39. The occupations of postsecondary teachers, registered nurses,
and medical assistants are among the ten with the largest
growth from 2000 to 2012. (See the Chapter 2 opener.) The
number of postsecondary teacher jobs will grow 173 thou-
sand more than twice the number of medical assistant jobs.
The number of registered nurse jobs will grow 22 thousand
less than three times the number of medical assistant jobs.
If the total growth of these three jobs is predicted to be 1441
thousand, find the predicted growth of each job.
Answers
Answer:
Postsecondary teacher jobs = 431 thousandMedical assistant jobs = 258 thousandNurse jobs = 752 thousandStep-by-step explanation:
Given
Postsecondary teacher jobs = tMedical assistant jobs = mNurse jobs = nThe number of postsecondary teacher jobs will grow 173 thou-
sand more than twice the number of medical assistant jobs.
t= m + 173The number of registered nurse jobs will grow 22 thousand
less than three times the number of medical assistant jobs.
n= 3m - 22If the total growth of these three jobs is predicted to be 1441
thousand, find the predicted growth of each job.
t + m + n = 1441Substituting t and n in the last equation and solving for m:
m + 173 + m + 3m - 22 = 14415m + 151 = 14415m = 1441 - 1515m = 1290m = 1290/5m = 258 thousandFinding the rest
t = m + 173 = 258 + 173 = 431 thousandn = 3m - 22 = 3*258 - 22 = 752 thousand-1.4(-5+7g)=? simplify the expression

What is a mathematical expression?A mathematical expression is a sentence that has at least two variables or integers and one mathematical action. In mathematics, it is possible to multiply, divide, add, or subtract. The construction of an expression is as follows: Expression, number, and mathematical operator.
It is given that the expression is,-1.4(-5+7g
We have to simplify the expression.
Suppose the simplified value of the expression is x,
x= -1.4(-5+7g)
x= -1.4(-5)-1.4(7g)
x=7-9.8g

C) 4
D) 10
Answers
Answer:
x = 10
Step-by-step explanation:
[tex]3 - \frac{3}{4}x = \frac{1}{4}x - 7[/tex]
Start by subtracting 3 to both sides
[tex]-\frac{3}{4}x = \frac{1}{4}x-10[/tex]
Subtract 1/4x from both sides ( -3/4 - 1/4 ) = - 1
[tex]-x = -10[/tex]
Divide both sides by a negativ 1 to get rid of the negative
∴ [tex]x = 10[/tex]

Answer:
The Answer would be OD) Dividing both sides of Equation A by-3 gives x + 7 = -8.
Step-by-step explanation:
Simplify by dividing both sides by negative 3 so -3(x+7)/-3 would be x+7 and 24/-3 would be -8,
Thus, OD) is the answer.
The statement that explains this is true would be OD) Dividing both sides of Equation A by-3 gives x + 7 = -8.
It is given that Mai says x is a number that makes Equation A true and also a number that makes Equation B true.
• Equation A: -3 (x + 7) = 24
• Equation B: x + 7 = -8
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Simplify the Equation A by dividing both sides by negative 3;
so -3(x+7)/-3 would be;

At (-2,0) gradient is -4 ; At (2,0) gradient is 4
Step-by-step explanation:
For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).
y = x^2 - 4
y' = 2x
The function y = x^2 - 4 cross the x-axis when:
y = x^2 - 4
0 = x^2 - 4
4 = x^2
2 +/- = x
Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).
The gradient at these points are as follows:
y' = 2(-2) = -4
y' = 2(2) = 4

scores on the act college entrance exam follow a bell-shaped distribution with mean 18 and standard deviation 6. Wayne's standardized score on the ACT was -0.5. what was Wayne's actual ACT score?
Answers
Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15
The sum of 7 consecutive odd integers is 217. What is the smallest of the integers?
Answers
Answer:

Step-by-step explanation:
n+(n+2)+(n+4)+(n+6)+(n+8)+(n+10)+(n+12)=217
7n+42=217
7n=175
n=25
25+27+29+31+33+35+37=217
Answer:
25
Step-by-step explanation:
Let the smallest odd integer be n.
The integers are: n, n + 2, n + 4, n + 6, n + 8, n + 10, n + 12
Their sum is 217.
n + n + 2 + n + 4 + n + 6 + n + 8 + n + 10 + n + 12 = 217
7n + 42 = 217
7n = 175
n = 25

what is 4/5-1/6 with work shown

the denominators need to be the same so if we multiply the first fraction by 6 and the second by 5, our new equation is
24/30 - 5/30
24-5=19
19/30 is your answer
Answer & Step-by-step explanation:
[tex]\frac{4}{5}-\frac{1}{6}[/tex]
When you need to subtract fractions, the denominators (bottom) need to be the same. For this, you have to multiply both fractions until the bottom numbers are the same:
Find the lowest common multiple of the denominators:
[tex]5,10,15,20,25,30\\6,12,18,24,30[/tex]
The LCM of 5 and 6 is 30. Now you have to multiply the top and bottom of the fractions until you get a denominator of 30*:
[tex]\frac{4(6)}{5(6)}=\frac{24}{30}\\\\\frac{1(5)}{6(5)}=\frac{5}{30}[/tex]
So,
[tex]\frac{24}{30} -\frac{5}{30}[/tex]
When you subtract fractions, you only change the numerators (top). The denominator will stay the same:
[tex]\frac{24}{30} -\frac{5}{30}=\frac{19}{30}[/tex]
Since the fraction can't be further simplified, [tex]\frac{4}{5}-\frac{1}{6}=\frac{19}{30}[/tex]
:Done
*When you are finding the same denominators, you need to multiply a single fraction's numerator and denominator by the same number. The two different fractions don't need to be multiplied by the same number:
[tex]\frac{x(a)}{y(a)}-\frac{w(b)}{z(b)}[/tex]

the range of the function that would be used to determine how
far Katie can travel.
Answers
Answer: 175, 210, 245
Step-by-step explanation:
The distance covered by the Katires car after 5, 6, and 7 hours will be 175 ,210, and 245 miles.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.
Distance = speed × time
Given,
Speed = 35 hours.
Distance covered in 5 hours ⇒
35 × 5 = 175 miles.
Distance covered in 6 hours ⇒
35 × 6 = 210 miles
Distance covered in 7 hours ⇒
35 × 7 = 245 miles.
Hence, the distance covered by the Katires car after 5, 6, and 7 hours will be 175,210, and 245 miles.
