Answer:
Step-by-step explanation:
<u>Surface area:</u>
- S = 2(lw + lh + wh) + 2πrh
- S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)
<u>Volume:</u>
- V = lwh + πr²h
- V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)
Answer:
two-fifths over two-sevenths equals one and two-fifths miles per hour .

Answer:
a) Infinite solutions
b) No solutions
Step-by-step explanation:
First, know the following:
If the graphs intersect, there's only one solution.
If the graphs are parallel, there are no solutions.
If the graphs are the exact same line, there are infinite solutions.
For a):
Change the first equation into a linear one.
Change the second equation into a linear one.
- 4x+6y=12
- 6y=-4x+12
Boom. You have two equations which are equal. As stated above, graphs on the exact same line have infinite solutions.
For b)
They are already in linear form so hurray.
These lines are parallel since they have the SAME slope but a different y-intercept. As stated above, parallel lines have no solutions.
