Answer:

The number of comic books did they have in all = 56

Step-by-step explanation:

The ratio of comics with Susan : Abe = 3 : 5

Let us assume the common factor on this ratio = m

So, the number of comics Susan has = 3 m

The number of comics Abe has = 5 m

Also, given: Abe had 14 more comic books than Susan

So, the number of comics Abe had = 14 + 3 m

⇒ 5 m = 3 m + 14

or, 2 m = 14, or m = 7

So, the number of books Susan has = 3 m = 3 x 7 = 21 books

The number of books Abe has = 5 m = 5 x 7 = 35

So, the book they have in all = 21 + 35 = 56

How do you figure these out?

I am Lyosha [343]

You do them in the order of operations, for example, on the 1st one you did 3x5 first and got 15, and then you added 2 and got a total of 17. On the second one, you did2x4 which is 8 and the you added 3 and made it a total of 11. So basically you do the last 2 boxes first, the add/subtract the first from the total of the other 2.

find the surface areas of the larger cone and the smaller cone in terms of pi. compare the surface areas using a percent. (the m

serious [3.7K]

ANSWER :

Surface area of larger cone : 24π units^2

Surface area of smaller cone : 6π units^2

The surface area of the smaller cone is 25% of that of the larger cone.

EXPLANATION :

From the given problem,

AB = 3 is the radius of the larger cone and the slanted height is BC = 5

DE = 1.5 is the radius of the smaller cone and the slanted height is EC = 2.5

Recall the surface area of the cone :

$A=\pi r^2+\pi rL$

where r = radius and L = slanted height.

For the larger cone, r = 3 and L = 5

$\begin{gathered} A=\pi(3)^2+\pi(3)(5) \\ A=24\pi \end{gathered}$

For the smaller cone, r = 1.5 and L = 2.5

$\begin{gathered} A=\pi(1.5)^2+\pi(1.5)(2.5) \\ A=6\pi \end{gathered}$

Comparing the surface areas :

The area of the smaller cone compared to the larger cone is :

$\begin{gathered} \frac{smaller}{larger}\times100=\frac{6\pi}{24\pi}\times100 \\ \\ =25\% \end{gathered}$

Find (f*g)(x) when f(x)=x^2-7x+12 and g(x)=3/x^2-16

IgorC [24]

The answer is: $(f*g)(x)= \frac{3x-9}{x+4}$

Explanation

Given functions are.......

$f(x)=x^2-7x+12$

$g(x)= \frac{3}{x^2-16}$

For finding $(f*g)(x)$ , we just need to multiply the two functions $f(x)$ and $g(x)$ . So......

$(f*g)(x)= f(x)*g(x)\\ \\ (f*g)(x)= (x^2-7x+12)(\frac{3}{x^2-16})\\ \\ (f*g)(x)= [(x-3)(x-4)][\frac{3}{(x+4)(x-4)}]\\ \\ (f*g)(x)= \frac{3(x-3)}{x+4} = \frac{3x-9}{x+4}$
