Stealth Bank has deposits of $700 million. It holds reserves of $70 million and has purchased government bonds worth $215 millio
zhannawk [14.2K]

Answer:

$75 million

Step-by-step explanation:

Given that:

Reserve value = $70 million

Purchased government bond = 215 million

Market value of loan = $490 million

Net worth :

Assets - liability

Assets = (Market value of loan + purchased government bond + reserve value)

(490 million + 215 million + 70 million)

275 million + 70 million

= $775 million

Liability = Deposits = $700 million

Net worth = ($775 - $700) million

Net worth = $75 million

4/9 expressed as a percent please help and show work! Please
coldgirl [10]
4/9 as a percent is (about) 44%   Work:
First get a decimal by dividing 4/9(4 divided by 9) you get 0.44 repeating
Next, take away the 0. and add a percent sign at the end of 0.44. You get 44%
Truly, the answer is 44.44444...% because the four repeats, but if you round it is simply 44%

Rewrite the following polynomial in standard form. -x -7x^2 -10<br><br> Please Help
DIA [1.3K]

Answer:

-7x^2 - x - 10

Step-by-step explanation:

Rewriting a polynomial in standard form most often involves writing the x terms in descending order by power:  x^2, x^1, x^0

Rewrite -x -7x^2 -10 as -7x^2 - x^1 - 10x^0, which is usually simplified to:

                                       -7x^2 - x - 10

This result is in "standard form."
