Item 4 Use a protractor to draw a pentagon so that the top side is horizontal and the left and right sides are perpendicular to the top side. The angles formed at the bottom of the left and right sides each measure 140°. What is the measure of the fifth angle? 72° 80° 88° 92°
Answers
Answer:
80
Step-by-step explanation:
I took the test
The measure of the fifth angle will be 80°. Then the correct option is B.
What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
Let 'n' be the number of sides of the polygon. Then the sum of the interior angles of the polygon is given as,
Sum of angles = (n - 2) × 180°
The sum of the interior angle of the pentagon is given as,
Sum of angles = (5 - 2) × 180°
Sum of angles = 3 × 180°
Sum of angles = 540°
And the diagram is given below. The equation is given as,
x + 90° + 90° + 140° + 140° = 540°
x + 460° = 540°
x = 540° - 460°
x = 80°
The measure of the fifth angle will be 80°. Then the correct option is B.

Alexandra bought a $315,000.00 house, paying 10% down, and financing the rest at 6% interest for 20
years.
A. What is the monthly payment?
Alexandra has a payment of
a month.
B. How much interest will be paid over the life of the loan?
Alexandra will pay
in interest over the life of the loan.
Answers
Answer:
A. payment: $2031.08
B. interest: $203,959.20
Step-by-step explanation:
There are many financial calculators, apps, and spreadsheets that will solve this for you. Here, we will use the amortization formula that would be implemented by one of those.
A.The monthly payment is given by ...
A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . loan of P at rate r for t years
If 10% is put down on the house, then amount that needs to be financed will be ...
$315,000 × (1 -10%) = 0.90 × $315,000 = $283,500
For interest rate 6% and a period of 20 years, the monthly payment is ...
A = $283,500(0.06/12)/(1 -(1 +0.06/12)^(-12·20))
A = $283,500(0.005)(1 -(1.005^-240)) ≈ $2,031.08
__
B.The interest is the difference between the amount repaid and the original loan value:
interest = 240 × $2031.08 - 283,500 = $487,459.20 -283,500
interest = $203,959.20

We can use the given information to set up a ratio...
[tex]\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}[/tex]
[tex]\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}[/tex]
We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):
120 = 4x
Divide both sides by 4

A network administrator uses the function

How long will it take for the virus to spread to 50,000 computers ?
Answers
Functions are used to represent equations and graphs
It will take the virus 10000 hours to spread to 50000 computers
How to determine the number of hoursThe equation of the function is represented as:
f(x) = 5x
When the virus spreads to 50000 computers, the function becomes
50000 = 5x
Rewrite the function as:
5x = 50000
Divide both sides by 5
x = 10000
Hence, it will take the virus 10000 hours to spread to 50000 computers

B.10x = 20
C.12 = 13 - 5x
D.4x = 20
Answers
Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.

Assets are the resources owned by any individual or organization. Svenson's assets increased by $1,400.
What is an asset?An asset is any resource that is been owned by a company, organization, or individual.
Given to us
The original price of the refrigerator is $2,300.
The Market price of the refrigerator is $1,900.
Svensons' paid $500
As it is given to us that the Market price of the refrigerator is $1,400 and as the Svenson's has bought the refrigerator, therefore, this resource(refrigerator) is now owned by the Svenson.
We know that the down payment made is also made from our assets(cash). therefore, the assets increased by $1,400($1900-$500)only.
Thus, the Svensons’ assets increased by $1,400.

Answer:
X = 12 / Y = 49
Step-by-step explanation:
X = 12
This is because one of those angles is a 90 degree angle, and the other is 78; After subtracting them both from 180, you're left with 12
Y= 49
I did the same procedure as above. The two far left lines are equal, which means 41 is also an angle on the other side. 180 - 90 - 41 = 49
