David and Karen are building a treehouse in the shape of a rectangular prism for their daughter.If the treehouse is going to 5 f

Serga [27]

The space left inside the tree is 300 cubic feet.

David and Karen have to paint 275 square feet on the outside.

Explanation:

It is given that the length of the tree house is 7.5 feet

The width of the tree house is 8 feet

The height of the tree house is 5 feet

The tree house is in the shape of a rectangular prism.

The volume of the rectangular prism is given by

$\text {Volume}=\text {length } \times \text {width} \times \text {height}$

Substituting the values, we have,

$Volume$=7.5 \times 8 \times 5$\\Volume $=300$$

Thus, the volume of the rectangular prism is 300 cubic feet

Hence, the space left inside the tree is 300 cubic feet.

The area they have to paint on the outside can be determined using the formula for surface area of the prism .

$Area=2(w l+h l+h w)$

Substituting the values, we get,

$Area=2[(8*7.5)+(5*7.5)+(5*8)]$

Multiplying the terms within the bracket, we get,

$Area=2(60+37.5+40)$

Adding the terms, we have,

$Area=2 \times 137.5$

Multiplying, we get,

$Area =275$

Thus, David and Karen have to paint 275 square feet on the outside.

NP is an angle bisector of <MNO. If <MNP = x + 23, and m<PNO = 3x - 1, find the value of x.

Neko [114]

The answer is: " 12 " .

_____________________________________________

→ " x = 12 " .

_____________________________________________

To solve:

________________________________________________________

3x - 1 = x + 23 ; Solve for "x" ;

Subtract "x" from each side of the equation; & add "1" to each side of the equation;

3x - 1 - x + 1 = x + 23 - x + 1 ;

to get:

2x = 24 ;

Divide each side of the equation by "2" ;

to isolate "x" on one side of the equation; & to solve for "x" ;

2x/2 = 24/2 ;

to get:

x = 12 .

_____________________________________________

Let us check our answer, by plugging in "12" for "x" ; on EACH side of the original equation; to see if the equation holds true; {that is, to see if each side of the original equation is equal, when "x = 12" } ; as follows:

______________________________________________

3x - 1 = x + 23 ;

Substitute "12" for "x" on each side ;

3(12) - 1 =? (12) + 23 ??

36 - 1 =? 35 ??

35 =? 35?? Yes!
