A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles. What

e-lub [12.9K]

Answer:

Actual area = 21600 Sq.miles

Step-by-step explanation:

We are given;

length; L = 4 inches

Width; W = 6 inches

The scale of the map; 1 inch for every 30 miles i.e. 1 : 30

Since the scale is 1:30, let's find the find the actual dimensions and then the actual area

For the Length,

Since 1 inch represents 30 miles,

Then, 4 inches = (4 × 30)/1 = 120 miles

For the width;

Since 1 inch represents 30 miles,

Then,6 inches = (6 × 30)/1 = 180 miles

Therefore, the actual dimensions are 120 miles and 180 miles

Now, formula for area of rectangle = length × width

Thus;

Actual area = 120 × 180

Actual area = 21600 Sq.miles

Jada's sister works in a furniture store.

Bingel [31]

Answer:

1) $16.35

2) 75%

3) $245

Step-by-step explanation:

1) Jada earns = $15 per hour

9% increase = 15 * 9/100 = $1.35

Increased Jada's pay = 15+1.35 = $16.35

2) Markup = selling price - cost= $350 - 200= $150

Markup % = $\frac{sale price - cost }{cost}*100$ \

= $\frac{150}{200}*100$ = 75%

3) Jada's sister commission is 3.5% of $7000

= $\frac{3.5}{100}* 7000$

= $245

babunello [35]

Answer:

Step-by-step explanation:

4(5) - 6 = 14

14 is not larger than 22, so 5 is not the solution.

4(8) - 6 = 26

26 is larger than 22, so 8 is the solution
