Answer: The time taken by both of them if they work together is given by
Step-by-step explanation:
Since we have given that
Time taken by Blake to paint one room = 9 hours
Time taken by Ned to paint one room = 6 hours
Work done by Blake = 
Work done by Ned = 
Total work done by both of them together is given by
So, the time taken by both of them if they work together is given by
I think it’s either 4 or 20
5 x 4 =20
6 x 4 =20
1. She can travel 18 miles. Subtract 35 - 2 (initial fee) to have 33. divide 33 by 1.75 to get 18.85. To check how much her total would be, use inverse operations. 18.85 * 1.75 = 32.9875. 32.9875 + 2 = 34.9875. It is barely under $35 but still in her budget.
2. 20m * $1.75 = $35. $70 - $35 = $35. Yes, she can cover the fare. Samantha has more than needed. She can afford the taxi fare and still have money left for future use.
Answer:
Step-by-step explanation:
Given that,
The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
So, the required angle of elevation of the sun is equal to 
.
If 3 = (b x 3)
C. 1
Substitute b for the answer choices so
9 x 3 = 27
6 x 3 = 18
1 x 3 = 3
0 x 3 = 0
