Answer:

D. none of these

Step-by-step explanation:

The image only shows two congruent angles/sides. In order for one of the given postulates to work, 3 congruent parts of the triangles must be applicable.

The line which is perpendicular to the line 4x + 3y = 21 is y = x + 1.

We know lines have various types of equations,

The general type is  Ax + By + c = 0, and the equation of a line in

The slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

An equation of a line is given which is 4x + 3y = 21 or 3y = - 4x + 21.

So, The line has a slope(m) = - 4.

∴ The line perpendicular to this line has a slope of (1/4) as perpendicular lines have slopes that are negative reciprocals of each other and it is passing through the points (4, 2).

∴ 2 = (1/4)(4) + b.

b = 1.

∴ y = x + 1 is the line.

Answer:

4

Step-by-step explanation:

Use slope intercept form: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{6-2}{2-1}[/tex] = [tex]\frac{4}{1}[/tex] = 4

Answer:

she can't finish reading the book in 10 days

Step-by-step explanation:

Given that:

Number of pages = 325

Number of pages read per day= 25

Using the linear relation:

y = mx + c

y = number of pages left

m = reading rate ; c = initial number of pages

y = - 25x + 325

Point slope relation :

y - y1 = m(x - x1)

m = slope

We can factorise the equation to the point slope form:

y - 325 = 25(0 - 10)

y - 325 = 0 - 250

y - 325 = - 250

y = - 250 + 325

y = 75

Hence, number of pages left after 10 days = 75, thus she can't finish reading the book in 10 days

Answer:

B: 2 2/3

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Funny, because i'm learning about this right now. The best way to solve this is to imagine it in real life. Imagine having 2/3 of a cup of sugar to make 1/4 of a cake. To make a whole cake, you would need to multiply 1/4 times 4, to get 1 sheet cake. You have to do the same thing with the cups of sugar: 2/3 times 4, which would get you 2 2/3 cups, which is B. Please correct me if I am wrong, everybody makes mistakes.

Answer:

623,000,000,000,000 > 8,912,000,000,000

Step-by-step explanation:

8.912·10^12

The exponent is 12, making it 10 to the power of 12. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 12 time(s):

8.912 -> 8,912,000,000,000

6.23·10^14

The exponent is 14, making it 10 to the power of 14. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 14 time(s):

6.23 -> 623,000,000,000,000

Answer:

Because we know for a fact that the line has a correct answer. Plus, if you choose a point on the line then it will not give you the visual side of which is correct and which is wrong.

Step-by-step explanation:

If you choose a point on the line then it will not give you the visual side of inequality. Therefore, choose the interval.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line. For a vertical line, larger solutions are to the right and smaller solutions are to the left.

Answer:

The maintenance electrician takes 287.555555566667 hours to to rewire all the motors

Step-by-step explanation:

1. Calculate all of the minutes for all the numbers.

It takes you 26.6666667 minutes to rewire 2/3 of a motor.

It takes you 160 minutes to rewire 4 motors.

It takes you 266.666667 to rewire 6 2/3 motors

It takes you 7,200 minutes to rewire 180 motors

It takes you 9,600 minutes to rewire 240 motors

2. Add all of the minutes together.

26.666667 + 160 + 266.666667 + 7,200 + 9,600 = 17253.333334

It takes you 17253.333334 minutes to rewire 431.333333 motors

Answer:

(a) 2.22

(b) 1.3986

(c) 1.183

Step-by-step explanation:

Let X denote the number of women who consider themselves fans of professional baseball.

The proportion of women who consider themselves fans of professional baseball is, p = 0.37.

A random sample of n = 6 women are selected and each was asked if she considers herself a fan of professional baseball.

Each woman's reply is independent of the others.

The random variable X thus follows a binomial distribution with parameters n = 6 and p = 0.37.

(a)

Compute the mean of the binomial distribution as follows:

[tex]\text{Mean}=np=6\times 0.37=2.22[/tex]

(b)

Compute the variance of the binomial distribution as follows:

[tex]\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986[/tex]

(c)

Compute the standard deviation of the binomial distribution as follows:

[tex]\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183[/tex]
