Close rectangular box has three couples of identical parallel faces.
there are two faces 6''×5'',
two faces 6''×3''
and two faces 5''×3''
So, the area of the box would be the total of the areas of the faces:
A = 2· 6·5 + 2· 6·3 + 2· 5·3 = 2·30 + 2·18 + 2·15 = 60 + 36 + 30 = 126 [square inches]
Answer:
-2.1y + 12.9
Step-by-step explanation:
Answer:
equilateral triangle all angles add up to 180 and are equal so each angle is 60 degrees
angles on a line add up to 180.
angle CBD = 180-60 = 120
DBC is an isosceles triangle so it's base angles are the same.
180-120= 60
60/2=30

Step-by-step explanation:
Answer: A. The expression reveals the approximate rate of increase in the number of subscribers if measured six times a year.
Step-by-step explanation:
Here, The number of subscribers to an online magazine is increasing by 34% each year. The function represents the number of subscribers after t years.
where represents rate of increase in the number of subscriber.
If rate is measured six times a year
then the number of subscriber,
( approx)
Thus, when we measure increment in six times a year then the rate rate of increase in the number of subscribers=
Therefore Option A is correct.
Note: Option B) is incorrect because rate of increase in the number of subscribers if measured three times a year = ( approx)
Option C) is incorrect because rate of increase in the number of subscribers if measured four times a year = ( approx)
Option D) is incorrect because rate of increase in the number of subscribers if measured two times a year = ( approx)
