3q+3 because if the dimes is 3x as many as the quarter and plus 3 then you would multiply the quarters by 3 then add 3 and that would give you the number of dimes

The area of a rectangle is 53.3 in2. If the width is 6.5 in, what is the perimeter of the rectangle?
Nuetrik [128]
You can find the length from
  A = LW
  53.3 in² = L×(6.5 in)
  (53.3 in²)/(6.5 in) = L = 8.2 in

The perimeter is twice the sum of length and width.
  P = 2(L +W)
  P = 2(8.2 in +6.5 in) = 29.4 in

The perimeter of the rectangle is 29.4 inches.

spayn [35]

Answer:

<h3>The answer is 10.42 %</h3>

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

p(\%) =  \frac{25}{240}  \times 100  \\  = 10.41666666...

We have the final answer as

<h3>10.42 %</h3>

Hope this helps you
