The spray from a lawn sprinkler makes a circle 40 feel in radius. What are the approximate diameter, circumference, and area of the circle of lawn watered

Answers

Answer 1

Answer: Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.

Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.

Circumference = 2 * pi * radius = 80 ft * pi
If we say that pi = 3.14, then:
circumference = 251.2 ft.

Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.

A polygon has an angle sum of 360°, and each angle measures 90°. What is the polygon?

Answers

A polygon has an angle sum of 360°, and each angle measures 90°. Let's find our what is the polygon.
=> 360 degrees polygon with 90 degree measure for each angles.
=> 360 degrees / 90 degrees = 4
Therefore the polygon is a square.

At basketball practice you made 21 out of 80 shots. Which choice is closest to the percentage of shots you made?20%

25%

30%

40%

Answers

Since this is a percentage, all you have to do is divide 21 from 80 and multiply that by 100
21/80 = .2625 * 100 is 26.25

The answer closest to this is 25%, so the answer is 25%

Hope this helped! :D

it is clsest to 25% because it actually is 26.25 %

write the equation of a line with the same slope as y-3=-2(x+1) and a solution of (4,10) in slope intercept form

Answers

Answer:

$y=-2x+18$

Step-by-step explanation:

We start by noticing that the given line: $y-3=-2\,(x+1)$ is given in "point slope" form, where the slope (m) is "-2".

We need therefore another line with same slope (m = -2) and which goes through the point (4, 10), which will make it solution of the line equation.

We can use the general form of a line in "point slope" form with slope "m" , and going through the point $(x_0,y_0)$ on the plane as:

$y-y_0=m\,(x-x_0)$

For our case: m = -2 and $y-y_0=m\,(x-x_0)$ = (4, 10) this becomes:

$y-y_0=m\,(x-x_0)\ny-10=-2\,(x-4)\ny-10=-2x+8\ny=-2x+8+10\ny=-2x+18$

Step-by-step explanation:

15 . 4 * 7 = 28 divide by 2 = 14

16. 2^3 = 8 * 3 = 24 +5 * 4 = 20 , 20 + 24 = 44

17. 5 + 4 = 9 + 2 =11

18. 6 * 2 = 12 and -34 * 2 = -68 - 12 = 56
