Thomas invests $50,000 in an account that compounds interest continuously and earns 15%. How long will it take for his money to

WARRIOR [948]

Answer:

It will take about 7.3 years for his money to triple.

Step-by-step explanation:

Identify the variables in the formula.

A = 150,000

P = 50,000

r = 0.15

t = ?

A = Pe^rt

Substitute the values into the formula.

150,000 = 50,000e^0.15*t

Solve for t. Divide each side by 50,000.

3 = e^0.15*t

Take the natural log of each side.

ln 3 = ln e^0.15*t

Use the power property and then simplify.

ln 3 = 0.15*t ln e

ln 3 = 0.15-t

Divide each side by 0.15.

(ln 3) /(0.15) = t

Approximate the answer.

t ≈ 7.3

The football coach bought enough sports mix to make 60 L of a sports drink.

Ilya [14]

the coach makes a total volume of 60 L of a sports drink

we have to find the number of cups he can fill with the drink

1 cup is equivalent to 0.5 pints

so we have to first convert L to pints

1 L = 2.11 pt

then 60 L = 126.6 pt

the volume of sports drink made is 126.6 pt

so 0.5 pt make - 1 cup

then 126.6 pt make - 1 / 0.5 x 126.6 = 253.2 cups

he can make 253 full cups and 0.2 of a cup

answer is 253.2 cups

To celebrate the first day of winter, Lin was putting stickers on some of the lockers. There are 100 lockers along one side of h

loris [4]

Answer:

24, 48, 72, 96

Step-by-step explanation:

Least Common Multiple (LCM)

It's the smallest positive number that is a multiple of two or more numbers. For example, let's find the LCM of 15 and 25:

Multiples of 15: 15,30,45,60,75,90,...

Multiples of 25: 25,50,75,100,...

Note 75 is a common multiple of both and is also the smallest possible.

Lin puts a snowflake sticker every 6 lockers and a snowman sticker every 8 lockers. To find the lockers where both stickers are places, we must find the LCM of 6 and 8:

6 = 2*3

8 = 2*2*2

Multiplying the common factors the maximum number of times it appears:

LCM = 2*2*2*3 = 24

Thus, every 24 lockers there are two stickers until Lin reaches the last 100th locker along the halfway.

The sequence of lockers is:

24, 48, 72, 96
