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°
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.

What is a quadratic equation?A quadratic equation is one with a single degree 2-variable and has the general form [tex]a x^{2} + bx + c = 0.[/tex] a, b, and c is the constant value, and x consists of a variable.
The quadratic equation's x-intercepts are (-5, 0). That indicated that the quadratic equation's two elements are (x + 5) and (x -0).
f(x) = a (x + 5) (x - 0) (x - 0)
= ax+5a
f(x) = [tex]ax^{2} +5x[/tex]
The quadratic equation's graph goes through (4, 0). Therefore, we must change equation 1 to read x = 4 and f(x) = 0.
0 = a × 4² + (5 × 4)
0 = a × 16 +20
a = [tex]\frac{-20}{16}[/tex]
=-1.25
The quadratic equation is known to have the form ax² + bx + c = 0.
f(x) = -1.25[tex]x^{2}[/tex] + 5x
Consider y= F(x)
∴ The required quadratic equation of function in the standard form is Y = -1.25 x² + 5x.

Paul needs to buy paint to cover all outside surfaces of his shed, depicted below. How much area, in square yards, does he need to cover?
2 sides of shed are rectangles with a base of 12ft and a side of 6 ft.
The other two sides are squares with sides of 6 ft.
The roof consists of four triangles, 2 of the triangles have a base of 6 feet and a height of 6 feet.
The other two triangles have a base of 12 ft and a height of 6 ft
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

Explain wether you agree or disagree with Debbie. Part B. The cost of the fabric used to make the tablecloth is $0.25 per square foot. 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:
[tex]\text{Cost}=120\cdot0.25=30[/tex]So the cost is $30.

12–15. Melvin Indecision has difficulty deciding whether to put his savings in Mystic Bank or Four Rivers Bank. Mystic offers 10% interest compounded semiannually. 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?
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 :
$10,000 x (1.05)^(2 x 4) = $14,774.55
Future value of the investment at Four Rivers Bank :

There would be 20 guests for the restaurants to cost the same
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the number of guests?From the question, we have the following parameters:
Red Lobster
Rate per person = $30
Set up fee = $100
Olive Garden
Rate per person = $25
Set up fee = $200
So, the equations of the restaurants are
Red Lobster = 30g + 100
Olive Garden = 25g + 200
Where the number of guests is g
When the restaurants cost the same amount, we have
Red Lobster = Olive Garden
Substitute the known values in the above equation
So, we have
30g + 100 = 25g +200
Evaluate the like terms
5g = 100
Divide by 5
g = 20
Hence, the number of guests is 20

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?
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.
