The final value of a painting after its initial value, m, increases by 2/5
Sindrei [870]

Answer: 7/5m

Step-by-step explanation:

The initial value of the painting = m

Increase in the painting = 2/5

The final value of the painting will be the addition of the initial value of the painting and the increase. This will be:

= m + (2/5 × m)

= m + 2/5m

= 5/5m + 2/5m

= 7/5m

If y varies directly with x. and y=10 when x=5.6, find the value of y when<br> X=3
Nady [450]

Answer: 5.3571

Step-by-step explanation:

The formula used to calculate direct proportion is: y = kx

We will find the constant of proportionality when y=10 and x=5.6. This will be:

y = kx

10 = 5.6k

k = 10/5.6

k = 1.7857143

The value of y when X=3 will be:

y = kx

y = 1.7857143 × 3

y = 5.3571

Marta is solving the equation S = 2Πrh + 2Πr2 for h. What is the result?
yulyashka [42]
<span>S = 2Πrh + 2Πr2
Manipulating the equation for h.
Step 1. subtract </span><span>2Πr2 on both sides.

</span>S - 2Πr2 = 2Πrh + 2Πr2 - 2Πr2
S - 2Πr2 = <span>2Πrh
</span>
Step 2 . divide <span>2Πr on both sides
</span>
(S - 2Πr2)/2Πr = 2Πrh/<span>2Πr

</span><span>h = </span>(S - 2Πr2)/2Πr
