Hudson bought several cans of tennis balls. Each contained both green and yellow tennis balls. He purchased 10 green tennis ball

svp [43]

Answer:

1

Step-by-step explanation:

We don't know how many cans Hudson bought.

We are told, he bought:

10 green balls

5 yellow balls

Each can has 2 green balls, so there are:

10/2 = 5 cans

How can we distribute 5 yellow balls in 5 cans? Simple!

5/5 = 1

Put 1 yellow ball in each can.

So, each can will have:

2 green + 1 yellow (balls)

So, each can has 1 yellow ball

My name is Ann [436]

The solution to the expressions given are;

9 -9t/ 12 - 5t

a. 20/ 169

b. -170/ 169

c. 386/ 169

d. -10/ 169

<h3>How to solve the expressions</h3>

Given:

$\frac{9 - 19t}{12 - 5t}$

We can see that both variables in the numerator and denominator have no common factor, thus cannot be factorized further

a. $\frac{203}{169} - \frac{183}{169}$

First, let's find the lowest common multiple

LCM = 169

= $\frac{203 - 183}{169}$

= $\frac{20}{169}$

= 20/ 169

b. $\frac{13}{119} - \frac{183}{119}$

The lowest common multiple is 119

= $\frac{13 - 183}{119}$

substract the numerator

= - 170/ 119

c. $\frac{203}{169} - \frac{183}{169}$

The lowest common multiple is 169

= $\frac{203 + 183}{169}$

= 386/ 169

d. $\frac{9}{169}- \frac{19}{169}$

The lowest common multiple is 169

= $\frac{9 - 19}{169}$

= - 10/ 169

Thus, we have the solutions to be 9 -9t/ 12 - 5t, 20/ 169, -170/ 169, 386/ 169, -10/ 169 respectively.

h(x)= \dfrac{1}{8} x^3 - x^2h(x)= 8 1 x 3 −x 2 h, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided b

Nesterboy [21]

Answer:

$\dfrac{1}{2}$

Step-by-step explanation:

Given the function $h(x)=\dfrac{1}{8}x^3-x^2$

The average rate of change of the function h(x) over the interval $a\le x\le b$ can be calculated using formula

$\dfrac{h(b)-h(a)}{b-a}$

In your case,

$a=-2,\\ \\b=2,$

so the average rate of change is

$\dfrac{h(2)-h(-2)}{2-(-2)}\\ \\=\dfrac{(\frac{1}{8}\cdot 2^3-2^2)-(\frac{1}{8}\cdot (-2)^3-(-2)^2)}{4}\\ \\=\dfrac{(1-4)-(-1-4)}{4}\\ \\=\dfrac{-3+5}{4}\\ \\=\dfrac{2}{4}\\ \\=\dfrac{1}{2}$
