Answer:
Step-by-step explanation:
so the number is 27 + x which is on ST side so the same side is CD. So we put 27 + x = 30
-27 = -27
----------------------
x = 3
always look at the pattern of the angles like angle DBC ~ TRS and see what its asking for
I'm doing a math test, and I don't understand this question. How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height of 2 1/3 inches?
Answer: 62
Step-by-step explanation:
First and foremost, we have to calculate the volume of the box which will be:
= 2 2/3 × 3 1/3 × 2 1/3
= 8/3 × 10/3 × 7/3
= 560/27
= 20 20/27
The number of 1/3 inch cubes needed to fill the box will then be:
= 20 20/27 ÷ 1/3
= 560/27 ÷ 1/3
= 560/27 × 3
= 560/9
= 62 2/9
Therefore, 62 boxes can be filled
Which expression is equivalent to 12 x + 3 ( x − 2 )
Answer:
15x - 6
Step-by-step explanation:
To solve this, Given the expression 12 x + 3 ( x − 2 )
To simplify, expand
12 x + 3 * x −3 * 2
Knowing that
- * + = -
then the expression becomes
= 12 x + 3x - 6
= 15x - 6
The expression given is equivalent to 15x - 6

HELP!!
If we changed the -3 to a 3 in the equation, what would happen to the graph?
Answer:
It would change the y-intercept, so if it turned into a 3, the slope would just go higher at the beginning.
Step-by-step explanation:
Hope it helps!
The graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The equation y = 2ˣ⁻⁴ - 3 is an exponential function that has been shifted 4 units to the right and 3 units down from the basic exponential function y = 2ˣ.
If we change the -3 to a 3, we get the new equation:
y = 2ˣ⁻⁴ + 3
This new equation represents the original exponential function shifted 4 units to the right and 3 units up.
Therefore, the graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.

Answer:
120
Step-by-step explanation:
all angles of a triangle add up to 180. 180-15-45= 120.
:D
brainliest pls
Given :
Measure of an angle = 15°
Measure of the second angle = 45°
Let the measure of the third angle be x.
We know that :
▪︎Sum of all angles of a triangle = 180°[angle sum property]
Which means :
[tex] =\tt 15 + 45 + x = 180[/tex]
[tex] =\tt 60 + x = 180[/tex]
[tex] =\tt x = 180 - 60[/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 120°[/tex]
Thus, the measure of the third angle = 120°
Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.
Therefore, the correct option is (C) 120

Answer:
D. x = 18 cm , y = 9
Step-by-step explanation:
With reference angle 60
perpendicular (p) = 9[tex]\sqrt{3}[/tex]
base(b)= y
hypotenuse (h) = x
Then
sin 60 = p/h
[tex]\frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{x}[/tex]
x = 18
Now
cos 60 = b/h
1/2 = y/18
y = 9
Hope it will help :)

Step-by-step explanation:
Gavin wants to buy a jacket that sells for $38.95. An advertisement says that next week that jacket will be on sale for $22.50. How much will Gavin save if he waits until next week to buy the jacket?
Answer: Gavin will save $16.45 if he waits until next week to buy the jacket.
Step-by-step explanation:
Given: Current Market price of jacket = $38.95
Sales price next week = $22.50
Amount he can save = (Current Market price of jacket)- (Sales price next week )
i.e. Amount he can save = $ (38.95-22.50)
i.e. Amount he can save = $ 16.45
Hence, Gavin will save $16.45 if he waits until next week to buy the jacket.

Step-by-step explanation:
I THINK im not really used to this but yes this is my expression i would present.
F(x)=3x-2 find f^-1(x) than find f^-1(13)
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 3x - 2 ( add 2 to both sides )
y + 2 = 3x ( divide both sides by 3 )
[tex]\frac{y+2}{3}[/tex] = x
change y back into terms of x with x = [tex]f^{-1}[/tex] (x)
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+2}{3}[/tex]
To evaluate [tex]f^{-1}[/tex] (13) substitute x = 13 into [tex]f^{-1}[/tex] (x) , that is
[tex]f^{-1}[/tex] (13) = [tex]\frac{13+2}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5
