P(rolling a 5) = 1/6
P(rolling a 1) = 1/6
P(rolling a 1 or a 5) = (1/6 ) + (1/6) = 1/3
The answer is 1/3
The area is found by multiplying the length by the width.
The original area = 60 x 40 = 2,400 square feet
He wants to make it 1/2 that size, so the new size would be 2,400 / 2 = 1,200 square feet.
To find the length divide the new area by the new width:
1,200 / 30 = 40
The new length should be 40 feet.
Answer:
- an = 160·0.85^(n-1)
- $51.29
Step-by-step explanation:
In the given formula, a1 refers to the first term of the sequence (160), and r refers to the common ratio (136/160 = 0.85). Putting these values into the formula gives ...
a) Explicit formula: an = 160·0.85^(n-1)
__
b) The 8th term is found by putting n=8 into the formula and doing the arithmetic:
a8 = 160·0.85^(8-1) ≈ 51.29
After 8 months, the price is predicted to be $51.29.
Answer:
The salary of Sydney to meet the loss due to inflation should be 11.85 per hour
Step-by-step explanation:
The inflation rate is 3%
This means that the alary amount will reduce by 3%.
3% of Sydney's hourly salary is
= 0.345
Hence, the new salary must increase by 0.345 dollar per hour
The salary of Sydney to meet the loss due to inflation should be 11.50 + 0.345 = 11.845 or 11.85
