Answer:

3.8 = 38/10 = 19/5

Step-by-step explanation:

You can always represent a terminating decimal number as the ratio of integers. Count the number of decimal places, and multiply and divide it by 10 to that power. If you like, you can reduce the resulting fraction. 3.8 has 1 decimal place, so our chosen power of 10 is 10¹.

3.8 = (3.8×10¹)/(10¹) = 38/10 = 19/5

A maritime flag is shown. What is the area of the shaded part of the flag? Explain

Rom4ik [11]

Answer:

<em></em> $Area = 72in^2$ <em></em>

<em></em>

Step-by-step explanation:

<em>Your question is incomplete without an attachment (See attachment)</em>

Required

Determine the area of the shaded part

From the attachment;

<em>Assume that the shaded portion is closed to the right;</em>

<em>Calculate the Area:</em>

<em></em> $Area_1 = Length * Width$ <em></em>

<em></em> $Area_2 = 8in * (6in + 6in)$ <em></em>

<em></em> $Area_2 = 8in * 12in$ <em></em>

<em></em> $Area_1 = 96in^2$ <em></em>

<em></em>

<em>Next;</em>

<em>Calculate the Area of the imaginary triangle (on the right)</em>

<em></em> $Area_2 = \frac{1}{2} * base * height$ <em></em>

<em></em> $Area_2 = \frac{1}{2} * (6in + 6in) * 4in$ <em></em>

<em></em> $Area_2 = \frac{1}{2} * 12in * 4in$ <em></em>

<em></em> $Area_2 = \frac{1}{2} * 48in^2$ <em></em>

<em></em> $Area_2 = 24in^2$ <em></em>

<em></em>

<em>Lastly, calculate the Area of the Shaded Part</em>

<em></em> $Area = Area_1 - Area_2$ <em></em>

<em></em> $Area = 96in^2 - 24in^2$ <em></em>

<em></em> $Area = 72in^2$ <em></em>

<em></em>

<em>Hence,</em>

<em>The area of the shaded part is 72in²</em>

At Brunswick Elementary school, 2/5 of six-grade students have at least one pet. If school has 181 sixth graders, about how many

VashaNatasha [74]

Answer: 72.4

Step-by-step explanation:

Fraction of six-grade students that have at least one pet = 2/5

Number of sixth graders at Brunswick Elementary school = 181

The number of sixth graders that own own pets will be:

= 2/5 × 181

= 72.4
