Number 13 please. I know the answer is 20 I just don’t know how to get there

Rudiy27

4/20 is 0.20, which is equivalent to 20%.

Remember that 1.0=100%, 0.5=50%, 0.2=20%, 0.05=5%, and so on.

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more then 20 rows. What are t

grin007 [14]

Answer:

The answer is 2, 5, 7, 10, and 14.

Step-by-step explanation:

Let x be the number of rows. There is not room for more than 20 rows:

x ≤ 20

Since all rows must be equal, when we divide 70 by x, we must get a whole number. So, we must find all divisors of 70 smaller or equal to 20 and they are: 2, 5, 7, 10, and 14.

So, the possibilities are:

2 rows with 35 chairs in each row

5 rows with 14 chairs in each row

7 rows with 10 chairs in each row

10 rows with 7 chairs in each row

14 rows with 5 chairs in each row

Hope this helps!!

Bingel [31]

Answer:

$t = \cfrac{1}{2}$

Step-by-step explanation:

Given equation:

$4(t+\cfrac{1}{4})=3$

Divide both sides by 4:

$t+\cfrac{1}{4}=\cfrac{3}{4}$

Subtract 1/4 from both sides:

$t = \cfrac{3}{4}- \cfrac{1}{4}$

$t = \cfrac{2}{4}$

Simplify:

$t = \cfrac{1}{2}$
