9= h/9
Mutiply both sides by 9
9*9= h/9*9
Cross out 9 and 9 , divide by 9 and then becomes h
9*9= 81
Answer: h= 81
B. Since she has to divide the number of pictures with how many pages
Answer:-30
Step-by-step explanation:kinda hard to tell a little shaky so sorry if it is wrong.
Tan ( A - B ) = ( tan A - tan B ) / ( 1 + tan A tan B )
tan A = 3 tan B/2
tan ( A - B ) = ((3 tan B/ 2)-tan B) / ( 1 + 3 tan² B/2)=
= (tan B/2) / ( 2 + 3 sin²B/cos²B )=
= (sin B / cos B) / (( 2cos² B+3sin²B)/cos²B)=
=( sin B cos B ) / ( 2 cos²B + 3 ( 1 - cos² B ) ) =
= (sin B cos B ) / ( 2 cos² B + 3 - 3 cos² B ) =
= ( sin 2 B ) / 2 ( 3 - cos² B ) =
= ( sin 2 B ) / ( 6 - cos² B )=
= ( sin 2 B ) / ( 5 + 1 - 2 cos² B )=
= ( sin 2 B ) / ( 5 + sin² B + cos ² B - 2 cos² B ) =
= ( sin 2 B ) / ( 5 - ( cos² B - sin² B ) ) =
= ( sin 2 B ) / ( 5 - cos 2 B ) - correct
Answer:
Step-by-step explanation:
28 students all give $128
so,
![\sqrt[28]{128}](https://tex.z-dn.net/?f=%5Csqrt%5B28%5D%7B128%7D)
= v v=6
Each student gave 6 dollars. This is true due to the fact that
=6
28X6=128
