Answer:
9 weeks
Step-by-Step Instructions:
Step 1: State what is know
Bart deposits 10 dollars every week
Bart has 90 dollars in his account
Step 2: Find a way to solve for how many weeks Bart ha been depositing money
Total money in account / 10 dollars deposit per week = weeks he has been depositing
Step 3: Substitute in values and solve
90/ 10 = 9
Step 4: State your findings
Therefore Bart has been depositing money for 9 weeks
Answer:
The cylinder is cheaper to make because it has less surface area.
Step-by-step explanation:
In order to find the surface area of a cylinder, you do 2πrh+2πr²
We need the radius, which is half of the diameter, so then we have 2π(3·12)+2π·3² which gets us 282.72
We also need the surface area of the rectangular prism which we can get by 7x4 + 7x4 + 12x7 + 12x7 + 12x4 + 12x4 which gets us 320
282.72 < 320

Answer:
very less
Step-by-step explanation:
When rolling a fair 6 sided die 5 times there are 6^5 possible combinations.
Of those, there are 5 ways to roll exactly four sixes, and each of those ways have 5 possible results on the die which has not rolled a six, plus there is 1 way to roll five sixes. 5*5+1=26 combinations with at least four sixes.
Now, take the number of results which fit your conditions, divide by the number of possible results and you get your answer: 26/7776 which can be reduced to 13/3338, a bit less than 0.4%
