Elizabeth uses 33.75 ounces of granola for 15 servings of trail mix. if each serving contains the same amount of granola, how muchnis in each serving

 2.25 ounce

Step-by-step explanation:

To find the amount of ounces of granola in each serving, we simply use proportion to solve this.

Let x represent ounces of granola in one serving

33.75 ounces  =   15 servings

    x                   =   1 serving

We cross multiply

15 x  =   33.75 ounces × 1  

15 x  =   33.75 ounces

We divide both-side of the equation by 15

  =    

x   =    2.25 ounce      

(on the left hand side 15 on the numerator will divide that of the denominator, on the right hand side, just use your calculator to divide 33.75 by 15)

Therefore, there are 2.25 ounces of granola in each servings.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
