Without doing the math, determine which is greater, 40 . 1/4 or 40/14. explain your reasoning

1 answer:

8 0

40 is greater because we can easily see that 1/4 is not a whole number that is less than 40 and the 40/14 will be changed into a lesser mixed number which again, is less than 40.

On a winter’s day, 9 degrees Fahrenheit is the highest temperature recorded. Write an inequality that represents the temperature

NemiM [27]

Answer: The inequality that represents the temperature t in degrees Fahrenheit at any time on this day is $t\leq 9$ degree Fahrenheit.

Explanation:

It is given that on a winter’s day, 9 degrees Fahrenheit is the highest temperature recorded. It means the temperature on this day must be less than or equal to 9 degree Fahrenheit.

Let t represents the temperature in degrees Fahrenheit at any time on this day. Then,

$t\leq 9$

Therefore, the inequality that represents the temperature t in degrees Fahrenheit at any time on this day is $t\leq 9$ degree Fahrenheit.

the diameter d of a fiber optic cable must be at least 4.8mm and at most 5.2mm. Write an absolute value inequality and a compoun

Marysya12 [62]

Using the absolute value function, we have that:

The absolute value inequality is: |x - 5| ≤ 0.2.

The compound inequality is 4.8 ≤ x ≤ 5.2.

<h3>What is the absolute value function?</h3>

The absolute function is defined by:

|x| = x, x ≥ 0.

|x| = -x, x < 0.

It measures the distance of a point x to the origin.

The diameter must be at least 4.8mm and at most 5.2mm, hence the compound inequality is:

4.8 ≤ x ≤ 5.2.

Another interpretation is that they are at most 0.2 mm from 5 mm, hence the absolute value inequality that models the situation can be given by:

|x - 5| ≤ 0.2.

Answer: 103/15

Step-by-step explanation:

We can simplify the right-hand side to be $2 \left(\frac{1}{3}+6 \right)=2 \left(\frac{19}{3} \right)=\frac{38}{3}$ .

This means we need to solve:

$\frac{1}{2}(5x-9)=\frac{38}{3}\\5x-9=\frac{76}{3}\\5x=\frac{103}{3}\\x=\boxed{\frac{103}{15}}$
