Answer:
Step-by-step explanation:
The LCM of 14, 21 and 6 is 42
We require to change the fractions to fractions with a denominator of 42
+ 
+ 
= 
+ 
+ 
← add the numerators, leaving the denominator
= 
= 
← divide both values by 2
= ← in simplest form
The answer for this is 3 and 4
<span>In the figure, all the dimensions of the cuboid
a = 4/5m side of the base
b = 1/3m second side of the base
c = h = 1/4m height solid
The volume is the product of the edge
V = abc = 4/5m * 1/3m * 1/4m = 4/60m</span>³ = 1/15m³
Answer B
2.0076* 10^4
move the decimal 4 places to the right
20076.
20076 < 26970
The distance ( S ) is represented by the equation:
S ( t ) = - 16 t² + 25
- 16 t² + 25 = 0
- 16 t² = - 25 / · ( - 1 )
16 t² = 25
t ² = 25 / 16
t = √( 25/16) = 5/4 = 1.25 s ( we will not accept the negative value )
