Jason drew a scale drawing of a city. He used the scale 1 inch : 4 yards. A neighborhood park is 68 yards wide in real life. How

ra1l [238]

Answer:

17 inches

Step-by-step explanation:

The scale is the same at every distance, so ...

$\dfrac{\text{1 in}}{\text{4 yd}}=\dfrac{w}{\text{68 yd}}\\\\\text{(1 in)}\dfrac{\text{68 yd}}{\text{4 yd}}=w \qquad\text{multiply by 68 yd}\\\\\text{17 in}=w$

The park is 17 inches wide on the drawing.

Part C<br> How many cubic blocks are needed to fill the fish tank?

nikklg [1K]

Answer:

$2\frac{2}{3}$ cubic blocks

Step-by-step explanation:

The given parameters are:

$Length = \frac{1}{2}yd$

$Width = 16yd$

$Height =\frac{1}{3}yd$

Required

Number of cubic blocks to fill the tank

To do this, we simply calculate the volume of the tank by:

$Volume = Length * Width * Height$

This gives:

$Volume = \frac{1}{2} * 16 * \frac{1}{3}$

$Volume = \frac{16}{6}$

Simplify

$Volume = \frac{8}{3}$

Express as mixed numbers

$Volume = 2\frac{2}{3}yd^3$

A light-year is 5.9 x 10^12 miles. A mile is approximately 6.34 x 10^4 inches. About how many inches are in a light-year? Write

NeTakaya

The answer would be 3.7406 × 10^17. Because when multiplying the constant you would get 37.406 and then you add the exponent and add one more since only one decimal can be over the decimal.
