Square root of 129 is greater than, less than or equal to 95/8?​
Tanzania [10]

√129 is less than \frac{95}{8}.

\large\mathfrak{{\pmb{\underline{\purple{Step-by-step\:explanation}}{\purple{:}}}}}

Let us first solve for √129.

➝\:\sqrt{129}

➝\:11.3578

Now,

➝\: \frac{95}{8}

➝\:11.875

Clearly,

➵\:11.3578 < 11.875

➵\: \sqrt{129}  <  \frac{95}{8}

Hence, √129 is less than \frac{95}{8}.

Use lengths |OQ| = 9.4 units and |OQ’| = 17.1 units to determine the scale factor r of dilation D (round to the nearest hundredt
NNADVOKAT [17]

Answer:

Scale factor = 1.82 units.

Step-by-step explanation:

We have been given that side length OQ of our prei-mage is 9.4 units and side length OQ' after dilation is 17.1 units. Since our pre-image (original image) is smaller than our new image, so our scale factor (r) will be greater than 1.

Since we know that in a dilation, the sides of the pre-image and the corresponding sides of the image are proportional, so we will use proportion to find a scale factor our given side lengths as:

\frac{OQ'}{OQ}=\frac{17.1}{9.4}

\frac{OQ'}{OQ}=1.8191

Upon multiplying both sides of our equation by OQ we will get,

\frac{OQ'}{OQ}\times OQ=1.8191\times OQ

OQ'=1.8191\times OQ

Upon rounding our answer to nearest hundredths place we will get,

OQ'\approx 1.82\times OQ

Since side length OQ' is 1.82 times side length OQ, therefore, our scale factor (r) will be 1.82 units.

The growth rate of nominal gdp between 1998 9063 <br> and 2018 20501 was
Alex73 [517]

Answer:

The nominal GDP growth rate between 1998 and 2018 was 126.20 percent.

Step-by-step explanation:

Given that in 1998 the country's GDP was $ 9,063 and in 2018 it was $ 20,501, to determine the nominal growth rate of the nation's GDP, the following calculation must be made:

9,063 = 100

20,501 = X

((20,501 x 100) / 9,063) = X

2,050,100 / 9,063 = X

226.20 = X

226.20 - 100 = 126.20

Therefore, the nominal GDP growth rate between 1998 and 2018 was 126.20 percent.
