What fraction of a circle does an arc measure of 30 degrees encompass?

Naddika [18.5K]

Answer:

$\frac{1}{12}$

Step-by-step explanation:

A full circle consists of 360°, so we can write the fraction of this arc as $\frac{30}{360}$ , which can be simplified to $\frac{1}{12}$ by dividing the numerator and denominator by 30.

**This content involves simplifying fractions and knowledge on the angle sum of a circle which you may wish to revise. I'm always happy to help!

Answer:

There are approximately 88 adults.

Step-by-step explanation:

The question is:

A fair was attended by 350 people of which two thirds are adolescents and a quarter adults and a fifth are children from 10 to 12 what amount corresponds to adults .

Solution:

Total number of people attending the fair is, N = 350.

The proportion of adults is: P (Adults) = p = 0.25.

Compute the number of adults in the fair as follows:

$\text{Number of adults in the fair}=N\times p$

$=350\times 0.25\\\\=87.5\\\\\approx 88$

Thus, there are approximately 88 adults.

Show and explain how replacing one equation by the sum of that equation and a multiple of the other produces a system with the s

My name is Ann [436]

First, let's multiply the first equation by two on the both sides:
8x + 7y = 39 /2
⇒ 16x + 14y = 78

Now, the system is:
16x + 14y = 78
4x – 14y = –68

After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2

y can be calculated by replacin the x:
8x + 7y = 39
⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
