I need help with letter C, find the area
ElenaW [278]

Answer:

x = 38

Step-by-step explanation:

Here, we can use the area formula A = 0.5(Bh) to solve for x.

In this case, A = 399, B = x, and h = 21

399 = \frac{21}{2} x\\x = \frac{2*399}{21} \\x = 38

Solve this equation for b. (3+2)-b=1
EleoNora [17]

Answer:

b = 4

Step-by-step explanation:

First, 3 + 2 = 5

This can be substituted to 5 - b = 1

Subtract 5 from both sides leaving -b = -4

We don't want be to be negative so we divide the imaginary -1 that's in front of the b from both sides

This leaves b = 4

On a map scale two neighboring towns are 2.4 inches apart. The actual straight line distance between the two towns is 36 miles.
ladessa [460]

Answer:

The scale of the map is 1 inch is <u>15 miles.</u>

Step-by-step explanation:

Given:

Distance of neighboring towns on map = 2.4 inches

Actual Distance of neighboring towns = 36 miles.

We need to find the scale of map;

Solution:

Now we know that;

On map 2.4 inches = 36 miles actual distance.

So on map 1 inch = Actual distance in 1 inch of scaling on map.

By using Unitary method we get;

Actual distance in 1 inch of scaling on map = \frac{36}{2.4} =15\ miles

Hence The scale of the map is 1 inch is <u>15 miles.</u>
