5v-4/10=4/5 How do i solve for the variable v

2 answers:

7 0

5v - $\frac{4}{10}$ = $\frac{4}{5}$ Multiply both sides by 10
50v - 4 = $\frac{40}{5}$ Divide the fraction
50v - 4 = 8 Add 4 to both sides
50v = 12 Divide both sides by 50
v = $\frac{12}{50}$ SImplify the fraction
v = $\frac{6}{25}$

5v= 4/5 + 4/10
5v= 8/10 + 4/10
5v= 12/10
5v= 6/5
V= 6/25

A furniture designer builds a trapezoidal desk with a semicircular cutout. What is the area of the desk?

nirvana33 [79]

Answer:

$Area = 26478cm^2$

Step-by-step explanation:

Given

See attachment for desk

Required

The area

First, calculate the area of the semicircular cutout

$Area = \frac{\pi r^2}{2}$

Where

$r = 60cm$

So:

$A_1 = \frac{3.14 * 60^2}{2}$

$A_1 = \frac{11304}{2}$

$A_1 = 5652cm^2$

Next, the area of the complete trapezium

$Area= \frac{1}{2}(a + b) * h$

Where

$a = 300$

$b = 2 * r = 2 * 60 = 120$

$h = 153$

So:

$A_2 = \frac{1}{2} * (300 + 120) * 153$

$A_2 = \frac{1}{2} * 420 * 153$

$A_2 = 32130cm^2$

The area of the desk is:

$Area = A_2 - A_1$

$Area = 32130cm^2 - 5652cm^2$

$Area = 26478cm^2$

Erickson Inc. is considering a capital budgeting project that has an expected return of 25% and a standard deviation of 30%.

KonstantinChe [14]

Answer:

a. 1.20

Step-by-step explanation:

Given that Erickson Inc. is considering a capital budgeting project that has an expected return of 25% and a standard deviation of 30%.

i.e. given that

$\mu = 25%\\\sigma = 30%$

Coefficient of variation = $\frac{\sigma}{\bar x}$

substituting the values we get

Coefficient of variation = $\frac{30}{25} \\=1.20$

Out of the four options given we find only one option a is the correct answer.
