Answer:
Amount left = Rs 45
Step-by-step explanation:
Let the initial amount be x.
Translating the word problem into an algebraic expression, we have;
[tex] x - 15 = \frac {3}{4} * x [/tex]
[tex] x - 15 = \frac {3x}{4} [/tex]
Cross-multiplying, we have;
[tex] 4(x - 15) = 3x [/tex]
[tex] 4x - 60 = 3x [/tex]
Rearranging the equation (collecting like terms), we have;
[tex] 4x - 3x = 60 [/tex]
x = Rs 60
Next, we find the amount left;
Amount left = 60 - 15
Amount left = Rs 45

A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre. What is the smallest number of rows that is needed to seat these people?
Answer:
Smallest number of rows that is needed to seat these people = 16
Step-by-step explanation:
Given - A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre.
To find - What is the smallest number of rows that is needed to seat these people?
Solution -
Given that,
Total number of seats in a Row = 24
Let us assume that, there are x rows
As.
There are 382 people in the Theatre
So,
Minimum seats required is
24 x = 382
⇒x = 382 ÷ 24
⇒x = 15.91
i.e.
Smallest number of rows that is needed to seat these people = 16
The image below shows F with perpendicular tangent lines at points A and B.
Step-by-step explanation:
a) A & B are tangent points and that makes angle AFB = 90°
b) Since line DB is a diameter, that makes arcADB a semicircular arc.
c) We know that A & B are tangent points which makes the figure AFBC a square.

25/169
64/78.5
15/24
Answer:
The probability that a randomly placed point falls within the smaller, inner circle is 25/64
Step-by-step explanation:
The remaining part of question is attached
Solution
The area of smaller circle is
[tex]\pi r^2 = 25 \pi[/tex]
The area of large circle is
[tex]\pi r^2 = 64 \pi[/tex]
Area of the shaded region
Area of large circle - area of small circle
[tex]64\pi -25\pi = 39\pi[/tex]
Probability that the point falls in the region of smaller circle is
[tex]\frac{25\pi }{64\pi } \\\frac{25}{64}[/tex]

find three consecutive odd integers such that the sum of the last two is 15 less than 5 times the first
2n + 1 , 2n + 3 , 2n + 5
____________________________
( 2n + 5 ) + ( 2n + 3 ) = 5 × ( 2n + 1 ) - 15
4n + 8 = 10n + 5 - 15
4n + 8 = 10n - 10
Add both sides 10
4n + 8 + 10 = 10n - 10 + 10
4n + 18 = 10n
Subtract both sides 4n
4n - 4n + 18 = 10n - 4n
18 = 6n
Divide both sides by 6
18 ÷ 6 = 6n ÷ 6
n = 3

Johnny wants to buy a set of drums that cost $2000, it requires a 15% down payment. The remainder plus an additional finance charge is paid back on a monthly basis of 25 months. the monthly payment is $80. What is the finance charge.
Answer: The finance charge = $ 300
Step-by-step explanation:
Given: cost of drums = $ 2000
Down payment = 15% of 2000
= 0.15 x 2000
= $300
Total installments = (Number of months) x (Monthly charge)
= 25 x $ 80
= $ 2000
Finance charge = Down payment + Total installments - cost of drums
= $ (300+2000-2000)
= $ 300
Hence, the finance charge = $ 300
