Answer:

A = 84 [tex]ft^{3}[/tex]

Step-by-step explanation:

To find the area of a trapezoid, use this equation:

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

a = top base

b = bottom base

h = height

Let's classify all the sides:

a = 4 ft

b = 10 ft

h = 12 ft

Now, let's plug all these into the equation:

[tex]A = \frac{4+10}{2} (12)[/tex]

[tex]A = \frac{14}{2}(12)[/tex]                                    Add what's in the numerator

[tex]A = 7(12)[/tex]                                      Divide 14 by 2

A = 84 [tex]ft^{3}[/tex]                                     Multiply 7 by 12

So, the area of the trapezoid is 84 [tex]ft^{3}[/tex].

Hope this helps!!

Answer:

well, a supplementary angle is two angles that sum up to 180 degrees. If one angle is 8, then the other angle would be found by using 180-8=? Or ?+8=180. Because of this, the other angle would equal 172

Answer: zoe's question's data would vary because not everyone in her class could play video games for the exact same amount of time.

however this is not a statistical question because we do not know when the students are playing video game for example we wouldnt know if she wanted to know how much time a classmates spends playing video games each year, each month, each week, etc. so to make this a statistical question zoe would have to ask....  which student spends the most time a day on video games.

hope this helps ;D

Answer:

The width of the rug is 20 in

The area of the rug is 400 in²

Step-by-step explanation:

Answer:

Width = 20

Area = 400 in[tex]x^{2}[/tex]

Step-by-step explanation:

Width:

half of height

9+31 = 40

40/2 = 20

Area:

First half of kite

A = bh1/2

A = 20*9*1/2

A = 90

Second Half

A = 20*31*1/2

310

310+90

Area of kite is 400 in[tex]x^{2}[/tex]

Answer: No, it isn't.

Step-by-step explanation: This graph shows a Translation, meaning the figure moved. Yes, the rotation of the second figure is 180 degrees, but it was also Translated downwards 2 points down and one to the right.

Yes, ΔP'Q'R' a 180° rotation about the origin of ΔPQR.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Midpoint of PQ: ((2+4)/2, (3+4)/2) = (3, 3.5)

QR: ((4+4)/2, (4+3)/2) = (4, 3.5)

RP: ((4+2)/2, (3+3)/2) = (3, 3)

Translate each midpoint to the origin by subtracting the coordinates of the midpoint from each vertex:

P translated: (2-3, 3-3.5) = (-1, -0.5)

Q translated: (4-4, 4-3.5) = (0, 0.5)

R translated: (4-3, 3-3) = (1, 0)

Rotate each translated vertex by 180° about the origin:

P' rotated: (-(-1), -(-0.5)) = (1, 0.5)

Q' rotated: (-0, -0.5) = (0, -0.5)

R' rotated: (-1, -0) = (1, 0)

Translate each rotated vertex back to its original position by adding the coordinates of the midpoint:

P' translated back: (1+3, 0.5+3.5) = (4, 4)

Q' translated back: (0+4, -0.5+3.5) = (4, 3)

R' translated back: (1+3, 0+3) = (4, 3)

We can see that the coordinates of P', Q', and R' match the coordinates of Q, R, and P respectively

ΔP'Q'R' is a 180° rotation about the origin of ΔPQR.

Hence, yes ΔP'Q'R' a 180° rotation about the origin of ΔPQR.

[tex]\text{According to the condition, circumference,}\\\\~~~~~~~C_1=2\pi r=48~~~~~~~~~~~~~~~~...(i)\\\\\\~~~~~~~C_2 =2\pi \cdot(9r) =18\pi r~~~~~~...(ii)\\\\(ii) \div (i)\\\\~~~~~~\dfrac{C_2}{C_1} = \dfrac{18\pi r}{2\pi r} \\\\\\\implies \dfrac{C_2}{48}= 9\\\\\\\implies C_2 = 48\times 9\\\\\\\implies C_2 = 432~ \text{cm}\\\\\text{Hence, the new circumference is 432 cm.}[/tex]

Answer:

432 cm

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

If the radius is multiplied by 9 then the circumference will also be increased by a factor of 9

given C = 48 cm

then circumference of new circle = 9 × 48 cm = 432 cm

Answer:

The answer is 12.

Step-by-step explanation:

A straight line is 180. Adjacent angles in that line equal 180. Add 10x-20 and 6x+8, which equals 16x-12. Make 16x-12 equal to 180 and add 12. 16x=192, divide both sides by 16 and x=12

Answer:

10 times

Step-by-step explanation:

This is a ratio problem.

We can see from the chart that out of the 36 possible choices, rulling a sum of three is 2. Therefore that fraction would be 2/36, about two times out of the thirty six times rolling would be a three.

Now, they're asking us how many times the sum will be three when the dice are rolled not just 36 times but 180. Therefore we can set up a ratio. We need to do this to find out how many times Tamara can expect to roll a three when she's rolling a total of 180 times.

2/36 = X/180

To solve for X we multiply 180 on each side:

(2/36)(180)=10=X

Therefore, when Tamara rolls the dice 180 times, she can expect the sum to be three 10 times.

Answer:

So, he starts out with $15. Then, Monday - Friday he spends 1.50 every day. (Except Friday.) So then you do 4 days x 1.50 (5 x 1.50 = 6) and that equals 6. Then on Friday, he buys 4 pieces of pizza, and a piece of pizza equals $1.40. So then you do 4 x 1.40, and that equals 5.6. (4 x 1.40 = 5.6) Now you add up 5.6 and 6, and you get 11.6. (5.6 + 6 = 11.6) Then you subtract 11.6 from 15 and you get 3.4! (15 - 11.6 = 3.4)

So, after the week, he has $3.4, so spend on whatever else.

Answer:

C. 56°

Step-by-step explanation:

The measures of a triangle all add up to 180. Since this is a right triangle, we already know one of the measures is 90 degrees. Another measure is given to us, and we need to find measure Q. So far:

mQ = ?

mR = 34°

mS = 90°

To find the remaining angle, just subtract what you already have from the total

180 - (90 + 34) = ?

180 - 124 = 56
