Number Two:
The formula to find the volume of a triangular prism is the area of the triangle/base multiplied by the height.
Finding the area of the base:
10×15=150×0.5=75
Now multiply it by its height.
75×25
1,875 m³
Number Four:
You need to multiply the width times the height times the length, or in any arrangements. Everything needs to get mutiplied together.
1×2.5
2.5×9
22.5 cm³

Answer:
112.5 minutes
Step-by-step explanation:
Working together, Daniel and Donnie can clean the llama pen in 50 minutes. On his own, Daniel can clean the pen in 90 minutes.
Let the number of minutes it takes Donnie to clean his Ilama pen be represented by: x
Hence, we have the expression:
1/90 + 1/x = 1/50
The Lowest Common Denominator for the left hand side = 90x
Hence:
x + 90/90x = 1/50
Cross Multiply
50(x + 90) = 90x
50x + 4500 = 90x
Collect like terms
4500 = 90x - 50x
4500 = 40x
Divide both sides by 40
x = 4500/40
x = 112.5 minutes
Therefore, it takes Donnie 112.5 minutes to clean the llama pen on his own.
The equation is actually
. Free fall is always -16t^2 as the position function. We are looking for how long it takes the object to hit the ground. In other words, the height of an object is 0 when it is laying on the ground, so how long (t) did it take to get there? We will then set that position equal to 0 and solve for t.
. If we subtract 1437 from both sides and divide by -16, we have
. Taking the square root of both sides gives us, rounded to the nearest tenth, t = 9.5 or t=-9.5. The 2 things in math that will never EVER be negative are time and distance/length, so -9.5 is out. That means that it took just about 9.5 seconds for the object to fall to the ground from a height of 1437 feet when pulled on by the force of gravity.
