The y answers would be 11, 8, 5, 2, -1.
To find these parts of the table, we simply put the x value in for x and solve for y. The first two are done for you below.
WHEN x = -2
y = -3x + 5
y = -3(-2) + 5
y = 6 + 5
y = 11
WHEN x = -1
y = -3x + 5
y = -3(-1) + 5
y = 3 + 5
y = 8
Time taken to fill the bathtub is 8 min
time taken to drain the bathtub is 12 min
fraction of bathtub filled in 1 hour=1/8
fraction of bathtub drained in 1 hour=1/12
fraction that will be filled in a minute given that both taps are opened at he same time:
1/8-1/12
=1/24
thus time taken for the bathtub to be filled is 24 min
Answer:
c. 113
Step-by-step explanation:
<span>Old Surface Area = 202 ft^2
New Surface Area = 1818 ft^2
Notice we have this ratio:
(new area)/(old area) = 1818/202 = 9
and how 3^2 = 9. This is no coincidence.
The old surface area is multiplied by 3^2 = 9 to get the new surface area
.
If you asked "What would the surface area of the prism be if each dimension were quadrupled?"
, then you would multiply the old surface area by 4^2 = 16 to get the new surface area So really thats how you would solve that </span><span />
So,
To write fractions as decimals, we have to divide them.
If you want, you can subtract them.
0.93... - 0.416... = 0.51666...
