Yes, because the 16 feet ladder will reach to the window that is 14.5 feet above the ground.
What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle equals the sum of the squares of the other two sides.
The hypotenuse of a triangle, which has a straight angle of 90 degrees, has a square that, according to the Pythagoras theorem, equals the sum of the squares of the other two sides.
According to the question;
A 20-foot ladder is leaning against the side of a house.
Hypotenuse H= 20 feet
The bottom of the ladder is 12 feet from the base of the house.
Base B = 12 feet
And let P be the perpendicular.
Using Pythagoras theorem
H²= P² + B²
20² =12² +P²
P²= 400-144
P²= 256
Taking the square root.
P= 16 feet.
Since the height of the ladder is 16 feet, and we have to reach 14.5 feet above the ground.
16 > 14.5
That means, the ladder will reach to the window.
Hence, Yes, the 16 feet ladder will reach to the window.

A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change
Answer:
The percent of change is 22.22%.
Step-by-step explanation:
You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:
percent of change=((1,100-900)/900)*100
percent of change=(200/900)*100
percent of change=22.22%
According to this, the answer is that the percent of change is 22.22%.

a rectangle has a length of 25x^3 and a width of 5x^2. Fkns the area.
Answer:
Step-by-step explanation:
I hope you want the area.
Area = L * W
L = 24x^3
W = 5x^2
Area = 24x^3 * 5x^2
Area = 120 * x^(3 + 2)
Area = 120 * x^5
Note
When you multiply numbers or letters that have powers, if the base for both of them is the same, the powers are added.
The above answer is an example x^2 * x ^3 are letters (x) that are raised to the 2nd power and the 3rd power. You add the powers.
Numbers can do the same thing
2^5 * 2^3 = 2^82*8 = 2562^5 = 642^3 = 864 * 8 = 256

Solve the following system of equations by substation.
5y = 7x + 22
x = -6y + 17
A. (2,-1)
B. (5,3)
C. (-1,3)
D. (-1,4)
Answer:
C. (-1, 3)
Step-by-step explanation:
Label the 2 equations:
5y= 7x +22 -----(1)
x= -6y +17 -----(2)
Substitute (2) into (1):
5y= 7(-6y +17) +22
5y= -42y +119 +22 (Expand bracket)
5y= -42y +141 (Simplify)
42y +5y= 141 (+42y on both sides)
47y= 141
y= 141 ÷47 (÷47 on both sides)
y= 3
Substitute y= 3 into (2):
x= -6(3) +17
x= -18 +17
x= -1
Thus, the solution is (-1, 3).

Answer:
336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
336 cm^2

In the equation y = kx, what does the variable k represent?
A. The dependent variable
B. The constant of variation
C. The independent variable
D. The direct variation equation
Answer:
I think it B but I really don't know cause need like an example
The k in the equation represents Option B) The constant of variation
What is a constant in an equation?A constant is a value or number that never changes in expression; it's constantly the same. For example, 36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.
Given here the equation y=kx where k is the slope and a scalar value thus it is independent of x and y and thus is a constant.
Hence, The k in the equation represents Option B) The constant of variation
