Answer:
<em>A unit rate is something over a unit of something else.
</em>
<u>Such as:</u> (50 miles) / hour
If you have (150 miles) / 3 hours
This is not a unit rate, therefore you have to divide the top and bottom by 3 to get the unit rate
(150/3 miles) / (3/3 hours)
(50 miles) / hour
Hope this helps :)
For the first digit, you have two possible choices: 1 or 2. For *each* of those choices, you can choose 1 or 2 for the second digit in the number, and for each of *those*, you can choose 1 or 2 for the third digit of the number.
That’s 2 * 2 * 2 or 8 possible 3-digit numbers you can make with the digits 1 and 2.
Hi there!
We can use the following equation:
z = amount of standard deviations away a value is from the mean (z-score)
σ = standard deviation
x = value
μ = mean
Plug in the knowns for both and rearrange to solve for the mean:
Other given:
Set both equal to each other and solve:
Answer:
The number of flower pots that were sold is 50
Step-by-step explanation:
Let x represent the number of flower pots that the store owner bought and sold.
A store owner bought some flower pots for $1,200. Therefore, the cost price for each flower pot would be
1200/x
The flower pots were sold for $2,700, with a profit of $30 per pot. The means that the selling price of each flower pot would be
2700/x
Profit = selling price - cost price
Therefore
2700/x - 1200/x = 30
Multiplying both sides of the equation by x, it becomes
2700 - 1200 = 30x
30x = 1500
x = 1500/30 = 50
