Let log5 125 = x

Removing log you get 5^x = 125

Rewrite 125 as 5^3

Now 5^x = 5^3

x = 3

$4750 invested at 10% p.a compounded semiannually for 10 years, calculate the interest

alexgriva [62]

<h3>Answer: $7,853.16</h3>

Work Shown:

A = P*(1+r/n)^(n*t)

A = 4750*(1+0.10/2)^(2*10)

A = 12,603.164099436

A = 12,603.16

That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.

interest = A-P = 12,603.16 - 4,750 = 7,853.16

The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." Jada mixes 24 ml of blue water with 9

cluponka [151]

Answer:Jada will get same shade as Perfect Purple Water

Step-by-step explanation:

STEP 1

To get the right recipe for Perfect purple water, every new mixture must have an equivalent ratio as the ideal mixture

The ideal mixture is given as

8ml blue water and 3 ml red water.

Step 2

Andre mixes 16ml blue water with 9ml red water

$\frac{8ml}{3ml}$ is not equivalent to $\frac{16ml}{9ml}$

Because dividing Andre's mixture by a common value will not give the equivalent ratio of the ideal recipe

$\frac{16ml}{9ml}$ $\frac{/}{/}$ $\frac{3}{3}$ = $\frac{5.3ml}{3ml}$

Jada mixes 24ml blue water with 9ml red water

$\frac{8ml}{3ml}$ is equivalent to $\frac{24ml}{9ml}$

Because dividing Jada's mixture by a common value gives the equivalent ratio of the ideal recipe

$\frac{24ml}{9ml}$ $\frac{/}{/}$ $\frac{3}{3}$ = $\frac{8ml}{3ml}$

This shows that Jada got the right recipe and will get same shade as Perfect Purple Water but in a higher quantity, 3 times the right recipe for Perfect Purple Water
