Basim used a trailer to haul dirt. The trailer is in the shape of a rectangular prism. The interior of the trailer has a length of 8 feet, a width of 4 feet, and a height of 2 feet. What is the total number of cubic feet of dirt that the trailer can hold when it is filled so that the dirt is level with the top?
Answer:
64 cubic feet
Step-by-step explanation:
The Volume of a rectangular prism = Length × Width × Height
Hence,
length = 8 feet
width = 4 feet
height = 2 feet.
Volume of the rectangular prism =
8 feet × 4 feet × 2 feet
= 64 cubic feet
The total number of cubic feet of dirt that the trailer can hold when it is filled so that the dirt is level with the top is 64 cubic feet of dirt

What is an equation of the line that passes through the point (-1,-3) and is parallel to the line 4x-y=2
Its not y=4x+11 that was incorrect
Answer:
y=4x+1
Step-by-step explanation:
1. 4x-y=2
-y=-4x+2 divide both sides by -1
y=4x-2
2. y-y1=m(x-x1)
y-(-3)=4(x-(-1))
y+3=4x+4
y=4x+4-3
y=4x+1
Parallel lines have the same, so the equation we are making should have the slope of 4.
if x+3y upon 5x+4y= 1/3 find the ratio of x:y ANSWER FASTTT
Answer:
x : y = 5 : 2
Step-by-step explanation:
Given
[tex]\frac{x+3y}{5x+4y}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
5x + 4y = 3(x + 3y)
5x + 4y = 3x + 9y ( subtract 3x from both sides )
2x + 4y = 9y ( subtract 4y from both sides )
2x = 5y ( divide both sides by 2 )
x = [tex]\frac{5}{2}[/tex] y ( divide both sides by y )
[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{2}[/tex] , that is
x : y = 5 : 2
Answer:
x/y = 5/2
Step-by-step explanation:
hello :
(x+3y) /( 5x+4y)= 1/3 means : 5x+4y = 3(x+3y)
5x+4y = 3x+9y
5x-3x = 9y - 4y
2x = 5y
now divid by y : 2x/y = 5y/y
2x/y = 5 so : x/y = 5/2
M {-5,2} and N {5,2} are the endpoints of the segment MN on the coordinate plane what is the length of MN?
Answer:
Length MN = 10 unit
Step-by-step explanation:
Given: M {-5,2} and N {5,2} are the endpoints of the segment MN.
Length of line segment having co-ordinates as
[tex](x_1, y_1) and (x_2, y_2)[/tex]
is calculated as
[tex]D =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
So plugging the values in above equation we get
[tex]D =\sqrt{(5+5)^2+(2-2)^2}[/tex]
D = 10 unit
Therefore, Length MN = 10 unit

Answer:
33,333 ft^3
Step-by-step explanation:
A pyramids volume can be defined by V=lwh/3. We know the base is 1000 ft^2, so we multiply that by an additional 100 for the height. We then have 100,000 ft^3. After that, we simply divide it by three, which is 33,333.3 repeating, and round it to 33,333 ft^3

Permutations acellus How many ways can 4 books be arranged on a shelf if there are 8 books to chose from? Note: nPr = n! —— (n-r)!
Answer:
1680 ways
Step-by-step explanation:
From the question,
nPr = n!/(n-r)!.................. Equation 1
Where, n = Total number of books to chose from, r = number of books to be arranged in the shelf.
Given: n = 8 books, r = 4 books.
Substitute into equation 1
8P4 = 8!/(8-4)!
8P4 = 8!/4!
8P4 = (8×7×6×5×4!)/4!
8P4 = 1680 ways.
Hence the number of ways 4 books can be arranged in a shelf if there are 8 books to chose from is 1680 ways

-3/4-__=1/2
-2 3/8-(-4 2/3) = __
Answer:
10.75
-5/4
2 7/24
Step-by-step explanation:
1.)
__+-3.5=7.25
Let missing number = x
x - 3.5 = 7.25
x = 7.25 +3.5
x = 10.75
2.)
-3/4-__=1/2
Let missing number = x
-3/4 - x = 1/2
-3/4 - 1/2 = x
(-3 - 2) / 4 = x
-5/4 = x
3.)
-2 3/8-(-4 2/3) = x
-2 3/8 + 4 2/3 = x
-19/8 + 14/3 = x

What is m∠1? HELP PLEASE
Answer:
180 degrees
Step-by-step explanation:
Since the angles of a triangle will always be 180 you just have to find the other angles. You already know that one is 34 degrees, but the angle that is 140 degrees is a supplementary angle becuase if you see the bottom line it is straight and that means that you can make 140+x=180 and if you subtract 140 from both sides you know that the inside angle equals 40 degrees. If you add 34 and 40 together you get 74 and when you subtract that from 180 you get 106 so that means the measure of angle 1 is 180 degrees
Which of the equations shows an application of the Zero Property of Multiplication? A. 25+0=25 B. 13(3)= C. 0∙2=0 D. (34−2)−(34+3)=−5
Answer:
0∙2=0
Step-by-step explanation:
Zero Property of multiplication is as follows :
The product of a number and 0 is equal to 0.
In option (c), 0 is multiplied by 2 and as a result, we get 0 as the answer.
It means,
0∙2=0
Hence, option (c) i.e. 0∙2=0 shows the Zero Property of Multiplication.
