Answer:

4.3

Step-by-step explanation:

The area of a circle is pi(radius 2) So, the radius is just half of the diameter. The radius of the baseball is 1.5 and 1.5 x 1.5 x 3.14(pi) is 7.065. Then for the softball, 3.8/2 is 1.9, and 1.9 x 1.9 x 3.14(pi) is 11.3354 then 11.3354-7.065 is 4.2704 and that rounded, is 4.3

Hope this helped!❤

HELP HELP I don’t know how to do thissssss

Sophie [7]

Answer:

see below

Step-by-step explanation:

$p(x)=x^3-3x-1$ and $q(x)=x-1$

$p(x)+q(x)=(x^3-3x-1)+(x-1)=x^3 -2x-2$

$p(x)-q(x)=(x^3-3x-1)-(x-1)=x^3 -3x-1-x+1=x^3-4x$

$p(x) \times q(x)=(x^3-3x-1)(x-1)=x^4-x^3-3x^2+2x+1$

$\frac{p(x)}{q(x)} =\frac{x^2-3x-1}{x-1} =x^2+x-2-\frac{3}{x-1}$

A male punky fish has 9 stripes and a female punky fish has 8 stripes.I count 86 stripes on the fish in my tank.What is the rati

Andrews [41]

The ratio of male fishes to female fishes is 3 : 2

<u>Solution:</u>

Given, male punky fish = 9 stripes

Female punky fish = 8 stripes.

Total stripes = 86

<em><u>Finding the ratio of male fish to female fish:</u></em>

Let the number of male fishes be "m", and the number of female fishes be "n"

The, given that, total strips = 86

which means, total male strips + total female stripes = 86

$\text { 9 stripes per male } \times \text { number of male fishes }+8 \text { stripes for female } \times \text { number of female fishes }=86$

$\begin{array}{l}{\rightarrow 9 \times m+8 \times n=86} \\\\ {\rightarrow 9 m+8 n=86}\end{array}$

The only values that can satisfy above equation are m = 6 and n = 4

Now, ratio of male fishes to female fishes = m : n = 6 : 4 = 3 : 2

Hence, the ratio of male fishes to female fishes is found out as 3 : 2
