It's hard to read your image, unfortunately.  Seems to me that it states that C=50.2 and that the formula for circumference is C=2pi*r.
   
                                                                    50.2
In that case, C= 50.2 = 2(3.14)r, and  r = ------------- = 7.99.  
                                                                    6.28

We are to round this to one decimal place.  That results in r = 8.0.

Corey gets paid $6 per hour to work at a snack stand. This weekend , he worked on both Saturday and Sunday. he made total of $48
Dahasolnce [82]

Answer:

5 hours

Step-by-step explanation:

1. Find out how many dollars he earned on Saturday

3 x 6 = 18

He earned 18 dollars on Saturday.

2. Subtract 18 from 48 since that is from Saturday, not Sunday

48 - 18 = 30

3. Divide 30 by 6 to see how many hours he worked on Sunday

30/6 = 5

Can someone help me? And possibley tell me how to solve this as well? I'm totally clueless haha
Bumek [7]

Answer:

? = 3

Step-by-step explanation:

To find the value of ?, substitute one of the ordered pairs from the table [except (0, 0)] into the given formula and solve for ?.

Given formula:

\sf y=\boxed{?} \:x

Substitute x = 1 and y = 3 into the formula:

\sf 3=\boxed{?} \:1

To isolate ? divide both sides by 1:

\implies \sf \dfrac{3}{1}=\dfrac{\boxed{?} \:1}{1}

\implies \sf 3=\boxed{?}

Therefore, ? = 3:

\implies \sf y=3x

Check by inputting another value of x from the table into the found formula and comparing the calculated y-value:

\sf x=-2 \implies y=3(-2)=-6 \quad \boxed{\sf correct}

\sf x=3 \implies y=3(3)=9 \quad \boxed{\sf correct}
