A = 5
B = 2
C = 10
The slope of the linear equation 5x + 2y = 10 will be negative 5/2.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Consider the line represented by the equation 5x + 2y = 10.
The equation in standard form is given as,
Ax + By = C
Convert the equation into slope-intercept form. Then we have
Ax + By = C
By = -Ax + C
y = -(A/B)x + C/B
The slope of the equation is given as,
m = - A/B
m = - 5 / 2
The slope of the linear equation 5x + 2y = 10 will be negative 5/2.

Ines has saved $5. She doubles the amount she saves each week. Does the function have a constant difference or a constant ratio? Does this represent an exponential function?
Answer:
The function have a constant ratio
No, it does not represent an exponential function.
Step-by-step explanation:
As given,
Ines has saved $5. She doubles the amount she saves each week.
⇒ In first week she saved = $5
In second week she saved = 2×$5 = $10
In third week she saved = 2×$10 = 20
In fourth week she saved = 2×$20 = 40
and so on..
∴ we get the series
5, 10, 20, 40 ,.......
If the series is given as a, b, c, d, ..... , then
The common difference is defined as d = b-a = c-b
The common ration is defined as r = \(\frac{b}{a} = \frac{c}{b}\)
Here, in the given question
The series is - 5, 10, 20, 40
This has no common difference , d = 10 - 5 (= 5 )≠ 20 - 10 (= 10)
As 5 ≠ 10
So the function does not define common difference .
Now,
This has common ratio , r = \(\frac{10}{5} (=2) = \frac{20}{10}(=2)\)
As 2 = 2
So, the function represent common ratio
Now,
The function does not represent an exponential function because it is increased by common ratio.

the table above shows shipping charges for an online retailer that sells sporting goods. there is a linear relationship between the shipping charge and the weight of the merchandise. which function can be used to determine the total shipping charge f( )x , in dollars, for an order with a merchandise weight of x pounds?
The linear equation for the given situation is f(x) = 0.99x + 11.99
The correct answer is:
B) f(x) = 0.99x + 11.99
To determine the function that relates the merchandise weight to the shipping charge, we can use the given data points to find the slope and y-intercept of the linear relationship.
The general form of a linear equation is:
f(x) = mx + b
Where:
f(x) is the shipping charge (y-axis)
x is the merchandise weight (x-axis)
m is the slope of the line
b is the y-intercept
Using the given data points (5, 16.94) and (10, 21.89), we can calculate the slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (21.89 - 16.94) / (10 - 5)
= 4.95 / 5
= 0.99
So, the slope (m) is 0.99.
Next, let's use one of the data points (let's use the first one: 5, 16.94) to solve for the y-intercept (b):
16.94 = 0.99 × 5 + b
b = 16.94 - 4.95
b = 11.99
So, the y-intercept (b) is 11.99.
Now we have all the information we need to write the linear equation in the form f(x) = mx + b:
f(x) = 0.99x + 11.99
The correct answer is:
B) f(x) = 0.99x + 11.99

The given problem involves a machine that issues lottery tickets and experiences breakdowns at different frequencies. The costs associated with repairs and preventive maintenance options are provided.
To find the most cost-effective option, we need to compare the total costs of each option considering the frequency of breakdowns. Option #1 covers all repairs for a fixed cost of $500, regardless of the number of breakdowns. Option #2, on the other hand, charges $360 for the first repair and any subsequent repairs, making it more favorable for machines with a higher frequency of breakdowns.
To calculate the total costs, we multiply the frequency of breakdowns by the repair cost for each occurrence and sum them up. For option #1, the total cost is obtained by multiplying the frequency of each breakdown by $500 and summing them. For option #2, we calculate the total cost as the sum of $360 plus the product of the frequency of breakdowns after the first one and $230 (average repair cost).
After performing the calculations, we can compare the total costs of both options and choose the option with the lowest cost. The chosen option will provide the most cost-effective preventive maintenance for the machine issuing lottery tickets.

Find an equation for the perpendicular bisector of the line segment whose endpoints

Answer:

Step-by-step explanation:
Mike used of a cup of vinegar in his salad dressing recipe. He made 3 salad dressing recipes. Between which two whole numbers does the number of cups of vinegar that Mike used lie?
The number of cups of vinegar that Mike used lies between the whole numbers 2 and 4
If Mike used one cup of vinegar for each salad dressing recipe, then he used a total of 3 cups of vinegar (1 cup x 3 recipes = 3 cups).
However, the question states that he used "a cup of vinegar" in each recipe, which could mean that he used slightly less than one cup, exactly one cup, or slightly more than one cup.
Assuming that Mike used at least 3/4 cup of vinegar in each recipe (which is still close to "a cup"), then he used a minimum of 2 and 1/4 cups of vinegar in total (3/4 cup x 3 recipes = 2 and 1/4 cups).
Assuming that Mike used at most 1 and 1/4 cups of vinegar in each recipe (which is still close to "a cup"), then he used a maximum of 3 and 3/4 cups of vinegar in total (1 and 1/4 cups x 3 recipes = 3 and 3/4 cups).

The MD has placed an order for 15mg of albuterol and 0.5mg of atrovent to be given over one hour. The nebulizer you use has an output of 10ml oer hour when running at 4lmp. How much saline would you need to add to your medication to make it last the full hour?
The volume of the medication required, we subtract it from the nebulizer output to find the amount of saline needed.
To determine the amount of saline needed to make the medication last the full hour, we need to calculate the total volume of medication required and subtract it from the volume delivered by the nebulizer.
Given:
- Albuterol dose: 15 mg
- Atrovent dose: 0.5 mg
- Nebulizer output: 10 mL per hour
- Nebulizer flow rate: 4 LPM (liters per minute)
First, we need to convert the nebulizer flow rate to mL per hour:
4 LPM * 60 min = 240 mL per hour
Next, we calculate the total volume of medication required by adding the doses of albuterol and Atrovent:
Total medication volume = 15 mg + 0.5 mg
Now, we need to convert the total medication volume from milligrams to milliliters. To do this, we need to know the concentration of the medication (mg/mL) or the volume of the medication that corresponds to the given dose. Without this information, we cannot convert the dose to volume accurately.

I think its 7x7 because it equals to 49 and its the closest to 50 and the rug would fit better than 6x 8 1/2=51 becuase 49 is smaller and would fit better.
Step-by-step explanation:
The area of a 2D form is the amount of space within its perimeter. The correct option is B, 8ft diameter.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since Courtney and Malik want the rug to fit in an area of 50-square-foot space. Therefore, we need to first calculate the area of the given rugs, and then choose the one that can completely cover the area.
7 ft x 7 ft → Area = 7 ft x 7 ft = 49 ft²8 ft diameter → Area = (π/4)×Diameter² = (π/4)×(8ft²) = 50.2654 ft² 6 ft x 8ft → Area = 6 ft x 8ft = 48 ft²Now, as it can be seen that the only rug that can completely cover the 50-square-foot area is the one that has a diameter of 8 ft.

20 inch (diameter) bicycle wheel is spinning at a rate of 150 rpm. how fast is the bicycle moving (in mph)?
The bicycle is moving at a speed of 14,356 meters per hour.
Here, we are given that the wheel of a bicycle is spinning at the rate of 150 revolutions per minute.
The diameter of the wheel is 20 inches
⇒ radius = 10 inches
⇒ circumference of the wheel = 2 × π × 10
= 20π
Thus, the wheel will cover a distance of (20π × 150) inches in a minute
= 300π
now, we know that 1 inch = 0.254 meters
⇒ 300π inches = 300π × 0.254
= 76.2π
Thus, the bicycle covers 76.2π meters in a minute
⇒ it'll cover 76.2π × 60 meters in an hour
= 4572π

six witches and ten sorcerers are at an arcane mixer. the witches have decided to shake hands with each of the sorcerers. none of the witches bothered to shake each other's hands, since they are all good friends already, and the sorcerers all sort of hate each other and did not shake hands with other sorcerers. how many handshakes took place at the mixer?
The total number of handshakes is equal to the number of combinations of n people taken two at a time.
To find the solution of this problem, we can apply the formula for calculating the total number of handshakes,
that isn: where n is the number of people who shake hands. Here, six witches will shake hands with ten sorcerers. So, the total number of handshakes can be given as follows:
n = 6 + 10 = 16
∴Total number of handshakes = nC2= (16 C 2) = 120So, there were 120 handshakes took place at the mixer.
We use the nC2 formula because the number of handshakes between two people is independent of the number of handshakes of other people.

Assume the probabilities of a child being allergic to the following foods are as follows:
.014 for nuts
.043 for dairy
.031 for gluten
Calculate the probability that a child is NOT allergic to nuts.
The probability that a child is not allergic to nuts is 0.986, or 98.6%.
The probability that a child is not allergic to nuts can be calculated by subtracting the probability of being allergic to nuts from 1.
Given the probabilities of a child being allergic to nuts, dairy, and gluten, we are interested in finding the probability that a child is not allergic to nuts.
The probability of being allergic to nuts is given as 0.014.
To find the probability that a child is not allergic to nuts, we subtract this value from 1.
P(Not allergic to nuts) = 1 - P(Allergic to nuts) = 1 - 0.014 = 0.986
Therefore, the probability that a child is not allergic to nuts is 0.986, or 98.6%.
This calculation is based on the assumption that being allergic to nuts and being allergic to other foods are independent events.
