20.50 is the amount patti is making per hour
Step-by-step explanation:
Tax charge
80 × 6.75/100 = 5.4
Cost + tax charge
80 + 5.4 = 85.4
Tip (15% of cost and tax)
85.4 × 15/100 = 12.81
(Cost + tax charge + tip)
85.40 + 12.81 = 98.21
therefore, $95 is not enough.
Answer:
10 quarters and 15 dimes
Step-by-step explanation:
25 = Quarters + Dimes
Total worth = $4.00 = 0.25* Quarter + 0.1*Dimes
so...
25 = Q + D , D = 25 - Q
4 = 0.25*Q + 0.1 * (25 - Q)
4 = 0.25 * Q + 2.5 - 0.1*Q
1.5 = 0.15Q
Q = 10
D = 15
The area of your game board is = 126 * 90 = 11340 cm^2;
A small suares has x^2 his area; where x measure his length;
Prime factorization
11340 | 2
5670 | 2
2835 | 5
567 | 3
189 | 3

21 | 3
7 | 7

11340 = 2^2 * 3^4 * 5 * 7 = 2^2 * ( 3^2 ) ^ 2 * 5 * 7 = 18^2 * 5 * 7
We observ that the possible length of the side is 18( we have 35 small squares ).
