Rate (R) = 25/3<br>Interest = Rs. 350<br>(d) Principal = Rs. 2400<br><br>Find the time (t) ​
julia-pushkina [17]

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

i =  \frac{prt}{100}

let \: i = 350,p = 2400,r =  \frac{25}{3}

350 =  \frac{2400 \times  \frac{25}{3} \times t }{100}

350 =  \frac{20000t}{100}

350 \times 100 = 20000t

20000t = 35000

t = 35000 \div 20000

t = 35 \div 20

t = 1.75 \: years

Solve (u+6)^2+4=52 , where u is a real number.
Ugo [173]

Answer:

The value of u are,

0.93, -12.93

Step-by-step explanation:

It is given an expression in variable u

(u + 6² + 4 = 52

<u>To find the solution of given expression</u>

(u + 6)·² + 4 = 52

(u + 6)²  = 52 - 4

(u + 6)² = 48

u + 6 = √48

u + 6 = ±6.93

u =  ±6.93 - 6

u = 6.93 - 6  or u = -6.93 - 6

u = 0.93 or u = -12.93

Please help me :'( I have been stuck on this
madam [21]

This is really weird.

-- NONE of the situations matches the equation at the top. 

-- And the equation at the top isn't even really any big deal . . .
it's <em>always</em> true, no matter what  ' t '  is .  If you remove all of
the parentheses and simplify it, it says that  6 = 6.  Well duh !
