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

HELP FAST PLEASE!!!!! Which of the following is an equation of the translation y = sin x, shifted π units up?
y = sin (x + π)
y = sin x + π
y = sin (x − π)
y = sin x − π

What is the area of the gray triangle shown?
Answer:
The area of the triangle is basically half the area of the square, so we only need to find the area of the square and divide it by 2:
S = (15 · 15)/2 = 112.5 (square units)
Answer:
112.5 square units
Step-by-step explanation:
Area = 1/2bh
where b = 15 and h = 15 (you can look at the graph)
So A = 1/2(15)(15) = 225/2 = 112.5 square units
Answer
112.5 square units

Step-by-step explanation:
The given points seem to match those of (half) a parabola that opens to the right. The parent function would be ...
x = y^2
or ...
y = √x . . . . . gives the upper half of the parabola only
It seems to have a vertical expansion by a factor of 3 and a translation of the vertex from (0, 0) to (-3, -2). The transformed function is then ...
y = 3√(x +3) -2
_____
We have transformed the parent function using ...
y = a·f(x-h) +k
where a is the vertical expansion factor, h is the horizontal translation, and k is the vertical translation.

A particular computer takes 78 nanoseconds to carry out seven sums and ten products. Another computer takes 55 nanoseconds to carry out 4 sums and eight products. How long does the computer take to carry out one sum? One product?
Answer:
The time that the computer take to carry out one sum is 4.63 nanoseconds and the time that the computer take to carry out one product is 4.56 nanoseconds
Step-by-step explanation:
Let
x----> the time that the computer take to carry out one sum
y----> the time that the computer take to carry out one product
we know that
7x+10y=78 ------> equation A
4x+8y=55 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (4.625,4.563)
see the attached figure
therefore
The time that the computer take to carry out one sum is 4.63 nanoseconds
The time that the computer take to carry out one product is 4.56 nanoseconds

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

The parent function is [tex]y=3^x[/tex]
The transformation applied to the parent function to obtain the given function is of the form,[tex]f(x+1)[/tex], which is a horizontal shift to the left by one unit.
To graph [tex]y=3^{x+1}[/tex] we shift the graph of [tex]y=3^x[/tex] to the left by one unit.
Estimate the square root to the nearest integer.
2. 39
A : 5
B: 8
C: 6
D: 7
Answer:
C
Step-by-step explanation:
The square root of 39 is ~6.25 so 6 is closest
Answer:
2
Step-by-step explanation:
Think: 2.39 is sandwiched between the perfect squares 1 and 4.
The difference between 1 and 4 is 3. From 1 to 2.39 is a step of 1.39; from 2.39 to 4 is a step of 1.61. Therefore, 2.39 is closer to 1 than to 4, and we estimate 2.39 to be 2 (to the nearest integer).

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.
