Triangles ABC And JKL Are Similar.What Is The MF 5G 48H 66J 132

Answers

Answer 1
Determine if the two triangles are Isosceles:

Because triangles ABC and JKL are similar, sides BC and KL must be proportional. We see that triangle JKL has two congruent sides lengths opposite of the base angles, making triangle JKL Isosceles. Therefore, triangle ABC must also have two corresponding, proportional side lengths that are also congruent to each other and opposite the base angles, making triangle ABC Isosceles, too. So, side BC must also be 5, since the two sides opposite of the base angles must be congruent in an Isosceles Triangle.

Properties of Isosceles Triangles:

When the two sides opposite of the base angles are congruent in a triangle, the triangle is Isosceles, and those base angles must also be congruent.

Solving for angle measures:

We can now apply the Triangle Sum Theorem: all three interior angles in a triangle must sum up to 180.° This will allow us to solve for the measure of angle B.Let’s create an equation:

48+x+x=180

The variable “x” is used to denote an unknown angle value. Notice that there are two “x” in the equation. This is because we know these two base angles will be congruent, thus they can use the same variable.

Simplify:

48+2x=180

Solve for x:

Subtract 48 from both sides:

2x=180-48

2x=132

Divide both sides by 2:

x=132/2

x=66

Therefore, the two base angles measure 66.° One of these base angles is angle B, and because the base angles are congruent, m∠B=66.°

A college newspaper interviews a psychologist about student ratings of the teaching of faculty members. The psychologist says that the evidence indicates that the correlation between the research productivity and teaching rating of faculty members is close to zero. The paper reports this as Professor McDaniel said that good researchers tend to be poor teachers, and vice versa. Which statement in plain language (i.e. without the word correlation) correctly explains the psychologist's meaning?
A)There is little connection between research productivity and teaching rating.
B) While bad researchers tend to be good teachers, there is no similar relationship between good researchers and bad teachers.
C) While good researchers tend to be bad teachers, there is no similar relationship between bad researchers and good teachers.
D) Good researchers tend to be bad teachers and bad researchers tend to be good teachers.

Answers

Answer:

The correct option is A.

Step-by-step explanation:

As the psychologist states that there is no correlation found between teaching ratings and research productivity of the same faculty member, meaning that there is no significant relationship between the two. The paper's report states quite the opposite, that there is an inverse correlation. The statement that explains what the psychologist says correctly is A. There is little connection between teaching rating and research productivity.

area of a circle is 254.34 cm2. What is the diameter of the circle, use 3.14.​

Answers

The area of a circle is:

Area = PI x r^2 ( r is the radius which is half the diameter)

Using the information in the problem:

254.34 = 3.14 x r^2

Divide both sides by 3.14:

81 = r^2

Take the square root of both sides:

r = 9

The diameter = 2r = 2(9) = 18 cm

diameter is 18 cm in length

Of 20 students, 9 are girls

Answers

Girls: 45%
Boys : 55%

Answer:

45% and 55%

Step-by-step explanation:

Total student = 20

No of Girls = 9

No of boys = Total student - No of Girls

                  =20-9

                  =11

Percentage of Girls = (No of Girls / Total student) * 100

                           = (9/20)*100

                           = 45 %

Percentage of Boys = (No of Boys/ Total student) * 100

The dock foreman gets to work each day at 5:30 A.M. He goes to lunch at 11:01 A.M. and gets back to work at noon. He goes home for the day at 3:20 P.M.

How many hours does the foreman work in a 5−day work week?

Answers

Answer:

The foreman works approximately 44 hours in a 5−day workweek.

Step-by-step explanation:

In one day the dock foreman works the following hours:

[tex]t = (11 h + 01 min*\frac{1 h}{60 min}) - (5 h + 30 min*\frac{1 h}{60 min}) + 15 h + 20 min*\frac{1 h}{60 min} - 12 h = 8.85 h = 8 h + 51 min[/tex]

Now, in 1 5-day work week the man works:

[tex]T = 5*t = 5*8.85 h = 44.25 h = 44 h + 15 min[/tex]

Therefore, the foreman works approximately 44 hours in a 5−day workweek.

The value of a house wa shilling 600,000 in 2005.It increased by 25% in 2006 and 10% in 2007 but dropped by 15% in 2007 find its value in 2008​

Answers

Given:

The value of a house is 600,000 in 2005.

It increased by 25% in 2006 and 10% in 2007 but dropped by 15% in 2007.

To find:

The value of the house in 2008.

Solution:

We have,

Value of house in 2005 = 600,000

It increased by 25% in 2006.

Value of house in 2006 = [tex]600,000+\dfrac{25}{100}600,000[/tex]

                                        = [tex]600,000+150,000[/tex]

                                        = [tex]750,000[/tex]

It increased by 10% in 2007

Value of house in 2007 = [tex]750,000+\dfrac{10}{100}750,000[/tex]

                                        = [tex]750,000+75,000[/tex]

                                        = [tex]825,000[/tex]

But it dropped by 15% in 2007.

Value of house in 2008 = [tex]825,000-\dfrac{15}{100}825,000[/tex]

                                        = [tex]825,000-123,750[/tex]

                                        = [tex]701,250[/tex]

Therefore, the value of the house in 2008 is 701,250.

and example of vertical angles would be 6 and 3, they basically form an x, another example is 5 and 2, 1 and 4, etc

an examples of angles that would qualify as neither would be 1 and 3, they are not next to one another, thus they are not adjacent, and they do not form an x so they are not vertical, another example would be 5 and 3
