Answer:

<em>-9.7 + 18.6</em>

Step-by-step explanation:

Given the expression:

-9.7 - (-18,6)

The additive inverse of -18.6 is 18.6

The product of teo negative sign will also give a positive sign, hence:

-9.7 - (-18,6) = -9.7 + 18,6

-9.7 + 18,6 = 18.6 - 9.7

18.6 - 9.7 = 8.9

<em>Hence the expression can also be written as -9.7 + 18.6 with 8.9 being the solution</em>

The simple interest earned on a deposit of 4000 at 5% for 120 days
Ymorist [56]

Answer:A = $4,066.00

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Putting time into years for simplicity,

120 days / 360 days/year = 0.33 years.

Solving our equation:

A = 4000(1 + (0.05 × 0.33)) = 4066

A = $4,066.00

The total amount accrued, principal plus interest, from simple interest on a principal of $4,000.00 at a rate of 5% per year for 0.33 years (120 days) is $4,066.00.

* Hopefully this helps:) Mark me the brainlliest:)!!

Step-by-step explanation:

\cos{A}=\cos{\frac{x}{2}}=\pm\sqrt{\dfrac{1+\cos{x}}{2}}

Apparently, you're supposed to recognize that the formula tells you the value of cos(x/2).

Aleksandr-060686 [28]

Answer:

13

Step-by-step explanation:

I think the turtle would be 13 and 1/3 because we know that the turtle is half as old as the parrot. So if we divide 10 by 3/4 we can get how old the turtle is now
