4 1/2 = 18/4
3 3/4 = 15/4
15/4 + 18/4 = 8 1/4 or 33/4
33/4 * 1.6/1 = 52.8/4 = 13.2
When assuming 1 mile equals 1.6 kilometers, Suzanne ran 13.2 kilometers in all.
So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.
I hope I helped!
Answer:
The estimate of the proportion of oil tankers that had spills is 0.25.
Step-by-step explanation:
Proportion of oil tankers that had spills:
1036 tankers.
777 did not have spills.
So 1036 - 777 = 259 had spills.
The proportion is:
The estimate of the proportion of oil tankers that had spills is 0.25.
