The Pythagorean theorem is a squared plus b squared equals c.
c would equal the hypotenuse.
b is the opposite.
a is the adjacent.
you would do 24 squared plus x squared = 26 squared
after you square 24 and 26
576+x=676
-576. -576
-----------------
x=100
square root it to get
x=10
d is your answer
24²+b²=26²
576+b²=676²
676-576=100
b²=100
Then you square root 100.
b=10
Your answer is 10!
Hope that helps! :D

Experimental vs. Theoretical Probability:
John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even number. He makes a prediction of 20 times. Is it a good prediction? What would your prediction be based on theoretical probability?
Answers
To start the numbers 1 through 6 are on a number cube.
Half of them are even, 2, 4, and 6.
So it makes sense that when you roll the cube 60 times, you should have 30 even numbers. The theoretical probability is 30.
A predication of 20 is 10 less than the expected value of 30.
10 out of 30 is 33%.
The predication is off by 33%, I would argue that it is not a very good prediction.

What is the area of a sector with a central angle of 2pi/9 radians and a diameter of 20.6mm? Use 3.14 for Ali and round your answer to the nearest hundredth.
Answers
A=πr²
A is the area of the circle.
π=3.14
r is the radius of the circle.
- To calculate the area of the sector indicated in the problem, you must apply the following formula:
As=(θ/2π)πr²
As is the area of the sector.
θ is the central angle (θ=2π/9)
π=3.14
r is the radius.
- First, you must find the radius:
r=Diameter/2
r=20.6 mm/2
r=10.3 mm
- Now, you can substitute the values into the formula As=(θ/2π)πr². Then, you have:
As=(θ/2π)πr²
As=(2π/9/2π)(π)(10.3)²
As=(π/9π)(π)(10.3)²
As=(3.14/9x3.14)(3.14)(10.3)²
- Finally, the area of the sector is:
As= 37.01 mm²
The area of the sector rounded to the nearest hundredth is [tex]$37.02 \, \text{mm}^2$[/tex].
To find the area of a sector, we use the formula:
[tex]\[ \text{Area of sector} = \frac{\text{Central angle}}{2\pi} \times \pi r^2 \][/tex]
Given that the central angle is [tex]\( \frac{2\pi}{9} \)[/tex] radians and the diameter (which is twice the radius) is [tex]$20.6 \, \text{mm}$[/tex], the radius is [tex]\( \frac{20.6 \, \text{mm}}{2} = 10.3 \, \text{mm} \)[/tex].
Now, substituting these values into the formula:
[tex]\[ \text{Area of sector} = \frac{\frac{2\pi}{9}}{2\pi} \times \pi (10.3)^2 \][/tex]
[tex]\[ = \frac{1}{9} \times \pi \times 10.3^2 \][/tex]
[tex]\[ = \frac{1}{9} \times 3.14 \times 106.09 \][/tex]
[tex]\[ = \frac{1}{9} \times 333.2086 \][/tex]
[tex]\[ \approx 37.02 \, \text{mm}^2 \][/tex]
Rounded to the nearest hundredth, the area of the sector is approximately [tex]$37.02 \, \text{mm}^2$[/tex].

Subtract 1.05 from a certain number. Multiply the difference by 0.8, add 2.84 to the product then divide the sum by 0.01 and get 700. What is the number?
Answers
The number is 6.25
Explanation:
Assume that the number we are looking for is x
First, we will set up the equations as follows:
1- Subtract 1.05 from the number (assume the result is y):
x - 1.05 = y
2- Multiply the difference by 0.8 (assume the product is z):
0.8(y) = z
3- add 2.84 to the product (assume the result is w):
z + 2.84 = w
4- divide the sum by 0.01, the quotient is 700:
w / 0.01 = 700
Now, we will work backwards as follows:
4) w / 0.01 = 700
w = 0.01 * 700
w = 7
3) z + 2.84 = w
z + 2.84 = 7
z = 7 - 2.84
z = 4.16
2) 0.8y = z
0.8y = 4.16
y = 4.16 / 0.8
y = 5.2
1) x - 1.05 = y
x - 1.05 = 5.2
x = 5.2 + 1.05
x = 6.25
Hope this helps :)
Here's the solution for this,
{(x-1.05).08}+2.84 = 700
.01
0.8x-0.84+2.84 = 700
.01
0.8x + 2 = 700
.01
0.8x + 2 =700 x 0.01
0.8x = 7 - 2
0.8x = 5
0.8 .08
The answer would be 6.25
What is the missing constant term in the perfect square that starts with x²+6x?
Answers
The expression given to us is: x²+6x
Now, we know that the second term is twice the square root of the first and the last terms. Let us call the last term as [tex] y^2 [/tex]. Thus our given expression will become:
[tex] x^2+6x+y^2 [/tex].
Now, since the middle term is 6x and since we know that the second term is twice the square root of the first and the last terms, therefore,
[tex] 6x=2\times \sqrt{x^2} \times \sqrt{y^2} [/tex]
[tex] 6x=2\times x\times y [/tex]
[tex] \therefore y=3 [/tex] (By dividing both sides by 2x)
Therefore, the missing term is 3.

Jake runs either 15 kilometers or 8,500 meters each day.He alternates short and long runs. how many meters farther will he run on his two long run days than on his two short run days?Describe how you found your answer
Answers
1. The answer must be expressed in meters, so, you have to convert 15 kilometers to meters:
1 kilometer------1,000 meters
15 kilometers---x=
x=15x1000/1
x=15,000 meters
2. Then, you have:
On his two long run days=(15,000 meters)(2)=30,000 meters
On his two short run days=(8,500 meters)(2)=17,000 meters
3. Finally, you obtain:
30,000 meters-17,000 meters=13,000 meters
How many meters farther will he run on his two long run days than on his two short run days?
The answer is: 13,000 meters
[tex](15km)( \frac{1000m}{1km} )=15000km[/tex]
We now now that the ditance he covers in his long run days is [tex]15000m[/tex], and in his short run is [tex]8.5km[/tex].
Lets find out the distance he will cover on his two long run days:
[tex]2(15000m)=30000m[/tex]
Likewise, lets find the distance he will cover in his short run days:
[tex]2(8500m)=17000m[/tex]
Now, we just need to find the difference between the tow distances:
[tex]30000m-17000m=13000m[/tex]
We can conclude that we will run 13,000 meters further in his long runs than in his short runs.

A recovering heart attack patient is told to get on a regular walking program. The patient is told to walk a distance of 5 km the first week, 8 km the second week, 11 km the third week and so on for a period of 10 weeks. At that point the patient is to maintain the distance walked during the 10th week. How far will the patient walk during the 10th week? a. Is the sequence arithmetic or geometric? Explain your answer.
Answers
The sequence in this scenario is arithmetic, with the patient increasing their distance walked by 3 km each week. Using the formula for the nth term of an arithmetic sequence, the patient will walk a distance of 32 km during the 10th week.
Explanation:The sequence in this case is arithmetic. This can be determined by observing that the difference between the distances walked each week is consistent. In this case, the difference is 3 km, as the patient increases their distance by 3 km each week.
To find out how far the patient will walk during the 10th week, we can use the formula for the nth term of an arithmetic sequence:
an = a1 + (n-1)d
Where an is the nth term, a1 is the first term, n is the number of terms, and d is the common difference.
Given that the first term is 5 km, the common difference is 3 km, and we want to find the 10th term, we can substitute the values into the formula:
a10 = 5 + (10-1)3
a10 = 5 + 9 * 3
a10 = 5 + 27
a10 = 32
Therefore, the patient will walk a distance of 32 km during the 10th week.

Answers
(90km/hr)/50km=1.8

Answer:
He will reach 0.02 hours before me.
Step-by-step explanation:
A we know that,
Speed = Distance ÷ Time
Here we have given that Distance = 50 km
My Speed is 90 km/h
So time taken to complete my trip = Distance ÷ Speed
⇒ My Time = 50 ÷ 90 = 0.55 hours
Also, Speed of my friend is 95 km/h
So time taken to him to complete his trip = Distance ÷ Speed
His Time = 50 ÷ 95 = 0.53 hours
Thus he will reached before me as his speed is fast
He will reach 0.55 - 0.53 = 0.02 hours before me.

To prove tan(π/2 - x) = cot x, we use the co-function identity for tangent and cotangent, showing the relation of these functions in complementary angles. This identity confirms that tan(π/2 - x) equals cot x.
To prove the identity tan (π/2 - x) = cot x, we can use a fundamental trigonometric identity. Here's how:
Recall the co-function identity: tan (π/2 - x) = cot x. This identity is derived from the relationship between tangent and cotangent in complementary angles.
Using the identity tan (π/2 - x) = cot x, we know that the tangent of an angle's complement is equal to the cotangent of the angle.
By definition, tan θ (tangent) is the ratio of the opposite side to the adjacent side in a right triangle. For the complementary angle, the roles of the opposite and adjacent sides switch, which aligns with the definition of cot x (cotangent), i.e., the adjacent side over the opposite side.
This proves that tan (π/2 - x) = cot x.
