Okay. The prices are definitely not the same. At the Snack Shop, granola bars cost $1.25 and granola bars cost $1.30 at Sports Field. By looking at the tenths place, you can tell that 1.25 < 1.30, because 2 is less than 3. So the Snack Shop sells granola bars at a lower price. The answer is C: Snack Shop.

Sarah started 3 miles below the rim of the canyon and hiked until she was 8 miles above the rim. Her brother Sam said she hiked

larisa86 [58]

Answer:

Step-by-step explanation:

We can assume that the rim of the canyon is 0. Sarah started 3 miles <u>below</u>, so -3, BUT distance can never be negative, so it's considered 3 miles. Then, she went 8 miles <u>above</u> zero. So the 3 miles she went <em>before</em> reaching the rim plus the 8 miles she went <em>after</em> reaching the rim equals 11 miles.

So now we know that Sarah is right, but how do we know which equation is correct? Well, if we look at option C:

$|-3+8|=11$

When solving absolute value, we solve everything within the absolute value before applying the absolute value. This means that we add -3+8 first, which equals 5, and then apply absolute value, which still equals 5. This equation is not correct.

I hope this helps!

The mean age and median age of 6 people in a room is 40 years. a person whose age is 60 years leaves the room. question 1. if po

FromTheMoon [43]

Mean = (total of contributors) / (number of contributors)

For the 6 people in the room, you have
40 = (total of contributors) / 6
(total of contributors) = 6*40 = 240

A 60-year-old left the room, decreasing the total of contributors by 60.
(new total of contributors) = (total of contributors) - 60
(new total of contributors) = 240 - 60 = 180

Then the new mean is
(new mean) = (new total of contributors) / (new number of contributors)
(new mean) = 180 / 6 = 36

The mean age of the remaining 5 people is 36.

Consider the exponential functions below.

klio [65]

The functions in order from least to greatest according to their average rates of change are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]

<h3>How to order the functions?</h3>

The rate of change is calculated using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

For function g at the interval [2,3], we have:

$m = \frac{g(3) - g(2)}{3- 2}$

This gives

$m = \frac{20 - 4}{3- 2}$

$m =16$

For function h at the interval [0,2], we have:

$m = \frac{h(2) - h(0)}{2- 0}$

Where:

h(2) = 3(3)^2 - 9 = 18

h(0) = 3(3)^0 - 9 = -6

This gives

$m = \frac{18 + 6}{2 - 0}$

$m = 12$

For function f at the interval [1,2], we have:

$m = \frac{f(2) - f(1)}{2- 1}$

This gives

$m = \frac{12 - 6}{2 - 1}$

$m = 6$

Hence, the functions are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]

I need help with this

Kruka [31]

Answer:

X=9/4

Step-by-step explanation:

-3x+10=5x-8

Subtract 10 from each sides

-3x=5x-18

Subtract 5x from both sides

-8x=-18

Divide both sides by -8

x=9/4
