Hello! answer: 30 and 150

Step-by-step explanation:

supplementary angles add up to 180 degrees

2 × 15 = 30

10 × 15 = 150

150 + 30 = 180 degrees therefore C is the only answer that works in this scenario

and x = 15 just a little more info

In a group of 60 numbers, average of

Arada [10]

Answer:

c. 18

Step-by-step explanation:

First, you would find the total sum of the 60 numbers. The average is always the sum of the numbers divided by the number of numbers.

35*18=630

15*10=150

Now we do not know how many numbers the last group has. However, we can find it out doing 60-35-15 to see how many numbers are left. There would be 10 numbers left

10*30=300

630+150+300=1080

1080/60=18

Hence, the answer is C(18)

What is the sum of an infinite geometric series if the first term is 156 and the common ratio is 2⁄3?

Zanzabum

Answer:

Step-by-step explanation:

We have

$a_1=156,\ r=\dfrac{2}{3}$

If |r| < 1, then the formula of a sum of an infinite geometric sequence is:

$S=\dfrac{a_1}{1-r}$

Substitute:

$S=\dfrac{156}{1-\frac{2}{3}}=\dfrac{156}{\frac{1}{3}}=156\cdot\dfrac{3}{1}=468$
