Answer:

240 ft^2

Step-by-step explanation:

The rectangular prism has 6 faces. Each two opposite faces have the same area. We need to find the areas of 3 faces that are not opposite faces, add them, and then multiply by two.

Top face:

7 ft by 6 ft

area = LW = 7 ft * 6 ft = 42 ft^2

Right face:

7 ft by 6 ft

area = LW = 7 ft * 6 ft = 42 ft^2

Front face:

6 ft by 6 ft

area = LW = 6 ft * 6 ft = 36 ft^2

Sum of areas of 3 faces:

42 ft^2 + 42 ft^2 + 36 ft^2 = 120 ft^2

Now we double the area to account for the 3 faces that are opposite each one of the three faces whose areas we calculated.

2 * 120 ft^2 = 240 ft^2

Answer: 240 ft^2

Answer:

Step-by-step explanation:

Given,

[tex] {x}^{8} = {( {2}^{2} )}^{4} [/tex]

Since,

[tex] { ({a}^{x} )}^{y} = {a}^{xy} [/tex]

Then,

[tex] = > {x}^{8} = {2}^{2 \times 4} [/tex]

[tex] = > {x}^{8} = {2}^{8} [/tex]

(Since the exponents are same so the bases will be also same)

Therefore,

=> x = 2

As per condition,

[tex] {x}^{2} [/tex]

(Putting value of x = 2)

Answer:

x = 60

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360 degrees.

So if we sum up all the given angles, we would get this equation:

2x + x + 90 + 90 = 360

which simplifies to

3x + 180 = 360

subtract 180 from both sides

3x = 180

divide both sides by 3

x = 60

Answer:

Below!

Step-by-step explanation:

Since all angles in this shape add up to 360, I used this formula to find x

  360 = 90 + 90 + x + 2x

  360 = 180 + 3x

  180 = 3x

Divide both sides by 3

   60 = x

You can check to see if this works

90 + 90 + 60 + 120 = 360

Hope this helps!

Answer:

a. GBC, FCB, DCH

b. FCD+HCD=180

Step-by-step explanation:

A

B

The angles that are congruent to ABE are BCF, DCH, and CBG

Angles FCD and HCD lie on the same straight line. This means that the sum of both angles will sum up to 180degrees since the sum of angle of a straight line is 180degrees (supplementary). Hence the required equation will be:

<FCD + <HCD = 180

An angle is a point where two lines meet or intersect.

The angles that are congruent to ABE are BCF, DCH, and CBG

ABE = BCE (corresponding angle)

Since BCE = DCH (vertically opposite angles), hence:

ABE = DCH (vertically opposite angles)

Also, we can see that DCH = CBG (corresponding angles), hence:

ABE = CBG (corresponding angle)

b) From the given diagram, we can see that angles FCD and HCD lie on the same straight line. This means that the sum of both angles will sum up to 180degrees since the sum of angle of a straight line is 180degrees (supplementary). Hence the required equation will be:

<FCD + <HCD = 180

Answer:

23x + 12y + -4xy^2

Step-by-step explanation:

So lets first expand

3y (-4 x(5x - 3y + y^2)

let's ignore 3y for now

Since 5x - 3y + y^2 can't be simplified, we move on to multiplying each number.

note: Capital X = Multiplying symbol

___________________________________

-4 X 5x, -4 X - 3y, -4 X y^2

= -20x + 12y + -4xy^2

now we bring back the 3x

3x - -20x + 12y + -4xy^2

so now we simplify, by finding like terms

= 23x + 12y + -4xy^2

Answer:

The answer is C

Step-by-step explanation:

Answer:

[tex]{ \bf{ \green{line \: B}}}[/tex]

It's a direct proportionality

Answer:

Step-by-step explanation:

We must use system of equations:

horses = h     chickens = c

horses have 4 legs & chickens have 2 and there are 120 legs total so to set up the first part of the equation...

4h + 2c = 120

They both have only 1 head each and there are 48 heads total so to set up the second part of the equation...

h + c = 48

Now we combine the equations and solve:

4h + 2c = 120

h + c = 48

Now we solve...

4h + 2c = 120

h = 48 - c         (subtract c on both sides to single out h)

--------------------

4(48 - c) + 2c = 120

192 - 4c + 2c = 120

-192                  -192

----------------------------

-2c = -72           (divide both sides by -2)

c = 36

Now we go back and find the value of h...

h = 48 - c

h = 48 - 36

h = 12

So there are 36 chickens & 12 horses!

Answer:

x = -8

Step-by-step explanation:

4x - (x - 4) = - 20

Distribute the minus sign

4x - x +4 = -20

Combine like terms

3x+4 = -20

Subtract 4 from each side

3x+4-4 = -20-4

3x = -24

Divide by 3

3x/3 = -24/3

x = -8

Answer:

x = -8

Step-by-step explanation:

4x - (x - 4) = -20

~Simplify

4x - x + 4

~Subtract 4 to both sides

3x = -24

~Divide 3 to both sides

x = -8

Answer:

B is the answer

Step-by-step explanation:

Answer:

B. y = x^2+7x+10

Step-by-step explanation:

Answer:

(- 3, 2 )

Step-by-step explanation:

Given the 2 equations

x + 3y = 3 → (1)

- 2x + 3y = 12 → (2)

Subtract (1 ) from (2) term by term to eliminate y

- 2x - x + (3y - 3y) = 12 - 3

- 3x = 9 ( divide both sides by - 3 )

x = - 3

Substitute x = - 3 into either of the 2 equations and solve for y

Substituting into (1)

- 3 + 3y = 3 ( add 3 to both sides )

3y = 6 ( divide both sides by 3 )

y = 2

solution is (- 3, 2 )

Answer:

62 is the answer to your question

one quick way to know the answer is to know that the two opposite interior angles has to add up to the outer external angle, so x + 38 = 100

Answer:

B. 62°

Step-by-step explanation:

First, solve the unknown interior angle. Interior angles and exterior angles add up to 180°.

? + 100 = 180

? = 80

The sum of the angles of a triangle is 180°. Form and solve the following equation.

x + 80 + 38 = 180

x + 118 = 180

x = 62

Answer:

<a = 30

<b = 60

<c = 115

Step-by-step explanation:

<a = 30 since they are vertical angles and vertical angles are equal

<a + < b + 90 = 180 since they make a triangle

30 + <b +90 = 180

120 + <b = 180

<b = 180-120

<b = 60

<c + 75 = 180 since they form a straight line

<c = 180-75

<c = 115

Answer:

a=30

b=60

c=105

Step-by-step explanation:

We know a=30 because 30 and a are the same

The middle forms a triangle and triangles are equal to 180

The box indicates that the angle is 90 degrees

180=a+b+90

180=30+90+b

b=60

Angle c is supplementary to 75 so it must equal 180

180=c+75

c=105

Answer:

C. $40,000

Step-by-step explanation:

Basic salary = $500

Expected earning this week = $2,500

Expected commission on appliance sales = $2,500 - $500 = $2,000

% commission = 5% = 0.05

Appliance sales = $2,000/0.05 = $40,000
