Answer:
perimeter is 36
Step-by-step explanation:
if x=3
then it turns into
Width 7-2(3)
length 5(3)+2
which equals
width 1
length 17
since it's a perimeter you add all four corners
which is 1+1+17+17=36
The Sausage Hut is looking at a new sausage system with an installed cost of $330,000. This cost will be depreciated straight-line to zero over the project's three-year life, at the end of which the sausage system is estimated to have zero value. The project has no impact on net working capital. Each year during its three year life, the new system will increase the firm’s Sales by $455,000 and its Operating Cash Flow by $123,300.
If the tax rate is 30 percent and the discount rate is 9 percent, what is the NPV of this project?
Group of answer choices
-111,524
- $17,891
$19,405
$35,389
$1,136,217
Based on the net cashflow over the three year life, the NPV that Sausage Hut will realize is -$17,891.
What is the Net Present Value?First find the present value of the increased cashflows. As it is a constant amount of $123,300, we can treat it as an annuity.
Present value = Amount x (Present value of annuity interest factor, 9%, 3 years)
= 123,300 x 2.5313
= $312,109.29
The net present value is:
= Present value of cashflows - Amount invested
= 312,109.29 - 330,000
= -$17,890.71
= -$17,891.
In conclusion, option B is correct.

Hello! Here are your answers for Part A:
4(x + 6) - 11 = 25 is a multi-step equation.
-1/2(2/3a - 4) = 1/2a - 7 is an equation with rational coefficients.
y - 23 = 8 is a one-step equation.
-3m - 2 = -17 is a two-step equation.
For Part B:
Find the common denominator -
x/2 - 7 = 4
x/2 + 2(-7)/2 = 4
Combine the fractions with the common denominator -
x/2 + 2(-7)/2 = 4
x + 2(-7)/2 = 4
Multiply the numbers -
x + 2(-7)/2 = 4
x - 14/2 = 4
Multiply all terms by the same value to eliminate fraction denominators -
x - 14/2 = 4
2 * x - 14/2 = 2 * 4
Cancel multiplied terms that are in the denominator -
2 * x - 14/2 = 2 * 4
x - 14 = 2 * 4
Multiply the numbers -
x - 14 = 2 * 4
x - 14 = 8
Add 14 to both sides -
x - 14 = 8
x - 14 + 14 = 8 + 14
Simplify -
x - 14 + 14 = 8 + 14
x = 8 + 14
x = 22
The solution to this equation is 22. 6 is NOT a solution.
Hope this helps! Have a great day.

O y = -x + 10
O y = 10x + 1
O y=-10x - 9
O y=-5x - 9
Answer:
y = -5x + 9.
Step-by-step explanation:
Lets look for the relation between x and y.
Try the first one:
When x = -2, y = -(-2) + 10 = 12
In the table y = 1 so its not this one.
Number 2:
x = -2, y = 10(-2) + 1 = -18 - Not thios one
Number 3:
When x = -2, y = -10(-2) - 9 = 11
Not this one
Number 4:
y = -5(-2) - 9 = 1
This is the one.
Check again with x = 0:
When x = 0, y = -5(0) - 9 = -9.

and has a diameter of 1.5 centimeters?
7.57 cm
B 8.6257 cm
C 10.57 cm
D 19.557 cm
To find the surface area:
⇒ let's define what makes up the surface area of a cylinder
⇒ it is made up of two circles as its bases and its side is a long
rectangular piece curved around
Area of Two Circles
⇒ Area of Circle Formula = [tex]\pi r^{2}[/tex]
⇒ Area of Two Circle Formula = [tex]2\pi r^{2}[/tex]
⇒ since r: is length of radius --> 0.75 cm (radius is half of diameter)
⇒ Area of Two circles: [tex]2\pi (0.75)^{2} =3.5343[/tex]
Area of Rectangular piece curved around to form Cylinder
⇒ length: circumference of a circle ⇒ [tex]2\pi r[/tex]
⇒ width: height of the cylinder ⇒ 5cm
⇒ Area of Rectangular piece: [tex]2*\pi *0.75*5=[/tex] 23.5169

The GRE is an entrance exam that many students are required to take in order to apply to graduate school. In 2014, the combined scores for the Verbal and Quantitative sections were approximately normally distributed with a mean of 310 and a standard deviation of 12.
What is the probability that a randomly selected score is greater than 334? Write your answer as a decimal
Using the normal distribution, it is found that there is a 0.0228 probability that a randomly selected score is greater than 334.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 310, \sigma = 12[/tex]
The probability that a randomly selected score is greater than 334 is one subtracted by the p-value of Z when X = 334, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{334 - 310}{12}[/tex]
Z = 2
Z = 2 has a p-value of 0.9772
1 - 0.9772 = 0.0228.
0.0228 probability that a randomly selected score is greater than 334.

The value of (1/2)x⁴ - (1/4)x² when x = 2 is 7.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is (1/2)x⁴ - (1/4)x².
We have to calculate the value of the expression when x = 2.
Substitute x = 2 in the expression.
(1/2)x⁴ - (1/4)x² = (1/2) (2)⁴ - (1/4) (2)²
= (1/2) × 16 - (1/4) × 4
= 16/2 - 4/4
= 8 - 1
= 7
Hence the value of the expression when x = 2 is 7.

What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
Length = 10 ft 9in
Width = 15ft 3 in
a.
Perimeter = 2 (Length + Width)
Length = 10 ft 9 in = (10 x 12) + 9 = 129 in.
Width = 15 ft. 3 in. = (15 x 12) + 3 = 183 in
Perimeter.
= 2(129 + 183)
= 624 in.
b.
Area = Length x Width
Area = 129 in. x 183 in
Area == 23,607 in²
Each tile covers an area of 6 in. x 6 in
Area of tiles = 36 in²
So,
The number of tiles required.
= Area ÷ Tile area
= 23,607 in² ÷ 36 in²
≈ 656.3 tiles.

Arrange the three side
lengths in increasing
order.
Answer:
a < c < b
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°
Therefore, the measure of the missing angle (opposite side c) is:
180° - 69° - 54° = 57°
Relationship between sides and interior angles of any triangle:
The shortest side is always opposite the smallest angleThe longest side is always opposite the largest angleTherefore, from inspection of the triangle:
a is opposite the smaller angle of 54°c is opposite the angle of 57°b is opposite the largest angle of 69°So the side lengths in increasing order are:
a < c < b
Rest angle:-
180-(69+54)180-12357Note that smaller side has smaller opposite angle
Hence the order is
a<c<b
