Please solve question 10

Answer»

Taking LHS and applying R2->R2-2R1 and R3->R3-3R1 you GET X+y x x
3x+2y 2x 0
7x+5y 5x 0
Now expand along c3
X | 3x+2y 2x
7x+5y 5x |
Now solving
X[5x(3x+2y)-2x(7x+5y)]
Solving this equation you get the value x^3

1. A piggy bank full of one rupee and fifty paise coins. It contains 3 times as many fifty paise coins as one rupee coins. the total amount of money in the piggy bank is rupee 45 . how many coins of each kind are there in piggy bank

Answer»

Let fifty paise coins be X
let 1 rupee coins be y
then, 3X = y. ---------------1eq.
x + y = 45 ------------------------2eq.
taking eq. 1 we get
y= 3x
then put y= 3x in eq.2 to get value of x
x + 3x = 45
4x = 45
x = 45/4
put x = 45/4 in eq.1
y = 3 (45/4)
y = 135 /4

5x + 7÷2 = (3÷2)x - 14Can you please solve this equation

Answer»
5x +  \frac{7}{2}  =  \frac{3}{2} x - 14 \\ 5x -  \frac{3}{2} x =  - 14 -  \frac{7}{2}  \\  \frac{10x - 3x}{2}  =  \frac{ - 28 - 7}{2}  \\  \frac{7x}{2}  =  -  \frac{35}{2}  \\ 14x =  - 70 \\ x =   - \frac{70}{14}  =  - 5

We have to find the value of n in this equation.

Answer»

Given,

 2 = 60/N * √n/90

2 = 60√n / 90 n

2 = 2√n / 3 n

2 * 3 n = 2√n

6 n = 2 √n

6 n / 2 =√n

3 n = √n

( 3 n ) ^ 2 = n

9 n^2 = n

9 n ^ 2 / n = 1

9 n = 1

n = 1 / 9

Population projection calculation formula

Answer»

Population projections are simply mathematical formulas that use current populations and RATES of GROWTH to estimate future populations. Many equations are used to project future populations. A basic equation is Nt=P e (r * t). "Nt" represents the number of people at a future TIME. "P" is the population at the beginning time. "e" is the base of the natural LOGARITHMS (2.71828). "r" is the rate of increase (natural increase DIVIDED by 100). "t" represents the time period involved.

Kindly provide me formula for 12*4 is divisible by 4

Answer»

A no. that divides with 4 that no.s last 2 digits must be divisible by 4 such as
1212 is divisible by 4 as 12 is divisible by 4
1124 is duvisible by 4 as 24 is divisible by 4

Similarly
Your question
i.e. 12*4
so just think a LEAST no. or highest no. as GIVEN in question so that *4 is duvisible by 4

By trial and ERROR method we found the ANSWER is 2 or 6 so it can divided by 4

Math define remainder theorem with example

Answer» REMAINDER THEOREM -> Let p(X) be any polynomial of degree greater than or equal to 1
and (x-a) is a LINEAR polynomial , when DIVIDED by (x-a) the remainder is p(a).

Ex. x^2 - 1 ÷ x - 1
p (x) = x^2 -1
the remainder is
p (1) = 1^2 -1
p (1) = 0
NOTE :- We find ZERO of divisor and put the value of variable in dividend to find the remainder.

At t minutes past 2 pm, the time needed by the minute hand of a clock to show 3 pm was found to be 3 min less than t (square) /4 min. Find t

Answer»

Given time needed by the minutes hand show (t2/4) – 3
Hence the quadratic equation BECOMES, (t2/4) – 3 = 60 – t
(t2 – 12)/4 = 60 – t
(t2 – 12) = 240 – 4 t
t2 – 12 – 240 + 4 t = 0
t2 + 4t – 252 = 0
t2 + 18t – 14t – 252 = 0
t(t + 18) – 14(t + 18) = 0
(t + 18)(t – 14) = 0
(t + 18) = 0 or (t – 14) = 0
∴ t = - 18 or t = 14
Since t cannot be negative, t = 14
