Given:
radius(R) = 12 units
arc = 134°
Find: area of sector
Plan: if you think about it, a sector area is a fractional part of the full area of the circle. It’s a pie piece.
A(circle) = π R^2
134° is 134°/360° = 67/180 That is 67/180 th of the full circle
area (S) = 67/180 (π R^2)
S = 67/180 (π )(12^2) = 67/180(144 π) = 54 π units^2 or
≈ 54(3.1416) ≈ 168.389 units^2
Double Check: ✅ ✅
Answer: 18 π units^2 or 168.39 units^2 approximately
A musician uploads a music video to the Internet and sends a link to the video to 4 friends. Each friend then sends the link to 4 different friends. These 4 friends then send the link to 4 different friends. The musician estimates that about 25% of the people who get the link won't view the video. Complete and evaluate an expression to show how many friends the musician estimates will see the video.
The expression is 43 − (43 ×
).
So, the musician estimates that
people will see the video.

The polygons are similar but not necessarily drown to scale. What is the value of x?
Answer: 38
Step-by-step explanation:
Since the polygons are similar, the corresponding sides are all in the same proportions.
x-2/4.5 = 16/2 = 48/6
Solving for x
[tex]\frac{x-2}{4.5}=\frac{48}{6}[/tex]
[tex]\frac{x-2}{4.5}=8[/tex]
[tex]\frac{4.5\left(x-2\right)}{4.5}=8\cdot \:4.5[/tex]
[tex]x-2=36[/tex]
[tex]x-2+2=36+2[/tex]
[tex]x=38[/tex]
Therefore, the value of x is 38

Answer:
3 minutes 20 seconds
Step-by-step explanation:
Time taken to eat 1/4 of a hamburger = 5/6 minute
The entire burger = 4/4Since 1 x 4 = 4, it will take 4 times the amount of time taken to eat 1/4 of a hamburgerSolving

[tex](x-2)(x-3)^22=0[/tex]
Solve for [tex]x[/tex].
If any individual factor on the left side of the equation is equal to [tex]0[/tex], the entire expression will be equal to [tex]0[/tex].
[tex]x-2=0\\(x+3)^2=0[/tex]
Set the first factor equal to [tex]0[/tex] and solve.
Set the first factor equal to [tex]0[/tex].
[tex]x-2=0[/tex]
Add [tex]2[/tex] to both sides of the equation.

1) A cone with volume 1350 m³ is dilated by a scale factor of 1/3. What is the volume of the resulting cone?
2) The top of the silo is a hemisphere with a radius of 11 ft. The bottom of the silo is a cylinder with a height of 38 ft. How many cubic feet of grain can the silo hold? Use 3.14 for pi and round your answer to the nearest cubic foot.
Answer: The answer is 50 m³.
Step-by-step explanation: We are given to find the volume of the cone cone after being dilated by a factor of one-third from a cone with volume 1350 m³.
The volume of a cone with base radius 'r' units and height 'h' units is given by
[tex]V=\frac{1}{3}\pi r^2h.[/tex]
Therefore, if 'r' is the radius of the base of original cone and 'h' is the height, then we can write
[tex]V=\frac{1}{3}\pi r^2h=1350[/tex]
⇒ [tex]\pi r^2h=4050.[/tex]
Now, if we dilate the cone by a scale factor of , then the radius and height will become one-third of the original one.
Therefore, the volume of the dilated cone will be
[tex]V_d=\frac{1}{3}\pi (\frac{r}{3})^2\frac{h}{3} =\frac{1}{81}[/tex] × [tex]\pi r^2h=\frac{1}{81}[/tex] × [tex]4050=50[/tex]
Thus, the volume of the resulting cone will be 50 m³.

A bucket holding several inches of water was placed under a leaking faucet. Water leaked into the bucket so that the level of the water in the bucket increased by a certain number of inches per hour. The equation y=2x+4 represents this situation, where x is the number of hours and y is the number of inches of water in the bucket. What does the number 4 in the equation represent? A total of 4 inches of water leaked into the bucket. The bucket initially held 4 inches of water. The water level decreased by 4 inches per hour. The water level increased by 4 inches per hour.
The number 4 represents the initially held water of the bucket. Then the correct option is B.

Find the slope of a line that passes through the points (2, 3) and (0, 2).
(slope, 50 points.)
Answer:
1/2
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 2-3)/(0-2)
= -1/-2
= 1/2
Answer:
Slope = 0.5
Step-by-step explanation:
Given: Line passes through (2, 3) and (0, 2)
[tex]\text{Slope formula} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute the coordinates in the formula and solve for the slope;
[tex]\implies \text{Slope formula} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]\implies\text{Slope formula} = \dfrac{2 - 3}{0 - 2}[/tex]
[tex]\implies\text{Slope formula} = \dfrac{-1}{-2}[/tex]
[tex]\implies\text{Slope formula} = \dfrac{1}{2} = 0.5[/tex]
Therefore, the slope of the line is 0.5.

Provide the reflected ordered pair for each of the given ordered pairs.
Answer:
so i have a little trick for you. Reflecting across the x axis is just turning (x,y) to (x, -y)
Reflecting across the y axis is just turning (x, y) to (-x, y)
If we substitute that in we can figure it out
so
(0, 3) we have to turn it to (x, -y), so it would end up being (0, -3). That is the reflection axross the x axis.
(-4,5) we have to turn it to (-x,y) which will be (4,5) because a negative and a negative is positive. so (4,5) is the ordered pair reflected across the y axis! Hope it helps :D
