Answer:
9.8E^-5 (or 9.8*10^-5)
Step-by-step explanation:
0.000098 converted to scientific notation is either 9.8E^-5 or 9.8*10^-5 as they are the same, just different ways of writing it. To get this, you just count the spaces away from the decimal point the number is.
ex.) 0.98 = 9.8E^-1 as it just has to move 1 decimal
980 = 9.8E^1 as it has to move 1 decimal to the positive side

The expression that is equivalent to the given expression is -2x/15 + 2. The correct option is the third option- negative two over fifteen times x plus two
Evaluating an ExpressionFrom the question, we are to determine the expression that is equivalent to the given expression
The given expression is
1/5(3x +10) - (11/15)x
Clear the parentheses by applying the distributive property
1/5(3x) + 1/5(10) - (11/15)x
3x/5 + 2 - 11x/15
Collect like terms
3x/5 - 11x/15 + 2
(9x - 11x)/15 + 2
-2x/15 + 2

Solve the system of equations 8x- 3y =9 4x -4y=-8
Answer:
x = 3, y = 5.
Step-by-step explanation:
8x - 3y = 9
4x - 4y = -8
multiply the second equation by 2:
8x - 8y = -16
Subtract this from the first equation:
5y = 25
y = 5.
Substitute for y in equation 2:
4x - 4(5) = -8
4x = -8 + 20 = 12

How can a graphical representation help you analyze data ?
Answer: It helps in analyzing large quantities, comparing two or more data, making predictions, and building a firm decision.
Step-by-step explanation To visualize the relationship between two numerical variables the most appropriate graph is a scatter plot. If there is a clear distinction between the independent (explanatory) and the dependent (response) variable, it is common to plot the independent variable on the x-axis and the dependent on the y-axis. The main use of a graphical representation of data is understanding and identifying the trends and patterns of the data.

Define fractions.A fraction is a percentage of a whole. This entire sentence could be referring to a single location or a collection of locations. The English word "fraction" derives from the Latin word "fractio," which means "to break."

The weight of the remaining sea shells Jonathan has is 1¾ kg.
What exactly are fractions?A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction describes the number of parts of a specific size, such as one-half, eight-fifths, or three-quarters. There are three major types of fractions in mathematics. Proper fractions, improper fractions, and mixed fractions are the three types. Fractions are terms that have a numerator and a denominator.So, the weight of the remaining sea shells: 4½ - 2¾
Now, solve the above fraction operation for the weight of remaining sea shells.
= 4½ - 2¾= 9/2 - 11/4= 18-11/4= 7/4kg= 1¾ kgTherefore, the weight of the remaining sea shells is 1¾ kg.

Step by Step Explanation:
First, find the answer of 9^(-3), which would be 0.00137174211. Then, convert that into fraction form. Which would be 137174211/100000000000. Then simplify, which in order to simplify a fraction, there must be: 1. A number that will divide evenly into both the numerator and denominatior so it can be reduced. No such number exists for 137174211 and 100000000000. or 2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number. 137174211 is not greater than 100000000000, also meaning, this fraction is in it's simplest form.

Wite an equation perpendicular to y=-2x-7 that passes through the point (4,3)
Answer:
y = 1/2 x + 1.
Step-by-step explanation:
A line perpendicular to a line with slope m will have a slope of -1/m.
The line y = -2x - 7 will have a slope of -1/ -2 = 1/2.
Using the point-slope form of a straight line
y - y1 = m(x - x1)
Here m = 1/2 and (x1, y1) = (4, 3).
So, y - 3 = 1/2(x - 4)
y = 1/2x - 2 + 3
y = 1/2 x + 1.

First, let us find the measurement of angle QPM as angle QPR and angle QPM are supplementary angles that is there sum will be 180° :
∠QPM + QPR = 180°
∠QPM + 115° = 180°
∠QPM = 180° - 115°
∠QPM = 65°

The points (0, 0) and (1, 3) fall on a particular line. What is its equation in slope-intercept
form?
Answer:
y = 3x
Step-by-step explanation:
Slope-intercept form of an equation is a shortcut, fill-in-the-blank form you can use to write the equation of a line.
Slope-intercept eq:
y = mx + b
You fill in slope where the m is. And you fill in the y-intercept for the b.
In your problem they gave you two points. You can calculate slope with two points. Subtract the y's, 3-0, put that on top of a fraction. And subtract x's, 1-0, put that on the bottom of the fraction. The slope, m, is 3/1, which is 3.
slope:
m = 3-0 / 1-0 = 3/1 =3
The y-intercept is actually given in your problem. The y-intercept is the point where the line crosses the y-axis. The y-intercept is the point where the x is 0. They gave you the point (0,0) that is the y-intercept. So b = 0.

One year, Kim pays 9260 income tax work out how much she earned that year
Answer: Kim made roughly 46,300 that year.
Step-by-step explanation:
We know that income tax = 9260
Step 1 is to find out which tax bracket Kim comes under.
The min. tax for those in the 20% bracket is 7,500. (20% * 37,500)
The min. salary for those in the 40% bracket is 45,000. (40% * 112,500)
As Kim pays 9260 in tax, we know that she falls under the 20% bracket. As such, we can conclude that :
20% * (Kim's Salary) = 9260
Kim's Salary = 9260/20%(or 0.2)
Kim's salary = 46,300

Firstly we will analyze the question statement to determine the best possible answer.
So, the statement tells us about a person named Natalie,, the owner of an App designed for teenagers. Currently, the New Mindfulness app has One thousand two hundred and sixty-two downloads. Natalie sets a target to take her App downloads to double every month.
We are expected here to provide her with the best possible exponential equation to make her achieve the set goal.
We can use two variables for our exponential equation:
y for the number of downloads.
And x for the months.
We can use any value (Whole numbers, decimals, or fractions) in our exponential equation.
Now while keeping in mind all the necessary details, we can make the exponential equation as below:
Y= 1262 (2 x b) ^ x
Where Y are the downloads
X= 1 month or 30 days
By putting the values:
Y=1262 (2) ^ 1 month
Y=2524 after one month
So, the total number of downloads will double using the above exponential equation.
The pictures below show a relationship between the number of downloads Y and the month X.

A relation between a collection of inputs and outputs is known as a function.
The order pairs can't be a function also,
f(x) = -√x → D: x ≥ 0

Which of the ordered pair sets defines a function?A relation is simply a collection of ordered pairs (x, y). In formal mathematics, a function is a relation in which x1= x2 if (x1,y) and (x2, y) are both in the relation. This simply states that two ordered pairs with the same x -value but different y -values cannot exist in a function.A function's range is the set of all its outputs. Example: Consider the function f: A B, where f(x) = 2x and A and B are both sets of natural numbers. In this case, A is the domain and B is the co-domain. The range is then the result of this function.If an x value has more than one y-value associated with it, as in the relation (4, 1), (4, 2), the x-value of 4 has y-values of 1 and 2, indicating that this set of ordered pairs is not a function. If each x-value has only one y-value, the relationship is a function.The order pairs can't be a function also,
