Answer:

It's 24 packs of cat food

Step-by-step explanation:

You have to think of it as 30% of 80.

30 ?

----- = ----

100 80

Now you have to find out what is in the blank by doing 80 times 30 to find what that equals. That equals 2,400. Now you have to find what times a 100 gets you 2,400. You divide a 100 by 2,400 to get 24. There's your answer

Answer:

She had 24 packs left.

Step-by-step explanation:

The equation would be 24 * 30%. Since 30% is equal to 0.30, then we can write the equation as 24 * 0.30, which would equal 24!

How many gallons of a 60% antifreeze solution must be mixed with 70 gallons of 20% antifreeze to get a misture that is 50% antif

Komok [63]

Answer:

<h2>210 gaL 60 % Antifreeze II</h2>

Step-by-step explanation:

In the problem, there are two types of antifreeze

antifreeze I and

antifreeze II

antifreeeze I 20 ----70 gal

Antifreeze II 60 ----- x gal

Total 50 ---------------- (70 + x ) gal

20*70+60*x=50(70+x)

1400+60x=3500+50x

60x-50x=3500-1400

10x=2100

x= 210

x=210 gaL 60 % Antifreeze II

Match each equivalent expression with the property that it represents.

OlgaM077 [116]

Answer:

Associative Property of Multiplication

[ 3(5) (4) = (3) 5(4)]

Identity Property of Multiplication

5(1) = 5

Identity Property of Addition

(3 + 5) + 0 = (3+5)

Commutative Property of Addition

3 + 5 = 5 + 3

Associative Property of Addition

3 + (5 + 7) = (3 + 5) + 7

Step-by-step explanation:

The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.

The identity property of 1 says that any number multiplied by 1 keeps its identity.

Jeff and his family are driving to visit his grandmother.they have driven about 30 miles, which is about 2/3 of the way. ow much

finlep [7]

Say you have 3 cakes. How many cakes would you have eaten if you ate 1/3 of the three cakes? One, you have eaten one cake, out of the three you have.

How many cakes do you have left if you eat 2/3 of the three cakes? Two, you have eaten 2 cakes, and have 1 cake left.

It is a similar approach here, except the confusing part is working "forward", when you really have to work "backward". If you have driven 30 miles, and you have driven 2 parts out of the trip when there is 3 parts of the trip, how many miles have you driven? Hint: Dividing 30 by 2 gives you what fraction of the distance to Jeff's grandmother?

A recycling plant processes an average of 1/3 ton of glass each minute. At approximately what rate does the recycling plant proc

ludmilkaskok [199]

The recycling plant processes 480 tons of glass per day.

Step-by-step explanation:

Quantity of glass recycled each minute = $\frac{1}{3}\ tons$

We know that;

1 hour = 60 minutes

Therefore;

Quantity of glass recycled in one hour = $\frac{1}{3}*60=20\ tons$

1 day = 24 hours

Quantity of glass recycled in 24 hours = 24*20 = 480 tons

The recycling plant processes 480 tons of glass per day.
