Answer:

The greater than sign (on my computer) is above the period key. So, just jit SHIFT then type the period key.

So, I guess you want to solve y^2 -3y > 18

We can factor that as y * (y -3) > 18

Well, if it is

y^2 -3y -18 = 0 then

Then y = 6 and y = -3

Hope that helps

Answer:

y > 6 or y < -3

Step-by-step explanation:

y² - 3y > 18

Complete the square.

y² - 3y + 9/4 > 18 + 9/4

y² - 3y + 9/4 > 81/4

(y - 3/2)² > 81/4

y - 3/2 > 9/2, or y - 3/2 < -9/2

y > 6 or y < -3

Consider a circle that has a circumference of 28/3.14 centimeters. What is the area of this circle? Answer fast plz also can you

bija089 [108]

Answer:

$A=6.33\ cm^2$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=\frac{28}{3.14}\ cm$

$\pi=3.14$

substitute the values

$\frac{28}{3.14}=2(3.14)r$

$r=\frac{28}{19.7192}\ cm$

$r=1.42\ cm$

step 2

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

substitute the values

$A=(3.14)(1.42)^{2}$

$A=6.33\ cm^2$

There were 700 people in the auditorium. 60% of them were adults and the rest were children. how many adults were in the auditor

ollegr [7]

$.60 \times 700 = 420 \\ 700 - 420 = 280$
First I found the number of adults by multiplying .60 by 700. It was 420. From there all I had to do was subtract it from 700. Revealing the number of children to be 280.
