Can't see the figure, but the basic way to solve this problem is to use the formula for volume of a pyramid which is (length * width * height )/3. Slant height is just the square root of ((length/2)2 + height2) recognizing that there is a right triangle there. Since slant height increased by 4 cm when its height increased by 2cm, you know that the length/2 term had to increase by the square root of 12 (22+root(12)2) = 42=16. From there you can figure out the rest pretty readily.
Answer:
kg/ m³
Step-by-step explanation:
Since density is= 
, where mass is in kg and volume is in cm³, the unit of density would follow so it is kg/m³.
Answer:
- 3/8
Step-by-step explanation:
−9/24 −3/8= 3/8−3/4
=(3×4)−(3×8) = 8×4 = 12−24= -12/32 =−3/8
32

Answer:
hey can you make it more clear
Step-by-step explanation:
830=52x
830/52=52x/52
Hence x = 15.96
Example:
<span>12 is 20% of 60. In order to get 12 percent of 60, all you need to do is to divide 12 with 60. To get the percent means to get the parts of 100. To get it in the form of percent, just multiply the quotient by 100. 12/60=.2 x 100 = 20% .</span>
