7% of 120 (Need work shown)

Answers

Answer 1
Answer: 1% of 120 is 1.2, so 7 *1.2 = 8.4

Also you could set up the proportion 7/100 = x/120 and solve for x.
Answer 2
Answer:

120=100%

x= 7 %

cross-multiply

100x= 120*7

100x= 840

x= 840/100

x= 42/5

x= 8.4

Therefore 7% of 120 is 8.4


I hope that's help !

The marching band ordered 19 pizzas for a party. Each pizza had 6 slices. Felipe are 7 of the slices. How many were left for the rest of the band?

Answers

Answer:

107

Step-by-step explanation:

multiply 19 times 6 minus 7 because Felipe ate 7

Final answer:

The marching band has 107 pizza slices left after Felipe ate 7 slices from a total of 114 slices obtained from 19 pizzas.

Explanation:

This math problem requires to determine the number of pizza slices left after Felipe ate some. To start, we multiply the total number of pizzas (19) by the number of slices each pizza has (6). This gives us a total of 114 slices. Felipe ate 7 slices. Subtracting these from the total, we get 107 slices left for the rest of the band.

My sub was doing other things and not helpful and now I have homework I don't know how to do -5x+3y=19
-5x+7y=11

Answers

-5x+3y=19
-5x+7y=11

Here, we use substitution to solve for both variables. 

Solve for y first 

-5x + 3y = 19
+5x           +5x

3y = 19 + 5x 
y = 19/5 + 5/3x

Now plug that into the other equation.   -5x+7(19/5 + 5/3x) =11

-5x + 26.6 + 35/3x = 11
-5x + 35/3x = 20/3x

20/3x + 26.6 = 11
           -26.6    -26.6

11 - 26.6 = -15.6

20/3x = -15.6

x = -119.6

Ahhh, now time to solve for y

-5x+3y=19
-5(-119.6) + 3y = 19
598 + 3y = 19
-598            -598

19 - 598 = -579

3y = -579
y = - 193

WE ARE DONE!!!

Answer: y = -193 and x = -119.6

A flight attendant has a hand cart in the shape of a rectangular prism that is filled with boxed snacks. The hand cart has a volume of 70/3ft cubed. Each snack box is in the shape of a cube with an edge length of 1/3 ft. How many snack boxes could fit in the hand cart?

Answers

The correct answer for the question that is being presented above is this one: "630 snack boxes."

The volume of the container box is 70/3 ft^3.
The dimension of the small cube is 1/3 ft. So we need to get the volume of the small box.
Volume = (1/3)^3 = 1/27 ft^3

In order to get the number of snack boxes,
=  (70/3) / (1/27)
= (70/3) * (27)
= 70 * 9
= 630 snack boxes.
