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

A souvenir shop sells two sizes of American flags. Small flags cost $3.50 and large flags cost $6.50. On a recent day, 155 flags were sold and $683.50 was collected. How many flags of each size were sold that day?
Answer:
Small flags = 108
large flags= 47
Step-by-step explanation:
Step one:
given
let the number of small lag be x
and big flags be y
so
3.5x+6.5y= 683.5----------1
x+y=155------------------------2
Step two:
from eqn 2 x= 155-y
put x= 155-y in eqn 1
3.5(155-y)+6.5y= 683.5
542.5-3.5y+6.5y=683.5
collect like terms
3y=141
divide by 3
y= 141/3
y=47
Step three:
put y= 47 in eqn 2
x+47=155
x= 155-47
x=108

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.

How long will it take to get $250 in interest if $2500 in invested at a 7% interest rate?
Answer:
If it is an annual percentage rate: 8.4 months
Step-by-step explanation:
2500 x .07 = 175
175 / 250 = .7 / 12months = 8.4 months
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 At the end of the first month, he has withdrawn 1m amount of money and ends up with $1800.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.

Which TWO expressions are equivalent to (x - y) 2/3 - 3/4 (y-x)
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.

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

Which values complete the table?
-3. ?
1. ?
0. ?
4. ?
- 3. ?
(Table)
a. 6, -2, -3, 13
b. -12, -2, -3, 13
C.-9, -1, -3,5
d. -4,0,-1,3
Answer:
C.-9, -1, -3,5
Step-by-step explanation:
Given
y = 2x - 3 ---- [missing equation]
Required
Complete the table
To do this, we simply substitute the values of x in the given equation.
When x = -3
y = 2 * -3 - 3
y = -6 - 3
y = -9
When x = 1
y = 2 * 1 - 3
y = 2 - 3
y = -1
When x = 0
y = 2 * 0 - 3
y = 0 - 3
y = -3
When x = 4
x = 2 * 4 - 3
y = 8 - 3
y = 5
Hence, the missing gap can be filled with: C.-9, -1, -3,5
