Answer:
25
Step-by-step explanation:
that what i got
bearing in mind that there are 90 feet between each base in a baseball diamond, so the total perimeter of it will be 90*4 = 360, one third of that is 360/3 = 120.
So Jones went 120 feet first and then another and so on, check the picture below.
using those values, can get the length of those sides, using the pythagorean theorem.
now, we can plug those values in the Heron's Area Formula to get its area.
Answer: (x) =
Step-by-step explanation:
f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes
y = 9x - 8 , then make x , the subject of the formula ,
9x = y + 8
x =
Finally , replace x , with (x) and y with x , so we have
(x) =
Let's eliminate the variable x first. To do this, multiply the first row of this system by 5 and mult. the second row by -7:
7x-5y=14 => 35x - 25y = 70
5x+7y=64 => -35x - 49y = -448
-------------------------
- 74y = - 378. Then y = 378/74 = 5.11.
Subbing 5.11 for y in the first equation, we get: 7x - 5(5.11) = 14. Then:
7x = 14+25.55 = 39.54. Dividing both sides by 7: x = 39.54/7 = 2.71
The solution is (2.71, 5.11). If this does not agree with any of your answer choices, please double check to ensure that you've copied down the original problem correctly.
