There are 52 cards, 4 jacks and 26 reds
Answer:
<u>C. 108.5 square feet</u>
Step-by-step explanation:
<u>Area of the deck</u>
- Area (left triangle) + Area (rectangle) + Area (right triangle)
- 1/2 x 6 x 7 + 10 x 7 + 1/2 x 7 x 5
- 21 + 70 + 17.5
- 91 + 17.5
- <u>108.5 square feet</u>
The initial amount in the jackpot was x dollars. The amount added to the jackpot was

. So the amount in the jackpot on the next day would be

dollars.
So the amount in the jackpot on the next day would

of the previous day. This can be modeled by a geometric sequence with the following formula

where A = amount in future,
x = initial amount,
r = rate of change,
n= number of days.
In this case, A = 4747.50, r =

Hence,
Thus x = $49.
B) 2
This is so because no number to the power of 2 has the result of 2
The other do
2x2 = 4
1x1 = 1
3x3 = 9
