Answer:
25 milliliters
Step-by-step explanation:
Given:
volume of sample = 100 ml
Syrup present in sample = 6.55 g per 20 mL
Therefore in 100 mL, amount of syrup present = 
or
amount of syrup present in 100 mL sample = 32.75 grams
Now,
Specific gravity of the syrup = 1.31
also,
Specific gravity of the syrup = 
or
1.31 = 
or
Density of syrup = 1.31 g/mL
also,
Density = 
therefore,
1.31 = 
or
Volume of syrup in the sample = 
or
Volume of syrup in the sample = 25 milliliters
Answer:
D
Step-by-step explanation:
using the definition of n
= 
where n! = n(n- 1)(n - 2)......× 3 × 2 × 1
here n = 7 and r = 4, hence
7
= 
= 
← cancel 3 × 2 × 1 leaving
7 = 7 × 6 × 5 × 4 = 840 → D
Answer:
-16+12= -4
Step-by-step explanation:
When we mins 12 from 16 (16-12) we get 4.
Similarly. When we minus 16 from 12 (12-16) we get -4 because we choose the sign with the greater number.
•sum of the angles in a triangle = 180°
•sum of the angle in a quadrilateral = 360°
•opposite angles are equal
•for two parallel lines and a transversal, corresponding angles are equal, and alternate angles are equal.
•If it already has an angle for a triangle subtract that by 180 and divide it by two you have the other two angle, if you already have two angles on a triangle add those together and subtract from 180 thats the last angle, same for a quadrilateral but you subtract by 360 instead.
