irga5000 [103]

Answer and Step-by-step explanation:

$Good~Day!$

$Let's~solve`your~equation!$

We know that:

→ $\frac{4}{5}~mi~and~\frac{1}{20}~mi~per~hour.$

→ $So,~multiply~\frac{4}{5}~by~a~number~that~will~give~your~denominator~(5)~to~20$

→ $5$ × $4~is~20,~multiply~\frac{4}{5}~by~4.$

→ $\frac{16}{20}~miles,~or~16~hours,~since~\frac{1}{20}~mi~is~made~per~hour.$

⇒ $So~16~hours~is~your~answer!$

maksim [4K]

Answer:

Step-by-step explanation:

First we have to find their hourly rate. We do this by dividing their total over 4 hours by 4 to get over just 1 hour.

60 / 4 = 15

Now we divide their total of $210 by their hourly rate of $15 to find how many hours it would take.

210 / 15 = 14

I would take 14 hours to earn $210.

If im right brainliest plz

Hope this helps :)

Find the volume of the compound shape.

arsen [322]

<h3>Volume of the hemisphere:</h3>

$v = \frac{2}{3} \pi {r}^{3}$

$v = \frac{2}{3} \times \pi \times {3}^{3}$

$v = 56.55 \: {cm}^{3}$

<h3>Volume of the cone:</h3>

$v = \frac{1}{3} \pi {r}^{2} h$

$v = \frac{1}{3} \times \pi \times {3}^{2} \times 10$

$v = 94.25 \: {cm}^{3}$

<h3>Total volume:</h3>

$v = 56.55 + 94.25$

$v = 150.80 \: {cm}^{3}$

Therefore, the volume of the compound shape is 150.80 cubic centimeters.
