A water tank holds 254.34 m cm3 of water. If
the diameter of the tank is 6 meters, calculate
the height
Answers
Answer:
Height, h = 9 m
Step-by-step explanation:
Given that,
The volume of a water tank, V = 254.34 m³
The diameter of the tank, d = 6 m
We need to find the height of the clinder. The volume of a cylinder is given by :
[tex]V=\pi r^2h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{254.34}{3.14\times (3)^2}\\\\h=9\ m[/tex]
So, the height of the cylinder is 9 m.

Answer:
A. only inequality 1.
Step-by-step explanation:
The inequality 1 can be written as
- 5 = 1 - 3d
- 5 - 1 = - 3d
- 3d = - 6
d = 2
Now the inequality 2 can be written as
- 1 =( 1 - d) / 3
- 3 = 1 - d
d = 1 + 3
d = 4
So the answer is A only inequality 1.
Hope it will help :)
Alex is trying to save $230 to buy a new tablet. Right now, he has $40 and can save $38 a week from
his allowance. Write and solve an inequality that can be used to find the minimum number of weeks it
will take Alex to have the money to buy the tablet. Write a sentence to interpret your solution.
Answers
Answer:
Step-by-step explanation:
So we know that Alex is trying to save $230.
He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.
If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.
38×5= 190
Therefore, Alex will have enough money to buy a tablet in five weeks.
I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?
Answers
Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0
t=0 t=0.88
{0, 0.88}

Step-by-step explanation:
We see that one angle is 28, so because of alternate interior angles, angle two is also 28. Angle one is 90 because those two lines are perpendicular and the only available options for A is 90, and measurement angle 3 is going to be 180 - (90 + 28) (sum of interior angles in a triangle) and you're going to get 62.

A triangle has a perimeter of 15 feet. Side B is one foot longer than side A. Side C is two feet longer than side A. What is the length of each side.
Answers
Answer:
Side A = 4
Side B = 5
Side C = 6
Step-by-step explanation:
In the following equation, variable a is the length of Side A
a + (a + 1) + (a + 2) = 15
a + a + a + 1 + 2 = 15
3a + 3 = 15
- 3 - 3
3a (÷ 3) = 12 (÷ 3)
a = 4
Side A = 4
Side B = (a + 1) = (4 + 1) = 5
Side C = (a + 2) = (4 + 2) = 6
