The altitude of an airplane taking off from an airport is represented by
the equation shown, y = 500x + 1050, where y represents the altitude, in
feet, of the airplane and x represents the number of minutes since take-
off. What is the altitude of the airplane after 5 minutes?
Answer:
3550 ft.
Step-by-step explanation:

Step-by-step explanation:
The future value of the account is given by the formula ...
A = P(1 +r/12)^(12t) . . . . principal P invested at rate r for t years
Solving for t, we find ...
A/P = (1 +r/12)^(12t) . . . . . . . . . . . divide by P
log(A/P) = 12t·log(1 +r/12) . . . . . . take logs
Divide by the coefficient of t, then fill in the numbers.
t = log(A/P)/(12·log(1 +r/12)) = log(202800/93000)/(12·log(1 +.068/12))
t ≈ 11.497
It will take about 11 years for the account balance to reach the desired amount.

The perimeter of a square is given as 8x+20. Write two different expressions for the perimeter. Use factoring to write one of the expressoins. Are the expressions equivalen? Explain
Answer:
P = 4(2x + 5)
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
Step-by-step explanation:
Given that:
Perimeter of square = 4 * s
Where s = side length
If perimeter, P = 8x + 20
Then,
4s = 8x + 20
Divide both sides by 4
4s / 4 = (8x + 20) / 4
s = 2x + 5
P = 4s
P = 4(2x + 5)
Or
P = 2x + 5 in 4 places
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

Step-by-step explanation:
Amir stands on a balcony and throws a ball to his dog, who is at ground level.The ball's height (in meters above the ground), x seconds after Amir threw it, is modeled by How many seconds after being thrown will the ball hit the ground?
Answer:
6 seconds
Step-by-step explanation:
The computation of the number of second would be
In the case when the ball would hit the ground, the ball height would be zero
So the following equation would be
[tex]0 = -(x -2)^2 + 16\\\\(x -2)^2 = 16\\\\x - 2 = \sqrt{16}\\\\x -2 = 4\\\\x = 6[/tex]
So the number of seconds is 6

What is the value of x?
Enter
X :
(Look at the photo)
Answer:
x = 20
Step-by-step explanation:
Each line creates a 180° angle on each side of it. Since these lines intersect, they have congruent angles. This means that these two quantities can be set equal to each other.
3x + 50 = 6x - 10
Solve by combining like-terms and isolating x. Move the 3x to the right by subtracting it from both sides.
50 = 3x - 10
Move the 10 to the left by adding it to both sides.
60 = 3x
Divide the 3 from both sides to isolate the x.
x = 20
Furthermore, this can be checked by plugging in 20 to x and seeing if the expression is true.
3(20) + 50 = 6(20) - 10

Find the marked prices of the following , given the percentage discount and the sale prices: part a: 12% discount , and the sale price $77
part b : 25% discount , and the sale price $123
Answer:
A) $87.5
B) $164
Step-by-step explanation:
A) Marked Price (Original Price)
= [tex]\frac{Sale Price}{1 -Discount}[/tex]
=[tex]\frac{77}{1-0.12}[/tex]
=87.5
B) Marked Price (Original Price)
=[tex]\frac{Sale Price}{1 -Discount}[/tex]
=[tex]\frac{123}{1-0.25}[/tex]
=164

Step-by-step explanation:
the width if a rectangular room is 1 less than twice the length if the perimeter is 196 feet how long is the length
Answer:
l = 33 feet
Step-by-step explanation:
Let length be l.
Width, b = 2l-1
Perimeter of the room, P = 196
We know that the perimeter of the rectangle is given by :
P = 2(l+b)
196=2(l+2l-1)
98=3l-1
Adding 1 both sides.
98+1=3l-1+1
3l=99
l = 33 feet
So, the length of the room is 33 feet.

Solve: 4n - 6 = 12
O n = 4
O n = -4
O n = 4.5
O n=-4.5
Answer:
4.5
Step-by-step explanation:
4n - 6 = 12
add +6 to both sides
4n = 18
divide by 4
4/4n = 18/4
n = 4.5
Mary has 3636 flower pots. She plants daisies in \frac{2}{3} 3 2 of her flower pots. In how many flower pots does Mary plant daisies? Use paper to show your work. Enter your answer in the box.
Answer: 24
Step-by-step explanation:
Number of flower pots = 36
Since she plants daisies in 2/3 of her flower pots, the number of flower pots that Mary plant daisies will be:
= 2/3 × 36
= 2 × 12
= 24
She plants daises in 24 flower pots

Step-by-step explanation:
Given 3 parallel lines intersected by 2 transversals then the parallel lines divide the transversals proportionally, that is
[tex]\frac{3x}{4}[/tex] = [tex]\frac{7.5}{2.5x}[/tex] ( cross- multiply )
7.5x² = 30 ( divide both sides by 7.5 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2
