Answer:
D
Step-by-step explanation:
0.2x+5=8
0.2x=3
x=15
Therefore, the correct answer is choice D. Hope this helps!
Explanation: remember to isolate the variable, so first, subtract five from five and eight on both sides since subtraction is additions inverse operation. Now, the equation looks like 0.2x=3. Next, divide 0.2 by 0.2 and 3 so you can isolate x on the left side. 0.2 equals to 15, so x = 15.

what is the resultant displacement of 6m north 8m east and 10m north west?
Answers
The resultant displacement is approximately 13.071m north and 8m east.
To find the resultant displacement, we need to combine the given displacements in a vector-like manner.
Let's break down the displacements into their components and then add them up.
The first displacement is 6m north.
Since it is purely in the north direction, its components would be 6m in the north direction (along the y-axis) and 0m in the east direction (along the x-axis).
The second displacement is 8m east.
As it is purely in the east direction, its components would be 0m in the north direction and 8m in the east direction.
The third displacement is 10m northwest.
To find its components, we can split it into two perpendicular directions: north and west.
The northwest direction can be thought of as the combination of north and west, each with a magnitude of 10m.
Since they are perpendicular, we can use the Pythagorean theorem to find the components.
The north component would be 10m multiplied by the cosine of 45 degrees (45 degrees because northwest is halfway between north and west).
Similarly, the west component would be 10m multiplied by the sine of 45 degrees.
Calculating the components:
North component = 10m \(\times\) cos(45°) = 10m \(\times\) 0.7071 ≈ 7.071m
West component = 10m \(\times\) sin(45°) = 10m \(\times\) 0.7071 ≈ 7.071m
Now, let's add up the components:
North component: 6m (from the first displacement) + 7.071m (from the third displacement) = 13.071m north
East component: 8m (from the second displacement).

what is the equation of a line that passes through the points (2,5) and (4,3)
Answers
The equation of a line that passes through points (2,5) and (4,3) is
y = -x+7.
Finding the equation of a line:
First, we need to find out the slope for the given points.
(X1,Y1) = (2,5)
(X2,Y2) = (4,3)
formula for slope(m) = \(\frac{Y2 - Y1}{X2 - X1}\)
substitute the points in the above formula
\(\frac{3 - 5}{4 - 2}\) = \(\frac{-2}{2}\)
\(\frac{-2}{2}\) = -1
slope for the given points(m) = -1.
m = -1
The equation of a line is y-y1 = m(x-x1), where x and y are variables.
substituting the values in the above equation then :
y-5 = -1(x-2)
y-5 = -x+2
y+x = 2+5
x+y = 7
y = -x+7
Therefore, the equation of the line passing through the points (2,5) and (4,3) is y = -x+7

A construction company is building a retaining wall. It has a 12-inch piece of stone and then
bricks are stacked on top. Each brick measures 1.5 inches in height and the entire wall must
be at least 60 inches tall. How many rows of bricks will the retaining wall have?
Answers
The retaining wall will need to have at least 32 rows of bricks to reach a height of at least 60 inches, not counting the initial 12-inch piece of stone.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The wall needs to be at least 60 inches tall, and we already have a 12-inch piece of stone, so we need to stack enough rows of bricks to reach a height of:
60 inches - 12 inches = 48 inches
Each row of bricks adds 1.5 inches to the height
we can divide the remaining height of 48 inches by the height of each row:
48/1.5 = 32 rows
Therefore, the retaining wall will need to have at least 32 rows of bricks to reach a height of at least 60 inches, not counting the initial 12-inch piece of stone.

From the information given in the exercise, we build the confidence interval and solve this question. First, we have to find the point estimate for the population proportion, then using this point estimate, and sample size, we build the confidence interval. According to the built confidence interval, question c is answered.
Item a:
522 out of 1005 indicated that television is a luxury that they could do without, so:
\(\pi = \frac{522}{1005} = 0.5194\)
Thus, the point estimate for the population proportion of adults in the country who believe that televisions are a luxury they could do without is 0.5194.
Item b:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the z-score that has a p-value of .
For this problem, we have that:
\(n = 1005,\pi = 0.5194\)
95% confidence level
So \(\alpha = 0.05\), z is the value of Z that has a p-value of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).
The lower limit of this interval is:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5194 - 1.96\sqrt{\frac{0.5194*0.4806}{1005}} = 0.4885\)
The upper limit of this interval is:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5194 + 1.96\sqrt{\frac{0.5194*0.4806}{1005}} = 0.5503\)
Thus, the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.4885,0.5503). The interpretation is that:
We are 95% confident the proportion of adults in the country who believe that televisions are a luxury they could do without is between 0.4885 and 0.5503.
Item c:
It is possible, but unlikely that a supermajority of adults in the country believe that television is a luxury they could do without because the 95% confidence interval does not contain 60%.

The polynomial -8m²n - 7m²n can be factored using the common factor -m²n. The complete factored form of the polynomial is (-m²n) (8 + 7a).
To find the complete factored form of the polynomial -8m²n - 7m²n, we can factor out common terms from both the terms. The common factor in the terms -8m²n and -7m²n is -m²n. We can write the polynomial as:
-8m²n - 7m²n = (-m²n) (8 + 7a)
Therefore, the complete factored form of the polynomial -8m²n - 7m²n is (-m²n) (8 + 7a). This expression represents the original polynomial in a multiplied form. We can expand this expression using distributive law to verify that it is equivalent to the original polynomial.

find the absolute value of the following rational number
Answers
The absolute value of the Rational number -474/513 is 474/513.
To find the sum of the rational numbers -8/9 and -2/57, you need to have a common denominator. The least common multiple (LCM) of 9 and 57 is 513. So, you can rewrite the fractions with a common denominator:
-8/9 = (-8/9) * (57/57) = -456/513
-2/57 = (-2/57) * (9/9) = -18/513
Now, you can add the fractions:
-456/513 + (-18/513) = (-456 - 18)/513 = -474/513
To find the absolute value of the rational number -474/513, you simply ignore the negative sign and take the value as positive:
| -474/513 | = 474/513
Therefore, the absolute value of the rational number -474/513 is 474/513.
