question Today, everything at Nike is on sale. The store offers a 25% discount.
The regular price of a pair of shoes is $125. What is the discount price?
Answer:
$93.75
Step-by-step explanation:
First step, we need to find 25% of 125, we can do this by multiplying .25 by 125. This leaves us with $31.25. Now, we subtract 31.25 from 125, this leaves us with $93.75. There is your answer. Another way to do this is to find 75% of 125 because 25+75 equals 100.

Step-by-step explanation:
Alright, archtan /
tan
−
1
(
x
)
is the inverse of tangent. Tan is
sin
cos
. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.
Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.
Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.
Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

In two or more complete sentences, explain the theorem used in solving for the range of possible lengths of the third side, AB of ABC.
Answer:
Step-by-step explanation:
You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²) b = 9.16
With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10
a(7x+3)=14x+b
What are the values of A and B?
Answer:
24

Jeremy opened a bank account depositing $1,950 initially. He withdraws a fixed amount every month. At the end of the first month, account balance is $1,800. Which equation could model the situation?
Answer:
1800 = 1950 - m
Step-by-step explanation:
Lets call the fixed amount he withdraws every month m. He starts with $1950 and withdraws a certain amount, m, every month. At the end of the first month, he has withdrawn 1m amount of money and ends up with $1800. Therefore, 1950 - 1m = 1800. We can get rid of the 1 and get 1950 - m = 1800, or 1800 = 1950 - m. If the answer choices do not have "m" as a variable, you can substitute "m" for any variable.
can you help with this? and explain.
Answer:
C
Step-by-step explanation:
Answer:
C. x < -175
Step-by-step explanation:
-1/5x + 4 < 39
minus 4 on both sides
= -1/5 < 35
multiply by -5 because we want the X to be positive, always. And when we multiply or divide by a negative number, the sign will always flip.
X > -175

Help questions 1, 3, 4 and 8 please? It’s due In 30 mins
Answer:
For number one I forget what it is called but I know that its not right because the left side can't be connected to 2 numbers on the right side. For number 3 I honestly have no idea I have never seen or done that equation in my life. For number 4 all you have to do is count up then how many left or right that goes to the line crossing a place where a point could be. For example you rise 3 and go over two it would be 3/2. Though that isn't the answer I hope this helps. Also I don't know number 8 either I am sorry but I also hope this helped a little bit.

Winter Wonderland buys items at wholesale, then marks them up to set a retail price. They buy snow globes for $9.20 and mark them up by 95%. What is the retail price or selling price of the snow globes?
Answer:
$17.94
Step-by-step explanation:
Step one:
given
the cost price of snow globes = $9.20
mark up percent= 95%
Required:
the retail selling price
Step two:
let us find 95% of $9.20
=95/100*9.20
=0.95*9.20
=$8.74
Hence the retail selling price is = 9.20+8.74
=$17.94
