Answer:
d. 3/2r+2c ≤ 10
Step-by-step explanation:
The amount of flour Molly needs for r batches of oatmeal raisin cookies is ...
3/2r
The amount of flour Molly needs for c batches of chocolate chip cookies is ...
2c
The total amount of flour Molly can use for cookies cannot exceed the amount available, so ...
3/2r + 2c ≤ 10

<em>Comment on the question</em>
The wording is a bit odd. It asks for the amount of flour available—after it tells you the amount available is 10 cups. (I might write that as <em>f ≤ 10</em>.) The answer choices clearly suggest that what is wanted is a representation of the possible mix of batches of cookies for which Molly could use the available flour. IMO, this is another instance of poor editing of math problem wording.
Answer: You can use any one altitude-base pair to find the area of the triangle, via formula A = (1/2) bh. In each of those diagrams, the triangle ABC is the same. The green line is the altitude, the height, and the side with the red perpendicular square on it is the base. All three sides of the triangle get a turn.
Step-by-step explanation:
Answer:
x = 4.9t²
Step-by-step explanation:
x is directly proportional to t²
x = kt²
When t = 2 , x = 19.6
Substitute into the equation
x = kt²
19.6 = k * 2²
19.6 = k * 4
19.6 = 4k
k = 19.6/4
k = 4.9
Substitute the value of k into the equation:
x = kt²
x = 4.9t²
PEMDAS is order of operations...
Parentheses first, you can combine like terms...
8(6j+7)
Multiplication/division is next...8 times each term inside the parentheses
48j+56
Since there is one term with a variable and one is just a number that is as far as you can go...there are no more like terms...
