A local gym had 490 members last quarter. This quarter, with a change in its rates, it has 686 members. What is the percent of i

sergij07 [2.7K]

Given:

Number of gym members in last quarter = 490

Number of gym members in this quarter = 686

To find:

The percent of increase in the number of members.

Solution:

We have,

Number of gym members in last quarter = 490

Number of gym members in this quarter = 686

Now, the percent of increase in the number of members.

$\%\text{ of increase}=\dfrac{{Members in this month - Members in last month}}{\text{Members in last month}}\times 100$

$\%\text{ of increase}=\dfrac{686-490}{490}\times 100$

$\%\text{ of increase}=\dfrac{196}{490}\times 100$

$\%\text{ of increase}=\dfrac{2}{5}\times 100$

$\%\text{ of increase}=2\times 20$

$\%\text{ of increase}=40$

Therefore, the gym members increased by 40%.

How do you figure out the reciprocal of a numer? E.g 5, 2/7 and 1&2/5 ??

eimsori [14]

You need to multiply 1 and 5 plus 2.
and for 5 2/7 it would be 5 times 7 plus 2.

So...
5 2/7= 37/7

1 2/5= 7/5

Elaine has 1 gallon of paint. She is going to pour it into a paint tray that measures 10 in wide 12 in long and 5 cm deep. ( 1 g

padilas [110]

Answer:

b. The paint will not fill the tray by 5.22 in3.

Step-by-step explanation:

The computation is shown below:

First we have to determine the volume of tray by using the following equation

$V = L \times W \times H$

Now transform this from dimensions to inches

Now putting the values,

$V = 10\times12\times (5\times(\frac{1}{2.54})) \\\\As\ 5 cm = 5 \times (\frac{1}{2.54})$

the volume would be equivalent to the

236.22 inches^3

Now 1 gallon is 231 inches^3

So, the remaining would be

= 236.22 - 231

= 5.22^3

Therefore the correct option is b.

Hence, all the other options are wrong
