A circle has a diameter of 18. The sector has a central angle of 30 degrees. What is the area of the sector?
Answer:
21.21
Step-by-step explanation:
Area of a circle is A = π r^2
Variables:
r = 18/2 = 9
θ = 30 deg
Find the area:
A = π r^2
A = π 9^2
A = 254.47
Find the area of the sector:
θ/360 * A
= 30/360 * 254.47
= 21.21

What is the amount of income tax in dollars and cents if a plumber makes $51,482 and has to pay a 5.5% income tax rate? $2,821.51
Answer:
$2,821.51
Step-by-step explanation:
The amount made be plumber = $51,482
rate of income tax = 5.5%
Therefore, amount of income tax in dollars and cents that would be paid by the plumber would be 5.5% of his amount made
= 5.5% of 51482
= (5.5/100)×51,482
= $2,821.51

Find the area of a regular hexagon with an apothem length of 12.1 and a side length of 14
Answer:
area = 520 units²
Step-by-step explanation:
divide the hexagon into 6 equal triangles.
each triangle has a base of 14 and a height of 12.1 so:
the area of one triangles = 1/2BH = 1/2(14)(12.1) = 86.8 units ²
86.8 x 6 triangles = 520.8 units²

Evaluate the expressions for when x=-1, y=3, z=-2
z²+x²-y and x²y²z²
Step-by-step explanation:
z² +x² - y= -2²+ -1² - 3

x²y²z²= -1²× 3²× -2²
1× 9× 4= 36
Find the intercept and slope in the graph, and find the aquation for the function.
Answer:
Slope = 3
y intercept = -8
y = 3x - 8
Step-by-step explanation:
From the table shown, we can make use of the coordinate points
(0, -8) and (1, -5)
Slope m = y2-y1/x2-x1
m = -5-(-8)/1-0
m = -5+8/1-0
m = 3/1
m = 3
Slope = 3
The standard form of an equation is y = mx+b
b is the y intercept
Substitute m = 3 and (0, -8) into y = mx+b
-8 = 3(0) + b
-8 = b
b = -8
Hence y intercept is -8
Get the required equation
Recall that y = mx+b
y = 3x + (-8)
y = 3x - 8
This gives the required equation

Because pqrs is 4 x 3 and the other side is the same thing
Parallelogram PQRS has diagonals that are perpendicular. Based on that, which statement is most correct?
A- Parallelogram PQRS is also a rectangle
B- Parallelogram PQRS is also a rhombus.
C- Parallelogram PQRS is neither a rectangle nor a rhombus.
D- Parallelogram PQRS is both a rectangle and a rhombus, so it is a square.
Answer:
B- Parallelogram PQRS is also a rhombus.
Step-by-step explanation:
Given
Parallelogram PQRS with perpendicular diagonals
Required
Which of the option is true
(a) PQRS can be a rectangle
A rectangle do not have perpendicular diagonals.
Hence, (a) is false
If (a) is false, then (d) is also false
(b) PQRS can a rhombus
The diagonals of a rhombus are not perpendicular.
So (b) is true
No need to check for (c), since only option is true
Answer:
B- Parallelogram PQRS is also a rhombus.
Step-by-step explanation:

One angle of a triangle measures 57° Which could be the other two angles of the triangle?
A. 48° and 75°
B. 57º and 57°
C. 63º and 70°
D. 70° and 83°
Answer:
A) 48° + 75°
Step-by-step explanation:
All triangles contain 180°
180° - 57° = 123°
A) 48° + 75° = 123°
B) 57° + 57° = 114°
D) 63° + 70° = 133°
A) 70° + 83° = 153°
[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]
The answer is A. 48⁰ and 75⁰
Thr sum of all triangles is 180⁰
so, 180⁰ – 57⁰ = 123⁰
The sum of other two angles should be 123⁰,
so,...
48⁰ + 75⁰ = 123⁰
ThanksHope it helpsPls mark as brainliest.The radius of a circle is 3/4 inches. How many inches is the diameter?
Step-by-step explanation:
Given
In a circle
Radius (r) = 3 / 4 inches
Diameter (d)
= 2 * r
= 2 * 3 /4
= 3 /2 inches
Hope it will help :)❤
The diameter of a circle with a radius of 3/4 inches is 6/4 inches.
We are given that;
The radius of a circle = 3/4 inches
Now,
The diameter of a circle is twice the radius of the circle. Therefore, to find the diameter of a circle with a radius of 3/4 inches, we need to multiply 3/4 by 2. We can do this by multiplying the numerators and the denominators:
(3/4) x 2 = (3 x 2)/(4 x 2) = 6/8
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:
6/8 = (6/2)/(8/2) = 6/4
Therefore, by the circle the answer will be 6/4.

Jesse collects data on his math scores on the last 12 tests and the number of hours he spent completing his math homework assignments and studying in the week before every test. He creates a scatter plot to show the data. The regression line shown on the graph best models the data on the scatter plot.
Based on the given model, how many hours in the week before the test does Jesse need to study to get a score of 90 on the test? Round your answer to the nearest hour.
Answer:
24 hoursStep-by-step explanation:
Using the two points on the regression line, let's find its equation.
Points:
(0, 30) and (8, 50)The slope:
(50 - 30)/8 = 2.5The y-intercept is
30The equation:
y = 2.5x + 30Solve for x if y = 90

A washer and a dryer cost $726 combined. The washer costs $76 more than the dryer. What is the cost of the dryer?
Answer:Cost of dryer=$325
Step-by-step explanation:
Let the dryer be represented as x
and the washer be x+76
such that the price of both can be written as
dryer + washer=$726
x + x+76=726
2x+76=726
2x=726-76
2x=650
x=650/2=325
Cost of dryer =x=$325
