Owen made 60% of the shots he attempted during his hockey practice. He made 18 shots. How many shots did Owen attempt during his
Dafna11 [192]

Answer:

11 shots

Step-by-step explanation:

  1. 60% of 18 = 10.8
  2. 10.8 rounded = 11

Why we did this:

  1. Owen made 60% of the shots he made, and he made 18 shots in total. Therefore, we would take 60% of 18.
  2. The answer we get is 10.8, but we can't have a part of a shot. That wouldn't make sense. Therefore, we have to round up to 11 shots.

So therefore, Owen made 11 of 18 shots he attempted.

The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?
stiv31 [10]

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

P = 2(l + w)

The side lengths of a rectangle are all multiplied by 5.

This means that l = 5l, w = 5w. So

P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)

What happens to its perimeter?

The rate is:

\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5

The perimeter is multiplied by 5.
