Step-by-step explanation:
:)
Tank calculations :
Volume = 1/4(4/3 * pi * r^3)
r= 70 feet.
Volume = 1/4(4/3 * 3.14 * 70^3)
Calculating the values:
Volume = 359,000.67 ft.cubed
No we divide the actual radius by 6 to get the volume of scale model.
Hence,
6^3 = 216 times smaller.

Answer:
Choice A. Segment LM is congruent to segment LO.
Step-by-step explanation:
Triangles LMX and LOX are right triangles since we see that each one has a right angle.
Segment LX is congruent to itself. Segment LX is a side of both triangles. It is a leg of both triangles, so we already have a leg of one triangle congruent to a leg of the other triangle.
For the HL theorem to work, we need a leg and the hypotenuse of one triangle to be congruent to the corresponding parts of the other triangle. Since we already have a pair of legs, we need a pair of hypotenuses.
The hypotenuses of the triangles are segments LM and LO.
Answer: A. Segment LM is congruent to segment LO.
Answer:
C. 400 miles
Step-by-step explanation:
In each hour, it travels 80 miles. (That is the meaning of "80 miles per hour.") So you can add up the distances over a period of 5 hours:
80 miles + 80 miles + 80 miles + 80 miles + 80 miles
After the first sum (80+80=160), you can see what the correct answer will be. Continuing, you find the sum to be ...
= 400 miles
___
Multiplication was invented to make repeated addition easier.
5 × 80 miles = 400 miles
_____
Strictly speaking, you are multiplying numbers with units here:
(5 h) × (80 mi/h) = 400 mi·h/h = 400 mi . . . . . . the units h/h cancel
Answer:
Step-by-step explanation:
A <em>product</em> of two numbers is the result we get from multiplying them together. The product of 4 and x would then be 
, which we can rewrite as 
. We're then told by the statement "one minus the product..." that we'll be taking this away from 1, giving us the answer .
