Kristina needs to mix a 20% alcohol solution with a 60% alcohol solution to create 200 milliliters of a 34% solution. How many milliliters of each solution must Kristina use?
Answer:
20% alc: 135 mL
60% alc: 65 mL
Explanation:
Table:
20% alc / x / (.2)(x)
60% alc / 200-x / .6(200-x)
34% alc. / 200 / (.34)(200)
Equation for 60% alc: .6(200-x) = (.34)(200) + (.2)(x)
Equation for 20% alc: (.2)(x) + .6(200-x) = (.34)(200)
Final:
20% alc: 135 mL
60% alc: 65 mL

In the revolutionary army, muskets, x, cost $6 and bullets, y, cost $2. The army only have $600 as a nation. what equation can we use to show how many muskets and bullets we can afford if we have to spend all of our money.
A) 600x+ 2y=6
B) 6x+2y=600
C) 6+2= xy
D) 2x+ 6y=600
Please help!
Answer:
B
Step-by-step explanation:
Using the equation on option B, we would have to multiply the cost, then the quantity needed of muskets and bullets. So B is the only option on which you have to find out how many of each the Army can afford.
Hopefully this helps! :)

[tex]\sqrt{27} = \sqrt{9}[/tex] ×[tex]\sqrt{3}[/tex] = 3 × [tex]\sqrt{3}[/tex] = [tex]3\sqrt{3}[/tex]
So then
[tex]5\sqrt{27} = 5[/tex] ×[tex]3\sqrt{3}[/tex] = [tex]15\sqrt{3[/tex]

1. Solve the system of equations by substitution:
y = x - 2
4x – 3y = 11
Answer:
x = 5
y = 3
Step-by-step explanation:
y = x - 2
4x - 3y = 11
substitute y in the second equation with x - 2
4x - 3(x - 2) = 11
open the parenthesis
4x - 3x + 6 = 11
x + 6 = 11
subtract 6 from both sides of the equation
x + 6 - 6 = 11 - 6
x = 5
now substitute x for 5 in the original equation.
y = x - 2
y = 5 - 2
y = 3
find the sum 9.33 + 48.4

Find the simple interest and the total amount after two years.
Principal = 2500=2500equals, 2500 rupees
Annual rate of interest = 9 \%=9%equals, 9, percent
Total interest ==equals
rupees
Total amount ==equals
rupees
Answer:
450
2,950
thats the answer
450 is the total interest amount and 2950 is the total amount.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the simple interest, we can use the formula:
A = P(1 + rt)
Now we can simply substitute the values given in the formula.
Before anything, it is a good practice to define the values of each variable.
P = 2,500
r = 9% or 0.09
t = 2
0.09×2500=225
225 is the interest for one year
450 is the total interest for two years.
Now we proceed to use the values in the formula to find total amount.
A=P(1+rt)
A = 2,500(1 + (0.09 × 2))
A = 2,500(1 + 0.18)
A = 2,500( 1.18 )
A = 2,950.00 Rupees
Hence, 450 is the total interest amount and 2950 is the total amount.

At a local pumpkin patch you can pick your own pumpkins. There is a $5 charge to enter the patch and then a $0.25 charge per pound of pumpkin. Let p
represent the weight of the pumpkin you choose and C(p)
represent the total cost of the pumpkin in terms of the weight of the pumpkin. Equation, in function notation:
Answer:
C(p) = 0.25p + 5
Step-by-step explanation:
$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.
m = slope, b = y-intercept
C(p) = mp + b
C(p) = 0.25p + 5
