Answer:
4/13
Step-by-step explanation:
The total number of marbles is 4 + 9 = 13.
The probability of choosing a yellow marble is the number of yellow marbles divided by the total number of marbles. Since there are 4 yellow marbles, the probability of choosing a yellow marble is 4/13.
I don't know but I guess there is an answer
Length = 3x
width = x
perimeter = 2* (3x+x)
equation:
2*(3x+x)=64
2*4x=64
8x=64
x=64/8 = 8 (thats width in meters)
43,000 in scientific notation is 4.3 x 10^4
