The expression 3(r/t) "the quotient of three times a number, and 7 option (C) 3(r/t) is correct after applying the arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The expression is:
The quotient of three times a number and 7
Let the two numbers be r and t:
On division:
= r/t
= 3(r/t)
Thus, the expression 3(r/t) "the quotient of three times a number, and 7 option (C) 3(r/t) is correct after applying the arithmetic operation.
The missing options are:
3 + rt

HELP: find the measure of the arc or angle indicated, assume that lines which appear tangent are tangent
Answer:
3) B. 65°4) D. 120°Step-by-step explanation:
Question 3Angle formed outside is half of the difference of intercepted arcs
m∠F = 1/2(( 360° - 115°) - 115°) = 1/2(130°) = 65°Correct choice is B
Question 4Angle formed by two chords is half of the sum of intercepted arcs
m∠WTU = 1/2(105° + 135°) = 1/2(240°) = 120°Correct choice is D

keith buys 6 pencils for 90p
how much does one pencil cost?
how much would five pencils cost
how much would eleven cost ?
Answer:
1 Pencil = 15p
5 Pencils = 75p
11 Pencils = 165p --> £1.65
Step-by-step explanation:
To find one pencil... 90 / 6 = 15
To find 5 pencils... 15 (worth 1 pencil) * 5 = 75
To find 11 pencils... 15 (worth 1 pencil) * 11 = 165 which is £1.65
Ethen is ‘x’ years old. Raj is 8 years older than Ethen. Find the sum of their ages in 6 years time.
Answer:
The sum of their ages in 6 years time is (2x+20) years.
Step-by-step explanation:
Given that,
Ethen is ‘x’ years old.
Raj is 8 years older than Ethen.
Raj's age = (x+8) years
We need to find the sum of their in 6 years.
After 6 years,
Ethen's age = (x+6) years
Raj's age = (x+8)+6
= (x+14) years
Sum of ages = (x+6) + (x+14)
= 2x+20
Hence, the required answer is (2x+20) years.

If 400,000 tourists contribute $67 million to a local economy, how much would 600,000 tourists contribute?
Answer:
[tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
Step-by-step explanation:
Given that,
400,000 tourists contribute $67 million to the local economy.
We need to find how much would 600,000 tourists contribute.
400,000 tourists = $67 million
1 tourist = [tex](\dfrac{67}{400,000 })\ \text{million}[/tex]
So, 600,000 tourists contribution is :
[tex]600000\ \text{tourists}=(\dfrac{67}{400,000 })\times 600000\ \text{million}\\\\=100.5\ \text{million}[/tex]
Hence, [tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
