Answer:
There are 3 possible values for a.
Step-by-step explanation:
a/b=2/3
3a=2b
If b>5 and b<13
apply all possible values
b=6 -> 3a=12 ==> a=4 1st possibility
b=7 -> 3a=14 ==> a=4.something Not a possibility
b=8 -> 3a=16 ==> a=5.something Not a possibility
b=9 -> 3a=18 ==> a=6 2nd possibility
b=10 -> 3a=20 ==> a=6.something Not a possibility
b=11 -> 3a=22 ==> a=7.something Not a possibility
b=12 -> 3a=24 ==> a=8 3rd possibility

Tatia, Mary, and Erica were partners in business. Tatia received twice as much of the profit as Erica received. Mary received 2/3 of the amount Tatia received. If the total profit was $52,000, how much did Mary recieve
Answers
Answer:
$16000
Step-by-step explanation:
let Amount Erica received be 'x'
Tatia received = 2x
Mary received = 2/3(2x) = 4x/3
x + 2x + 4/3(x) = 52000
3x + 4x/3 = 52000
(9x+4x)/3 = 52000
13x/3 = 52000
x = (52000 x 3) / 13
x = 4000 x 3
x = 12000
Mary Received = 4x/3 = 4(12000)/3 = 16000
Answer:
$16000
Step-by-step explanation:
erica would get -n
tatia gets -2n
Mary gets -2/3 of 2n
2n +( 2/3 of 2 n ) + n =$52000
2n + 4/3n+ n=$52000
3 4/3 n=$52000
13/3 n= $52000
n= $16000
4000 people were randomly selected for a survey. It was found that 50% read the newspapers in Nepali language, 45% read the newspapers in English language and 25% read neither of them. How many families read the both? Also, find the number of families who read exactly one kind of these papers. +
Answers
Answer:
1) 800 (read the both) 2) 2200 (read exactly one)
Step-by-step explanation:
Find the people (families) who read neither of them
4000/100*25= 1000
It means that the rest 4000-1000= 3000 families read the newspapers at least in one language from the pointed languages. 4000/1oo*50= 2000 - readers in Nepali
4000/100*45= 40*45=1800 - readers in English.
2000+1800= 3800- the special amount, that consists of 1) only Nepali readers
2) only English readers 3) the readers in two languages (but the were counted twice, because we considered them in the group of Nepali readers and group of English readers)
The real quantity of only Nepali readers, only English readers and both language readers is 3000.
S0 3800-3000= 800 people - read in two languages
3000-800=2200 families read exactly one kind of these papers

Step-by-step explanation:

The conditional relative frequency table by column
We have:
[tex]\begin{array}{cccc}{} & {Looking\ for\ job} & {Not\ looking} & {Total} & {Employed} & {12} & {28} & {40} & {Not\ Employed} & {38} & {72} & {110}& {Total} & {50} & {100} & {150} \ \end{array}[/tex]
To get the conditional frequency by column, we simply divide each cell by the corresponding total value (on the last row)
So, we have:

Find the first term and the common difference of the arithmetic sequence whose 6th term is 30 and 12th term
is 54.
Answers
Answer:
10 and 4Step-by-step explanation:
The first term is a, common difference is d.
The 6th term:
a + 5d = 30The 12th term:
a + 11d = 54Solve the system by elimination:
11d - 5d = 54 - 306d = 24d = 4Find a:
a + 5*4 = 30a + 20 = 30a = 10Answer:
Given :-6th term = 30
12th term = 54
To Find :-First term
Common difference
Solution :-We know that
[tex] \sf \: a_{n} = a + (n - 1)d[/tex]
For 6th term
[tex] \sf \: 30 = a + (6 - 1)d[/tex]
[tex] \sf \: 30 = a + 5d[/tex]
For 12th term
[tex]\sf \: a_{n} = a + (n - 1)d[/tex]
[tex] \sf \: 54 = a + (12 - 1)d[/tex]
[tex] \sf \: 54 = a + 11d[/tex]
On subtracting both
[tex] \sf \: 54 - 30 = a + 11d - (a + 5d)[/tex]
[tex] \sf \: 54 - 30 = a + 11d - a - 5d[/tex]
[tex] \sf \: 24 = 6d[/tex]
[tex] \sf \: \dfrac{24}{6} = d[/tex]
[tex] \sf \: 4 = d[/tex]
Now
Using 2
[tex] \sf \: 54 = a + 11d[/tex]
[tex] \sf \: 54 = a + 11(4)[/tex]
[tex] \sf \: 54 = a + 44[/tex]
[tex] \sf \: 54 - 44 = a[/tex]
[tex] \sf \: 10 = a[/tex]
What are the root(s) of the quadratic equation whose related function is graphed below?
Answers
Answer:
0 and 4
Step-by-step explanation:
roots are where the graph intersects at x axis
The roots of the quadratic equation whose related function is graphed are 0 and 4, the correct option is C.
What is the quadratic equation?A quadratic equation is a second-order equation written as ax2 + bx + c = 0 where a, b, and c are coefficients of real numbers and a ≠ 0.
If b2 – 4ac > 0 roots are real and different. As the discriminant is >0 then the square root of it will not be imaginary. It has two cases.
If b2 – 4ac is a perfect square then roots are rational. As the discriminant is a perfect square, so we will have an integer as a square root of the discriminant. Hence, the roots are rational numbers.
The shape of the graph is a downward parabola on the positive x-axis therefore the roots of the graph are positive.
From the given option the roots of the equation are 0 and 4 both are positive.
Hence, the roots of the quadratic equation whose related function is graphed are 0 and 4.

What is simple interest?Simple interest is a quick and easy method of calculating the interest charge on a loan.
What is the formula for calculating the simple interest?The formula for calculating the simple interest is
[tex]Simple\ interest = \frac{P\times R\times T}{100}[/tex]
Where,
P is the principal amount
R is the interest rate
And, T is the time in years
According to the given question.
Principal amount, P = $18,000
Interest rate, R = 6.8%
Time, T = 4 years
Therefore,
The monthly loan payments, we calculate the simple interest for monthly
= [tex]\frac{18000 \times 6.8\times 4}{100 \times 12}[/tex] = $408

find the interior angle sum for the following polygon.
Answers
We know that the interior angle sum of a polygon is (n − 2) × 180°, where n is the number of sides.
Here, number of sides (n) = 12
So, interior angle sum = (n − 2) × 180°
=> interior angle sum = (12 - 2) × 180°
=> interior angle sum = 10 × 180°
=> interior angle sum = 1800°
So, the interior angle sum of this polygon is 1800°.
