Jamie was asked to make r the subject of the formula

aksik [14]

Answer:

Assuming the formula below, the answer is:

$r=\dfrac{12s}{12+t}$

Explanation:

I can teach you how to make r the subject of a formula, with an example.

Other similar question asks to make r the subject of this formula:

$t=\dfrac{12(s-r)}{r}$

1. Apply multiplication property of the equalities: muliply both sides of the equality by r

$t\times r=12(s-r)$

2. Apply distributive property on the right side

$t\cdot r=12s-12r$

3. Addition property: ad 12r to both sides

$t\cdot r+12r=12s$

4. Common factor r on the left side

$r(12+t)=12s$

5. Division property of equalities: divide both sides by 12 + t

$r=\dfrac{12s}{12+t}$

Between 11 P.M. and 8:45 A.M., the water level in a swimming pool decreased by 3/8 in. Assuming that the water level decreased a

jeka94

Answer:

the water level drop per hour is $\frac{1}{26}\,\,\frac{in}{h} \approx 0.03846\,\,\frac{in}{h}$

Step-by-step explanation:

Notice that in between 11 PM and 8:45 AM on the following day, there is a change in time equal to 9 hours and 45 minutes = 9.75 hours.

If the water level of the pool dropped by 3/8 of an inch, and the rate was constant, then the rate of level drop per hour is:

$\frac{\frac{3}{8} in}{9.75\,h} =\frac{1}{26}\,\,\frac{in}{h} = 0.03846\,\,\frac{in}{h}$
