What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
The first 3-digit number divisible by 10 is 100, and the last 3-digit number divisible by 10 is 990.
The total number of such digits are,
= (990 - 10)/10 + 1.
= 980/10 + 1.
= 98 + 1.

Which definition states the measure of the sum of two angles is 90 *?
A. Def. of Complementary Angles
B. Def. of Congruent Angles
C. Def. of a Right-Angle
D. Def. of Supplementary Angles
A. Def. of Complementary Angles states the measure of the sum of two angles is 90°.
Complementary angles are two angles whose measures add up to 90 degrees. The definition states that if two angles are complementary, their measures will sum up to 90 degrees. The concept of complementary angles is important in trigonometry, where the complementary angles are used in the relationship between the sine, cosine, and tangent of an angle.
For example, if angle A is complementary to angle B, then we can write:
Angle A + Angle B = 90 degrees
It is important to note that complementary angles do not have to be adjacent or next to each other, but they must always add up to 90 degrees when measured in degrees.
Therefore, option A. Def. of Complementary Angles is the correct answer.

Step-by-step explanation:
For every hour that Jill worked,she made $10. Write an equation to model how much money she can make
jill makes $10 for every hour. so she makes 10x amount of money, where x stands for the number of hours.
For every hour that Jill worked, she made $10. So, the amount of mony that jill can make can be written in the form of a linear equation. the standard equation for linear model is
y = mx + b
in this case, x shows the input, y shows the output, m shows the amount earned per hour and b would be the fixed amount she ears, which will be 0 in this case.
therefore, the amount of money she earns will be
y = 10x

How would you graph y =- 2?
The graph is a horizontal line where all values for y are -2.
Now, According to the question:
What is called graph?
A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things.
Generally, graphs show a function, for example,
y = x −3. In that case, one would draw a graph by substituting an x value into the equation and connecting the points.
In this case, however, there are no x values in the equation. Therefore, regardless of the number on the x-axis, the y value will remain the same (−2). Therefore, the line will be a horizontal line with a slope of zero and a y-intercept of −2.

(3x + 15)° + (20x - 10)° + 60° = 180° {supplementary angles}
23x + 65° = 180°
x = (180° - 65)/23 {make x the subject}
x = 5

m∠ABC = 2(33) + 14° = 80°
m∠DBE = m∠CBG = (5x + 5)° {vertical angles}
(5x + 5)° + (x + 48)° + 55° = 180° {supplementary angles}

The correct statement is "only a and c are correct" so option g is the answer.
The statement that is true in a normal distribution is "approximately 70% of the values are within one standard deviation from the mean" (a), and "2.1% of the values are between -2 and -3 standard deviations from the mean" (c).
These statements are true because of the properties of a normal distribution, also known as a Gaussian distribution or bell curve. In a normal distribution, the majority of values cluster around the mean, with fewer and fewer values as you move further away from the mean.
The statement "twenty-seven percent of the values are between one and two standard deviations from the mean" (b) is not true, as the correct percentage is approximately 27.7% (68-95-99.7 rule).
The statement "0.1% of the values are 3 or higher standard deviations from the mean" (d) is also not true, as the correct percentage is approximately 0.3%.

The given expressions y =- 3+7x and y= − 3 − 7x are compared with the general form of slope y=mx+c. And the y-intercept of both is found to be -3.
A line's slope, often known as its gradient, is a numerical value that represents the line's steepness and direction. This slope provides the ratio of the rise in y when x rises by a specific amount. Therefore, this may be calculated using the basic formula y=mx+c, where c stands for the y-intercept and m for the slope.
Given the expressions are y = -3+7x and y= -3-7x. Compare these two expressions one by one with the general form of the slope. By comparing the first expression we get, the slope as 7 and the y-intercept as -3. Similarly, comparing the second expression we get, the slope is -7 and the y-intercept is -3.

How to Find the Simplest Form of a Fraction?If a fraction's top and bottom are whole numbers that are coprime to one another, it is said to be in its simplest form.It's easy to figure out how to simplify any fraction. By reducing the fraction's numerator and denominator by the greatest common factor that splits them both in half, we can simplify the numerator and denominator. The denominator and numerator should both remain whole numbers after division. Reducing fractions is another name for this fractional arithmetic procedure.Because the common component "c" is subtracted from both the numerator and the denominator, if the fraction is, for instance, ac/bc, then the simplified form of ac/bc will be a/b.ac/bc = a/b
Example :

What are the roots of 3x² 5x 2 0?
The roots of the quadratic equation 3x² + 5x - 2 = 0 are the two values of x that make the equation true. In this case, they are x = -2 and x = 0.
Step 1: Move all terms with an x to one side of the equation and all terms without an x to the other side:
3x² + 5x - 2 = 0
3x² + 5x = 2
Step 2: Divide both sides of the equation by the coefficient of the x² term (3):
(3x² + 5x)/3 = 2/3
x² + (5/3)x = 2/3
Step 3: Use the quadratic formula to calculate the roots of the equation:
x = [-b ± √(b² - 4ac)]/2a
x = [-(5/3) ± √((5/3)² - 4(1)(2/3))]/2(1)
x = [-(5/3) ± √(25/9 - 8/3)]/2
x = [-(5/3) ± √(7/9)]/2
Step 4: Calculate the values of x that make the equation true:
x = [-(5/3) + √(7/9)]/2
x = [-(5/3) - √(7/9)]/2
x = [-2]
x = [0]

The number of child tickets sold on Saturday is 5.
We know that at the city museum, the child admission is $5.20 and adult admission is $9.10. We also know that on Saturday 162 tickets were sold for a total sales of $1491.60.
We can use this information to find the number of child tickets sold on Saturday. We can set up an equation with the total sales and the price of the tickets.
Let x be the number of child tickets sold.
x(5.2) + (162-x)(9.10) = 1491.60
The equation represents the total sales by the number of child tickets sold multiplied by the price of child admission, and the number of adult tickets sold multiplied by the price of adult admission.
We can solve for x by isolating it and substituting the given values:
x(5.2) + (162-x)(9.10) = 1491.60
x*5.2 + (162-x)*9.10 = 1491.60
5.2x + 1472.20 - 9.10x = 1491.60

A decorator creates a scale drawing of a bedroom with a scale of 3 inches =5 feet. If the actual bedroom measures 24 feet long, how many inches long should the bedroom be in the scale drawing?
The bedroom should be 14.4 inches long in the scale drawing.
What is the proportion?
A proportion is an equation in which two ratios are set equal to each other.
If the scale of the drawing is 3 inches = 5 feet, that means that for every 3 inches on the drawing, it represents 5 feet in reality. To find how many inches the bedroom should be in the scale drawing, you can use the proportion:
(inches in scale drawing) / (feet in reality) = 3 inches / 5 feet
We know that the length of the actual bedroom is 24 feet. To find the length of the bedroom in the scale drawing, we can substitute 24 feet for the (feet in reality) in the proportion and solve for the (inches in scale drawing):
(inches in scale drawing) / 24 feet = 3 inches / 5 feet
Cross-multiplying gives:
(inches in scale drawing) = (24 feet)(3 inches / 5 feet) = 14.4 inches
