Answer:
48
Step-by-step explanation:
Wrong : right
1 :12
Multiply by 4 because she gets 4 problems wrong
1*4 : 4*12
4 :48
If she gets 4 problems wrong, she gets 48 problems right
Answer:
102.5 ft
Step-by-step explanation:
The area of a rectangle is length x width.
You need to do 20.5 x 5 = 102.5
It helps to draw a picture so you can visualize it better.
For the rug, since the area = 144, what two numbers multiplied give you 144? You might already know that 144 is a perfect square, so 12 x 12 = 144. 12 is the length of each side of the rug.
√144 = 12
12 + 3 = 15. (Add 3 because the rug only covers a portion of the floor. The entire floor = the length of the rug + the part that isn't covered)
15 x 15 = 225 ft squared (Multiply both sides of the floor to get the area.)
225 ft squared - 144 ft squared = 81 ft squared <-- your answer
Each number in the code can be 1 of 10 numbers.
The total number of possible combinations is 10 * 10 * 10 * 10 = 10,000
The probability of getting 1234 would be 1/10,000
