The quotient of a number t and 4.2 is at most 15.​
frosja888 [35]

Answer:

t \leq 63

Step-by-step explanation:

Quotient of two numbers also means the result of the two numbers after division.

If the quotient of a number t and 4.2 is at most 15., this can be expressed using the inequality;

\dfrac{t}{4.2}\leq  15 <em>(note that at most 15 means that the highest value we can have is 15 after taking the quotient of the number hence the reason of the inequality sign.)</em>

<em></em>

On solving the inequality for the variable t

\dfrac{t}{4.2}\leq  15\\\\multiply \ both \ sides \ by \ 4.2\\\\\dfrac{t}{4.2}* 4.2\leq  15 * 4.2\\\\t \leq 63

<em>Hence t is at most 63</em>

Express 10.9090909091... as a rational number, in the form pq where p and q are positive integers with no common factors.
Alexeev081 [22]
Firts, Let x be the repeated decimal that we are trying to convert , so x=10.9090909090 equation (1)

Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:
100x=1090.90909090 (2)

Subtract equation (1) from equation (2):
100x-x=1090.90909090-10.90909090
99x=1080

Solve for x
x= \frac{1080}{99}

We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>\frac{1080}{99}.
