Answer:

1. She could use 7 hours and 11 dollars per hour.

2. $77 (7x11)

3 I'd say my estimate is a little more than the exact amount because I did 6.75 (6.75 because 45 minutes is 75% of a hour) x 10.90 and got 73.575.

Answer:

Step-by-step explanation:

If we're going by estimation, then you can do 11 and 7 hours, meaning that she would make 77 for the 7 hours but the exact answer would be a bit less than the estimation

10.9 times 6.75 is 73.58 roughly. so 3 dollars and 42 cents off

xenn [34]

Answer:

First number = 4

Second number = 9

Step-by-step explanation:

If the first number = x, the second number = x + 5.

The calculation can be expressed as follows:

x + 2(x + 5) = 22

First, expand the bracket 2(x + 5):

x + 2x + 10 = 22

Combine like terms:

3x + 10 = 22

Subtract 10 from both sides:

3x = 12

Divide both sides by 3:

x = 4

First number = 4

Second number = 4 + 5 = 9

A sequence of numbers begins with 12 and progresses geometrically. Each number is the previous number divided by 2.
Leviafan [203]
The common ratio is the current number divided by the previous. So the ratio is 1/2

The sequence is 12, 6, 3, 3/2, 3/4 ...

You can obtain any number multiplying the previous number times 1/2.

6 = 12 *(1/2)

3 = 6*(1/2)

3/2 = 3*(1/2)

If r(x)=2-x^2 and w(x)=x-2, what is the range of (w*r)(x)
horrorfan [7]
First, find the product (w*r)(x):  (w*r)(x) = (x-2)*[2-x^2] = 2x - x^3 - 4 + 2x^2

This is a cubing function.  Since the sign of the cube-of-x term is negative, the graph will begin in Quadrant II and pass through Quadrant IV.  There are no limits on y.  Thus, the range is (-infinity, +infinity).
