Answer:
4 questions
Step-by-step explanation:
To find a percentage of a number, you move the decimal mark all the way to the left.
87.5% becomes 0.875
Next you multiply 32 by 0.875 to find the percentage of questions that are completed
32 x 0.875 = 28
28 out of 32 questions have been solved, so now you subtract 28 from 32
32 - 28= 4
There are 4 questions to complete
Answer:
at a price of $2, the supply of gasoline will be around 11
Step-by-step explanation:
Answer:
Principal: $6,166.67
Principal: $5,200.00
Explanation:
<u><em>1. $6000 for 50 days at 20% p.a</em></u>
<u><em></em></u>
In 20% pa, pa means "per annum", i.e. "per year".
Assume simple interest:
Interest:
- Interest = Principal × number of days × annual rate / 360
- Interest = $6,000 × 50 × 20% / 360 = $166.67
Principal = principal + interest = $6,000 + $166.67 = $6,166.67
<u><em></em></u>
<u><em>2. $5000 for 5 months at 0.8% per month</em></u>
Assume, again, simple interest.
- interest: 0.80% per month
Interest:
- Interest = Principal × number of months × montly rate
- Interest = $5,000 × 5 × 0.80% = $200.00
Principal = principal + interest = $5,000 + $200.00 = $5,200
You can see that the accrued interests depend on the principal, the interest rate, and the time.
Answer:
Perimeter of rectangle ABCD = 47.62
Step-by-step explanation:
The perimeter of a rectangle is P = 2(length + width)
You need to find length and width
If you graph, you can pick your length length and your width
Pick two points after you graph, for 
Use the distance formula to find the length =
point B (4,5) will be point 1 and point C (8,-3) will be point 2
Substitute
length =
length = 
length = 8.94
Use the distance formula to find the width =
point C (8,-3) will be point 1 and point D (-2,8) will be point 2
Substitute
width =
width =
width =
width = 
width = 14.87
Now use formula P = 2(length + width)
P = 2(8.94 + 14.87)
Perimeter of rectangle ABCD = 47.62
The answer is A I believe.
