Well, to find the circumference of a circle, we can use the formula
C=2

r.
So just plug in 3.5 into the formula.
C=2

3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.

Answer:
6
Step-by-step explanation:
We use rates to solve this so we do 28/4=7.
Using that, we know he can do 7 quizzes in 1 week.
Now 7 times 6= 42 right? so do 1 times 6.
The final answer is 6 weeks.
Hope this helps :)
Answer:
Sam will get £30 while Bethan will get £24.
Step-by-step explanation:
The total ratio shared by Sam and Bethan is 5+4 = 9
1 share ratio is the total amount involved divided by the total ratio
That is, £54/9 = £6
if 1 share ratio is £6,
Sam with 5 share ratio will get £6*5 = £30
while Bethan with ratio 4 wiill get £6*4 = £24
f(x) = 7x - 1
-2 = 7x - 1
-2 + 1 = 7x
-1 = 7x
x = -1/7
0 = 7x - 1
1 = 7x
x = 1/7
4 = 7x - 1
4 + 1 = 7x
5 = 7x
x = 5/7
8 = 7x - 1
8 + 1 = 7x
9 = 7x
x = 9/7
So the domain is
Domain = {-1/7, 1/7, 5/7, 9/7}
If j=23 and j-5 is how old Jeffery's brother is then Jeffrey's brother is 17 years old.
So j=17
