Answer:
The markup percentage of the IPhone 7 is $218.18%.
Step-by-step explanation:
The IPhone 7 costs for Apple to make = $220
The cost in stores = $700
The difference between costing price and selling price = 700 -220 = $480
The markup percentage of the IPhone 7 = [tex]\frac{480}{220}[/tex] × 100
= $218.18
The markup percentage of the IPhone 7 is $218.18%.
The markup percentage of an iPhone 7 is calculated by finding the difference between the selling and cost price, dividing this by the cost price and then multiplying by 100. According to these steps, the markup percentage of the iPhone 7 is approximately 218%.
Explanation:The markup percentage indicates how much an item's price has increased from its original cost to make. It is calculated by finding the difference between the selling price and the cost to make, then dividing that by the cost to make, and then multiplying it by 100 to get the percentage.
To calculate the markup percentage of the iPhone 7:
Determine the difference between the selling price and the cost price. In this case, $700 (selling price) - $220 (cost price) = $480. Now divide the difference by the cost to make. $480 / $220 = 2.18. Finally, multiply by 100 to get the percentage. 2.18 * 100 = 218% (rounded to the nearest whole number).
Therefore, the markup percentage of the iPhone 7 is 218%.

A city has a population of 390,000 people. Suppose that each year the population grows by 8.75%. What will the population be after 12 years?
After 12 years, the population will be approximately 993,993 people.
The city's current population is 390,000 and it grows at a rate of 8.75% each year. To find the population after 12 years, we use the formula for exponential growth:
P(t) = P° × (1 + r)t
Where:
P(t) is the future populationP° is the initial populationr is the annual growth rate (expressed as a decimal)t is the number of yearsFirst, convert the growth rate to decimal form:
8.75% = 0.0875
Next, apply the exponential growth formula:
P(12) = 390,000 × [tex](1 + 0.0875)^{12}[/tex]
P(12) = 390,000 × [tex]( 0.08750)^{2}[/tex]
Using a calculator, we get:
P(12) = 390,000 × 2.5487
P(12) = 993,993

Answer:
0
Step-by-step explanation:
0 times anything is zero
ANSWER
x=-1.2 or x=1.6
EXPLANATION
The given equation is:
[tex] 5{x}^{2} - 2x - 10 = 0[/tex] Group and combine the constant terms:
[tex]5{x}^{2} - 2x = 10 [/tex]
Divide through by 5
[tex]{x}^{2} - \frac{2}{5} x = 2[/tex]
Add the square of the coefficient of x to both sides:
[tex]{x}^{2} - \frac{2}{5} x + \frac{1}{25} = 2 + \frac{1}{25} [/tex]
The left hand side is now a perfect square
[tex]( {x - \frac{1}{5} })^{2} = \frac{51}{25} [/tex]
Take square root:
[tex]{x - \frac{1}{5} }=\pm \sqrt{\frac{51}{25}} [/tex]
[tex]{x = \frac{1}{5} }\pm \frac{ \sqrt{51} }{5}[/tex]
[tex]{x = \frac{1}{5} } - \frac{ \sqrt{51} }{5} \: or \: \: {x = \frac{1}{5} } + \frac{ \sqrt{51} }{5}[/tex]

Question 2 options: 2(3x + 5 ) = 6x + 10
Answer:
Infinitely many solutions / All real numbers
Step-by-step explanation:
2(3x+5)=6x+10
Then, Distribute
6x+10=6x+10
Therefore, it is infinitely many solutions / all real numbers
For this case we must solve the following equation:
[tex]2 (3x + 5) = 6x + 10[/tex]
We apply distributive property to the left side of the equation:
[tex]6x + 10 = 6x + 10[/tex]
It is observed that we have an identity, that is, the terms on the right side are equal to the terms on the left side of the equation. Then, the equation has infinite solutions

Answer:
112.5 square units
Step-by-step explanation:
Area = 1/2bh
where b = 15 and h = 15 (you can look at the graph)

b₁, b₂ - bases
h - height
Substitute:
[tex]A_t=\dfrac{15+7}{2}\cdot5=\dfrac{22}{2}\cdot5=(11)(5)=55\ ft^2[/tex]
The formula of an area of a rectangle:

In Galveston, Texas there is a beautiful attraction called the Rainforest Pyramid which contains man plants and a variety of rainforest animals. The builders needed to calculate the volume of the squar pyramid to plan the climate control system. The length of the base is approximately 69.6 yards and the height is 33 yards. Which of the following is the closest estimate of the volume?
Answer:
53,286 yards
Step-by-step explanation:
69.6x69.6x33/3
The volume of the square pyramid is [tex]53,286[/tex] yards.
What is volume of the square pyramid?
The volume of a square pyramid is one-third of the product of the area of the base and the height of the pyramid.
[tex]V=\frac{1}{3} b^{2} h[/tex]
From the given,
The length of the base [tex]b[/tex] is [tex]$69.6\,\text{yards}$[/tex].
Height [tex]h[/tex] is, [tex]$33\,\text{yards}$[/tex].
We have to find [tex]V[/tex].
So,
[tex]$V=\frac{1}{3}{{\left( 69.6 \right)}^{2}}\cdot 33$[/tex]
[tex]$\therefore V=53286$[/tex]
Hence, the volume of the square pyramid is [tex]53,286[/tex] yards.

The areas of the square and the rectangle are equal.
What is the value of x?
Answer:
x=12
Step-by-step explanation:
Area of the square
A = x^2
Area of the rectangle
A = (2x-8) (x-3)
Foil
A = 2x^2 -6x -8x +24
= 2x^2 -14x+24
The areas are equal
x^2 = 2x^2 -14x+24
Subtract x^2 from each side
x^2 - x^2 = 2x^2-x^2 -14x+24
0 = x^2 -14x -24
Factor
0 = (x-12) (x-2)
Using the xero product property
x-12= 0 x-2 =0
x=12 x=2
But looking at the rectangle
x-3 is a side length
2-3 is negative so x cannot equal 2
x=12
