Answer:
m∠A = 144°, m∠B = 36°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Substitute 4(m∠B) for m∠A.
4(m∠B) + m∠B = 180
5(m∠B) = 180
<u>m∠B = 36°</u>
Substitute 36 for m∠B.
4(36) = m∠A
<u>m∠A = 144°</u>
The fourth term of geometric sequence is 24.
<u>Step-by-step explanation</u>:
- First term of a geometric sequence, a = 3.
- The ratio, r = 2.
- The formula to find nth term is, <em>nth term =</em>
To find the 4th term of the sequence,
Put n=4,
4th term =
⇒
⇒ 3 8
⇒ 24
∴ Fourth term = 24.
The variable x is the weight of the letter and they subtract 1 from that, so adding the 0.50 at the end of the equation would be the cost for a one ounce letter.
The answer is:
A) The cost, in dollars, to mail a one ounce letter
To find the percentage of a number, you take the percent - 5% - and change it to a decimal by moving the percent over 2 times to the left and multiplying it by the number. So...
.05 x 63
= 3.15
Answer: 5% of 63 is 3.15
