jada can write 3 1/4 pages in 8 minutes. At this rate, how many pages could jada write in 24 minutes?
makkiz [27]

Answer:

9  3/4  pages = x    

Step-by-step explanation:

\frac{pages}{minutes} = \frac{pages}{minutes}        change 3 1/4 to a decimal

\frac{3.25}{8} = \frac{x}{24}

3.25(24) = 8x

78 = 8x

\frac{78}{8} = x

9.75 = x  

9\frac{3}{4} =x

working with the fraction

3 1/4 /8 = x/ 24

3 1/4 (24) = 8x            

 13/4 (24) = 8x

  316/4 = 8x

  78 = 8x

78/8 = x

9 3/4 = x

Given a 10 foot length of tree trunk with a radius of 3 feet, what is the weight of the tree trunk section if it has a density o
Nutka1998 [239]

treat the tree trunk as a cylinder

v= pi x r^2 x h

using 3.14 for pi

3.14 x 3^2 x 10 = 282.6 cubic feet

282.6 * 45 =  12, 717 pounds

If g(x) = 3x + 2 and h(x) = 9x2 + 12x + 6, find a function f such that f ○ g = h
Virty [35]
F(g(x)) = f(3x+2) = h(x)=9x^2+12x + 6

Note that (3x+2)^2 = 9x^2 + 12x + 4, which is almost, but not quite, equal to h(x).

Let's experiment.  What if f(x) = x^2 + 2?

Then f(3x+2) = (3x+2)^2 + 2 = 9x^2 + 12x + 4 + 2 = 9x^2 + 12x + 6, which is the same as the given h(x).

Thus, f(x) is x^2 + 2.
