Answer:
r equals StartFraction C Over 2 pi EndFraction
Step-by-step explanation:
we know that
The circumference of a circle is equal to

where
r is the radius of the circle
Solve for r
That means -----> isolate the variable r
Divide by 2π both sides

Simplify right side

Rewrite

so
r equals StartFraction C Over 2 pi EndFraction
Answer: $3.42
Step-by-step explanation:
Interest= Principal x Rate x Time
From the question, Principal =$2,150
Rate= 22.9% annually means per year, to calculate the monthly rate, we divide by 12
=22.9%/12 = 1.908% per month
Time = one month, meaning one month out of 12months = 1/12
I is therefore: 2150 x 1.908% x 1/12
= 2150 × 0.01908 x 0.0833
=$3.42
I hope this is clear, please mark as brainliest answer.
They are either the same, or opposite number.
Answer:
Step-by-step explanation:
On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.
After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.
Therefore we can write the following equation: (Where d = number of days)
B = 10 + 8d
W = 0 + 9d = 9d
We are told that eventually they will sell the same amount which means
B = W
This means we can say,
10 + 8d = 9d
If we subtract 8d from both sides we get
10 = d
Therefore it will take 10 days for them to sell the same amount of cookie dough.
