Each day a small business owner sells 200 pizza slices at $2.50 per slice and 85 sandwiches at $2.00 each. Business
expenses come to $60 per day. What is the owner's profit for a ten-day period?
The profit is S
The owner's profit for a ten-day period is equal to $ 6100.
We are given that:
Selling price of 1 pizza slice = $ 2.50
Number of pizza slice sold per day = 200
Selling price for pizza slices in a day = 200 × $ 2.50
SP ( pizza ) = $ 500
Selling price of 1 sandwich = $ 2
Number of sandwich sold per day = 85
Selling price for pizza slices in a day = 85 × $ 2
SP ( sandwich ) = $ 170
Selling price in 1 day = $ 500 + $ 170 = $ 670
Now, Cost price in 1 day = $ 60
Profit in 1 day = $ 670 - $ 60 = $ 610
Profit in 10 days = 10 × $ 610 = $ 6100
Therefore, the owner's profit for a ten-day period is equal to $ 6100.

Answer:
350p2+19500p-199000
(The first term is actually -350p² but I guess you have to write it as -350p2)
Step-by-step explanation:
Looks like that first term in the revenue equation is -350p²
We have
E = -1500p + 199000
R = -350p² + 18000p
Profit = Revenue - Expenses = R - P
Profit = -350p² + 18000p - (-1500p + 199000)
= 350p² + 18000p + 1500p - 199000
= 350p² + 19500p - 199000

What price do farmers get for their watermelon crops? in the third week of july, a random sample of 40 farming regions gave a sample mean of x bar = $6.88 per 100 pounds of watermelon. assume that is known to be $2.00 per 100 pounds.
We have given a sample size of n=40
Sample mean ¯x=$6.88 per 100 pounds
Population standard deviation= 1.96 per 100 pounds
First, we need to find the value of z α /2 =z (1−0.90/2)
Z (α/2) =z0.05
Z (α/2) =1.645
(a)The required 90% confidence interval is;
¯x ± margin of error
¯x ± z (α/2) * σ/sqrt 40
6.88 ± 1.645 * 1.96/sqrt 40
6.88±0.5097
(6.38,7.38)
Therefore, the lower limit is $6.38 per 100 pounds.
The upper limit is $7.38 per 100 pounds.
The margin of error is 0.50 per 100 pounds.
(b) to have the maximum of E, we use the formula;
n= (z (α/2)×σ/E) ^2
n= (1.645× (1.96/0.41)) ^2
n=61.84≈62
Therefore, the required farming region will be 62.

An object is moving at a speed of 63 centimeters every 2 days. Express this speed in meters per hour.Round your answer to the nearest hundredth.
This speed in meters per hour is 0.01 meter per hour
How to determine the speed?The given parameter is
Speed = 63 centimeters every 2 days
Divide 63 by 2
So, we have:
Speed = 31.5 centimeters every day
There are 24 hours in a day
So, we have
Speed = 31.5 centimeters every 24 hours
100 cm equals 1 m
So, we have:
Speed = 0.315 meters every 24 hours
Divide
Speed = 0.013125 meter per hour
Approximate
Speed = 0.01 meter per hour
Hence, this speed in meters per hour is 0.01 meter per hour

Small, random genetic changes that occur over generations is known as _________.
Small, random genetic changes that occur over generations is known as genetic drift.
What is genetic drift?Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population. The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.
Some people might merely by coincidence leave behind a few more offspring (and genes, of course!) than others in each generation. The next generation's DNA and other genetic components will come from the "fortunate" people, not necessarily the healthier or "better" people.

The Transitive Property states that if a=b and b=c, then a=c. Explain how you can use the Transitive Property to show that the expressions 0 + x + 13 and 13 + x are equivalent.
According to transitive property, 0 + x + 13 = x + 13 and also x + 13 is equal to 13 + x. Thus, we can equally say that; 0 + x + 13 is equal to 13 + x
How to Interpret Transitive Property?
We are told that the Transitive Property states that if a = b and b = c, then a = c.
Now, if a = 3 for example, then by the transitive property, it means that b and c must both also be 5.
Now, we want to apply the the transitive property to show that the expressions 0 + x + 13 and 13 + x are equivalent.
Now, the expression 0 + x + 13 is equal to x + 13.

What is the equation of the line that is parallel to the given line and passes through the point (–2, 2)?
A. y=1/5x+4
B. y=1/5x+12/5
C. y=-5x+4
D. y=-5x+12/5
The slope of the line shown is 1/5, and being parallel means having the same slope. So it’s either a or b.
Next, you plug in (-2, 2) into y=1/5x+b to find b.
Solving you get: 2=1/5 * -2 +b
2=-2/5+b
B=2 2/5
12/5 = 2 2/5

add 7.5m, 2.25 and 50cm and give results in metres
The sum of the three values is 10.25 meters.
Here, we are given three measurements- 7.5m, 2.25m and 50cm
Since, we need to find the answer in meters, let us convert all the units to meters so that we can add them.
7.5 and 2.25 are already in meters so we do not need to covert them.
We only need to convert 50 centimeters.
As per mathematical conversions,
1 meter = 100 centimeters
This means that 50 centimeters will be,
100/2 centimeters = 1/2 meters
⇒ 50 centimeters = 0.5 meters
Now, we add all the given numbers,
= 7.5 + 2.25 + 0.5
= 9.75 + 0.5
= 10.25
Thus, the sum is 10.25 meters.

Using the fact that the two angles are complementary, the we will find that the measures are:
∠1 = = 14°
∠2 = 76°
How to find the measures of the angles?
By looking at the diagram, we can see that the sum of the measures of angles 1 and 2 must be equal to 90° (this means that the two angles are complementary).
We also can see that:
∠1 = x - 5
∠2 = 4x
Then we can solve the linear relation:
(x - 5) + 4x = 90
x - 5 + 4x = 90
5x - 5 = 90
5x = 90 + 5 = 95
x = 95/5 = 19
Then the measures of the two angles are:
∠1 = (x - 5)° = (19 - 5)° = 14°
∠2 = 4x = 4*19° = 76°

{-3x+10y=55
A statement that explains the equation 13x - 13y = -26 shares a solution with given system of equations because 13x - 13y equals 55.
What is defined by system of equations?Linear equations (those that graph as straight lines) are easier to solve than non-linear equations, as well as the simplest linear system has two equations and two variables.The equation system is presented below;
10x - 3y = 29 .........equation 1
-3x + 10y = 55 ..........equation 2
As a result of subtracting equation (2) from equation (1), we get;
By subtracting equivalent expressions, (10x - 3y) - (-3x + 10y) = 29 - 55.
13x - 13y = 29 - 55 = -26
Provided that the operation on equations (1) and (2) is the same, the given equation is 13x - 13y = -26.
We can see from the subtraction of equivalent representations that the solution for the
The solution for given equation, 13x - 13y = -26, is like the solution for given equation.
The reason why 13x - 13y = -26 has the same solution as the system of equations is that -3x + 10y is equal to 55, so we can subtract -3x + 10y from the left side of 10x - 3y = 29 and subtract 55 from the right side.
Thus, subtracting equivalent representations from each side of the an equation has no effect on the equation's solution.

2x - 5 < 2x - 6
now when we simplify the inequality 2x on the both sides will be eliminated and we will be left with:

Number of train rides to make the frequent-rider pass a better deal than standard train tickets is 26 or more rides.
As given,
Cost of standard train ticket = 3 per ride
Price of frequent rider pass= 18.75 each month
Cost of ticket using rider pass = 2.25 per ride
let x be the number of rides
Equation:
18.75 + 2.25x < 3x
⇒ 0.75x > 18.75
