Can someone tell me how do I solve this. how is the result 2.40
liubo4ka [24]

Step-by-step explanation:

<u>Properties used</u>

  • logₐ a = 1
  • log aᵇ = b log a
  • log ab = log a + log b

See the steps below

  • - log (4*10⁻³) =
  • - (log 4 + log 10⁻³) =        (log 4 ≈ 0.6 rounded)
  • - (0.6 - 3*log 10) =
  • - (0.6 - 3*1) =
  • - (0.6 - 3) =
  • - (- 2.4) =
  • 2.4

A pitcher holds 3/4 gallons of kool-aid. Martin wants to pour equal amounts of kool- aid into 6 smaller cotainers. How much kool
statuscvo [17]

Answer:

\dfrac{1}{8}\ gallons

Step-by-step explanation:

Amount of kool - aid that the pitcher can hold = \frac{3}4 gallons

There are 6 smaller containers in which this kool - aid is to be adjusted.

Also, the volume of the smaller containers is equal to each other i.e. the containers are identical to each other in terms of volume.

To find:

The amount of kool - aid that each container can hold?

Solution:

Volume of all the smaller containers combined = Volume of the kool - aid available

Let the volume of one smaller container = V

V + V + V + V + V + V = \dfrac{3}{4}\ gallons

\Rightarrow 6V = \dfrac{3}{4}\ gallons\\\Rightarrow V = \dfrac{3}{4\times 6 }\ gallons\\\Rightarrow V=\bold{\dfrac{1}{8}\ gallons}

\frac{1}{8}\ gallons of kool - aid is the amount that each smaller can hold.

V125BC [204]

a) The formula for compound interest is:

Total = starting amount x (1 + interest rate)^ number of years

b)

Using the given information you have:

1200 = 500 x (1+0.045)^x where x is the length of time you want to find.

1200 = 500 (1.045)^x

Divide both sides by 500:

2.4 = 1.045^x

Use natural logarithms:

ln(1.045^x) = ln(2.4)

Solve for x:

X = ln(2.4) / ln(1.045)

X = 19.889 years ( Round the answer as needed).
