A chemical engineer has tested 56 water samples. These samples make up 25% of the total number of samples that need testing.

1 answer:

4 0

25% can be written as 1/4.

What This tells you, is that 56 is one fourth of the total amounts of samples needing to be tested. Therefore, 56 x 4 is the total amount.

56 x 4 = 224

So 224 is the correct answer.

I hope this Helps!

Step-by-step explanation:

The rectangle has 4 corners of 90 degrees.

Here a rectangle is divided into two right triangles. In right-angled triangles, the opposite side at a 30-degree angle is half a chord...I replace x instead of length.. So x / 2 = 4--->x:8

The perimeter of a rectangle is equal to (length + width) × 2--->(8+4)×2=24m^2
