A circle has a diameter of 18
m. Find the area of the sector
whose central angle is 135º

9514 1404 393

Answer:

  215.6 cm^2

Step-by-step explanation:

The top and bottom "wings" are 3.25 cm by 12.25 cm, so each has an area of ...

  A = LW

  A = (12.25 cm)(3.25 cm) = 39.8125 cm^2

The left and right "wings" are 3.25 cm by 7.25 cm, so each has an area of ...

  A = (7.25 cm)(3.25 cm) = 23.5625 cm^2

The middle rectangle is 12.25 cm by 7.25 cm, so its area is ...

  A = (12.25 cm)(7.25 cm) = 88.8125 cm^2

Then the total area is ...

  area = middle rectangle + 2×side wings + 2×top/bottom wings

  = 88.8125 +2(23.5625) +2(39.8125) = 215.5625 . . . cm^2

The area of the figure is about 215.6 cm^2.

Answer:

33% or 33.3% or 33.33%

Step-by-step explanation:

1/3 as a decimal is 1 divided by 3 which ends up being an infinite number: 0.33333333333333333333333...

But you can write it as 33% or 33.3% or 33.33%

Answer:

[tex]x=1,CD=5[/tex]

Step-by-step explanation:

It's given that [tex]ABCD\cong FGHJ[/tex]. Because the side [tex]CD[/tex] corresponds with the side [tex]HJ[/tex], their lengths will be equal. Therefore, we have:

[tex]2x+3=3x+2,\\x=1[/tex]

Plugging [tex]x=1[/tex], we have:

[tex]CD=2(1)+3=5[/tex].

Answer:

2 oranges

Step-by-step explanation:

Two halves make a whole orange, and since there's four of them, they are eating 2 oranges.

Answer:they would have eaten 2 because 1/2+1/2 is a whole and since there are 4 boys eating 1/2 of an orange they would have eaten 2 oranges

Answer:

for the volume of the sphere its answer is 4πr³/3 which when converted to diameter will be 2(4πr³/3) as r=diameter/2 so diameter =2r

Answer:

4πr³/3

Step-by-step explanation:

When converted to diameter will be 2(4πr³/3) as r=diameter/2 so diameter =2r

Answer:

D

Step-by-step explanation:

plug in both values into the equations, and whichever one works for both is the right answer

the required equation is, D. y= x+6

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (-2,4) and, (2,8)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>(y-4)/(x+2)=(8-4)/(2+2)

=>y-4=x+2

=>y=x+6

Hence, the required equation is, D. y= x+6

Answer:

19.6 Don't ask how just give brainliest

Answer:

19.6

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

rules:

add outside the function : f(x) ± a;  will shift  a + up / a- down

add inside the function: f(x ± a); will shift a + left  / a- right

so if

f(x)  becomes f(x) -4  will be shifting down 4 units

Step-by-step explanation:

The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

So the smallest angle is <P.

Answer:

12 miles

Step-by-step explanation:

sometimes looking at the units is helpful.

How far Tristan will walk is measured in miles.

3 miles/hour * 4 hours has a unit of miles * hour/hour = miles

3*4 = 12

Answer:

12 Miles

Step-by-step explanation:

Multiply 3 by 4

Step-by-step explanation:

since b = 8, it has to be

y = 2x + 8

that was the whole point of the exercise, as the general slope-intercept form is

y = mx + b

you determined m = 2 and b = 8, so there is your answer. I am not sure where your problem was, as you solved the actual important part yourself.

Answer:

D. 4 (5 + 16)

Step-by-step explanation:

20 + 64 = 84

To solve this problem we have to simplify each of the expressions in the answer column:

A. = 80

(16 + 60 = 76) giving us

4 + 76 = 80

B. = 25

(5 + 16 = 21)

4 + 21 = 25

C. = 80

(16 + 60 = 76)

4 + 76 = 80

D. = 84

(5 + 16 = 21)

4 x 21 = 84

So The correct option is D. 4 (5 + 16)

Answer:

a=9

b=11

Step-by-step explanation:

opposite sides of a parallelogram are congruent(aka equal)

so, a=9

b=11

Answer:

A is 9 units and B is 11 units.

Step-by-step explanation:

In a parallelogram, there are 2 parallel line. And they are congruent. So whatever their parallel line is equal to, it is the measure of that variable.

Answer:

None of these

Step-by-step explanation:

because if we plug in every time we will gwt one solution of X

Step-by-step explanation:

Given that the ratio of zebras are 5 and giraffes are 2

We add them giving is 7

So: giraffe=2/7 × 21 = 6

Zebra 5/7 × 21 = 15

Answer:

c = 6.1

Step-by-step explanation:

Given that: B = 18° , C = 152°,  and b = 4.

The missing side, c, can be determined by applying the sine rule which states that:

[tex]\frac{b}{Sin B}[/tex] = [tex]\frac{c}{Sin C}[/tex]

[tex]\frac{4}{Sin 18^{o} }[/tex] = [tex]\frac{c}{Sin 152^{o} }[/tex]

c = [tex]\frac{4* Sin 152^{o} }{Sin 18^{o} }[/tex]

 = [tex]\frac{1.8779}{0.3090}[/tex]

 = 6.0773

c = 6.1

Therefore,  the value of the missing side, c, is 6.1

=======================================================

Explanation:

VX is a midsegment and it is half as long compared to the parallel side UY. This means UY is twice as long compared to VX

UY = 2*(VX)

s = 2*(s-37)

s = 2s - 74

s-2s = -74

-s = -74

s = 74

This makes UY be 74 units long

So VX = (1/2)*UY = 0.5*74 = 37

Answer:

37

Step-by-step explanation:

The midsegment theorem states that a midsegment is half the measure of the line it is parallel to (the base).  So VX is 1/2 of UY. So:

2(s-37)=s

2s-74=s

s=74

VX= 37

Answer:

The answer is (-8/5,32) in point form or x=-8/5,y=32

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

[tex]y = 25x +1950[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (30,2700)[/tex]

[tex](x_2,y_2) = (50,3200)[/tex]

Required

Determine the linear function

We start by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{3200 - 2700}{50 - 30}[/tex]

[tex]m = \frac{500}{20}[/tex]

[tex]m = 25[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 2700 = 25(x - 30)[/tex]

[tex]y - 2700 = 25x - 750[/tex]

Make y the subject

[tex]y = 25x - 750 + 2700[/tex]

[tex]y = 25x +1950[/tex]

Given:

The expression is

[tex](7-\sqrt{7})(-6+\sqrt{7})[/tex]

To find:

The product of the radical expression.

Solution:

We have,

[tex](7-\sqrt{7})(-6+\sqrt{7})[/tex]

Using distributive propertry, we get

[tex]=(7)(-6)+(7)(\sqrt{7})+(-\sqrt{7})(-6)+(-\sqrt{7})(\sqrt{7})[/tex]

[tex]=-42+7\sqrt{7}+6\sqrt{7}-7[/tex]

On combining like term, we get

[tex]=(-42+7)+(7\sqrt{7}+6\sqrt{7})[/tex]

[tex]=-49+13\sqrt{7}[/tex]

Therefore, the product of the given radical expression is [tex]-49+13\sqrt{7}[/tex].
