Mr. Scruggs got some money for his birthday. He spent 1/5 of it on dog treats. Then, he divided the remainder equally among his

Mariulka [41]

Answer:

a. $\frac{4a}{15}$

b. $225

Step-by-step explanation:

Let Mr. Scruggs got money for his birthday be 'a'

He spent $\frac{1}{5}$ of it on dog treats = a × $\frac{1}{5}$

= $\frac{1}{5}a$

remainder amount would be = a - $\frac{1}{5}a$

= $\frac{4a}{5}$

Then he divided the remainder money equally among 3 favorite charities.

$\frac{\frac{4a}{5}}{3}$

= $\frac{4a}{15}$

a. Each charity receive $\frac{4a}{15}$

b. If he donated $60 to each charity.

$\frac{4a}{15}=60$

$a=\frac{15\times 60}{4}$

a = $225

Mr. Scruggs received $225 for his birthday.

Mia paints interior walls at a rate of 12\dfrac{\text{m}^2}{\text{h}}12 h m 2 12, start fraction, m, start superscript, 2, end

Travka [436]

Answer:

$2,000\ \frac{cm^{2}}{min}$

Step-by-step explanation:

The correct question is

Mia paints interior walls at a rate of 12 m^2/h. At what rate does she paint in cm^2/min?

Remember that

$1\ m=100\ cm$

$1\ h=60\ min$

Convert m^2/h to cm^2/min

substitute the values

$12\ \frac{m^{2}}{h}=12\frac{(100)^{2}}{60}=2,000\ \frac{cm^{2}}{min}$
