20 total oranges

5 are bad.

Subtract the bad from the total to find the number of good ones:

20-5 = 15

There are 15 good oranges out of 20 total.

Divide good by total then multiply by 100 to get the percentage:

15/20 = 0.75

0.75 x 100 = 75%

Answer: 75% are good

seropon [69]

Answer:

96 people.

Step-by-step explanation:

Exponential equation for a decreasing amount:

The exponential equation for a decreasing amount is given by:

A(t) = A(0)(1-r)^t

In which A(0) is the initial rate and r is the decay rate, as a decimal.

Currently, the number of people entering a shopping mall is 109.

This means that A(0) = 109

It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.

This means that r = 0.03

So

A(t) = A(0)(1-r)^t

A(t) = 109(1-0.03)^t

A(t) = 109(0.97)^t

Find the total number of people entering the shopping mall at the end of 4 hours.

This is A(4). So

A(4) = 109(0.97)^4 = 96.49

Rounding to the nearest whole number, 96 people.

Answer:

x > 60

Step-by-step explanation:

From the picture attached,

An arrow starting with a hollow circle from x = 60, directing towards positive numbers (greater than 60).

So, hollow circle will represent an inequality with no sign of 'equal to' and arrow will represent the sign of greater than (As moving ahead of 60).

Inequality representing the picture will be,

x > 60

What is the Slope and y intercept
Inessa [10]

Answer:

The slope is .075 and the y intercept is -.125

Step-by-step explanation:

8y = .2(3x -5)

Distribute the .2

8y = .6x - 1

Divide by 8

8y/8 = .6x/8 -1/8

y = .075x -.125

This is in slope intercept form  y= mx+b  where m is the slope and b is the y intercept.

The slope is .075 and the y intercept is -.125
