1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is th

Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

$I=Prt$

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

$I=Pr(3)\\$

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

$I=\frac{Pr(4)}{12}$

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

$I=\frac{Pr(45)}{365}$

P + nx=rx-e (solve for x)

lorasvet [3.4K]

Answer:

(p+e)/(r-n) = x

Step-by-step explanation:

p + nx=rx-e

Add e to each side

p +e+ nx=rx-e+e

p +e+ nx=rx

Subtract nx from each side

p +e+ nx - nx=rx-nx

p+e = rx -nx

Factor out x

p+e = x(r-n)

Divide each side by (r-n)

(p+e)/(r-n) = x(r-n)/(r-n)

(p+e)/(r-n) = x

A square has a side length of 10cm. Work out the length of a diagonal of the square.

Vitek1552 [10]

Answer: Let x = the length of a side of the square

a2 + b2 = c2

x2 + x2 = 102

2x2 = 100

x2 = 50

x = √50

x = 5√2 cm

Between July 28 and 30 of last year over 41.2 cm (about 16 inches) of rain fell in a city. The normal total monthly rainfall i

ZanzabumX [31]

The amount more of rain that fell in those three days than normally falls in July and August combined was 31.19 cm.

<h3>How much more rain fell in those three days?</h3>

The amount of rain in those three days was 41.2 cm.

The combined normal rain July and August is:

= 6.36 + 3.65

= 10.01 cm

The difference is therefore:

= 41.2 - 10.01

= 31.19 cm
