Answer:
a. false
b. true
c. true
d. true
e. false
Step-by-step explanation:
a. False. The "unit rate" is 19.75 gallons per minute. The "unit" of a "unit rate" is in the denominator. Here, the denominator of the rate is 1 minute.
__
b. True. A graph of a proportional relationship is a straight line through the origin.
__
c. True. In 5 minutes, the water in the pool will increase by 98.75 gallons, about 100 gallons.
__
d. True. The ratio of a y-value to an x-value will always be 19.75. That is the meaning of this proportional relationship.
__
e. False. The points (8, 158) or (7.5949, 150) will be on the graph. The point (8, 150) will not.
Answer:
1680 words.
Step-by-step explanation:
There are 60 minutes in an hour. So all you need to do it 560 + 560 + 560.
I say this because he types 560 word in 20 minutes..20+20+20 is 60 so that means you have to add 560, 3 times as well.
Hope this helped! :)

As we know, slope (m) is equal to tan θ for a straight line :


So, we can say that it's a positive constant slope
Answer:
1.07328
Step-by-step explanation:
223.6 x 0.0048=1.07328
I know its one of the congruent ones, as one is for sure a 90 degree angle, on top of an 180 degree angle, which by law of supplementary angles makes the other one 90 degrees. Not sure on the postulate, maybe someone else can help with that.
