please help me please
Answer:
For the first one
Part a:
115x + 685y >= 2300
Part b:
See explanation below
Second one:
1.5x + 1.0y >= 2000
Rest of explanation below
Step-by-step explanation:
First one.
Let x be the number of skimboards sold and y be the number of longboards sold.
Then revenue from sales of x units at $115 and y units at $685 would be
115x + 685y
This must be at lest the overhead to make zero loss
So the inequality is
115x + 685y ≥ 2300 (Answer a)
Part b
Any combination of x and y which satisfies this inequality will provide a profit. I have provided a graph of this inequality using an online graphing calculator. I am not sure what your teacher wants you to use.
Any point in the shaded region represents a combination of x and y which satisfies that inequality. However since you cannot sell a fraction of a surfboard, only points which represent whole numbers can be valid. Also only values of x and y >=0 can be chosen. So any point in the shaded region which has x and y non-negative and x and y whole numbers will generate a profit
Again I am not sure whether this question is asking for a specific value or possible values.
A specific value can be (x=5, y = 10) which is well within the shaded region. This represents 5 skimboards and 10 longboards with a revenue of 5 x 115 + 10 x 685 = $ 7425
Or you could sell 0 skimboards and 4 longboards giving you a revenue of
4 x 685 = $2,740
Or 20 skimboards and zero long boards which is a revenue of $2300 which breaks even with the overhead
Second Question: Modeling

Caleb is buying a new bed costing £400. He pays of the total cost when he orders the bed and the rest on delivery. How much does he pay when he orders the bed?
Caleb pays £80 when he orders the bed
How to determine how much he pays when he orders the bed?From the question, we have the following parameters that can be used in our computation:
Total cost of the bed = £400
Proportion paid when ordering the bed = 1/5
Using the above as a guide, we have the following:
Amount paid when ordering the bed = Proportion paid when ordering the bed * Total cost of the bed
Substitute the known values in the above equation, so, we have the following representation
Amount paid when ordering the bed = 1/5 * £400
Evaluate the products
So, we have the following representation
Amount paid when ordering the bed = £80
Hence, the amount is £80

in how many ways can four people sit in six chairs so that the leftmost chair is occupied and the right most is not
There are 96 ways for four people to sit in six chairs so that the leftmost chair is occupied and the rightmost is empty.
There are 4 guests and the leftmost seat is to be occupied, so there are 4 such ways to choose the occupant of that seat.
Then, for each of those 4 ways, there are 4 ways to decide the occupant for the second seat -- the remaining three people plus the possibility of that seat being empty, that makes a total of 16 ways to decide the configuration of the first two seats.
Then, for each of those 16 ways, there are 3 ways to choose the occupant for the third seat (either 3 remaining guests if the second seat was left empty, or the two remaining guests plus the possibility of leaving the 3rd seat empty). Hence, 16 times 3 is 48. For each of those ways, there are two choices for the next seat, i.e. 48 times 2 = 96, and finally one choice for the fifth seat. So in all, there are 96 ways.

A quadrilateral has 4 sides. one angle of a regular quadrilateral measures (6w 13)°. determine the value of w. round to the nearest whole number. w = 13 w = 23 w = 59 w = 90
A regular quadrilateral is one in which the lengths of all the sides and the measures of all the angles are equal. A regular quadrilateral must have all of its angles measured (6w 13°) if one of its angles does.
A quadrilateral's angles measure a total of 360 degrees. The total measure of the angles of a regular quadrilateral is 4 (6w 13)°, which equals 24w + 52°. A regular quadrilateral contains four angles, of which each measure (6w 13)°. Thus, we obtain the equation shown below:
24w + 52° = 360°
Solving for w, we get:
24w = 308°
w = 13
Consequently, w has a value of 13, and w = 13 is the right response.

If May is 15 and John is five years older than may and Jay is 15 years older than John. How old is Jay?
Answer:
Jay is 35
Step-by-step explanation:
Creating an equationLet:
x = age of mayy = age of john z = age of jayHere, we are given that
May is 15 so x = 15John is 5 years older than may or y = x + 5 Jay is 15 years older than john or z = y + 15Solving for the agesGiven that x = 15 , y = x + 5 and z = y = 15
We can firstly find the age of john or "y" as we are given the value of x
y = x + 5
==> plug in x = 15
y = 15 + 5
==> add 15 and 5
y = 20
So John is 20
Now that we have the value of y we can easily find Jay's age or the value of z
z = y + 15
==> y = 20
z = 20 + 15
==> add 20 and 15
z = 35
Hence, Jay is 35

find three vectors with which you can demonstrate that the vector cross product need not be associative, i.e., that a x (b x c) need not be the same as (a x b) x c. g
The cross product of three vectors is not associative in nature.
Considering three vectors such as : A=(2,1,3), B=(1,0,2) and C=(1,1,0)
we know that the associative law depicts that :
A x (B x C) = (A x B) x C ,while doing the operation for the considered vectors :
A x (B x C) =(2,1,3)x ((1,0,2)x (1,1,0))
=(2,1,3)x (-2,2,1)
=(-5,-8,6)
(A x B) x C= ((2,1,3)x (1,0,2))x (1,1,0)
= (2,-1,1) x (1,1,0)
=(-1,1,3)
So for this vector operation, A x (B x C) is not equal to (A x B) x C, so you can sum up that cross product of three vectors can't be associative every possible time.

Of the 47 plays attributed to a playwright, 11 are comedies, 20 are tragedies, and 16 are histories. If one play is selected at random, find the odds against selecting a history
The odds against selecting a history are 31/16.
Define probability.Probability is the concept that describes the likelihood of an event occurring. In many situations, it is necessary to foresee how something will turn out in the actual world. We may be aware of the result of an event or not. When this occurs, we state that there is a possibility that the event will occur.
Probability is the ratio of the most likely outcomes to all other possible outcomes of an event. The number of successful outcomes for an experiment with 'n' outcomes may be expressed using the symbol x. The following formula can be used to determine the likelihood of an event.
Probability(Event) = favorable outcome/Total outcome = x/n
Number of playwrights = 47
Number of histories = 16
Therefore, the odds against selecting a history are

What is sample proportion?Sampling is frequently used to estimate the percentage of population that possesses a particular attribute, such as the percentage of all faulty goods which come off an assembly line or the percentage among all buyers that enter a store and make a purchase before leaving. The population proportion is indicated p, while the sample proportion is written p. Thus, if 43% of individuals visiting a business make a purchase before departing, p = 0.43; if 78 people enter the store and make a transaction, p=78/200=0.39.
The sample proportion is a random variable because it differs from sample to sample in ways that are impossible to anticipate in advance. When seen as a random variable, it will be represented by the letter P.
How to solve?
An article reported that in a study of a particular wafer inspection process, 356 dies were examined by an inspection probe and 169 of these passed the probe.

Bill wanted to try out different water craft. he went 62 miles downstream in a motor boat and 27 miles downstream on a jet ski. his speed on the jet ski was 10 mph faster than in the motor boat. bill spent a total of 4 hours on the water. what was his speed in the motor boat?
The speed of the bill's motor boat is found as 20 mph.
Explain the relation of speed and time?The speed and time relationship is inverse. Distance / time equals speed. If you keep the distance constant, speed rises as time goes down and falls as it goes up.Here, we're trying to determine the motorboat's speed.
The speed on the skis would be (x + 10) mph if his motorboat speed is x mph.
There are four hours in all;
Speed = distance/time mathematically.
Skiing time is 27/x+10.
The motorboat time is 62/x.
The result of adding both is 4.
Thus;
27/(x + 10) + 62/x = 4
27(x) + 62(x + 10) = 4(x)(x + 10)
27x + 62x + 620 = 4(x² + 10x)
89x + 620 = 4x² + 40x
4x² -49x-620 = 0
By the quadratic formula;
{-b ± √(b²-4ac)}/2a
In which a = 4, b = -49 and c = -620
= 49 ± √(-49)² -4(4)(-620)/8
Thus,
49+ 111/8 or 49-111/8
As, speed is not negative.
= (49 + 111)/8
= 20 mph
Thus, the speed of the bill's motor boat is found as 20 mph.
