What is the perimeter and area of the photo below? And please show me how you did it. I need it for a school math group, and I’m struggling. So please show work.
Answer:
Assuming the area is made up of a square and a semicircle.
Perimeter
The side length of the square = 18 ft
We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).
⇒ perimeter of the square = (3 x 18) + (18 - 12)
= 54 + 6
= 60 ft
Circumference of a circle = [tex]\pi[/tex]d (where d is the diameter)
⇒ arc length of the semicircle = 1/2 circumference
= 1/2 · [tex]\pi[/tex] · 12
= 6[tex]\pi[/tex] ft
Total perimeter = 60 + 6[tex]\pi[/tex] = 78.8 ft (nearest tenth)
Area
Area of a square = s² (where s is the side length)
⇒ area of square = 18²
= 324 ft²
Diameter = 2r ⇒ r = 1/2 diameter
Area of a circle = [tex]\pi[/tex]r² (where r is the radius)
⇒ area of the semicircle = 1/2 · [tex]\pi[/tex] · 6²
= 18[tex]\pi[/tex] ft²
Total area = 324 + 18[tex]\pi[/tex] = 380.5 ft² (nearest tenth)

What is the volume?The volume is a measurement of three-dimensional space that is utilized.
Let r be the radius and h be the height of the cylinder and cone. Then the volume of the cylinder will be given as,
Volume of A = π r²h cubic units ...1
And the volume of the cone will be given as,
Volume of B = (1/3) × r²h cubic units ...2
From equations 1 and 2
Volume of B = 3 x volume of A

[tex](5, 7), (-8, -4)[/tex]
Answer:
[tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex]
Step-by-step explanation:
y= mx +c, where m is the slope and c is the y-intercept.
We need to find the value of m and c, which can be done by using the slope formula and by substituting a pair of coordinates respectively. Find m first before finding the value of c.
[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
[tex]slope = \frac{7 - ( - 4)}{5 - ( - 8)} [/tex]
[tex]slope = \frac{7 + 4}{5 + 8} [/tex]
[tex]slope = \frac{11}{13} [/tex]
Substitute the value of m into the equation:
[tex]y = \frac{11}{13} x + c[/tex]
Substitute a pair of coordinates:
When x= 5, y= 7,
[tex]7 = \frac{11}{13} (5) + c[/tex]
[tex]c = 7 - \frac{55}{13} [/tex]
[tex]c = \frac{91}{13} - \frac{55}{13} [/tex]
[tex]c = \frac{36}{13} [/tex]
[tex]c = 2 \frac{10}{13} [/tex]
Thus, the equation of the line is [tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex].

Answer:
there are three ( 3 ) possible outcomes that are 1,2 and 3
Typically, I would say 3. So there's always that. But it could also be 4 because your spinner could land on a line. So I would say either 3 or 4.
Complete the equation and match it to its corresponding number of solutions.
Answer:
A and infinite solutions
Step-by-step explanation:
4/5x - 8 = 4(1/5x - 2)
4(1/5x - 2)
4/1 x 1/5x = 4/5x
4 x (-2) = -8
Put them together and you get:
4/5x - 8 AND
4/5x - 8 = 4/5x - 8
IF 2 SIDES OF AN EQUATION ARE THE SAME THEN THE ANSWERS ARE INFINITE
YOU CAN TURN THE EQUATION INTO JUST (x = x)
Answer
B and One Solution
Step-by-step explanation:
4/5x - 8 = -(4/5x + 2)
-(4/5x + 2) = -4/5x - 2
ADD 4/5x TO THE BOTH SIDES
8/5x - 8 = -2
ADD 8 TO BOTH SIDES
8/5x = 6
DIVIDE BOTH SIDES BY 8/5 OR 1.6
x = 3.75

Draft a small paragraph Explaining the concept of ground speed and horizontal distance traveled or distance traveled over the earth. Consider in your description what information is needed to calculate distance traveled.
Answer:
miles to travel directly south = 54 miles (to the nearest mile)
extra miles = 68 miles (nearest mile)
Step-by-step explanation:
We need to find the height of the right triangle in the diagram.
To do this, use the sine trig ratio.
[tex]\sin(x)=\sf\dfrac{O}{H}[/tex]
where:
[tex]x[/tex] is the angleO is the side opposite the angleH is the hypotenuseGiven:
[tex]x[/tex] = 27°
O = height (h)
H = 120 miles
Substituting the given values into the formula:
[tex]\implies \sin(27^{\circ})=\sf\dfrac{h}{120}[/tex]
[tex]\implies \sf h=120 \sin(27^{\circ})[/tex]
[tex]\implies \sf h=54.47885997...[/tex]
Therefore, the shipmate will have to travel 54 miles (to the nearest mile) directly south.
To find the number of extra miles have been traveled, we first need to find the base length of the right triangle.
To do this, use the cos trig ratio.
[tex]\cos(x)=\sf\dfrac{A}{H}[/tex]
where:
[tex]x[/tex] is the angleA is the side adjacent the angleH is the hypotenuseGiven:
[tex]x[/tex] = 27°A = base (b)H = 120 milesSubstituting the given values into the formula:
[tex]\implies \cos(27^{\circ})=\sf\dfrac{b}{120}[/tex]
[tex]\implies \sf b=120 \cos(27^{\circ})[/tex]
[tex]\sf \implies b=106.9207829...[/tex]
Therefore, the base of the right triangle is 106.9207829... miles
To find the extra miles, sum the hypotenuse and the height of the triangle, then subtract the base.
Extra miles = (120 + 54.47885997... ) - 106.9207829...
= 67.55807707...
= 68 miles (nearest mile)

For this item, enter the answer in the space provided. A college student earns $ 15, 000 working part-time at a bookstore. The student pays 1/10 of the earnings in taxes, spends 2/5 of the earnings on living expenses, and saves the remainder of the earnings. How much money does the student save?
Answer: 10,500
Step-by-step explanation:
How to calculate tax and earning
Given the following paramiters
Total amount earned by the student = $15000
Assume we have the following parameters
Earning paid off in taxes = $1500
Amount spent on living expenses = $3000
Amount she will have left = 15000 - (1500 + 3000)
Amount she will have left = 15,000 - 4500
Amount she will have left = 10,500
Hence the amount she will have left is $10,500
Answer:
$7,500
Step-by-step explanation:
First, find the amount he pays in taxes:
$15,000 x 0.1 = $1,500
Next, find the amount he pays in living expenses:
$15,000 x 0.4 = $6,000
Add the two amounts together:
$1,500 + $6,000 = $7,500
Subtract the combined amount from the original amount to find how much the student saved:
$15,000 - $7,500 = $7,500
Therefore, the college student saves $7,500.

Explain what πr² and h represent in terms of the cylinder. Then explain how this information is used to find the formula for the volume of a half sphere, 2/3 • πr²• r. Then explain how you use this formula to get the formula 4/3 πr³ for the volume of a sphere.
Answer:
The formula that is used to determine the volume of the cylinder in terms of pi is V = πr2h cubic units where, "V", "r" and "h" are the volume, radius, and height of the cylinder. This formula of volume of the cylinder also shows its dependence on the radius and height of the cylinder.

Answer:
x = 37°
x = 40°
x = 260°
Step-by-step explanation:
To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.
Question 1
[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]
Question 2
To find the bigger arc, subtract the smaller arc from 360°
⇒ 360° - 140° = 220°
[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]
Question 3
The smaller arc can also be found by subtracting the external angle from 180°
Smaller arc = 180° - 80° = 100°
[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]
[tex]160^{\circ}=x-100^{\circ}[/tex]
[tex]x=260^{\circ}[/tex]
#1
2x=128-542x=74x=37°#2

(05.03)Bev has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.
Answer:
220.5 sq feet
Step-by-step explanation:
Given : Bev has to cut her grandma's grass this weekend
Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.
To Find : Area of Polygon
Solution:
Area of triangle = (1/2) bh
= (1/2) * 15 * 15
= 112.5 sq feet
= (1/2) * 4 * 4
= 8 sq feet
Area of rectangle = 25 x 4 = 100 sq feet
Total area =112.5 + 8 + 100
= 220.5 sq feet
Area of Polygon = 220.5 sq feet
Answer:
398 ft²
Step-by-step explanation:
Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.
Triangle area = 1/2·bh
Rectangle area = bh
___
So, the first triangle has an area of ...
1/2·(20 ft)(20 ft) = 200 ft²
The second triangle has an area of ...
1/2·(6 ft)(6 ft) = 18 ft²
The rectangle has an area of ...
(30 ft)(6 ft) = 180 ft²
And the area total is ...
200 ft² +18 ft² +180 ft² = 398 ft²
