How do you do this problem?
faust18 [17]

The volume of the original cylinder is

... V = π·r²·h

For r=1 and h=1, this is

... V = π·1²·1 = π

For the new cylinder, the volume is 1.089 times that amount.

... V = 1.089π = π·1.1²·(1-k)

... 1.089/1.21 = 1-k

... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%

The appropriate choice is (B) 10.

Without multiplying, tell whether the product 0.644 x 0.25 will be greater than 1 or less than 1? Explain how you know.
stepladder [879]

Answer:

Less than 1

Step-by-step explanation:

As 0.644 and 0.25 are less than 1, then

0.644=\frac{1}{p}

0.25=\frac{1}{q}

where p and q are greater than 1

then

0.644\times0.24=\frac{1}{p.q}

But p.q is greater than 1, so 1/(p.q) is smaller than 1

(12 ÷ 3 + 6) -4 Math help
LekaFEV [45]

Answer:

Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.

<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>

12/3=4

(4+6)-4

<em>Now solve what remains in the parentheses.</em>

4+6=10

10-4

<em>Finally, subtract 4 from 10 and get your answer:</em>

6
