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

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

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]
A real estate agent believes that the value of houses in the neighborhood she works in has increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market value in the current year to their estimated market value in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. The agent uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈7.496, which has 7 degrees of freedom, determine the range that contains the p-value.
Answer:
The range is [tex]-0.00007 < p-value < 0.00007[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 8
The null hypothesis is [tex]H_o : \mu_d = 0[/tex]
The alternative hypothesis is [tex]H_a : \mu_d > 0[/tex]
The test statistics is [tex]z \approx 7.496[/tex]
The degree of freedom is [tex]df = 7[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(Z > 7.496 )[/tex]
Generally from the t distribution table
(Reference -
danielsoper(dot)com(slash)statcalc(slash)calculator)
the value of [tex]P(Z > 7.496 )[/tex] at a degree of freedom 7 is
[tex]P(Z > 7.496 ) = t_{7.496 , 7 } =0.00007[/tex]
So the range that contains the p -value is
[tex]-0.00007 < p-value < 0.00007[/tex]

How much surface area will be covered in red cloth?
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

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

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.

As part of a survey, 75 people were asked to name their favorite sport. The results showed that 25 of the people named basketball as their favorite sport. What percentage of the people in the survey named basketball as their favorite sport?

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

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.
