Answer:
50 Students
You can find the number of boys and girls by dividing the total, so there are a total of 20 boys and 30 girls in the choir of 50. The ratio 2 boys : 3 girls means we can divide the chorus into groups.
(3x-9) +(x+19)+x=180
5x+10=180
-10=-10
5x=170
5 = 5
x=34
2x+(2x+10)+x=180
5x+10=180
-10=-10
5x=170
5 = 5
x=34
yes they are similar
Answer:
Step-by-step explanation:
<u>Given function:</u>
The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.
<u>The rate of decrease is </u>
<u>Percent decrease is </u>
X2+16 is the prime <span>polynomial.
x2+16 is the only </span><span>polynomial that couldn't be factored out anymore
x2-36 --> (x-6)(x+6)
