Answer:

B) 54π in²

Step-by-step explanation:

area of full circle = πr² = 81π in²

area of 4π/3 segment = (81)(4π/3)/2π = 54π in²

Given:

Bases of the trapezoid are 5.2 m and 14.6 m.

The height of the trapezoid is 7 m.

To find:

The area of the trapezoid.

Solution:

The area of a trapezoid is:

[tex]A=\dfrac{a+b}{2}\times h[/tex]

Where, a,b are bases and h is the height of the trapezoid.

Putting [tex]a=5.2,b=14.6,h=7[/tex] in the above formula, we get

[tex]A=\dfrac{5.2+14.6}{2}\times 7[/tex]

[tex]A=\dfrac{19.8}{2}\times 7[/tex]

[tex]A=9.9\times 7[/tex]

[tex]A=69.3[/tex]

Therefore, the area of the trapezoid is 69.3 square meters.

Answer:

y = -1/2 x + 2

Step-by-step explanation:

Which of the following equations describes the line shown below? Check all

that apply.

(-4, 4)

(2, 1)

The standard equation of a line is y = mx,+b

m is the slope

b is he y-inttercept

Get the slope

Slope m = y2-y1/x2-x1

Substitute the coordinate

M = 1-4/2-(-4)

M = -3/6

M = -1/2

Substitute m= -1/2 and (2,1) into y = mx+b

1 = -1/2(2)+b

1 = -1+b

b = 1+1

b=2

Get the equation

Recall y =mx+b

y = -1/2 x + 2

Step-by-step explanation:

Half of 12 is 6, a third of 18 is 6, a sixth of 36 is 6, but a fourth of 20 is only 5. So it does not belong.

Answer:

Hello! r would equal 0.4. To do this, first subtract 4 from both sides. So (10r+4-4=8-4). You are then left with 10r=4. So then you divide both sides by 10. 10r/10=4/10. So you are left with 0.4. r=0.4

Step-by-step explanation:

The probability of getting prime number is 2/7.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Outcome = 4, 5, 6, 6, 7, 8, 9.

Number of outcome = 7.

a) The prime numbers from the outcome are 5 and 7.

So, the probability of getting prime number

= 2/7

Hence, the probability is 2/7.

Answer:

Bella do you know the distance formula?  that's the "tool" you need for these questions.  :)  Answers are bolded below  :)

Step-by-step explanation:

dist = sqrt[ x2-x1)^2 +(y2-y1)^2]

Robins house is at Point P1 = (-9,10)  in the form (x1,y1)

Sarah's house is at Point P2=(3,5) in the form (x2,y2)

dist from Robin's to Sarah's is

dist_RS = sqrt[ (3-(-9))^2 +(5-10)^2]

dist_RS = sqrt[ (3+9)^2 + (-5)^2]

dist_RS = sqrt[ 12^2 + 25 ]

dist_RS = sqrt [ 144+25]

dist_RS = sqrt [ 169]

dist_RS = 13

distance from Robin's to Jada's  

where Jada's house is at Point P3 =(-3,2) in the form (x3,y3) (we can think of this as P2 in the form (x2,y2) in our formula)

dist_R J= sqrt [ (-3-(-9))^2 + (2-10)^2 ]

dist_R J= sqrt [ (-3+9)^2 + (-8)^2 ]

dist_R J= sqrt [ (6)^2 + 64 ]

dist_R J= sqrt [ 36 + 64]

dist_R J= sqrt [ 100 ]

dist_R J= 10

distance to Madison's house

where Madison's house is at Point P4 = (-1,-5) in the form (x2,y2)

dist_RM = sqrt [ (-1-(-9))^2 + (-5-10)^2 ]

dist_RM = sqrt [ (-1+9)^2 + (-15)^2 ]

dist_RM = sqrt [8^2 + 225 ]

dist_RM = sqrt [ 64 + 225 ]

dist_RM = sqrt [289 ]

dist_RM = 17

Jada's house is 10 , Madison's is 17 so it's 7 miles farther to Madison's than to Jada's

Step-by-step explanation:

I hope this helps. have a great dsy

Answer:

perimeter of a rectangle = 2( l+b )

perimeter = 60 inches

length = 22 inches

∴ width =

2 ( 22 + b ) = 60

22 + b = 60/2 = 30

22 + b = 30

b = 30 - 22 = 8 inches

∴ width = 8 inches

Answer:

Purchase rate of the house is $480000.

Step-by-step explanation:

Let the purchase rate of the house = $p

Current value of the house = $648000

If the current rate of the house has increased by 35% of the purchase rate,

Current rate = Purchase rate +  35% of the purchase rate

648000 = p + (35% of p)

648000 = p + [tex]p\times \frac{35}{100}[/tex]

648000 = p + 0.35p

648000 = (1.35)p

p = [tex]\frac{648000}{1.35}[/tex]

p = $480000

Therefore, purchase rate of the house is $480000.

Answer:

9 cm²

Step-by-step explanation:

Two wires are attached 6 feet up a tree and 3 feet from the base of the tree. About how much TOTAL wire was used?

We solve the above question, using the Area of a Triangle

Area = 1/2 × Base × Height

Area = 1/2 × 3 × 6

Area = 9 cm²

Therefore, the total wore that was used was 9cm² of wire

5 turning points are in the graph of the polynomial function.

Turning points occur when a graph shifts from rising to dropping (rising to falling) or from decreasing to increasing (falling to rising). A polynomial of degree n can turn at most once, or n1.

The point on a parabola where the graph shifts from increasing to decreasing, or from decreasing to increasing, is known as the turning point of a parabola and is also known as the vertex. We refer to a graph as growing when it is rising from left to right.

Turning points are places on a graph where the direction of the line switches from upward to downward.

And from below to above.

We can see that graph is changing its direction at  5 different points and the points are

(-5,6) ,(-3,-3) ,(0.5,0.5) ,(3,2.5) ,(5,5)

Thus, there are 5 turning points.
