A=-2;b=9;c=9;
delta=b^2-4*a*c
root1=(-b+(delta^(0.5)))/(2*a)
<span>root2=(-b-(delta^(0.5)))/(2*a)
delta =153
root1 = -0.8423
root2 =<span> 5.3423
Correct Answer is D</span></span>
The answer is C
it's easier if you graph it
we know that the x of the unknown vertice is 4, because this is a rectangle and that vertices has to be on the same x line as the point below.
y of the unknown vertice has to be 1 because the vertice to the left needs to be on the same y line as the unknown vertice
The answer would be 3 to 1 as there are 3 dogs and 1 cat and the question asks for the ratio of dogs to cats.
Tommy ran 7 miles today for his track meet
For number 2, like i said in the comments, is 20 hours.
8/12*30
For number three, the answer is 38 Ibs on Mars.
4/10 = x/95
4*95/10= x
X= 380/10 which equals 38.
For 4, the answer is 48 oz of pineapple juice.
3 x 64/4 which equals to 48.
For 5, you will need 6 cups of flour.
