Height of the tree is 87 ft
Step-by-step explanation:
- Step 1: Find the height of the tree using trigonometric ratio tan.
Angle = 44°, adjacent side = 90 ft
⇒ tan 44° = opposite side/adjacent side
∴ Opposite Side = adjacent side × tan 44°
= 90 × 0.97
= 86.91 ft ≈ 87 ft
⇒ Height of the tree is 87 ft

Step-by-step explanation: In this equation, it's important to understand that the number 5 is the coefficient on the variable M. This just means that -5 "times" M equals -40. So, whenever you see a number next to a variable, it means multiplication.
If we were to solve, we would just divide both sides of the equation by 5. On the left the 5's cancel and on the right, -40 divided by 5 is -8.
To solve this, we would have to get m by itself. Since m is being multiplied by -5, you would have to divide -5 on both sides to get m alone.
-5m=-40
/-5 /-5

(2×17.25)+(2×1)+(2×x)= 40.50
There are 2 girls so we multiply all the charges by 2. Add them together and you'll get 40.50. Now if we solve for x, we will get the amount of the convenience fee.
2×17.25 + 2×1 + 2x = 40.50
34.50 + 2 + 2x = 40.50
36.50 + 2x = 40.50
2x = 40.50 - 36.50
2x = 4
x = 2
Each girl paid a 2 dollar convenience fee.

So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.
Answer:
5.25 mph , for 42 mile she would ride around 8 hours
Step-by-step explanation:
you need to divide the 21 miles by the 4 hours to find how many miles Shelly rode for one hour and that will be your answer ( 5.25 mph)
