A) draw a cube
i) 16cm
ii) 80 cm
b)64 cm
Ok so draw the outline of a cube with 4cm each. There is six sides and the area is just multiplying 4 by 4. So, since the area of each side is 16, and there is 6 sides, the surface area is 80 cm. The volume is just length x width x height (4x4x4) so it’s 64 cm cubed.

Let C ( t ) be the number of US cell phone subscribers in millions in t years since 1995. A linear model for the data is F ( t )
Andru [333]

ANSWER

In 16 years time.


EXPLANATION.



If the number of subscribers is 324 million, then it means


f(t)=324


But we were given that,


f(t)=18.997t+16.711



This implies that,


324=18.997t+16.711


We now solve for t,



324-16.711=18.997t



307.289=18.997t



\frac{307.289}{18.997}=t



16.17566=t



That will be approximately in the 16th year.

➷The best metric unit to use for the mass of a grasshopper is grams, because a grasshopper is very light and a gram is small.

One gram is about the weight of a paper clip or a butterfly.
