The total is 60.

To solve this question, I used proportions. First, I set up two ratios (18:__ is equal to 30:100). I multiplied 18 by 100 to get 1800, and then divided 1800 by 30 to get my final answer of 60.

Factor the polynomial: – x3 - 4x2 - 5x

Alinara [238K]

Answer:

$-x3-4x2-5x=-x(x^2+4x+5)$

Step-by-step explanation:

we are given the polynomial as

$-x3-4x2-5x$

here we can see that the GCF of $-x^3$ , $-4x^2$ and $-5x$ is

$-x$

Hence we take it outside the bracket

$-x(x^2+4x+5)$

The polynomial within the bracket $x^2+4x+5$ can not be factorized further , hence this would be our final answer.

How much would you need to deposit in an account now in order to have $4000 in the account in 10 years? Assume the account earns

gogolik [260]

Answer:

$2355.06

Step-by-step explanation:

Use the compound interest formula, filling in the numbers you know. Then solve for the number you don't know.

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

where A is the account balance, P is the amount invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

Filling in the given values, we have ...

4000 = P(1 +.053/52)^(52·10) = P(1.6984738)

P = 4000/1.6984738 ≈ 2355.06

You would need to deposit $2355.06 in order to have $4000 in 10 years.

At a store, a shirt was marked down in price by $10.00. A pair of pants doubled in price. Following these changes, the price of

Galina-37 [17]

The required new price of the shirts and pair of paints is given as y = [s - 10]/2 and y = [2p]/2 respectively,

Given that,
At a store, a shirt was marked down in price by $10.00. A pair of pants doubled in price. Following these changes, the price of every item in the store was cut in half.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
let y be the total cost for each different item
cost of the shirt = s - 10 and pair of pants = 2p
According to the question,
y = s - 10 / 2 and y = 2p / 2

Thus, the required new price of the shirts and pair of paints is given as y = [s - 10]/2 and y = [2p]/2 respectively,
