Answer:

\bf \large 20 \: inches

Step-by-step explanation:

<h2>Given that :</h2>

  • The radius of a circle is 2.9 in.

<h2>to find :</h2>

  • Find the circumference to the nearest tenth.

<h2>formulas used :</h2>

  • circumference = 2 × π × r

where,

  • π = 22/7
  • r = 2•9 inches

<h2>explanation :</h2>

⟼ c = 2πr

⟼ c = 2 × 22/7 × 2•9 inches

⟼ c = 2 × 3•14 × 2•9 inches

⟼ c = 6•28 × 2•9 inches

⟼ c = 18•21 inches.

<h2>Round to the nearest tenth :</h2>

⟼ c = 18•21 inches

⟼ c = 20 inches

∴ circle circumference is 20 inches .

BRAINLIEST &amp; 25 POINTS PLEASE HELP URGENT DUE IN 10 MINUTES.
Cerrena [4.2K]

Answer:

C) 24 adults

Step-by-step explanation:

Let A be the number of adults and C be the number of children.

If a ticket costs $8 per adult, we can express this as 8A

If a ticket costs $5 per child, we can express this as 5C

Combining the two expressions, we can write 8A+5C=272 as our first equation since the total amount of money collected is $272.

Our second equation would be A+C=40 since there are 40 people.

Now, we can take the second equation and write it as C=40-A so we can substitute the value of C into the first equation as 40-A so we only have to deal with one variable, the amount of adults that went to the theater.

The first equation now becomes 8A+5(40-A)=272 and is much easier to solve:

8A+5(40-A)=272

8A+200-5A=272

3A+200=272

3A=72

A=24

Therefore, there are 24 adults

How is the answer 35? How do I get it?
vlabodo [156]
I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.
