Answer:

see attached

Step-by-step explanation:

When the sequence of sides (shortest to longest, for example) remains the same (CW or CCW), then the number of reflections is even, possibly zero. The figure will have been translated if all of the corresponding sides retain their original direction, otherwise rotation is involved.

If the sequence is reversed, as in the upper right and lower left figures, then reflection is involved. The line of reflection will be the line through the midpoints of the segments connecting corresponding vertices.

Complete the following sentence with a power of ten greater than 1. A kilometer is times as large as a millimeter. Click on the

Gelneren [198K]

Answer:

A kilometer is 10⁶ times as large as a millimeter.

Step-by-step explanation:

In the metric system first we have: millimeter, centimeter, decimeter and meter. Each one of these is 10 times the other (1 centimeter is 10 millimeter, 1 decimeter is 10 centimeter, 1 meter is 10 decimeter). Therefore, 1 meter is 10x10x10 millimeter = 1 meter is 1000 millimeters.

But we know that 1 km is 1000 meters,

Therefore, 1 km = 1000 meter = 1, 000,000 milimeter = 10⁶ milimeter

So then, we have that 1 kilometer is 10⁶ as large as a milimeter.

Compare the doubling times found with the approximate and exact doubling time formulas. Then use the exact doubling time formula

g100num [7]

The population after 15 years become according to the doubling time is 470000000.

According to the statement

We have given that the nation of 200 million people is growing at a rate of 9% per year.And we have to find that the What will its population be in 15 years.

So, For this purpose, we know that the

The doubling time is the time it takes for a population to double in size/value. It is applied to population growth etc.

So,

Population of nation is 200 million and growing at a rate of 9% per year.

So, 9% of the population is

Percentage population = 9/100*200,000,000

Percentage population = 9* 200,000,0

Percentage population = 1800,000,0.

It means 18000000 number of population is increased per year.

So, The total population increased in 15 years is 15*18000000

The total population increased in 15 years is 270000000.

The population after 15 years is 270000000 + 200,000,000

The population after 15 years is 470000000.

So, The population after 15 years become according to the doubling time is 470000000.

What is the area of a rectangle if 1 base is 14 in, the 2nd base is 3.5 in and the height is 8 in?

algol13

Check the picture below.

notice, we have three pair of sides, let's add them all up to get the area

$\stackrel{\textit{left and right}}{2(8\cdot 14)}+\stackrel{\textit{front and back}}{2(3.5\cdot 8)}+\stackrel{\textit{top and bottom}}{2(3.5\cdot 14)}\implies 378~in^2$

Continuation of the other six questions find the value of eggs and tangent

n200080 [17]

Answer:

Step-by-step explanation:

1) ?

I can't see what that one given angle is .. but it's that mystery angle subtracted from 180 give the angle BOA then you know that's an isosceles triangle again that the BOA is part of... so then just subtract BOA from 180 to find the two other angle of that triangle... they are the small so just divide your answer of 180-BOA /2 is the angle of each.. then since you know those to smaller angles subtract one from 90 to find the angle BAX

2) ( as we would read normally)

You're making this really tough on me.. I can just barely read the equations

I think it's 1+6x and 7x-3 . b/c they are the same length sides you can set those equal

1+6x = 7x -3

4+6x = 7x

4 = x

that worked out well :

for the tangent.. it's Tan(Ф)= Opp/ Adj

but I don't know which side they want to solve for.. I think you may have left off some of the instructions???? :/

ohh I think they really mean.. what's the length of the tangent lines .. that was confusing to me.. :/ just plug in 4 into x for either eq.

1+6(4) = 25

7(4)-3=25

tangent is 25

x-2 = 2x-10

x+8 = 2x

8 = x

again they made it work out easy :)

Then plug 8 into either equation to find the length of the tangent lines

8-2=10

tangent is 10

4) = 2) ??? they are the same question maybe you meant to put something else?
