Explain why the product is always less than one when you multiply a fraction by another fraction

Because when you do that ...

-- you're starting with a piece that's less than ' 1 ', and

-- you're calculating a piece of it that's less than the whole original piece.

So a proper fraction (one that is less than one like 1/2 and not 5/3) is always less than one
by definition, a fraction means a 'part of' so if you multiply a fraction of a fraction it is like finding a part of a part and if the origonal part was less than one, then the result will be less than one like

1/2 of 2/4= (2/4=1/4+1/4) so 1/2 of 2/4=1/4 which is less than one

suppose a laser beam directed toward the visible center of the moon misses its assign target by 30 seconds . How far in miles fr

oksian1 [2.3K]

Answer:

<u><em>Approximately 600 miles</em></u>

Explanation:

There are several ways to solve this using different assumptions.

First you need to imagine an isosceles triangle formed by:

the equal sides of the triangle are the distance between the Earth and the Moon: 234,000 miles

the included angle is 30 second of degree

the base side of the triangle, opposed to the 30 seconds angle, is how far in miles from its assigned target the laser beam is: x

You can solve for x in several ways.

I will use the cosine rule:

$c^2=a^2+b^2-2accos(\alpha)$

Where:

$c=x\\\\a=234,000miles\\\\b=234,000miles\\\\\alpha=30seconds$

One second of degree equals 1/3600 degrees:

$30seconds\times 1degree/3600seconds=1/120degrees$

Substitute in the equation and compute:

$x^2=(234,000miles)^2+(234,000miles)^2-2(234,000miles)(234,000miles)\times cos(1/120\º)$

$x=579.15mile\approx600miles$

Solve the equation -10x + 1 + 7 = 37

Aneli [31]

Answer:

-2.9

Step-by-step explanation:

-10x + 1 + 7 = 37

Combine like factors.

-10x + 8 = 37

Subtract 8 from both sides.

-10x = 29

Divide both sides by -10.

x = -2.9

Confused, what am I supoosed to be doing here? x+10=18

Vanyuwa [196]

<u><em>Answer: x=8</em></u>

Step-by-step explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

subtract by 10 from both sides of an equation.

x+10-10=18-10

simplify

18-10=8

<u><em>x=8</em></u>

Hope this helps!

Thanks!

Have a great day!
