this is what I need help with​

Answer:

m angle BCA =48 degrees

m angle ABC =70 degrees

m angle BAC=62 degrees

m angle BCD=132 degrees

Step-by-step explanation:

First you know that both interior angles have to equal the exterior angles (sorry I forgot what the name of the property). This means that the equation will be 6x-8+4x+10=12x-24. Simplify this to get 10x-2=12x-24. Simplify again to get 2x=26. Divide each side by 2 to get x=13. Now that you know x is equal to 13, you should plug x into angle ABC, BAC, and BCD. When you finish, angle ABC should be 70 degrees, angle BAC should be 62, and BCD should be 132.  To find angle BCA, you know that angle ABC is 70 degrees and BAC is 62 degrees. Every triangle has to equal 180 degrees so the equation should be 180-70-62 which is equal to 48. Therefore, m angle BCA =48 degrees, m angle ABC =70 degrees, m angle BAC=62 degrees, and m angle BCD=132 degrees. With this you can mark the correct choices.

Hope this helps you

Answer:

x=4.8

This here you use Pythagorean Theorem.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is c. And the two legs are a and b.

So it'd be 11^2+x^2=12^2

121+x^2=144

Subtract 121 from both sides.

x^2=23

Then take the √ of x^2 and 23

So √x^2=√23

x=4.8

Answer:

7/13

Step-by-step explanation:

The difference that is closest to zero will indicate the fraction that is closest to 1/2. Since 1/26 is closest to zero, 7/13 is closest to 1/2.

We cannot exactly see to well, I recommend you do windows key + shift + x or something similar in order to take a built in screenshot.

IF THE INEQUALITY SIGN ON THE POINT (7,0) IS SOMETHING LIKE "O" THEN THE RANGE IS Y<0

So the range is everything below 0.

IF THE INEQUALITY SIGN IS A DOT INSTEAD OF AN O, THEN IT IS

Y≤0

The domain should be 7, because it never strays off of the x-value of 7.

Answer:

$1.30

Step-by-step explanation:

What you do is add the original 65 cents to the additional 65 cents that were shown to get 130. Since it's more than 100 you make it into dollars, so the final answer is $1.30.

Answer:

$1.30

Step-by-step explanation:

You need to know how coins look like. The middle one is a quarter and the other four are dimes. We know that quarters are worth 25 cents and dimes are worth 10 cents. Because there are 4 dimes, you do 4x10 which is equal to 40. We know that there is only one quarter so we do 40+25 which is equal to 65. Therefore, the tip is 65 cents Then, you add 65 cents to 65 cents again because Faaz had already put 65 cents there. 65+65 is equal to 130. 130 is equal to 1 dollar and 30 cents. Therefore, the tip is $1.30

Answer:

SA = 270 ft²

Step-by-step explanation:

SA = 2(12×5)/2 + (7×5) + (13×7) + (12×7)

SA = (12×5) + (7×5) + (13×7) + (12×7)

SA = 60 + 35 + 91 + 84

SA = 270 ft²

Answer:

Upper Control Limit = 6.03 oz

Lower Control Limit = 5.97 oz

Step-by-step explanation:

Given - A process that makes chocolate candy bars has an output that is normally distributed with a mean of 6 oz. and a standard deviation of .01 oz.

To find - Determine three sigma control limits for an x-bar (mean) chart assuming a sample size of 10.

Proof -

Given that,

μ = 6

σ = 0.01

Z value for 3 sigma process = 3

Now,

Control limits are - μ ± Zσ

Now,

Upper Control limit (UCL) = μ + Zσ

And

Lower Control limit (LCL) = μ - Zσ

Now,

UCL = 6 + 3( 0.01 )

        = 6 + 0.03

       = 6.03

⇒UCL =6.03 oz

Now,

LCL = 6 - 3( 0.01)

      = 6 - (0.03)

      = 6 - 0.03

      = 5.97

⇒LCL =5.97 oz

∴ we get

Upper Control Limit = 6.03 oz

Lower Control Limit = 5.97 oz
