Hello!

The chance of getting a football card is 7 / 10
The chance of then getting a basketball card is 3 / 10

Multiply these two numbers

7/10 * 3 / 10 = 21/100

21/100 = 0.21

The answer is 0.21 or 21%

Hope this helps!

X will be used for the value of money she earned that week.

H represents the normal hours she worked.

D represents the number of days.

Y will represent the hours on the holiday.

Since she would be getting time and a half on the holiday, you would need to find how much time and a half pay would be first.

Time and a half = 5.50(1/2) + 5.50 = $8.25/hr for the day or holiday only.

X = 5.50(H)(D) + 8.25(Y)

Plug in your numbers

X = 5.50(7)(5) + 8.25(4)

X = 192.5 + 33

She made $225.5 that week.

Answer:

Step-by-step explanation:

When two chords intersect inside the circle, the product of their segments are equal.

BE * ED = AE * EC

x *3x = 4 *3

3x²   = 12 {Divide both sides by 3}

  x² = 12/3

  x² = 4

  x = √4

  x = 2
