(10x2 + 99x – 5) ÷ (x + 10) =

Rasek [7]3 years ago

The answer to this problem is 10x - 1 with a 5 reminder, which can also be written as 10x - 1 + 5/(x + 10).

To find this, we first have to turn it into a long division problem. First we look to see how many times x goes into 10x^2.

10x^2/x = 10x.

Now we eliminate the first term and multiply the 10x by the second term.

10x * 10 = 100x.

We now subtract that 100x from 99x. This gives us a -x remainder. We can now see how many times x goes into that as well.

-x/x = -1

This gives us the final answer of 10x - 1 with a 5 remainder.

Answer:

x=12

Step-by-step explanation:

Since the angle needs to add up to 90, you will first need to subtract 30 from 90. This will leave you with 60. Next you will divide 60 by 5 which will give you 12 which is the answer.

Answer:

The radius of cylinder is 14 inches

Step-by-step explanation:

Given that the volume of cylinder is 196π in² and the height is 1 in . The formula for it is V = πr²h. Then you can substitute the following value into the formula:

V = 196π

h = 1

196π = π × r² × 1

r² = 196π/π

r² = 196

r = 14 in

The formula used to calculate the value of a savings accounty =(1+)120What does theafter t years is A(t)=0.04= 1500 1+120.04frac
yulyashka [42]

We have here the formula for Compound Interest:

A=P(1+\frac{r}{n})^{nt}

Where:

• A is the accrued amount.

,

• P is the Principal (the original amount of money, the starting amount of money).

,

• r is the interest rate.

,

• n is the number of times per year compounded.

,

• t is the time in years.

When we have that n is equal to 12, we are talking here about that the amount of money is being compounded monthly (we have 12 months in a year, 12 periods, n = 12). <em>Therefore, we are dividing the rate, r, by the number of compoundings per year, n, and this is the rate per each new compounding period of time, r/n, and, in this case, n = 12 (monthly interest rate). </em>

Therefore, in few words, the fraction (0.04/12) is the monthly interest rate (option C).

[If we see the other options, we have:

• The daily interest rate would be given by 0.04/365.

,

• How long the money has been in the account is time, t.

,

• The starting balance in the account is the Principal, P. ]
