Answer:
x = 1425
Step-by-step explanation:
Given that,
A student found out that 8% of the students in his school are left-handed.
Total no of lefties = 114
We need to find the total number of students in the school. Let they are be x.
ATQ,
8% of x = 114
[tex]\dfrac{8x}{100}=114\\\\x=\dfrac{114\times 100}{8}\\\\=1425[/tex]
Hence, there are 1425 students in the school.
In 2006 the average ticket price for a national football league game was 62.38. Since then the cost has increased an average of $2.54 per year. Write a linear equation to represent the cost of C of an NFL ticket y years after 2006.
Answer:
y = 2.54x + 62.38
Step-by-step explanation:
Let x represent the duration or stipulated years after the year 2006
Let y represent the amount of ticket that is sold
Let m represent the average increase in the price every year
y = mx + c
y = 2.54 × x + 62.38
y = 2.54x + 62.38
Answer:
C=2.54y+62.38
c=2.54y+62.38
C=62.38+2.54y
or
c=62.38+2.54y

Answer:
27
Step-by-step explanation:
the sequence is 4 added to each number. 4 added to 23 is 27
Answer:
C.27
Step-by-step explanation:
We need to find the pattern in order to determine the next term of the sequence. By looking at the terms, we can observe that each one is 4 bigger than the previous term, therefore we can assume that the next term will also be 4 bigger than the last term we are given (23) so we add 4 to that (23+4) and we get 27.

An astronaut was exploring the moon of a distant planet, and found some glowing goo at the bottom of a very deep crater. She brought a 10-gram of the goo to her laboratory. She found that when the goo was exposed to light, the total amount of goo increased by 100% every hour. How much goo will she have sfter 1 hour?After 2 hours? After 3 hours? After n hours?
Answer:
20 ; 40 ; 80 ; 10(2^n)
Step-by-step explanation:
Given that:
Initial amount of goo (p) = 10 gram
Total amount of goo increased by 100% every hour ;
How much goo will she have sfter 1 hour?After 2 hours? After 3 hours? After n hours?
Using the relation :
Final amount = initial * (1 + rate)^t
Rate = 100% = 100/100 = 1
t = number of hours
Hence, after 1 hour :
Final amount = 10(1 + 1)^1
Final amount = 10(2)^1 = 20 grams
After 2 hours : t = 2
Final amount = 10(1 + 1)^2
Final amount = 10(2)^2 = 10 * 4 = 40 grams
After 3 hours ; t = 3
Final amount = 10(1 + 1)^3
Final amount = 10(2)^3 = 10 * 8 = 80 grams
After n hours ; t = n
Final amount = 10(1 + 1)^n
Final amount = 10(2)^n grams

The cost of a pair of shoes is Rs. 1000 . The GST charged was '5%' . Find the bill amount andalso find share of CGST, and SGST.
Answer:
Bill amount = Rs. 1050
CGST share = SGST share = Rs. 25
Step-by-step explanation:
We are told that the GST charged was 5% and cost of a pair of shoes is Rs. 1000. Thus;
Bill amount = 1000 + (5/100) × 1000
Bill amount = Rs. 1050
Now, CGST and SGST are both usually half of GST rate.
Thus;
CGST rate = SGST rate = 5%/2 = 2.5%
Thus;
CGST share = SGST share = 2.5% × 1000 = Rs. 25

Can sides of a triangle have lengths 3,4,9
Answer:
yes
Step-by-step explanation:
No, the lengths 3, 4, and 9 cannot form the sides of a triangle.
What is Triangle Inequality?The triangle inequality is a fundamental geometric principle that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
We have sides as 3, 4 and 9.
For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.
In this case, let's check if this condition is satisfied:
3 + 4 = 7
7 is less than 9
Therefore, these lengths do not satisfy the triangle inequality theorem, and a triangle cannot be formed with side lengths 3, 4, and 9.

If Fun Reads Bookstore has a ready club with a $40 fee and charges $5 per book and Cool Covers Bookstores club charges $100 fee and charges $2 per book how many books would you have to buy to make Cool Covers Bookstore club a better buy?
Answer:
You have to buy more than 20 books to make Cool Cover Bookstore club a better deal.
Step-by-step explanation:
Given that:
Fee charged by Fun Reads Bookstore = $40
Charges per book = $5
Let x be the number of books.
A(x) = 5x+40
Fee charged by Cool Covers Bookstore = $100
Charges per book = $2
B(x) = 2x+100
For making Cool Cover Bookstores club a better deal,
B(x) > A(x)
2x+100 > 5x+40
2x-5x > 40-100
-3x > -60
Dividing both sides by -3
[tex]\frac{-3x}{-3}>\frac{-60}{-3}\\x>20[/tex]
Hence,
You have to buy more than 20 books to make Cool Cover Bookstore club a better deal.
there are 10 boys and 20 girls in a class.
the class has a test.
the mean mark for the class is 60.
the mean mark for the girls is 54.
work out the mean mark for the boys.
Step-by-step explanation:
There are 10 + 20 = 30 total students in the class.
Total marks for the class = 60 * 30 = 1800.
Total marks for the girls = 54 * 20 = 1080.
=> Total marks for the boys = 1800 - 1080 = 720.
Mean mark for the boys = 720 / 10 = 72.
