Answer:

330ft²

Step-by-step explanation:

Area of figure = Area of rectangle + Area of semicircle

= lb + pi r²/2

= 10 x 8 + 3.1 x 4 x 4/2 ( as 8 is diameter)

= 80 ft² + 248 ft²

= 328 ft² => 330ft²

On a map, 1.5 centimeters represents a distance of 45 kilometers. If two points on the map are 0.8 centimeters apart, what is th

Dmitry_Shevchenko [17]

Write a proportion
centimeters / kilometers
1.5 / 45 = 0.8 / x
cross multiply
(1.5 * x ) = (45 * 0.8)
1.5x = 36
divide both sides by 1.5
x = 24

The actual distance between the two points is 24 kilometers.

Hope this helps

what does the slope of -1 tell you about thr relationship between lengths and widths of rectangles with perimeter 24?

NeX [460]

Using linear function concepts, the slope of -1 means that when one of the length/width is increased by 1, the other is decreased by 1.

<h3>What is a linear function?</h3>

A linear function is modeled by:

$y = mx + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0.

In this problem:

The lengths and the widths are interchangeable, that is, either can be considered as the input or as the output.

The slope of -1 means that when the input in increased by 1, the output is decreased by -1, that is, when one of the length/width is increased by 1, the other is decreased by 1.
