Let's use the variable "r" to represent the investment rate of the stocks:
2r(500) + r(800) = 45
1000r + 800r = 45
1800r = 45
r = 0.025
2r = 0.05
The $500 is invested at 5%

III Convert the following: -<br> a) 5 Km 20 m into m<br> b) 7 m 13 cm into m<br>​
nika2105 [10]

All you need to know is that a km is 1000 m ( as the prefix kilo always means 1000 let it be even 1kg and that is equal to 1000g )

also know

that a 100 cm is 1 m and that's cause the prefix centi is 10^–2 (0.01)

answering your question

a) 5km = 5000m

5km and 20m in m is 5000m + 20m = 5020m

b) 13 cm = 13/100m = 0.13m

7m and 12cm is 7m + 0.13m = 7.13m.

remember

1km = 1000m

100cm = 1m

Can two positive integers have their H.C.F and L.C.M as 12 and 512 respectively? justify.
DaniilM [7]

Here is your answer

NO

Reason:

H.C.F. divides the L.C.M. completely.

Here 512 is not completely divided by 12

So, two numbers can't have their H.C.F and L.C.M as 12 and 512 respectively.
