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 rancher plans to use 800 feet of fencing and a side of his barn to form a rectangular boundary for cattle. What dimensions of the rectangle would give the maximum area? What is that area?
SOMEONE PLEASE HELP!
Answer:
the 4 dimensions
Step-by-step explanation:
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.
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

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

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]

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
