Answer:

B. 85

Step-by-step explanation:

We have been given an expression 2x^3+3y^2-17. We are asked to find the value of expression, when x=3 and y=4.

To find the value of our given expression, we will substitute x=3 and y=4 in our expression as:

2(3)^3+3(4)^2-17

2*27+3*16-17

54+48-17

102-17

85

Therefore, the value of expression at the given values would be 85.

Chaney deposits $1435.73 into a savings account that pays a simple annual interest rate of 1.32%. How much interest will she ear
Aneli [31]

Answer:

Interest Chaney earns after 3 years is  $56.85

Step-by-step explanation:

Given:

Amount deposited = $1435.73

Simple annual interest rate = 1.32% = 1.32/ 100 = 0.0132

To find: Interest after 3 years

We know that the formula to calculate the interest amount is

Simple interest (S.I.) = \frac{Prt}{100}

where,

P is the initial amount deposited

r is the rate of simple interest in percentage

t is the time in years for which interest is to be calculated

Substituting the known values in the formula, we get

S.I = \frac{1435.73 x 1.32 x 3}{100}

    = 56.85

Hence the interest Chaney earns after 3 years is  $56.85

what is the volume of the rectangular prisms with a length of 1 5/8, a width of 3/8, and a height of 3in
SVEN [57.7K]

Answer:

To find the volume of a cube one must multiply all three dimensions together. Here we know two of the dimensions and the volume but not the third dimension. First I multipl together to two known dimensions: 3/4 x 1/2 = 3/8. Next I divide the volume by this answer by using the reciprocal of 3/8 and multipling. 21/32 x 8/3 = 7/4 by cancelling the 32 with the 8 and the 21 with the 3. Now 7/4 must be changed into a mixed number. Divide the numerator by the denominator and write the remainder as a fraction. 7/4 = 1 3/4.
