Step-by-step explanation:
perimeter of square = 30cm
perimeter of rectangle = 30cm
area of square is = 30×30= 900 cm
hope it helps , make sure to follow !!!!
1 in 38.
Nothing much to say about this problem. There are 38 spaces on the roulette wheel and an every space on a fair wheel has an equal probability of being selected. So you would expect 1/38 = 0.026315789 = 2.6315789% of the time for the number 21 to show up.
Answer:
Step-by-step explanation:
Lets say Rhonda drove x miles, then Jamie drove 2x miles
x+2x=90
3x=90 divide each side by 3
x=30
so Rhonda drove 30 miles and Jamie drove 30*2=60 miles
Answer:
15 hours
Step-by-step explanation:
We can use the formula below to solve this:
Where
t is the time taken for BOTH to fill up the pool [6 hours]
a is the time taken by first tap [10 hours]
b is the time taken by second tap [we need to find this]
Now putting in all the into and solving for y, we get:
Hence, its gonna take 15 hours for the second tap to fill the pool alone.
Answer:
A) 3/110
B) 3/110
C) 3/110
D) The order doesn’t matter as long as you are drawing out the same three colors. The probability doesn’t change.
Step-by-step explanation:
A) 3/12x3/11x4/10=36/1320= 9/330 = 3/110
B) 3/12x4/11x3/10=36/1320= 9/330 = 3/110
C) 4/12x3/11x3/10=36/1320 = 9/330 = 3/110
D) The order doesn’t matter as long as you are drawing out the same three colors. The probability doesn’t change.
I hope this helps! Have a good day (PLZ GIVE BRAINLIEST)
