Given the isosceles trapezoid, find the value of x

**Answer:**

x = 11

**Step-by-step explanation:**

The lower base angles are congruent, so

4x + 41 = 85 ( subtract 41 from both sides )

4x = 44 ( divide both sides by 4 )

x = 11

A company that makes robotic vacuums claims that their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. The consumer group plans to test the hypotheses H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model. Are the conditions for inference met?

No, the random condition is not met.

No, the 10% condition is not met.

No, the Normal/large sample condition is not met.

Yes, all conditions for inference are met.

**Answer:**

**Do 15^2 +10^2=c^2 than put answer Into \sqrt()**

**Step-by-step explanation:**

**Step-by-step explanation:**

Ok, so the pythagorean theorem is **a^2 + b^2 = c^**

where c is the hypotenuse and b and a are the the other 2 sides

**9)** 10^2 + b^2 = 15^2

100 + b = 225

-100 -100

b^2 = 125

sqrt of 125 = 5

**b = 5**

**10)** 2^2 + 5^2 = C^2

4 + 25 = c^2

sqrt of 29 = c

**c = **[tex]\sqrt{29\\}[/tex]

**11)** 42^2 + a^2 = 48^2

1764 + a^2 =2304

-1764 -1764

a^2 = 540

**a = **[tex]6\sqrt{15}[/tex]

(x+3)^2=43

The volume of a cylinder is 14,130 ft 3 . If the diameter is 30 feet, calculate the height of the cylinder

**Answer:**

**V = PI*r2h**

**In plain english the volume of a cylinder can be calculated by squaring the radius, multiplying that value by PI, then multiplying by the height. You can also think of it as finding the area of a flat circle (PI * radius squared) and multiplying by the height to find volume.**

**Here is a step-by-step case that illustrates how to find the volume of a cylinder with a radius of 3 inches and a height of 5 inches. In this example PI will be 3.14.**

**V = pi * r2 * h**

**= pi * 32 * 5**

**= pi * 9 * 5**

**= 3.14 * 45**

**= 141.37 cubic inches**

**Step-by-step explanation:**

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.

The **height **of the **cylinder **is given by h = 20 feet

A **cylinder **is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of **Cylinder **= πr²h

Surface area of **cylinder **= 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the **height **of the **cylinder **be h

Now , the volume of the cylinder V = 14,130 feet³

The diameter of the cylinder d = 30 feet

So , the radius of the cylinder r = d/2 = 15 feet

And , Volume of **Cylinder **= πr²h

On simplifying , we get

14,130 = π( 15 )²h

Divide by 225 on both sides , we get

πh = 62.8

Divide by π on both sides , we get

h = 62.8 / 3.14

h = 20 feet

Therefore , the value of h is 20 feet

Hence , the **height **of the **cylinder **is 20 feet
