A block of marble is in the shape of a rectangular prism. The block is 2 feet long. 3 feet wide, and 90 inches high. What is the volume of the block? The volume of the block is cubic feet​

Answers

Answer 1

Answer:

Volume of a rectangular prism can be found with the equation

v = length × width × height

They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...

18 inches = 1.5 ft

v = l×w×h

v = 3×2×1.5

v = 9 ft^3

Answer 2

Volume=length*width*height, so first you would have to change the units of the inches to feet, which would be 90/12=7.5, so now you can fit that into the equation, 2*3*7.5=45 ft cubed!

Step-by-step explanation:

3(x-y)-3x-7y=3(5)-(-5)

3x-3y-3x-7y=15+5

-10y=20

y=-2, since x-y=5

x-(-2)=5

x+2=5

x=3

The length of a rectangle is units greater than twice its width. If its width is w, which expression gives the perimeter of the rectangle in terms of w?
A.
2(w) + w
B.
w + w
C.
3w +
D.
6w + 5

Answers

The expression which shows the perimeter in terms of w is option d which is 6w+5.

What is expression?

Expression is a combination of numbers, fraction, symbols, indeterminants, determinants,etc. It shows a relationship between two or more variables. It is mostly not found in equal to form.

How to find perimeter?

We have been given that width be w, so the length will be 2w+5/2.

We know that perimeter of rectangle is 2(l+b)

Perimeter=2(2w+5/2+w)

=2(3w+5/2)

=2(6w+5)/2

=6w+5

Hence the the expression which shows the perimeter of rectangle having width w and length is 5/2 units greater than double the width in terms of w is option d which is 6w+5.

An interior designer wants to place this bed in a home, and she is especially concerned about the headboard, which is 6 feet wide and 5 feet tall. She’ll place the headboard on a wall that is 7 feet wide and 9 feet tall. She needs to know the area of the space that will remain after she places the bed against the wall

Answers

Answer:

Step-by-step explanation:

Area of the Wall minus the Area of the headboard      

Area = length x width      in  this use tall as length and wide as width

Area Wall - Area Headboard  =  (Tall wall)(Wide wall)  -  (Tall head)(Wide head)

                 =  (9)(7) - (5)(6) feet

                 =    63 - 30  feet

                 =   ????                      I'll let you finish it

The area of the space that will remain after she places the bed against the wall is 30 feet².

What is Area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

We have,

The headboard, which is 6 feet wide and 5 feet tall.

The headboard on a wall that is 7 feet wide and 9 feet tall.

So, Area of remaining space

= Area of the Wall - Area of the headboard      

= (9)(7) - (5)(6) feet

= 63 - 30  

= 30 feet²
