The answers are:

AC = AB + BC

3x+3 = -1+2x+11

3x-2x = -1-3+11

x = 7


AC = 3x+3                   x = 7

AC = 3x7+3

AC = 24


Hope it helps!

AfilCa [17]

Answer:

Q(t) = 4.5(1.013)^{t}

The world population at the beginning of 2019 will be of 7.45 billion people.

Step-by-step explanation:

The world population can be modeled by the following equation.

Q(t) = Q(0)(1+r)^{t}

In which Q(t) is the population in t years after 1980, in billions, Q(0) is the initial population and r is the growth rate.

The world population at the beginning of 1980 was 4.5 billion. Assuming that the population continued to grow at the rate of approximately 1.3%/year.

This means that Q(0) = 4.5, r = 0.013

So

Q(t) = Q(0)(1+r)^{t}

Q(t) = 4.5(1.013)^{t}

What will the world population be at the beginning of 2019 ?

2019 - 1980 = 39. So this is Q(39).

Q(t) = 4.5(1.013)^{t}

Q(39) = 4.5(1.013)^{39} = 7.45

The world population at the beginning of 2019 will be of 7.45 billion people.

Think carefully about the angle relationship the following represents.
lisov135 [29]

Answer:

See below ↓↓↓

Step-by-step explanation:

<u>Subquestion #1</u>

  • These angles form a linear pair
  • They are supplementary, and add up to 180°
  • 2x + 48 = 180
  • 2x = 132
  • <u>x = 66</u>

<u></u>

<u>Subquestion #2</u>

  • These angles are complementary, and add up to 90°
  • 35 + 4x + 7 = 90
  • 4x + 42 = 90
  • 4x = 48
  • <u>x = 12</u>

<u></u>

<u>Subquestion #3</u>

  • As in #1, they are a linear pair, and are supplementary
  • 3x + 54 = 180
  • 3x = 126
  • <u>x = 42</u>
