lines AB and BC are perpendicular. the dashed rays bisect angles ABD and CBD. explain why the measure of angle EBF is 45 degrees.
Angle EBF is 45 degrees because angle ABC is 90 degrees and line D divides each side into two equal parts.
How to determine angles?Given that lines AB and BC are parallel. Angles ABD and CBD are bisected by the dashed rays. Angle EBF is measured at 45 degrees because angle ABC is 90 degrees, line D divides each side into two equal parts, and half of 90 degrees is 45 degrees.
As a result, the angle EBF is 45 degrees because angle ABC is 90 degrees and line D divides each side into two equal parts, and half of 90 degrees is 45 degrees.

Step-by-step explanation:
The expression 5x − 4 > 2x + 3 looks like an equation but with the equals sign replaced by an arrowhead. It is an example of an inequality. This denotes that the part on the left, 5x − 4, is greater than the part on the right, 2x + 3.
Chad bought a box of donut hole that contain 60% glazed and the ret powdered ugar. The box ha 12 powdered ugar donut hole. How many glazed donut hole are in the box Chad bought?
The box has 18 glazed donut hole that Chad bought.
The percentage of glazed donut holes = 60%
The percentage of powdered sugar donut hole = (100 - 60) % = 40%
Let us consider the total number of donut hole in the box bought by Chad to be 'x'
Number of powdered sugar donut hole = 12
Hence, we can say that the number of powdered sugar donut hole in the box Chad bought is:
(40% of x) = 12
Therefore, x = (12 x 100) / 40 = 30
Since the total number of donut hole in the box = 30
The number of glazed donut hole = 30 - 12 = 18
Thus, the box that Chad bought had 18 glazed donut hole.

How do I solve (3.4) (6.7) using standard algorithm?
To solve the equation (3.4)(6.7) using the standard algorithm, first multiply 3.4 and 6.7. Then, the result is 22.78.
How to solve for the standard algorithm?The standard algorithm for multiplication is a step-by-step process that involves breaking down the numbers being multiplied into simpler parts, and then multiplying those parts together.
First, you would need to multiply the ones place of the first number (4) by the ones place of the second number (7), which would give you 28.
Next, you would need to multiply the ones place of the first number (4) by the tens place of the second number (6), which would give you 24.
Then, you would add the two products from steps 1 and 2 to get the result: 28 + 24 = 52.
Alternatively, you can use the distributive property of multiplication to simplify the problem.
(3.4)(6.7) = 3.46 + 3.40.7 = 22.8

Periodical Express is a newspaper printing company. They printed 450 copies of The Informer in just 15 seconds! They next need to print 300 copies of the Sport Report.
If they print at the same rate, how many seconds will it take to print the Sport Report?
Answer: To find out how many seconds it will take to print 300 copies of the Sport Report, we can use the formula:
time = (number of copies) / (rate of printing)
We know that the rate of printing for The Informer is 450 copies in 15 seconds. To find the rate of printing per second, we can divide the number of copies by the time in seconds:
rate of printing = 450 / 15 = 30 copies per second
So to find out how long it will take to print 300 copies of the Sport Report, we can use this rate of printing and plug it into the time formula:
time = (number of copies) / (rate of printing)
time = 300 / 30
time = 10 seconds
Therefore, it will take 10 seconds to print 300 copies of the Sport Report at the same rate as The Informer.

The slope is 2 using the slope-intercept form. As the slope of the line in slope-intercept form is the coefficient of x, the slope of the line is -2.
what is slope ?The slope of a line governs its steepness. Using mathematics, the gradient is expressed as "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical (rise) to the horizontal (run) change in distance between any two sites. Every time the equation for a straight line is written as y = mx + b, the slope-intercept representation of the equation is utilized. At the location of the y-intercept, the line has a slope of m, b, and c. (0, b). As an example, the y-intercept of the equation y = 3x - 7 has a value of 3. (0, 7).

y = 0.25*85.
What is percentage?
A number or ratio expressed as a fraction of 100 is known as a percentage in mathematics. Though the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent sign, "%," is frequently used to indicate it. An amount that is a percentage is dimensionless and has no assigned measurement.
Given:
The current box holds 85 ounces, 25% less rice.
We have to find the equation which is use to find the original amount of ounces of rice in a box, when the current box holds 85 ounces, 25% less rice.
Let, y be the original amount of ounces of rice in a box.
The current box holds 85 ounces.
The 25% less than 85 ounces are 85*0.25.
So, the equation becomes y = 0.25*85.
Hence, the equation which is use to find the original amount of ounces of rice in a box, when the current box holds 85 ounces, 25% less rice is
y = 0.25*85.

YES, This is an observational study.
The variables in this study are:
Media usage: categorical (explanatory variable)
Tiredness: quantitative (response variable)
This is an observational study. The researchers are observing and measuring the relationship between media usage and tiredness, but they are not manipulating or controlling any variables. They are collecting data by randomly selecting homes to visit and interviewing the adult member of the household whose birthday was nearest.
An observational study draws conclusions from a sample of a population in disciplines like epidemiology, social sciences, psychology, and statistics when the independent variable is not under the researcher's control due to ethical considerations or practical limitations. One typical observational study examines how a therapy may affect its participants, but the researcher has no control over which group the subjects are assigned to—the treated group or the control group. Unlike experiments like randomized controlled trials, when each subject is arbitrarily assigned to either a treated group or a control group, this does not happen. Observational studies naturally create challenges for inferential analysis because they lack an assignment mechanism.

Andrew is going to invest in an account paying an interest rate of 2.2% compounded quarterly. How much would Andrew need to invest, to the nearest hundred dollars, for the value of the account to reach $93,000 in 19 years?
Andrew would need to invest $61,300 for the account to reach $93,000.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
The equation to find final amount in compound interest is,
A = P (1 + r/n)^(n t)
Here A is the final amount, P is the initial amount, r is the rate of interest, n is the number of times compounding is done in a year, t is the time in years.
Given, A = $93,000
t = 19 years
r = 2.2% = 0.022
n = 4 (since compounding is quarterly)
93,000 = P [1 + (0.022/4)]^(4×19)
93,000 = P [1.0055]^(76)
93,000 = P (1.517)
P = 61,297.8516
To the nearest hundred dollars, P = $61,300
Hence the principal amount Andrew need to invest is $61,300.

Which point is the reflection of (- 3 2 over the y-axis?
The reflection of (-3, 2) over the y-axis is (-3, -2).
The reflection of a point (x, y) over the y-axis is (x, -y).
Therefore, the reflection of (-3, 2) over the y-axis is (-3, -2).
To calculate the reflection of (-3, 2) over the y-axis, we first use the formula (x, -y).
In this case, x = -3 and y = 2, so the reflection of (-3, 2) over the y-axis is (-3, -2).
We can also calculate the reflection of (-3, 2) over the y-axis using the distance formula.
The distance formula is d = √(x2-x1)2 + (y2-y1)2
In this case, x1 = -3, x2 = 0, y1 = 2, and y2 = 0.
Therefore, the distance d = √(02-(-3)2 + (02-2)2 = √(9 + 4) = √13
The reflection of (-3, 2) over the y-axis is (-3, -2). This can be verified using the distance formula.
d = √(x2-x1)2 + (y2-y1)2 = √(-3-0)2 + (-2-0)2 = √(9+4) = √13
The distance d is equal to the distance between (-3, 2) and (-3, -2). Hence, the reflection of (-3, 2) over the y-axis is (-3, -2).
