Answer: x=12
Step-by-step explanation:
The Pythagorean theorem is a²+b²=c². A and b are the legs, and c is the hypotenuse. Since we are only given the length of a leg and hypotenuse, we fill in what we have and solve for a.
a²+16²=20² [exponent]
a²+256=400 [subtract both sides by 256]
a²=144 [square root both sides]
a=12
Now, we know the missing leg, x=12.

1. Suppose that during its flight, the elevation e (in feet) of a certain airplane and its timet
in minutes since takeoff, are related by a linear equation. Consider the graph of this
equation, with time represented on the horizontal axis and elevation on the vertical
axis. For each situation, decide if the slope is positive, zero, or negative.
a. The plane is cruising at an altitude of 37,000 feet above sea level.
b. The plane is descending at rate of 1000 feet per minute.
c. The plane is ascending at a rate of 2000 feet per minute.
Answers
Answer:
A:zero
B:negative
C:positive
Step-by-step explanation:
the key words just tell you for A it was cruising B it was negative because descending and C is positive because ascending.
The correct explanation for the slope will be;
a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.
b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.
c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.
What is mean by Slope?
The slope of line is a measure of its steepness.
Given that;
During its flight, the elevation e (in feet) of a certain airplane and its time
in minutes since takeoff, are related by a linear equation.
In the graph, time represented on the horizontal axis and elevation on the vertical axis.
Now,
a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.
Because the plane is cruising.
b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.
Because the plane is descending.
c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.
Because the plane is ascending.
Thus, The correct explanation for the slope will be;
a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.
b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.
c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

You probably forgot to mention the options. After a little research, I was able to get the complete question with the mentioned options you should have mentioned. The potential complete question is:
Ellen plans to leave an 18 percent tip with her $23.75 lunch bill. Which of these expressions could she use to determine her total bill?
Check all that apply.
(1.18)(23.75) 23.75 – [(0.18)(23.75)] 23.75 + [(0.18)(23.75)] (0.18)(23.75)
Answer:
The expression [tex]23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex] will determine her total bill.
Step-by-step explanation:
Total lunch bill = $23.75
As he pans to 18% tip of the total bill, so the expression will be:
[tex]=23.75\:+\:\left(\:18\%\:\:of\:\:23.75\:\right)[/tex]
[tex]=23.75\:+\:\left(\:\frac{18}{100}\:\times \:23.75\:\right)[/tex]
[tex]=23.75\:+\:\left(\:0.18\times \:23.75\:\right)[/tex]
or
[tex]=23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex]
Therefore, the expression [tex]23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex] will determine her total bill.

I need help with slope
Answers
Answer:
Step-by-step explanation:
Slope means x there are many ways to find the slope like using the slope formula y2-y1/x2-x1 or using rise over run
Hope this help :)
Answer:
Rise over run
Step-by-step explanation:
So what the Rise is, is the point on which the line is persicly on point with they grid of your graph / how high also the distance on the y axis. The run is the how far also known as the x axis.
so if we had a slope of 2/3
it would be a posative slope it wod go up 2 and to the right 3 to the next intersection of the y ad the x axis'

2x-4y=8 and 7x-3y=61 solve by substitution
Answers
Answer:
(10, 3)
Step-by-step explanation:
Solve by Substitution
2x − 4y = 8 and 7x − 3y = 61
Solve for x in the first equation.
x = 4 + 2y 7x − 3y = 61
Replace all occurrences of x with 4 + 2y in each e quation.
Replace all occurrences of x in 7x − 3y = 61 with 4 + 2y. 7 (4 + 2y) − 3y = 61
x = 4 + 2y
Simplify 7 (4 + 2y) − 3y.
28 + 11y = 61
x = 4 + 2y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
11y = 33
x = 4 + 2y
Divide each term by 11 and simplify.
y = 3
x = 4 + 2y
Replace all occurrences of y with 3 in each equation.
Replace all occurrences of y in x = 4 + 2y with 3. x = 4 + 2 (3)
y = 3
Simplify 4 + 2 (3).
x = 10
y = 3
The solution to the system is the complete set of ordered pairs that are valid solutions.
(10, 3)
The result can be shown in multiple forms.
Point Form:
(10, 3)
Equation Form:
x = 10, y = 3
X=8+4y/2 so X= 4+2y. (Divide both sides by 2)
Sub in 4+2y for x so 7(4+2y)-3y=61
Distribute: 28+ 14y -3y=61
Subtract 28 and add the y’s. 11y=33
Y=3

Blas y Raul se han colocado en línea recta en lados opuestos de un generador eólico para medir su altura el terreno es llano y los dos amigos están separados por 41 m cada uno desde su posición mide el ángulo con el que se ve el generador desde el suelo qué altura tiene el generador
Answers
Answer:
La pregunta esta incompletea porque no incluye el angulo de Raul y el angulo de Blas. Busque un ejemplo similar y encontre que el angulo de Blas es 60° y el de Raul es 45°. Suponiendo que ambos midieron el angulo desde el suelo:
tangente 60° = altura / (41 - d)
tangente 45° = altura / d
altura = (41 - d) · tangente 60° = (41 - d) · 1.73205
altura = d · tangente 45° = d · 1
d = 71.01408 - 1.73205d
2.73205d = 71.01408
d = 71.01408 / 2.73205 = 25.993 ≈ 26 metros
sustituimos:
altura = d · tangente 45° = 26 · 1 = 26 metros
La altura del generador es de 26 metros
