This diagram shows a park's walking path in the shaded area.
The outside circumference of the walking path is 50.24 meters and the inside circumference of the walking path is 25.12 meters.
What is the area of this walking path?
Use 3.14 for π.
Enter your answer as a decimal in the box.
Point theif = ban
Answer:
150.72 m²
Step-by-step explanation:
To find the shaded area, calculate the area of the smaller (white) circle and subtract it from the area of the larger circle.
-------------------------------------------------------------------------------------------
Formulae
Area of a circle = [tex]\pi r^2[/tex]Circumference of a circle = [tex]2\pi r[/tex](where [tex]r[/tex] is the radius of the circle)
-------------------------------------------------------------------------------------------
Area of large circle
Given:
circumference = 50.24 m[tex]\pi[/tex] = 3.14⇒ 50.24 = 2 × 3.14 × r
⇒ r = 8 m
Therefore:
⇒ Area = 3.14 × 8²
= 200.96 m²
-------------------------------------------------------------------------------------------
Area of small circle
Given:
circumference = 25.12 m[tex]\pi[/tex] = 3.14⇒ 25.12 = 2 × 3.14 × r
⇒ r = 4 m
Therefore:
⇒ Area = 3.14 × 4²
= 50.24 m²
-------------------------------------------------------------------------------------------
Area of shaded path
area = area of large circle - area of small circle
= 200.96 - 50.24
= 150.72 m²
-------------------------------------------------------------------------------------------

If the convenience store manager expects to sell 540 pieces of candy next week, which is the best
prediction of how many Reese's they should have in the store?
a. 108
b. 135
c. 81
d. 216
Using proportions, considering that one-fourth of the candies they sell is Reese's, the best prediction is given by:
b. 135.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we suppose that it is estimated that one-fourth of the candies they sell is Reese's, hence the best prediction for the number out of 540 pieces is given by:
E = 540 x 1/4 = 540/4 = 135.
Which means that option B is correct.

A cylinder has a height of 7cm.
The circumference of the cylinder is 10pi
Calculate the volume of the cylinder in terms of pi
cm3
Answer:
[tex]175\pi \textsf{ cm}^3[/tex]
Step-by-step explanation:
Circumference of a circle:
[tex]C=2\pi r[/tex] (where [tex]r[/tex] is the radius)
Given circumference = [tex]10\pi[/tex]
[tex]\implies 10\pi=2\pi r[/tex]
[tex]\implies r=5[/tex]
Volume of a cylinder:
[tex]V=\pi r^2h[/tex] (where [tex]r[/tex] is the radius and [tex]h[/tex] is the height)
[tex]\implies V=\pi \cdot5^2\cdot 7[/tex]
[tex]\implies V=175\pi \textsf{ cm}^3[/tex]

Question 3 of 10 If f(x) = 3x – 12, what is f(2)? A. –6 B. 6 C. 18 D. –18
Answer:
Your answer is D
Step-by-step explanation:
f(2) This means that x is 2, so you can plug in 2 for "x" in the equation
f(x) = 3x - 12
f(2) = 3(2) - 12
f(2) = 6 - 12
f(2) = -6

Natalie has a budget of $15,000 dollars to spend on tracking devices to study bison. A radio tracker costs $650 and a GPS tracker costs $1400. Natalie wants to buy at least 9 radio trackers and more than 3 GPS trackers. The following system of inequalities represents this situation, where x is the number of radio trackers and y is the number of GPS trackers. x ≥ 9 y > 3 650x + 1400y ≤ 15000

x2 − 15x = −50 A) x = 3, x = 5 B) x = 5, x = 10 C) x = 3, x = −5 D) x = −5, x = −10
Answer:
x = 10 or x = 5 thus: B is the answer
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 15 x = -50
Add 225/4 to both sides:
x^2 - 15 x + 225/4 = 25/4
Write the left-hand side as a square:
(x - 15/2)^2 = 25/4
Take the square root of both sides:
x - 15/2 = 5/2 or x - 15/2 = -5/2
Add 15/2 to both sides:
x = 10 or x - 15/2 = -5/2
Add 15/2 to both sides:
Answer: x = 10 or x = 5

Answer: X=6 AB= 52
Step-by-step explanation:
7x + 10 = 9x -2 (because the sides are equal) & solve.
subtract the 7x on both sides.
10 = 2x -2
add 2 on both sides
12 = 2x
divide by 2
x = 6
Answer:
x = 4
AB = 52
Step-by-step explanation:
The dashes on the line segments AB and BD mean that they are equal in length.
⇒ 7x + 10 = 9x - 2
Add 2 to both sides:
⇒ 7x + 10 + 2 = 9x - 2 + 2
⇒ 7x + 12 = 9x
Subtract 7x from both sides:
⇒ 7x + 12 - 7x = 9x - 7x
⇒ 12 = 2x
Divide both sides by 2:
⇒ 12 ÷ 2 = 2x ÷ 2
⇒ 6 = x
⇒ x = 6
Substitute x=6 into the expression for AB to find the length of AB:
⇒ AB = 7(6) + 10
⇒ AB = 42 + 10
⇒ AB = 52
An airplane travels at a speed of 582 miles per hour to reach its destination in 4 hours. Determine the duration of the flight, if the airplane travels at a speed of 388 miles per hour.
Answer: 6 Hours
Step-by-step explanation:
It takes 6 hours to reach the destination when traveling at 388 mph.
Speed is the ratio of total distance traveled to the total time taken It is given by:
Speed = distance/time
Given that it takes 4 hours to reach a destination when travelling at 582mph, hence the distance is:
582 = distance / 4
distance = 2328 miles
If travelling at 388 mph, the time is:
388 = 2328 / time
time = 6 hours
Hence it takes 6 hours to reach the destination when traveling at 388 mph.
Answer:
the answer is 6
Step-by-step explanation:
speed is the ratio of total distance traveled to the total time taken It is given by: speed = distance/time
given that it takes 4 hours to reach a destination when travelling at 582 mph, hence the distance is:
582 = distance / 4
distance = 2328 miles
if travelling at 388 mph, the time is:
388 = 2328 / time
time = 6 hours

The length of a rectangle is 8 ft longer than twice the width. If the perimeter is 64 ft, find the length and width of the rectangle.
Answer:
Length: 24 feet
Width: 8 feet
Step-by-step explanation:
ok so first let the width be x. so if the width is x then the length would be 2x+8. If the perimeter is 64 you would divide it by two because it goes all the way around the rectangle. so then you have 32=(2x+8)+x. then we solve for x.
32=(2x+8)+x
32=3x+8
-8 -8
------------------
24=3x
8=x
now you have x=8 so that is the width. then you have the length so then you fill x in 2*8+8 is the length and your length would be 24.

A. 57.76 cm²
B. 86.64 cm²
C. 144.4 cm²
D. 361 cm²
Answer:
86.64 cm
Step-by-step explanation:
i have no idea i guessed on got it right on the quiz
The surface area of the red cloth of 60% paperweight is 86.64 square cm. Then the correct option is B.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The surface area of the paperweight will be given as
[tex]\rm Surface \ area = 2\times (5*3 + 6*3) + 5*6 + 2 \times \dfrac{1}{2} * 5 * 2 + 2 \times (3.2 + 6)\\\\Surface \ area = 2 \times (33) + 30 + 2 \times 5 + 2\times 19.2\\\\Surface \ area = 66 + 30 + 10 + 38.4\\\\Surface \ area = 144.4[/tex]
This figure represents a small paperweight.
The plan is to cover 60% of the total surface area, including the bottom face, of the paperweight with red cloth.
The surface area of the red cloth will be
Surface area of red cloth = 0.6 × 144.4
Surface area of red cloth = 86.64 cm²
