The answer is 45 because 36 as a fraction is 36/w (the w is a variable) and 80% is 80/100, then cross multiply 36 x 100 is 3600 and 80 x w is 80w. Divide by 80 and you get 45. :)
Answer:
When I solve it , I got the answer not the same with you.
( i ) The lateral area of the prism is 204.
( ii ) The total surface area of the prism is 744.
Step-by-step explanation:
( i ) We got that answer because we multiply 17 cm with 12 cm.
( 17 x 12 )
Because it ask only ask for the lateral area which is length and width.
Lateral means side or side so it is length and width not height and
width/length.
( ii ) We got that answer because first step we multiply 17 cm with 12 cm.
We also have to multiply the gotten answer with 2.
Second step, we multiply 12 cm with 7 cm. Almost gonna forgot,
we also have to multiply the gotten answer with 4. Then, add the first
step and second step to make the total surface area.
= ( 17 x 12 x 2 ) + ( 12 x 7 x 4 )
= ( 204 x 2 ) + ( 84 x 4 )
= 408 + 336
= 744

Answer:
Let the 2nd fraction be a/b then according to question,
1st fraction is 4a/3b
Now,
4a/3b-a/b=2/9
(4a-3a)/3b=2/9
a/3b=2/9
compairing corresponding elements of fraction,
a=2
And,
3b=9
b=3
It would be 41.14.
just change the mixed number into improper fractions and plug it into the calculator.
