Answer:
17/49 or about 34.7%
Step-by-step explanation:
George has 85 cards out of 245 cards that are pitchers. Whever you hear "out of", it means to divide.
85/245 are pitchers.
you can simplify since 5 fits in both of those numbers
5*17=85
5*49=245
So, 17/49 or about 34.7%
First, turn the fraction into a decimal.
9.75
Second, multiply by 100%.
9.75 * 100% = 975%
Best of Luck!
Answer:
x = 14
Step-by-step explanation:
The polygon given has 6 sides
Sum of interior angles of a 6-sided polygon = 180(n - 2)
substitute n = 6 into 180(n - 2)
Sum of the polygon = 180(6 - 2) = 720°
Thus:
10x + 8x - 16 + 12x - 8 + 7x + 2 + 9x + 4 + 6x + 10 = 720
Add like terms
52x - 8 = 720
52x = 720 + 8
52x = 728
x = 728/52
x = 14
The answer will 3/2 and 4 :)
