Using the properties of alternate angles, the value of x = 8 and ∠ A = 30
What are Alternate Angles?A transversal that crosses two parallel lines produces alternate exterior angles. They form two pairs (four total angles) of alternate outside angles since they are situated "outside" the two parallel lines but on different sides of the transversal.
For the given question,
∠A=6x−18
∠B=14x+38
As, both parallel lines are intersected by a transversal,
the value of angle ∠A and ∠180 - B is same as they are alternate angles,
⇒ 6x−18 = 180 - 14x - 38
⇒ 6x + 14x = 142 + 18
⇒ 20x = 160
⇒ x = 8
∠A = 6x−18
⇒ ∠ A = 30

Answers
The total surface area Paul is required to paint is 36 yard square.
How to find surface area?He needs to buy paint to cover all outside surfaces of his shed .
2 sides of shed are rectangles with a base of 12ft and a side of 6 ft.
Therefore,
area of a rectangle = lw
where
l = lengthw = widtharea of the rectangle = 12 × 6
area of the rectangle = 72 ft²
The rectangle are two.
Hence, area of the two rectangular faces = 72 + 72 = 144 ft²
The other two sides are squares with sides of 6 ft.
Therefore,
area of the two squares = 6² + 6² = 36 + 36 = 72 ft²
The roof consists of four triangles,
2 of the triangles have a base of 6 feet and a height of 6 feet.
Therefore,
area of the two triangles = 2 (1 / 2 × 6 × 6) = 36 ft²
The other two triangles have a base of 12 ft and a height of 6 ft.
area of the other triangle = 2(1 / 2 × 12 × 6) = 72 ft²
Hence,
total area the paint will cover = 72 + 36 + 72 + 144 = 324 ft² = 36 yard²

Answer:

13. 50%
14. 0.15%
15. 8 students
Step-by-step explanation:
Given a normal distribution with mean 20 and standard deviation 5, you want several probabilities based on the empirical rule.
Empirical ruleThe empirical rule tells you the percentages of a normal distribution that are within 1, 2, or 3 standard deviations of the mean. They are ...
within 1: 68%within 2: 95%within 3: 99.7%12. Between 15 and 25Wait times between 15 and 25 are within 20±5, so within 1 standard deviation of the mean. The percentage of students waiting 15–25 minutes is 68%.
13. Less than 20The mean of the distribution is 20, which is its line of symmetry.
50% of students will wait less than 20 minutes.
14. More than 3535 is 3 standard deviations above the mean, so the fraction in this group is half of the difference between 1 and 99.7%.
0.15% of students will wait more than 35 minutes.
15. How many?Of 5300, the number waiting more than 35 minutes is ...
0.15% × 5300 = 7.95 ≈ 8
About 8 students will wait more than 35 minutes.

These values are based on the empirical rule, as required by the problem statement. The actual number for P(Z>3) is about 0.0013499 (0.13%), and the number of students is about 7.15 ≈ 7.

The order of the values using the basic unit of meters from smallest to largest. is: 109000 mm < 2.6 km < 41.7 hm
What are the units of measurement of distance or length?
Distance is the gap between any two points under consideration.
The basic unit for measuring distance is the meter.
There are larger as well as smaller units for measuring length or distance which are based on the unit of meter.
The units are as follows:
millimeter, mm = 0.001 m
centimeter, cm = 0.01 m
decimeters, dm = 0.1 m
meter, m = 1 m
kilometer, km = 1000 m
hectometer, hm = 100 m
Now to compare the given quantities making the units same as two quantities can only be compared only when there units are same :
Considering the given values;
2.6 km = 2600 m
109,000 mm = 109 m
41.7 hm = 4170 m
Therefore, after comparison arranging the quantities in order from smallest to largest is 109000 mm < 2.6 km < 41.7 hm

In the game of baseball, home plate is a pentagon.What is the measure of the angle at the bottom of home plate?A. 60°B. 90°C. 120°D. 135°
Answers
EXPLANATION
Since the figure is like a pentagon, we need to add the interior angles in order to get the needed angle.
The first part of the figure is composed of a square with two right angles of 90 degrees and two angles of 135, making a total of 90+90+135+135 = 450 degrees.
The left needed angle should add a total of 540 degrees, by the Sum of Interior Angles of a Pentagon Theorem, as follows:
450 + bottom angle = 540
Subtracting -450 to both sides:
bottom angle = 540 - 450
Subtracting angles:
bottom angle = 90 degrees
In conclusion, the value of the bottom angle is 90 degrees.

an oil-well contracted drills a shaft 7 meters deeper into the ground every 2 hours.Wich has a graph that best represents this rate?
Answers
If an oil-well contracted drills a shaft 7 meters deeper into the ground every 2 hours, then Graph H best represents this rate.
The graphs are attached
Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours,
hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour
Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per hour
The slope (rate of change) of a line (m) is given by:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:
Slope of the line , [tex]m = \frac{-20 - 0}{10 - 0}[/tex]
Slope of the line is - 2 meters per hour
b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:
Slope of the line, [tex]m = \frac{-70 - 0}{10 - 0}[/tex]
Slope of the line is -7 meters per hour
c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:
Slope of the line, [tex]m = \frac{-35 - 0}{10 - 0}[/tex]
Slope of the line is -3.5 meters per hour
d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:
Slope of the line, [tex]m = \frac{-3.5 - 3.5}{10 - 0}[/tex]
Slope of the line is 0 meters per hour.
Therefore, if an oil-well contracted drills a shaft 7 meters deeper into the ground every 2 hours, then Graph H best represents this rate.

Four Rivers offers 8% interest compounded quarterly. Melvin has $10,000 to invest. He expects to withdraw the money at the end of 4 years. Which bank gives Melvin the better deal?
Answers
The better deal between the offer at Mystic Bank and Four Rivers Bank is the deal at Mystic Bank.
What is the better deal?In order to determine which bank has the better offer, the future value of the investment options have to be determined.
The future value of an investment is a function of the amount investment, the number of compounding, the years of the investment and the interest rate.
When an investment is compounded semi-annually, it means that it grows exponentially twice in a year. When an investment is compounded quarterly, it means that is grows exponentially four times in a year.
The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate m = number of compoundingN = number of yearsInterest rate at Mystic bank = 10% /2 = 5%
Interest rate at Four Rivers Bank = 8% / 4 = 2%
Future value of the investment at Mystic bank :

Explain how to find the cost of the fabric needed to make the table cloth.

A)
In order to check this sentence, we need to convert the value from foot to yard.
Knowing that 1 yard is equal 3 feet, we have that:
[tex]3\text{ yards 1 foot}=3\cdot3\text{ feet + 1 foot}=9\text{ feet + 1 feet}=10\text{ feet}[/tex]So Debbie's affirmation is incorrect, therefore we disagree.
B)
First we need to calculate the area of the table cloth.
Converting the length to foot, we have:
[tex]4\text{ yards}=4\cdot3\text{ feet}=12\text{ feet}[/tex]Now, calculating the area (which is the product of the length and the width), we have:
[tex]\text{Area}=10\cdot12=120\text{ ft}^2[/tex]If each square foot is $0.25, we just need to multiply the area by the cost of one square foot in order to find the cost of the fabric for the table cloth:

Two possible diagrams of the triangle are shown below
To find angle B in each triangle, we would apply the law of sines which is expressed as
a/SinA = b/SinB = c/SinC
For either of the triangles, by applying the sine law, we have

By crossmultiplying, we have
32 SinB = 33 Sin 64
Sin B = (33 Sin 64)/32 = 0.9269
We would find angle B by finding the inverse of sine 0.9269
Thus,
B = Sin^-1(0.9269) = 68
