00 x 0.24 = a x 0.40 + ( 700 -a ) x 0.15 = 0.40 a - 0.15 a + 105.00
<span>168.00 = 0.25a + 105.00 </span>
<span>a = 252 </span>

<span>Solution with 15 % ...................700 - 252= 448 liters.........................ans</span>
Answer:
We know that 
and using this identity we have:
And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:
![A= [X | x \in R]](https://tex.z-dn.net/?f=%20A%3D%20%5BX%20%7C%20x%20%5Cin%20R%5D)
Step-by-step explanation:
For this case we have the following equation given:
We know that and using this identity we have:
And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:
Answer:
ok <A is 85°
Step-by-step explanation:
the angle adjacent to 130 is 50 and the angle vertically opposite to 4x-3 is the same thing, their sum, equated to 180 will result in x being 12. put it in the unknown (x) to get <A

Answer:
7.3
Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-5-(-3))² +(1 -8)²) = √((-2)² +(-7)²) = √(4+49) = √53
d ≈ 7.28011 ≈ 7.3 . . . units
XZ ≈ 7.3
