which can only play a Blu-ray disc and the media-blue that plays Blu-ray disc and contains a
personal DVR. The players are assembled on two different assembly lines. Line 1 can assemble 2
units of the mini-blue model and 12 units of the media-blue model per hours, and Line 2 can
assemble 5 units of the mini-blue model and 5 units of the media-blue model per hours. The
company needs to produce at least 20 units of the mini-blue model and 70 units of the media-blue
model to fill an order.
Let x = the number of hours for Line 1
Let y = the number of hours for Line 2.
Write the system of inequalities that represents the minimum number of Blu-ray disc player that

Find the points on the ellipse
3x2 + y2 = 3
that are farthest away from the point (1, 0).
This question has to do with the Mathematical sub-topic in Geometry called Ellipse.
What is an Ellipse in Maths?An ellipse is a circle that has been stretched in one direction so that it is no longer symmetrical but oval in shape.
How does one find the points on the ellipse?Let us assume that the points on the ellipse is (cosθ, √3 sinθ)
Next let's minimize their distance squared from (-1, 0) taking a point on the ellipse as (cos θ- -1)² + (√3 sin θ)² =
cos²θ + 2cos θ + 1 + 3 sin² θ
(Substituting sin² θ + cos² θ = 1)
2 + 2 cos θ + 2 sin² θ
The derivative is given as
-2 sin θ + 4 sin θ cos θ =
-2 sin θ (2 cos θ - 1)
The above translates to 0 at sin θ = 0 or cos θ = 1/2, which results in 0°, 180°, 60°, 300°
Assuming we re-write the first derivative as - 2sin θ+ 2sin 2θ, the second derivative becomes:
-2 cos θ + 4 cos 2 θ
At 0°, 180°, 60°, 300°, we get 2, 6, -3, -3.
Therefore, our relative minima is given at 0°, 180°, while the relative maxima at 60°, 300°.
It is safe to declare, therefore that due to the nature of the function, the global minima and maxima will be among the four locations indicated above.
In addition to that,, 180° is the global minimum. This is because it is at the actual point, while 60° and 300° give the same value of the distance squared, thus both will each be maxima.
(cos θ, √3 sin θ) at 60°, 300° is (1/2, 3/2) and (1/2, -3/2)

a simple random sample of earthquake depths yields the following:

use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 5.00km
The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region.

Which expression represents y to the 4th power -36 in simplest factored form?
Answer:
(y^2 + 6)(y^2 - 6)
Step-by-step explanation:
First, substite variable x for y^2:
FOR x = y^2:
y^4 - 36
= (y^2)(y^2) - 36
= (x)(x) - 36
= x^2 - 36
Now, use the formula a^2 - b^2 = (a + b)(a - b):
x^2 - 36
= x^2 - 6^2
= (x + 6)(x - 6)
Finally, since the expression is factored for x, not y, substite y^2 in for x:
(x + 6)(x - 6)
= (y^2 + 6)(y^2 - 6)
[tex]= (y^2 + 6)(y^2 - 6)[/tex]

Required
Black- 35%
Blue-23%
How many more of black than blue were sold
First, calculate the difference in percentage sold
Multiply by the total phones sold;
Hence, 24 more blacks were sold than blue
Hope this helps
Brainliest appreciated :)
Answer:
The answer is 24
Step-by-step explanation:
The total amount of phone covers were 200.
35% of those were black. So, 200 x 35% (or 200 x .35) = 70.
70 of the phone covers sold were black.
23% of the covers were blue. So, 200 x 23% (or 200 x .23) = 46
46 of the phone covers sold were blue.
How many more black covers sold than blue covers means we subtract.
70 black covers - 46 blue covers = 24 more black covers sold.

Tom has 267 marbles, He shares the marbles out between himself and his two friends How many marbles does
each get? How many left over ?
Answer:
Each get 89 marbles and the leftovers are 0
Step-by-step explanation:
We have to ditribute the 267 marbles for 3 people so divide 267 by 3:
[tex]\frac{267}{3}[/tex] = 89
So each one gets 89
The leftovers are 0 because 267 is divisible by 3, means that if we divide 267 by 3 we will get a natural number ( no decimal part/ remainder=0)
remainder=0 → leftovers=0
charlie stands at point A while holding the control line attached to a model airplane. the plane travels 120 feet counterclockwise from point b to point c about how long is the control line
The counterclockwise direction of the airplane implies that it moves in the opposite direction
The control line could be 60 feet long
How to determine the length of the control line?The question is incomplete, as the figure that represents the control line and other parameters are not given.
However, a possible solution is as follows.
From the question, we understand that the airplane travels 120 feet counterclockwise.
The counterclockwise direction could represent that points B and C are on either sides of point A, such that:
AB = AC = 0.5* BC
So, we have
AB = 0.5* 120
AB = 60 feet
Hence, the control line could be 60 feet long

You are the head seamstress at a boutique that specializes in making prom dresses. You are supervising the construction of a new style of dress that will take 180 hours of work to complete. Twenty percent of this time is for beading. Thirty-five percent of this time is for adding ruffles. The remaining time is divided equally between embroidery and sewing. When pricing this style, hourly labor and material costs are $40 for beading, $35 for ruffles, $20 for embroidery, and $18 for sewing. The dress is then sold in the showroom for 25% more than the cost of labor and materials. How much will this dress sell for in the boutique?
The amount at which the dress will sell for in the boutique is $6716.25.
What is the sellig price of the dress?The total cost of beading = 180 x 25% x $40 = $1800
The total cost of ruffles = 35% x 180 x $35 = 2205
Time left for making embroidery and sewing = (100% - 35% - 25%)/2 = 20%
The total cost of embroidery = 20% x 180 x $20 = $720
The total cost of sewing = 20% x 180 x $18 = $648
Total cost = 5373
Selling price = 1.25 x 5373 = $6716.25

U-Move-It charges $42.00 per day for truck rentals, plus an additional mileage fee of $0.45 per mile for mileage over 20 miles. Which of the following systems of equations could be used to find the total mileage, m, that will make the cost, p, of renting a moving truck for one day equal at each rental company, assuming m≥20, is greater than or equal to, 20?
The equation used to find the total mileage, m, that will make the cost, p, of renting a moving truck for one day equal at each rental company is 45 miles
EquationTotal mileage = mCost = pMega movers:
Fixed cost per day = $19.50
Additional cost per mileage = $0.95
p = 19.50 + 0.95m
U-move:
Fixed cost per day = $42.00
Additional cost per mileage =$0.45
p = 42.00 + 0.45m
Equate the cost of both company19.50 + 0.95m = 42.00 + 0.45m
0.95m - 0.45m = 42.00 - 19.50

The volume of the solid is the amount of space in it.
The points on the graph are (0,0) and (1,7)
How to determine the points?The volume is given as:
V1 = 7
The scale factor is given as:
k
Let the new volume be V.
So, we have:
V = V1 * k^3
Substitute 7 for V1
V = 7k^3
Divide both sides by 7
k^3 = V/7
Take the cube root of both sides
k = (V/7)^1/3
Next, we test the options
a. (0,0)
k = (0/7)^1/3
k = 0 --- this is true
b. (1,1)
k = (1/7)^1/3
k = 0.05 --- this is false
c. (1,7)
k = (7/7)^1/3
k = 1 --- this is true
d (7, 1)
k = (1/7)^1/3
k = 0.05 --- this is false
e. (14,2)
k = (2/7)^1/3
k = 0.10 --- this is false
f. (49,2)
k = (2/7)^1/3
