Answer:
The correct answer would be D) 4.8x + 1.2 = 3.6; x = 0.5 mile
Step-by-step explanation:
This is because laps would be the dependent variable, so we know the number of them (4.8) would be multiplied by the variable (x). We also know that 1.2 is the constant. Now we can solve to make sure this is the right equation.
4.8x + 1.2 = 3.6
4.8x = 2.4
x = 0.5
-- 100% of the original number is ALL of it.
-- If it's increased by that amount, it becomes DOUBLE
(twice as much as) what it was originally.
Answer: 10 bags
Step-by-step explanation:
First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

You use 8 pounds of fertilizer per 1,000 square feet
So the amount of fertilizer you should use is:

As the fertilizer comes in bags of 50 pound then you need

Since you can not buy 9.2 bags then we round up to the next whole number.
Finally you need 10 bags of fertilizer
It is D. look how it skipped oz
40% from 25 is:
25 * 40% =
= 25 * 40/100 =
= 25 * 4/10 =
= 25 * 0,4 =
= 10
Another way is to find 1% of 25 and then multiply it by 40:
25 * 40% =
= (25 / 100) * 40 =
= 0,25 * 40 =
= 10
