This is something about absolute value but i have no idea how to do it
Advocard [28]

You're looking for an inequality of the form |t-b|\le a, or -a\le t-b\le a, or b-a\le t\le b+a.

Start with

350^\circ\le t\le400^\circ

Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get

-25^\circ\le t-375^\circ\le25^\circ

so we can set a=25^\circ and b=375^\circ, and we can rewrite this inequality in terms of absolute values as

|t-375^\circ|\le25^\circ

The answer is 37 200.

Step-by-step explanation:

The steps are :

x² - y² = (x + y)(x - y)

193² - 7² = (193 + 7)(193 - 7)

= (200)(186)

= 37 200

Answer: 510 flights

Step-by-step explanation:
85% are expected to arrive on time, so we can convert that to a decimal, which is 0.85. (To convert a percentage to a decimal we can divide by 100.)

After this we take the TOTAL AMOUNT OF FLIGHTS x 0.85
Total Amount = 600

600 x 0.85 = 510.
