I am assuming that you are supposed to answer this division problem through the long division method. So my answer is going to be a step-by-step description of the long division solution for this problem.

The first step is to move the decimal point of the dividend and the divisor. Hence, 1264.0 and 17. The decimal point of the quotient shall then be written in alignment with the decimal point of the dividend.

Then we proceed with the division process, 126/17 gives us 7 (write this above the division bar). 7 multiplied by 17 gives 119 (write this under the divisor). So 126-119 is equal to 7. We then bring down the digit after 126 of the divisor, which is 4. So we now have 74. 74 divided by 17, we get 4. 4 multiplied by 17 gives 68. We subtract 68 from 74 and we have 6, bring down 0, we have 60. We then repeat the division-multiplication-subtraction process until we get to the third decimal place of the quotient.

Finally, the answer is 74.352.

Answer: Our required value to three decimal places is 74.352.

Step-by-step explanation:

Since we have given that

126.4 ÷ 1.7

First we rewrite the above numbers :

\dfrac{1264}{10}\div \dfrac{17}{10}

Now, we will solve this:

\dfrac{\dfrac{1264}{10}}{\dfrac{17}{10}}\\\\=\dfrac{1264}{17}\\\\=74.352

Hence, our required value to three decimal places is 74.352.

Seth has a bank account which pays 1.01% interest, compounded quarterly. Seth withdraws $4,567 from the account every quarter fo
dimulka [17.4K]

Answer:

C. $538,021.66

Step-by-step explanation:

It is given that the money Seth withdraws was compounded every quarter for 35 years. So, we get,

Amount withdrawn every quarter, P = $4567

Rate of interest, r  = \frac{0.0101}{4} = 0.002525

Time period, n = 35 × 4 = 140

Now, as we know the formula for annuity as,

P=\frac{r \times PV}{1-(1+r)^{-n}}

where P = installments, PV = present value, r = rate of interest and n = time period.

This gives, PV=\frac{P \times [1-(1+r)^{-n}]}{r}

i.e. PV=\frac{4567 \times [1-(1+0.002525)^{-140}]}{0.002525}

i.e. PV=\frac{4567 \times [1-(1.002525)^{-140}]}{0.002525}

i.e. PV=\frac{4567 \times [1-0.7021]}{0.002525}

i.e. PV=\frac{4567 \times 0.2975}{0.002525}

i.e. PV=\frac{1358.68}{0.002525}

i.e. PV=538,091.08

So, the closest answer to initial value of the account is $538,021.66

Hence, option C is correct.

Which of the following gives a valid reason for using the given solution method to solve the system of equations shown? Equation
alukav5142 [94]

Answer:

* Elimination; a coefficient in Equation I is an integer multiple of a coefficient in Equation II.

* Elimination; a coefficient in Equation II is an integer multiple of a coefficient in Equation I.

Step-by-step explanation:

Equation I: 4x − 5y = 4

Equation II: 2x + 3y = 2

These equation can only be solved by Elimination method

Where to Eliminate x :

We Multiply Equation I by a coefficient of x in Equation II and Equation II by the coefficient of x in Equation I

Hence:

Equation I: 4x − 5y = 4 × 2

Equation II: 2x + 3y = 2 × 4

8x - 10y = 20

8x +12y = 6

Therefore, the valid reason using the given solution method to solve the system of equations shown is:

* Elimination; a coefficient in Equation I is an integer multiple of a coefficient in Equation II.

* Elimination; a coefficient in Equation II is an integer multiple of a coefficient in Equation I.

A circle's diameter is 4 feet.
Soloha48 [4]

Answer:

13

Step-by-step explanation:

The formula for cirmference is

C= π2 * r

we're using 3.14 as pi and r = radius.

the radius is always half of the diameter.

So in this case since the diamter is 4, the radius is 2. let's substitute these numbers.

C= 3.14 *2*2 and there your answer is 12.56 which rounded to the nearest tenth is 13.

Hope this helps :)
