Answer:
C
Step-by-step explanation:
because angles a is diagonally opposite to 162, they are equal. And as b and 162 are alternate angles, they will also be equal
Answer:
C. <A & <B
Explanation:
If lines m and n are parallel, then you can use the proofs of vertical angles are congruent and alternate interior angles are congruent to prove that <A and <B are equal to 162 degrees; the reason that <C and <D are not congruent, is because they would be too small to fit 162 degrees, they would be the opposite of 162 which is 180-162=18 degrees.

Answer:
y = -5x - 3
Step-by-step explanation:
To answer this the slope must be clculated first
slope equation:
[tex]\frac{y2-y1}{x2-x1}[/tex]
these variables symbolize ordered pairs, and the best part is that you can use any two ordered pairs for this example we can use (-5, 10) and (-3,0)
we'll call the first ordered pair 1 so x1 = -5 and y1 = 10.
the next odered pair is 2 so x2 = -3 and y2 = 0.
With this information layed out we can solve:
[tex]\frac{0-10}{-3-(-5)}[/tex]
0 - 10 = -10
-3 - (-5) = 2 --- remember negatives cancel each other out to make a positive
[tex]\frac{-10}{2}[/tex] = -5
the slope of the line is -5. Now the next thing to note is that one of the ordered pair (-3,0) is a y intercept. It's time to introduce the equatione of a line:
y = mx+b
There are other equations that can be used for a line but with the info given this equation best suits the data.
m = slope
y and x = are the ordered pair you can input into the equation to slove
b = the y intercept
So the equation would be:
y = -5x - 3

Answer: Step 1 is incorrect.
Step-by-step explanation: This is because in the inital equation,
7x + 9 - 2x = 2(x + 15),
there is a distributive property error because they did not multiply both terms in the parenthesis by 2.

b) adjacent and complimentary
c) vertical and supplementary
d) vertical and complimentary
Answer:
b) adjacent and complimentary
Step-by-step explanation:
Supplementary angles equal 180. Complimentary angles equal 90. 55+35 equals 90 and are next to each other therefore they are adjacent and comlimentary.

Answer:
C) None of the above
When you simplify -6+4q+(-6q), you'll end up with -2q-6, which isn't present between the two choices.
-6(q+1)-4q = -10q-6, so that can't be the answer
2(q-3) = 2q - 6. But the 2q isn't negative, so therefore, this isn't the answer either
Therefore, the answer is C: None of the above
Hope this helped!
I can't figure this out
For finding the surface area of the entire cylinder, we need to use the proper formula which is [tex]SA = 2 \pi r h + 2 \pi r^2[/tex]. Since the problem already gives us the radius and height, we can easily plug in the numbers. The equation should now look like this: [tex]SA = 2 * 3.14*3*6 +2*3.14*3^2[/tex].
After multiplying and adding all the numbers in the formula, we get a surface area of 169.56 yards squared.
For the lateral surface area, we can just subtract the [tex]2 \pi r^2[/tex] part from the formula.
[tex]SA = 2 * 3.14* 3 *6[/tex], which is 113.04 yards squared for the lateral surface area.
The question is in the Screenshot so as to answer options.
Answer:
option C

Use the Pythagorean theorem to find the value of b²
So what is the Pythagorean Theorem:
⇒ it states the sum of both leg's lengths squared is equal to
⇒ hypotenuse's length squared
(look at the image attached for a better explanation)
To find out [tex]b^2[/tex], let's look to the Pythagorean equation to see what we are missing:
[tex]a^2 + b^2 = c^2\\(10^2) + b^2 = 325\\b^2 = 325 - 10^2\\b^2 = 325 - 100 = 225\\b^2 = 225[/tex]
a = 10 ⇒ [tex]a^2[/tex] = 100[tex]c^2 = 325[/tex]So b^2 = 225 ⇒ Choice B
Hope that helps!
what is the probability of 0.25
Neither likely? Or nor unlikely?

Ociel has designed a square mural that measures 10 feet on each side. Bill has also designed a square mural, but his measures y feet shorter on each side. How much smaller than Ociel's mural is Bill's mural? Explain.
Answer:
10²- y²
Step-by-step explanation:
Since the mural is 10 feet on one side we can make the size of Ociel's mural just 10². Of course, the same would go for Bill's mural except we square however long one of his sides is. So just subtract Bill's (y²) from Ociel's (10²).
I think that's right... Sorry if I'm wrong the question was just a bit confusing.
answer for brainliest
Step-by-step explanation:
diameterfor first minute :
Circumference = 25.12
2πr = 25.12
22/7 × r = 25.12/2
r = 12.56 × 7 /22
r = 87.92/22
r = 3.99 mm ( approx. )
diameter = 2r = 2 × 3.99 = 7.98 mm
diameter for second minute =
circumference = 75.63
2πr = 75.63
πr = 75.63/2
r = 37.815 × 7/22
r = 264.705/22
r = 12.032 mm
diameter = 2r = 24.064 mm
COMPARISON : 24.064/7.98
3 times greater ( approximately )

Mr. Adams asked two random groups of 20 students each how many minutes they spent playing video games last night. The interquartile range (IQR) for Group A was 30 minutes and the IQR for Group B was 45 minutes. What can you conclude about the data Mr. Adams collected?
A: The maximum is greater for Group B than for Group A.
B: The data for Group B is more spread out than the data for Group A.
C: The maximum is greater for Group A than for Group B.
D:The data for Group A is more spread out than the data for Group B.
Answer:
I think its
Step-by-step explanation:
I think its a because the IQR is the third quartile minus the first quartile (third-first=IQR)(the first is the middle number between the minimum and median and the third quartile is the middle number between the median and the maximum)so anyway it just makes sense that the answer would be B

Answer:
|x - 5| = 2
Step-by-step explanation:
Since we are not given a zero on the number line, we do the following:
Average = midpoint between two numbers on the number line
For this number line,
Average = 3 + 7 ÷ 2
Average = 5
Next we find how many units away are each number from the middle:
3 is 2 units away from 5
7 is 2 units away from 5
Units away = 2
Let's use the formula:
|x - average| = Units away
Substitute values into equation
|x - 5| = 2
Now we solve
Solve for x over the integers:
|x - 5| = 2
Split the equation into two possible equations:
x - 5 = 2 or x - 5 = -2
Add 5 to both sides:
x = -5 + 5 = 2 + 5 or x - 5 + 5 = -2 + 5
Answer:
x = 7 or x = 3
