The store owner estimates that no more than 2000 toys will be old every month.
x+y≤2000
One unit of toys A yields a profit of $2 while a unit of toys B yields a profit of $3, hence the total profit P is given by
P=2x+3y
The store owner pays $8 and $14 for each one unit of toy A and B respectively and he does not plant to invest more than $20,000 in inventory of these toys
8x+14y≤20,00

The solution set of the system of inequalities given above and the vertices of the region obtained are shown below:
Vertices of the solution set
A at (0,0)
B at (0.1429)
C at (1333,667)
D at (2000,0)
Calculate the total profit P at each vertex
P(A)=2(0)+3(0)=0
P(B)=2(0)+3(1429)=4287
P(C)=2(1333)+3(667)=4667
P(D)=2(2000)+3(0)=4000
The maximum profit is at vertex C with x=1333 and y=667
Hence the store owner has to have 1333 toys of type A and 667 toys of type B in order to maximize his profit

find the measures of these angles.
Answers
Answer:
angle 3: 57; angle 4: 33
Step-by-step explanation:
because they are complementary angles they add up to 90 so we set the equation up like this
x + 24 + x = 90
after combining like terms and subtracting 24 from each side you get this
2x = 66
when you simply you get this
x = 33
angle 3 is 57 when we add and angle 4 is 33

Given h(x) = -X – 1, solve for 2 when h(x) = -3.
Answers
Answer and Step-by-step explanation:
We are given the function h(x), which is equal to -x - 1.
We are told to solve for x and are given information the h(x) is equal to -3.
First, plug -3 in for h(x).
-3 = -x - 1
Second, add 3 to both sides, then add x to both sides.
-3 +(3 + x) = (-x - 1) +(3 + x)
(The 3's cancel out on the left, leaving the x, the x's cancel out on the right, leaving the -1 + 3, and -1 + 3 equals 2).
x = 2
When h(x) is equal to -3, x is equal to 2.

Two trains, traveling at speeds of 70 mph and 60 mph, leave the two cities at the same time and travel in the same direction so that the faster train will catch up to the other one. How long after the trains leave will the distance between them be 10 miles? How long after the trans leave will they be 10 miles apart for the first time? Help :(
Answers
=======================================================
Explanation:
Draw a horizontal number line. Plot point A at 0 and point B at 45 on the number line. The distance from A to B is 45 units to represent that 45 mile gap between the cities.
Let's say the trains travel to the right (aka to the east) along this number line train track. We'll place the faster train at location A, and the slower train at location B. This allows the slower train a head start. Eventually the faster train will catch up. If this was swapped and the trains still aimed to the right, then the trains will never be 10 miles apart.
-----------------------
Now we'll define two variables
x = number of hours that have elapsedy = the train's location on the number lineFor the faster train at location A, which I'll just refer to "train A" from now on, we can form the equation y = 70x. I'm using the idea that distance = rate*time to help form this equation.
For example, if x = 2 hours have passed by, then train A is at location y = 70*2 = 140 miles on the number line train track.
Train B will have the equation y = 60x+45. The 60x is formed in a similar manner compared to the 70x. The plus 45 at the end is due to the 45 mile head start. In other words, train B travels 60x miles on top of the 45 miles already done so far.
-----------------------
The two key takeaways from that last section is that we have these equations
y = 70xy = 60x+45which correspond to the locations of train A and train B in that order.
Now to the question at hand: how can we determine when the trains are 10 miles apart? The short answer is through subtraction. Moreover, we'll need to involve absolute value to ensure that distance is never negative.
So the distance expression between the trains at any given time x is:
distance between trains = |trainA - trainB|
distance = |70x - (60x+45)|
distance = |70x-60x-45|
distance = |10x-45|
Next, we set that distance expression equal to 10 and solve for x.
distance = 10 miles
|10x-45| = 10
10x-45 = 10 or 10x-45 = -10
10x = 10+45 or 10x = -10+45
10x = 55 or 10x = 35
x = 55/10 or x = 35/10
x = 5.5 or x = 3.5
-----------------------
Those two results mean that at the hour marks of 3.5 hours and 5.5 hours is when the two trains are 10 miles apart exactly.
The two trains start off being 45 miles apart. They both take off and train A will catch up to train B. Their gap will be 10 miles at the 3.5 hour mark. That gap shrinks to 0 at some point, and then grows again afterward. By the 5.5 hour mark is when the trains are again 10 miles apart. This time is when train A is in the lead and will remain so assuming the speeds stay the same.
It seems like your teacher is only concerned with when the trains are 10 miles apart for the first time and not the second. So your teacher is likely only expecting one answer and that would be 3.5 hours
Side notes:
3.5 hours = 3 hours, 30 minutes = 210 minutes.5.5 hours = 5 hours, 30 minutes = 330 minutes.Multiply by 60 to convert from hours only to minutes only.phineas has 3 times as many baseball cards as ferb.together,they have a total of 228 baseball cards.how many baseball cards does ferb have?

Step-by-step explanation:
As per the provided information in the given question, we have :
∠AOC = 60°∠BOC = 3xAB is a straight line.We've been asked to calculate the measure of ∠BOC.
Here, ∠AOC and ∠BOC are making linear pair of angles.
[tex]\odot [/tex] Linear pair : Linear pair of angles are nothing but the two adjacent angles of which non-common arms are two opposite rays. Now, as these both angles are making linear pair so,
[tex] \longrightarrow \sf{\quad { \angle AOC + \angle BOC = 180^\circ }} \\ [/tex]
Substitute the measure of ∠AOC and the expression of ∠BOC.
[tex] \longrightarrow \sf{\quad { 60^\circ+ 3x = 180^\circ }} \\ [/tex]
Transposing the like terms.
[tex] \longrightarrow \sf{\quad {3x= 180^\circ -60^\circ }} \\ [/tex]
Performing subtraction of the terms in RHS.
[tex] \longrightarrow \sf{\quad {3x= 120^\circ }} \\ [/tex]
Now, transpose 3 from LHS to RHS, its arithmetic operator will get changed.
[tex] \longrightarrow \sf{\quad {x= \cancel{\dfrac{120^\circ}{3}} }} \\ [/tex]
Dividing 120° by 3.
[tex] \longrightarrow \quad\underline {\boxed{ \textbf{\textsf{ x= 40}}^\circ }} \\ [/tex]
∴ The value of x is 40°.

A number, truncated to 1 decimal place, is equal to 15.4
Write down the lower and upper bounds of the number.
Answers
Answer:
Step-by-step explanation:
truncated means when its rounded up from the lower bound and upper bounds meaning lower bound=15.4 and upper bound=15.5
The lower and upper bounds of the number are 15.4 and 15.5 respectively.
Given data:
When a number is truncated to 1 decimal place, it means that only the first decimal digit is considered, and the rest of the decimal places are discarded. In this case, the number truncated to 1 decimal place is 15.4.
The lower bound of the number is the largest number that rounds down to 15.4 when truncated to 1 decimal place. Since 15.4 is already rounded down, the lower bound is simply 15.4.
The upper bound of the number is the smallest number that rounds up to 15.4 when truncated to 1 decimal place. The next number that rounds up to 15.4 is 15.5.
Hence, the lower bound is 15.4 and the upper bound is 15.5.

Item a:
The variables are:
x, which is the cost of on-site service.y, which is the cost of at-store service.z, which is the cost of by-mail service.Item b:
On-site service costs 3 times as much as at-store service, thus:
[tex]x = 3y[/tex]
By mail service costs $10 less than at-store service, thus:
[tex]z = y - 10[/tex]
Last week, the shop completed 15 services on-site, 40 services at-store, and 5 services by mail for total sales of $3100, thus:
[tex]15x + 40y + 5z = 3100[/tex]
The system is:
[tex]x = 3y[/tex]
[tex]z = y - 10[/tex]
[tex]15x + 40y + 5z = 3100[/tex]
Item c:
The cost of one on-site repair service is x.First, replacing the first two equations into the third, we find y, and then with it we find x.[tex]15x + 40y + 5z = 3100[/tex]
[tex]15(4y) + 40y + 5(y - 10) = 3100[/tex]
[tex]60y + 40y + 5y = 3150[/tex]
[tex]105y = 3150[/tex]
[tex]y = \frac{3150}{105}[/tex]
[tex]y = 30[/tex]
Then
[tex]x = 3y = 3(30) = 90[/tex]

x = 16
y = 140
Step-by-step explanation:
Since angles on a straight line add to 180°,
(8x + 12) + (3x-8) = 180
8x + 3x + 12 - 8 = 180
11x + 4 = 180
11x = 176
x = 16
Due to the Alternate Interior Angles Theorem,
y = 8x + 12
Substituting 'x=16' into 'y=8x+12':
y = 8(16) + 12
= 128 + 12
= 140
