We use the BODMAS method to solve the given questions.
Solve the Bracket then Divide Multiply Add and Subtract
1. 32÷4×(16×1/2) - 2
= 32÷4 × ( 8 ) - 2
= 8 × 8 - 2 = 64 - 2 = 62
2. 20 ÷ (5×2/5) + 3
= 20 ÷ (2) + 3 = 20 ÷ 2 + 3
= 10 + 3 = 13
3. 1/2 ×(6×4) ÷ 3 + 2
= 1/2 × 24 ÷ 3 + 2
= 1/2 × 8 + 2
= 4 + 2 = 6
4. 2 (6÷2+8) - 4
= 2 (3+8) - 4
= 2 × 11 - 4
= 22 - 4
= 18
Answer:
yes
Step-by-step explanation:
because when there is a negative sign before the number, it means that the number being shown is below zero, so yes -8.4 degrees celsius is below zero degrees celsius.
Answer:
the answer would be 66 minutes
The second one which you would solve 5/20and -3/45
Tank Volume = length X Broad X height
So here Length is 8 m , broad is 3 m and let height is H m
So the volume of the tank will be = ( 8 X 3 X H ) m3
So ( 8 X 3 X H ) m3 = ( 8 X 3 X H ) X 1m3 , here 1 m3 = 1000 L
So the amount of water this tank can take is =
= (8 X 3 X H ) X 1m3
= (8 X 3 X H ) X 1000L
= 24000 X H L
And it is given that the tank is 14400L water ,
So we can calculate
24000 X H = 14400
So , H= 14400/24000
So , H = 0.6
So , Height of the tank is 0.6 m
