The percent equation is
n=2.8%×45 or n=0.028×45. where n is the unknown number.
the proportion would be
n/45=2.8/100
the answer is 1.26
The definition of a prime number is one in which there are no factors other than 1 and itself. For example, 5 has no other factors other than 1 and 5 (itself).
The number 1 is not considered prime nor composite.So, even though it is a square (1²), it is not a prime number.
All square numbers have a square root that is neither 1 nor itself: 16 is the square of 4, 49 the square of 7, and so on.
Due to the fact that square numbers have factors other than 1 and itself, square numbers are not prime.
Hope this helps! :)
The chart showing the quantities and prices is;
Best Deal 1
Quantity of Flour Price
3 pounds $5.25
5 pounds $9.75
7 pounds $12.60
10 pounds $14.20
12 pounds $18.24
Answer:
difference between last weeks best deal = $0.3
Step-by-step explanation:
Let's calculate the unit price for each of the quantities in the chart.
For quantity of 3 pounds;
We have; unit price = 5.25/3 = $1.75
For 5 pounds;. Unit price = 9.75/5 = $1.95
For 7 pounds; unit price = 12.6/7 = $1.8
For 10 pounds; unit price = 14.2/10 = $1.42
For 12 pounds; unit price = 18.24/14 = $1.3
Thus, last weeks best deal is the lowest = $1.3
Thus; difference between last weeks best deal is given as;
= this weeks best deal - last weeks best deal
This gives;
$1.6 - $1.3 = $0.3
25% of 584 is 146. If you meant to say "25% off of the dealer's cost", the answer would be $438, since you're finding what 25% of the original price is (146) and subtracting it from the original price. The equation would be 584 - 146 = 438. I hope this helped <3
