Rob has a piece of rope that is 126 inches long he cuts the roping to 8 inch pieces how much rope does Rob have left over

.75 inches i think because if you divide the total by 8, it gives you 15.75 so there would be 15 eight inch pieces and a left over of .75 in.

A slice is made parallel to the base of a square pyramid. What is the shape of the resulting two-dimensional cross-section?

Answer:

You get a square, I just took the test and got it right.

Step-by-step explanation:

with a square pyramid the base would be square so by cutting parallel of the shape you basically are left with the shape of the base.

A solid oblique pyramid has a regular pentagonal base. The base has an edge length of 2.16 ft and an area of 8 ft2. Angle ACB measures 30°.

Volume of the pyramid:
V = 1/3 · B · h
B = 8 ft²
tan 30° = height / 7√3
1/√3 = height / 7√3
height = 7 ft
V =  1/3 · 8 · 7 = 18.67 ft³ ≈ 19 ft³
Answer : D ) 19 ft³

Tyesha found that the z-statistic was 2.1 and that the critical z-values were -1.96 and 1.96. Which of the following is a valid conclusion based on these results?

z=2.1 falls outside the region |z|<1.96, which suggests that |z|>1.96 is the rejection region for a hypothesis at a 5% significance level. (We know this because \mathbb P(|Z|<1.96)\approx0.95.) Because z falls in the rejection region, presumably this means you are rejecting some null hypothesis. But it's difficult to say for certain without any more information.

Thanh and her crew are building a stage in the shape of a trapezoid for an upcoming festival. The lengths of the parallel sides of the trapezoid are 14 ft and 24 ft. The height of the trapezoid is 12 ft. What is the area of the stage?

Answer: 228\ ft^2

Step-by-step explanation:

Given: The lengths of the parallel sides of the trapezoid are 14 ft and 24 ft. The height of the trapezoid= 12 ft.

We know that area of trapezoid is given by :-

\text{Area of trapezoid}=\frac{1}{2}(a+b)h, where a and b are the parallel sides and h is the height of the trapezoid.

Now, the area of the trapezoid shaped stage is given by :-

\text{Area of stage}=\frac{1}{2}(14+24)(12)\\\\\Rightarrow\text{Area of stage}=(38)(6)\\\\\Rightarrow\text{Area of stage}=228\ ft^2

A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of blue results for 200 trials. Red :15 Orange : 16 Yellow :14 Green : 19 Blue : 19 16 20 32 4

Answer:  46

Step-by-step explanation:

From the table , The number of times spin got results as blue = 19

Total results = 15+16+14+19+19=83

Then , the experimental probability to get blue :-

\dfrac{19}{83}

If the total number of trails = 200

Then , the estimated number of blue results = \dfrac{19}{83}\times200

=45.7831325301\approx46

Hence, the predicted number of blue results for 200 trials= 46

QUESTION POSTED AT 23/02/2020 - 11:54 PM

John's room is shaped like a box. It has a flat ceiling that is a rectangle that is 14 feet long and 8 feet wide and the walls are 7 feet high. It has one door that is 6 feet high and 3 feet wide. It has two windows that are each 3 feet high and 30 inches wide. John wants to paint the walls and ceiling, but not the door or windows. He can paint 100 square feet with a quart of paint and paint costs $3.50 per quart. He has to buy whole quarts and may have some paint left over. It will cost John to paint his room.

Answer:

It will cost John $14 to paint his room.

Step-by-step explanation:

We have to calculate the whole area (in square feet) that John would have to paint. This area would include the area covered by the ceiling and walls, and exclude the area covered by the door and two windows:

1. Area covered by the ceiling = 14 × 8 = 112 square feet

2. Area covered by walls = perimeter of ceiling × height of wall = 2 × (14 + 8) × 7 = 308 square feet

3. Area covered by the door and two windows = (6 × 3) + (3 × 2.5 × 2) = 33 square feet

(Note: width of window = 30 inches = 2.5 feet)

Therefore, the area that would need to be painted = 112 + 308 — 33 = 387 square feet.

If John can use one quart to paint 100 square feet at $3.50, then he would need 3.87 quarts to paint 387 square feet; however, since he has to buy whole quarts, he would need 4 quarts instead of 3.87, and this would cost = 4 × 3.50 = $14

the inside's circle area
A= π x 6²=36π
the outer's
A' = 
π x 4x²= 4πx²
A'-A=4
πx²- 36π=160πcm² equivalent to x²- 9=40, so x²=49 implies x =sqrt(49)=7, x=7
