1600(-400)= f is the y axis and -400 because its taking money from his account
<span>It
has no perfect square factors, unless you count 1 = 1^2. That's sort
of a degenerate case we don't usually count, since every integer has
that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!</span>
90 hazelnuts = 125g
Therefore, the mass of one hazelnut is this...
90 / 90 = 125 / 90
1 hazelnut = 25/18 grams
630 calories = 100 grams
100 divided by 25/18 = 72
Therefore...
630 / 72 = 1 hazelnut
AND THE ANSWER IS
8.75 calories = 1 hazelnut
So there are 18 coins in total right?(4 quarters+3dimes+5nickels+6 pennies)
So the number of pennies is 6
So probability of pennies (6) out of the whole coins(18) is 6/18 right?
This can be simplified to 2/6(since the highest common factor is 3 and dividing both by 3 gives you 2 and 6)
So probability of a pennie out of the piggy bank is 2/6
