A chemist has one solution that is 20% alcohol and another that is 60% alcohol.

aleksley [76]

Answer:

solution 1= 40ml

solution 2= 160ml

Step-by-step explanation:

%alcohol= amount of alcohol/total solutionx100

0.52x200=104ml of alcohol present

0.2x L=0.2Lml of alcohol in solution one

0.6 x M=0.6Mml of alcohol in solution two

1st equation

0.2L+0.6M=104ml alcohol

times 10 to get whole

2L+6M=1040ml

2nd

same for this equation

10L+10M=2000ml

10L+10M=2000

2L+6M=1040

elimination method

=20L+20M=4000

=20L+60M=10400

-40M=-6400

M=160ml

2L+6 (160)=1040

2L=1040-960

2L=80

L=40ml

Say you have $14,000 to invest into an investment account. You can either invest your money into an account with a 7% annual int

taurus [48]

Answer:

You should choose an account with a 7% annual interest rate which is compounded quarterly

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

part 1)

we have

$t=15\ years\\ P=\$14,000\\ r=0.07\\n=4$

substitute in the formula above

$A=14,000(1+\frac{0.07}{4})^{4*15}$

$A=14,000(1.0175)^{60}$

$A=\$39,645.43$

part 2)

we have

$t=15\ years\\ P=\$14,000\\ r=0.068\\n=12$

substitute in the formula above

$A=14,000(1+\frac{0.068}{12})^{12*15}$

$A=14,000(1.0057)^{180}$

$A=\$38,713.11$
