24 divided by 6( the amount of sides) is 4. The square root of 4 is 2 so each side is 2 cm. 2 cm tripled is 6 cm. 6 times 6 is 36 ( that is the surface area of one face). 36 times 6 (the number of faces) is 216 so the answer is 216 cm squared.

10. A salesperson advertises an increase of 100% in the radius of a new water pipe into a building.
a) The new pipe radius is how many times the size of the old radius?
b) By what factor will the flow rate of water through the pipe increase?
c) If the old pipe carried water at a rate of 10 gallons/second, at what flow rate will the
new pipe carry water?
d) What is the percentage increase in the flow rate of water in the new pipe?
Since the motorcycle moves horizontally, the vertical component of its velocity is zero. Determine the time it takes for the motorcycle to move down the 50-m cliff.
d = (v1)(t) + (0.5)gt²
Substituting the known values,
50 m = 0 + (0.5)(9.8)(t²) ; t = 2.26 s
Now for the horizontal component, the velocity is constant
90 m = (v)(2.26 s)
The value of v is approximately 39.82 m/s.
I’m pretty sure it’s basically just asking you the least amount she can buy (which would be 1) and the most she can buy (which is 55 packages)
Answer:
And the margin of error with this one:
Step-by-step explanation:
Assuming that the parameter of interest is the sample mean . And we can estimate this parameter with a confidence interval given by this formula:
(1)
For this case the confidence interval is given by (1.9, 3.3)
Since the confidence interval is symmetrical we can estimate the sample mean with this formula:
And the margin of error with this one:
