Answer:
For a flag with 2 different colours, there are 8 possible colours for the first colour to be chosen from and 7 possible colours (excluding the first colour already chosen) for the second colour to be chosen from, given that colours are different. Hence there are a total of 8 x 7 = 56 possible flags to be created.

Answer:
19 days
Step-by-step explanation:
Given
--- initial
-- rate
Required
Days when the fish gets to 30
The function is exponential and as such it follows;

Where x represents the number of days and y the number of fishes
Because the fishes decreases;

So, we have:

Express as decimal


In 



So, we have:

Divide both sides by 150

Take log of both sides

Apply law of logarithm

Make x the subject




<em>Hence, it takes approximately 19 days</em>
Answer:
g^3 - 7
Step-by-step explanation:
write
(2g^2+3g-8)-(5g+1)
(5g^3-8)-(5g+1)
and then you get g^3 - 7
sorry if it is not write but it should be
Answer:
x = 25
<B = 120 degrees
<C = 30 degrees
Step-by-step explanation:
Total angle measure of a triangle - 180 degrees
Add all the angles together to find the value of x
30 + 4x + 20 + x + 5 = 180
55 + 5x = 180
55 - 55 + 5x = 180 - 55
5x = 125

x = 25
<B = 4(25) + 20
<B = 100 + 20
<B = 120
<C = 25 + 5
<C = 30
