At maximum speed, an airplane travels 2460 miles against the wind in 6 hours. Flying with the wind, the plane can travel the same distance in 5 hours, What is the speed of the plane with no wind?

Answers

Answer 1

Answer: 451 miles per hour

distance = rate x time
against the wind this relationship is 2460 = (r-w) x 6
with the wind this relationship is 2460 = (r+w)5

solving those two equations for r (which is the rate the plane flies) gives 902 = 2r which gives r = 451mph.

Area of prism = base area × altitude

1. (2x²-10)(x+4)

= 3x³-2x - 40

2. Base area = 2πr

Volume = (2πr)(r²+ 5r)

=2πr³ + 10πr²

3. Base area=½(6)(x-4)(x+3)=3(x-4)(x+3)

Volume= 3(x-4)(x+3)(⅓)

=(x-4)(x+3)= x² - x -12

4. Base circumference= 10π

Base radius = 10π/(2π) = 5

Base area = πr² = 25π

Volume = 25π(3x²-2x)

=125πx²-50πx

5. Volume = 3π√50

=15π√2

6. Base diameter = 16

Base radius = 16/2 = 8

Base area = 2πr = 16π

Volume = 16π(23a²)

=368πa²

Joe wants to purchase a new skateboard. He already has $40 and can save $20 each week from his job. Write a linear equation to represent the total amount he has after ‘w’ weeks.A) T = 20 + 40w

B) T = 60w

C) T = 40 + 20 + w

D) T = 40 + 20w

Answers

Answer:

Step-by-step explanation:

Joe already has $40 and can save $20 each week. the total amount he can save in a given number of weeks is $20 multiplied by the that number of weeks which in this case is w so 20w. To find the total T of the amount he has after w weeks, you add the amount he already has to the amount saved. So the equation would be T=40+20w

Answer:

D) T = 40 + 20w

What is the slope of the
points (4, -2) and (-4, -4)?

Answers

Answer:

= 1/4

Step-by-step explanation:

We can find the slope given two points by using the following formula

m = (y2-y1)/(x2-x1)

= (-4 - -2)/(-4 -4)

= (-4+2)/(-4-4)

= -2/-8

= 1/4

Answer:

I think the slope is 1/4

Step-by-step explanation:

if you use the slope equation y1-y2/x1-x2, then you get (-2 - -4)/(4 - -4), which is 2/8, which is 1/4
