A jewelry store sells a necklace at $365 that was original purchased at $240, what is the markup? Round your answer to the nearest whole percent.
We are given a selling price of $365 and a purchase cost of $240, we are asked to find the markup. The formula for calculating the mark up is the following:
[tex]\text{markup}=\frac{sale\text{ price-cost}}{\cos t}[/tex]we have that the sale price is 365 and the cost is 240. Replacing in the formula:
[tex]\text{markup}=\frac{365-240}{240}[/tex]solving the operations we get:
[tex]\text{markup}=\frac{125}{240}=0.52[/tex]This can be expressed as a percentage like this:
[tex]\text{markup}=52\text{ percent}[/tex]the markup is 52%
what number do I need to add -5 to get -7
- 5 - 2 = - 7
The number that you need to add to - 5 to get - 7 is - 2
This can be ssen on the number line. If you are adding, you move towards the right but since we are adding a negative number, the - sign makes the plus sign to become - sign. So we would subtract by moving 2 points to the left of -5 and that gives - 7

prove that the sum of the lengths of the diagonals of a quadrilateral is less than the perimeter but greater than the half of the perimeter of this quadrilateral
Let us consider a quadrilateral ABCD (as shown in the figure below) such that AC and BD are the two diagonals of ABCD.
Now, in triangle ABC and triangle ADC, by using the properties of triangle inequality we have-
AB +BC > AC .... (1)
and AD + CD >AC .... (2)
adding equations (1) and (2) we get-
AB+ BC+CD+AD > 2AC .... (3)
Similarly for diagonal BD we get-
AB+BC+CD+AD > 2BD .... (4)
Adding equations (3) and (4) we get-
2(AB+BC+CD+AD) > 2(AC+BD)
⇒ (AB+BC+CD+AD) > AC+BD
here (AB+BC+CD+AD) = perimeter of quadrilateral.
Hence, we have proven that the sum of the length of the diagonals of a quadrilateral is less than the perimeter.
Now the 2 diagonals divide the quadrilateral into 4 quadrilaterals
Therefore, AO+OD > AD
OD+OC > CD
OC+OB > BC
and OA+OB > AB
Adding all these equations-
2(AC+BD)>AB+BC+CD+AD
⇒AC+BD > 1/2(AB+BC+CD+AD)
Hence, we've proven that the sum of the length of the diagonals is greater than the half of the perimeter of this quadrilateral.

Suppose you have an experiment where you toss a fair coin 3 time you didn't count the number of heads observe over those 3 tosses use this experiment to address each of the falling question round solution to 3 destiny places
a) In order to complete the table for the probability distribution for the variable X:
X = the number of heads observed when you flip a coin three times,
b) we create a list of all the possible outcomes. We use the notation: H = heads, T = tails.
The possible outcomes after tossing the coin three times are:
[tex]HHH,HHT,HTH,THH,TTT,TTH,THT,HTT[/tex]From the list above we see that we have 8 equiprobable events. Now, we classify the events according to the number of Heads included.

- Events with x = #H = 1: HTT, THT, TTH
- Events with x = #H = 2: HHT, HTH, THH
- Events with x = #H = 3: HHH
Using the data above we compute the probabilities for each x, we simply compute the quotient between the number of outcomes of each case by N = 8 (the total number of possible outcomes):

Three people travel by car to San Diego, a distance is 380 miles. Thetrip takes 6 hours. Daily cost for meals is $20 per person and gas costs$3.59 per gallon and their vehicle gets 15 mpg. Calculate the cost perperson for this trip to the nearest dollar.A) $85B) $70C) $50D) $90E) $105
Given:
• Distance = 380 miles
,• Time = 6 hours
,• Daily cost for meals = $20 per person
,• Cost of gas = $3.59 per gallon
,• Vehicle gets 15 miles per gallon.
Let's calculate the cost per person for this trip.
We have the following:
To find the total cost of gas they used for this trip, we have:
[tex]\frac{380}{15}*3.59=90.95[/tex]The total cost of gas for this trip is $90.95
The cost of gas per person will be:
[tex]\frac{90.95}{3}=\text{ \$30.32}[/tex]Cost of gas per person is $30.32
Therefore, the cost per person for this trip will be:
Cost per person = Cost of gas per person + Cost of meal per person
Cost per person = $30.32 + $20 = $50.32 ≈ $50
Therefore, the cost per person for this trip to the nearest dollar is $50

The slope of the line is 125.
The slope in the context represent the change in price with respect to the sizes of the houses.
The line won't pass through the point (5, 650)
How to find the slope of a line?The slope of a line is the change in y with respect to change in x.
Therefore,
slope = m = y₂ - y₁ / x₂ - x₁
using (0, 0)(2, 250)
m = 250 - 0 / 2 - 0
m = 250 / 2
Therefore,
m = 125
The slope simply implies the change in price with respect to the change in sizes of the houses.
Using the slope intercept equation we can know if the line passes through (5, 650).
Therefore,
y = 125x + 0
625 = 125(5)

Solve:
3x + 4y = 8
⇒ 3x -3x + 4y = 8 -3x ⊂ Subtract 3x from both side ⊃

A pizza parlor offers a choice of 12 different toppings. How many 2-topping pizzas are possible? (no double-orders of toppings are allowed)
==========================================================
Explanation:
There are 12 choices for the first topping and 11 for the next topping. The decrease is to account for the fact we cannot select a repeat topping.
That gives 12*11 = 132 permutations. If order of toppings mattered, then this would be our final answer.
However, the topping order doesn't matter. So we need to divide by 2 to correct for the double counting.
There are 132/2 = 66 combinations.
------------
Alternative Method:
n = 12 toppings are available and r = 2 selections are allowed
Order doesn't matter so we use the nCr combination formula
[tex]n C r = \frac{n!}{r!(n-r)!}\\\\12 C 2 = \frac{12!}{2!*(12-2)!}\\\\12 C 2 = \frac{12!}{2!*10!}\\\\12 C 2 = \frac{12*11*10!}{2!*10!}\\\\ 12 C 2 = \frac{12*11}{2!}\\\\ 12 C 2 = \frac{12*11}{2*1}\\\\ 12 C 2 = \frac{132}{2}\\\\ 12 C 2 = 66\\\\[/tex]
There are 66 combinations
Notice the 2nd to last step involves 132/2 which was mentioned in the previous section.

Kennedy's car used 16 gallons to travel 288 miles. How many miles can the car go for
each gallon of gas?
Answer:
18 miles
Step-by-step explanation:
The car needs 16 gallons to travel 288 miles. We can divide by 16, kind of like dividing on both sides of an equation, to get that with 1 gallon, the car can travel 288/16=18 miles.
for choose one you have to tell me what kind of angle it is.
Part 1
By angle addition property
m<4+m<5+m<1=180 degrees
m<4=39 degrees
m<5=45 degrees
substitute
39+45+m<1=180
m<1=180-39-45
m<1=96 degreesPart 2
we see that
m<4 and m<3 are alternate interior angles
and since lines, l and k are parallel, <4 and <3 are congruent
so
m<3=39 degreesPart 3
we see that <2 and <5 are alternate interior angles
and since lines, l and k are parallel, < 2 and <5 are congruent
so m<2=45 degrees
Part 4
therefore m<1+m<2+m<3=180 degrees
The relationship between <1, <2 and <3 is an example of the following rule
The sum of the interior angles measures of a triangle is 180 degrees
