Answer:

C

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply the width by the length by the height (the three given side lengths).

Only C and D do that. Meanwhile A and B just add them, which is not what you're supposed to do.

So, we know it's not A or B.

After finding the volume of each of the prisms, you need to add them to find the combined volume.

D multiplies them, so it's not D.

Therefore it must be C, which correctly multiplies the side lengths and then adds the volumes together at the end.

Allie deposited $80 in a savings account earning 10% interest, compounded annually. To the nearest cent, how much will she have
77julia77 [94]

Answer: $96.8

Step-by-step explanation:

Formular for Compounding annually :

A =P ( 1 + r/n) ^nt

Where p is the Principal given as $80

r is the rate given as 10% = 10/100 = 0.1

n is the number of times the principal was compounded, given as 1

t is the time, given as 2 years:

Slot the values into the formula:

A= $80 ( 1 + 0.1/1) ^ (1 × 2)

A= $80 ( 1 + 0.1) ^2

A= $80 ( 1.1) ^2

A= $80 (1.21)

A= $80 x 1.21

A= $96.8

96.8 is already rounded to the nearest cent.

Uppose that x is a bernoulli trial with p = .30. determine the mean of x.
lara [203]
The goal is not only to model the vector with 2 - D and to determine its important parameters, but also to examine the impact in the implementation. That is, Ogden's material parameters, element type, element size, and loading type.
