The formula to find the cost c of a square sheet of a glass is c=25s2 where a represents the length of a side in feet. how much will ricardo pay for a square sheet of glass that is 3 feet on each side

Answers

To calculate the cost of Ricardo, we just have to substitute the measurement of the length he wants to the function of the cost given. We do as follows:

c = 25s^2
c = 25(3)^2
c = 225

Therefore, the cost would be 225.

Write 10 5/12 as an equivalent improper fraction.

Answers

To get the improper fraction of 10 5/12, multiply the denominator of the fraction and the number on the left which is 10x12=120.

Then you want to add the numerator 5 to 120 to get 125.

Using the denominator 12, and the numerator 125, there is your answer. 125/12.
Hope it wasn't too confusing..
Hope this helped :)

Answer:

125/12

Step-by-step explanation:

First, let's write 10 as a fraction with denominator 12, which is 10=120/12

then 10 5/12 actually means 10+5/12 and now:

120/12+5/12

=125/12

This is because we can add the numerators up if the denominators are the same.

So there you go! Hoped I helped!

x is a point in the interior of rectangle PTRS. If XP=a, XT=c and XR=b, determine XS. a<b<c. Answer should be in terms of a, b and c

Answers

so you cannot really get the exact measure because they didn't give you any measures, but we can infer that if c>b and a then
maybe SX (d) is more than b and a so

a<b<c or d not sure which
sorry if I didn't help

Find the quotient of 5/31 divided by 15/23. Reduce your answer to the lowest fraction

Answers

The answer for dividing 5/31 by 15/23 is 23/93

What is division of fractions?

The division of fractions means dividing a fraction into further equal parts.

For example, If you have three-fourth of a pizza left, and you divided each slice into 2 parts you would get a total of six slices, but this would represent six-eighths of the total pizza.

Given that, find quotient 5/31 divided by 15/23.

5/31÷15/23

We know that, when we divide two fractions, we do the reciprocal of the second fraction and multiply it by the first fraction,

5/31×23/15

= 23 / 93

Hence, the answer for dividing 5/31 by 15/23 is 23/93
