Your friend says that enough information is giving to prove that x=12. Is your friend correct?

Answers

Answer:

C. Yes, you can prove that x = 12

Step-by-step explanation:

My friend is correct because by the HL Congruence Theorem, ∆MNP is congruent to ∆MKL. The hypotenuse and leg of one right ∆ is congruent to the hypotenuse and corresponding leg of the other right ∆. So, enough information was given to prove that x = 12.

Answer:

x = 4

Step-by-step explanation:

Equation: 3x + 13 = 25

Step 1: Subtract 13 from both sides.

3x + 13 = 25

     - 13   - 13

      3x = 12

Step 2: Divide both sides by 3.

3x   =  12

 x = 4

Answer:

  f(-1) = -1

Step-by-step explanation:

x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...

  f(x) = -2x -3

  f(-1) = -2(-1) -3 = 2 -3

  f(-1) = -1

Kaden, Keith, and Kipp compete in a series of daily 3-way races. For each race, the probability that Kaden wins is 1/6, the probability that Keith wins is 1/2, and the probability that Kipp wins is 1/3. On a day that Kaden doesn't win, what is the probability that Keith beats Kipp?​

Answers

9514 1404 393

Answer:

  3/5

Step-by-step explanation:

Let a, b, c represent the probability of a win by Kaden, Keith, and Kipp, respectively.

  P(bc' | a') = P(a'bc')/P(a')

  P(bc' | a') = (1/2)/(1 -1/6) = (3/6)/(5/6) = 3/5

The probability is 3/5 that Keith beats Kipp when Kaden doesn't win.

Melissa is 13 years old. Becky is 12 years old. Daniel is 10 years old. Melissa, Becky and Daniel share £42 in the ratio of their ages. Becky decided to save a third of her share. How much will Becky have to spend?

Answers

Answer: Becky will have to spend £ 9.6 .

Step-by-step explanation:

The ratio of their ages will be:

Melissa : Becky : Daniel = 13 : 12 : 10

Total amount share = £42

Share of Becky = [tex]\dfrac{12}{12+13+10}\times42[/tex]

[tex]=\dfrac{12}{35}\times42\\\\= 14.4[/tex]

Hence, Becky's share = £14.4

Becky decided to save a third of her share.

Then, Amount she spend = [tex]14.4-\dfrac13 \times 14.4[/tex]

[tex]=14.4-4.8\\=9.6[/tex]

hence, Becky will have to spend £ 9.6 .

6051 was rounded to the nearest one. What is the lower bond ?

Answers

Answer:

6050.5

Step-by-step explanation:

The key to this is "rounded to the nearest one"

If the question was to say "round to the nearest 10" you would do 10÷2 = 5

Always divide by 2

1 ÷2 = 0.5

6051 - 0.5 = 6050.5

If it was upper bond it would be:

6051 + 0 5 = 6051.5
