Answer:
A = 157 in^2
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2.
20/2 = 10
Now, we have our radius of 10 inches.
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values.
(1/2)(3.14(10^2)
Solve.
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157
Finally, we have our result which is 157 inches^2.
The total interest is =$875.76
The ending balance due = $19075.76
<h3>Calculation of interest using US rule</h3>
The US rule states that the year will be calculated in 360 days and not 365
- At day 70 the interest= 26,000 × 0.09 × 70/360
= 163,800/360
= $455
He owes $26,000+$455 = $26,455 but he pays $2,900 leaving him with a depth of $23,555 at day 70.
- At day 107: another 37 days has passed, therefore interest = $23,555 × 0.09× 37/360
= 78438.15/360
=$217.88
So at this time he owes $23772.88, but pays off $4900 leaving with a balance on day 107 of $18872.88
It will be another 43 days till the note is due, therefore the interest that would the generated the remaining days =
$18872.88×0.09×43/360
= 73038.0456/360
= $202.88
Therefore at day 150 he is owing $18872.88 + $202.88 = $19075.76 ( ending balance due)
The total interest generated;
= $455+$217.88+$202.88
= $875.76

Answer:
130.54°
Step-by-step explanation:
The formula for law of cosines is c^2= a^2+ b^2 -2ab cos(C),
a,b, and c are the sides of the triangle. C is the angle opposite to the side c.
To solve this problem add the given values into the formula, and solve for C.
10^2=5^2+ 6^2- 2(5)(6) cos(C)
100=25+36 - 2(5)(6) cos(C)
100=25+36 -60 cos(C)
100=61 -60 cos(C)
39= -60 cos(C)
cos^-1 (-39/60)= C
130.54°=C
Answer:
6.25 times 100 will equal to 625. When you multiply by 100, you can move the decimal two spaces to the right since there are two zeros, and you get 625.
