The answer would be
40,000
Answer: d = ±10
<u>Step-by-step explanation:</u>
169 = 
+ 
169 = (12)² + 
169 = 144 +
25 =
100 = d²
√100 = √d²
±10 = d
1- 3(-2^2t)-7
2- 12+5=17
3- -10-6= -16
4- 2(-5^3)= -250
I can’t find the first one because of t
Let us determine each of their rates of work:
Since Tiana can clear the field in 3 hours, meaning she can do 1/3 of the work per hour.
In the same way, Jacob can do 1/2 of the work per hour.
Now, what would be the rate of work if they were working together? Let's look at it like this:
Hours to complete the job:
Tiana = 3
Jacob = 2
Together = t
Work done per hour:
Tiana = 1/3
Jacob = 1/2
Together = 1/t
If you add their labor together:
1/3 + 1/2 = 1/t
5/6 = 1/t
t = 6/2 = 1.2
Together, they can clear the field in 1.2 hours.
