Answer:
Mary=34
Bill=38
Step-by-step explanation:
bill's number=b
mary's number=m
(m+b)/2=36
b=m+4
(m+m+4)/2=36
(2m+4)/2=36
m+2=36
m=34
b=34+4=38
Answer:
b. 1.69
Step-by-step explanation:
So to solve this problem we need to simply find the percentage increase from 11.8 to 12 =>
to solve this we would do 12 - 11.8 = 0.2 --> 0.2 is our "difference in the increase" -->
now we divide this by our amt. which is 11.8 --> 0.2/11.8 = approx. 0.0169
--> finally multiply that by 100 which is simply moving the decimal places 2 places right giving us the final answer of 1.69

The answer to your question is d
Hey there!
To start, this is an exponential, meaning your equation should be in this format:
y=a(1±b)^x where a is the principal amount, b is the rate, and x is the years passed. If b is a decrease rate, you would subtract it from one, and if it is an increase rate, you would add it to 1. In this case, the rate 5.5% is a decrease rate so you would perform 1-5.5% or 1-0.055 which would be 0.945.
Now, plug in your known values:
y=3900(0.945)^15
Finally, simplify to get:
y=1669.33
Now, round to the nearest whole number (you can't have a decimal of a tree) to get 1669 trees after 15 years.
Answer:
<A
Step-by-step explanation:
The vertex must in the middle to name the angle
EAU or UAE
Since there is only one angle attached to the vertex, we can name it with just the vertex
A
