Answer:

223.07

Step-by-step explanation:

Hey There!

So the first step of this problem is to find the equation for the area of a parallelogram and the area of a circle

The area of a parallelogram is equal to bh

base x height

the base is 20 and the height is 15

20x15=300

Now we want to find the equation for area of a circle

to find the area of the circle we use the formula A = pi xr^{2}

A = π x radius²

the radius is the diameter divide by 2

14/2=7 so the radius is 7

now we just plug 7 into the area of a circle formula

7²=49

49x3.14=153.86

But because it is a semi circle we divide by 2

153.86/2=76.93

Now to find the area of the object we subtract 76.93 from 300

300-76.93=223.07

Therefore the area of that object is 223.07

What is the force of gravity (in Newtons) acting between the Earth and a 100-kg person who is on board the International Space S
ratelena [41]

Answer:

f_{G}=317877.55 N = 317.8 kN

Step-by-step explanation:

f_{G}= (G*m_{1}*m_{2})/r^{2}  \\Where:\\f_{G}= force  of  gravity\\G=gravitational constant= 6.6x10^{-11}m^{3}kg^{-1}s^{-2}\\ m_{1}= earth mass = 5.9x10^{24}kg\\m_{2}=person mass = 100kg\\r= distance between the bodies=350km= 350 000 m

mr Goodwill [35]

Answer:

A. 0.2

Step-by-step explanation:

First make the table.

                                          <u>10-grade</u>  <u>11-grade</u>  <u>12-grade</u>  <u>Total</u>

<u>Woodson high school </u>    |     110     |     120    |      80     |   310   |

<u>Valley high school </u>          |     180    |     150    |     120     | 450   |

<u>Riverside high school </u>     |     160    |     140    |     200    | 500   |

<u>Total </u>                                 |     450   |     410    |     400    | 1260 |

Question: In decimal form, to the nearest tenth, what is the probability that a randomly selected riverside high school student is in twelfth grade?

First, find 12-grade and riverside high school number. 200. Take the total lined up with total number, which is 1260, and divide 200 divided by 1260.

200/1260=0.2

The answer is 0.2.

Hope this helps!

If not, I am sorry.
