We can display the information given as an equation:
2000 *

= 4000; r = increase per annum
Now, we rearrange and solve for r:

= 2
r =
![\sqrt[19]{2}](https://tex.z-dn.net/?f=%20%5Csqrt%5B19%5D%7B2%7D%20)
= 1.037.....
We can now work out the increase for 5 years like so:
2000 *

= 2400.205..... ⇒
$2400
Answer:
L = 62.5cm; B = 30cm
Step-by-step explanation:
P = 2 (L+W): L=25cm; W=12cm
=2 (25+12)
=50+24
P = 74cm
For a congruent rectangle with P = 185cm
A: 74 = 2 (25 + 12)
B: 185 = 2( ? + ?)
Since A/B are congruent;
185/75 = 2.5
B = 2 (2.5* (25 + 12)
= 2 ( 62.5 + 30)
= 125 + 60
= 185
Hence, B: L = 62.5cm; B = 30cm
185cm = 2 (62.5 + 30)
Answer:
Charges what?
Step-by-step explanation:
Unfinished...
Step-by-step explanation:
First, subtract 3 from 13.67 so we can find out the minutes only and not the minutes along with the monthly bill.
This will come out to be 10.67
Now, we will divide 10.67 by .11
This will come out to be 97.
This means he was billed for 97 minutes on the phone
Hope I helped!
Please tell me if this is wrong and my most sincere apologies if it is.
Answer:
a) 8 subsets
b) 32 subsets
Step-by-step explanation:
The total number of subset of a set is known as the power of the set
Power of a set is expressed as;
P = 2^n
n is the number of element in the set
a) For a set containing 3 elements
n = 3
Power of the set = 2³
Power of the set is 8
This means that the set contains 8 different subsets
b) Cardinality of a set is the total number of element in the set
If the cardinal number of a set is 5, this means that the set contains 5elements
Hence the power of the set will be;
P = 2^5
P = 32
Hence the total number of subset for set whose cardinal number is 5 is 32
