Given that <span>Mrs.
Hawk assigns her students an average of no more than 15 questions on
each assignment. On their first 5 assignments Mrs. Hawk’s students had
11, 10, 13, 14, and 14 questions.
Let x be the number of questions she can have on the sixth assignment, then the inequality that
Mrs. Hawk can use to determine the number of questions she can have on
the sixth assignment is given by

You find this value by factoring. Factoring finds the zeros of the function. When the ball hits the ground, it has 0 height. Therefore, when the function goes through the x axis, it has a y value of 0. That means that when y = 0, the ball has hit the ground. Use the quadratic formula to factor
. Notice I rearranged the terms. When you factor that you get zeros of -3.19 and 2.19. The two things in math that will never EVER be negative are time and distance/length. Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.
10 crayons in all.
P (red) = 4/10 or 2/5
P (2nd red) = 3/9 =1/3 since there are only 9 crayons left from which to choose and only three of them are red (since we already pulled one).
2/5 x 1/3 = 2/15 = P (2 red) with no replacement.
I think its idfk…maybe?!?
Answer:
1750 trees
Step-by-step explanation:
Scale :
1 inch² = 1 mile²
Number of pine trees per square inch = 35
Area of model = 50 inch²
Hence,
Since scale factor is ; 1 inch² = 1 mile²
Area of forest will also be 50 mile²
Approximate number of trees on forest ;
Area * number of trees per square inch
50 * 35
= 1750 pine trees
