The simplified value of [tex]3^4[/tex]/[tex]3^9[/tex] is 1/ [tex]3^5[/tex].
what are exponents and power?Exponent rules, commonly referred to as the "laws of exponents" or "properties of exponents," facilitate the task of simplifying exponent-based statements.
Some laws are
[tex]a^0= 1[/tex][tex]a^m . a^n = a^{m+n[/tex][tex]a^m/ a^n = a^{m-n}[/tex]Given:
3 to the power of 4 divided by 3 to the power of 9
Writing into expression
[tex]3^4[/tex]/[tex]3^9[/tex]
Now, using law of exponents
[tex]a^m/ a^n = a^{m-n}[/tex]
So, [tex]3^4[/tex]/[tex]3^9[/tex]
=[tex]3^{4-9}[/tex]
= [tex]3^{-5[/tex]
=1/ [tex]3^5[/tex]
Hence, the simplified value is 1/ [tex]3^5[/tex].

PLEASE HELP!!! A line y=mx+b passes through point (−4, 6) and is perpendicular to y=−12x+6.
What is the value of b?
Answer:
Improper fraction: 19/3
Mixed number: 6 1/3
Step-by-step explanation:
If these two lines are perpendicular, their slopes are negative reciprocals of each other. The line would be something like:
y = (1/12)x+b
So plug in the coordinate values.
6 = (1/12)(-4)+b
6 = (-1/3)+b
6 1/3 = b

Answer:
4.1 I think
Step-by-step explanation:
I just subtracted in my head
Answer:
4.1 hours
Step-by-step explanation:
Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1

The length of a rectangle is four times its width. Its perimeter is no greater than 170 cm. Find the greatest possible dimensions of the rectangle.
Step-by-step explanation:
let the length be =L
the width is 4 × the length
so the width will be 4L
the formular for the perimeter of a rectangle is =2(L +W)
170=2(L +4L)
170=2(5L)
170=10L
17=L
so the width is 4 × the length
17×4
=68
L=17
W=68

For every left-handed person, there are about 4-right handed people. If there are 30 students in a class, predict the number of students who are right-handed.
Answer:
There are 24 right handed students
Step-by-step explanation:
This is a ratio question so it would be represented as 1:4.
First you would do 1 + 4 which is 5.
Then do 30 ÷ 5 which is 6.
Finally multiply 6 by 4 and 1.
So 6 × 4 × 1 is 24.
So there are 24 students who are right handed.

A local construction site has workers that are digging the foundation of a new building. They
can haul away 20 lbs every 3.4 minutes while working. If they work for a total of 403
minutes, how many grams of dirt have they taken away? Round to a whole number.
Answer:
The workers can take away 1,075,280 grams of dirt in 403 minutes.
Step-by-step explanation:
[tex]\frac{403}{3.4}*20 = 2,370.588[/tex] pounds in 403 minutes
1 pound = 453.592 grams
2,370.588 * 453.592 = 1,075,280 grams
A snowplow has maximum speed of 45 miles per hour on a dry highway. Its maximum speed decreases by 1.6 miles per hour for every inch of snow on the highway. According to this model, at what snow depth will the snow plow be unable to move?
Answer:
28.125
Step-by-step explanation:
If it is going 45mph and every hour it decreases 1.6mph per inch of snow added. so 45 divided by 1.6 is 28.125.
You want a new sound system to go with your new television. If you saved $30 for the sound bar that had a 21% discount. What was the original price of the sound bar before the discount?
Answer:
$142.86
Step-by-step explanation:
In order to know the original price of the sound bar, it is best to write the problem above into a mathematical sentence first.
Given: $30 = the amount you were able to save
21% = the discount (this means that $30 is the 21% discount)
Let x be the original price of the sound bar.
The mathematical sentence is:
$30 is 21%(0.21) of x
x=[tex]\frac{30}{0.21}[/tex]
x= $142.857 or $142.86 (once rounded off to the nearest hundredths)
So, the original price of the sound bar before the discount is $142.86

Out of 60 applicants to a university, 40 are from the East. If 20 applicants are to beselected at random, find the probability that:
a. 10 are from East.
b. Not more than 2 are from East.
Answer:
a. 40С10 * 20С10 / 60С20
b. 1 + (40)(20) + (40C2)(20C2) / 60С20
Step-by-step explanation:
Total number of application = 60
Total number of application from east = 40
Total number of application remaining = 20
Number of ways of selecting 20 applicant = 60C20 (Sample space)
a. Probability of 10 are from East.
= (10 from east) * (10 from remaining)
= 40С10 * 20С10 / 60С20
b. Probability of Not more than 2 are from East.
= P(x≤2)
= P(x=0) + P(X=1) + P(X=2)
= [40С0 * 20С20 / 60С20] + [40С1 * 20С19 / 60С20] + [40С2 * 20С18 / 60С20]
= 1 + (40)(20) + (40C2)(20C2) / 60С20
