(a) The HCF of ( 9y + x ) and ( 3y + 4x ) is 11x
b) The LCM of ( 9y + x ) and ( 3y + 4x ) is 22x.
The ratio of x and y is given as:
x : y = 3 : 7
Then,
(x / y) = ( 3 / 7)
7x = 3y
(a) HCF of ( 9y + x) and ( 3y + 4x)
Now,
9y + x = 3(3y) + x
9y + x = 3(7x) + x
9y + x = 22x
And;
3y + 4x = 7x + 4x
3y + 4x = 11x
Now, the HCF of 22 and 11 is 11 because 22 = 2 × 11 and 11 = 11 × 1.
Therefore,
HCF of ( 9y + x ) and ( 3y + 4x ) is 11x.
(b) The LCM of (9y+x) and (3y+4x)
We know,
9y + x = 22x and 3y + 4x = 11x
So, LCM of ( 9y + x ) and ( 3y + 4x ) is 22x.

How much external financing will Tobin Supplies Company have to seek? Assume there is no increase in liabilities other than that which will occur with the external financing.
The amount of external financing Tobin Supplies Company have to seek assume there is no increase in liabilities other than that which will occur with the external financing is $58,250
What is the appropriate formula for external financing?
The formula that models the amount of external financing Tobin supplies company requires is a function of its increase in assets minus the retained earnings which would be used to part-fund the increase in assets
external funds needed=increase in assets-retained earnings
increase in assets=$105,000
retained earnings=net income-dividends
net income=sales*profit margin
net income=$550,000*10%

Aisha just received a $40 paycheck from her new job. She spends some of it buying music online and saves the rest in a bank account. Her savings is given by f(x)=40-1.25x, where x is the number of songs she downloads at $1.25 per song. Graph the function.
The graph of saving function f(x) = 40 - 1.25x has been plotted with a slope of -1.25.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
Given the function,
f(x) = 40 - 1.25x
Now to plot it we need to put x = 0
f(0) = 40 so y-intercept is (0,40)
Now keep f(x) = 0
Then 0 = 40 - 1.25x
x = 40/1.25 = 32
So x-intercept is (32,0)
So plot a straight line using points (0,40) and (32,0).
Hence "The graph of saving function f(x) = 40 - 1.25x has been plotted".

In the figure below, h

Applying the same-side-interior angles theorem, the values are:
x = 95°
z = 35
What is the Same-Side-Interior Angles Theorem?An examples of angles that are referred to as same-side-interior angles are x° and 85°.
According to the same-side-interior angles theorem, the sum of x and 85 will give 180 degrees if lines h and o are parallel to each other.
Since h║o, therefore:
x + 85 = 180
x + 85 - 85 = 180 - 85
x = 95°
(6z - 115)° and x° are vertical angles, therefore:
6z - 115 = x
Plug in the value of x
6z - 115 = 95
6z - 115 + 115 = 95 + 115
6z = 210
6z/6 = 210/6
z = 35

how do you solve
7 - 5/7 =
Step-by-step explanation:
by bringing all terms to the same fractions (with the same denominator).
so, we have
7
5/7
that means we want to bring both numbers to .../7 form.
7 means 7 whole units.
1 whole unit has now many parts ?
if we aim for 2 parts, that makes 1 whole unit 2/2.
if we aim for 3 parts, 1 whole unit is 3/3.
...
you see, 3/3 = 1/1 = 1.
that is the whole trick.
so, we are looking for 7 parts, and 1 whole unit is 7/7.
now we have 7 whole units.
how many parts are those ?
well, 7 × 7/7 = 49/7
there we go.
we have
7 - 5/7 = 49/7 - 5/7 = 44/7 = 42/7 + 2/7 = 6 2/7
The average worker in a manufacturing plant produces 27 units every hour the manager of the plant took a sample of 25 workers and gave them special training designed to increase their productivity after the special training was complete the 25 workers produced 28.2 units every hour with stand deviation of 2.9 what is the probability of randomly sampling 25 workers from the general population and their mean productivity being 28.2 or higher
The probability of randomly sampling 25 workers from the general population and their mean productivity being 28.2 or higher is 0.0192.
How to illustrate the information?It should be noted that from the information, after the special training was complete the 25 workers produced 28.2 units every hour with stand deviation of 2.9.
Therefore, the probability of randomly sampling 25 workers from the general population and their mean productivity being 28.2 or higher will be:
= 1 - P[(Z (28.2 - 27)/29/✓25)]
= 1 - P(Z < 2.07)
It should be noted that this will be looked on the distribution table.
= 1 - 0.9808
= 0.0192
Therefore, the probability of randomly sampling 25 workers from the general population and their mean productivity being 28.2 or higher is 0.0192.

This is the graph of y= x2 + 4x + 7 what is the range of this function?
The range of the function y = x^2 + 4x + 7 is y >= 3
How to determine the range of the function?The equation of the function is given as
y = x^2 + 4x + 7
Start by differentiating the above function
So, we have
y' = 2x + 4
Set the above equation to 0
So, we have
2x + 4 = 0
Divide through the equation by 2
So, we have
x + 2 = 0
Evaluate the like terms:
x = -2
Substitute x = -2 in y = x^2 + 4x + 7
y = (-2)^2 + 4(-2) + 7
Evaluate the expression
y = 3
The leading coefficient of the equation y = x^2 + 4x + 7 is positive
This means that the vertex is a minimum
So, the range is
y >= 3
Hence, the range of the function y = x^2 + 4x + 7 is y >= 3

Solve for all values of x in simplest form
Answer:
x = √(5) - 8
x = -√(5) - 8
Step-by-step explanation:
Let's solve the problem,
→ (x+8)² - 43 = -38
→ x² + 64 - 43 = -38
→ x² + 21 = -38
→ x² = -38 - 21
→ x = √(-59)
→ [ x = √(5) - 8 ]
(or) [ x = -√(5) - 8 ]

Write and solve an absolute value equation to find the least and greatest
possible temperature if the thermometer reads 87.4° F.
The required absolute value equation is |x - 87.4| = 1.5
Also, if the thermometer reads 87.4° F, the least possible temperature is 85.9° F and the greatest possible temperature is 88.9° F
In this question, the thermometer is accurate within 1.5 degrees of the actual temperature in degrees Fahrenheit.
We need to find the least and greatest possible temperature if the thermometer reads 87.4° F
Let x be the temperature in degrees Fahrenheit.
From given information, an absolute value equation would be,
|x - 87.4| = 1.5
We know that, | ±a | = a
x - 87.4 = ±1.5
Case 1: x - 87.4 = 1.5
x = 1.5 + 87.4
x = 88.9° F
Case 2: x - 87.4 = -1.5
x = -1.5 + 87.4
x = 85.9° F
Therefore, the required absolute value equation is |x - 87.4| = 1.5
Also, if the thermometer reads 87.4° F, the least possible temperature is 85.9° F and the greatest possible temperature is 88.9° F
