Answer:
810 AUD
Step-by-step explanation:
t is time in months: you have to substitute with the number of months given from the question.
C=65t + 30 ==> substitute t with 12 since the question provided you the number of months.
--> C = 65(12) + 30 = 780 + 30 = 810

need help on math plz
Answer:
using Pythagoras theorem
9² = 7² + a²
81 - 49 = a²
[tex] \sqrt{32} = a[/tex]
5.65 = a
on rounding off it becomes 6 cm
Aline read a report saying 39% of teachers in the United State were members of a labor union. She wants to test whether this holds true for teachers in her state, so she is going to take a random sample of teachers and see what percent of them are members of a union. Let p represent the proportion of teachers in her state that are members of a union. Write an appropriate set of hypotheses for her significance test.
Answer:
H0: p= 0.39 vs Ha: p ≠ 0.39
Step-by-step explanation:
She wants to test whether this holds true for teachers in her state.
The test is the formulated into the hypotheses.
The null hypothesis would be
H0: p= 0.39 against the claim Ha: p ≠ 0.39
The null hypothesis tells that the the proportion of teachers in her state that are members of a union is equal to the proportion of teachers in the US that are members of the labor union.
against the claim
That the the proportion of teachers in her state that are members of a union is not equal to the proportion of teachers in the US that are members of the labor union.

Answer:
a) 677,040 b) 17,160
Step-by-step explanation:
a) this is a combinations problem as it deals with selection, rather than order. you can use a calculator to solve this:
there are 65 objects (colors) taken 4 at a time
(see photo)
there are 677,040 possible ways to arrange the boxes.
b) unlike question a, this is a permutation. the order matters.

Answer:
44/3
Step-by-step explanation:
Reduce 22/2 to 11, 3/9 to 1/3:
11(1/3)(4)
Working from left to right:
11(4)
------ = 44/3
3
Answer:
Step-by-step explanation:
simplify 22/2 then multiply it by 3/9
then multiply that answer by 4 and your total will be 14.6

6(2x - 11) + 15 = 3x + 12
Answer:
x = 7
Step-by-step explanation:
Lets do the brackets first,
6 × 2x = 12
6 × -11 = -66
------
Calculate the x constant:
12x - 3x = 9x
-------
Then the ones with no x:
-66 + 15 = -51
51 + 12 = 63
-------
Lastly, divide
63 ÷ 9 = 7

Which equations have no real solution but have two complex solutions?
A 3x>2-5=-8
b 2x>2=6x-5
c 12x=9x>2 +4
d -x>2 - 10x =34
Answer:
see details below
Step-by-step explanation:
First, assume >2 was meant to be &super;. or square.
then the given equations are:
A 3x^2-5=-8
b 2x^2=6x-5
c 12x=9x^2 +4
d -x^2 - 10x =34
In all cases, rearrange equation to identify parameters a, b and c, then calculate determinant using D=b^2-4ac.
A 3x^2x-5=-8
3x^2-5x+8=0, a=3, b=-5, c=8
D=b^2-4ac = (-5)^2-4*3*8 = 25 - 96 = -71 < 0 => 2 complex solutions
B 2x^2=6x-5
2x^2-6x+5, a=2, b=-6, c=5
D=b^2-4ac = (-6)^2-4*2*5 = 36 - 40 = -4 < 0 => 2 complex solutions
C 12x=9x^2 +4
9x^2-12x+4, a = 9, b=-12, c=4
D=b^2-4ac = (12)^2-4*9*4 = 144 - 144 = 0 => 2 real coincident solutions
D -x^2 - 10x =34
-x^2-10x-34, a = -1, b=-10, c=-34
D=b^2-4ac = (-10)^2-4*(-1)*(-34) = 100 - 136 = -36 <0 => 2 complex solutions
What is the mean of this set of numbers?
3, 7, 0, 3, 4, 0, 9, 1
Answer:
3.375 or 3.38 if rounded to the hundredths place.
Step-by-step explanation:
To get the mean of a set of numbers we add all the numbers in the set and then divide the sum by the amount of numbers in the set.
3+7+0+3+4+0+9+1= 27
Amount of numbers: 8
We divide 27 by 8.
27 ÷ 8= 3.375
3.375 is the mean, which we can round to 3.38 or further down to 3.4 for the tenths place and 3 for the ones place.

Answer:

Step-by-step explanation:
Mike borrowed a sum of rs 9450 for 5 years at a rate of 6% per year. calculate the total amount that he had to pay.
First year :
9450 + 9450 × ( 6 / 100 ) =
9450 + ( 9450 × 6 / 100 ) =
9450 + ( 56700 / 100 ) =
9450 + 567 =
Rs 10,017
_____________________________
Second year :
10,017 + 10,017 × ( 6 / 100 ) =
10,017 + ( 10,017 × 6 / 100 ) =
10,017 + ( 60,102 / 100 ) =
10,017 + 601.02 =
Rs 10,618.02
______________________________
Third year :
10,618.02 + 10,618.02 × ( 6 / 100 ) =
10,618.02 + ( 10,618.02 × 6 / 100 ) =
10,618.02 + ( 63,708.12 / 100 ) =
10,618.02 + 637.0812 =
Rs 11,255.1012
_______________________________
4th year :
11,255.1012 + 11,255.1012 × ( 6 / 100 ) =
11,255.1012 + ( 11,255.1012 × 6 / 100 ) =
11,255.1012 + ( 67,530.6072 / 100 ) =
11,255.1012 + 675.306072 =
Rs 11,930.407272
_______________________________
5th year :
11,930.407272 + 11,930.407272 × ( 6 / 100 )
=11,930.407272 +( 11,930.407272 × 6 / 100)
= 11,930.407272 + ( 71,582.443632 / 100 )
= 11,930.407272 + 715.82443632
= Rs 12,646.23170832
_______________________________
Thus Mike have to pay approximately Rs 12,646 after 5 years.
A =?
P= 9456
r = 6% = 0.06
t = 5 yrs
Formula
A= P(1+r)^t
A= 9456×1.06⁵
A = 12646.23
the total amount that he had to pay was 12646 rs

Find the length of the arc.
Answer:
1st option
Step-by-step explanation:
The length of the arc is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{210}{360}[/tex]
= 2π × 13 × [tex]\frac{21}{36}[/tex]
= 26π × [tex]\frac{7}{12}[/tex]
= [tex]\frac{26\pi (7)}{12}[/tex]
= [tex]\frac{182\pi }{12}[/tex]
= [tex]\frac{91\pi }{6}[/tex]

HELP WITH GEOMETRY SURFACE AREA, PAT ATTENTION TO THE DOUBLE SIDED RADIUS!!
Answer:
Half of 3 is 1.5(new radius)
1.5^2 = 2.25
2.25 x 3.14 = 7.065
7.065 x 2 = 14.13(area of two circles)
2 x 3.14 x 1.5 = 9.42
9.42(circumference) x 4(height) = 37.68(area of lateral)
Add the given areas:
37.68 + 14.13 = 51.81 cm2 is your answer.
if f(x) =2x-1 and g(x) =3x+2 find the fof(x)
=================================================
Explanation:
We won't involve the g(x) function at all.
We're composing the f(x) function with itself, which means we're replacing every x with f(x) and then simplifying.
See the attached image below for the steps.

6) x = 11; y = 11[tex]\sqrt{2}[/tex]
7) x = 9; y = 9
Step-by-step explanation:
please help! 20 points. if you guess or just comment to take my points i will make sure ur account gets banned. thanks! i want a simple explanation
Answer:
x = 9
Step-by-step explanation:
Of course I'll do very simple explanation!
every time you see a straight line (nondiagonal) it measures 180°.
so if we're trying to solve for x in this case, we'll subtract 180° - 40° = 140°.
Then use the statement to solve for x
[tex]10x+50=140[/tex]
[tex]10x-50[/tex] = - 50 Subtract 50 from both sides
[tex]10x[/tex] [tex]=[/tex] 90 Divide 10 from both sides
x = 9
