9514 1404 393

Answer:

  102

Step-by-step explanation:

The total of ratio units is ...

  6 + 3 + 8 = 17

The difference between the Charlie's ratio units and Adrian's ratio units is ...

  8 - 6 = 2

That is, the total number of ratio units is 17/2 = 8.5 times that difference.

The actual difference is 12 sweets, so the total number of sweets is ...

  8.5 × 12 = 102 . . . . total sweets

On a blueprint of a house, 48 millimeters represents 7 meters. The length of the living room is 60 millimeters on the blueprint.
Pani-rosa [81]
Here is the equation 48/7=60/x, 48÷7=6.8571428571. Now we know that every one meter in real life is equal to 6.8571428571 millimeters so, 60÷6.8571428571= 8.75 meters. The living room is 8.75 meters

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)}
