HELP 10 points !!!!!!!
Answer:
B
Step-by-step explanation:
Answer:
84 degrees
Step-by-step explanation:
(6x - 30) + 96 = 180
6x 66= 180
6x= 114
x=19
6(19) - 30 = 114 - 30 = 84
(6x - 30) = 84 degrees

If you have a square with a perimeter of 18 inches, what is the area of the square after
scaling it by 7? Round to the nearest tenth is needed.
Answer:
992.3 in^2 to the nearest tenth.
Step-by-step explanation:
The new perimeter will be 7*18 = 126 inches.
So the side of the new square will be 126/4 = 31.5 inches,
and it's area = 31,5^2
= 992.25
Subtract the shortest length from the longest.
0.81 m
1.08 m
0.8 m
180 cm

There were 7,313 more searches in the library book checkout system in January than February. In February there were 8,972 searches, how many searches were done in both months?
Given:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February.
To find:
The searches in both months.
Solution:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February. So,
Searches in January = 8972 + 7313 = 16285
Now,
Total number of Searches in both months = January + February searches
[tex]=16285 + 8972[/tex]
[tex]=25257[/tex]
Therefore, total number of searches in both months is 25257.

3.05 Quiz: Congruent Polygons and Their Corresponding Parts. Pls help ;-;
Answer:
The correct options are presented as follows;
ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent
Step-by-step explanation:
The coordinate of the preimage point A = (-2, 1)
The coordinate of the image point A' = (2, 1)
Similar for points B(-5, -2) and B'(5, -2), C(-3, -4) and C'(3, -4)
Which is equivalent to a reflection across the y-axis
Similarly, we have;
The coordinate of the preimage point A' = (2, 1)
The coordinate of the image point A'' = (-1, 2)
Which is equivalent to rotation of 90° counterclockwise which involves transforming a preimage (x, y) to an image (-y, x)
Similar for points B and B', C and C'
Therefore, because the reflection transformation, and the rotation transformation, are rigid transformation, the figures of the preimage and the image are congruent
Therefore, we have;
ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent.
-3y+(1)/(5)=(2)/(3)x write in Ax+By=C
Answer:
2/3x + 3y = 1/5
Step-by-step explanation:
-3y + 1/5 = 2/3x (subtract 1/5)
-3y = 2/3x - 1/5 (subtract 2/3x)
-2/3x - 3y = -1/5 (divide by negative 1)
2/3x + 3y = 1/5

a shipping crate is a perfect cube with volume of 2,197 cubic feet. the ceiling of the warehouse is 14 feet high. will the crate fit in the warehouse explain why
answer and i’ll make your brainliest
Answer:
yes it will be able fit through
Step-by-step explanation:
simply divide 2197 and 3 because you need to multiply 3 number to get volume. For this you divide by 3. you should get 732 ft. This is the height. It will be more than enough to fit through
Explain why the exponents cannot be added in the product 12^3 x 11^3?? I need a simple answer that won’t be confusing pls.
Answer:
The bases aren't the same
Step-by-step explanation:
If the bases are the same, then their exponents are added. In this case, since the exponents are the same, then 12^3*11^3=(12*11)^3=132^3=2299968

I need help, -3x+9+4x=10 just wondering if the answer is X=1
Answer:
it's correct good job :)
Answer:
Step-by-step explanation:
Answer: Fortunately, you don’t have to prove that x or y must be 1 or -1 in order for x*y to not be an element of G.
You only need to prove that x*y is an element of G for any x,y in G. (That’s what it means for * to be an operation on G.)
I haven’t thought yet about how to prove that, but let me give you some thoughts off the top of my head.
We know -1 < x, y < 1. We must show -1 < (x + y) / (xy + 1) and (x + y) / (xy + 1) < 1.
First, let’s show that -1 < (x + y) / (xy + 1).
I want to multiply xy + 1 to both sides, but we need to know whether it’s positive or not, so we know whether to reverse the inequality.
Well, -1 < x, y < 1 implies that xy > -1, which implies that xy +1 > 0.
So we must show that -(xy + 1) < x + y.
That is, let’s show that 0 < x + y + xy + 1. (I don’t know if this is going anywhere useful; I’m just playing around with algebra.)

The New England patriots scored 9 points in the first half. In the second half they scored 3 less than 2 times the points in the first half. What is the ratio of of the points and scored in the second half to the total number of points scored
Answer:
[tex]S : T = 5 : 8[/tex]
Step-by-step explanation:
Represent the first half with F and the second with S
We have that:
[tex]F = 9[/tex] --- From the first statement
[tex]S = 2F - 3[/tex] --- From the next statement
Required
Determine the ratio of S to the total point
First, we need to determine the value of S
Substitute 9 for F in [tex]S = 2F - 3[/tex]
[tex]S = 2 * 9 - 3[/tex]
[tex]S = 18 - 3[/tex]
[tex]S = 15[/tex]
Next, we determine the total points
[tex]Total = F + S[/tex]
[tex]Total = 9 + 15[/tex]
[tex]Total = 24[/tex]
The ratio of S to total is: (Represent total with T)
[tex]S : T = 15 : 24[/tex]
Divide both ration by 3
[tex]S : T = 15/3 : 24/3[/tex]
[tex]S : T = 5 : 8[/tex]
Hence, the ratio is 5 to 8

x = 70°
Explanation :
To find : Value of x
Here, given angles are :
35°, 75° and x
Knowledge Required to solve it :
The sum of all the angles of a triangle is 180°.

35°+75°+x=180°
⇒110°+x=180°
⇒x=180°-110°
⇒x=70°
.°. x=70°

Simplify and Distribute
(−5)(4x)+(−5)(−2)=(−2)(3)+(−2)(6x)
−20x+10=−6+−12x
−20x+10=−12x−6
Adding 12x both sides.
−20x+10+12x=−12x−6+12x
−8x+10=−6
Subtract 10 both sides
−8x+10−10=−6−10
-8x = -16
Then divide both sides by 8
-8x/8 = -16/8

Find f (h(-5))
f (x) 9x - 5
g(x) - 3x
h(x) 2x2
Your answer:
hi
You are making f ° h
f(x) = 9x-5
h(x) = 2x²
You must first calculate h(-5) : so remplace x by -5 in h :
h(-5) = 2 (-5)² = 2* 25 = 50
then apply f(x) to result : f(50) = 9 *50 -5 = 450 -5 = 445
