The bag was filled with red marbles and blue marbles in the ratio of 5:7. If there were 180 marbles in the bag,how many were red?

I really need help and fast

Please help me with b & c!

A piece of driftwood floats on the surface of the ocean. Due to the wave motion, its height rises and falls relative to the height of the water with no waves. The maximum height of the driftwood is 2 ft, relative to the surface, and its minimum height is −1.5 feet. A storm surge causes the height of the waves to be multiplied by 4.What is the minimum height of the driftwood in the storm? __________ ft.What is the distance between the maximum and minimum heights of the driftwood during the storm? ______________ ft.

If I understand you, a person eats about 14 pounds of turkey a year. So we will divide all that turkey (1120 pounds) by 14 to find out how many years.

1,120 ÷ 14 = 80**So it will take 80 years.** (Since babies can't eat that much turkey a year it will actually take more than 80 years - or the person can eat more than 14 pounds in some years to make up for their early years when they ate less) I know it's a math question, but I also like to be realistic about it. Who measures the amount of turkey they eat yearly anyway? :-)

1,120 ÷ 14 = 80

convert the hours to improper fractions

2 and 1/3 hours=2+1/3=6/3+1/3=7/3

5 and 1/4=5+1/4=20/4+1/4=21/4

ratio and proprtion

time/pay=(7/3)/18.2

if work 21/4 hours how much is pay

(7/3)/18.2=(21/4)/pay

times both sides by 18.2pay aka cross multiply

(7/3)pay=(21/4)18.2

(7/3)pay=382.2/4

times both sides by (3/7) to clear fraction (7/3 times 3/7=21/21=1)

pay=1146.6/28

pay=40.95

will earn $40.95 in 5 and 1/4 hours

2 and 1/3 hours=2+1/3=6/3+1/3=7/3

5 and 1/4=5+1/4=20/4+1/4=21/4

ratio and proprtion

time/pay=(7/3)/18.2

if work 21/4 hours how much is pay

(7/3)/18.2=(21/4)/pay

times both sides by 18.2pay aka cross multiply

(7/3)pay=(21/4)18.2

(7/3)pay=382.2/4

times both sides by (3/7) to clear fraction (7/3 times 3/7=21/21=1)

pay=1146.6/28

pay=40.95

will earn $40.95 in 5 and 1/4 hours

you're answer is C because you can do the F.O.I.L. and then multiply it by 4. like this:

4(x+3)(x-3)

4(x^2+3x-3x-9)

**Answer:**

First picture: 60

Second picture:

**Step-by-step explanation:**

The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)

(3*4*1/2)=6

Then, we multiply the above equation by the Height. Which makes the equation become 60.

The first step for the second picture is the same. We first find the area of the triangle on top.

(12*9*1/2)=54

Then we multiply the height by our above answer.

(54*20)=1,080

The other measurements that were there aren't needed. So, next time, completely ignore them!

Hope you have a good day/night! Good luck!

THE FIRST IS 135

THE SECOND TRIANGLE IS 20

THE SECOND TRIANGLE IS 20

A business rents in-line skates and bicycles.

During one day the business has a total of 26 rentals and;

Collects $485 for the rentals.

In-line skates are rented for $10 per day and;

Bicycles are rented for $35 per day.

__Solution:__

Let the number of in-line skates rented be x and;

The number of bicycles rented be y.

x + y = 26 ... (i)

10x + 35y = 485 ... (ii)

This forms a system of linear equations (i) and (ii)

Solving this system by elimination;

We multiply (i) by 10 and (ii) by 1

10x + 10y = 260 ... (i)

10x +35y = 485 ... (ii)

Subtracting (ii) - (i) gives;

25y = 225 , y = 225/25 = 9

x = 26 - 9 = 17

The number of in-line skates rented were 17.

The number of bicycles rented were 9.

**Step-by-step explanation:**

For this problem, we can simply plug in the coordinate point into the given formula.

(-8, 6) = (-8 + 5, 6 - 4)

(-8, 6) = (-3, 2)

So, A' is at point (-3, 2)

Now, we have to find the distance from A to A'. We can use the distance formula.

So, the distance between A and A' is about 6.4 units.
