Answer:
Step-by-step explanation:
Use trigonometry
<u>Let the height of the cloud be x, then we have:</u>
- tan 35° = x/525
- x = 525 tan 35°
- x = 367.6 (rounded)
The height of the cloud layer is 367.6 m
Answer:
10c ≥ 150
At least 15 cars (or c ≥ 15)
Step-by-step explanation:
If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.
This equation can be used to express the situation:
10c ≥ 150
<em>To solve you divide the 10 from both sides of the inequality to get.</em>
c ≥ 15
Answer:
1/36
Step-by-step explanation:
4*36=144
144/12=12
The answer is 40°
i will tell you how,
Total angle sum of any triangle is 180°
∠A + ∠B + ∠E = 180°
70° + 80° + ∠E = 180°
solve for ∠E
∠E = 30°
Now solve use ∠BDE,
∠B + ∠D + ∠E = 180°
20° + 90° + 30° + x = 180° (in triangle DEB, ∠E = 30 + x ) (∠D is 90°)
solve for x
there fore, x = 40°
3/4 of 10 would = $7.5 which would be your answer.
