Speed of current ------ y km/h
<span>distance with the current = 4(x+y) </span>
<span>distance against the current = 5(x-y) </span>
<span>we know that 3.5(x+y) = 70 </span>
<span>x+y = 20 </span>
<span>but 4(x+y) = 4(20) = 80 </span>
<span>then 5(x-y) = 80 </span>
<span>x-y = 16 </span>
<span>x+y=20 </span>
<span>x-y=16 </span>
<span>add them </span>
<span>2x = 36 </span>
<span>x = 18 , then y = 2 </span>
Answer:
F= 2
F=-2
F=x-25
Step-by-step explanation:
Answer: 16n + 7
Step-by-step explanation:
The limit of the expression can be achieved by differentiating the expression.
8n^2+5n+2/3+2n
Collect the likes term and rearrange
8n^2+7n+2/3
Differentiating with respect to n
(2×8)n^2-1 + 7n^(1-1)
16n + 7
2/3 automatically equal to zero since it has no variable n
Therefore, the limit of the expression is 16n + 7
Given:
The length of diagonals of a rhombus are 12 ft and 5 ft.
To find:
The area of the rhombus
Solution:
Area of a rhombus is:
Where, are two diagonals of the rhombus.
It is given that the length of diagonals of the rhombus are 12 ft and 5 ft.
Putting , we get
Therefore, the area of the rhombus is 30 square ft.
4/8 because if 2 already got pulled theres only 8 left four blue four yellow theres a 4 out od 8 chance youll pull them like that again
