You need to make the fractions into improper fractions with the same denometer. 3 4/7 to an improper fraction is 25/7 and 3 1/4 is 13/4. Now get common denometers, in going to choose 28. 100/28 is the same as 25/7 and 91/28 is the same as 13/4. Now subtract 100/28 and 91/28 and you get 9/28. So you need to add 9/28 of a cup.

An investment of $900 earns 6% annual interest and is compounded semi-annually. Write an equation
nalin [4]

Answer:

A=900(1+\frac{0.06}{2})^{2(t)}

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

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

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

First, change 6% into a decimal:

6% -> \frac{6}{100} -> 0.06

Since the interest is compounded semi-annually, we will use 2 for n. Lets plug in the values now and your equation will be:

A=900(1+\frac{0.06}{2})^{2(t)}

Karolina [17]

Answer:

  [0, 7]

Step-by-step explanation:

We want the height to be greater than or equal to 32 ft, so ...

  704 +16t -16t^2 ≥ 32

  t^2 -t -42 ≤ 0 . . . . . . . . . . . subtract 32, divide by -16

  (t -7)(t +6) ≤ 0

This inequality will be true for values of t between -6 and +7. Since we're only concerned with times t ≥ 0, the appropriate solution interval is ...

  0 ≤ t ≤ 7 . . . . [0, 7] in interval notation
