Answer:

c=9

Step-by-step explanation:

Let's solve your equation step by step:

1. [tex]1.5c-6+6=7.5+6[/tex]

1.5 [tex]1.5c=13.5[/tex]

2.[tex]\frac{1.5c}{1.5c}=\frac{13.5}{1.5c}[/tex]

3. C=9

1.5(9)-6=7.5

13.5-6=7.5

The y-intercept for the line, 2x + 5y = -6, is: 1.2.

Given:

2x + 5y = -6

Rewrite in slope-intercept form

5y = -2x - 6

y = -2/5x - 6/5

"b" = -6/5 = 1.2

Therefore, the y-intercept for the line, 2x + 5y = -6, is: 1.2.

No, she isn't

Step-by-step explanation:

(-2)² is basically -2 x -2, which we know is 4.

-2² is slightly different. In this case, you don't consider it as the square of -2, but you do the square ignoring the negative sign, and then add it at the end.

So think about it like this,

We do 2² first, and then add the minus, so it becomes -4 instead of positive 4. Does that make sense?

Answer: Incorrect

Step-by-step explanation:

Rule :

[tex](-10)^2=| -10|^2 =100 \\\\ -10^2=-(10)^2=-|10|^2=100[/tex]

Then :

[tex]\rm -2^2=-|2|^2=-4 \\\\ (-2)^2= |-2|^2=4 \\\\ Then : \\\\ -2^2 =(-2)^2 \\\\ -4 \neq 4[/tex]

Answer:

3/8g + 2 = 5  

Subtract the number 2 from both sides of the equation.

3/8g = 3

Now divide 3/8 from both sides of the equation.

3/8 divided by 3/8 equals 0.  3 divided by 3/8 equals 8.

The final answer is:

g = 8

------------------------------------------------------------------------------------------

Check your answer:

3/8g + 2 = 5

Substitute 8 into the spot where the variable g was.

3/8 X 8 + 2 = 5

So our answer x = 8 is true.

Answer:

Option B,14.6 cm and D,20.3 cm

Step-by-step explanation:

Let a and b represent the lengths of the two known sides such that a≥b. Let c represent the length of the unknown side, the length of c must fall within  

a−b<c<a+b

11.9-9.1<c<11.9+9.1

2.8<21

By elimination,

Option B and D remain, i.e 14.6 cm & 20.3 cm

The solutions to the system of equations are (5,2), no solutions, (7,3), (2,7), no solutions and (3,5) respectively.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

(1) Systems of equations

2x + y = 12

x = 9 − 2y

See the graph given below the solution is the point (5,2).

(2) Systems of equations

x + 2y = 9

2x + 4y = 20

See the graph given below the solution is the point has no solution the two lines are parallel.

(3) Systems of equations

x + 3y = 16

2x − y = 11

See the graph given below the solution is the point (7,3).

(4) Systems of equations

y = 11 − 2x

4x − 3y = -13

See the graph given below the solution is the point (2,7).

(5) Systems of equations

y = 10 + x

-3x + 3y = 30

See the graph given below the system has no solutions.

(6) systems of equations

2x + y = 11

x − 2y = -7

See the graph given below the solution is the point (3,5).

Therefore, the solutions to the system of equations are given below in the figure.

A scale on a map is used to compare one length with another length.

The two locations on the map are 3 centimeters apart.

From the question, a map represents every 18 kilometers with 1 centimeter. Hence:

18 kilometers = 1 centimeter

54 kilometers = ?

Cross Multiply

54 kilometers x 1 centimeter / 18 kilometers

= 3 centimeters.

Therefore, the two locations on the map are 3 centimeters apart.

[tex]7.01568 * 10^6=7015680[/tex] minutes

There are:

60 minutes in an hour

24 hours in a day (60 * 24 = 1440 minutes)

30 days in a mouth (1440 * 30 = 43,200 minutes)

360 days in a year (1440* 365 = 525,600 minutes)

To find out how many years old she is we must divide the number of minutes old she is by the number of minutes in a year.

7015680 / 525,600 = 13 years with a remainder of 182,880 minutes

To find out how many months old she is we must divide the remaining minutes by the number of minutes in a month.

182,880 / 43,200  = 4 months with a remainder of 10,080 minutes

To find out how many days old she is we must divide the remaining minutes by the number of minutes in a day.

10,080 / 1440 = 7 days

Answer: Mia is 13 years, 4 months and 7 days old

Answer:

X-ray technicians, also referred to as radiologic technologists, would need math skills to be able to use accurate calculations when mixing chemicals used in x-ray imaging processes. In addition to this, the critical and logical thinking abilities practiced in the study of mathematics are useful in the day to day job, especially because working with imaging technology and machines to get detailed images for physicians to view is crucial to patient care and treatment.

Education for an associate's degree in radiologic technology is going to be focused heavily on STEM related courses such as anatomy, radiation safety, imaging procedures, and pathology. For this reason, it is recommended that high school students planning on pursuing this educational path take plenty of classes in math, science, and technology.

Radiologic technology job opportunities are expected to increase by 9 percent between 2018 and 2028 according to the Bureau of Labor and Statistics. This is greater than the 5 percent average increase projected for all other jobs, which means radiological technology is a career with a strong and stable outlook.
