Answer:
Porosity of the sand is, 20 %.
Step-by-step explanation:
So according to the question,
10 mL of sand contains (5 - 3) mL = 2 mL of water and this water fills the gaps or pores between the sand partcles. So, porosity of the sand is given by,
%
= 20 %
a. 
b. 
c. 
Step-by-step explanation:
Step 1; First, we convert the given fractions into improper ones. To do this, we multiply the whole number with the denominator of the fraction and add with it the same fraction's numerator whereas the denominator remains unchanged. To convert the fraction
3
= (3 × 4) + 1 / 4 =
,
2
= (2 × 3) + 1 / 3 =
,
6
= (6 × 5) + 1 / 5 =
,
4
= (4 × 4) + 1 / 4 =
,
5
= (5 × 7) + 2 / 7 =
,
4
= (4 × 3) + 1 / 3 =
.
Step 2; Now we subtract, using LCM to arrive at the answer

Answer:
m<2 = 4x - 26 = 4(30) - 26 = 94 degrees
m<3 = 3x + 4 = 3(30) + 4 = 94 degrees
Step-by-step explanation:
Congruent angles are equal, so m<2 = m<3
4x - 26 = 3x + 4
x = 30
m<2 = 4x - 26 = 4(30) - 26 = 94 degrees
m<3 = 3x + 4 = 3(30) + 4 = 94 degrees
