The answer is 7.85
First, you divide the diameter by two to get the radius (2.5) and then you multiply by pi(3.14) to get 7.85
Answer:
$15 < $4n + $5
Step-by-step explanation:
We know that Billy needs to make more than $15 between his allowance and the lawns that he mows. This means our inequality should include $15<. Also, since Billy will make $4 per lawn, that means we need to multiply $4 by the number of lawns he needs to mow, n: $4n. So far we have the following: $15<$4n. Next, we know that he makes $5 each week, on top of what he makes mowing each law. This means we need to add the $5 to the $4n. When we put all of these pieces together, we will get the following inequality: $15<$4n+$5
Answer:
17
Step-by-step explanation:
The closer the magnitude of r is to 1, the stronger the correlation.
r=-0.861 indicates stronger correlation than r=0.811 because |-0.861| > |0.811|.
Answer:
<h2>the sides are not equal</h2><h2 />
Step-by-step explanation:
7x + 4 - 2x = 6(x + 1) - x expand
7x + 4 - 2x = 6x + 6 - x combine similar terms
7x - 6x - 2x + x = 6 - 4
