Well, a Centimeter is 10 times bigger than a Milimeter.
So we can convert 9cm by multiplying it by 10
9 × 10= 90mm
SInce we know the length and width of the rectangle, we can now find the area of it, or "the space inside".
Area = length × width
Area = 90mm × 81mm
Area = 7290mm
Answer:
there are 380 seats in total
Step-by-step explanation:
286 + 18 = 304 which is four-fifths of the seat. since 304 seats is 80% of the total seats then if you divide it by 80 then multiply it by 100 you get 380.
so one fifth would be 76 seats and if you multiply it by 4 you get 304 which is four fifths of the seat.
Answer:
72.1%
2
Step-by-step explanation:
Please give me brainliest, I really need it.
your number was 12.
let x be the number:
(x * 2) + 50 = 74
To solve for x, we need to reverse what was done to get the answer of 74.
Since 50 was added to arrive at 74, we deduct 50 from 74.
74 - 50 = 24
We then divide 24 by 2 to get the original number.
24/2 = 12.
Your number was 12.
To check:
(12 * 2) + 50 = 74
24 + 50 = 74
74 = 74
