Answer:

=11/4 cm

Step-by-step explanation:

We are finding the perimeter

P = 2(l+w)

l = 3/4 cm

w = 5/8 cm

The common denominator is 8

l = 3/4 *2/2 = 6/8

P = 2(6/8+5/8)

=2(11/8)

=22/8

=11/4 cm (2 1/4 cm)

It says an integer or a fraction, not a mixed number

How many liters each of a 25% acid solution and a 50% acid solution must be used to produce 80 liters of a 40% acid solution?

alina1380 [7]

Answer:

32 and 48 liters

Step-by-step explanation:

Let 25% solution is x liters, then 50% solution is (80 - x) liters.

<u>Acid content is going to be same:</u>

0.25x + 0.5(80 - x) = 80*0.4
0.25x - 0.5x + 40 = 32
0.25x = 8
x = 8/0.25
x = 32 liters

So 32 liters of 25% solution and 80 - 32 = 48 liters of 50% solution

hannah is making maffins. The recipe calls for 5/8 cup of milk to make 20 muffins. What is the unit rate for cups of milk per mu

STALIN [3.7K]

Answer:

32 muffins

Step-by-step explanation:

one cup of milk will make 32 muffins

you can set up a proportion of milk/muffins = milk/muffins

let 'x' = number of muffins made from one cup of milk

5/8 ÷ 20 = 1 ÷ x

cross-multiply to get 5x = 20(8)

5x = 160

x = 32

What is the answer because am stuck

Anarel [89]

Answer:

30 Oranges!

Step-by-step explanation:

Given that for every 2 apples there are 3 oranges.

How many oranges would be there in a basket of 20 apples?

Since for every couple of apples we have 3 oranges we will calculate how many couples of apples are there in the basket.

Given there are 20 apples. This means that there are $\frac{20}{2}$ = 10 pairs of apples.

Since for one pair we have three oranges, for 10 pairs we would have 3 X 10 = 30 oranges.

Therefore, we can conclude that the number of oranges in the bigger basket would be 30.
