Answer:
9.75ft
Step-by-step explanation:
Step one:
Given data
Dimension of the cylinder
Diameter= 6.5 ft
Height= 12.5 ft
You measure the level of milk to be 2.75 ft from the brim
Required
The dept of the milk in the cylinder
Step two:
to get the depth, we need to subtract the measured level from the brim from the height of the cylinder
= 12.5-2.75
=9.75 ft
Hence the Depth of the milk is 9.75ft
Answer:
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the speed of the wind in miles per hour
y ----> the speed of the jet in still air in miles per hour
we know that
<em>With a tailwind</em>

----> equation A
<em>With a headwind</em>

----> equation B
solve the system of equations A and B by elimination
Adds equation A and equation B

<em>Find the value of x</em>



therefore
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
Answer: Option A

Step-by-step explanation:
If we have 5 cans of ketchup they cost $ 5.25. Then the unit price of cans is what each can costs individually.
The unit price should then be less than $ 5.25, and that is the price for 5 cans and we want to know the price for just one can of ketchup.
Then to calculate the price of each can divide the price of the 5 cans by 5.
