George is required to produce 500 frames for an art gallery. He spent $100 on the wood required for all these frames. He also spent $50 in polishing all the final frames. He rented two floors of an art gallery for about $700. What selling price should George charge the art gallery if he wants to break even?
Answer:
George should charge 1.70$ for each frame to break-even.
Step-by-step explanation:
Variable cost for the frames:
Wood + polishing = $100 + $50 = $150
Variable cost per frame would be:
$150/ 500 = $0.30
The fixed cost of the operation is $700.
George has to make 500 frames.
Fixed cost / (Selling price per unit – variable cost per unit) = 500
$700 / (Selling price per unit - $0.30) = 500
700 = 500 (Selling price per unit – 0.30)
700 = 500 * Selling price – 500 * 0.3
700 = 500 * Selling price – 150
(700 + 150) / 500 = Selling price
850 / 500 = 1.7

what must be multiplied to 3x + 7y to get 9x² - 49y²?
help.
Answer:
square the whole equation
Step-by-step explanation:
so, it will change from (3x + 7y)² to 9x² - 49y²
I hope this helps a little bit.
Answer:
(3x - 7y)
Step-by-step explanation:
we know that
.. (a + b) (a - b) = (a^2 - b^2)
=> (a + b) = (3x + 7y)
=>. (a^2 - b^2) = (9x^2 - 49y^2)
=> so, (a - b).= (3x - 7y)

Two square floor tiles are made of the same material.One costs 180 naira and its edge is 30cm long.Find the cost of the other if its edge is 50cm long
Answer:
300 naira
Step-by-step explanation:
Steps to answer this question
we have to first determine the cost per cm the answer gotten is then multiplied by 50cmcost per cm = 180 /30 = 6 naira
cost of the other edge = 6 naira x 50 = 300 naira

How do you find a slope and the Y intercept
Answer:
Step-by-step explanation:
Typically in a line the y intercept is the point where your graph crosses the y-axis, and the x value is 0 so (0,b) is the y-intercept where y-intercept is b
The slope can be found by finding the rate of change, so the change in y / the change in x
You can also calculate the slope with 2 points so (x1, y1) (x2, y2)
you take the y values and subtract them, then divide by the x values like this:
y2 - y1 / x2 - x1
If a line is going up to the right in Quadrant I then the slope is positive, if the slope of the line goes down in Quadrant IV then the line slope is negative
Slopes of horizontal lines are zero, the slope of a vertical line is undefined
We use the letter m to stand for the slope

Answer:
BC ≈ 14.7 m
Step-by-step explanation:
Using the Sine rule in Δ ABC
[tex]\frac{AB}{sinC}[/tex] = [tex]\frac{BC}{sinA}[/tex]
To find ∠ A subtract the 2 given angles from 180°
∠ A = 180° - (90 + 28)° = 180° - 118° = 62°
Then
[tex]\frac{7.8}{sin28}[/tex] = [tex]\frac{BC}{sin62}[/tex] ( cross- multiply )
BC × sin28° = 7.8 × sin62° ( divide both sides by sin28° )
BC = [tex]\frac{7.8sin62}{sin28}[/tex] ≈ 14.7 m ( to 3 significant figures )

The heights of the mountains in a mountain range are less than 20,000 feet. Write an inequality to represent the heights of the mountains, h, in this mountain range.
Answer:
D, far apart from each other.
Step-by-step explanation:
The inequality that represent the heights of the mountains in the given range is h < 20,000
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Given that, the heights of the mountains in a mountain range are less than 20,000 feet.
We need to write an inequality to represent the height of the mountain ranges,
Since, the height is less than 20,000,
Therefore, the inequality =
h < 20,000
Hence, the inequality that represent the heights of the mountains in the given range is h < 20,000

Baby Gina's birth weight was 8 pounds. One week after being born, she is 2.5% lighter. What is Gina's current weight?
Answer:
6 pounds
Step-by-step explanation:
Given data
Initial weight=8 pounds
We are told that a week later the weight reduced by 25%
Let us find 25% of 8
=25/100*8
=0.25*8
=2 pounds
Hence the current weight is
=8-2
=6 pounds

Pi High School ordered 40 science books. The next week, the school ordered 30 algebra books. The bill for the first order was $360 greater than the bill for the second order. The two bills together totaled $3960. Find the price of an algebra book.
Answer:
Each algebra book costs $60.
Step-by-step explanation:
A=bill for algebra books; S=bill for science books=A+$360
S+A=$3960 Substitute for S
A+$360+A=$3960 Subtract $360 from each side.
2A=$3600 Divide each side by 2.
A=$1800 The order for 30 algebra books cost $1800.
Individual book=A/30
individual book=$1800/30=$60 ANSWER: Each algebra book cost $60.
What happens to the hare(rabbit) population (size) when the lynx population increases to a high number? AND explain why this happens. What happens to the size of the lynx population when the hare(rabbit) population increases to a high number? AND explain why this happens. PLEASE HELP ME
At first, there are more lynx than rabbits. This is shown by the fact the orange curve is above the blue curve. Because there are more predators than prey, some predators will unfortunately go without food and starve (this assumes that rabbits are the lynx only food source). This die-off explains why the orange curve goes down or decreases.
As the predators die off, the prey has time to flourish. The rabbit population grows or increases. Note the blue curve going uphill as the orange curve goes downhill. The blue curve hits a peak point and it then goes down. This is due to the lynx population rebounding. There's more food for the lynx and the lynx population will increase. The lynx then eat the rabbits to bring the hare population down.
In short, as one population increases, the other decreases, and vice versa. This back and forth cycles indefinitely. This keeps things in balance so one population doesn't overwhelm a location. Keep in mind that I'm only focused on these two populations and no other animal species. Also, I'm not considering any other factors such as habitat loss. So this is a very simplistic view of what's going on in nature. It's considered a predator-prey model to give biologists a rough sense of what's going on.
The chart shows that we do have a cyclic up and down pattern for each population. For the most part, the peak rabbit populations seem to coincide with the lynx population increasing. Also, when the rabbit population is at its lowest, the lynx population is on the decline. Furthermore, when the lynx population is at its peak, the hare population is on the decline. The lynx population being at its lowest seems to coincide with the hare population increasing.
The exceptions to this general rule seem to be at around 1885, 1895, and 1905. During these time frames, it appears that the two populations are in lockstep together. In other words, they seem rise and fall at the same time. What could explain this is something like habitat loss that I mentioned earlier. Habitat loss would explain why a population decreases. Also, people hunting either animal would explain the population decrease if the hunting is intense enough. If the population gets too low, then governments may step in to enact endangered species laws to protect the animals so that the population could rebound again.

the slope of a line parallel to the line who is the equation 2x + y = 6
Answer:
-2
Step-by-step explanation:
Note that slope-intercept form looks like: y = mx + b
In this case, isolate the y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides:
2x (-2x) + y = 6 (-2x)
y = -2x + 6
Note in the slope-intercept form: y = mx + b
y = y
m = slope
x = x
b = y-intercept
In this case, your slope is -2. All lines parallel to the given equation will also have a slope of-2.

Answer:
5 per minute
Step-by-step explanation:
Answer:
The person ate 5 pies per minute
Step-by-step explanation:
If 12 pies were eaten in 60 minutes , you must divide the denominator (60) by 1 (the per minute). Whatever you do to the bottom, you must do to the top, so 60 / 12 is 5.
