{ in}^2-16\text{ in}^2)\text{Volume of hollow cylinder}=\text{23 in}\cdot 3.14 (9\text{ in}^2)\text{Volume of hollow cylinder}=649.98\text{ in}^3[/tex]

Therefore, the volume of the pipe is 649.98 cubic inches.

Answer:

Step-by-step explanation:

0 is whole number and 1 is natural number they both end in infinity. So there is only 0 in whole number but not in natural number.thats why every natural number is whole number

Natural numbers are the counting

numbers and they are always positive.

The set of natural numbers begin at 1 and go on indefinitely.

The natural numbers look like {1, 2, 3, 4, 5, ...}.

When we include 0 in the set of natural numbers, the new set,

{0, 1, 2, 3, 4, ...} is called the set of whole numbers.

Notice that all natural numbers are

included within the set of whole numbers.

We can represent the relationship between these

two sets of numbers using a diagram.

The bigger circle below represents the set of whole numbers

and all natural numbers will appear within the set of whole numbers.

In summary, natural numbers are the same as whole numbers except for the fact that whole numbers include 0.

Answer: 110, 35, 70, G, J, F, E, B, A, H, C, D, I

Step-by-step explanation:

8. For number 8, you will be using the exterior angle theorem. The exterior angle theorem states that the exterior angle equals the two angles inside the given triangle. Since we have 50 and 60, you will add 50 + 60 to get 110.

9. In this problem, you shall use the vertical angle theorem. The vertical angle theorem is simply that any angles vertical from one another are congruent. So a will be also 35 degrees.

10. This is an image depicting two lines cut by a transversal, creating multiple congruent angles. With this, you will be using the alternate interior angle theorem. Alternate interior angles are angles on different sides of the transversal but inside both of the lines that were cut into, as shown above. So,  b will also equal 70 degrees.

Answer:

4/663

Step-by-step explanation:

1/13 = probability of ace (as 1st card)

4/51 = probability of jack (as 2nd card) -->

4/663

The probability that the first card is an Ace and the second card is a Jack without replacement will be 0.00603318 or 4/663.

The probability of an event occurring is defined by probability.

Probability is also known as chance because, if you flip a coin, the likelihood that it will land on its head or tail is nothing more than the chance that either the head or the tail will occur.

In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.

Without replacement will be dependent events.

Probability of dependent events

P(A and B) = P(A) × P(B/A).

Probability of the first card as  Ace = 4/52 ( 4 are Aces out of 52 cards)

Probability of the second card as jack = 4/51 ( since 1 ace has been removed)

P( Ace and Jack ) =  4/52 ×  4/51 = 4/663 = 0.00603318

Hence the probability that the first card is an Ace and the second card is a Jack will be 0.00603318.

Answer:

x= 20

Step-by-step explanation:

a flat angle is, in terms of geometry, the space between an intersection between two lines whose opening measures 180 degrees or 180º. Since the angle is 180º there is no difference between two lines or a line and we can say that the angles in a straight line always add up to 180º.

Step 1

define

according to the graph

3x+80+2x=flat angle=180°

3x+80+2x=180°

Step 2

solve for x

3x+80+2x=180°

5x+80=180

subtract 80 in each side

5x+80-80=180-80

5x=100

divide by 5

(5x)/5=100/5

x=20

Answer:

392 units^3

Step-by-step explanation:

What you are using is a "net." The net of a solid figure is formed when a solid figure is unfolded along its edges and its faces are laid out in a pattern in two dimensions.  Nets of rectangular prisms are made up of rectangles and squares

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism.

For this problem, it would be the area of one triangle times two (since there are two) and the area of a rectangle times 3 (since there are three rectangles). Let's start with the triangles...

Triangles

The formula for area of a triangle is 1/2bh. The base is 8 and the height is 4, so 8*4 = 32/2 = 16. Now 16 *2 = 32, meaning that the combined areas of the triangles is now 32.

Let's try rectangles...

Rectangles

The formula for area of a rectangle is simply bh. Base is 8, height is 15, meaning the product is 120. Multiply by 3 and you get 360. The combined areas of the rectangles is now 360.

Now add the two values for the surface area:

360 + 32 = S.A. = 392 units^3
