<span>The answer is 97. The first expression is 1+4=5. In the next expression, both numbers are increased by 1 while their sum is increased by 7: (1+1)+(4+1) = (5+7). 2+5=12. In the next expression, both numbers are increased by 1 again, but the sum is increased by the next odd number (which is 9): (2+1)+(5+1)=(12+9). 3+6=21. So, the series will look like this: 1+4=5. 2+5=12. 3+6=21.4+7=33. 5+8=46. 6+9=61. 7+10=78- 8+11=97.</span>
25 - 3u = 2u
You need to get the variable, u, on one side of the equation. You can do this by adding 3u to both sides.
25 = 5u
Now you want to get u by itself, divide 5 off of both sides to find u.
5 = u
Answer:
we have a right triangle and to get the internal angle of the right triangle formed at the helicopter we subtract 62 degrees from 90 which equals 28 degrees
we now use the cosine to find the distance (d) from the helicopter
cosine 28 = 85/d
d = 85 / cosine 28 = 85 / 0.8829 = 96.2736 = 96 feet
Answer: 22.5 inches
Step-by-step explanation:
- the general formula for finding perimeter is
- a pentagon contains 5 sides
- note that this is a regular pentagon so it must contain 5 congruent sides
- each side will be 4.5 inches
- the formula can be changed to
and solved:
∴ 22.5 inches = perimeter of the pentagon
