Answer:
129.3 in²
Step-by-step explanation:
The shaded segment is calculated as
area of sector ABC - area of triangle ABC
area of sector = area of circle × fraction of circle
A = πr² × [tex]\frac{60}{360}[/tex]
= π × 18² × [tex]\frac{1}{6}[/tex]
= 324π × [tex]\frac{1}{6}[/tex] = 54π in²
area of Δ ABC = [tex]\frac{1}{2}[/tex] × 18 × 18 × sin60° ≈ 40.30 in²
Then
shaded area = 54π - 40.30 ≈ 129.3 in² ( to the nearest tenth )

Answer:
What is the length of EF: 12
What is the length of BC: 8
Step-by-step explanation:
Since there congruent shapes the line segments are gonna be the same lengths.
Answer:
Step-by-step explanation:
If the figures are congruent then BA and FE are equal. You only know this by the shape.
EF = 12BC = 8Both are corresponding parts of equal triangles.Express the polynomial that is twice the sum of 4x2 - x + 1 and -6x2 + x - 4.
Answer: -4x-6

find An Equation Of The Line Containg(3,-4) and Having slope -2.If This Line Contain The Points (a,8) and (5,b) find a and b
Answer:
equation: y=-2x+2
a=-3
b=-8
Step-by-step explanation:
we need to find the equation of the line containing the point (3,-4) and has the slope (m) of -2
slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
we can plug what we know into the equation:
y=-2x+b
we need to find b though
since the point will pass through the point (3,-4) we can subsitute it into the equation to find b
-4=-2(3)+b
-4=-6+b
2=b
the y intercept is 2
so the equation is y=-2x+2
the line also contains the points (a,8) and (5,b)
first, let's find a
a is the x value of the point
we know the value of y (8)
substitute y as 8 and solve for x
8=-2x+2
subtract
6=-2x
-3=x=a
so a is -3
now find b
b is the y value of the point
we know the x value (5)
substitute x as 5 and solve for y
y=-2(5)+2
y=-10+2
y=-8=b
so b is -8
hope this helps!

Give me a hand please! Triangle VZX is similar to RPQ where ZX corresponds to PQ. If VZ = 8 cm, ZX = 6.4 cm, VX = 11.2 cm, and PQ = 5.12 cm, what is the measure of RQ?
A) 4.096 cm
B) 10 cm
C) 8.96 cm
D) 6.4 cm
Answer:
C: 8.96
Step-by-step explanation:
We know taht ZX is similar to PQ. We can now set up the ratio of 6.4: 5.12
This ratio gives us .8:1
Multiply VX by the ratio to find its corresponding similar side of RQ
(11.2) * .8 = 8.96

A teacher took a survey of his eight class. After Finishing his survey, he found that there was no correlation between the number of miles the students live from school and the students grades. Which graph can represent the result of the survey?
Answer:
The graph in the middle with points all around the place would be the answer.
Step-by-step explanation:
The result of the survey showed no correlation, so there would be no pattern or trend line in the graph. So it cannot be the 1st graph or the 3rd.

Read the problem. 10% of the students at Harris Middle School are on the yearbook committee. If 30 students are on the yearbook committee, how many students are at Harris Middle School? Pick the model that represents the problem. How many students are at Harris Middle School?
Answer:
100%
300 students
Step-by-step explanation:
let b = number of students in the school
this equation can be derived = 10% x b = 30
to find b, divide both sides of the equation by 10%
b = 30/0.1 = 300
we want find the total number of students in the school, which is equal to 100%

If y=−3, then
4y
4+y
=
Answer:
if Y=-3 and 4y is the equation then the answer is -27
Answer:
4y=-12
4+y=1
Step-by-step explanation:
when y=-3
then you substitute the value of y into the questions
4(-3)=
4×-3
=-12
4+y
4+(-3)
we know that plus(+) multiplied by(×) minus(-) is equal to(=) minus(-)
so therefore,
4-3
=1
A large pizza has a diameter of 14 inches. A medium pizza has a diameter of 10 inches. How much larger is the area of the large pizza than the area of the medium pizza. Round your answer to the nearest hundredth place. ** Use 3.14
A. 12.56
B. 50.24
C. 75.36
D. 78.50
Answer:
The bigger pizza has a diameter of 14 inches, or a radius of 14 / 2 = 7 inches.
The smaller pizza has a diameter of 12 inches, or a radius of 12 / 2 = 6 inches.
Step-by-step explanation:
The area of a circle is πR2 where R is the radius.
The difference in the size of the pizzas is
Area of bigger pizza - Area of smaller pizza
= π(7 inches)2 - π(6 inches)2 = = 49π inches2 - 36π inches2 = 13π inches2
The area of the large pizza is 13π inches² larger than the area of the medium pizza.
The bigger pizza has a diameter of 14 inches,
a radius = 14 / 2 = 7 inches.
The smaller pizza has a diameter of 12 inches.
radius = 12 / 2 = 6 inches.
What is the area of the circle?The area of the circle is defined as the product of the pie and the square of the radius.
The area of the circle =πR²
The area of a circle is πR², where R is the radius.
The difference in the size of the pizzas = Area of bigger pizza - Area of smaller pizza
= π(7 inches)² - π(6 inches)²
= 49π inches² - 36π inches²
= 13π inches²

The height of the red triangle is 1/2 the top or bottom white triangle. That's because the diagonals and the horizontal line all meet in the middle.
The base of the red triangle is equal to 1/2 the length of the base.
Formula
Area red = 1/2 b * h
Solution
b = 1/2
h = 1/2
Area = 1/2 * 1/2 * 1/2
Area = 1/8

The circumference of a circle is 9.45cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.
Answer:
D = 3 cm
Step-by-step explanation:
Given that,
The circumference of a circle is 9.45cm.
We need to find the length of the diameter.
The formula for the circumference of a circle is given by :
[tex]C=2\pi r[/tex]
We know that, Diameter = 2r
So,
[tex]C=D\pi\\\\D=\dfrac{C}{\pi}\\\\D=\dfrac{9.45}{\pi}\\\\D=3\ cm[/tex]
So, the length of diameter is equal to 3 cm.
