ANSWER

Since probably part of the pie was already eaten therefore we find the fration of the pie in the beginning which is

= 1

= 5/5

Fraction William ate;

= 3/4 of 1

= 3/4 of 5/5

= 3/4 × 5/5

= 3/4

CONCLUSION

A fraction is a part of a whole so no matter how the fraction would increase or decrease the part William ate will remain the same

Answer:The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m<RST=(6x+12)\° -----> equation A

m<RST=78\°+(3x-12)\° -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

Advocard [28]

Answer:

72?-ft

Step-by-step explanation:

The tower shadow is 12 times as long as that of the post, so the tower will be 12 times as high as the post.

Answer:

The element you add is $b^2 / 4a$

Step-by-step explanation:

The element you add is $b^2 / 4a$

Remember that

$a x^2 + bx +c \\= a ( x^2 +(b/a)x ) + c$

So, in order to complete the square you add $(b/2a)^2$

But when you multiply times $a$ you get

$b^2 / 4a$

Consider the relation y = −8|x + 3| − 9. what are the coordinates of the vertex? (−3, 9) (−3, −9) (3, −9) (3, 9)

german

By simple substitution on the left side and on the right side of the given equation, we have to
For coordinates (-3,-9)
-9=−8|-3+3|−9
-9=−8|0|−9
 -9=−9
Therefore, it is demonstrated that the coordinates of the vertex is
(-3,-9)
