Answer:
74 cm squared
Step-by-step explanation:
because each triangle will be 7, and each rectangle will be 20. (7*2)+(3*20)=74
Answer:
yes they do
Step-by-step explanation:
both equal 1/3
8/24 = 1/3
5/15 = 1/3
1/3 = 1/3
Answer:

Explanation:
First, we need to determine the slope of the line. The formula for determining the slope of a line is:
m
=
y
2
−
y
1
x

−
x
1
where
m
is the slope and the x and y terms are for the points:
(
x
1
,
y
1
)
and
(
x
2
,
y
2
)
For this problem the slope is:
m

Now, selecting one of the points we can use the point slope formula to find the equation.
The point slope formula is:
y

Substituting one of our points gives:
y

Step-by-step explanation:
Use the cosine law:
We have:
Substitute:
Answer:
$12,958
Step-by-step explanation:
The total amount of the account, principal plus interest, is given by ...
A = P(1 +rt)
The given information tells us ...
12,122 = P(1 + .08×2) = 1.16P
Then the principal amount is ...
12,122/1.16 = 10,450
__
When that same amount is invested using a different rate and time period, it becomes ...
A = 10,450(1 + .09×(2 2/3)) = 10,450×1.24 = 12,958
It will amount to $12,958 in 2 years 8 months at 9%.
