A wheel has a circumference of 7 5/6 feet. How many times does it turn in 423 feet.
Answers
the length of one full turn is the same as it's circumference.
circumference x turns = total length
to find the number of turns, you have to divide total length by it's circumference.
423 / (7 5/6) = 423 / (47/6) = 54
75/6=12.5 and it will rotate 33.84 times to complete 423 ft

If you had invested only 1 month´s worth of the emergency fund in the savings account at a 3.15% APR and the remainder in the 45-day CD at a 4.65% APR. What is the difference in the interest earned in 45 days when compared with question three? Question three was- Your fixed expenses are $1,500.45 a month. Your emergency fund has four month´s worth of coverage. You invest half in a savings account with an interest rate of 3.15% APR and the other half in a 45-day CD with an interest rate of 4.65% APR. How much is your total interest in 45 days? I got $28.85 for this.
Answers
I answered this question before.
Given: Fixed monthly expenses: $1,500.45 Emergency fund is 4 month's worth: 1,500.45 x 4 = 6,001.80
Question 3: Half of the emergency fund is invested in savings account with interest rate 3.15% APR Half of the emergency fund is invested in 45-day CD with an interest rate of 4.65% APR.
Circumference of a circle with the given radius 36 inches
Answers
the answer is 226.19 in
Answer is 226.08 inches As circumference is 2πr Where π=3.14 radius r = 36 inches Circumference will be 2 π r 2 x 3.14 x 36 6.28 x 36 226.08 So the answer will be 226.08 inches
