Step-by-step explanation:
The probability of drawing a 10 from any suit is 4/52. Multiply this by the earnings, 500:

Hope this helps!
We have to use proportion to solve this problem.
75% -------------------180
100% ---------------------x
crossmultiply
75*x=100*180
75x=18000 /:75
x=240 - its the answer
We have similar problem here
8%---------------------60$
100% ------------------x
crossmultiply now
8*x=60*100
8x=600 /:8
x=75 - its the answer
Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
Answer:
Number of ways to chose bracelet = 2 ways

So,
Number of ways to chose bracelet = !2
Number of ways to chose bracelet = 2 × 1
Number of ways to chose bracelet = 2 ways
