The equation for finding the area of one triangle is A=1/2(B)(H)
because we have two triangles, we do not need to divide the answer by two.
That being said, 8 times 12 is 96.
By installing a sprinkler for every 10 sq ft. of land we divide that by 10 and get 9.6
Because the decimal value is above 5, my answer would be that you need 10 sprinklers.
Answer: Yes the estimate is very close
Step-by-step explanation:
Multiply 4.9 x 7 then Multiply 6.4 x 7
if 35.7 is in between these 2 numbers this is correct
Answers:you wrote it wrong so I can’t understand
Answer:
700 -1 -200
75 1 5000
Step-by-step explanation:
1. the rule for the required matrix is:
![\left[\begin{array}{ccc}x_1;y_1;a\\x_2;y_2;b\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx_1%3By_1%3Ba%5C%5Cx_2%3By_2%3Bb%5Cend%7Barray%7D%5Cright%5D)
2. if to re-write the given equations, then:
700x-y= -200 and 75x+y=5000.
3. Finally, the answer is:
column№1 | column№2 | column№3
==============+===========+=============
row№1 700 | -1 | -200
row№2 75 | 1 | 5000
