Answer:
<h2><u><em>
y = 70°</em></u></h2>
Step-by-step explanation:
x = 35° (opposite agles)
y = 180 - 35 - 75
y = 70
-----------------------
check 35 + 75 + 70 = 180°
the answer is good
Answer:
<h3> 0.125 galon of 35% acid solution</h3>
Step-by-step explanation:
0.5 gallon of a 10% acid solution
10%•0.5 = 0.05 gallon of acid in that solution
x gallon of 35% acid solution
35%•x = 0.35x gallons of acid in that solution
0.05 + 0.35x total of gallons of acid in both solutions
(0.5+x) gallons of 15% acid solution
15%(0.5+x) = 0.15(0.5+x) gallons of acid in that solution
the amount of gallons of acid didn't change after mixing, so:
0.05 + 0.35x = 0.15(0.5 + x)
0.05 + 0.35x = 0.075 + 0.15x
0.35x - 0.15x = 0.075 - 0.05
0.2x = 0.025
×5 ×5
x = 0.125
Answer:
E, needs more info to be determined
Step-by-step explanation:
We know that Kai takes 30 minutes round-trip to get to his school.
One way is uphill and the other is downhill.
He travels twice as fast downhill than uphill.
This means that uphill accounts for 20 minutes of the round-trip and downhill accounts for 10 minutes of his trip.
However, even with this information, we do not know how far his school is.
In order to figure out how far away his school is, we would need more information about the speed at which Kai is traveling.
Simply knowing that he travels twice as fast downhill is not enough.
This question could only be solved by knowing how many miles Kai travels uphill or downhill in a given time.
Answer: by multiply until you get your sum
Step-by-step explanation:
Area = Length x Width (A = L x W)
A = 264, W = 11, L = ?
Rewrite the equation to find L. In order to reverse multiplication, you must divide.
L = A / W
L = 264 / 11 = 24 yards
