The living room size on the blue print is 6 inches and the actual size is 10 feet. What is the scale factor?
Directions:
-write # inches = # feet
-be sure to simplify
Answer:The scale factor is 20.
Step-by-step explanation:
6 INCHES = 1/2 FOOT
10 FOOT TO 1/2 FOOT = 10/(1/2) = 20/1
The scale factor is 20 to 1
or, since your scale is 6 in to 10 ft
you may list the scale factor as 1 to 20

The scale factor is 20 .
To understand more, check below explanation.
Scale factor:Given that,
Size of the room on blue print = 6 inches
Actual size of the room = 10 feet
As we know that,
1 feet = 12 inches
6 inches = 1/2 feet
We have to find scale factor from 1/2 feet to 10 feet.
[tex]\frac{10}{1/2}=\frac{10*2}{1} =20[/tex]
Hence, the scale factor is 20 .

Why does it feel cooler at 90°F when the relative humidity is 30% compared to the same temperature and the relative humidity is 80%?
Because the drier air evaporates moisture off your skin more easily.
Because the lower humidity brings down the temperature.
There is no real difference because the temperature is the same.
Because there is less air movement at 80% humidity.

Which two numbers on the number line have an absolute value of 2.75? Select the location of both numbers on the number line.
the answers are: 2.75 and -2.75
absolute value is just the distance from zero on a number line
The required numbers on the number line that have an absolute value of 2.75 are 2.75 and -2.75.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
here,
Absolute values are the values that defined the distance of a number on the number line from 0. So for absolute value 2.75 we have numbers 2.75 and -2.75 both have the same distance from 0.
Thus, the required numbers on the number line that have an absolute value of 2.75 are 2.75 and -2.75.

A closed container has 3.06 ⋅ 10^23 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10^−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
0.47 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10−24) = 4.73 ⋅ 10−1
0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10-24) = 5.1102 ⋅ 10-1
4.73 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10−24) = 4.73
5.11 grams, because (3.06 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 5.1102

Can anyone help find the angles of 4 and 7
Answer:
angles 1 and 3 are 30
angles 5, 8, 10 and 12 are all 85
angle 11 is 95
angles 9 and 6 are 30
7 and 4 are 65
Step-by-step explanation:
angle 2 is congruent to 150, so 1 and 3 are: 360 degrees -150-150=x/2 to get the angles, then cos its an isosceles triangle due to the parallel lines, 9 and 6 are congruent to 1 and three, and 11 is 95 so you do 360 degrees-95-95=x/2 to get 85, then you take the 95 that is congruent to the angle group below it, and subtract 30 cos angles 9 and 4 are equivalent to the whole angle of 11, so yea u subtract 30 and you get 65, and you match up the congruent ones lol hope this helps ik its confusing

a³x - x⁴ + a²x² - ax³
Answer:
[tex]\huge\boxed{x(a-x)(a+x)^2}[/tex]
Step-by-step explanation:
In order to factor this expression, our goal is to write the expression in a way that we can factor out a term.
With the expression [tex]a^3 x - x^4 + a^2 x^2 - ax^3[/tex], we need to note an exponent rule.
[tex]a^{b+c} = a^b a^c[/tex]
Step 1:We can use this to get each term of this expression to have a term of [tex]x[/tex] so we can factor it out.
Let's look at each term and get it so that we can factor out an x term.
[tex]a^3 x = x a^3[/tex] (Commutative Property)[tex]x^4 = xx^3[/tex] (Since [tex]x^3 \cdot x^1 = x^4[/tex])[tex]a^2 x^2 = a^2 \cdot xx[/tex] (Since [tex]x^2 = x \cdot x[/tex])[tex]ax^3 = a \cdot xx^2[/tex] (Since [tex]x^3 = x^2 \cdot x^1[/tex]With this, our equation becomes [tex](xa^3) - (xx^3) + (xxa^2) - (xx^2a)[/tex].
We now can factor out the common term x.
[tex]x(a^3 - x^3 + xa^2 - x^2a)[/tex]
Step 2:From here, we can now factor [tex]a^3 - x^3 + xa^2 - x^2 a[/tex]
Rearrange the equation: [tex]a^3 +xa^2 - x^3 - x^2a[/tex] Factor out [tex]a^2[/tex] from [tex]a^3 + xa^2[/tex] which comes out to be [tex]a^2(a+x)[/tex] Factor out [tex]-x^2[/tex] from [tex]-x^3 - x^2a[/tex] which comes out to be [tex]-x^2(x+a)[/tex] We now have [tex]a^2(a+x) - x^2(x+a)[/tex] Factor out the common term, [tex](a+x)[/tex], which comes out to be [tex](a+x)(a^2 - x^2)[/tex] Factor [tex]-x^2+a^2[/tex] into [tex](a+x)(a-x)[/tex] We now have [tex](a+x) (a+x) (a-x)[/tex], which is simplified to [tex](a-x)(a+x)^2[/tex] Finalizing:Since we have just factored [tex]a^3 - x^3 + xa^2 - x^2 a[/tex] and factored x out of [tex]a^3 x - x^4 + a^2 x^2 - ax^3[/tex] in the first couple of steps, we need to have it as a factorization of x.
[tex]x(a-x)(a+x)^2[/tex]

.Is the following proportion true? How do you know?
4/5 = 25/40
Answer:
4/ 5
is greater than
25 /40
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 5 and 40 is 40
For the 1st fraction, since 5 × 8 = 40,
4/ 5 = 4 × 8 5 × 8 = 32/ 40
Likewise, for the 2nd fraction, since 40 × 1 = 40,
25 /40 = 25 × 1 40 × 1 = 25/ 40
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
32 /40 > 25 /40 or 4 /5 > 25 /40
Answer:
It is not true because if you multiply the denominator by 8, you will get 40 and if you also multiply the numerator by 8, you get 32 which is 32/40 which is not equal to 25/40.
