At the equator earth's surface moves about 4000 kilometers per day.

1 answer:

8 0

A. There are 24 hours in a day, so we have to divide the speed by 24, so we get 166.67

b. Now, to get it in metres per minute, we have to multiply by 1000 (to convert kilometres to metres), and divide by 60 (to convert hours to minutes)

So, we get 2777.78 metres/minute

We have 50 video gamers who share information about their favorite games. 20 people say that Borderlands II is their favorite ga

stealth61 [152]

Answer:

2 people

Step-by-step explanation:

Total number of people (n) = 50

Borderlands II (B) = 20

Fortnite (F) = 33

Minecraft (M) = 19

Borderlands and Fortnite (B&F) = 15

Borderlands and Minecraft (B&M)= 10

All games (B&M&F) = 5

The number of people that claimed more than one game as their favorite (X) is given by:

$X=M+B+F-n\\X=19+20+33-50\\X=22\ people$

Those people can be divided in B&F only, B&M only, M&F only and B&M&F:

$X=(B\&M-B\&M\&F)+(B\&F-B\&M\&F)+(M\&F-B\&M\&F)+B\&M\&F\\X=B\&M+B\&F+M\&F-2*B\&M\&F\\22=10+15+M\&F-2*5\\M\&F=7\ people$

7 people claimed that Minecraft and Fortnite were their favorites however, 5 of those people claimed all of the games as their favorite. Therefore, only 2 people declared Minecraft and Fortnite (exclusively) as their favorites.

If there are 7 bolts in a widget and 6 widgets in an appliance, how many bolts are in 20 appliances?

sweet [91]

A single appliance has 6 widgets, and a widget has 7 bolts. Therefore, you need to multiply 6 by 7 to find the number of bolts in a single appliance.

6 x 7 = 42

Now that you know the number of bolts in an appliance, you can find the number of bolts in 20 appliances by multiplying 42 by 20.

42 x 20 = 840

Hence, there are 840 bolts in 20 appliances.
