On the Venn diagram, which would be classified as an IRRATIONAL number?

Mathematics
1 answer:
AnnyKZ [126]2 years ago
5 0

Answer:

The correct answer is B. 2π

Step-by-step explanation:

A rational number is one that can be represented using a fraction and an irrational number cannot be represented using a fraction.

-√4 = -2, which is a rational number

2π is not a rational number (we cannot express pi as a fraction exactly even though there are some close approximations)

2.2121... is also a rational number because it can be expressed as a fraction (21/99, or 7/33 simplified)

√225 is 15, which is a rational number

Therefore, the only irrational option is option B. 2π, which is your answer.

Hope this helps!

A city bus collected $780 in fares on one day.
Brilliant_brown [7]

Answer:

450 people paid the discounted fare and 750 people paid the regular fare.

Step-by-step explanation:

let r be regular fares paid and d be discounted fares paid

Total fares = 0.8r + 0.4d = 780

Since 1200 people paid the fares,

r + d = 1200 = Total people

Rearrange this formula:

r = 1200 - d

Substitute r into Total Fares formula

Total fares = 0.8r + 0.4d

780 = 0.8(1200-d) + 0.4d

780 = 960 - 0.8d + 0.4d

780 = 960 - 0.4d

0.4d = 180

d = 450

Sub d=450 into Total people formula

r + d = 1200 = Total people

r + 450 = 1200

r = 1200-450

r = 750

450 people paid the discounted fare and 750 people paid the regular fare.

You and a friend stand back to back. You run 20 feet forward, then 15 feet to your right. At the same time, your friend runs 16
Stells [14]

Answer:

Distance traveled by the snowball  = 45feet

Step-by-step explanation:

The distance traveled by the snowball = distance of hypothenus for both Right angle triangle

1st pythagoras =

X² = 20² + 15²

X = (20² + 15²)¹/² = 25 feet

2nd pythagoras =

X² = 16² + 12²

X = (16² + 12²)¹/² = 20 feet

Distance traveled by the snowball = 20 + 25 = 45feet
