Step-by-step explanation: The Pythagorean theorem states that, in a right triangle, the length of the hypotenuse squared equals the sum of the squares of the other two sides or legs of the triangle. Algebraically, a2+b2=c2. In your example, the length of the ladder would be the hypotenuse and the distance from the wall would be one of the legs. So substitute these values into the equation to get: 32+b2=122 or 9+b2=144 and then subtract 9 from both sides to get b2=135. Therefore b=√135≈11.62. If your problem requires an exact answer in its most simplified form, please note that √135=3√15. Hope this helps you

Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

Please answer!! What's the slope?
Answer:
B.) undefined
Step-by-step explanation:
It is a vertical line therefore is undefined because
a horizontial line is a line with zero slopea diagnal line from the left bottom to the right top { / } is a line with a positive slopea diagonal line from the left top to the right bottom { \ } is a line with a Negitive slope.Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10
Answer:
5x - 3x = 10
2(2x - 1) = 46
6x - 15 = 75
x+(x - 10) = 26
Step-by-step explanation:
5x - 3x = 10
2x = 10 Divide by 2
x=5
2(2x - 1) = 46 Distribute the 2
4x - 2 = 46 Add 2
4x = 48 Subtract by 4
x = 12
6x - 15 = 75 Add 15
6x = 90 Divide by 6
x=15
x + x - 10 =26 Add the x's together and the 10

may someone please help me understand something in class? its theoretical and experimental probability basically just probability in a whole and I can’t understand. I don’t need the definition I just want someone to make me understand in a simple way like a tutor, but anyways please help me understand this. Examples would work, anything. Just help me understand. Thanks anyways.
Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.
How much would someone pay in property taxes if they live in a $329,000 home in the same area?
Answer:
$26320
Step-by-step explanation:
Percentage solution with steps:
Step 1: We make the assumption that 172000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 172000.
Step 4: In the same vein, x% = 13760
Step 5: This gives us a pair of simple equations:
100% = 172000(1).
x% = 13760(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left-hand side) of both equations have the same unit (%); we have
100% / x% = 172000 / 13760
Step 7: Taking the inverse (or reciprocal) of both sides sides
x% / 100% = 13760 / 172000
=> x = 8%
Therefore, 13760 is 8% of 172000.
Now, I would multiply 329,000 by 8%(or 0.08) to get the answer 26320
Hope this helps!

He pays in property taxes $26320 if they live in a $329,000 home in the same area.
We have the following information available from the question is:
The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.
We have to find the how much would someone pay in property taxes?
Lets assume that:
The home worth cost is $172,000 is 100%
Let the property taxes be x
So, We equal to the value are:
$172,000 = 100%
Similarly, x% = $13,760
This gives us a pair of simple equations:
100% = $172000___(1).
x% = $13760___(2).
By simply dividing equation 1 by equation 2, we get:
100% / x% = 172000 / 13760
Taking the inverse (or reciprocal) of both sides sides
x% / 100% = 13760 / 172000
=> x = 8%
Therefore, 13760 is 8% of 172000.
They live in a $329,000 home in the same area, So
Multiply 329,000 by 8%(or 0.08)
=> 26320
