Answer:
How do you calculate after tax rate of return?
After-tax return on investment is the net return to the investor after ordinary income and capital gains taxes are subtracted. This is calculated as: After-tax return on investment = ((P1 - Po) (1 - Tc) / Po) + C1(1 - To) / Po.
How do you calculate before tax return?
The pre-tax rate of return is calculated as the after-tax rate of return divided by one, minus the tax rate. For example, suppose a person obtains a 4.25% reporting rate for ABC shares and is subject to a 15% income tax. Therefore, the pre-tax rate of return is 5% or 4.25%/(1 - 15%).
How do you calculate real rate of return after tax and inflation?
To calculate the real rate of return after tax, divide 1 plus the after-tax return by 1 plus the inflation rate. Dividing by inflation reflects the fact a dollar in hand today is worth more than a dollar in hand tomorrow. In other words, future dollars have less purchasing power than today's dollars.

Complete Question:
A rectangular prism has a length of 7 m, a height of 5 m, and a volume of 140 m³. What is the width? A prism has a length of 7 meters, width of w, and height of 5 meters.
Which steps are correct? Check all that apply.
a) Substitute the known values into the formula: 140 = 7(w)(5).
b) Substitute the known values into the formula: 7 = 140(w)(5).
c) Substitute the known values into the formula: 5 = 7(w)(140).
d) Solve for the unknown: w = 4 m.
e) Solve for the unknown: w = 7 m.
f) Solve for the unknown: w = 2 m.
Answer:
a) Substitute the known values into the formula: 140 = 7(w)(5).
d) Solve for the unknown: w = 4 m.
Step-by-step explanation:
The steps that are correct are Options a) and d). This is because:
Step 1
The volume of a rectangular prism is calculated as:
Volume of a rectangular prism = Length (l) × Width(w) × Height(h)
The unit of the volume or a rectangular prism is in cubic metres (m³)
In the question, we are asked to find the unknown value which is the width and we were given the following known values:
Length = 7 m,
Height = 5 m
Volume = 140 m³
Step 2
Solve for the unknown value( Width)
Volume of a rectangular prism = Length (L) × Width(W) × Height(H)
140m³ = 7m × Width(m) × 5m
140m³ = 35m² × Width(m)
Width(w) = 140m³ ÷ 35m²
Width(w) = 4m
Hence, the unknown Width(w) = 4m
From the above explanation we can see that the correct steps is Option a) and Option d)
Answer:
Step-by-step explanation:
Volume of rectangular prism= Length x width x height
V=L x W x H
140=7 x W x 5
140= 35 x w
W= 140/35
W= 4

This is the same as saying y^9
===================================================
Explanation:
When we apply the square root to the expression [tex]a^{2b}[/tex], we end up with [tex]a^b[/tex]
[tex]\sqrt{a^{2b}} = a^b[/tex]
The exponent 2b divides in half to get b
Based on that rule, we can then say:

[tex]\huge\mathfrak\colorbox{white}{}[/tex]
Interpretation 2:
[tex] 5^{x}=15[/tex]
Take logarithm to the base 5 on both sides:

The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?
6d5 – 2c3d2 + 5c2d3 – 12cd4 + 8
6d5 – 4c3d2 + 3c2d3 – 4cd4 + 8
6d5 – 4c3d2 + 5c2d3 – 12cd4 + 8
6d5 – 2c3d2 – 3c2d3 – 4cd4 + 8
By subtracting the given addend to the sum, we see that the other addend is:
[tex]6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8[/tex]
How to get the other addend?
We know that the sum of two polynomials is:
[tex]8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9[/tex]
One of the addends is:
[tex]2d^5 - c^3d^2 + 8cd^4 + 1[/tex]
To get the other addend, we can subtract the given addend to the sum:
[tex]8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9 - (2d^5 - c^3d^2 + 8cd^4 + 1)\\\\6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8[/tex]
Then we can conclude that the other addend is:
[tex]6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8[/tex]

Answer:
(-21, 54.5)
Step-by-step explanation:
Hello there!
We have two methods to solve this problem.
Substitution methodElimination method.We will limit ourself to Substitution method.
3x – 2y = -4.................... 1.
4x + 2y = 25................... 2.
First lets manipulate eq.2 in terms of y.
4x + 2y = 25
2y = 25 - 4x
y = 25/2 - 2x .............. eq.3
Substitute eq.3 into eq.1
3x – 2(25/2 -2x) = -4
Solve for x.
Opening the brackets
3x - 25 - 4x = -4
-x = 21
x = -21
Substitute x into equation 3
y = 25/2 - 2x
=> y = 25/2 - 2(-21)
= 54.5
In terms of x and y; (x,y)
= (-21, 54.5)

Eleanor is working her way through school. She works two part-time jobs for a total of 24 hours a week. Job A pays $5.80 per hour, and Job B pays
$7.40 per hour. How many hours did she work at each job the week that she made $158.40.
Step-by-step explanation:
a = hours at job A
b = hours at job B
a + b = 24
a = 24 - b
5.8a + 7.4b = 158.4
note we can use the a = 24 - b identity in the second equation :
5.8×(24 - b) + 7.4b = 158.4
139.2 - 5.8b + 7.4b = 158.4
1.6b = 19.2
b = 12 hours
a = 24 - b = 24 - 12 = 12 hours
she worked 12 hours on job A and 12 hours on job B.

Answer:
C. 80Step-by-step explanation:
Let the number of people were surveyed is x.
We have 60% of x is 48 people.
Set this as equation and solve:
60% of x = 48x*60/100 = 480.6x = 48x = 48/0.6x = 80Correct choice is C.
Answer:
C. 80
Step-by-step explanation:
Given:
60% = 48 peopleLet x be the total number of people surveyed.
Set up a ratio of people to percentage and solve for x:
[tex]\implies \sf 48 : 60 = x : 100[/tex]
[tex]\implies \sf \dfrac{48}{60}=\dfrac{x}{100}[/tex]
[tex]\implies \sf x=100 \cdot \dfrac{48}{60}[/tex]
[tex]\implies \sf x=\dfrac{4800}{60}[/tex]
[tex]\implies \sf x=\dfrac{480}{6}[/tex]

Therefore, the total number of people who were surveyed was 80.
how to find the value of x and z
Answer:
z = 86 °
and, x = 2
Step-by-step explanation:
We know that a straight line is a 180 degree-angle. So, we know that
94 + z must equal 180, because they are the only two angles that make up the straight line.
from this information, (that 94 + z = 180) we can easily find z.
(this is typically an intuitive method of subtracting 94 from 180)
94 + z = 180
-94 -94
z = 86 °
-- we know that the relation between z and (10x + 74) must also be equal to 180, as they make up a straight line
if z = 86, then we can know that (10x + 74) must be equal to
(10x + 74) + 86 = 180
- 86 -86
(10x + 74) = 94
10x + 74 = 94
- 74 - 74
10 x = 20
÷ 10 ÷ 10
x = 2
so, z = 86 °
and, x = 2

Question 2 Determine if (x-3) is a factor to the polynomial P(x) = 2x³ +5x²-28x - 15. (3 marks)
Answer:
(x - 3) is a factor of P(x)
Step-by-step explanation:
if (x - 3) is a factor of P(x) then P(3) = 0
P(3) = 2(3)³ + 5(3)² - 28(3) - 15
= 2(27) + 5(9) - 84 - 15
= 54 + 45 - 99
= 99 - 99
= 0
since P(3) = 0 then (x - 3) is a factor of P(x)
