Answer:
The cost per pound of bananas is $0.84.
Step-by-step explanation:
The question asks to use the given information to set up a proportion and solve for the missing variable. In this case, we know that the cost of 2 1/4 (or 2.25) bananas is $1.89. Since they are asking for cost per pound, we can set up a ratio (fraction):
Since the cost of bananas is the same regardless of the number of pounds, we can set up a proportion to find the cost for just one (1) pound:
Where 'x' is the cost.
Using cross-multiplication and division we get: 2.25x = 1.89. Next, we use inverse operations to divide both sides by 2.25: 2.25x/2.25 = 1.89/2.25. Solve: x = 0.84 or $0.84 per pound.
Answer:
y = -5/3x -7
Step-by-step explanation:
If lines are parallel they have the same slope m = -5/3. Just need to figure out the new y-intercept going through the point (-9, 8).
y = mx + b
8 = -5/3(-9) + b
8 = 15 + b
b = -7
Now use m and b to form new equation of parallel line.
y = mx + b
y = -5/3x -7
Answer:
The room is 41 square meters.
Step-by-step explanation:
The square at the very top is 16 meters because 4 * 4 is 16.
The rectangle at the bottom is 6 meters because 2 *3 is 6
And that leaves you with the rest which is
11 -4 = 7
8 + 4 is 12
then you add them two together and you get 19 meters.
the last part is adding everything up which is 16 + 6 + 19= 41
the room is 41 square meters
If the parabola line crosses the x-axis twice, then it has two solutions, or the maximum/minimum of it is a point on the x-axis that means it has two solutions as a double root.
The measure of it's supplement is 117. You do 180 minus 63 and that makes 117.
