Answer:
13.9
Step-by-step explanation:
Use Pythagorean Theorem:
Both of the lengths given are the legs,
13.5^2 + 3.2^2 = c^2
182.25 + 10.24 = c^2
192.49 = c^2
13.87 = c
Answer: A
Step-by-step explanation:
We don't know what the dimensions are, but any numbers that have a sum of 120 will work. Let's use 3, 4, and 10.
3 x 4 = 12 10 x 12 = 120
But if you double each dimension:
6 x 8 = 48 48 x 20 = 960 To find how much the sums changed:
960 / 120 = 8
The new volume is 8 times what it originally was! 960 in.
It will take Kelley 9 hours because 540 miles (distance) divided by 60 mph (rate) will give you 9 hrs
