Answer:
Alice Gleason invested 16000 each for 9% and 11% rate respectively
Step-by-step explanation:
Let
x = portion invested for 9%
y = portion invested for 11%
Then
x + y =32000 eqn(1)
0.09x + 0.11y =3200 eqn(2)
solving eqn(1) and eqn(2) simultaneously
multiply eqn(2) by 100 gives and eqn(1) by 9
9x +11y =320000 eqn(3)
9x + 9y = 288000 eqn(4)
subtract eqn(4) from eqn(3) to obtain y
2y = 32000
y=16000
substitute y=16000 into eqn(1) to obtain x
x=32000-16000
x=16000

Answer:
40 part-time male students were in the survey.
Step-by-step explanation:
Given:
Total number of students in the Phoenix high school = 100
Number of female student = 40
Number of male student who went to Phoenix Full time = 20 students
Total number of full time students = 50 students
To Find:
Number of part time male students in the survey = ?
Solution:
we know that the total number of students = 100
Now total number of male students = total number of students - total number of female student
Now total number of male students = 100 - 40 = 60 students
Now among these 60 students, 20 males went to Phoenix
Full time
So the remaining male students = 60-20 =40 students
Hence these 40 students are part-time male students
Answer:
y=1.4x+6.8
Step-by-step explanation:
(-2;4) (-7;-3)
4=-2k+b
-3=-7k+b
7=5k
k=1.4
-2.8+b=4
b=6.8
I already know k and b so I can write an equation.
y=1.4x+6.8
