Justin is buying a cell phone that had a wholesale price of
$495. The cell phone was marked up 25%.
What is the selling price of the cell phone?
Answer:
$371.25
Step-by-step explanation:
If you want to take away 25%, you would need to find out how much 75% of the current price is. IF you think about it, 75% of the $495 is 25% of 100% of it taken away.
So
0.75 x 495 = 371.25

The value of x for the given triangle will be 111°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The sum of all angles inside a triangle is 180°
So,
47° + x° + 22° = 180°
x = 180° - 69° = 111°
Hence "The value of x for the given triangle will be 111°".

what is the equation of a like that goes through the point 5,-2 and has a slope of. 6/5
Answer:
y= 6/5x -8
Step-by-step explanation:
The slope-intercept form (basically the form for the equation of a line)
y=mx+b
m is the slope
x is the value you want to plug in, or the x term in a point (x, y)
we know so far,
y=6/5x + b
so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope
-2 = 6/5(5) + b
6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6
so
-2 = 6 + b
subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)
-8 = b

Why does the government charge high taxes on gasoline?
Answer:
Every time you top off your vehicle at the pump, you're paying federal and state gas taxes that are included in the price of every gallon of gasoline. The federal tax, at 18.4 cents per gallon, is meant to help the federal government pay to build and fix things like highways and bridges.
Step-by-step explanation:
Mark me brainliest
Answer: These taxes are meant to do two things — raise money to pay for infrastructure and reflect some of the environmental costs of driving. Unlike most taxes, gas taxes are charged as a flat charge per liter, rather than as a percentage of the pump price.

in a salad with vegetables containing 50 calories dressing is added at 100 calories per ounce. The total number of calories can be represented by the equation f(x) = 100x +50. What is the reasonable range for the situation?
Answer:
Step-by-step explanation:
To get the reasonable range of the situation, we will find the minimum value and maximum value of the calories that can be dressed.
The minimum occur at when x = 0
f(0) = 100(0) +50.
f(0) = 50
Hence the minimum value of the calorie is 50.
The maximum value occur at f'(x)
f'(x) = 100
Hence the maximum value of the calorie is 100
Hence, the reasonable range for the situation is 50 ≤ x ≤ 100

Which of the following answers is the best description for the deer population with the greatest growth rate: A.The blue line shows a deer population that grew with an exponential growth rate. In the first year the population increased by only one deer, but between years seven and eight the population grew by two deer, showing that the growth rate continuously doubles. B.The blue line shows a deer population that grew with a linear growth rate, because the graph shows that the population increased by approximately one deer per year. C. The red line shows a linear growth rate, because an approximate straight line estimates a growth rate of five deer per year. D. The red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing
Answer: D) the red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing.

Find the gradient of the straight line joining A(-4, -1) to B(4, 2)
Answer:
The slope of the line is [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
Given parameters:
A(-4, -1) to B(4, 2)
Unknown:
The slope of the line joining the two points
Solution:
To find the slope of the line; we use the expression below:
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]
x₁ = -4
y₁ = -1
x₂ = 4
y₂ = 2
Input the parameters and solve;
Slope = [tex]\frac{2 -(-1)}{4-(-4)}[/tex]
Slope = [tex]\frac{3}{8}[/tex]
The slope of the line is [tex]\frac{3}{8}[/tex]

z is 122
Did I mess it up? Can I get checked?
Answer:
You are correct!
Step-by-step explanation:
Hi!
You are right! If y is in the same spot as 58 degrees, then y is 58 degrees as well! Same goes for x. If z is 122 degrees, then x must be 122 degrees! Great job figuring this one out!

The product of two positive numbers is always greater than either number
The product of two positive numbers is always greater than either number the statement is false.
What are numbers?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.
Given that the product of two positive numbers is always greater than either number.
To understand this let's take an example take two numbers and multiply them.
2 x 5 = 10
Then take 2 and 0.5 and multiply them.
2 x 0.5 = 1
Here the result of the product is 1 which is less than 2. Therefore, if the product of two positive numbers is always greater than either number the statement is false.

Answer: (1) -3/4 (2) 7 (3) y = (-3/4)x + 7 (4) 1/2
Step-by-step explanation:
1) COUNT the number of spaces from one point to the other point.
from (0, 7) to (4, 4) is: down 3 and right 4 → m = -3/4
2) the y-intercept is where the line crosses the y-axis (when x = 0).
The line crosses the y-axis at (0, 7) → b = 7
3) Slope-Intercept form is y = mx + b
m = -3/4 and b = 7 → y = (-3/4)x + 7
4) COUNT the number of spaces from one point to the other point.
from (-2, -4) to (2, -2) is: up 2 and right 4 → m = 2/4 = 1/2 when simplified
