Samples of simulated lake water are exposed to SO2(g). Two graduated cylinders containing samples of simulated lake water had CaCO3(s) added, and dissolves to form Ca2+ ions and CO32- ions. The chemical reaction of water exposed to SO2(g) is:H2O(l) + S02(g) --> H2S04(aq) (sulphuric acid) , producing Hydronium ions in solution. Hydronium ions react with the CO32- ions which then produces,options:HCO3-(aq) (weak acid)H2CO3(aq) (weak acid)HCO3-(aq) (strong acid)H2CO3(aq) (strong acid)

The co ordinates of the points of a line segment in the ratio 2:1​

Answer»

ANSWER:

Using the section formula, if a point (X,y) divides the line joining the points (X1,y1) and (X2,Y2) internally in the ratio m:n, then (x,y)=(m+nmx2+nx1,m+nmy2+ny1)

Substituting (x1,y1)=(−2,1) and (x2,y2)=(1,4)  and m=2,n=1 in the section formula, we get the

point (2+12(1)+1(−2),2+12(4)+1(1))=(0,3)

7. In Rohan's birthday party, 90% of his friends came and three friends did not come. Findthe total number of friends Rohan has.​

Answer»

Answer:

Rohan has 30 FRIENDS.

Step-by-step explanation:

Given:

Friends came = 90% of total friends

Friends who didn't come = 3

To find :

Total NUMBER of friends Rohan has

Solution :

LET the total number be y.

As 90% came,

⇒ 100 - 90

⇒ 10%

10% didn't come

It is also given that 3 friends didn't come.

⇒ 10% of y = 3

⇒ 10/100 × y = 3

⇒ 10y = 3 × 100

⇒ 10y = 300

⇒ y = 300/10

⇒ y = 30

Total Friends = 30

Friends who attended the party -

⇒ 90% of 30

⇒ 90/100 × 30

9/10 × 30

⇒ 9 × 3

⇒ 27

27 friends attended the party.

Therefore, Rohan has 30 friends.
