Answer:
B. 840
Step-by-step explanation:
21 is 70% of 30 and 70% of 1,200 is 840.
Answer:
Yes
Step-by-step explanation:
12 divided by 2 = 6, 24 divided by 4 = 6, 36 divded by 6 = 6, 48 divded by 8 = 6, 60 divided by 10 = 6.
All answers have 6 so yes it is proportional.
Answer:
Solve for Y, then use either equation to find X
Step-by-step explanation:
360-275-20=65ratio 3:103x+10x=6513x=65x=55*3=15° and 5*10=50°15° and 50° are the other two angles
<h3>
Answer: Yes it is a function.</h3>
Reason:
There are no repeated x values, so each x input leads to exactly one y output. That's why we have a function.
If we had something like (1,18) and (1,12), then the input x = 1 leading to simultaneous outputs y = 18 and y = 12 would mean we wouldn't have a function.
