We know that division by fraction is the inverse of multiplication. If any number or fraction is divided by a fraction , we multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator.

2. A shop owner raises the price of a $100 pair of shoes by 50%. After a few weeks,
because of falling sales, the owner reduces the price of the shoes by 50%. A
customer then says that the shoes are back at the original price.
a. What is the mistaken assumption here?
b. Why is that assumption incorrect?
c. What do the shoes actually cost now?
d. By what percent should the shoes be decreased in order to have the price
back at $100?
Kk
Answer:
the customer is wrong
Step-by-step explanation:
when he raised then 50 % they became $150 and then If you do the work 50% of $150 is $75 .
100+%50
150
150-%50
75
The customer is wrong because the new price of the shoe is $75 and not $100.
When the shop owner raises the price of a $100 pair of shoes by 50%, then the new price will be:
= $100 + (50% × $100)
= $100 + $50
= $150
Then, the owner reduces the price by 50%, then the new price will be:
= $150 - (50% × $150)
= $150 - $75
= $75
Therefore, the new price is $75.

3. The function E(v)= 15v^2 / 2 models the
kinetic energy E in joules of an object
with a mass of 15 kilograms, where v is
the velocity of the object in meters per
second. Write the inverse function v(E) to
find the velocity of a 15-kilogram object
with kinetic energy E.
Answer:
i think it is 15v (E) = √(2E/m)
Step-by-step explanation:
From the question given:
E = ½mv²
E is the kinetic energy
m is the mass of object
v is the velocity.
To find a model v(E) for the velocity of the object, we simply make V the subject of the above equation.
This can be obtained as follow:
E = ½mv²
Cross multiply
mv² = 2E
Divide both side by m
v² = 2E/m
Take the square root of both side
v = √(2E/m)
Therefore, the model v(E) for the velocity of the object is given by:
v (E) = √(2E/m)
The inverse function v(E) to find the velocity of a 15-kilogram object
with kinetic energy E should be [tex]15v (E) = \sqrt (2E/m)[/tex]
Calculation of the inverse relation:Since we know that
[tex]E = 1\div 2mv^2[/tex]
Here,
E is the kinetic energy
m is the mass of object
v is the velocity.
Now we can write like
[tex]mv^2 = 2E[/tex]
So,
[tex]v^2 = 2E/m[/tex]
Now Take the square root of both side
So,
[tex]v = \sqrt (2E/m)\\\\v (E) = \sqrt (2E/m)[/tex]

What additional information would you need to prove by the HL theorem?
Answer:
Answer: A [tex]\overline{TM}\cong \overline{OR}[/tex]
Step-by-step explanation:
The HL Theorem states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.
Triangles TRO and OMT share the hypotenuse, so the first part of the theorem is met.
Both triangles are right because they have an internal angle of 90°, so the second condition is also met.
Since there is no indication of any leg to be congruent to another leg, we need additional information to prove that both triangles are congruent.
One of these two conditions should be met:
Side TM is congruent to side OR, or
Side MO is congruent to side RT.
From the available options, only the first is correct.
Answer: A [tex]\mathbf{\overline{TM}\cong \overline{OR}}[/tex]
$9000 was borrowed from two sources, one that charges 20% simple interest and the other that charges 5% simple interest. If the total interest at the end of 1 year was $1500, how much money was borrowed from each source?
Answer:
The amount borrowed at 20% simple interest was $7,000, while the amount borrowed at 5% simple interest was $2,000.
Step-by-step explanation:
Let x represents the amount borrowed at 20% simple interest.
Let y represents the amount borrowed at 5% simple interest.
Therefore, the amount borrowed at 5% simple interest will be:
y = 9000 - x ........................... (1)
As a result, we will have:
20%x = interest at the end of 1 year from the amount borrowed at 20% simple interest
5% * (9000 - x) = 450 - 5%x = interest at the end of 1 year from the amount borrowed at 5% simple interest
Since the total interest at the end of 1 year was $1500, we have:
20%x + 450 - 5%x = 1500
We can now solve for x as follows:
20%x - 5%x = 1500 - 450
15%x = 1050
x = 1050 / 15%
x = 7000
Substituting x = 7000 into equation (1), we have:
y = 9000 - 7000
y = 2000
Therefore, the amount borrowed at 20% simple interest was $7,000, while the amount borrowed at 5% simple interest was $2,000.

A university president's salary for the 2012-2013 academic year was $490,000. Calculate his 2013-2014 salary if he received a 2.7% raise
Answer:
His 2013-2014 salary will be $503,230
Step-by-step explanation:
His new salary will be
490,000 + 2.7% of 490,000
= 490,000 + (2.7/100 * 490,000)
= 490,000 + 13,230

The sum of two positive numbers is 37, and their difference is 7. If x and y represent the unknown numbers, which two
equations belong to the system of equations that represents this situation?
Answer:
C & D. check the image just in case the order changes
Step-by-step explanation:
A system of equations is x + y =37 and x - y = 7 the positive numbers are 22 and 15.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The sum of the two positive numbers is 37, and their difference is 7.
Let x and y be the numbers:
x > 0 and y > 0
x + y =37
x - y = 7
The above two equations represent the situation where the sum of two positive numbers is 37, and their difference is 7.
After solving the above equation by elimination method:
2x = 44
x = 22
22 - y = 7
y = 22 - 7
y = 15
Thus, a system of equations is x + y =37 and x - y = 7 the positive numbers are 22 and 15.
