Answer:
7 Days
Step-by-step explanation:
Miles cost:
$0.10 * 200 = $20
Daily Cost
Her budget at this point is $330 because $350 - $20 (the miles)
$330 / 42.72 = Roughly 7.72
Therefore Zoey can drive for 7 days before her budget runs out.
Answer:
975 bulbs
Step-by-step explanation:
1/40 bulbs were defective
That means 1-1/40 were not defective
40/40 - 1/40 = 39/40 were not defective
We have 1000 bulbs
Multiply the number of bulbs by the fraction that is not defective to get the number of bulbs that should not be defective.
1000 * 39/40 = 975 bulbs
Answer:
x = 6
Step-by-step explanation:
The product of x and 3 is 3x
5 increased by this product is 5 + 3x, thus
5 + 3x = 23 ( subtract 5 from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
Assume the bigger number is x, since the difference is 18, another one should be x - 18
So the product will be x(x-18) = x^2 - 18x = (x-9)^2 - 81
Since the minimum of (x-9)^2 is 0, then the minimum of the product is -81
