What is the simplified value of this expression pls help

tester [92]

Answer:

Step-by-step explanation:

Remove parentheses.

$\frac{-8+4(4.5)}{6.25-8.25} \\$

Add −8 and 4.5.

$\frac{4(-3.5)}{6.25 - 8.25} \\\\$

Subtract 8.25 from 6.25.

$\frac{4*-3.5}{-2}$

Multiply 4 by −3.5.

$\frac{-14}{-2}$

Divide −14 by −2.

Orlando invests S1000 at 6% annual interest compounded daily and Bernadette invests S1000 at 170

Ainat [17]

Answer:

So it will only take a year for Orlando's investments be worth more than

Bernadette's investments

Step-by-step explanation:

Interest of Bernadette in a year

=( 1000*170*1)/100

= 1700

So amount at a year is$ 2700

For Orlando amount the end of the year with compound interest daily.

A = P(1+r/n)^nt

A = 1000(1+(17/365))^(365*1)

A = 1000(1+0.0466)^365

A = 1000(1.0466)^365

A= $1.659*10^10

So it will only take a year for Orlando's investments be worth more than

Bernadette's investments
