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:
I think Jayden will get $16
Step-by-step explanation:
Given Information:
Volume of truck = 15 ft³
Area of base of container = 6 ft²
Required Information:
Height of truck = h = ?
Answer:
Height of truck = h = 2.5 ft
Step-by-step explanation:
The volume of the truck is given by
V = l*w*h
Where l is the length, w is the width, h is the height
The area of the base of container is given by
A = l*w
Where l is the length and w is the width.
Substitute the equation of area into the volume of the truck equation.
V = l*w*h
V = (A)*h
Re-arrange for the height,
h = V/A
h = 15 ft³/6 ft²
h = 2.5 ft
Therefore, the height of the clothing truck is 2.5 ft.
The answer is choice A) 2
The main cluster of data is the group {12, 12, 14, 17, 18, 19} as they aren't very far apart in distance (plot the values on a number line). The range of this group is 7 since 19-12 = 7. Compare this to the distance from 2 to 12 which is 10 units; a far greater distance than 7. So the value 2 is on its own on an "island" so to speak
