Answer:
the answer is 180
Step-by-step explanation:
I hope this helps :-)
I’m pretty sure
8. would be false because BK would be 12 where as DF is 10.8
9. is true
The answer is -125. Get this by taking (-5)(-5)(-5)
X + y = 20 --> eqn 1
The second equation would be the mass balance shown below:
(x)(0.40) + y(0.70) = 20(0.52) --> eqn 2
Rearranging eqn 1,x = 20 - ySubstitute this to eqn 2:
(20 - y)(0.40) + y(0.70) = 20(0.52)Solve for y,y = 8 grams Finally, solve for x.x = 20 - 8 = 12 grams
Therefore, Serena needs 12 grams of the 40% solution and 8 grams of the 70% solution.
Multiply base x height then divide by 2 if finding surface are if finding volume multiple base x height x width and divide by 3
