A friend purchases items from a website and resells them on her own website. She typically marks up her merchandise 40%. If she purchased an item for 15$, what price should she set for the item?
Answers
Answer:
$21
Step-by-step explanation:
Step one:
given
she purchased an item for $15
marks up her merchandise 40%.
let us find 40% of $15
and add the answer to the initial price of the item
Step two:
40/100*15
=0.4*15
=$6
Hence the price should she set for the item is
=15+6
=$21
Sarah and her friends ordered a pizza. Sarah ate 5 1 of the pizza. Her friend John ate 20% and her friend Jules ate half of the pizza. How much pizza is left over?
Answers
Given:
Sarah ate [tex]\dfrac{1}{5}[/tex] of the pizza.
Her friend John ate 20%.
Her friend Jules ate half of the pizza.
To find:
The remaining part of the pizza.
Solution:
We have,
Sarah ate = [tex]\dfrac{1}{5}[/tex] of the pizza.
John ate = [tex]20\%[/tex] of the pizza.
= [tex]\dfrac{20}{100}[/tex] of the pizza.
= [tex]\dfrac{1}{5}[/tex] of the pizza.
Jules ate = [tex]\dfrac{1}{2}[/tex] of the pizza.
Total part of a pizza they ate = [tex]\dfrac{1}{5}+\dfrac{1}{5}+\dfrac{1}{2}[/tex]
= [tex]\dfrac{2+2+5}{10}[/tex]
= [tex]\dfrac{9}{10}[/tex] of the pizza.
Now, the remaining pizza is
Remaining pizza = 1 - Total part of a pizza they ate
= [tex]1-\dfrac{9}{10}[/tex] of the pizza.
= [tex]\dfrac{10-9}{10}[/tex] of the pizza.
= [tex]\dfrac{1}{10}[/tex] of the pizza.
Therefore, the remaining pizza is [tex]\dfrac{1}{10}[/tex] of the pizza.

My equation equals 180. With the 3 variables missing
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, and it needs additional information before it can be answered.
However, a possible question could be that we generate an equation that has 3 variables and equals 180.
A possible question is:
The sum of three consecutive numbers is 180. What is the highest number?
And the solution is as follows:
Let the three numbers (in order of smallest to greatest) be x, y and z
So, the sum is:
[tex]x + y + z = 180[/tex]
Since the numbers are consecutive, then the following relationship exist:
[tex]y = x + 1[/tex]
[tex]x = x + 2[/tex]
Substitute x + 1 for y and x + 2 for z in [tex]x + y + z = 180[/tex]
[tex]x + x + 1 + x + 2 = 180[/tex]
Collect Like Terms
[tex]x + x + x = 180 - 3[/tex]
[tex]3x = 177[/tex]
Solve for x
[tex]x = 177/3[/tex]
[tex]x = 59[/tex]
The value of the highest being is:
[tex]z = x + 2[/tex]
[tex]z = 59 + 2[/tex]
[tex]z = 61[/tex]
You can generate as many equation as possible

In the worlds coolest freezer sodium gas was cool to temperature of 78.5 below zero and then called 194.65 more what was the new temperature of the sodium gas
Answers
Answer:
[tex]-273.15^{\circ}\text{C}[/tex]
Step-by-step explanation:
[tex]T_i[/tex] = Initial temperature of sodium gas = [tex]-78.5^{\circ}\text{C}[/tex]
[tex]\Delta T[/tex] = Change in temperature of sodium gas = [tex]-194.65^{\circ}\text{C}[/tex]
[tex]T_f[/tex] = Final temperature of sodium gas
Change in temperature of gas is given by
[tex]\Delta T=T_f-T_i\\\Rightarrow T_f=\Delta T+T_i\\\Rightarrow T_f=-194.65+(-78.5)\\\Rightarrow \Delta T=-273.15^{\circ}\text{C}[/tex]
The new temperature of sodium gas is [tex]-273.15^{\circ}\text{C}[/tex].

If J is the centroid of cde, de=52, fc=15, he=14, find each missing measure
Answers
Answer:
[tex]DG = 26[/tex]
[tex]GE = 26[/tex]
[tex]DF = 15[/tex]
[tex]CH = 14[/tex]
[tex]CE = 28[/tex]
Step-by-step explanation:
The figure has been attached, to complement the question.
[tex]DE = 52[/tex]
[tex]FC = 15[/tex]
[tex]HE = 14[/tex]
Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:
[tex]DF = FC[/tex]
[tex]CH = HE[/tex]
[tex]DG = GE[/tex]
Solving (a): DG
If [tex]DG = GE[/tex], then
[tex]DE = DG + GE[/tex]
[tex]DE = DG + DG[/tex]
[tex]DE = 2DG[/tex]
Make DG the subject
[tex]DG = \frac{1}{2}DE[/tex]
Substitute 52 for DE
[tex]DG = \frac{1}{2} * 52[/tex]
[tex]DG = 26[/tex]
Solving (b): GE
If [tex]DG = GE[/tex], then
[tex]GE = DG[/tex]
[tex]GE = 26[/tex]
Solving (c): DF
[tex]DF = FC[/tex]
So:
[tex]DF = 15[/tex]
Solving (d): CH
[tex]CH = HE[/tex]
[tex]CH = 14[/tex]
Solving (e): CE
If [tex]CH = HE[/tex], then
[tex]CE = CH + HE[/tex]
[tex]CE = 14 + 14[/tex]
[tex]CE = 28[/tex]

y = 2x + 2
4x - y = -6
Answers
Answer:
x = - 2, y = - 2
Step-by-step explanation:
Given the 2 equations
y = 2x + 2 → (1)
4x - y = - 6 → (2)
Substitute y = 2x + 2 into (2)
4x - (2x + 2) = - 6 ← distribute and simplify left side
4x - 2x - 2 = - 6
2x - 2 = - 6 ( add 2 to both sides )
2x = - 4 ( divide both sides by 2 )
x = - 2
Substitute x = - 2 into (1) and evaluate for y
y = 2(- 2) + 2 = - 4 + 2 = - 2
solution is x = - 2, y = - 2

- 7x – 4y = -44
7x - 3y = 16
Answers
Answer:
{x,y} = {5,8}
Step-by-step explanation:
[1] 7x-3y+5=16
[2] 4y=3x+17
[1] 7x - 3y = 11
[2] -3x + 4y = 17
// Solve equation [2] for the variable y
[2] 4y = 3x + 17
[2] y = 3x/4 + 17/4
// Plug this in for variable y in equation [1]
[1] 7x - 3•(3x/4+17/4) = 11
[1] 19x/4 = 95/4
[1] 19x = 95
// Solve equation [1] for the variable x
[1] 19x = 95
[1] x = 5
// By now we know this much :
x = 5
y = 3x/4+17/4
// Use the x value to solve for y
y = (3/4)(5)+17/4 = 8

Write the explicit formula.
• Determine the 15th term of the sequence?
Answers
Açık formülü yazın.
• Dizinin 15. terimini belirleyin?
Answer:
see explanation
Step-by-step explanation:
The explicit formula for a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 200 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{100}{200}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]a_{n}[/tex] = 200 [tex](\frac{1}{2}) ^{n-1}[/tex] ← explicit formula
The 15 th term is then
a₁₅ = 200 × [tex](\frac{1}{2}) ^{14}[/tex]
= 200 × [tex]\frac{1}{16384}[/tex]
= [tex]\frac{200}{16384}[/tex] ← divide numerator/ denominator by 8
= [tex]\frac{25}{2048}[/tex]
You decide to market your own custom computer software. You must invest $3,255 for computer hardware, and spend $2.90 to buy and package each disk. If each program sells for $13.75, write a system of equations and determine how many disks you must sell to break even.
Answers
Answer:
13.75x = 3,255 + 2.90x
Step-by-step explanation:
Given that,
Amount invested on computer hardware = $3,255
Amount invested to buy and package each disk = $2.90
Selling price for each program = $13.75
We need to find the equation that is used to find how many disks you must sell to break even. Let there are n disks that you must sell.
ATQ,
$3,255 is a fixed amount. $2.90 and $13.75 depends on x.
So,
13.75x = 3,255 + 2.90x
We can solve the above equation to find the no. of disks.
13.75x - 2.90x = 3255
10.85x = 3255
x = 300
Hence, you must sell 300 disks to break even.

Costs of homes can be very different in different parts of the United States. a. A 450-square-foot apartment in New York City costs $540,000. What is the price per square foot? Explain or show your reasoning. b. A 2,100-square-foot home in Cheyenne, Wyoming, costs $110 per square foot. How much does this home cost? Explain or show your reasoning.
Answers
Answer:
The cost of homes per square foot differs in different part of the United states. The cost of homes per square foot is gotten by using the formula:
cost of homes per square foot = Cost of apartment / area of apartment
1) Cost of apartment = $540000, area of apartment = 450 ft²
cost of homes per square foot = Cost of apartment / area of apartment = $540000/ 450 ft² = $1200 / ft²
2) cost of homes per square foot = $110/ ft², area of apartment = 2100 ft²
cost of homes per square foot = Cost of apartment / area of apartment
$110 / ft² = Cost of apartment / 2100 ft²
Cost of apartment = $110 / ft² × 2100 ft² = $231000
