Answer:
h = 1000 / (3.14)(r²)
Step-by-step explanation:
Given in the question,
volume of cylinder = 1000 inches³
Formula to use
V = πr²h
where V = volume
π = 3.14
r = radius
h = height
1000 = (3.14)(r²)(h)
h = 1000 / (3.14)(r²)
Answer:
234 divided by 2 is 117, he had 117 when he saved up mowing lawns
Step-by-step explanation:
Answer: The answer is (22, 15).
Step-by-step explanation: Given that 'x' represents the number of cars Leonard has and 'y' represents the number of cars Liam has.
Then, according to the given information, we have

Multiplying the first equation by 2 and adding to the second equation, we have

So,

Therefore, Leonard has 22 cars and Liam has 15 cars.
Thus, (22, 15) is the solution to the given system.
Answer:
multiply 4 and 8 to get 32
Step-by-step explanation:
After substituting, the expression is ...
4·8 +9/7
The order of operations tells you to do multiplication and division before addition and subtraction. You do them left-to-right. The multiplication on the left is 4·8, so you do that first. The result is ...
32 + 9/7
Now, you can do the division:
32 + (1 2/7)
And, finally, the addition:
33 2/7
___
Or, you could skip the division and go straight to adding a whole number and a fraction:
(32·7 +9)/7 = (224+9)/7 = 233/7
What you do is you do 93 x 81.
93
x 81
------------
93
+ 7440
-------------
7,533
That's the square footage. Hope it helps!
