2/5 = x/15 // - x/15

2/5-(x/15) = 0

2/5-1/15*x = 0 // - 2/5

-1/15*x = -2/5 // : -1/15

x = -2/5/(-1/15)

x = 6

The price of a video game was reduced from $60 to $45. By what percentage was the price of the video game reduced?* O 15% O 25% O 75% 40% M​

Answers

Answer:

25

Step-by-step explanation:

The new price, $45, can be expressed as a percentage of $60 by taking it as a fraction of $60, converting to a decimal value, and multiplying by 100%. $45/$60=3/4=0.75, 0.75x100%=75%. So since 100%-75%=25%, the value was reduced by 25%.

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% of the height of the bounce before.). Which equation represents the relationship between the the number of bounces, n, and height, h, in centimeters? Group of answer choices

Answers

Answer:

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

Step-by-step explanation:

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

[tex]H = H_{o}\cdot r^{n}[/tex] (1)

Where:

[tex]H_{o}[/tex] - Initial height of the ball, measured in centimeters.

[tex]r[/tex] - Bounce factor, no unit.

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

[tex]H = 204\cdot 0.72^{n}[/tex] (2)

Answers

Answer:

y = -x + 9

Step-by-step explanation:

✔️Find the slope using (9, 0) and (7, 2):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1 [/tex]

Slope (m) = -1

✔️Find the y-intercept (b):

The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9

✔️Substitute m = -1 and b = 9 into y = mx + b

Thus,

y = -1(x) + 9

y = -x + 9

Answers

Answer:

The value of x is: 28

The value of y is: 32

Step-by-step explanation:

Let us solve the question

[tex]\frac{3}{4}[/tex] (x - 12) = 12 ⇒ (1)

→ Multiply each term in the bracket by [tex]\frac{3}{4}[/tex]

∴  [tex]\frac{3}{4}[/tex] (x) -  [tex]\frac{3}{4}[/tex] (12) = 12

∴  [tex]\frac{3}{4}[/tex] x - 9 = 12

→ Add 9 to each side

∵  [tex]\frac{3}{4}[/tex] x - 9 + 9 = 12 + 9

∴  [tex]\frac{3}{4}[/tex] x = 21

→ Divide both sides by  [tex]\frac{3}{4}[/tex]  to find x

x = 28

[tex]\frac{3}{4}[/tex] y - 12 = 12 ⇒ (2)

→ Add 12 to both sides

∴  [tex]\frac{3}{4}[/tex] y - 12 + 12 = 12 + 12

∴  [tex]\frac{3}{4}[/tex] y = 24

→ Divide both sides by  [tex]\frac{3}{4}[/tex] to find y

y = 32
