Option D. 17/10 or 1.7 is correct or 1 7/10 is also correct :)
Move the 150 to the left to get x^2+5x-150=0
Then factor to (x+15)(x-10)=0
The roots are -15 and 10
The positive root is 10
Answer: First Box, Fourth Box
Step-by-step explanation: I took the test
Initial fee charged by Joe's canoe = $20
Hourly charge of Joe's canoe = $4
Hourly charge of Callie's canoe = $14
No initial fee is taken by Callie's canoe.
Let us assume the number of hours after which both places charges will be the same = x hours
Then
20 + 4x = 14x
20 = 14x - 4x
20 = 10x
x = 20/10
= 2
So after 2 hours the charges taken by both of them will be the same. I hope the procedure is easy and clear enough for you to understand.
If the values are accurate there will be <span>84 Turkish vultures, 14 bald eagles, 28 northern goshawks, and 49 red-tailed hawks.
Jeff's observation accounted for 25 total birds. 175/25 is 7. Multiply the original values by 7 to get an estimate of the total birds in the sanctuary this year.
