Answer:

$\large{ \tt{☄ \: EXPLANATION}} :$

✎ Firstly , Remember these things :

To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : $12\% = \frac{12}{100} = \boxed{ 0.12}$

$\large{ \tt{☥ \: LET'S \: SOLVE}} :$

$\large{1. \: \: 52\% \: \text{of} \: 210 = \frac{52}{100} \times 210 = 0.52 \times 210 = \boxed{109.2} }$

$\large{ 2. \: \: 35\% \: \text{of} \: 500 = \frac{35}{100} \times 500 = 0.35 \times 500 = \boxed{175} }$

$\large{3. \: 28\% \: \text{of} \: 866 = \frac{28}{100} \times 866 = 0.28 \times 366 = \boxed{102.48} }$

$\large{ \tt{✺ \: REPEAT \: DAILY} }:$

I will remain focused on my goals. Even if I have a moment of difficulty , I will not give up. I know Success comes with consistency. I know that I will make it. Things will get better. No problem or challenge will stop me. Everything I deserve is coming my way.

A daycare center charges $300 per month for preschool and $3.50 per hour every hour after preschool. The function c = 300 + 3.50

Tcecarenko [31]

Answer:

The total number of hours the child spent in childcare after preschool was 96.5.

Step-by-step explanation:

The cost of the preschool, in function of the number of hours that the child spent there, is given by the following equation:

$c(h) = 300 + 3.5h$

If the one month charges for one child totaly $637.75, what was the total number of hours the child spent in childcare after preschool?

This is h when c(h) = 637.75. So

$c(h) = 300 + 3.5h$

$637.75 = 300 + 3.5h$

$3.5h = 337.75$

$h = \frac{337.75}{3.5}$

$h = 96.5$

The total number of hours the child spent in childcare after preschool was 96.5.

A ramp has a horizontal distance of 10 feet and a vertical rise of 3 feet. Find the length of the ramp. Round to the nearest ten

Tatiana [17]

Answer:

Step-by-step explanation:

Tye length of the ramp can be gotten using Pythagoras theorem.

Horizontal distance = 10ft.

Vertical distance = 3ft

Length of the ramp² = 10²+3²

Length of the ramp² = 100+9

Length of the ramp² = 109

L² = 109

L =√109

L = 10.44ft

Hence the length of the ramp is 10.4ft to the nearest tenth
