David’s watch broke. He decides to get it fixed instead of replacing it. The total cost to repair the watch can be represented by 0.07(45h) + 45h, where h represents the number of hours it takes to repair the watch. What part of the expression represents the amount of tax David has to pay? Explain.

Answers

0.07

45h represents how much it costs per hour to get it fixed and how long it takes to get it fixed
0.07(45h) would represent the tax because it is 7% of the cost pretax

Consider the figures shown to answer Part A and Parts B.


Which figures have a volume greater than 600 cubic inches?
Select all that apply.
A. Cylinder #1
B. Cone #1
C. Cylinder #2
D. Cone #2
E. Sphere

Answers

Answers are C and E hope this helps!!

volume of sphere is 4.8 times the volume of cone (1).

A). Options (C) and (E) is correct.

B). 4.8 times

To choose the figure.

What is mensuration?

The act of measuring geometry applied to the computation of lengths, areas, or volumes from given dimensions or angles.

Given that:

Part A

Volume of cylinder (1) = πr²h

                                   = π*(6)²*(5)

                                   = 565.5 cubic inches

Volume of cone (1)=π*r²*h/3

                             =π*6²*5/3

                             = 188.5 cubic inches

Volume of sphere =4π*r²*r/3

                               =4π*6²*6/3

                                = 904.8 cubic inches

Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.

Part (B)

Volume of sphere/Volume of cone (1)=904.8/188.5 =4.8

Therefore, volume of sphere is 4.8 times the volume of cone (1).

Write the equation of the circle with the given information.
Center: (5, -13)
Radius: 11

Answers

Answer:

(x - 5)² + (y + 13)² = 121

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (5, - 13 ) and r = 11 , then

(x - 5)² + (y - (- 13))² = 11² , that is

(x - 5)² + (y + 13)² = 121

The sum of two numbers is 70. One number is ten more than twice the other number. Find the numbers.​

Answers

9514 1404 393

Answer:

  20, 50

Step-by-step explanation:

Let x and y represent the two numbers.

  x + y = 70 . . . . . . their sum is 70

  2x +10 = y . . . . . . one is 10 more than twice the other

Using the second equation to substitute for y in the first equation, we have ...

  x + (2x +10) = 70

  3x = 60 . . . . . . . . . subtract 10

  x = 20 . . . . . . . . . divide by 3

  y = 70 -20 = 50 . . . find the other number

The two numbers are 20 and 50.

Answer:

y = 4;

y = 7;

x = 6

Step-by-step explanation:

Given the rule, y = x/2, find the missing values as shown below:

✔️For the first row, to find y, substitute x = 8 into y = x/2,

y = 8/2

y = 4

✔️For the second row, to find y, substitute x = 14 into y = x/2,

y = 14/2

y = 7

✔️For the third row, to find x, substitute y = 3 into y = x/2,

3 = x/2

3*2 = x

PLEASE ANSWER ASAP: Dianna can carry up to 15lbs in her backpack. Her lunch weighs 1 lb, her gym shoes weigh 2 lbs, and her books weigh 1.5 lbs each. Which inequality shows how many books Dianna can carry in her bag if she has her lunch and gym shoes?

Answers

Answer: A

Step-by-step explanation:

she can carry 1.5 pounds of books plus the extra 3 pounds as long as its less than or equal to 15 lbs

The inequality that shows the number of books that Diana can carry in her bag if she has her lunch and gym shoes is 3 + 1.5x  ≤ 15.

What inequality represents the number of books that Diana can carry?

The first step is to determine the total weight of the items in her bag:

1 + 2 = 3lbs

The second step is to determine the inequality sign to use:

the inequality sign to be used is the less than or equal to sign - ≤

The equation becomes: weight of items in her bag + (weight of one book x total number of books) ≤ weight the bag can carry

3 + 1.5x  ≤ 15

Melanie earns $97.50 in 6 hours. Earl earns $296.00 in 20 hours. Who earns the higher rate per hour? Explain your answer.

Answers

We will divide the earnings with the time needed to work to earn that money .


Melanie : 97.5 ÷6=16.25

Earl: 296 ÷20=14.8


So Melanie earns $16.25 per hour,while Earl earns $14.8 per hour

Since 16.25 >14.8,Melanie earns more per hour

(Hope this helped)
Melanie earners a higher rate per hour because 97.50/6 = 16.25
