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.

Does anyone know what the answer please!?????????
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

Two friends, Chespirito and Quico, are racing down a mountain. Quico is 17.6 miles away from the Finish Line and runs 2.6 miles per hour. Chespirito is 22.8 miles from the Finish Line, but runs 3.9 miles per hour. How many hours will it take Chespirito to catch up with Quico? It will take Chespirito hours to catch up with Quico.
Answer:
4 hrs
Step-by-step explanation:
22.8-17.6=5.2
so they are 5.2 miles apart.
Let they meet after t hrs.
distance coverd by Quico in t hrs=2.6t
distance covere by Chespirito in t hrs =3.9t
3.9t-2.6 t=5.2
or 1.3 t=5.2
t=5.2/1.3 =4

Step-by-step explanation:
Identify the volume of a regular triangular pyramid with base edge length 14 ft and height 9 ft.
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
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
Find the function rules.

Step-by-step explanation:
Truck A leaves station 1 at 9:00 a.m. and travels at the rate of 60 kph. After 2 hours, Truck B leaves the same station and travels in the same direction at the rate of 80 kph. At what time will Truck B overtake Truck A?
Answer: [tex]5:00\ PM[/tex]
Step-by-step explanation:
Given
Truck A speed is [tex]v_a=60\ kmph[/tex]
Truck B speed is [tex]v_b=80\ kmph[/tex]
Truck A leaves 2 hours before truck B
Distance traveled in the 2 hour
[tex]\Rightarrow 60\times 2=120\ km[/tex]
Suppose Truck B will catch truck A after t hours
[tex]\therefore 120+60t=80t[/tex]
[tex]\Rightarrow 120=20t\\\Rightarrow t=6\ hr[/tex]
Overtake time is [tex]9:00am +2+6=5:00\ PM[/tex]
Solve the quadratic equation by factoring.
6x 2 + 24x = 0
Answer:
x=0
2(3x+12x)
FACTORED ANSWER
2(15)x)
Step-by-step explanation:
Answer:
[tex]x = 0[/tex]
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.
[tex]12x \times 3 = 0[/tex]
multiply 3 by 12.
[tex]36x = 0[/tex]
Divide each term by 36 and simplify.
[tex]x = 0[/tex]
therefor, the answer is 0.
