Answer:

8 hours

Step-by-step explanation:

Create an equation that sets the costs equal to each other, where h is the number of hours

3.5h + 20 = 4.75h + 10

Solve for h

3.5h + 20 = 4.75h + 10

20 = 1.25h + 10

10 = 1.25h

8 = h

So, it will take 8 hours for the costs to be equal

Answer:

Integers are numbers that include the negatives, zero and positives.

Step-by-step explanation:

If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!

First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.

Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.

Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.

Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.

I hope this strategy helped and if it didn't here's that circle chart!!

I really hope this did help tho!!

Answer:

40.82

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

C = 2πr

81.64 = 2(3.14)r - divide both sides by 2

40.82 = 3.14r - divide both side by 3.14

13 = r

Answer:

650

Step-by-step explanation:

[tex]7/10s = 455\\7s = 4550\\s = 650[/tex]

Answer:

650

Step-by-step explanation:

[tex]\frac{70}{100} =\frac{455}{y}[/tex]

First, to answer this you cross multiply. This means:

[tex]45,500=70y[/tex]

Now you divide each side by 70, and you get 650

Answer:

a₇₅ = - 430

Step-by-step explanation:

There is a common difference between consecutive terms, that is

d = 81 - 88 = 74 - 81 = 67 - 74 = 60 - 67 = - 7

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 88 and d = - 7 , then

a₇₅ = 88 + ( 74 × - 7) = 88 - 518 = - 430

The 75th term of the arithmetic progression is -430

What is Arithmetic Progression?

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is

Tn = a + (n - 1) d, where Tₙ = nth term and a = first term.

Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP : Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the Arithmetic progression be = 88 , 81 , 74 , 67 , 60 ...

The first term of the AP is a ₁= 88

Now , the common difference of the AP d = second term - first term

                                                                      = 81 - 88

                                                                      = -7

Now , the nth term of the arithmetic progression is given by ,

Tn = a + (n - 1) d

Substituting the values in the equation , we get

T₇₅ = 88 + ( 75 - 1 ) ( -7 )

     = 88 + 74 ( -7 )

     = 88 - 518

     = -430

Therefore , the value of T₇₅  is  -430

Hence , The 75th term of the arithmetic progression is -430

The answer is 87

For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4

the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up

Hope this helps :)

Answer:

A=40

Step-by-step explanation:

There are two sides of a rectangle that are the length.

So at 3 twice.

3+3=6

Subtract it from 26.

26-6=20

Divide by 4

20/4=5

Width= 5

Add 3 to 5

3+5=8

L=8

Check:

5+8+5+8=26

10+16=26

26=26

Area= L*W

8x5=40

A=40

Hope I'm correct!

Answer:

216 in³

Step-by-step explanation:

The volume of a rectangular prism is length x width x height

A cube is a special rectangular prism in which all the edges are the same length (like a square)

To find the volume of a cube given the height 6 just solve 6·6·6=216

Don't forget your units and since you cubed 6 inches, they are now in³ or inches cubed

Answer:

36 sq inches

Step-by-step explanation:

bases are the two parallel sides -- 8" and 4"

height is perpendicular to the base -- 6"

formula for area of a trapezoid:  A = 1/2h·(sum of bases)

A = 1/2(6)(8 + 4)

A = 3(12)

A = 36 sq inches

Step-by-step explanation:

You can look at the graph and answer it

Answer:

Horizontal lines have no vertical change -- it continues straight left or right. In other words, the change in the y values between any points on the graph is 0, since there is no change. This means that the slope of a horizontal line is 0

Step-by-step explanation:

hope this helps

Answer:

0

Step-by-step explanation:

The line's slope remains constant throughout, its a line that passes through the y - axis therefore it's slope will be 0.

Answer:

x = 23

Step-by-step explanation:

These are supplementary angles so the sum of those angles add up to 180:

3x + 16 + 5x - 20 = 180

8x - 4 = 180

8x = 180 + 4

8x = 184

x = 184/8

x = 23

Answer: 25%

Step-by-step explanation:

3/4x=5700

x = 7600

7600 - 5700 = 1900

19/76 = 25/100 which is 25%
