Answer:

42300000

Step-by-step explanation:

Use known fact

$1\ km=1000\ m$

Consider 1 square kilometer:

$1\ km^2=1\ km\times 1\ km=1000\ m\times 1000\ m=1000000\ m^2$

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

$42.3\ km^2=42.3\times 1000000\ m^2=42300000\ m^2$

A certain star is 2.4 x 102 light years from the Earth. One light year is about 5.9 x 1012 miles. How far

Studentka2010 [4]

Answer:

2.5 x $10^{15}$ miles

Step-by-step explanation:

We are given that 1 light year ≈ 5.9 x $10^{12}$ miles so:

4.3 x 10² light year · <u>5.9 x </u> $10^{12}$ <u> miles </u>
1 light year

Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:

≈25 x $10^{14}$

This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:

≈ 2.5 x $10^{15}$ miles

Answer ASAP In the given diagram, ∠4 = 45°, ∠5 = 135° and ∠10 = ∠11 Part A: Solve for the values of the remaining angles. Show a

MaRussiya [10]

Answer:

A) ∠9 = ∠10 = ∠11 = ∠12 = 90°

∠2 = ∠3 = ∠5 = ∠8 = 135°

∠1 = ∠4 = ∠6 = ∠7 = 45°

B) 1. ∠4 and ∠1 -> vertical angles

2. ∠7 and ∠5 -> supplementary

3. ∠9 and ∠10 -> supplementary

Step-by-step explanation:

<u>Data</u>

∠4 = 45°

∠5 = 135°

∠10 = ∠11

The following are vertical angles, so they are congruent:

∠1 ≅ ∠4

∠3 ≅ ∠2

∠11 ≅ ∠9

∠10 ≅ ∠12

∠7 ≅ ∠6

∠5 ≅ ∠8

From here and data, it is deduced that

∠11 ≅ ∠9 ≅ ∠10 ≅ ∠12

From the picture, the addition of them is equal to 360°, then:

∠11 + ∠9 + ∠10 + ∠12 = 360°

4*∠11 = 360°

∠11 = 360°/4

∠11 = 90° = ∠10 = ∠9 = ∠12

∠2 and ∠4 are supplementary, then:

∠2 + ∠4 = 180°

∠2 = 180° - 45°

∠2 = 135°

∠7 and ∠5 are supplementary, then:

∠7 + ∠5 = 180°

∠7 = 180° - 135°

∠7 = 45°

A regular octagon has an apothem measuring 10 in, and a

jeyben [28]

<em>Answer:</em>

<em>332 square inch</em>

<em>Step-by-step explanation:</em>

<em>Solving for an area of a regular octagon, we can make use of the formula shown below: </em>

<em> </em>

<em>Area = 1/2 * apothem*perimeter </em>

<em> </em>

<em>In this problem, the following values were given such as: </em>

<em>Apothem = 10 inches </em>

<em>Perimeter = 66.3 inches </em>

<em> </em>

<em>Solving for the area: </em>

<em>Area = 1/2*10*66.3 </em>

<em>Area = 331.5 inches² </em>

<em> </em>

<em>The answer is 332.</em>
