Answer:

The general term for the sequence can be given by the following formula:

a_n=2\,n+9

Step-by-step explanation:

If the sequence you typed starts with first term 11 and continues with terms 13, 15, 17, 19, We understand that the sequence is formed by adding 2 units to the previous term. So we are in the case of an arithmetic sequence with constant difference (d) = 2, and with first term 11.

Therefore, the nth term of this arithmetic sequence can be expressed by using the general form for an arithmetic sequence as:

a_n=a_1\,+\,(n-1)\,d\\a_n=11\,+\,(n-1)\,2\\a_n=11+2\,n-2\\a_n=2\,n+9

Answer:

\frac{7}{3} =2\frac{1}{3}

Step-by-step explanation:

For the problem:

\frac{5}{3} +\frac{4}{6} = ?

The Least Common Multiple (LCM) of 3 and 6 is 6. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

\frac{5}{3} +\frac{4}{6} =\frac{5*2}{3*2} +\frac{4}{6} =\frac{10}{6} +\frac{4}{6}

Now that the fractions have like denominators, add the numerators:

\frac{10}{6} +\frac{4}{6} =\frac{10+4}{6} =\frac{14}{6}

The Greatest Common Factor (GCF) of 14 and 6 is 2. The result can be simplified by dividing both the numerator and denominator by 2.

\frac{14}{6} =\frac{14/2}{6/2} =\frac{7}{3}

7 ÷ 3 = 2R1, therefore:

\frac{7}{3} =2\frac{1}{3}

scoray [572]

Answer:

$1545.65.

Step-by-step explanation:

We have been given that Victor has a credit card with an APR of 13.66%, compounded monthly. He currently owes a balance of $1,349.34.

To solve our given problem we will use compound interest formula.

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

A = Final amount after t years,

P = Principal amount,

r = Interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

Let us convert our given interest rate in decimal form. 13.66=\frac{13.66}{100}=0.1366

Upon substituting our given values in compound interest formula we will get,

A=1,349.34(1+\frac{0.1366}{12})^{12*1

A=1,349.34(1+0.011383333)^{12

A=1.349.34(1.011383333)

A=1,349.34*1.145485275522

A=1,545.64910167397 ≈ $1545.65

Therefore, Victor will owe an amount of $1545.65 after one year.

The bakers at Healthy Bakery can make 270 bagels in 10 hours. How many bagels can they bake in 15 hours? What was the rate per h
Tcecarenko [31]

Answer:

405 bagels 27 an hour

Step-by-step explanation:

this is because when you divide 270 by 10 you get 27 which is how much per hour then multiply the # of bagels and the # of hours you get is 405. In other words you first want to know how many bagels it took to get to 270 bagels in 10 hours.Hope it helped.
