Answer:
Step-by-step explanation:
Circumference (Perimeter) of Circle Formula: The circumference of a circle is determined by the following formula
C
=
D
×
π
where
D
is the length of the diameter of the circle and
π
≈
3.14
.
Circumference (Perimeter) of Circle Formula: The circumference of a circle is determined by the following formula
C

π
where
r
is the length of the radius of the circle and

So you first have to change the first part into an improper fractions
So (9/4)*-8 Then you expand and you get (9*-8)/4
Then you get -72/4
The answer is -18
Answer:
The answer is 15.3
Step-by-step explanation:
We are looking for the hypotenuse for this question and this is how I solved it:
A^2 + B^2 = C^2
8^2 + 13^2
64 + 169
= 233
(Rounding the answer to the nearest tenth will get you the answer of 15.3)
C= how many pounds of cashews in a bag
P=how much the cost
Solve for C
we know that P would have to be $18.11
Sub wat P= to in the equation
$18.11=2.59c+1.79(8-c)
Start with multiplying
1.79(8)=14.32(c)=14.32c
Then add like terms
2.59c+14.32c=16.91c
Divide to get C by itself. So that 16.91 cancel itself.
16.91c/16.91c=18.11/16.91
C=1.07
I might be wrong but I tried so wateves
