Answer:
48 i think
Step-by-step explanation:
Euler's formula tells us that
Suppose we subtract the two. This eliminates the cosine terms.
Divide both sides by
and you're done.
Answer:
Area of rectangular bedroom = 3000 square feet
Step-by-step explanation:
It is given that the total distance around the rectangular bedroom is 220 feet
perimeter of rectangle = total distance around the rectangle
hence the perimeter of rectangle = 220 feet
now width of rectangle = 50 feet
Let us assume the length of rectangular room be L
we have formula
now we plug perimeter = 220 and width = 50
so we have
(divide both side by 2)
(subtract 50 from both side )
Area of rectangular bedroom is given by
Area = length × width
Area = 60 × 50
Area = 3000 square feet
Answer:
1st volume = 160
2nd volume = 160 + 54 = 214
3rd volume = 160 + 54 + 32 = 246
4th volume = x + 54 + 32 = 246
Step-by-step explanation:
Given that:
Number of volumes = 4
1st volume = x pages
2nd volume = 54 more = x + 54
3rd volume = 32 more = x + 54 + 32
4th volume = 32 more = x + 54 + 32
Total number of pages = 866
Hence,
1st + 2nd + 3rd + 4th = 866
x + x + 54 + x + 54 + 32 + x + 54 + 32 = 866
4x + 226 = 866
4x = 640
x = 160
1st volume = 160
2nd volume = 160 + 54 = 214
3rd volume = 160 + 54 + 32 = 246
4th volume = x + 54 + 32 = 246
