What is the value of x?
x
21.5
13.1
Round your final answer to the nearest tenth.
Use the Pythagorean theorem
Answer
x=37.8
Step-by-step explanation:
According to Pythagoras theorem
AB = 21.5
BC = 13.1
AC = ?
AC²= AB²+BC²
x² =(21.5)²+(13.1)²
x² =462.25+967.21
x² =1429.46
x =√1429.46
x =37.8

A car traveled 281 miles in 4 hours 41 minutes. What was the average speed of the car in miles per hour?
Answer:
64m/h
Step-by-step explanation:
t (time) = d (distance) /v (speed)
t = 281/4.41
t = 63.7

keeping in mind that parallel lines have exactly the same slope, let's check for the slopes hmmm nope, they're not equal, so the lines are not parallel.
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slopes hmmm
[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{1}{4}} ~\hfill \stackrel{reciprocal}{\cfrac{4}{1}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{4}{1}\implies -4}}[/tex]
low and behold, Line 2 has a slope that is negative reciprocal to the slope of Line 1, thus, they're indeed perpendicular.

A cylinder has radius 2.5 meters. its volume is 50pi meters. Find its height.
Answer :
8 meters .⠀
Explanation :
The volume of the cylinder is 50π cubic meters.The cylinder has radius 2.5 meters.⠀
To Find :
The height of the cylinder.⠀
Solution :
⠀
We know,
[tex]{ \longrightarrow\qquad \bf\pi {r}^{2}h = \bf{Volume_{(cylinder) } }}[/tex]
⠀
Where,
r is the radius of the cylinder.h is the height of the cylinder.⠀
Now, Substituting the values :
[tex]{ \longrightarrow\qquad \sf\pi \times {(2.5)}^{2} \times h = {50 \pi } }[/tex]
[tex]{ \longrightarrow\qquad \sf\pi \times 6.25 \times h = {50 \pi } }[/tex]
⠀
Cancelling π from both sides :
[tex]{ \longrightarrow\qquad \sf \cancel\pi \times 6.25 \times h = {50 \: \cancel \pi } }[/tex]
[tex]{ \longrightarrow\qquad \sf 6.25 \times h = {50 } }[/tex]
[tex]{ \longrightarrow\qquad \sf h = { \dfrac{50}{6.25} } }[/tex]
[tex]{ \longrightarrow\qquad {\pmb {\bf{h = {8 } }}}}[/tex]
⠀
Therefore,
The height of the cylinder is 8 meters .HELPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE PLSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

X^2+16x+_=(x+_)^2 what are the missing digits?
Answer:
x^2+16x+64=(x+8)^2
Step-by-step explanation:
For the first spot you find the perfect square of the equation
This is found by doing (1/2 16)^2
1/2 16 = 8
8^2 = 64
The second spot is factoring, where you would put half of 16 or the square root of 64
1/2 16 = 8
root 64 = 8
Use the graph that shows the solution to f(x)=g(x).
f(x)=−(x+2)(x−2)
g(x)=2|x+2|
What is the solution to f(x)=g(x)?
Select each correct answer.
−2
0

4
Answer:
-2, 0
Step-by-step explanation:
The solution(s) to f(x) = g(x) are the x-coordinates of the points where the graphs intersect. The points of intersection of these graphs are ...
(-2, 0) and (0, 4)
The x-coordinates of these points are -2 and 0.
The solutions to f(x) = g(x) are x=-2 and x=0.
Answer:
The answer is -2 and 0

Since the function intersects the x-axis at the point (2,0) & (-4,0), we can then say:[tex]solution = \\ x = 2 \\ x = - 4[/tex]

I do see D(4-1) and C(-3,4). The question asks what is the midpoint. That would be point M, with a coordinate of (0.5,1.5), which is derived from the average of the two points: x: (4-3)/2 = 0.5; y: (-1+4)/2) = 1.5
See the attached image for how the points relate to each other. I derived an equation for the point to illustrate where the midpoint, M, is situated.

Slope = Rise/Run
Rise: (-1 - 4) = -5

If 1 measures 135°, what is the measure of 6? (Lines b and c are parallel.)
65°
45°
135°
90°
Answer:
45 degrees
Step-by-step explanation:
135+135=270
360-270=90
90/2=45
your answer is 45 degrees
Answer:
Step-by-step explanation:
Two angles form linear pair if they are adjacent angles and their non common arms are opposite rays.
Corresponding angles: When two parallel lines are intersected by the transversal, the angles formed on the matching corners of the same side of the transversal are called corresponding angles.
∠1 + ∠2 = 180° {Linear pair}
135 + ∠2 = 180
∠2 = 180 - 135
∠2 = 45°
∠6 = ∠2 {Corresponding angles}
∠6 = 45°

A triangle has an angle measuring 90°, an angle measuring 20°, and a side that is 6 units long. The 6-unit side is in between the 90° and 20° angles.
How many unique triangles can you draw like this?
Answer:
One
Step-by-step explanation:
Since we have a 90° angle and a 20° angle, the last angle must be 70°.
180° - 90° - 20° = 70°
Now we also have the requirement of a 6-unit side between the 90° and 20° angles.
With all of these requirements, we can only draw one triangle like this since we have an angle, an angle, a required third angle, and a side.
Elena drove a total of 203 miles last week. She drove 28 miles during the week to run errands and 35 miles each day to go to work and back. What equation can be used to find the number of days, d, that Elena drove to work last week?
Answer:
ok so the equation will be
35d+28=203
-28
35d=175
divide by 35
d=5
she drove to work 5 times

To find the measure of angle NLM which is x, we must use trigonometry.
In this case we use the sine function:
[tex]sin(x) =[/tex] (side opposite angle NLM) / (hypotenuse)
[tex]sin(x) = \frac{4.9}{7.5} \\x = sin^{-1}(\frac{4.9}{7.5})\\x= 40.8 degrees[/tex]
Hope that helps!
Can someone answer these questions?? Thank you!!!
