Ryan is a construction worker and is about to put a roof on a new house. He has to measure the front of the roof which is in the shape of a triangle. He finds out the height of the triangle is 12ft and the base of the triangle is 24 feet. How many square feet of wood does he need to purchase to cover the front of the roof?

Answers

Answer 1

Area of the triangle=1/2*base*height

height=12ft

base=24 ft

1/2*12*24

=144sq.ft is the area

He needs to purchase 144 sq.ft of wood to cover the front roof

Which of the following is the correct input-output table for the function? Y=6x+5

Answers

Answer:

The answer is table b.

Step-by-step explanation:

To solve this question,  you can mentally calculate each value of each table, until you come to a wrong one. When you do, move on. To give an example:

Table a:

x input value: 1

y output value: 12

y true output value: 11

I did this by substituting the value of x in the equation given, so:

y = 6(1) + 5 = 11

Simply do this in your mind for each value, and you'll get your answer if every value in the table is correct!

Answer:

D. 74⁻⁶ (74^-6)

Step-by-step explanation:

Looking at the expression, I remember the following: 1 over an exponent (as a fraction) is the same thing as a negative exponent. None of these answers involve an exponent except for D (although A does involve a negative number). So D, which is 74⁻⁶, is the answer here.

Part D

What do the measures of angles BDA and BEA and the fact that AD and AE are radii of circle A tell us about BD and BE



Font Sizes

Answers

Answer:

BD and BE are tangents to the circle

Step-by-step explanation:

Given

See attachment

Required

What does BD and BE represent?

From the attachment, we have:

[tex]\angle BDA = 90^\circ[/tex]

[tex]\angle BEA = 90^\circ[/tex]

[tex]Radii = AD\ and\ AE[/tex]

The measure of angles between a tangent and the radius of a circle is always [tex]90^\circ\\[/tex]

So, because [tex]\angle BDA = 90^\circ[/tex] and AD is a radius, then BD is a tangent to circle.

Similarly,; [tex]\angle BEA = 90^\circ[/tex] and AE being a radius implies that BE is a tangent to circle.

-3x2 - 16x + 12

-3x2 - 16x + 12 =

Answers

Answer: −(3x−2)(x+6)

Step-by-step explanation:

We know it's factored because...

−(3x−2)(x+6)

If we multiply, then we get what we started with.

-3x * x = -3x^2

2 * x = 2x

-3x * 6 = -18x

2 * 6 = 12

-3x^2 - 18x + 2x + 12

-3x^2 - 16x + 12

-96x + 12 that’s it;)

Answer:

[tex]x=44[/tex]

m∠1=118°

m∠2=62°

Step-by-step explanation:

Part A: They are supplementary angles, so

[tex]2x+30+62=180[/tex]

Simplify like terms,

[tex]2x+92=180[/tex]

We subtract 92,

[tex]2x=88[/tex]

Divide by 2,

[tex]x=44[/tex]

Part B:

[tex]m[/tex]∠[tex]1=2x+30[/tex] because ∠2 is vertical to 2x+30.

Plug in 44 for x,

[tex]m[/tex]∠[tex]1=2(44)+30[/tex]

Simplify,

[tex]m[/tex]∠[tex]1=118[/tex]

[tex]m[/tex]∠[tex]2=62[/tex]° because it is a vertical angle to the 62° angle.

Answer:

Solution given:

2x+30+62=180°[linear pair]

2x=180-92°

x=88/2=44°

Now,

<1=2x+30=2×44+30=118°[vertically opposite angle]

<2=62°[vertically opposite angle]

[vertically opposite angle]
