A triangle has side lengths measuring 3x cm, 7x cm, and h cm. Which expression describes the possible values of h, in cm?

Answers

Answer 1

Answer: The answer is 4x cm < h < 10x cm.

The third side of the triangle is greater than the difference of the lengths of the other two sides (h > 7x cm - 3x cm) and it is less than the sum of the lengths of the other two sides (h < 7x cm + 3x cm). Therefore:
h > 7x - 3x
h < 7x + 3x

This can be expressed as:
7x cm - 3x cm < h < 7x cm + 3x cm
⇒ 4x cm < h < 10x cm

Answers

Answer:

Step-by-step explanation:

Since the cookies is circular in nature, we will use the formula for calculating the area of circle to calculate the area if each cookies.

Area of each cookies = πd²/4

Given diameter d = 8cm

Area of the cookies = π(8)²/4

Area of the cookies = 64π/4

Area of the cookies = 16π cm²

Answers

The volume of the rectangular prism will be 128 cubic feet.

What is the volume of the rectangular prism?

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the rectangular prism is given as

V = L x W x H

The dimension of the prism is given below.

4 ft by 4ft by 8 ft

Then the volume of the rectangular prism will be

V = 4 x 4 x 8

V = 128 cubic feet

More about the volume of the prism link is given below.

Volume (V) = length (l) x width (w) x height (h)
V = 4 x 4 x 8
4x4 = 16, 16 x 8 = 144
V = 144 ft (cubed)

Bryant collects a set of 20 data representing the lengths of worms he found in the garden. The variance of the set of measurements is 36.What is the standard deviation from the mean

Answers

Given:
data set : 20 numbers
variance : 36

Find the standard deviation from the mean.

If the variance is already provided, we simply find the square root of the variance to get the standard deviation.

Standard deviation = √36 = 6

The standard deviation of the data from the mean is √variance, which is: 6.

What is Standard Deviation?

The standard deviation can be gotten by finding the square root of the variance of the data. That is, Standard deviation = √variance.

Given the following:

Variance = 36

Standard deviation = √36

Standard deviation from the mean = 6

I dont understand how to do these three questions

Answers

Well the first has the angles being 3x+12,x,and 90 so they have to add up to 180 degrees because it is a triangle.
3x+12+x+90 = 4x+102 = 180 solve
4x+102=180
4x=78
x=19.5
