Work out 1/2 x 7 giving your answer as a mixed number
irga5000 [103]

Answer:

4\frac{1}{2}

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»»  \frac{1}{2} of 7  <u>OR</u>  7 ÷ 2

So, just solve using either one and you’ll get 4.5 or 4\frac{1}{2}. But since the question wants the answer to be a mixed number, then choose 4\frac{1}{2}.

Hope this helps! :)

How long would it take for money to double at 11% interest compounded quarterly?
vlada-n [284]

Answer: Approximately 6.3876 years

When rounding to the nearest whole number, this rounds up to 7 years.

===============================================================

Work Shown:

We'll use the compound interest formula

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

where,

  • A = amount of money after t years
  • P = initial deposit amount or principal
  • r = interest rate in decimal form
  • n = compounding frequency
  • t = number of years

In this case, we know that,

  • A = 2P, since we want the initial amount to double. P can be any positive real number you want and it doesn't affect the answer.
  • r = 0.11
  • n = 4, since we're compounding 4 times a year
  • t = unknown, what we want to solve for

So,

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

2P = P*(1+r/n)^(n*t)

2 = (1+r/n)^(n*t)

2 = (1+0.11/4)^(4*t)

2 = 1.0275^(4t)

Ln(2) = Ln(1.0275^(4t))

Ln(2) = 4t*Ln(1.0275)

4t*Ln(1.0275) = Ln(2)

t = Ln(2)/(4*Ln(1.0275))

t = 6.38758965414661

It takes roughly 6.3876 years for the deposit to double. If you need this to the nearest whole number, then round up to 7. We don't round to 6 because then we would come up short of the goal of doubling the deposit.

Please answer this correctly
wolverine [178]

Answer:

1017.36 square miles

Step-by-step explanation:

Since the diameter of a circle is twice the radius, the radius of this circle is 36/2=18. Since the area of a circle is \pi r^2, the area of this circle is:

3.14 \cdot 18^2 = 1017.36

Hope this helps!
