can someone explain?
Her weekly pay is $250
Her monthly pay is $1000
Her yearly pay is $12000
Her weekly take-home pay if she takes home 76% is $190
What is a unit rate?Unit rate is the ratio of two different units, with the denominator as 1.
We have,
1 hour = $12.50
1 week = 20 hours
The weekly pay:
= 20 hours
= 20 x 12.50
= $250
Monthly pay:
= 4 weeks
= 4 x 20 hours
= 80 hours
= 80 x 12.50
= $1000
Yearly pay:
= 12 months
= 12 x 4 weeks
= 48 weeks
= 48 x 20 hours
= 960 hours
= 960 x 12.50
= $12000
Weekly take-home pay:
= 76% of $250
= 76/100 x 250
= $190

Zendaya has $540 to spend at a bicycle store for some new gear
and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $269.88.
She buys 4 bicycle reflectors for $10.57 each and a pair of
bike gloves for $17.76.
She plans to spend some or all of the money she has left to
buy new biking outfits for $65.65 each.
Write and solve an inequality which can be used to determine
x, the number of outfits Zendaya can purchase while staying within her budget.
The inequality to determine the number of outfits Zendaya can purchase while staying within her budget is
269.88 + 4*10.57 + 17.76 + 65.65x ≤ 540
And the number of outfits Zendaya can buy is 3 .
According to the question we have been given that the
Total money Zendaya has = $540
Cost of new bicycle = $269.88
Cost of bicycle reflectors = $10.57
Cost of bike gloves = $17.76
Cost of biking outfits = $65.65
Let the number of outfits Zendaya purchases be x.
The inequality to determine the number of outfits Zendaya can purchase while staying within her budget is
269.88 + 4*10.57 + 17.76 + 65.65x ≤ 540
Now solving this inequality for x we get
269.88 + 42.28 + 17.76 + 65.65x = 540
329.92 + 65.65x = 540
65.65x = 210.08

Select one:
O a. Absolute difference: -492 people per square mile
Relative difference: -81.3%
O b. Absolute difference: 492 people per square mile
Relative difference: 435.4%
O c. Absolute difference: -492 people per square mile
Relative difference: -435.4%
O d. Absolute difference: -492 people per square mile
Relative difference: -8.1%
Answer: c
Step-by-step explanation:
The absolute difference is 492 people per square mile and Relative difference: 435.4%.
Thus, option (B) is correct.
To find the absolute difference between the two population densities, subtract the population density of country A from the population density of country B:
Absolute difference = Population density of country B - Population density of country A
= 605 people per square mile - 113 people per square mile
= 492 people per square mile
Now, the relative difference as a percentage, we use the formula:
Relative difference = (|Absolute difference| / Population density of country A) * 100
= (|492| / 113) * 100
= (492 / 113) * 100
= 4.35398230088 * 100
= 435.4%
Therefore, the absolute difference is 492 people per square mile
Relative difference: 435.4%
Thus, option (B) is correct.

[tex]d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex]
(x₁, y₁) = (1, 4) and (x₂, y₂) = (4, 0)
So distance is

Find all of the points of the form (x,-1) which are 3 units from the point (-6, 1).
(x, y) =
(smaller x-value)
(x, y) =
(larger x-value)
Answer:
The values of x are -6 + √5 and -6 - √5.
Step-by-step explanation:
It is given that we need to find all of the points of the form (x,-1) which are 3 units from the point (-6, 1).
Now, let us suppose that these points are in 2D coordinate system such as;
=> (x1, y1) = (-6, -1)
and let us suppose that the other point is;
=> (x2, y2) = (x, 1)
Further, the distance between both these points them is 3 units and we can write this as;
=> d = √(x1 - x2)² + (y1 - y2)²
=> 3 = √(-6 - x)² + (-1 - 1)²
After squaring both the sides;
=> 9 = 36 + x² + 12x + 4
=> 9 = x² + 12x + 40
On rearranging the equation;
=> x² + 12x + 31 = 0
Now, this is a quadratic equation of the form ax² + bx + c = 0 in which;
=> x = -b ± √(b² - 4ac) / 2a
After putting values in this for obtaining the value of x on comparing we get;
=> x = -12 ± √(12² - 4×31) / 2
=> x = -12 ± √(144 - 124) / 2
=> x = -12 ± √20 / 2
=> x = -12 ± 2√5 / 2
=> x = 2(-6 ± √5) / 2
=> x = -6 ± √5
Therefore, the values of x are -6 + √5 and -6 - √5.

Where, S is area of square with side x.
What is Area of square?
A square is a two dimension figure in which all the sides are equal. Since all the sides are equal, the area would be two times the side of a square.
Let a side of square is x feet.
Then, Area of a square (S) = x²
When, The side of the square is increased by 2 feet. Then area is increase by 12 sq. ft.
Then, Side of a square = (x + 2)

Find the missing side. Round to the nearest tenth.
By using trigonometric relations, we can see that the hypotenuse of the right triangle measures 30.8 units.
How to find the missing side on the right triangle?
Here we will need to use trigonometric relations. We want to find the value of x, which is the hypotenuse of the right triangle.
We know the measure of one angle, and the adjacent cathetus to said angle, the measures are:
angle = 65°
Cathetus = 13 units.
Now we can sue the trigonometric relation:
cos(a) = (adjacent cathetus)/(hypotenuse)
Replacing what we know, we can rewrite that as:
cos(65°) = 13/x
Now we just need to solve the equation for x, we will get:
x = 13/cos(65°) = 30.8 units.

What is translation?
A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.
Given that,
The translation is 1 units left and 5 units up.
The coordinates of the given figure are R(-3, -3), S(-3, -1), T(2, 0) and
U(1, -5).
Now, If the translation is 1 units left and 5 units up, then the coordinates become (x - 1, y + 5).
Hence, Coordinates for the image of the graph are;
R' = (-4 - 1, 2 + 5) = (-5, 7)
S' = (-3 - 1, -1 + 5) = (-4, 4)
T' = (2 - 1, 0 + 5) = (1, 5)
U' = (1 - 1, -5 + 5) = (0, 0)
Hence, The coordinates are R'(-4, 2), S'(-4, 4), T'(1, 5) and U' (0, 0).
Therefore, The figure with the coordinates R'(-4, 2), S'(-4, 4), T'(1, 5) and

8 x 8^4x-3 = 512 x 8^x
The solution using indices for the given equation is (x = 5/3).
What is meant by indices?The small floating quantity that makes it appear after an amount or letter is known as an index or power. Indexes is the plural of index. Indices represent the number of times a quantity or letter has indeed been multiplied on its own.Indexes are also referred to as powers or exponents. It indicates how many times a provided number must be multiplied.The multiplication of x is equal to the base x raised to a power of p.For the given expression in question;
8 × 8⁴ˣ⁻³ = 512 × 8ˣ
By the property of indices, if the base is equal; then the powers are added with sign.
8⁴ˣ⁻³⁺¹ = 512 × 8ˣ
As, we know that 512 is the cube of 8.
8⁴ˣ⁻² = 8³ × 8ˣ
Apply the power law on right side;
8⁴ˣ⁻² = 8³⁺ˣ
As, the base on both side is equal, then the exponents are also equal.
Thus,
4x - 2 = 3 + x
Bring variables and constants on different sides.
4x - x = 3 + 2
