A trapezoid has a base of 12 inches and 50
inches. The height of the trapezoid is 21
inches. What is the area of the trapezoid?
Answer:
Step-by-step explanation:
Givens
b1 = 12
b2 = 50
h = 21
Area = ?
Equation
Area = (b1 + b2) * h / 2
Solution
Area = (12 + 50) * 21 / 2
Area = 62 * 21 / 2
Area = 31 * 21
Area = 651

Linda bought $87.95 worth of merchandise at an electronics store. She
returned a video game and received a refund of $27.79. Linda also had to
pay a restocking fee of $6.17 for the returned game. After returning the
video game, what was the total cost of Linda's purchase?
Answer: She paid $66.33
Step-by-step explanation:
The overall amount that you paid for the video game was 87.95. She got 27.79 back as a refund. So you subtract what she paid from her refund. 87.95-27.79 = 60.16. She also had to pay a fine for the video game. So you add the fine to the amount. 60.16+6.17 = 66.33.
Overall, she paid 66.33.
Answer:
It's $66.33
Step-by-step explanation:
87.95-27.79+6.17=66.33
↓
She first bought electronics worth of $87.95.
Returned a video game and received a refund of $27.79.
=60.16 (87.95-27.79) | You have to subtract.
Had to pay a fee of $6.17 after returning the video game.
final amount - $66.33 (60.16+6.17) | You have to add the amount she now had after she got the refund and the restocking fee she had to pay.

Points S, U, and T are the midpoints of the sides of TrianglePQR. Triangle S U T is inside of triangle P Q R. Points S, U, and T are the midpoints of triangle P Q R. Which statements are correct? Check all that apply.
Answer:
1/2 QP = UT
SU ║ RP
Step-by-step explanation:
If UT is parallel to QP, then it is half the length of QP. ΔTUR ~ ΔPQR with a scale factor of 1/2.
It T is the midpoint of PR, then SU is parallel to RP and half its length. Again, ΔQSU ~ ΔQPR with a scale factor of 1/2.

Lydia was doing her homework. She did math for 3/5 of an hour. She did science for 2/3 of an hour, half an hour for art sketches, and 1/10 of an hour for French. and How much time did she spend on her homework? How much time would she have spent if she took 10 minutes break between each subject? Show your work.
Answer:
82 minutes
102 minutes with breaks
Step-by-step explanation:
So there are 60 minutes in an hour. 3/5 of 60 is 36. 2/3 of 60 is 40. And 1/10 of 60 is 6. So adding all those numbers up 36+40+6=82 minutes.
Now if she spent 10 minute breaks in between her assignments then she did 36+10+40+10+6=102 minutes with breaks in between Math and Art also Art and French

Samantha is constructing a door frame with base 30 inches, height 84 inches, and diagonal 91 inches. A sketch of the door frame is shown.
Answer:
The door is not in rectangle shape.
Step-by-step explanation:
Given:
Length of base = 30 inches
Height of door = 84 inches
Diagonal of door = 91 inches
Find:
The door is rectangle or not
Computation:
Using Pythagorean theorem
Hypotenuse² = Perpendicular² + Base²
So,
91² = 84² + 30²
8,281 = 7,056 + 900
8,281 ≠ 7,956
So we say that the given door angle is not 90°
So,
The door is not in rectangle shape.

The question is incomplete. The complete question is :
Martin drew a triangle. Its sides were 3\text{ cm}3 cm3, start text, space, c, m, end text, 4\text{ cm}4 cm4, start text, space, c, m, end text, and 5\text{ cm}5 cm5, start text, space, c, m, end text. It has one right angle and two acute angles. Complete the sentence to describe the triangle Martin drew. Martin's triangle ......
Solution :
A triangle is defined as a close figure with three sides. It is polygon having three angles. If one of the angle is a right angle, then that triangle is known as a right angled triangle.
By Pythagoras theorem, the line opposite to the right angle is called as hypotenuse and it is the longest side in a right angled triangle.
Let a and b be the other sides and let c be the hypotenuse.
So by Pythagoras theorem, we get that [tex]$c^2=a^2+b^2 $[/tex]
From the question, a = 3 cm
b = 4 cm
c = 5 cm
Therefore,
[tex]$5^2=3^2+4^2$[/tex]
25 = 9 + 16
25 = 25
Thus the triangle is a right angled triangle.

Answer:
3.24 m²156 cm²Step-by-step explanation:
1.
Area of a parallelogram = base × height
The area of the parallelogram
= 2.7 × 1.2
= 3.24 m²
2.
Try to divide the figure into 2 rectangles and find their areas.
The area of the larger rectangle
= 6 × (20-6)
= 84 cm²
The area of the smaller rectangle
= 12 × 6
= 72 cm²
The total area of the figure
= 84 + 72
= 156 cm²
Answer:
C) 3.24m^2
C) 156 cm^2
Step-by-step explanation:
The area of a parallelogram is base * height.
The base is 2.7m, while the height is 1.2m.
2.7*1.2 = 3.24m^2.
We can envision the area of the figure to be a rectangle with another rectangle cut out of it.
The total rectangle's area is 20*12, which equals 240cm^2.
The smaller rectangle's width would be 12 - 6, which is 6. The length would be 20 - 6, which is 14. 6 * 14 = 84.
Now we just have to subtract 84. from 240, which is simple. 240-84=156.
The answer is 156cm^2.

Find the area of the following figures:
Answer:
The area of the following figure is 400 [tex]m^2[/tex].
Step-by-step explanation:
On the left side of the figure, you'll see that there is a half-circle with a diameter of 20 meters. On the right side of the figure, there is a gap for a half-circle with a diameter of 20 meters. To make the calculation process easier, you can imagine that you take the half-circle from the left side and fit it onto the gap on the right in order to form a 20 meters by 20 meters square. Now you can just multiply the side lengths together to find the area, which will be 20 * 20 = 400 [tex]m^2[/tex].

In one weekend, 1,200 people attend a play at the theater downtown. A survey of 100 people who attended found that 45 gave the play at least 4 stars out of 5. Use the indicated method to estimate how many people in all would give the play at least 4 stars.
Answer:
540
Step-by-step explanation:
fraction of those surveyed that gave the play at least four stars = 45 / 100 = 0.45
Estimate of people who would rate the play at least four stars = 0.45 x 1200 = 540

(Polynomials)Expand: (m/2+2n)^3
Answer: m^3/8+3m^2n/2+6mn^2+8n^3 Hope that helps!
Step-by-step explanation:
1. Use cube of sum : (a+b)^3=a^3+3a^2b+3ab^2+b^3
(m/2+2n) ((m/2)^2+2×m/2×2n+(2n)^2)
2. Use division distributive property: (x/y)^a= x^a/y^a
(m/2+2n)(m^2/2^2+2×m/2×2n+(2n)^2)
3. Simplify 2^2=4
(m/2+2n)(m^2/4+2×m/2×2n+(2n)^2)
4. Use multiplication distributive property (xy)^a= x^a y^a
(m/2+2n)(m^2/4+2×m/2×2n+2^2n^2)
5. Simplify 2^2=4
(m/2+2n)(m^2/4+2×m/2×2n+4n^2)
6. Cancel 2
(m/2+2n)(m^2/4+m×2n+4n^2)
7. Regroup terms
(m/2+2n)(m^2/4+2mn+4n^2)
8. Expand by distributing sum groups
m/2(m^2/4+2mn+4n^2)+2n(m^2/4+2mn+4n^2)
9. Expand by distributing terms
m^3/8+m^2n+2mn^2+2n(m^2/4+2mn+4n^2)
10. Expand by distributing terms
m^3/8+m^2n+2mn^2+nm^2/2+4n^2m+8n^3
11. Collect like terms
m^3/8+(m^2n+m^2n/2)+(2mn^2+4mn^2)+8n^3
12. Simplify.
And your answer would be m^3/8+3m^2n/2+6mn^2+8n^3
