noreen made 8 2/3 cups of snack mix for a party. her guest ate 3/4 of the mix. how much snack mix did her guest eat?

Answers

Answer:

$6(1)/(2)\text{ cups}$

Step-by-step explanation:

Given,

Total snake mix for the party = $8(2)/(3)$ cups = $(26)/(3)$ cups,

Also, the part of total mix eaten by the guest = $(3)/(4)$

Thus, the total mix eaten by them = part of mix eaten by them × total mix

= $(3)/(4)* (26)/(3)$

$=(26)/(4)$

$=6(2)/(4)$

$=6(1)/(2)\text{ cups}$

noreen made 8 and 2/3 cups which after solving becomes 8.666
now the guest ate 3/4 which means 3/4 of 8.66 which is 6.50 which means the guest ate 6 1/2 cups

Jill earns $15 per hour babysitting plus a transportation fee of $5 per job. Write a formula for E, Jill's earnings per babysitting job, in terms of h, the number of hours for a job. Then solve your formula for h.

Answers

Jill earns $15 per hour babysitting plus a transportation fee of $5 per job. Write a formula for E, Jill's earnings per babysitting job, in terms of h, the number of hours for a job

E is the Jill's earnings

h is the number of hours for a job

$15 is the constant rate per hour so we use linear equation

y= mx+b, Instead of x and y we use h and E

E = mh + b

m is the slope (constant rate $15)

b is the transportation fee $5

So equation becomes E = 15h + 5

Now we solve for h

E = 15h + 5 (subract 5 on both sides)

E - 5 = 15h (divide by 15 )

$(E - 5)/(15) = h$

We solved for h , $h = (E - 5)/(15)$

since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "x" next to the 15. so you would have 15x and then put a plus 5 to show her transportation fee. so you would have the equation of 15x+5:)

Jordan drove for 6 hours at 55 miles per hour, while Matt drove for 3 hours at 60 miles per hour. If Isaac drove 82 miles longer than Jordan and Matt drove combined, for how many miles did Isaac drive?--------- miles

(Hint: Rate × Time = Distance)

Answers

If you look at the equation, we have to multiply the hour and the mph(miles per hour) together to find how many miles they drove. For Jordan, we would have to multiply 6 times 55 which is 330. Jordan drove 330 miles. For Matt, we have to multiply 3 times 60, which gets us 180. Together, they would have drove 510 miles. If Isaac drove 82 miles longer than Jordan and Matt drove combined, we would get 582 miles. Isaac drove 592 miles.

Answers

12) 8 liters in total. each glass holds 1/5 of a liter. 8 x 5 = 40 glasses.

13) 3bars/4people = 3/4 of a bar.

14) same concept as 13. .5quart/3people = (1/6) of a quart of milk.

15) 3 yards in total. divides it into pieces that are 1/4 yard long. so each 1 yard makes 4 pieces. that means 3 yards makes 12 pieces in total.

12) 5 glasses per liter. 5 * 8= 40 glasses
13)
Friend 1- .75
Friend 2- .75
Friend 3- .75
Friend 4- .75
Total is 3 bars
14) 1 quart equals 4 cups
Caleb- 1 1/3 cup
Friend 1- 1 1/3 cup
Friend 2- 1 1/3 cup
15) 3/ 1-4 = 12 pieces
