A certain ball is dropped from 204 centimeters, and has a rebound factor of 72% (The height of the ball after each bounce is 72%

lina2011 [118]

Answer:

The equation that represents the relationship between the number of bounces and the height is $H = 204\cdot 0.72^{n}$ .

Step-by-step explanation:

According to this exercise, we notice that maximum height of the ball ( $H$ ), measured in centimeters, is reduced at geometric rate and as a function of the number of bounces ( $n$ ), with no unit, which is defined by geometric progression:

$H = H_{o}\cdot r^{n}$ (1)

Where:

$H_{o}$ - Initial height of the ball, measured in centimeters.

$r$ - Bounce factor, no unit.

If we know that $H_{o} = 204\,cm$ and $r = 0.72$ , then the equation that represents the relationship between the number of bounces and the height is:

$H = 204\cdot 0.72^{n}$ (2)

How do you solve this problem? Emma and Anna went to the market to buy 25 fruits. Emma got a few apples that cost $2 each, and A

sp2606 [1]

Anna bought 10 oranges

Explanation:

Let x denote the number of apples.

Let y denote the number of oranges.

The system of equations can be written as

$x+y=25$ and $2x+3y=60$

Let us solve the equation by substitution method.

Thus, from $x+y=25$ , the value of y can be determined such that $y=25-x$

Using the y value $y=25-x$ in the equation $2x+3y=60$ , we get,

$2x+3(25-x)=60$

Multiplying 3 within the bracket,

$2x+75-3x=60$

Adding the terms,

$75-x=60$

Subtracting both sides by 75, we have,

$x=15$

Thus, substituting $x=15$ in $y=25-x$ , we get,

$y=25-15\\y=10$

Thus, Anna get 10 Oranges.

x can really be anything because you did not include the sum for both expressions. so im not sure. its best to wait for someone else to answer. :/
