The resulting equation 75 = 75 is an identity; this tells that the two equations of the system are equivalent, this is they both represent the same function. So, Lian can conclude that (option c) both gyms charge the same monthly rate and the same membership fee<span>.</span>
Answer:
0.4 l of purple sand
Step-by-step explanation:
<u>Volume to be filled in:</u>
<u>Red sand</u>
<u>Blue sand</u>
- 35 centiliters = 35*10 ml = 350 ml
<u>Yellow sand</u>
- 2.5 deciliters = 2.5*100 ml = 250 ml
<u>Total volume filled:</u>
- 1000 + 350 + 250 = 1600 ml
<u>Purple sand needed:</u>
- 2000 - 1600 = 400 ml = 0.4 l
<u>Answer is</u> 0.4 l of purple sand required
A, expect the second term (2xy) should be just 2y
Answer:
Step-by-step explanation:
The graph is a nonlinear graph.
The hang time is 3 seconds.
The h- coordinate of the top of the bump is about 11 m, so the maximum height is 11 m after rounding to the nearest meter.
For t between 0 and 1.5, the height is increasing.
I hope this helps. I found it on Khan Academy.
Answer:
Step-by-step explanation:
Let
y -----> gallons of water remaining in the barrel
x-----> number of minutes elapsed
we know that
Water leaks out of the barrel at a rate of 1 gallon every 10 minutes
so

The linear equation that represent this situation is
The graph in the attached figure
