The area of a trapezoid is (a+b) / 2 x h
4 + 8 / 2 = 6
6 x h(2) = 12
Answer:
Step-by-step explanation:
Remark
You need the information from Part A (which is correct). Then you can do Part B.
Givens
shorter base = 4
height = 2
Longer base (b) = 8
Equation
Area = (Shorter Base + Longer Base) * h / 2 Substitute values. Solve
Solution
Area = (4 + 8)*2/2
Area = 12

Jayden wants to lay sod on his front yard and on half of his back yard. His front yard has a length of 50 feet and a width of 70 feet. His back yard has a length of 10 feet and a width of 30 feet. How many square feet of sod does Jayden need to purchase?
Answers
The first thing we must do for this case is to calculate the area of both yards.
We have then:
front yard:
A1 = (50) * (80)
A1 = 4000 feet ^ 2
Back yard:
A2 = (10) * (30)
A2 = 300 feet ^ 2
"Jayden wants to lay sod on his front yard and on half of his back yard"
Then, the total amount will be:
A = A1 + (1/2) A2
Substituting:
A = 4000 + (1/2) (300)
A = 4000 + 150
A = 4150 feet ^ 2
Answer:
jayden needs to purchase 4150 square feet of sodd
Answer:
Its an area equation. Area is length times width.
So to start, he needs 50 x 80 square feet in his front yard, BUT THAT IS ONLY HALF OF THE PROBLEM. For the front yard he needs 4000 sq. feet. For the back, it is different. He needs 10x40÷2. To first simplify, we do the multiplication. This comes to 400÷2. then it is simply 200.
Now for the easy part. Take the 4000 and add 200. Answer? 4,200.
What is the value of x? image below
Answers
Answer:
Angle x = 72
Step-by-step explanation:
Angle AHI = Angle HIK = 63
(This is because the two angles are corresponding angles, HI//JK)
Angle x = 180 - 63 - 45
= 72
A triangle makes 180 degrees total no matter what so if we have two angle measures we can add them and subtract from 180. 63 + 45 = 108. 180-108= 72 degrees :)

you multiplied first 1 times 8 and then divide by 2 in which you will get an answer of 4/8 and to check it you divide 1/2 which gives you 0.5 and then divide 4/8 to see if it is an equivalent fraction and it will give you 0.5 in which yes sir its an equivalent fraction so 4/8 is the correct answer and have a great day.

If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?
Answers
Answer:
40 degrees is (40/360)=0.111=11.1%
The color closest to 11.1% is Purple at 12%.
The total who prefer a rainbow color is:
13+4+5+15+16+12=65
Of this 65, 13 prefer red, so 13/65=0.20,
of the people who preferred a rainbow color,
20% preferred red.
Step-by-step explanation:
The percentage of those people who preferred red is 20%.
What is a percentage?
The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying it by 100.
The percentage change is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Considering only the people who named a rainbow color (red, orange, yellow, green, blue, or purple).
This means,
Total percentage.
= (13 + 4 + 5 + 15 + 16 + 12)
= 65%
Now,
The percentage of those people preferred red.
= 13%/65% x 100 %
= 13/65 x 100
= 20%
Thus,
The percentage of those people who preferred red is 20%.

Enter the answer in the box.
Answers
Answer:
7
Step-by-step explanation:
The interquartile range of the data set is 7.
Step-by-step explanation:
The given set of data is
(18, 17, 10, 25, 20, 20, 30, 18, 18, 30, 25)
Arrange the data in ascending order.
10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30
Divide the data in two equal parts.
(10, 17, 18, 18, 18), 20, (20, 25, 25, 30, 30)
Divide each parenthesis in 2 equal parts.
(10, 17), 18, (18, 18), 20, (20, 25), 25, (30, 30)
Now we can say that,
Q1 = 18, Median = 20, Q3 = 25
Interquartile rage of a data is
I.Q.R. Q3 Q₁
I.Q.R.25-18=7
Therefore the interquartile range of the data set is 7.

(PLS HELP MY TEACHER WANTS ME TO PASS THIS!) Which line on the graph is the image of the line y = 2x after a transition of 3 units along the x-axis and 4 units along the y-axis?
Line A
Line B
Line C
Line D
Answers
Line y=2x ==> No matter what value Y gets, X is always half of it
But X was transitioned by 3 units and Y by 4, so let's pull them back down
==> y-4 = 2x-3
Upon verifying each of the lines with y = 6:
A. 6-4 = -4-3 ==> 2 = -7. A falls
B. 6-4 = 4-3 ==> 2 = 1. B falls, but this one's the closest to truth
C. 6-4 = 8-3 ==> 2 = 5. C and D will obviously fail because X is so far ahead.
Out of testing, B is the only correct answer, despite the answers being close instead of true

Answer:
1. The relative frequency of heads is (A) reasonably close to 40%.
2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.
3. This means that the theoretical probability of tails is most likely 0.6 for this coin.
( I also had this question before)
Answer: I think the answers are
(Q1) is A (Q2) is A and (Q3) is B
Step-by-step explanation: A for the first question because the Law of probability says: If you run a shorter trial then you get biased results but run a more extended trial you get unbiased results and his results would have to be true also the relative frequency is 0.6

Step-by-step explanation:
To find the volume of the shape first we have to split the shape into two rectangles; a large one at the bottom and a small one at the top. The formula to find volume of a rectangle is
[tex]v = length \times width \times height[/tex]
note that after both volumes are found they should be added to determine the volume of the entire shape*
The length of the large rectangle is 5m, the width is 7m, and the height is 6m. Therefore the volume is
[tex]v = l \times w \times h \\ v = 5 \times 7 \times 6 \\ v = 210 {m}^{3} [/tex]
The length of the small rectangle is 5m, the width is 3m, and the height is 1m. Therefore the volume is
[tex]v = l \times w \times h \\ v = 5 \times 3 \times 1 \\ v = 15 {m}^{3} [/tex]
[tex]210 {m}^{3} + 15 {m}^{3} = 225 {m}^{3} \\ therefore \: the \: volume \: of \: the \: \\ entire \: shape \: is: \\ 225 {m}^{3} [/tex]
Answer:
[tex]V_{\ total}=225\ m^3[/tex]
Step-by-step explanation:
Step 1: Find the volume of the big box
[tex]V_{\ big} = l * w * h[/tex]
[tex]V_{\ big} = 7\ m * 5\ m * 6\ m[/tex]
[tex]V_{\ big} = 210\ m^3[/tex]
Step 2: Find the volume of the small box
[tex]V_{\ small} = l * w * h[/tex]
[tex]V_{\ small} = 3\ m * 5\ m * (7\ m - 6\ m)[/tex]
[tex]V_{\ small} = 3\ m * 5\ m * 1\ m[/tex]
[tex]V_{\ small} = 15\ m^3[/tex]
Step 3: Combine the volumes
[tex]V_{\ total}=V_{\ big} + V_{\ small}[/tex]
[tex]V_{\ total}=210\ m^3 + 15\ m^3[/tex]
[tex]V_{\ total}=225\ m^3[/tex]
Answer: [tex]V_{\ total}=225\ m^3[/tex]

(C)a)6
i didnt know how to do b
Step-by-step explanation:
it is bcz 99÷16 is 6
Answer:
(a) 3 rows had 16 chairs.
(b) 3 rows had 17 chairs.
Explanation:
There must be 6 rows, which is constant.
Make equation's:
1st equation: 16p + 17w = 99
2nd equation: w + p = 6, w = 6 - p
Solve by substitution:
⇒ 16p + 17(6 - p) = 99
⇒ 16p + 102 - 17p = 99
⇒ -p = -3
⇒ p = 3
Then find w, w = 6 - p = 6 - 3 = 3
Hence, there is 3 rows of 16 chairs and 3 rows of 17 chairs.
Try to match match and confirm the answer:
17 × 3 + 16 × 3 = 99 chairs in 6 rows1. How can you find the area of a circle?
