Answer:
20 in
Step-by-step explanation:
Tree 1:
Rate of growth = (½ ft/2 yr)
12 yr growth = 12 × (½/2)
= 6/2
= 3 ft
= 36 in
Tree 2:
Rate of growth = (4 in/3yr)
12 yr growth = 12 × (4/3)
= 48/3
= 16 in
Difference:
Tree 1 - Tree 2 = 36 - 16
= 20 in
The trees will differ in height by 20 in.
The answer is 2.5 cm
First, you multiply 4 and 12, and you get 48
Then you take 120 and you divide it by 48.
This leaves you with 2.5
To check you multiply 2.5, 4, and 12
Answer: N= 135, M=45.
Step-by-step explanation:The formula to find the degree inside of a shape is: (n-2)180. This is an octagon, so it has 8 sides, plug this in for n.
8-2 * 180
1080 divide by 8 to get the value of n
n=135
The formula for an angle outside of the shape is:
360/n n is still eight, so plug this in for n
360/8
m=45
Answer:
the slope is 
Step-by-step explanation:
Notice that you are given two points to use for the slope calculation:
So we use the formula for the slope of a line given two points:
Answer:
Number of coupons sent to Existing members = 33
Step-by-step explanation:
Number of coupons sent out = 231
Let :
6 times as many to potential members = 6 * X = 6X
while existing members = X
therefore 6X + X = 231
7X = 231
therefore X = 231 / 7 = 33
so existing members = 33
while potential members = 6 * 33 = 198
