Use the Pythagorean Theorem to confirm the three sides of a right triangle.
3. a = 5, b = 12,c = 13
4. a = 4, b = 10,0 = 20
Answer:
3) confirmed right triangle
4) not a right triangle
Step-by-step explanation:
3) 5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169
4) 4^2 + 10^2 = 20^2
16 + 100 = 400
116 does not equal 400

Answer:
y = 25x + 128.8
Step-by-step explanation:
y = total cost
x = amount of days the car was rented
25 represents the daily charge for the fee and the insurance (15+10=25)
128.8 represent the cost for miles driven by Jerry
This was calculated by multiplying the amount of miles he drove (644) by the cost of each mile (.20)
644x.20=128.8 so the cost for miles driven is $128.8 which is why it was added to the equation
Gavin drank 3/4 of a liter of orange juice from the container, which was 3/8 of the orange juice that was originally in the container. How much orange juice was originally in the container?
Answer:
Originally there were 2 liters.
Step-by-step explanation:
--
3/8 of the orange juice = 3/4 liter
1/8 of the orange juice = 3/4 ÷ 3
1/8 of the orange juice = 3/4 x 1/3
1/8 of the orange juice = 1/4 liter
Find 8/8, which is one whole.
1/8 of the orange juice = 1/4 liter
8/8 of the orange juice = 1/4 x 8
8/8 of the orange juice = 2 liters
There were originally 2 liters of orange juice in the container
