If George's driveway is a rectangle 12.2 m by 3.0 m, its dimensions in cm are
... 1220 cm long × 300 cm wide × 2 cm deep
Thus the volume of gravel required is
... (1220 × 300 × 2) cm³ = 732,000 cm³
George needs about 0.732 bags, so he will probably need to buy 1 bag.
Answer:
k
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. ... Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
Answer:
The slope would be 3.
Step-by-step explanation:
The formula for finding slope is 
We can plug these numbers into the equation by doing 
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
is 3, which is how you get your answer.
I hope this helps! :)

Answer:
Step-by-step explanation:
<u>Mean of the data = sum of the data / number of frequencies:</u>
- (40 + 38 + y + y + x + 32)/6 = 36
- 2y + x + 110 = 36*6
- 2y + x = 216 - 110
- 2y + x = 106
Correct choice is d
