Answer: A
Step-by-step explanation:
Given :
A cuboid shaped tank with sides 3.2 cm , 2.8 cm and 1.6 cm.
To Find :
The volume of the tank.
Solution :
We know, volume of a cuboid is given by product of its sides or :
Therefore, the volume of the tank is 14.336 cm³ .
Answer:
To be able to determine the unknown range of the number with tolerance given, first we need to determine the 4% of 500. This can be done by multiplying 500 by the decimal equivalent of 4% which is equal to 0.04.
tolerance = (500) x (0.04) = 20
Lower limit: The lower limit is determined by subtracting 20 from 500.
Lower limit = 500 - 20 = 480
Upper limit: The upper limit is determined by adding 20 to the base value 500.
Upper limit = 500 + 20 = 520
The values, therefore, rang from 480 to 500.
<em>ANSWER: 480 - 520</em>
Answer: (1) 7:5 (2) 2:9 (3) 3:4
<u>Step-by-step explanation:</u>
cross multiply to get: 7a = 5b
ratio = 7:5
*************************************
2a = 9b
ratio = 2:9
************************************
6a - 3b = 5b
<u> +3b</u> <u>+3b </u>
6a = 8b
<u>÷2 </u> <u> ÷2 </u>
3a = 4b
ratio = 3:4
