Answer:

8 units

by step explanation:

Since AB and DC are parallel to each other;

Then x + 2x = 180°

3x = 180°

x = 180/3 = 60°

∆ABC = 60° and ∆ ADC = 120°

∆BAD = 60° (adjacent angles of a trapezoid add up to 180°)

As shown in the figure attached, part of line AB is equal to 3 units and part is equal to: (c) units * 2 .

[tex] \frac{c}{5} = \cos(60) = \frac{1}{2} [/tex]

c = 2.5 units

Hence length AB is equal to; 2(2.5) units + 3 units = 8 units

(2+3)^2-16÷2 is equal to 17

Answer:

Step-by-step explanation:

Brackets: 2 + 3 = 5

power: (5)^2 = 25

Divide 25 - 16 ÷2 = 25 -     8

Subtract: 25 - 8 = 17

Actually I think the question should be using brackets. It's hard to tell what to do after the power.

Answer:

  1125

Step-by-step explanation:

The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.

  $5.60n = $6300

  n = 6300/5.6 = 1125

The company should sell 1125 units per month to break even.

Answer:

[tex] |5x + 3| < 23 \\5x + 3 < 23 \\ 5x < 23 - 3 \\ 5x < 20 \\ \frac{5x}{5} < \frac{20}{5} \\ x < 4[/tex]

Answer:

-26/5 < x < 4

Step-by-step explanation:

5x+ 3 = 23

x = 4

5x+3 = -23

5x = -26

x = -26/5

-26/5 < x < 4

Answer:

13x -9

Step-by-step explanation:

4x-1 + 9x-8

Combine like terms

13x -9

Answer:

9x+−8+4x+−1

(9x+4x)+(−8+−1)

13x+−9

Answer:

  182 seconds, or 3 minutes 2 seconds

Step-by-step explanation:

The second lap takes ...

  (50 s)(1 +20%) = (50 s)(1.2) = 60 s

The third lap takes ...

  (60 s)(1.2) = 72 s

The three laps take 50 +60 +72 = 182 seconds, or 3 minutes 2 seconds.

Answer:

868 miles

Step-by-step explanation:

cm to miles ? are you sure you got the problem description right ? because cm are part of the metric system (mm, cm, meters, kilometers), while miles are part of American/ UK systems. and they don't deal with cm.

but ok, so, we will not deal with conversion rates, we will just apply the scale factors.

2.5 cm <-> 620 miles

3.5 cm <-> ? miles

that is determined by the factor to go from 2.5 to 3.5 cm. the same factor then had to be applied to the miles.

2.5 × f = 3.5

f = 3.5 / 2.5 = 7/2 / 5/2 = 7/2 × 2/5 = 7×2 / 2×5 = 7/5

=>

620 × 7/5 = 868 miles

Answer:

Yes, you are adding a negative number = lower temperature. Higher temperature is positive.

30 - 23 = 7 degrees at night.

Step-by-step explanation:

This is because there are 20 women out of 50 people total (30+20 = 50).

So 20/50 = 2/5

This converts to the decimal form 0.4 and the percentage form 40%
