Answer:

Elissa needs 4 quarts of paint, or 1 gallon.

Step-by-step explanation:

Elissa's room is in the shape of a rectangular prism.  Assuming that she will only be painting the walls and not the floor or ceiling, you just need to calculate the area of the four walls - front and back and side to side.  Based on the dimensions given, the area of Elissa's front and back walls are 8 ft x 9 ft or 72 ft² for each wall.  Since there are two, we take that area times two: 72 x 2 = 144 ft².

Elissa's side walls are 8 ft x 13 ft or 104 ft² for each wall.  Since there are two, we take this area times two:  104 x 2 = 208 ft².

To find the total area needed to paint, we add all four walls:  144 + 208 = 352 ft².  Since a quart of paint covers 100 ft² and a gallon covers 400 ft², Elissa can either purchase 4 quarts of paint or 1 gallon to paint her bedroom.

Which equation represents the value of x? x=100−y2−−−−−−−√ x=10+y2 x=10−y x=y2+100−−−−−−−√ Right triangle A B C with angle B as
Nostrana [21]

Answer:

Therefore the required value of x,

x=\sqrt{(100-y^{2})}

Step-by-step explanation:

Given:

ΔBC is a Right Angle Triangle at ∠ B = 90°

As ∠ B = 90° , AC will be the Hypotenuse

AC = 10 = Hypotenuse

BC = y = Longer leg ( say )

AB = x = Shorter leg ( say )

To Find :

x = ?

Solution:

In Right Angle Triangle Δ ABC , By Pythagoras Theorem we get

(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}

Substituting the given values we get

10^{2}= x^{2}+y^{2} \\\\x^{2}=100-y^{2} \\\\\textrm{square rooting on both the side we get}\\\\x=\sqrt{(100-y^{2})}\\\therefore x=\sqrt{(100-y^{2})}\ \textrm{ which is the required value of x}

Therefore the required value of x,

x=\sqrt{(100-y^{2})}

Translate this verbal expression into an algebraic equation and solve: thirteen less than twice the sum of a number and six is 4
Vesna [10]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the verbal expression

''Thirteen less than twice the sum of a number and six is 47''.

Let us break down the verbal expression into an algebraic equation

  • Let the number be = n
  • Twice the number n = 2n
  • Sum of twice the number and six = 2n+6
  • Thirteen less than twice the sum of a number and six = 2n+6-13

And finally

Thirteen less than twice the sum of a number and six is 47:

2n+6-13 = 47

Therefore, the equation is:2n+6-13 = 47

Solving the algebraic expression

solving the equation for 'n'

2n+6-13 = 47

2n-7=47

Add 7 to both sides

2n-7+7=47+7

Simplify

2n=54

Divide both sides by 2

\frac{2n}{2}=\frac{54}{2}

Simplify

n=27

Explain the steps to measuring an angle using a protractor. How do you determine an angle’s measurement in degrees?
Margaret [11]
Hello

<span>Place the midpoint of the protractor on the VERTEX of the angle.Line up one side of the angle with the zero line of the protractor (where you see the number 0).<span>Read the degrees where the other side crosses the number scale.

Jason has two bags with 6 tiles each what are the chances that he draws a 2 and a 3 with 1 through 6 tiles
liubo4ka [24]
He has a 1/6 chance.
if there are two of 1-6 tiles each in separate bags, he has a chance (total) of 2/12 of getting a 2 and a . simplify the 2/12 to 1/6 and that is your answer.
