what does the equation √3/8
Step-by-step explanation:
The square root of 3 is the positive real number that, when multiplied by itself, gives the number 3. It is denoted mathematically as √3. It is more precisely called the principal square root of 3, to distinguish it from the negative number with the same property. The square root of 3 is an irrational number.

Plz help I don’t understand how to find x?
Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.
$30 before tax
discount 20% tax 6.4%
tip 15%
Answer: $30.44
Step-by-step explanation:
$30 20% of tht is 6
30-6=24
tax is 6.4% which is 1.94
24+1.94 which equals $25.94
tips is 15% 4.5 so we add that to $25.94
so total is $30.44
Answer:
$29.14
Step-by-step explanation:
$30 before tax and discount
20% discount
100% - 20% = 80% = 0.8
0.8 * $30 = $24 after discount before tax and tip
tax: 6.4%
100% + 6.4% = 106.4% = 1.064
1.064 * $24 = $25.54
tip: 15% = 0.15
0.15 * $24 = $3.60
total = $25.54 + $3.60 = $29.14

Answer:
b = 15c = 51c = 100b = 25.75Step-by-step explanation:
Using the Pythagoras theorem equation:
[tex]c^{2}=a^{2}+b^{2}[/tex]
Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.
1) Here c = 17, a = 8 and b = ?
Then, using the above equation we can find the side b.
[tex]17^{2}=8^{2}+b^{2}[/tex]
[tex]b=\sqrt{225}[/tex]
[tex]b=15[/tex]
2) Here a = 24, b = 45 and c = ?
[tex]c=\sqrt{24^{2}+45^{2}}[/tex]
[tex]c=51[/tex]
3) Here a = 28, b = 96 and c = ?
[tex]c=\sqrt{28^{2}+96^{2}}[/tex]
[tex]c=100[/tex]
4) Here a = 17, b = ? and c = 28
[tex]b=\sqrt{28^{2}-11^{2}}[/tex]
[tex]b=25.75[/tex]
Just in the 4 case x is an altitude.

Pedro is an airline attendant. Last week, he worked on flights on 4 small jets and 3 large jets, which could seat a total of 418 passengers. The week before, he was assigned to flights on 5 small jets and 3 large jets, which could seat a total of 464 passengers. How many seats were on each type of flight?
The flights on small jets each had ____seats, and the flights on large jets each had
______seats.
Answer:
Seats on small jet = x = 46 seats
Seats on large jet = y = 78 seats
Step-by-step explanation:
Let
Seats on small jet = x
Seats on large jet = y
4x + 3y = 418 (1)
5x + 3y = 464 (2)
Subtract (1) from (2)
5x - 4x = 464 - 418
x = 46 seats
Substitute x = 46 into (1)
4x + 3y = 418
4(46) + 3y = 418
184 + 3y = 418
3y = 418 - 184
3y = 234
y = 234/3
y = 78 seats
Seats on small jet = x = 46 seats
Seats on large jet = y = 78 seats
The flights on small jets each had 46 seats, and the flights on large jets each had
78 seats.
What does rate of change mean? List 2 to 4 bullets below for BRAINLIEST ANSWER NEEDED ASAP!!!!
Answer: A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Step-by-step explanation: Hope this help
It tells us the average speed. For instance, if you move 10 meters in 4 seconds, then the average rate of change is 10/4 = 2.5 meters per second. This could apply to moving from one location to another.
It could also be used to describe how much work you can get done over time. For example, let's say you paint 5 square meters of a wall per hour. This is the speed at which you get the job done. After 1 hour, you've painted 5 square meters of wall. After 2 hours, you've painted 2*5 = 10 square meters, and so on.
Another example could be how a population is changing. If there are 100 animals at time 5 hours, then the population becomes 200 animals at time 10 hours, then the rate of change is (200-100)/(10-5) = 100/2 = 50 animals per hour. In other words, the population is going up by 50 animals for every hour.
What is the greatest common factor or 20 and 24
The greatest common factor (GCF) of 20 and 24 is 4, by using both methods which are Listing Factors and Prime Factorization.
What is the Prime Factorization method?
Divide the given number by the smallest prime number. In this case, the smallest prime number should divide by the number exactly. Step 2: Again, divide the quotient by the smallest prime number. Step 3: Repeat the process, until the quotient becomes 1.
To find the greatest common factor (GCF) of 20 and 24, we can use the following methods:
Method 1: Listing Factors
List the factors of 20: 1, 2, 4, 5, 10, 20
List the factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Find the largest factor that both numbers share: 4
Therefore, the GCF of 20 and 24 is 4.
Method 2: Prime Factorization
Find the prime factorization of each number: 20 = 2 x 2 x 5, 24 = 2 x 2 x 2 x 3
Identify the common prime factors: 2 x 2 = 4
Therefore, the GCF of 20 and 24 is 4.
Either method shows that the greatest common factor of 20 and 24 is 4.

Answer:
-9 1/4
Step-by-step explanation:
So what I did was that I put it this for which was -((5+3)+(3/4+1/2)
which then you would get -(8+(3/4+1/2)) which gives you -(8+5/4) because you would convert the 1/2 into 2/4 making it to get 5/4. So then you add the -(8+5/4) which gives you -9 1/4.

The width of a rectangle is 30% of its length. what is the area of the rectangle?
Answer:
L x (.3 * L) = Area
Step-by-step explanation:
30% = 0.3 so width = 0.3 times L
area is L x W
The required area of rectangle is 5070 square ft.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
Given that,
The width of a rectangle is 30% of the length.
And the perimeter of the rectangle is 338 ft.
Let the length of the triangle is l,
Since, width is 30%,
Therefore, width = 0.3 l
Perimeter of rectangle = 2(l + b) = 338
2 (l + 0.3l) = 338
2 x 1.3l = 338
l = 130
Width = 0.3 l = 0.3 x 130 = 39
The area of rectangle = length x width = 130 x 39 = 5070
The area of the rectangle is 5070 square ft.

Answer:
[tex]B.\ (-9, -6)[/tex]

Step-by-step explanation:
A relation is represented as:

Where
[tex]x = domain[/tex]

In the given function,
[tex]\{(-9, 1), (-5, 2), (0, 7), (1, 3), (6, -10)\}[/tex]
The domains are [tex]\{-9,-5,0,1,6\}[/tex]
