In this question, you need to convert the height of snow into the height of water. To answer this question, it would be easier to find the ratio of snow: water. If 1.5 feet of snow become 2 inch of water, then the ratio would be 2/1.5= 1 1/3.
Then for 3.5 feet of snow, it would be :
3.5 feet of snow * 1 1/3 inch of water/ feet of snow= 4 2/3 inch of water
Answer:
N = 1680
Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
Step-by-step explanation:
Given the word 'champion' which is an 8 distinct Letter word. The number of 4 letter groupings that could be formed from it can be given by the permutation since in this case order of letters are important.
The number of distinct 4 letter groupings can be given as;
N = nPr = 8!/(8-4)!, where n= 8 and r = 4
N = 8P4 = 8!/(8-4)!
N= 8!/4!
N = 1680
Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
Step-by-step explanation:
m and n are both located on the number line and are on the left of 0.
Therefore m and n are both negative reals.
m¹³ * n⁵
= (-)¹³ * (-)⁵
= (-) * (-)
= (+)
The answer is positive.
Answer:
$68.97
Step-by-step explanation:
Markup is the difference between the cost of an item and the price at which it is sold:
cost price + markup = selling price
Here, the markup is said to be 70%. The base for that percentage can be either the cost price or the selling price. The way this question is worded suggests the markup is 70% of the cost price.
So, we have ...
cost price + 0.70 × cost price = selling price
or
cost price × (1 + 0.70) = selling price
__
Then, to find the cost price, we can divide by its coefficient in this equation. Doing that gives ...
cost price = (selling price)/1.70
cost price = $117.25/1.70 = $68.97
The store's purchase price before the markup for this item was $68.97.
