Answer/Step-by-step explanation:

The missing length can be found by applying pythagorean theorem. Thus:

Missing length = √((8x)² - (2x)²)

Missing length = √(64x² - 4x²)

✔️Missing length = √(60x²) = 2x√15

Plug in the value of x which is 3

Missing length = 2*3√15

✔️Length = 6√5

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to
vagabundo [1.1K]

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

a store marks up the wholesale price of a skateboard by 112%. The retail price is $35. What is the wholesale price of the skateb
koban [17]
Answer is $31.25
Step by step
We know mark up is 112%
We know sell price (retail) after markup
We are looking for wholesale (original price)
So 112% of x = $35
1.12x = $35
Divide both sides by 1.12 to isolate x
X= 31.25
