Answer:
3x17x19 pls mark me brainliest thanks
Step-by-step explanation:
25- 20x + 4x^2
=4x^2 - 20x + 25
=4x^2 - x(10+10) +25
=4x^2 - 10x - 10x + 25
=2x(2x - 5) - 5( 2x - 5)
=(2x - 5)(2x - 5)
=(2x - 5)^2
So the chance of getting 1 blue marble is 30% or 3/10, the chance of getting another in a row is also 3/10 since its asking for both youd do 3/10*3/10 = 9/100
Answer:
Last option (bottom right)
Step-by-step explanation:
The scientific notation for 0.002 is 
(you move the decimal 3 to the right to get 2)
multiply the number of mustard seeds with this and you get 80. In scientific notation it is 
(move the decimal 1 to the left to get 8.0)
We know that:
The markup is the price added to the cost price of goods...
To find the markup, we must multiply the percent increase by the original price (before markup).
So:
10,000 x 5% (or 0.05) = ?
10,000 (You do not have to follow my way of multiplying, do what is comfortable for u)
x 5 (Ignore the decimals then we move it after we get the answer)
----------
50,000 move the decimal back 2 places so it is 500
The final answer is:
The markup amount is $500...
