Use the rulers to help you estimate the perimeter of this triangle.
6.5 in. 3 in. 6 in. 7 in.

6 inches

Step-by-step explanation:

The perimeter of a triangle is a + b + c

Where, a, b, c are the length of the 3 sides of the triangle ;

Using the ruler ;

a = 1.5

b = 2

c = 2.5

Therefore,

a + b + c

1.5 + 2 + 2.5

= 6 in

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
