1/6
This is because the probability of pulling a red is 1/3. Multiply that by itself to find the chance of repeating.
Least common denominator of those two fractions is 15
Because 15 cant go any less
3 × 1 = 3 15 × 1 = 15
3 × 2 = 6
3 × 3 = 9
3 × 4 = 12
3 × 5 = 15
Answer:
144%
Step-by-step explanation:
36 divided by 25 is 1.44 and to change it it percent u just move the decimal point.
So, you have to have your equation in terms of dimes. What you said about what he has: four more nickels than dimes in his pocket. Will help with our equation.
We know what a nickel and dime is worth. A nickel is .05 and a dime is .1
We don't know how many dimes are in his pocket, since we're trying to solve it.
.1x+(4+x).05=1.25;
In the parenthesis, it shows how there are four more nickels. Let's solve it now.
.1x + (4+x).05=1.25
.1x + .2+ .05x = 1.25; Let's add like terms.
.15x + .2 = 1.25; Subtract .2 from both sides.
.15x= 1.05
1.05÷.15= 7 =x
There are 7 dimes in his pocket, let's check our answer.
We now know there are 11 nickels, since there are four more nickels than dimes.
11(.05) +.1(7) = 1.25
.55+ .7 = 1.25
Now that we've tried it, we know there are 7 dimes in his pocket.

To find the top and bottom circles you use:
2(pi x r^2)
- your r (radius) is half of the diameter so 3.
To find the part around it you use:
2 x pi x r x height
Circles: 2(pi x 3^2) = 56.5487
Rectangular around: 2 x pi x 3 x 5 = 94.2478
- then add them together
56.5487 + 94.2478 = 150.7965 yards^2
