Answer:
16 questions answered correctly
Step-by-step explanation:
Since the student answered 80% of the questions correctly, we can find 80% of 20 to answer this question.
[] First we will convert the percent into a decimal format;
80% / 100 = 0.8
[] Then we will multiply this by 20 to find our answer;
20 * 0.8 = 16 questions answered correctly
Answer: 2.5%
Step-by-step explanation:
From the question, we are informed that John borrowed $20,000 from Beth and that he pays $500 per month in interest.
The percentage interest rate would be calculated thus:
= Amount paid as interest / Amount borrowed × 100
= 500/20000 × 100
= 2.5%
Answer:
201.06 square feet.
Step-by-step explanation:
=> The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
=> The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
=> Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet

Answer:
Thus; Jupiter travels at 480 miles/m and in 6 minutes, it will travel 2880 miles.
Step-by-step explanation:
First to convert it you need to multiply 8 miles per second by 60 seconds because there are 60 seconds in a minute:
8 miles x 60 s
1 second 1 min
The unit of seconds will cancel out so you will get 480 miles/ min
To get how far it travels in 6 min you need to multiply the speed by 6 minutes
480 miles x 6 min = 2880
1 min
The unit of minutes will cancel out to get 2880 miles
