A candy bar box is in the shape of a triangular prism. The volume of the box is 1,200 cubic centimeters. A triangular prism is s

Nastasia [14]

The height of the base is 12cm.

The approximate amount of cardboard used to make the candy box is 720 cm².

Given

A candy bar box is in the shape of a triangular prism.

The volume of the box is 1,200 cubic centimeters.

A triangular prism is shown with a base of the triangle labeled 10 cm, sides of the triangles labeled 13 cm, and length of the box equal to 20 cm.

<h3>The volume of the prism;</h3>

The volume of a triangular prism is given by the formula;

$\rm Volume=\dfrac{1}{2} \times length \times width \times height$

Part A: What is the height of the base?

The height of the base is given by;

$\rm Volume=\dfrac{1}{2} \times length \times width \times height\\\\1200=\dfrac{1}{2}\times 20 \times 10 \times Height\\\\Height =\dfrac{1200\times 2}{20 \times 10}\\\\Height =\dfrac{2400}{200}\\\\Height = 12 \ cm$

The height of the base is 12cm.

Part B: What is the approximate amount of cardboard used to make the candy box?

The approximate amount of cardboard used to make the candy box is given by;

$\rm Area = 2 \times length \times width+ length \times width \\\\Area = 2\times 20 \times 10+ 20\times 10\\\\Area = 520+200 \\\\Area = 720$

The approximate amount of cardboard used to make the candy box is 720 cm².

Rewrite the following expression X^9/7

KonstantinChe [14]

Answer:

$x\sqrt[7]{x^{2} }$ (D)

Step-by-step explanation:

Given: $x^{\frac{9}{7} }$

To find: Simplify the given expression

Solution: Simplyfying, we get,

$x^{\frac{9}{7} } =x^{\frac{7}{7} +\frac{2}{7} }$

$=x^{1} *x^{\frac{2}{7} } \\=x*x^{\frac{2}{7} } \\=x=\sqrt[7]{x^{2} }$

Therefore, $x\frac{9}{7}$ can be written as $x\sqrt[7]{x^{2} }$

What is the range of function from y = 2x - 2 with the domain 1,2,3 ?

algol [13]

If the domain of <span>y = 2x - 2 is {1, 2, 3}, then the range has only three values:

2(1)-2=0
2(2)-2=2
2(3)-2=4

The range is {0,2,4}.</span>

Y=-3x-5 <br> y=4x+30<br> PLS HELP ASAP

Dominik [7]

{y,x} = {10,-5}

Step-by-step explanation:

sorry if this dont make sense

solve equation [2] for the variable y

y = 4x +30

plug this in for variable y in equation [1 ]

(4x+30) +3x= -5

solve [1] for the variable x

7x= - 35

x= - 5

by now we know this much

y= 4x+30

x= - 5

use the x value to solve for y

y=4 (-5) + 30 = 10

solution

{y,x} = {10,-5}
