How many servings are in 12 cups of rice a.

     One serving is 3/4 cups of rice. To find out how many serving there are in 12 cups of rice, you divide 12 by 3/4. (When dividing fractions, don't ask why. Flip the second one over and multiply).
   12/(3/4) = 12 *(4/3) = 48/3 = 16
     There are 16 servings of rices in 12 cups.

Student Council is selling candy grams. They are using the formula
Luden [163]

Answer:

Our equation is:

y = f(x) = 2.5*x

The domain is the set of the values of x.

The range is the set of the values of y.

They must sell between 55 and 60 candy grams to meet their goal.

If we assume these as restrictions for the domain, then the minimum value of x is 55, and the maximum value of x is 60.

Then the domain is:

D: 55 ≤ x ≤ 60.

Now that we know the domain, we can find the range.

As our equation is linear with a positive coefficient, the minimum in the range will coincide with the minimum in the domain, then we have:

y = 2.5*55 = 137.5

And the maximum will coincide with the maximum in the domain:

y = 2.5*60 = 150.

Then the range is:

y = 137.5 ≤ y ≤ 150

Need HELP!!! For all, I’m truly confused
Nataliya [291]

Answer:

Step-by-step explanation:

The figures dont have enough letters to explain step by step all the exercises.

Bread 1:

The horizontal lines are parallels so both angles must be the same

2x + 21 = 4x - 17

21 + 17 = 4x - 2x

38 = 2x

x = 19

Bread 2:

Angles sum 180°

3y - 5 + 2y - 25 = 180

5y - 30 = 180

5y = 180 +30

5y = 210

y = 42

Bread 3:

Angle ABC is the same as the other 2, since x = 19

ABC = 2x + 21

ABC = 2 * 19 + 21

ABC = 59

Bread 4:

Angle ABC is the same as 3y - 5, y = 42

ABC = 3y - 5

ABC = 3 * 42 -5

ABC = 121

Bread 5:

Angles must be the same

5x - 14 = 2x + 13

5x - 2x = 13 + 14

3x = 27

x = 9

Bread 6:

Angle ABC = 5x - 14 , x = 9

ABC = 5 * 9 - 14

ABC = 31

If you need to understand why the angles must be the same just comment and I will give you more details

If the volume of the pyramid shown is 360 inches cubed, what is its height?
GenaCL600 [577]
<h3>Answer: 9 inches (choice D)</h3>

Work Shown:

V = volume of pyramid

V = (1/3)*(area of base)*(height)

V = (1/3)*(12*10)*h

V = (1/3)*120h

V = 40h

Set this equal to the given pyramid volume 360 cubic inches and solve for h

40h = 360

h = 360/40

h = 9

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What
Kitty [74]

We are given : Cost of a gallon of milk = $2.50.

Cost of a cup of yogurt = $1.20.

Total money Monica has = $20.

Number of cups of yogurt Monica can buy = x.

And inequality made is also correct

1.20x + 2.5 ≤ 20.

Now, we need to solve it for x.

Subtracting 2.5 from both sides, we get

1.20x + 2.5 -2.5 ≤ 20 - 2.5.

1.20x ≤ 17.5

Dividing both sides by 1.20, we get

1.20x/1.20 ≤ 17.5/1.20.

x ≤ 14.5833...

Because it's less than 15, so final answer is : 14 is  greatest number of cups of yogurt Monica can buy.
