Answer:
height = 7 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A = 
h(a + b)
where h is the height and a, b the parallel bases
here a = 6, b = 12 and A = 63, hence
× h × (6 + 12) = 63
h × 18 = 63
9h = 63 ( divide both sides by 9 )
h = 7
Answer:
24
Step-by-step explanation:
3/8=9
6/8=18
8/8 would be 6/8 plus 2/3 of nine which is six
6+18=24
245 divided by 49 = 5 therefore there are 5 seats in each row.
Answer(s):
Exact Form: x + 2 y − 3 z = 15 , 2 x − 2 z = 6 , 3 2 3
Mixed Number Form: x + 2 y − 3 z = 15 , 2 x − 2 z = 6 , 3 2 3
Improper Fraction Form: x + 2 y − 3 z = 15 , 2 x − 2 z = 6 , 11 3
Decimal Form: x + 2 y − 3 z = 15 , 2 x − 2 z = 6 , 3. ¯ 6
Hope this helps, have a nice day/night! :D
To find the answer, you need to divide 90.5 by 4. The answer to that is 22.625, and if you want to check the answer, 22.625 x 4 = 90.5. Hope this helps :)
