What is the value of fraction 1 over 3x3 + 5.2y when x = 3 and y = 2?

C. 19.4

just substitude the value into the equation given

Question 6(Multiple Choice Worth 1 points)
(06.01 MC)

What is the value of the expression 9 − (fraction 1 over 2)4 ⋅ 48?

D. 9

the answer is 8.9375,but the answer provided in whole number.You just need to round off to tge nearest whole number.

Question 7(Multiple Choice Worth 1 points)
(06.02 LC)

Which statement best describes the expression 2y ÷ 7?

A. 2 times y divided by 7

B,C and D are obviously wrong.It doesn't related on the equation given.A is the right answer

Question 8(Multiple Choice Worth 1 points)
(06.02 MC)

Which of these is the algebraic expression for "4 less than the product of 5 and some number?"

B. 4 − 5p

A,C and D are WRONG. it doesn't mention that 4 is the product of any unknown number.B is the right answer

Question 9(Multiple Choice Worth 1 points)
(06.06 MC)

The work of a student to find the dimensions of a rectangle of area 8 + 16x and width 4 is shown below:

A. Step 1: 8 + 16x
B. Step 2: 4(4) + 4(12x)
C. Step 3: 4(4 + 12x)
D. Step 4: Dimensions of the rectangle are 4 and 4 + 12x

In which step did the student first make an error and what is the correct step?

C. Step 2; 4(2) + 4(4x)

The first error is at the step 2.It doesn't show the right solution.4(4x),not 4(12x).That is obviously wrong.How could 16 can be 12 even the expression not multiply by any number yet ! that obviously WRONG. C is the right answer

A rectangular pyramid has a volume of 90 cubic feet. What is the volume of a rectangular prism with the same size base and same

yanalaym [24]

Answer:

30 cubic feet

Step-by-step explanation:

Here we are given the volume of rectangular pyramid as 90 cubic feet as we are required to find the volume of rectangular prism.

For that we need to use the theorem which says that

the volume prism is always one third of the volume of the pyramid . Whether it is rectangular of triangular base. Hence in this case also the volume of the rectangular prism will be one third of the volume of the rectangular pyramid.

Volume of Rectangular prism = $\frac{1}{3}$ * Volume of rectangular pyramid

= $\frac{1}{3}$ * 90

= 30

There were 27,000 people at a ball game in Los Angeles. The day's receipts were $204,000. How many people paid $13 for reserved

Studentka2010 [4]

21000 people paid for general admission and 6000 paid for reserved seats. This is solved by making 2 equations. Out of 27000 people who were at game, x of them paid for general admission and y for reserved seats, thus
x + y = 27000
As said, daily receipts were 204000$. As reserved seat is 13$, y of them gave 13$ each (y*13$) and x of them gave 6 for general admission(x*6) and those two add up and we get second equation
13y + 6x = 204000.
This can be solved by transforming first equation into x = 27000 - y and then replacing the x in second.
13y + 6*(27000 - y) = 204000
13y + 162000 - 6y = 204000
7y = 42000
y = 6000
x + 6000 = 27000
x = 27000 - 6000 = 21000
