There are 233 feet of wood that are required, but we can only buy in lengths of 11 feet. Therefore, we have to take the ceiling of the division 233/11 because if you take less than what you need, you won't have enough, but if you take more than you need, but only the bare minimum of it, you will have enough without wasting money. Therefore, 233/11 = 21, but you have that extra couple feet left, so you need to buy an extra plank to get 22 planks of wood.
"As shown" ? You have a picture to work with but you're not sharing it ?
Fortunately, the question includes all the information that's needed to answer it,
so I don't need to see the picture.
The volume of a cylinder is (pi) x (radius)² x (height) .
Radius = 1/2 of the diameter = 15 mm
Volume = (pi) x (15 mm)² x (30 mm) = 6,750 pi mm³ = 21,205.75 mm³ .
That's a correct answer, but the number is slightly awkward and inconvenient. Let's
change it to a bigger unit, so the number will be smaller and easier to carry around.
Remember that 10 mm = 1 cm
So (10 mm)³ = 1,000 mm³ = 1 cm³
and 21,205.75 mm³ = 21.20575 cm³
Answer:
It will take 10 hours.
Step-by-step explanation:
We know distance = rate * time
Sally's rate = 55
Jim's rate = 65
We want Jim to be 100 miles ahead of Sally
The time will always be the same.
d =Sally's distance
Sally
d = 55t
Jim
d+100 = 65 t
We know have 2 equations with 2 unknowns. Substitute d= 55t into Jim's equations
55t + 100 = 65t
Subtract 55t from both sides.
55t-55t + 100 = 65t-55t
100 = 10t
divide each side by 10
100/10 = 10t/10
10 = t
Answer:
They are 15 prime numbers between 1 and 50
