Answer:

  • Simplified inequality: x < 7/2

Solution:

First, let's simplify the inequality to obtain the simplified inequality. Then, let's graph it.

  • => 4x² - 49 < 0
  • => 4x² - 49 + 49 < 0 + 49
  • => 4x² < 49
  • => 4x²/4 < 49/4
  • => x² < 49/4
  • => √x² < √49/4
  • => x < √7 × 7/2 × 2
  • => x < 7/2

<u>Now, let's graph the inequality.</u>

emily leaves her house at exactly 8:25 am to bike to her school, which is 3.42 miles away. when she passes the post office, whic
NNADVOKAT [17]
We first calculate Emily's rate by dividing the distance from her home to the post office by the time it took her to travel that distance. From 8:25 to 8:29 (and 30 seconds), there are exactly 4.5 minutes. Thus, the rate is equal to,
                                   r = (0.75 miles) / (4.5 minutes) = 1/6 miles/min
Then, we divide the given distance from her home to school by the calculate rate to determine the total number of minutes it will take her to travel to school.
                               t = (3.42 miles)/(1/6 miles/min) = 20.52 minutes
Adding this to 8:25 will give us an answer of 8:45 and 31.2 seconds. She will not be late.

An automotive repair center charges $45 for any part of the first hour of labor, and $25 for any part of each additional hour. W
Lena [83]
To answer this question, it is easier to make a list of the repair cost based on the hour of labor. The first hour is $45 then after that $25/hour. Then the list would look like 

0-1 h= $45
1-2h= $70     ($45 +1*$25)
2-3h= $95    ($45 +2*$25)
3-4h= $120   ($45 +3*$25)

Looking at the list, the answer should be
<span>B. C(t) = 95 for 2 < x ≤ 3</span>

Ira Lisetskai [31]

Answer:

Esophagoscopy

Step-by-step explanation:

In medical terminology roots, suffices and prefixes in Latin and ancient greek are commonly used to describe symptoms, deceases, etc. this terminology is achieved thanks to Etymology, the study of the history of the words, the origin of them. Usually refixes don't require further modification to be added to a word root because the prefix normally ends in a vowel or vowel sound, suffixes are attached to the end of a word root to add meaning such as condition, disease process, or procedure.

Taking this into account we look for the Latin of viewing from the ancient Greek, "scopeo", wich means, "to see", and then modify it as a termination suffix "-scopy"  and finally, we unify both words into one: esophagoscopy

I hope you find this information useful and interesting! Good luck!

One number is nine more than another number. If the sum of numbers is 65, find both numbers
Otrada [13]

Answer:

The Answer is that the first number is 37 and the second number is 28.

Step-by-step explanation:

Let f = first number and s = second number

f = s + 9

The sum of both numbers is 65:

f + s = 65

Substitute:

(s + 9) + s = 65

2s + 9 = 65

2s = 65 - 9

2s = 56

s = 56 / 2 = 28, the second number.

f = s + 9

f = 28 + 9 = 37, the second number.

Proof:

f + s = 65

28 + 37 = 65

65 = 65

Here you go! Hope this helps and have an Awesome Day!! :-)
