X + y = 1.....x = 1 - y
x * y = 0.09
y(1 - y) = 0.09
y - y^2 = 0.09....re-arrange
y^2 - y + 0.09 = 0
(y - 0.9)(y - 0.1) = 0
y - 0.9 = 0 x + y = 1
y = 0.9 x + 0.9 = 1
x = 0.1
y - 0.1 x + y = 1
y = 0.1 x + 0.1 = 1
x = 0.9
so ur 2 numbers are : 0.1 and 0.9
The formula to finding the volume would be v=l•w•h so then insert the values into that. You’re left with v=10•8•5. Multiply them together and you get 400cm cubed. That’s how much sand you’d need to fill the box.
Answer:u need help in general
Step-by-step explanation:
6^-3 / 6^5
Because the numerator has a negative exponent, use the negative exponent rule b^-n = 1/b^n
To do this move 6^-3 to the denominator:
1 / (6^5 * 6^3)
When you multiply identical numbers with exponents you add the exponents so (6^5 * 6^3) becomes 6^8
Now you have 1 / 6^8
Now raise 6 to the power of 8 to get:
1/1679616
Depending on the format your answer needs to be in you have 3 different answers:
1) 1/6^8 ( Leaving it as an exponent)
2) 1 / 1679616 (As a fraction)
3) 5.9537 x 10^-7 (As a decimal, round as needed)
