A rectangular prism has a length of 8 meters, a width of 6 meters, and a height of 3 meters.
Which equations could be used to determine the volume, V, of the prism?
Select each correct answer.
(A) V = 8 × 6 × 6
(B) V = 8 × 6 × 3
(C) V = 8 × 9
(D) V = 48 × 3
Answer:
(B) V = 8 x 6 x 3
Step-by-step explanation:
The formula to find the volume of a rectangular prism is, V = Length x Width x Height cubic units.
V = 8 x 6 x 3 cm 3.
V = 192 cm 3.

Dr.Purple wants to buy candy bars for all his 143 math students. He buys 9 cases plus 8 more individual bars. How many bars are in each case?
There is 15 bars in each case.
Subtract 8 from 143 and you get 135.
Divide 135 by 9 and you get 15 :)
Answer:
143 - 8 = 135
Then 135 ÷ 9 = 15
Answer 15 bars in each case.

martin works in a furniture store. he earns a base salary of $1,800 per month, plus a 15% commission on the amount of furniture sales he makes during the month. if martin needs to earn at least 3,000 each month to pay his expenses, what is the minimum amount of furniture sales he must make each month?
Answer:
$8000
Step-by-step explanation:
With the provided values you get the equation
1800+.15x=3000
with x being the amount of sales he needs
1. 3000-1800=1200
gives 1200=.15x
2. 1200/.15 = 8000
so x = 8000
You are arranging 60 pictures on a poster board. the board can fit up to 4 rows of pictures and each row can have up to 20 pictures. you want each row to have the same numbers of pictures. how many different ways can you arrange the pictures?
Answer:
2 different ways
Step-by-step explanation:
You are looking at the factors of 60.
1×60 does not work, too many pictures in a row.
2×30 does not work, too many pictures in a row.
3×20 THIS WORKS!
4×15 THIS ALSO WORKS!
5×12 Nope, too many rows
6×10, no, too many rows
So there's just two ways to arrange the pictures.

I NEED HELP WITH THIS MATH I DONT GET IT!!!!!
Answer:
It's 5
Step-by-step explanation:
-4x+5=-15 (subtract 5)
-4x=-20 (divide by -4)
x=5
Step-by-step explanation:
Work backwards. First, create a function:
f(x) = x
First, instead of adding 5, subtract it:
f(x) = x - 5
Then, divide by -4:
f(x) = (x - 5) ÷ -4
Then plug in -15:
f(-15) = (-15 - 5) ÷ 4
= -20 ÷ -4
= 20 ÷ 4

Ricky is 5 years older than Ciara. In 6 years the sum of their ages will be 53. How old is Ricky now
Answer:
23 years old
Step-by-step explanation:
Given the following question:
Ricky is 5 years older than Ciara...
6 years their ages will equal 53 years of age.
So, we have to remember that in six years their ages will equal 53 and one is five years older than the other.
[tex]23+6=29[/tex]
[tex]18+6=24[/tex]
[tex]29-5=24[/tex]
[tex]29+24=53[/tex]
[tex]29-6=23[/tex]
[tex]=23[/tex]
Which means Ricky as of right now is "23 years of age" and Ciara as of right now is "18 years of age".

Paulo has R$80.00 and Carlos has 2/3of that amount. How many Carlos has? How many do the two have together?
Answer:
53 dollars and 33 cents
Step-by-step explanation:
53.33
We are given –
Paulo has R$ 80.00 and Carlos has 2/3 of that amount.
We are asked to find, how much Carlos owns and how much they have together.
Explanation :-
At first, we just need to multiply 80by 2, and then we will divide the value by 3, so we find that:
[tex]\qquad[/tex][tex] \bf \longrightarrow 80 \times 2 = 160[/tex]
[tex]\qquad[/tex][tex] \bf \longrightarrow \dfrac{160}{3} = 53.3[/tex]
Therefore, we find that Carlos has 53.3 R$.
Now to find out how much they have together. We have to add Paul's amount to Carlos' amount for that.
[tex]\qquad[/tex][tex] \bf \longrightarrow 53.3 +80 =133.3[/tex]
Henceforth, they both have 133.3 R$. together.
write the equation of the line?
Answer: Yellow option
Step-by-step explanation:
The points noted are (0,-2) and (3,-1)
So the slope is (-2--1)/(0-3) = -1/-3 = 1/3
So options blue, green and red are out.
So the only option is yellow

___% of $10 = $2
Please help me I can not figure it out
I need it please
Answer:
20%.Step-by-step explanation:
Sentence should be:
2 is what percent of 10.How we get the %:
To get it, we need to find the fraction of 20% (0.2) (2/10)So, we simply do this:2/10.We then get 20%.2 is 20% of 10.
20% of 10 is 2.

The points (2, 5) and (6,-3) fall on a particular line. What is its equation in slope-intercept form?
y = -2
x+ ?
Answer:
y = -2x + 9
Step-by-step explanation:
slope intercept form : y = mx + b
where m = slope and b = y intercept
first let's find the slope
slope formula :
[tex]m = ( \frac{y2 - y1}{x2 - x1} )[/tex]
where the x and y values are derived from the given points
here we are given (2,5) and (6,-3)
(x1,y1) = (2,5) so x1 = 2 and y1 = 5
(x2,y2) = (6,-3) so x2 = 6 and y2 = -3
we now plug these values into the formula
recall formula
[tex]m= ( \frac{y2 - y1}{x2 - x1} )[/tex]
plug in x1 = 2, y1 = 5, x2 = 6 and y2 = -3
m = (-3 - 5) / ( 6 - 2 )
m = (-8)/(4)
m = -2
the slope is -2
now to find the y intercept we plug in the slope and the x and y value of a given point into slope intercept form and solve for b
y = mx + b
given point : (2,5) x = 2 , y = 5, m = -2
5 = -2(2) + b
5 = -4 + b
9 = b
so the equation would be y = -2x + 9
