Job. The Company Gives Tenisha
A Raise, Now She earns $634 Per week.
How much Is Tenisha's Rais Per Hour?
Answer:
15.85

if you take and divide 634 by the 40 hours she works you get 15.85 also doing 550/40 gives you 13.75 to find the difference if you need it subtract 15.85-13.75= 2.1
Write the amount in standard scientific notation. 6E 5 petabytes
The scientific notation it can be written as 6 x [tex]10^5[/tex] petabytes.
What is Scientific notation?A given number, equation, or expression is written in a format known as a scientific notation, which adheres to a set of principles. Large numbers like 8.6 billion are difficult to write in their numerical form since they are not only unclear but also time-consuming, and there is a potential that we may write a few zeros more or less. So, we utilise scientific notation to clearly describe extremely large or extremely small integers.
Given:
6E 5 petabytes
Now, we have to write the above number in scientific notation.
Now, the E generally represents the exponents raise to some power.
6E 5 petabytes
= 6 x [tex]10^5[/tex] petabytes
Hence, in scientific notation it can be written as 6 x [tex]10^5[/tex] petabytes.

a certain forest covers an area of . suppose that each year this area decreases by . what will the area be after years? use the calculator provided and round your answer to the nearest square kilometer.
The area after 15 years is 517.40km²
What is an area?It is the quantity that expresses the content of the region on the plane or on a curved surface. Area is the size of the surface that can be calculated. It is the amount of space occupied by a two-dimensional figure. It is the quantity that measures the unit of squares. We get the area of the rectangle by multiplying length and width. The area of the figure is counted by the area of unit squares. It determines the area of the number of common shapes, including rectangle, trapezoid, circle, sector, ellipse etc.
y = A(1 - r)t
where,
A = initial area
r = rate
y = 1600(1 - 0.0725)
y = 1600[tex](0.9275)^{t}[/tex]
here we put t=15, then we get
y=1600[tex](0.9275)^{15}[/tex]
y=517.40 km²

The area of the parallelogram ABCD is 15 square units and is calculated using the distance formula and parallelogram area formula.
As per the question statement, coordinates of points A, B, C, D and E are given as follow:
A(-2,3), B(4,0), C(-3, 1), D(-5, 2) and E(-3, 1).
The parallelogram's area is the product of its base and height.
Base can be calculated using distance formula in points A and E
AE = √[(-3+2)^2 + (1-3)^2]
AE = √[(-1)^2 + (-2)^2]
AE = √[1+4]
AE = √5 units
Height can be calculated using the distance formula in points A and B
AB = √[(4+2)^2 + (0-3)^2]
AB = √[(6)^2 + (-3)^2]
AB = √[36 + 9]
AB = √45 units
Hence area of parallelogram = AB * AE
Area = √45*√5
Area = √225
Area = 15 sq units.
Hence, The area of the parallelogram ABCD is 15 square units and is calculated using the distance formula and parallelogram area formula.

The triangular based pyramid ABCD is shown
The base ABC is a right-angled triangle and the pyramid has a volume of 72cm^3
D is directly above A
AB=AC
AD=2 x AB
The length AB is labelled x
calculate the lenth x
Considering the volume of the pyramid, the length x is given as follows:
x = 6 cm.
What is the volume of a pyramid?The volume of a pyramid is given by the multiplication of one third of the base area Ab and the height h, as follows:
V = 1/3 x Ab x h.
In the context of this problem, the base is a right triangle with two equal sides x, hence the base area is:
Ab = 0.5(x)(x) = 0.5x².
The height is given by segment AD, hence:
AD = 2AB = 2x.
The volume is of 72 cm³, hence we can solve for the length x as follows:
V = 1/3 x Ab x h.
72 = 1/3(0.5x²)(2x)
x³ = 72 x 3
x³ = 216
x = cubic root of 216
x = 6.
Hence the missing side length is of x = 6 cm.

y=.78x+11.21
The equation of the least squares regression line for the data set is: A. y = .81x + 12.25
What is a regression line?A regression line simply refers to a statistical line that best describes the behavior of a data set. This ultimately implies that, a regression line refers to a line which best fits a set of data.
In this scenario, x₁ would be plotted on the x-axis of the scatter plot while y₁ would be plotted on the y-axis of the scatter plot.
By critically observing the scatter plot (see attachment) which models the data in the given table, we can reasonably and logically deduce that the equation for the line of best fit is given by:
y = 0.81x + 12.25

A frequency table categorizes the data into different groups based on frequency.
The characteristics of a frequency table in statistics are:
(A) Data is tabulated in a frequency table to show how frequently each score occurs.
(B) A frequency table can be used to study the data and its behavior.
(C) Based on frequency, a frequency table divides the data into various groups.
A frequency distribution is a list or table that displays the frequency of different outcomes in a sample. It can also be a graph.

Which graph best represents -2y =4x - 8 ? ASAP like RIGHT NEOW
The equation - 2y = 4x - 8 in slope intercept is y = - 2x + 4.
Consider the function,
- 2y = 4x - 8
The equation of a line in slope intercept form is y = mx + b where m is the slope and b is the y-intercept.
So,
- 2y = 4x - 8
y = - 2x + 4
Now,
When x = 0
y = - 2(0) + 4 = 4
When x = 1,
y = - 2(1) + 4 = 2
When x = 2,
y = - 2(2) + 4 = 0
When x = - 1,
y = - 2( - 1 ) + 4 = 6
When x = - 2,
y = - 2( - 2 ) + 4 = 8
When x = 3,
y = - 2( 3 ) + 4 = - 2
So, the point on the graph are ( 0, 4 ), ( 1, 2 ), ( 2, 0 ), ( 3, - 2), ( - 1, 6 ), ( - 2, 8 ).
