natali 33 [55]

Answer:

$333.33

Step-by-step explanation:

This question is a little bit confusing, but I am assuming you mean to say that the 72% of the total pay, which is the amount he took home, is $240. So, then you can set up a proportion to solve the problem.


72\frac{72}{100} = \frac{240}{x}

Then, you multiply the proportion out, getting 72x = 240*100

multiply the right side out and then divide by 72 to get $333.33

The points in the table lie on a line. Find the slope of the line.
Wewaii [24]

Answer:

Slope (m) = -\frac{3}{4}

Step-by-step explanation:

Using any two pairs from the table of values given, (-2, 5) and (2, 2):

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Where,

(-2, 5) = (x_1, y_1)

(2, 2) = (x_2, y_2)

Plug in the value into the slope formula:

Slope (m) = \frac{2 - 5}{2 -(-2)}

Slope (m) = -\frac{3}{4}

Lm=6x+3 mn=4x-17 ln=x+14 (find the range of possible values for x, help a sister out)
katen-ka-za [31]

Answer:

Step-by-step explanation:

lm=6x+3

mn=4x-17

ln=x+14

lm+mn>ln

6x+3+4x-17>x+14

10x-14>x+14

9x>28

x>28/9

mn+ln>lm

4x-17+x+14>6x+3

5x-3>6x+3

-x>6

x<-6

lm+ln>mn

6x+3+x+14>4x-17

7x+17>4x-17

3x>-34

x>-34/3

combining x<-6 or x>28/9

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin. Write the ratio of hours spent prac
Pavel [41]

Given:

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin.

To find:

The ratio of hours spent practicing violin to hours spent playing softball three different ways.

Solution:

We have,

Time spend on Softball = 5 hours

Time spend on Violin = 4 hours

The ratio to hours spent practicing violin to hours spent playing softball is

\text{Required ratio}=\dfrac{\text{Time spend on Violin}}{\text{Time spend on Softball}}

\text{Required ratio}=\dfrac{4}{5}

It can be written as

\text{Required ratio}=4:5

\text{Required ratio}=4\text{ to }5

Therefore, the ratio of hours spent practicing violin to hours spent playing softball three different ways are \dfrac{4}{5}, 4:5 and 4 to 5.
