A rectangular prism as a width of x inches, a length of x^2y
inches, and a height of y^2
inches. Which expression represents the volume in cubic inches of this rectangular prism?
A. x^2 y^2
B. 4x^2 y^2
C. x^3 y^3
D. 4x^3 y^3
Answers
Answer:
C
Step-by-step explanation:
The volume of a rectangular prism is given by:
[tex]V=\ell wh[/tex]
The width is x, the length is x²y, and the height is y². Thus, the volume is:
[tex]V=(x)(x^2y)(y^2)[/tex]
Multiply:
[tex]V=x^3 y^3[/tex]

Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. Given that the investment yields 2.7% simple interest annually, how big was the initial deposit?
a. $2,524.50
b. $4,024.03
c. $4,250.00
d. $11,404.88
Answers
Answer:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.Solving our equation:
P = 6774.5 / ( 1 + (0.027 × 22)) = 4250P = $4,250.00The principal investment required to get a total amount, principal plus interest, of $6,774.50 from simple interest at a rate of 2.7% per year for 22 years is $4,250.00I do exams and quizzes if your interested!The initial deposit amount is $4,250.00.
Given that,
The worth of an investment is $6774.50The time period is 22 years. The rate of interest is 2.7%.Based on the above information, the calculation is as follows:
We know that
[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]
Now
Investment worth = P + SI
= P + 0.594P
= 1.594P
So,
1.594P = 6774.50
P = $4,250
Therefore we can conclude that the initial deposit amount is $4,250.00.

km= 300 x 16 ÷ 25
=4800 ÷ 25
= 192
Answer:
260 km for 300 mins
Step-by-step explanation:
16 km in 30 mins (half an hour)
There are 300 minutes in 5 hours
16 km for 30 mins
32 km for 60 mins
48 km for 90 mins
64 km for 120 mins
80 km for 150 mins
96 km for 180 mins
112 km for 210 mins
128 km for 240 mins
144 km for 270 mins

( all you need to do is keep on adding 16 km and 30 mins until you get to 5 hours/300 mins)
So the truck covers a distance of 260 km for 300 mins

What is the minimum value for the function shown in the graph?
Answers
Answer:
2.5
The lowest point on the graph, or the minimum is at f(x)= 2.5
The minimum value of the given periodic function is, 2.5
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
A periodic function,
Period = 3π
The value of the function is in the range of (2.5, 4.5)
So,
Maximum value = 4.5
Minimum value = 2.5
Thus, the minimum value is 2.5

James, Ryan and Jill share £120 in the ratio 3:2:1.
Find out how much each person recieves.
Answers
Answer:
James = £60, Ryan = £40 and Jill = £20
Step-by-step explanation:
James - 3, Ryan - 2 and Jill - 1
3 + 2 + 1 = 6
£120 / 6 = 20
Times 20 by each of the three numbers (3, 2 and 1)
3 x 20 = £60 (James)
2 x 20 = £40 (Ryan)
1 x 20 = £20 (Jill)
Answer:
James gets £60
Ryan gets £40
Jill gets £20
Step-by-step explanation:
Add up the ratio which would be 6 then divide it by the original sum which is £120 so the answer would be 20. You would then multiply 20 by each number so 20x3= 60. 20x2= 40. 20x1=20
All these should add up to your original sum and if they do you know you've done it right!
