It decreased 125, and 125 of 975 is roughly 13%, so the percent of decrease rounded to the nearest whole percent would be 13%.
In order to see how many real roots it has you have to see what the Δ is
So if Δ>0 then there are 2 real roots
If Δ=0 there is 1 real root
If Δ<0 no real root
And we know that:
Δ=b^2-4ac
So in the equation: Δ=b^2+4 and b^2 is always a number greater than or equal to 0 so when you add 4 to it, it is always greater than 0
So it has 2 real roots
If the full questions as below;
A dessert has both fruit and yogurt inside. altogether,the mass of the dessert is 185g. the ratio of the mass of fruit to the mass of yogurt is 2:3. what is the mass of yogurt?
total dessert 3:3
since the ratio of the mass of fruit is 2:3
the remaining would be
the ratio of the mass of yogurt which is 1:3
then the answer is:
the mass of yogurt would be one 3rd of the total dessert
185g÷3= 61.66g
cool? :)
