Mrs Larnell is making a snack packs for a a class picnic. She puts 1/4 pound of apples,1/8 pound of nut mix, and 1/16 pound of chocolate in each of the students packs. There are 24 students in the class.What is the total weight of the snack packs? Is there more than one way to solve this problem?

Answers

Answer=10 1/2 pounds

One pack has 1/4+1/8+1/16 pounds of snacks....

Lets starts off giving our fractions of 1/4, 1/8 and 1/16 a common denominator of 16.

1/4=4/16
1/8=2/16
1/16=1/16

So...

x=4/16+2/16+1/16
x=7/16

So... One pack has 7/16lbs of snacks in it

Multiply 7/16lbs by the total number of students(24)..

7/16*24=10 1/2 pounds
________________________________________________________
another way of solving this problem could be...

1/4*24=6
1/8*24=3
1/16*24=1.5

6+3+1.5=10.5 pounds

In the xy plane, what is the y intercept of the graph of the equation y=2 (x+3)(x+4)?

Answers

The y-intercept is the value of y when the graph intersects the y-axis. Graphs intersect the y-axis when x=0, so we just substitute in x=0 to get:

y=2(0+3)(0+4)

y=2(3)(4)

y=24

Therefore, 24 is our answer.

Mikasi and Julie are determining which size sports drink is the better buy per ounce: a 16-ounce bottle for $1.95 or a 36 ounce bottle for $3.05. Who is correct? Explain.Mikas: 16-oz bottle: 12.2¢ per ounce
36-oz bottle: 8.5¢ per ounce

Julie: 16-oz bottle : 8.2¢ per ounce
36-oz bottle: 11.8¢ per ounce

Answers

The answer is
Mikas: 16-oz bottle: 12.2¢ per ounce
36-oz bottle: 8.5¢ per ounce

To calculate price per ounce, we will use the proportion:
16 ounces : $1.95 = 1 ounce : x
Crossing the products:
x = $1.95 × 1 ounce ÷ 16 ounces
x = $0.122 = 12.2¢
So, 16-oz bottle is 12.2¢ per ounce.

Similarly:
36 ounces : $3.05 = 1 ounce : x
Crossing the products:
x = $3.05 × 1 ounce ÷ 36 ounces
x = 0.085 = 8.5¢
So, 36-oz bottle is 8.5¢ per ounce.

It can be concluded that Mikas was correct.
