Answer:
0.205177 mi
Step-by-step explanation:
Step 1: Find conversions
12 in = 1 ft
5280 ft = 1 mi
Step 2: Use Dimensional Analysis
0.205177 mi
Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
Answer:
117 degrees
Step-by-step explanation:
So we already know that one angle is 38 degrees, so we have that one. The angle, 101 is exterior, and we have to subtract 180 from that to get the interior angle. We get a difference of 79. Since the sum of a triangle's interior angles are 180, we have to add 38+79 to get 117. Then, we have to subtract it from 180 to get the value of the interior angle as 63 degrees. Because x is on the outside, we have to again subtract 63 from 180 to get the missing value of x as 117.
The annual discount is 3%, therefore the total discount for 1 year would be:
4300 × 3 ÷ 100 = 129$
Now, you can set a proportion:
discount : annual discount = loan days : days in one year
21 : 129 = x : 360
x = 21 × 360 / 129 = 58.6 days
Hence, the loan duration was 60 days.
Answer:
20
Step-by-step explanation:
d = √(xb - xa)2 + (yb - ya)2 =
= √(18 - 2)2 + (15 - 3)2 =
= √162 + 122 = √256 + 144 =
= √400
= 20
