Answer:
square pyramid
Step-by-step explanation:
a square pyramid by definition has a base that is square and its extruded sides taper to a point which is not in the same plane as the square
In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
= 0.5 * 1000 * (20)^2
= 0.5 * 1000 * 400
= 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.
To multiply one number ( a multiplicand ) by another ( a multiplier ) means to repeat a multiplicand as an addend times. The result of multiplying is called a product. The operation of multiplication is written as: 12 x 6, or 12 * 6
Multiply 12 by 6
6 is called the Multiplier
12 is called the Multiplicand
72 is called the Product
Therefore, a multiplicand and a multiplier are called factors or multipliers.

Answer:
100rz cents.
Step-by-step explanation:
The price of cement with respect to its weight is proportional.
So, we can write p ∝ w
where p is the price in dollars and w is the weight of the cement in pounds.
⇒ p = kw ............... (1) {Where, k = proportionality constant}
Given that, one pound of cement cost r dollars.
So, from equation (1), we can write
r = k(1)
⇒ k = r
So, the equation becomes p = rw .............. (2)
Now, for w = z pounds, the price will be p = rz dollars. {From equation (2)}
Therefore, the price of z pounds in cents will be 100rz cents. (Answer)
The answer is -7 over 4 -7/4
