Answer:

See explanation

Step-by-step explanation:

      Statement                     Reason

1. the diagram shows segment AC with point B on this segment, then

   AB+BC=AC              <u>Segment addition postulate</u>

2. Given AB=2x,\ BC=6x+8,\ AC=32, then

   2x+6x+8=32              <u>Substitution property</u>

3. Simplify the equation as follows

   8x+8=32                      <u>Combine like terms</u>

4. Subtract 8 from both sides

   8x+8-8=32-8\\ \\8x=24          <u>Subtraction property of equality</u>

5. Divide by 8:

   x=3                                <u>Division property of equality</u>

What is the slope of the line with equation y = –3?<br> I have no idea how to do this.
Sergio [31]

Sure you do  !
I'll tell you what it is, and why, and you'll slap your forehead
and call yourself names.

The 'standard'  form of an equation that shows the slope and intercept is

                                      y = (slope) x + (intercept)

<em><u>What if the slope is zero</u> ?</em> 

Then the equation is                y = (0) x + intercept
                                             or
                                                     y = intercept.

Does that look anything like    y = -3  ?

In the triangle, ABC, the measure of ∠A is 30° and the measure of ∠C is 90°. What is the measure of ∠B?
Molodets [167]

Answer:

60°

Step-by-step explanation:

angle A +angle B +angle C = 180

30° +B+90°= 180

120°+B=180°

B=180°-120°

B=60°

Bob discovers a box with 30 identical, used, rechargeable batteries in his attic.
monitta

Answer:

a) All of them are out of charge = 9.31x10⁻¹⁰

b) 20% of them are out of charge = 5.529x10⁻⁴

Step-by-step explanation:

This problem can be modeled as a binomial distribution since

There are n repeated trials and all of them are independent of each other.

There are only two possibilities: battery is out of charge and battery is not out of charge.

The probability of success does not change with trial to trial.

Since it is given that it is equally likely for the battery to be out of charge or not out of charge so probability of success is 50% or 0.50

P = 0.50

1 - P = 0.50

a) All of them are out of charge?

Probability = nCx * P^x * (1 - P)^n-x

Probability = ₃₀C₃₀(0.50)³⁰(0.50)⁰

Probability = 9.31x10⁻¹⁰

b) 20% of them are out of charge?

0.20*30 = 6 batteries are out of charge

Probability =₃₀C₆(0.50)²⁴(0.50)⁶

Probability = 5.529x10⁻⁴
