B) no
c) D: (0, 128) domain is what are the possible numbers that can be put into a function. the reason it is 0 to 128 is because you cant have a negative number in this situation and 128 is the max because thats what you started out with
d) 4 teams
Answer:
14819
Step-by-step explanation:
14 600 x 0.015 = 219
14600 plus 219 = 14819
Answer:
108 °
Step-by-step explanation:
∠DOC = 180° - 112° = 68°
∠DOC = 1/2(arc AB + arc DC)
68 = 1/2(y + 80 + y)
68 = y + 40
y = 28
arc dc = 80 + 28 = 108 °
<h3><u>How to solve this problem?</u></h3>
The way I would solve this problem is by first finding the unit rate, or the rate that the jet plane travels in one minute. Then I would multiply the rate by the number of minutes I want to know how far the jet plane flies; in this case it would be multiplied by 18 minutes.
<h3><u>Finding the unit rate.</u></h3>
Let's start by finding the unit rate. To find the unit rate we would divide the ratio, 450 miles:60 minutes (one hour) by 60 minutes to make the 60 minutes become one minute and 450 miles become 7.5 miles.
450 miles:60 minutes ÷ 60/60
7.5 miles:1 minute
<h3><u>Solving the question.</u></h3>
The unit rate is 7.5 miles per minute. Since we know the jet plane flies 7.5 miles every one minute, we can multiply this amount by 18 minutes to find how many miles the place can fly in 18 minutes.
7.5 miles * 18 minutes = 135 miles
The answer to your question is the jet plane travels 135 miles in 18 minutes.
