There are 7 numbers.
Each number can be paired with the remaining 6 numbers.
7 x 6 = 42 different two digit numbers can be made.
Answer:
To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
R=25
a^2+b^2=c^2
7^2+24^2c^2
49+576=c^2
625=c^2
c=25
1. 3^3= 27in^3
2. 3*2*4= 24ft^3
3. 8*10*12= 960yd^3
4. 7*6*5= 210m^3
5. 5^3= 125cm^3
Hope I got it right for your sake.
