Answer:

True

Step-by-step explanation:

repeating decimal is also known as recurring decimal. It is form of representation of fractional number in which numbers after decimal periodically gets repeated.

Example 1/9 = 0.1111 where  number one gets repeated infinitely

another common example is 1/7 = 0·142857 142857 14...

here digits 142857 repeated periodically after decimal.

As given in question "A repeating decimal has a never-ending pattern of the same digits" is consistent with definition of repeating decimal hence statement is true.

Answer:

x = a³b + b²/ab + 1

Step-by-step explanation:

x = a² + b²/ab + 1

x = a² × (ab + 1) + b²/ab + 1

x = a³b + a² + b²/ab + 1

x = a³b + b²/ab + 1

Andy Dixon bought 3 paintbrushes for $1.75 each and 7 tubes of oil paint for $2.49 each.how much did he spend in all?
AnnZ [28]
The answer would be $22.68!

If Andy bought 3 paintbrushes for $1.75 each, then we just multiply how much they cost by the number that the bought.

1.75 x 3 = 5.25

If Andy bought 7 tubes of oil paint, we just do the same thing we did in the first step! Multiply how much they cost by the number that the bought.

2.49 x 7 =

Josh buys cucumbers that cost $0.62 per pound.He pays $2.79 for the cucumbers.
Sphinxa [80]
Please refer to the other post you saw.

Josh's estimate IS reasonable because when you have a number 5 or above after the decimal, you round up. Although it's reasonable to round up to 5 pounds, the actual amount is 4.5 pounds, or four and a half.

Answer:

<em>The length of the arc on the sixth swing was </em><em>12.18 ft.</em>

Step-by-step explanation:

A rope is swinging in such a way that the length of the arc traced by a knot at its bottom end is decreasing geometrically.

The third arc is 22 ft. long and the seventh arc is 10 ft.

Hence, the 3rd term is 22 and 7th term is 10.

The length of the arc on the sixth swing is asked, so we have to calculate the 6th term.

We know the nth term in GP is,

T_n=ar^{n-1}

So,

T_3=ar^{3-1}=ar^2  ----------------1

T_7=ar^{7-1}=ar^6  ----------------2

Dividing equation 2 by 1,

\Rightarrow \dfrac{T_7}{T_3}=\dfrac{ar^6}{ar^2}

\Rightarrow \dfrac{10}{22}=\dfrac{ar^6}{ar^2}

\Rightarrow \dfrac{10}{22}=\dfrac{r^6}{r^2}

\Rightarrow \dfrac{r^6}{r^2}=\dfrac{10}{22}

\Rightarrow r^4=\dfrac{10}{22}

\Rightarrow r=\sqrt[4]{\dfrac{10}{22}}

\Rightarrow r=0.8211

Then the 6th term will be,

T_6=ar^{6-1}=ar^5  ----------------3

Dividing equation 2 by 3,

\Rightarrow \dfrac{T_7}{T_6}=\dfrac{ar^6}{ar^5}

\Rightarrow \dfrac{10}{T_6}=\dfrac{a(0.8211)^6}{a(0.8211)^5}

\Rightarrow \dfrac{10}{T_6}=0.8211

\Rightarrow T_6=\dfrac{10}{0.8211}=12.18\ ft

Therefore, the length of the arc on the sixth swing was 12.18 ft.
