Assuming the triangle is an equilateral triangle, each side is equal to 42/3 = 14 millimetres long. Increasing the sides by 50 percent makes each side 14 x (1 + 50/100) = 14 x 1.5 = 21 millimetres. Therefore, the perimeter of this new triangle will be 21 x 3 = 63 millimetres.
30+4+2=36
There's no question there. Something is missing. But your math book probably explains how to solve this anyway.
You need to define your terms better. Percentage of what? Maybe give us the context and we can rephrase and answer your question. If you mean percentage of a liter, then simply multiply the percent by 10.
Perimeter of a square = 4 sides Answer: 1 side = 25% of the Perimeter
20mL
The answer is 22,22 %.
"...increased by four percent" is a fragment because it lacks a subject. WHAT increased by four percent?
0.15 milliliters.
Sixty percent of 5 milliliters is 3 mm.
66 increased by 88 percent = 124.1
95 increased by 90 percent = 180.5
22,500 increased by 4 percent = 23,400
