Gas prices are projected to increase 124% by April. A gallon of gas currently costs $3.17. What is the
projected cost of a gallon of gas in April?

Answers

Answer: $7.1

Step-by-step explanation:

Since the gallon of gas currently costs $3.17 and the prices are projected to increase 124% by April. Then, the projected cost of a gallon of gas in April will be:

= $3.17 × (100% + 124%)

= $3.17 × 224%

= $3.17 × 2.24

= $7.1

Therefore, the projected cost will be $7.1

Jasmine had an average daily balance of $1,608.24 for the last billing cycle, which had 31 days. If her credit cards charges an APR of 22.99%, what would her finance charges be for the last billing cycle?

Answers

Answer:

Finance per billing cycle = $ 30.91

Step-by-step explanation:

First, we will calculate the APR for 1 day:

APR per day = (22.99%/year)(1 year/12 month)(1 month/31 days)

APR per day = 0.062 % / day

Now, we will calculate the finance per day:

Finance per day = (Daily Balance)(APR per day) = ($ 1608.24)(0.062 %/day)

Finance per day = $0.99/day

Now, we will calculate the finance for one billing cycle:

Finance per billing cycle = (Finance per day)(31 days) = ($ 0.99/ day)(31 days)

Finance per billing cycle = $ 30.91

Pythagorean Theorem: a2 + b2 = c2

Answers

Answer:

b= the square root of 20

Step-by-step explanation:

if a^2+b^2=c^2, then c^2-a^2=b^2. 6^2-4^2=c^2. So 36-16=b^2. 36-16=20.20=b^2, then take the square root of both sides to get b= the square root of 20.

A man borrowed a Rs 5000 from a money lender for 5 years at the rate of 8% per annum. How much interest did he pay for 5 years? Also find the amount.​

Answers

Answer:

Interest = Rs 2000

Amount = Rs 7000

Step-by-step explanation:

Amount = Principal + Interest

Given

Principal = Rs 5000

Interest= PRT/100

Interest = 5000*8*5/100

Interest = 50*40

Interest = Rs 2000

Amount after 5years = 5000 + 2000

Amount after 5years = Rs 7000

Samantha saw two bottles of ketchup at the store for the same price. One bottle contained 4 pints of ketchup, and the other contained 1.25 quarts of ketchup.

Which bottle was the better bargain?

Answers

Answer:

The 4 pint ketchup bottle was the better bargain.

Step-by-step explanation:

To find which bottle was the better bargain, find which one had the most amount of ketchup in it.

In one quart, there are 2 pints.

Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:

1.25(2)

= 2.5

Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.

So, the 4 pint ketchup bottle was the better bargain.
