Choose the top right one. Then add them up all together and divide it by 5 (as there’s 5 quizzes). The result will be your mean/average.

One hundred people in a supermarket survey

tiny-mole [99]

Answer:

13%

Step-by-step explanation:

So basically the people who had a pet in the store were: 47, 33, and 7 out of 100. Now we add up the numbers of the people who have pets which in total, is 87, out of 100. But that's not all. Those are the people who have pets to find the people who didn't have pets, we subtract 87 from 100 to get 13, or 13% as our answer.

Evaluate the expression,<br> if x = 9, y = 3, and z = 5.<br> z2 • (x-y)

Bad White [126]

$\huge\text{Hey there!}$

$\mathsf{z^2 \times (x - y)}$

$\mathsf{= 5^2 \times (9 - 3)}$

$\mathsf{= 5 \times 5 \times (9 - 3)}$

$\mathsf{= \bold{25}\times(9 - 3)}$

$\mathsf{= 25\times \bf 6}$

$\mathsf{= \bf 150}$

$\huge\text{Therefore, your answer should be: }$

$\huge\boxed{\frak{150}}\huge\checkmark$

Daisy is going 12 mph and Sally is going 8 mph if they where 60 miles apart how many hours would it take for them to meet up

abruzzese [7]

Answer:

3 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph

d -----> the distance in miles

t ----> the time in hours

x ----> distance traveled by Daisy to the meeting point

60-x ----> distance traveled by Sally to the meeting point

so

$s=\frac{d}{t}$

Solve for d

$d=st$

<em>Distance traveled by Daisy to the meeting point</em>

$d=st$

we have

$d=x\ mi\\s=12\ mph$

substitute

$x=12t$ ----> equation A

<em>Distance traveled by Sally to the meeting point</em>

$d=st$

we have

$d=(60-x)\ mi\\s=8\ mph$

substitute

$60-x=8t$ ----> equation B

substitute equation A in equation B

$60-12t=8t$

solve for t

$12t+8t=60\\20t=60\\t=3\ hours$
