a = amount (in oz) of solution A
b = amount of solution B
The scientist wants a mixture of 110 oz, so
a + b = 110
Solution A consists of 65% salt, so each ounce of solution A contributes 0.65 oz of salt; similarly, each ounce of B contributes 0.9 oz. The mixture is supposed to consist of 75% salt, which amounts to 0.75 * (110 oz) = 82.5 oz of salt. So
0.65 a + 0.9 b = 82.5
Solve for a and b:
b = 110 - a
0.65 a + 0.9 (110 - a) = 82.5
0.65 a + 99 - 0.9 a = 82.5
0.25 a = 16.5
a = 66 ==> b = 44
Answer:
6⁴ there i hope this helps dude
Step-by-step explanation:
Answer:
okay so I think its, horizontal shift right 2 and a vertical shift down 1
Step-by-step explanation:
so x says + 2 so right 2 and y says -y so down 1..?
I'm kinda rusty tho so yeah
Answer: y= 1.5x-6
Step-by-step explanation:
1) Find the slope by using change in y over change in x: 
2) Then use the y intercept from the given: -6
3) create an equation in slope intercept form using those factors: y= 1.5x-6
Answer:
sup have you googled it?
Step-by-step explanation:
Mass of elephant/mass of ant = 8x10^6/4x10^-3 = 2x10^9. Therefore, mass of elephant = 2x10^9 times mass of ant.
