Answer: 1  5/12

Step-by-step explanation: You need to find a common denominator 3 and 4 are the denominators you can do 3 times 4 is 12 and 4 times 3 is 12, but whatever you do to the denominator needs to be done to the numerator so 2 times 4 is 8 and 1 times 4 is 4 then you have the fractions 8/12 and 3/12 then you just subtract and you get 1  5/12.

Answer:

$142500

Step-by-step explanation:

We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.

If the sum of the two salaries is $190000, we are to find the salary of the president of the University.

Let [tex]x[/tex] to be the department head's salary, we can write an equation:

[tex]3x+x=190000[/tex]

[tex]4x=190000[/tex]

[tex]x=47500[/tex]

Salary of the president of the University = [tex]3(47500)[/tex] = $142500

Answer:

$142,500

Step-by-step explanation:

Let's say x is the salary of the department head.... so the salary of the president of the university can be described as 3x.

Then, we know the total of the two salaries is 190,000.  We can express this as:

3x + x = 190,000

4x = 190,000

x = 47,500

x is for the department head.  To get the president's salary, we have to multiply that by 3:

p = 3 (47,500) = 142,500

The salary of the president is then of $142,500.

The function rule for the situation is none of the given options

From the question, we have the following parameters that can be used in our computation:

Membership = $20

Payment each time = $300 per visit

using the above as a guide, we have the following:

f(x) = Membership + Payment each time * x

substitute the known values in the above equation, so, we have the following representation

f(x) = 20 + 300* x

Evaluate

f(x) = 20 + 300x

Hence, the expression is f(x) = 20 + 300x

none of the given options

None of the provided options in the question are correct.

The function rule that correctly represents Rex's situation, given that he paid a $20 membership fee and pays $300 each time he goes to the pool, would be a linear equation that includes a one-time fee (membership) and a per-visit cost. Let's define x as the number of times Rex goes to the pool and y as the total cost. Therefore, the equation should include the initial membership fee and the per-visit cost multiplied by the number of visits.

The correct function rule is y = 20 + 300x, where 20 represents the one-time membership fee and 300 represents the cost per pool visit. None of the provided options are correct. The equation signifies that for every visit to the pool, the total cost increases by $300, and the initial membership cost is $20.

sin=√17/7

or sin=sqrt(17)/7

Answer:

[tex]\frac{\sqrt{17} }{7}[/tex]

Step-by-step explanation:

Given

cosΘ = [tex]\frac{4\sqrt{2} }{7}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

Then the hypotenuse of the right triangle is 7 and the adjacent side is 4[tex]\sqrt{2}[/tex]

To find the opposite side use Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

opp² + (4[tex]\sqrt{2}[/tex] )² = 7²

opp² + 32 = 49 ( subtract 32 from both sides )

opp² = 17 ( take the square root of both sides )

opp = [tex]\sqrt{17}[/tex]

Hence

sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{\sqrt{17} }{7}[/tex]

$0.13 per ounce.  5 pounds of birdseed cost $10.40, then the price per ounce is $0.13.

The easiest way to solve this problem is using arithmetic operations and unit conversion.

We have to calculate the price per pound. Let's divide $10.40 by 5 pounds.

10.40/5 = 2.08

The price per pound is $2.08

To calculate the price per ounce, with 1 pound = 16 ounces. Let's divide $2.08 by 16 ounces.

2.08/16 = 0.13

The price per ounce is $0.13

Answer:

For number 14, the answer should be 100 degrees. For number 15, the answer is 80 degrees. For number 16, the answer is 120 degrees.

Step-by-step explanation:

For number 14, if a minor arc is 80 degrees, then the major arc should be 100 degrees to add to make 180 degrees. For number 15, you can see the size of the 70 degrees angle, AB. Because DE is bigger than AB, we can conclude that it is probably 80 degrees. For number 16, if XY, YZ, and ZX are all the same, and a circle always adds up to 160 degrees, then 360 divided by the three arcs is 120.

Final answer:

The quadratic equation with roots -2/5 and 7/5 is 25x^2 - 25x - 14 = 0. This is derived by expressing the equation in the form a(x - α)(x - β) = 0 and substituting the given roots.

Explanation:

To find a quadratic equation with roots -2/5 and 7/5, we use the fact that if α and β are the roots of the quadratic equation ax2 + bx + c = 0, then the equation can be written as a(x - α)(x - β) = 0. For roots -2/5 and 7/5, the quadratic equation becomes:

x2 - (sum of roots)x + (product of roots) = 0

x2 - ((-2/5) + (7/5))x + ((-2/5) × (7/5)) = 0

x2 - (5/5)x - (14/25) = 0

x2 - x - 14/25 = 0

Multiplying through by 25 to clear the fraction:

25x2 - 25x - 14 = 0

This is the quadratic equation with the given roots.

Answer:

A. How can the equation be used in temperature conversion?

You take the conversion equation C = (5/9) (F - 32) and you replace the F by the value of Fahrenheit degrees...  then solve the calculations to get the degrees in Celsius.

For example, if you have 80°F to convert in °C:

C = (5/9) (80 - 32) = (5/9) (48) = 26.66 °C

B. How can you use the graph to find the body temp in C?

Using the graph will give a very imprecise measure due the scale of the graph.

But you would have to find 98.6 on the axis of X (it represents the °F), then go upwards until you find the line....

Then report that position on the line on the Y-axis (representing the °C) to get your measure.

Answer:

For A: The linear equation is [tex]C=\frac{5}{9}F-\frac{32}{9}[/tex]

For B: The temperature of normal body in degree Celsius is 37° C.

Explanation:

Linear equations are defined as the equations in which the highest power of a variable is '1'. The general equation for a linear equation is:

[tex]y=mx+c[/tex]

where,

y = Y-coordinate

m = slope of the line

x = X - coordinate

c = intercept on y-axis

For the given equation:

[tex]C=\frac{5}{9}(F-32)[/tex]

The linear equation representation for the given equation is:

[tex]C=\frac{5}{9}F-\frac{32}{9}[/tex]

We are given a value of temperature in degree Fahrenheit. To calculate its value in degree Celsius, we use the equation above.

Putting value of F = 98.6 in above equation, we get:

[tex]C=(\frac{5}{9}\times 98.6)-\frac{32}{9}\\\\C=37[/tex]

Hence, the temperature of normal body in degree Celsius is 37° C.

Answer

a. [tex]\frac{1}{m}(6)+\frac{1}{12} (6)+\frac{1}{15} (6) =1[/tex]

b. 60hrs

Step-by-step explanation:

Let the time Molli will take to pint the room to be = t

Thus the amount of room that Molli can paint in 1 hour= 1/m

The amount of room John can paint is 1 hour= 1/12

The amount of room Rick can paint in 1 hour = 1/15

The equation for working together at a rate x time per work done will be;

[tex]\frac{1}{m} *6+\frac{1}{12} *6+\frac{1}{15} *6=1[/tex]

You multiply by 6 in the three terms of the equation because it takes 6 hours for John, Rick and Molli to complete painting.

[tex]\frac{6}{m} +\frac{1}{2} +\frac{2}{5} =1[/tex]

multiply by 10m in every part of the expression because 10m is the Least Common Multiple(LCM) is this case

Collect like terms and find value of m

[tex]60+5m+4m=10m\\\\60+9m=10m\\\\60=10m-9m\\\\60=m[/tex]

Molli will take 60 hours to paint the room if working alone

A decrease by 30%, means that the price is now 70% of the original price ( 100% - 30% = 70%)

To find the original price divide the new price by the percent of the original price it is now.

147 / 0.70 = 210

The original price was £210

The price before the decrease is £210.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 147 \div 70\%[/tex]

=  £210

Therefore we can conclude that the price before the decrease is £210.
