Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64
Answer:
The solutions are:
[tex]m=-3,\:m=-19[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(m\:+11\right)^2=\:64[/tex]
[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
solving
[tex]m+11=\sqrt{64}[/tex]
[tex]m+11=\sqrt{8^2}[/tex]
[tex]m+11=8[/tex] ∵ [tex]\sqrt{8^2}=8[/tex]
Subtract 11 from both sides
[tex]m+11-11=8-11[/tex]
Simplify
[tex]m=-3[/tex]
now solving
[tex]m+11=-\sqrt{64}[/tex]
[tex]m+11=-\sqrt{8^2}[/tex]
[tex]m+11=-8[/tex] ∵ [tex]\sqrt{8^2}=8[/tex]
Subtract 11 from both sides
[tex]m+11-11=-8-11[/tex]
Simplify
[tex]m=-19[/tex]
Thus, the solutions are:
[tex]m=-3,\:m=-19[/tex]

The value of x is 42 of three parallel lines intersected by two transversal lines
To solve for x in the given scenario of three parallel lines intersected by two transversal lines, we'll first determine the relationship between the corresponding angles.
According to the properties of parallel lines, corresponding angles are congruent. Thus, if we have an equation involving the corresponding angles, we can solve for x.
In this case, we have the equation:
x/35 = 30/25
To solve for x, we can cross-multiply:
25x = 30 * 35
25x = 1050
Dividing both sides by 25:
x = 1050/25
x = 42
Therefore, in the given scenario, the value of x is 42.

Answer: a) one central angle is QPR
b) arc QTS is a semicircle
c) arc QR is a major arc
d) arc QTR = 235
e) arc QR = 125
Step-by-step explanation:
A central angle is an angle with its vertex as the midpoint of the circle.
A semicircle is half of a circle. Segment QS goes through the midpoint P splitting the circle in half : arc QTS and arc QRS are both semicircles.
The degree of a central angle is equal to the arc it encompasses. Central angle QPR is equal to 125, therefore arc QR is equal to 125 as well.
Given this information we can now find the remaining arc QTR. A circle is equal to 360 degrees. We know part of the circle is 125 degrees which means the remaking portion must be 235 degrees.
360 - 125 = 235

What is the difference in height between an albatross flying at 100 m above the surface of the ocean and a shark swimming 30 m below the surface?
Answer: 130 meters
Step-by-step explanation:
We have to let the "surface of the ocean" be at 0 height.
So,
anything above surface has POSITIVE height
and anything below surface has NEGATIVE height
The albatross is 100 m above, so we can say its height is:
+100 meters
The shark is 30 m below, so we can say its height is:
-30 meters
The difference in height is thus:
100 - (-30) = 100 + 30 = 130 meters

101+ 6x-5=180
6x=84
x=14
hope this helps!
Answer:
x = 14
Step-by-step explanation:
Since m || n, the two adjacent angles (101° and (6x-5)) must add up to 180°.
180° - 101° = 79°. Therefore, 6x - 5 = 79.
Add 5 to both sides, and the equation is 6x = 84.
Then divide both sides by 6 to get x = 14.

Angle MNO measures 112°. What is the measure of angle LMN?
34°

Answer:
68°
Step-by-step explanation:
A complete angle is 180 degrees, if MNO is 112 degrees, then you will subtract the two numbers to find the angle measure for LMN
180 - 112 = 68
The value of the angle LMN is [tex]68^{0}[/tex]
What is rhombus?A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. Moreover, all the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles. The rhombus is also called a diamond or rhombus diamond.
It is given that a rhombus LMNO with one angle MNO measures [tex]112^{0}[/tex].
We need to determine the value of the angle LMN.
Now, we know that the sum of the corresponding angles in the rhombus is always equals to [tex]180^{0}[/tex].
Therefore, angle MNO and angle LMN are the corresponding angles of the rhombus LMNO.
Thus,
Angle MNO + Angle LMN = [tex]180^{0}[/tex]
[tex]112^{0}+Angle LMN = 180^{0}[/tex]
Angle LMN = [tex]180^{0} -112^{0}[/tex]
Angle LMN = [tex]68^{0}[/tex]
Hence, the value of the angle LMN is [tex]68^{0}[/tex].

Mr. Ailey gave his class 45 minutes to read. Davida reads 27 3/4 pages in that time. At what rate, in pages per hour, did Davida read?
A 42
B 36
C 34
D 37
Answer:
37 pages per hour
Step-by-step explanation:
Given that :
Time Given to read = 45 minutes ; 45 / 60 = 0.75
Number of pages readable ad by Davida within the given time frame = 27 3/4 pages
David's reading rate in pages per hour :
Number of pages read / time taken (hrs)
[27 3/4] ÷ (45/60)
[111 / 4] ÷ (45/60)
(111 / 4 ) * (60/45)
(111 * 60) / (4 * 45)
6660 / 180
= 37 pages per hour
