The general form of a polynomial expression is
[tex]a_{n}[/tex][tex]x^{n}[/tex] + [tex]a_{n-1}[/tex][tex]x^{n-1}[/tex] + [tex]a_{n-2}[/tex][tex]x^{n-2}[/tex] + ............ + a₁[tex]x^{1}[/tex] + a₀
For the given polynomial the [tex]x^{n}[/tex] term is - [tex]x^{13}[/tex] , that is n = 13 , thus
n - 7 = 6 , that is the [tex]x^{6}[/tex] term
with [tex]a_{n-7}[/tex] being its coefficient
Since there is no [tex]x^{6}[/tex] term, then its coefficient is zero, that is
[tex]a_{n-7}[/tex] = 0 → C
Mr Hassan spent 1/3 of his salary on food and 2/5 of the remainder on transport. What fraction of his salary was left?
Answers
Answer:
4/15 was left over from is salary.
Step-by-step explanation:
Common denominator is 15. 5/15+6/15= 11/15.
15/15-11/15= 4/15.
If Mr Hassan spent 1/3 of his salary on food and 2/5 of the remainder on transport then 4/15 fraction of his salary was left.
What is Fraction?A fraction represents a part of a whole.
Let us consider the salary of Hassan as 1.
Mr Hassan spent 1/3 of his salary on food
2/5 of the salary on transport.
We need to find the fraction of his salary left.
We need to subtract 1/3 and 2/5 from 1
1-1/3-2/5
LCM of 3 and 5 is 15
15-5-6/15
4/15
Hence, 4/15 is the fraction of Hassan salary was left

if john run 2.5 miles everyday, how many miles will he run in a month of 30?
Answers
Answer:
2,250 miles per day.
Step-by-step explanation:
John runs 2.5 miles per day. In a period of 30 months, you can averagely take 30 days in each month.
So, 30 x 30 = 900 days in 30 months.
To find the number of miles ran in 900 days,
900 x 2.5 = 2,250 miles per day.

A contractor purchases 5 dozen pairs of padded work gloves for $67.20. She incorrectly calculates the unit price as $13.44 per pair for the expense report. What is the correct unit price? What is the error?
Answers
Answer:
13.44
Step-by-step explanation:
she is right...........
Answer:
The correct unit price is $1.12 per pair. The error comes from dividing $67.20 by only 5 pairs (instead of 60 pairs).
Step-by-step explanation:
The contractor should have calculated the unit price as $67.20 divided by 60 pairs. Five dozen pairs is 5x12=60. This results in $67.20/60=$1.12 per pair. The error comes from dividing $67.20 by only 5 pairs (instead of 60 pairs).

The blues band, Jonny and the Silver Toads, charges $25 per ticket at their performances. Their next venue charges them $900 for use of the venue. Based on the inequality below, how many tickets, , do they need to sell in order to profit at least $1,925?
Answers
Answer:
The band must sell at least 113 tickets to make a net profit of at least $ 1,925.
Step-by-step explanation:
While the band charges $ 25 for each entrance ticket to their performances, and the venue charges them $ 900 for the use of the place, the number of tickets that must be sold for the band to obtain a profit of at least $ 1,925 arises from the following calculation:
1,925 + 900 = Costs plus profit
2,825 / 25 = Number of tickets needed to cover costs and profit
113 = Number of tickets needed to cover costs and profit.
Therefore, the band must sell at least 113 tickets to make a net profit of at least $ 1,925.

find the percent of the number

Answers
Answer:
115.2
Step-by-step explanation:
Answer: 115.2
Step-by-step explanation:
What is 24% of 480?
Y is 24% of 480
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 24% * 480
Converting percent to decimal:
p = 24%/100 = 0.24
Y = 0.24 * 480
Y = 115.2

Answer:
[tex]y = 50x[/tex]
Step-by-step explanation:
Let's start off by trying to find the slope/gradient (commonly denoted as [tex]m[/tex]) of this function
[tex]m = \frac{\Delta y}{\Delta x}[/tex]
This means we divide the change in y over the change in x
Let's pick, for example, x = 3 (who's corresponding y is 150) and x = 4 (who's corresponding y is 200)
[tex]m = \frac{200 - 150}{4 - 3}\\\\m = 50[/tex]
Now we have this:
[tex]y = 50x+b[/tex]
Let's plug in a random value of x and y from this function in order to find b. I'll pick x = 2:
[tex]100 = 50\cdot 2 + b\\100 = 100 + b\\b = 0[/tex]
Since b is 0, we don't have to write it on our equation, meaning that our final equation is just
[tex]y = 50x[/tex]
To verify this, let's say we didn't know the value of y when x is equal to 4 and all we had was that equation:
[tex]y = 50\cdot 4\\y = 200[/tex]
Just like it is on the graph :)
Good luck!

Harloe’s cats love Christmas songs. Every day she sings “Jingle Bells” five times, “Silver Bells” twice as many times as “Jingle Bells” and “Silent Night” once before bedtime.
A. How many songs does Harloe sing each day?
B. How many songs does Harloe sing in the weekend?
Answers
Answer:
A- 16 songs a day
B- 32 songs in the weekend
Step-by-step explanation:
A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying 5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day
B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32
Silver bells= 2x5
Silent night=1
5x7=35
10x7=70
1x7=7
35+70+7=112 songs every week
For the weekend:
5x2=10
10x2=20
1x2=2
10+20+2= 32 songs on the weekend
In ∆TMZ, the measure of angle M is 6° more than twice the measure of angle T, and the measure of angle Z is 50° less than five times the measure of angle T.
Answers
Answer:
m<T = [tex]28^{o}[/tex], m<M = [tex]62^{o}[/tex] and m<Z = [tex]90^{o}[/tex]
Step-by-step explanation:
From the given ∆TMZ, let the measure angle T be represented by T.
So that,
m<M = 2T + 6°
m<Z = 5T - 50°
Sum of angles in a triangle = [tex]180^{o}[/tex]
T + (2T + 6°) + (5T - 50°) = [tex]180^{o}[/tex]
8T -[tex]44^{o}[/tex] = [tex]180^{o}[/tex]
8T = [tex]180^{o}[/tex] + [tex]44^{o}[/tex]
= [tex]224^{o}[/tex]
T = [tex]\frac{224^{o} }{8}[/tex]
= [tex]28^{o}[/tex]
Therefore,
i. m<T = [tex]28^{o}[/tex]
ii. m<M = 2T + 6°
= 2 x [tex]28^{o}[/tex] + 6°
= [tex]62^{o}[/tex]
m<M = [tex]62^{o}[/tex]
iii. m<Z = 5T - 50°
= 5 x [tex]28^{o}[/tex] - 50°
= [tex]140^{o}[/tex] - 50°
= [tex]90^{o}[/tex]
m<Z = [tex]90^{o}[/tex]
