Pie graph because sometimes they don't have numbers, and when they do, they are not very precise, but they give a good visualization.
Whatever% of anything is just (whatever/100) * anything.
x = ounces of 14% iodine.
y = ounces of 29% iodine.
we know that in a 14% iodine solution, 14% is iodine and the rest is something else, we also know that "x" ounces of the solution have 14% of iodine, how much is that? (14/100) * x, or 0.14x.
likewise, in the 89 ounces of 47% solution there is (47/100) * 89 of iodine.
and likewise as well, in "y" ounces of 29% iodine there is (29/100) * y, or 0.29y of iodine.
bearing in mind that, whatever "x" and "y" may be, x + 89 = y, and that the sum of the iodine amounts also will equate 0.29y.
Do the same process for each of the 3
you have miles per how many minutes and you need miles per hour
you know 60 minutes make 1 hour convert the minutes to hours
this will gives you miles per equivalent hour
you need miles per 1 hour
Here is number 1
1) 5 miles in 20 minutes
5 miles in (20/60) hr = 5 miles in 1/3 hr
to get 1 hr multiply by 3
equation so keep the balance
5 * 3 = 15
rate = 15 miles per hour.
same process for the others
Answer:
Value of p is 3
Step-by-step explanation:
One of the root is 1.
So, putting 1 in the place of x in the given equation,
px²-4x+3p-8=0
or, p-4+3p-8=0
or, 4p-12=0
or, 4p=12
or, p=3
