The area of the base of a prism with a square base is 7,200,000/h cm to the 2nd power.
What is formula for volume of square prism?The formula for volume of square prism is given as,
Volume of a square prism = (Base Area) × Height.
Now it is given that,
Volume of prism = 7,200,000 cm to the 3rd power
Height of prism = h cm
Since, Volume of a square prism = (Base Area) × Height
Putting the values we get,
7,200,000 = (Base Area) × h
Rearranging we get,
Base Area = 7,200,000 / h cm to the 2nd power
Thus, the area of the base of a prism with a square base is 7,200,000/h cm to the 2nd power.

Answer:
X = 36.5
Z = 19
Angle RIG is 69
angle ZIM is 126.5
Step-by-step explanation:
angle AIZ and ZIP
x + 3x - 56 = 90
4x - 56 = 90
4x = 90 + 56
4x/4 = 146/4
x = 36.5
Plugin the value of x in (3x -56)
3x - 56
(3(36.5) - 56)
(109.5 - 56) = 53.5
Angle AIZ = 53.5
Angle RIG is 4z + 7. Convert the letter x in (x + 2) to Z and solve for z
4z + 7 + z + 2 = 90
5z + 9 = 90
5z = 90 - 9
5z/5 = 81/5
z = 16.2
Z + 2
16.2 + 2 = 18.2
Angle GIM is 18.2 degrees
Plugin the the value of z into 4z + 7 for angle RIG
4z + 7
(4(16.2) + 7) = 71.8
Angle RIG = 71.8 degrees

Explain. You stand at the edge of a 5m high diving platform. A beach ball is exactly 9 m from the base of the platfo
To the nearest tenth of a meter, what is the distance d from the top of the platform to the beach ball?
the distance, d from the top of the platform to the beach ball is equal to 10.29 m.
We are given that:
Height of the platform = 5 m
distance between bas of the platform and the beach = 9 m
We need to find the distance from the top of the platform to the beach ball.
We know that this distance d will be the hypotenuse of the triangle formed.
So, we have:
Perpendicular = 5 m
Base = 9 m
Hypotenuse = d
So, by using the Pythagoras theorem, we get that:
d² = 5² + 9²
d² = 25 + 81
d² = 106
d = √ 106
d = 10.29 m.
Therefore, we get that, the distance, d from the top of the platform to the beach ball is equal to 10.29 m.

Answer: The amount less will be with held weekly for federal income tax is $40.65.
Step-by-step explanation:
Given data,
Nico Joven presently earns $348.40 per week.
The amount of money deducted from federal income tax is:
= $348.40/2
= $174.20
He claims himself and his mother as allowances.
He is single. He is to get a new job classification, which will result in a 15% increase in pay.
The increase in pay will be:
= 15% × $348.40
= $52.26
After his marriage, he will claim his wife, himself, and his mother as allowances.
The new salary will be the addition which is $400.66.
The new money with held will be:
= $400.66/3

A plane is flying at a height of 35,000 ft. (feet) above sea level. At a particular point, it is directly above a submarine floating 3,500 ft. below sea level and a military drone flying at a height of 3,500 ft. By how much must the military drone ascend so that it is vertically in the middle of the plane and the submarine?
The military drone must ascend 12250 from its position of 3500ft above sea level feet so that it is vertically in the middle of the plane and the submarine.
To solve this problem we need to understand the concept of sea-level. The sea-level is defined as the average height of all water bodies of the earth. Below sea level is effectively taken as negative length and above sea -level is taken as positive length.
Let us consider the drone will have to ascend x feet to be vertically in between the plane and the submarine.
The submarine is 3500 feet below the sea level.
The plane is 35000 feet above the sea level.
Now we know that the drone is at a height of 3500 feet above the sea level.
Total distance between the drone and the ship=35000-(-3500)=38500ft
Middle point of the two=38500/2 = 19250 feet from the plane
Height above sea level for the drone should be=35000-19250=15750 ft
height of the drone=3500ft
The drone should ascend=15750-3500=12250 feet

anne and nanny use a metal alloy that is 16% copper to make jewelry how many ounces of an alloy that is 10% copper must be mixed with an alloy that is 20% copper to form 55 ounces of the desired alloy
By solving a system of equations we conclude that they need to use 22 ounces of the 10% alloy and 33 ounces of the 20% alloy.
How many ounces of each alloy should they use?
First, let's define the variables we will use to solve this problem:
x = ounces of the 10% alloy copper they need to use.y = ounces of the 20% alloy copper they need to use.We know that they want to get 55 ounces, then:
x + y = 55
And the concentration of these 55 ounces must be 16%, then we can write other equation:
0.1*x + 0.2*y = 0.16*55
Then we have a system of equations:
x + y = 55
0.1*x + 0.2*y = 0.16*55
Isolating x on the first equation we get:
x = 55 - y
Now we can replace that in the other equation so we get:
0.1*(55 - y) + 0.2*y = 0.16*55 = 8.8
Now we can solve this for y.
5.5 - 0.1*y + 0.2*y = 8.8
5.5 + 0.1*y = 8.8
y = (8.8 - 5.5)/0.1 = 33
Then the value of x is:
x = 55 - y = 55 - 33 = 22
We conclude that they need to use 22 ounces of the 10% alloy and 33 ounces of the 20% alloy.
