How many square feet of outdoor carpet will we need for this hole​

Mathematics
1 answer:
tester [92]3 years ago
3 0

Answer:

42 ft²

Step-by-step explanation:

First of all, who makes a hole in this shape?

Anyways,

You're going to want to split the figure into multiple different shapes. We already have a triangle, so I would split the remaining shape into a rectangle and trapezoid.

We can find the area of the triangle easily with the equation 1/2(bh)

So

1/2(2 · 3)

1/2(6)

3

So the triangle is 3 ft²

Now we can find the area of the rectangle.

The measurements will be 3 and 7. It's just base x height so it'll be 21 ft²

Finally the trapezoid.

Base 1: 6

Base 2: 3

Height: 4            (11-7)

Formula: 1/2h (b1 + b2)

1/2 · 4 (6+3)

2(9)

18 ft²

Now just add them together:

3+21+18=42

Hence, your answer is 42 ft²

What you have to do is multiply each of the sides so you have 80, 60, and 48.

Add those up to get 188. Then multiply this by 2 and you get 376.

Your answer is D. (376)

P.S if this helped you out, please give me brainliest if you don't mind. I am only a few more from leveling up :D

A sample of 84 full electric cars was randomly drawn from a population with an unknown mean range μ (miles per charge) and a sta
forsale [732]

Answer:

(a) The test statistic value is -1.83.

(b) We accept the null hypothesis at α = 0.01.

Step-by-step explanation:

The information provided is:

 n=84\\\bar x=125\\\sigma=25\\\alpha =0.04

The hypothesis is defined as follows:

<em>H₀</em>: <em>μ</em> ≥ 130 versus <em>Hₐ</em>: <em>μ</em> < 130.  

Since the population standard deviation is provided, we will use a z-test.

Compute the test statistic as follows:

 z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{125-130}{25/\sqrt{84}}=-1.83

The test statistic value is -1.83.

(b)

Compute the p-value of the test as follows:

p-value = P (Z < -1.83)

= 0.034

* Use a z-table.

We reject a hypothesis if the p-value of a statistic is lower than the level of significance α.

• p-value = 0.034 < α = 0.04. Reject the null hypothesis.

• p-value = 0.034 > α = 0.01. Fail to reject the null hypothesis.

• p-value = 0.034 < α = 0.05. Reject the null hypothesis.

• p-value = 0.034 < α = 0.10. Reject the null hypothesis.

Mission Control sends a signal to a Mars robot to travel to a mysterious rock 52.8 meters away. A return signal 59.0 minutes lat
Andrei [34K]
The response time includes the round-trip signal time plus the robot's travel time.
  59 min = 2*(9.5 min) +travel time
  59 min -2*(9.5 min) = travel time = 40 min

The speed is distance / travel time
  speed = (52.8 m)/(40 min) = 1.32 m/min

The robot's average speed was 1.32 meters per minute.
