Answer:
72.22 inches
Step-by-step explanation:
Okay so the formula for circumference is C=2πr so since the diameter is twice the radius, the radius is 11.5. Now you have to multiply 11.5 and 2. That equals 23. Now you have to multiply 23 by π which is about 3.14. 23 times 3.14 is 72.22 inches.
Hope this helped!! :D
Answer:
Identify the terms and coefficients of each expression. 1. ... Frank buys p pounds of oranges for $2.29 per pound and the same number of pounds of apples for $1.69 per pound. ... .690 = total cost ... Write an expression to represent each situation. 9. Eliza earns $400 per week plus $15 for each new customer she signs up.
Step-by-step explanation:
Answer:
1 gallon
Step-by-step explanation:
Since the relationship is direct, meaning as the number of square feet decreases, the number of gallons also decreases.
3:900 = x:300
solution:
3(300) = 900x
900=900x
x=1
Answer:
c) 68%
Step-by-step explanation:
The empirical rule states that most of the data will be within three standard deviations in a normal distribution. The 68% of the data will be within one standard deviation, the 95% will be within two standard deviations, and 99.7% of the data will be within three standard deviations.
A normal distribution is a continuous distribution in which values around the mean are the most frequents. It can also be called a bell-shaped distribution.
Answer:
Compound interest is the best.
Step-by-step explanation:
Simple interest is that which is not added to the initial capital once the term of the investment or credit has expired.
Compound interest is that which is added to the initial capital at the end of the investment or credit.
Simple interest:
I= C x i x t
15,000 * 0.05 * 5 = $ 750
Compound interest:
Cf= Ci (1+i)ᵗ
Cf = 15,000 * (1.039)^5 = $ 18,162.22
So, if Cf - Ci = I -> 3,162.22 is the compound interest.
