Answer:
The radius of the tree trunk is 7 inches.
Step-by-step explanation:
circumference = 2(3.14)radius
43.96 = 2(3.14) r
43.96 = 6.28r
7 = r
The Answer is Three.
That's the largest nmber of 3-digit perfect squares that could be on the list.
The list is so;
169 = 13²
196 = 14²
961 = 31²
The thre numbers, 1, 6, and 9 can be rearranged three ways to form three 3-digit perfect squares in 169, 196, and 961. No other arrangement of a 3-digit perfect square can yield more or equal.
Answer:
x = 215
Step-by-step explanation:
15^2-13=x-3
225 - 13 = x - 3
212 + 3 = x - 3 + 3
215 = x
Answer:
c = 40 + 50m
Step-by-step explanation:
40 is a constant, it is not affected by the number of months the person works out at the gym for.
There is a monthly fee of $50. So, every month Colton gets charged $50, so this is the variable.
The total cost would be represented by the equation c = 40 + 50m then.
Let's look at this using a number for m.
If Colton went to the gym for 2 months then we can set up the equation like this:
c = 40 + 50(2)
c = 40 + 100
c = 140
Therefore he spends a total of $140 for 2 months.

We have to find out the number of trees planted per unit rate of time.
Kyla can plant 300 trees in 1 hour, so she can plant 300 trees in 3600 seconds. This implies that she can plant
trees per second.
On the other hand, Mia can plant 1 tree in 13 seconds, so she can plant
trees per second.
Working together they can plant
trees per second, i.e. it takes them 156/25 seconds to plant a tree.
We conclude that they plany 100 trees in
seconds
