It would cost $105 because if you do 13+13+13= 39
22+22+22= 66
66+39= 105.

Roman55 [17]

Answer:

88,306

Step-by-step explanation:

Multiplying times 7 steps:

Step 1. 8 x 7 = 56

Step 2. 1 x 7 = 7

Step 3. Add the 5 from step 1. 7 + 5 = 12

Step 4. 3 x 7 = 21

Step 5. Add the 1 from step 3. 21 + 1 = 22

Step 6. 1 x 7 = 7

Step 7. Add the 2 from step 5. 7 + 2 = 9

Equals = 9226

Steps for times 6:

Step 1. 6 x 8 = 48

Step 2. 1 x 6 = 6

Step 3. Add the 4 from step 3. 6 + 4 = 10

Step 4. 3 x 6 = 18

Step 5. Add the 1 from step 3. 18 + 1 = 19

Step 6. 1 x 6 = 6

Step 7. Add the 1 from step 5.

Equals = 79080

Now add the two 9226 + 79080 = 88, 306

Took me a while to work out and explain lol.

Write the ratio of the area of a circle with radius r to the circumference of the same circle

Goshia [24]

Answer:

$\frac{r}{2\pi r} =\frac{1}{2\pi }$

Step-by-step explanation:

A ratio is a comparison of two quantities and can be written in several forms including fractions. It is most commonly written in fraction form or a:b.

To write a ratio, we count the number of each quantity we are comparing or use the variable for that quantity. We write radius:circumference. Recall, the circumference of a circle can be found using $\pi d$ or $2\pi r$ .
