Answer:
62
Step-by-step explanation:
This question is easy.
I don't know how to explain the formula as I am afraid it would be confusing, so I would just write the solution and you can analyse it.
105 - 19 = 86 (Find out how much the college would have without the more)
86 ÷ 2 = 43 (Find out male and female teachers in a seperate way without more)
43 + 19 = 62 (Female teachers)
Sorry if my explaination wasn't so accurate, I tried my best to make sure you understand it.
The proportion of the teachers that are female is 62 teachers.
Let the number of female teachers be F.Let the number of male teachers be M.Given the following data:
Total number of teachers = 105 teachersTo calculate what proportion of the teachers are female:
Translating the word problem into an algebraic expression, we have;
[tex]F + M = 105[/tex] .....equation 1
[tex]F = M + 19[/tex] .....equation 2
[tex]M = F - 19[/tex] .....equation 3
Substituting eqn 3 into eqn 1, we have:
[tex]F+F-19 =105\\\\2F -19=105\\\\2F = 105+19\\\\2F= 124\\\\F = \frac{124}{2}[/tex]
F = 62 teachers

Write a rule for the nth term of the arithmetic sequence described below.
A5 =
91 and a20 =
1
an=
A25=
Answer:
an = 115 + (n - 1) (-6)
a25 = - 29
Step-by-step explanation:
We use the definition for the nth term of an arithmetic sequence:
an = a1 + (n - 1) d
a5 = 91 = a1 + (5 - 1) d
91 = a1 + 4 d
a20 = 1 = a1 + (20 - 1) d = a1 + 19 d
1 = a1 + 19 d
now we subtract term by term one expression from the other
90 = 4 d - 19 d
90 = - 15 d
divide both sides by -15 to isolate d
d = 90 / (-15) = -6
Now we can calculate what a1 is using for example:
1 = a1 + 19 d
1 = a1 - 114
add 114 to both sides:
115 = a1
Then our general expression for the sequence is:
an = 115 + (n - 1) (-6)
We can now use it to calculate the value of a25:
a25 = 115 + (24) * (-6) = -29

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?
Answer:
$63
Step-by-step explanation:
I believe you meant Richard worked for 7 hours and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.
7 hours x 9 dollars/hour = $63Therefore, Richard earned $63 for his 7-hour work.
Additional Information
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
10 hours x 9 dollars/hour = $90Evaluate f(x) = 3x - 2 + 1 for f(-2) and f(1)

I need some help to to solve each proportion - I want to be able to explain to my son how to do this properly. The math problem is- 4 over 6 = blank over 21 ?
Answer
The missing value is -14
Step-by-step explanation:
First you make a ratio or proportion: -4/6=x/21
Then you cross multiply
-4x21 which is -84 then 6 times x which is 6x then the equation becomes 6x=-84
from 6x you divide which becomes x=-84/6 which is -14

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."

Step-by-step explanation:
An angle is equal to the sum of the angles into which it is divided.
∠MLK = ∠MLP + ∠PLK
164° = (x +31)° +(x +147)°

Find the lengths of the diagonals of rectangle WXYZ
WY = 6x - 7
XZ = 3x + 2
The length of each diagonal is units
Answer:
√(45x²-72x+53)
Step-by-step explanation:
When you insert diagonals, two rightangled triangles are formed.
To find the length of the diagonals, we put the rectangles into pythagorus's theorem:
a²=b²+c²
a²=(6x-7)²+(3x+2)²
a²=36x²-84x+49 + 9x²+12x+4
a²=45x²-72x+53
a=√(45x²-72x+53)
Distribute first, then combine like terms:
