Calculate the straight line distance AC

Mathematics
1 answer:
kotegsom [21]3 years ago
5 0

Answer:

Cosine Formula :

AC² = AB² + BC² - 2(AB)(BC)cosB

AC² = (40)² + (60)² - 2(40)(60)cos(115°)

AC² = 1600 + 3600 - (4800×(-0.42))

AC² = 5200 + 2016

AC² = 7216

AC = √(7216)

AC = 84.95 km

Hence, the distance of the straight line AC is <u>84.95 km</u>

  • <u>84.95km</u> is the right answer.

25 is what percent of 20?
denis-greek [22]

Answer:

20 is 80% of 25

Step-by-step explanation:

We assume, that the number 25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 25, so we can write it down as 100%=25.

4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.

5. Now we have two simple equations:

1) 100%=25

2) x%=20

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=25/20

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 25

100%/x%=25/20

(100/x)*x=(25/20)*x       - we multiply both sides of the equation by x

100=1.25*x       - we divide both sides of the equation by (1.25) to get x

100/1.25=x

80=x

x=80

50 - 16 ÷ 2 × (12 + 4)
Margaret [11]

Hey there!

50 - 16 ÷ 2 × (12 + 4)

= 50 - 8 × 12 + 4

= 50 - 8 × 16

= 50 - 128

= -78

Therefore, your answer is: -78

Good luck on your assignment and enjoy your day!
