Answer:
0.7 x 10 ^ -9
Step-by-step explanation:
(3.5 x 10 ^ -4) ÷ (5 x 10 ^ 5)
3.5 / 5 x 10 ^ -4/ 10 ^ 5
=> 0.7 x 10 ^ -9
Given

I attached a graphical solution to the equation. The blue curve represent

while the red curve represent

From the equation, it can be seen that the curves representing the two terms in both sides of the equation does not meet.
Therefore, the statement about the graph that is true is "The curves do not intersect".
Answer:
Proportions and ratios are extremely important when administering medication. Many doses are determined by weight, and ratios are how those medications are often displayed.
since perimeter is the total of the length plus length plus width plus width:
L+L+W+W= 78 cm (given in the problem) as the total perimeter; and remember the length (we are told in the problem) is equal to 2 times width. so:
3 +2w+3+2w=78
6 +4w=78
6+4w-6=78-6
4w=72
w=18
Amount left = £50 - £24 = £26
Therefore £26 left.
