Answer:
There would be 350 girls in the school.
Step-by-step explanation:
We can find this by creating two proportions. the first fraction would be the number of girls out in the sample:
7/12
The second part would be the amount of girls in the whole school. We can set the girls as x since we do not know.
x/600
Now we can set the two equal to each other and cross multiply.
7/12 = x/600
600*7 = 12*x
4200 = 12x
350 = x
Answer:
No
Step-by-step explanation:
2 = 3 inches
2x5=10
10 = 3x5 of 15 inches
so no and it would take 8 minutes to fill up the tub
The given equation is 4x^2=x^3+2x.
On the left side it has 4x² and on the right side the expression is x³+2x.
So, if we have any system of equations in which we have these two expression which will be equal to any other variable then we can use that system of equations to find the roots.
Now notice that in option D it's given,
y=4x² and y=x³+2x.
So, if we will equate this equations then we will get the same above equation which will be use to find the roots.
So, D is the correct choice.
The doubled amount of sugar she would use is 1 1/2 cups
