N/10 = 29/2
n = 290/2
n = 145
Answer:
Step-by-step explanation:
We have been given a graph of similar triangles. We are asked to find the value of x.
Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.
Upon cross multiplying our equation we will get,
Upon distributing 4 we will get,
Let us subtract 12 from both sides of our equation.
Upon dividing both sides of our equation by 4 we will get,
Therefore, the value of x will be 12.
Answer:
6
Step-by-step explanation:
The length form -1 to 2 is 3
The length from -3 to 2 is 5
√3²+5² = √9+25 =√36=6
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
