Answers

Answer:

-5<x<9

Step-by-step explanation:

Within a triangle, the greater an angle, the greater the length of opposite side. So, since we know that 42° gives an opposite side of 23, and (3x+15)° gives an opposite side of 21, (3x+15) must be less than 42:

3x+15<42

3x<27

x<9

We also know that the angle (3x+15)° cannot equal zero or less than zero. So find x when 3x+15=0, and note that our value for x must be greater than this:

3x+15=0

3x=-15

x=-5

so, -5<x

Put both parts together to get: -5<x<9

A silo is a storage bin that is a cylinder with a hemisphere on top. A farmer has a silo with a base radius of 30 feet and a storage height of 100 feet. The "storage height" is the part which can be filled with grain - it is just the cylinder. A cubic foot of grain weighs 62 lbs.

One thousand square feet of wheat produces 250 pounds of grain.The farmer's wheat field is 3500 feet by 20,000 feet. Is the silo large enough to hold the grain? By how much? Explain your answer.

Answers

Answer:

Step-by-step explanation:

The scale factor from 3m to 9m is ×3

So do 12 / 3 = 4

The scale factor is 4.

Since the length of one side is 9 and 3 on the other triangle, you would divide those two.

9/3=3

Then, you would decide 12 by 3 to get your final answer.

12/3=4

Identify the volume of a regular triangular pyramid with base edge length 14 ft and height 9 ft.

Answers

Answer:

The volume is 588 ft³

Step-by-step explanation:

[tex]v = a {}^{2} \frac{h}{3} = 14 {}^{2} \times \frac{9}{3} = 588[/tex]

Answer:

254.6 ft3 F

Step-by-step explanation:

To find the volume of the pyramid, first calculate the area of the base.

As the pyramid is the regular triangular pyramid, the base is an equilateral triangle.

To find the area of the equilateral triangle, calculate the length of the height.

Since the triangle is equilateral, each angle in the triangle equals 60°.

The height forms a 30°- 60°- 90° triangle. One leg of this triangle is equal to half of the side of the large triangle, or 7 ft. The other leg of the triangle is equal to 73‾√ ft by the 30°- 60°- 90° Triangle Theorem.

Therefore, the length of the height of the triangle is 73‾√ ft.

To find the area of the base of the pyramid, B, use the formula for the area of a triangle, B=12bh.

Substitute 14 for b and 73‾√ for h.

B=12⋅14⋅73‾√

Simplify.

B=493‾√ ft2

To find the volume of the pyramid, use the formula for the volume of a pyramid, V=13Bh.

Substitute 493‾√ for B and 9 for h.

V=13⋅493‾√⋅9

Simplify.

V=1473‾√

Use a calculator to approximate.

V≈254.6 ft3

Therefore, the volume of the regular triangular pyramid is about 254.6 ft3.

List the following rational numbers in order from least to greatest -1/2, 2.5, -8 1/4,
1 1/2,-1.5,3

Answers

Answer:

-8, -1.5, 1/2, 1/4, 1/2, 1, 2.5, 3

Step-by-step explanation:

Answer:

-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2 (if is not 11/2 but 1 and 1/2) the answer is : -8, -1.5 , -1/2 , 1/4 , 1/2, 1 , 2.5, 3

Step-by-step explanation:

First of all we have to express the decimal numbers with a fraction

2.5 = 25/10 = 5/2

-1.5 = -15/10 = -3/2

now we have to express al numbers with a fraction with the same denominator. In this case the value that help us the most is 4

-1/2 = -2/4

5/2 = 10/4

-8 = -32/4

1/4 = 1/4

11/2 = 22/4

-3/2 = -6/4

3 = 12/4

now we have to check only the numerators for discover the order of the numbers. So from the least to the greatest we have:

-32/4 ; -6/4 ; -2/4 ; 1/4 ; 10/4 ; 12/4 ; 22/4

the final step is rewrite the original numbers in this order

-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2

Step-by-step explanation:

Factor 6x⋅2 out of 6x⋅2+24x.

[tex]6x \times (2(1 + 2)) = 0[/tex]

Multiply 2 by 6.

[tex]12x(1 + 2) = 0[/tex]

Add 1 and 2.
