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 :

$i = \frac{prt}{100}$

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

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

$350 = \frac{20000t}{100}$

$350 \times 100 = 20000t$

$20000t = 35000$

$t = 35000 \div 20000$

$t = 35 \div 20$

$t = 1.75 \: years$

nydimaria [60]

Answer:

41 2/3 feet

Step-by-step explanation:

The sum of wall lengths (in feet) is ...

(12 1/4) + (10) + (12 1/4) + (10 -2 5/6)

= (12 + 10 + 12 + 8) + (1/4 + 1/4 - 5/6)

= 42 + (3/12 + 3/12 -10/12)

= 42 - 4/12 = 42 - 1/3

= 41 2/3 . . . feet
