If for an A.P.,d=11 then t₁₇-t₁₅= ….....2 pointsa) 2b) 22c)33d) 13

Answer»

Answer:

B)22

Step-by-step explanation:

Given that,

Common difference=d=11

first term=a=a

number of the term=N

T

n

=a+(n−1)d

T

17

=a+(17−1)11

=a+(16)11

=a+176

T

n

=a+(n−1)d

T

15

=a+(15−1)11

=a+(14)11

=a+154

then,

T

17

−T

15

=(a+176)−(a+154)

=a+176−a−154

=22

Thus,

We get A.P=22

25322.	3. The measures of angles of a triangle are x°,(x-20), (x-40)Find the measure of each angle.
Answer» Given :- Measure of 1ST angle :- X° Measure of 2nd angle :- x -20° Measure of 3rd angle :- x - 40° We KNOW that SUM of three angles of a triangle is 180° So, simply we will add up all the angles and equal to 180. We will get the value of x Then, simply we can SUBSITUTE values → x + x - 20 + x - 40 = 180 → x + x + x - 20 - 40 = 180 → 3x -60 = 180 → 3x = 180 + 60 → 3x = 240 → x = 240/3 → x = 80 Thus, we got the value of x i.e 80 Subsituting Values :- Measure of 1st angle = x = 80° Measure of 2nd angle = x - 20 = 80 - 20 = 60° Measure of 3rd angle = x - 40 = 80 - 40 = 40° ━━━━━━━━━━━━━━━━━━━━━━━━━━

3. The measures of angles of a triangle are x°,(x-20), (x-40)Find the measure of each angle.

Answer»

Given :-

Measure of 1ST angle :- X°
Measure of 2nd angle :- x -20°
Measure of 3rd angle :- x - 40°

We KNOW that SUM of three angles of a triangle is 180°

So, simply we will add up all the angles and equal to 180.

We will get the value of x

Then, simply we can SUBSITUTE values

→ x + x - 20 + x - 40 = 180

→ x + x + x - 20 - 40 = 180

→ 3x -60 = 180

→ 3x = 180 + 60

→ 3x = 240

→ x = 240/3

→ x = 80

Thus, we got the value of x i.e 80

Subsituting Values :-

Measure of 1st angle = x = 80°
Measure of 2nd angle = x - 20 = 80 - 20 = 60°
Measure of 3rd angle = x - 40 = 80 - 40 = 40°

C. Calculate the compound interest on Rs 20000 for 3 years if the rates ofinterest for the first second and third year are respectively 8%, 9% and10% per annum

Answer»

ANSWER:

Here, PRINCIPAL amount (P)=20000 Rs

So, amount after first YEAR =20000(1+10100)1

Amount after second year =20000(1+10100)(1+10100)1

Amount after third year =20000(1+10100)(1+10100)(1+12100)1

=20000∗1110∗1110∗112100=224∗121=27104 Rs

∴ COMPOUND interest =27104−20000=7104 Rs

Answer the following questions:(i) How many students like only tea?(ii) How many students like only coffee ?(iii) How many students like neither tea or coffee?(iv) How many students like at least one of the beverages?

Answer»

Total number of students who were randomly SELECTED n(S) = 200

Number of students who like tea = 140

Number of students who like coffee = 120

Number of students who like both = 80

So,

Let the number of students who like tea be ' T '

Let the number of students who like coffee be ' C '

So given are :-

n(T)=140

n(C)=120

n(T∩C) =80

Question

(i) How many students like only tea?

Number of students who like only tea = n(T) = 140 students

(ii) How many students like only coffee ?

Number of students who like only coffee = n(C) = 120 students

(iii) How many students like neither tea or coffee?

Number of students who like neither tea or coffee = n(S) - [n(T)+n(C) + n(T∩C)]

$\implies$ 200 - 340 , This is not POSSIBLE so There are no students students like neither tea or coffee

(iv) How many students like at least one of the beverages?
