Answer:

207.24 inches

Hope this helps

Step-by-step explanation:

first you need to find the circumference...

2pi R (r=radius=11)

2 x 3.14 x 11 = 69.08         (i'm using 3.14 as pi so yea...)

3 rotations...

69.08 x 3= 207.24 inches

What is the slope of the line that contains the points (-1, 2) and (4, 3)? A. 5 B. 1/5 C. -1/5 D. -5
LuckyWell [14K]

Answer:

1/5

Step-by-step explanation:

We can find the slope of a line using two points by

m = (y2-y1)/ (x2-x1)

    = (3-2)/(4 - -1)

    (3-2) /( 4+1)

Quick help please! I can't figure out the answer, I got this same question wrong 2 times in a row.. Any help is appreciated!

It has one X-intercept. Graph it on Desmos and you can see the line, and then it becomes obvious it is one x-intercept.

assuming you meant to simplify above,

Answer:

Relative frequencies

First row

0.8125 ,0.1875 ,16

Second row

0.555 ,0.444 ,9

third row

18 , 7 ,  25

Step-by-step explanation:

Given data

               allowance        No allowance          total

Chores         13                   3                          16

<u>No chores      5                   4                           9</u>

<u>Total              18                   7                            25</u>

<u><em>Relative frequencies</em></u>

               allowance          No allowance                  total

Chores         \frac{13}{16} = 0.8125     \frac{3}{16} = 0.1875                       16

No chores      \frac{5}{9} = 0.555      \frac{4}{9} = 0.444                            9

Total  <u>            18                   7                                   25</u>

the ratio of boys to girls at the beach cleanup was 7:8. If there were 43 boys, how many girls were there?
faltersainse [42]
I'm pretty sure there were 48 girls at the beach clean up. 43 ÷ 7 = 6.14 (6 cause there's not gonna be floating males with missing body parts). So we multiply 6 x 8 and we get 48.
