Step-by-step explanation:
sum of three no =94
first no =X
second no x-8
third no =4(x-8)
X+(x-8)+4x-32=94
6x-40=94
6x=94-40
6x=54
X=54/6
X=9
Answer: The first number is 9, the second number is 17, and the third number is 68.
Step-by-step explanation:
Using the given information we will represent the first number by f , the second number by s, and the third number by t.
The first number is 8 less than the second and we will represent that by the equation, f= s-8
The third number is 4 times the second and it will be represented by the expression, t= 4s
We know the sum of the numbers has to equal 94 so we will add them.
The first number is s-8, the second is s, and the third is 4s.
(s - 8) + (s) + 4(s) = 94 Solve for s to find the second number.
6s - 8 = 94
+8 +8
6s = 102
s = 17
The second number is 17 and we will input 17 in for s to solve for the first and third numbers.
f= 17 - 8
f= 9
The first number is 11.
t= 4(17)
t = 68
The third number is 68.
Check: Now add them to see if they equal to 94.
9+ 17 + 68 = 94
94 = 94

At a Halloween fair, you see a huge Ferris wheel. There are ten seats on the wheel, with two people placed on each seat. Every minute, a seat passes by the exit platform. The Ferris wheel opened for 30 minutes at 11 a.m. and doubled its speed after fifteen minutes. How many people rode the wheel during this time?
Answers
Answer:
i believe 90 would be your answer.
Step-by-step explanation:
There are 10 seats and 2 people on each
2 times 10 = 20
the wheel was open for a total of 45 min
since every minute people are being switched out you have to do 2 times 10 4 times witch gives you 80 and the last 5 min you count 2 for each min and then your final answer will be 90.

The sides of the triangle do not satisfy the Pythagorean Theorem.
Step-by-step explanation:
If we are given the three sides to a triangle, and we are asked to find out if it is a right triangle, we will have to see if the sides of the triangle satisfies the Pythagorean Theorem. The Pythagorean Theorem is:
a² + b² = c²
where c is the hypotenuse and a and b are the other two sides.
So we can see from the image that 28 would be the length of the "hypotenuse" and 19 and 20 would be the lengths of the other two sides. Lets see if these values satisfy the Pythagorean Theorem:
19² + 20² = 28²
361 + 400 = 784
761 ≠ 784
So no, the triangle is not a right triangle because the sides does not satisfy the Pythagorean Theorem.
I hope you find my answer and explanation to be helpful. Happy studying.

Step-by-step explanation:
Answer:

Step-by-step explanation:
This happens because the inside angles of a triangle always add up to 180º no matter what type of triangle it is. So if two triangles have two equal measurements then the third will also be equal. This is according to the Triangle Sum Theorem.

What is the value of X+1/9=1/3
Answers
Answer:
x = 2/9
Step-by-step explanation:
x + 1/9 = 1/3
Subtract 1/9 from each side
x + 1/9 -1/9 = 1/3 - 1/9
Get a common denominator
x = 1/3 *3/3 - 1/9
x = 3/9 -1/9
x = 2/9
x=3/9-1/9
x=2/9=0.222
The authors of a certain paper describe a study to evaluate the effect of mobile phone use by taxi drivers in Greece. Fifty taxi drivers drove in a driving simulator where they were following a lead car. The drivers were asked to carry on a conversation on a mobile phone while driving, and the following distance (the distance between the taxi and the lead car) was recorded. The sample mean following distance was 3.80 meters and the sample standard deviation was 1.19 meters.
Construct a 95% confidence interval (in meters) for μ, the population mean following distance while talking on a mobile phone for the population of taxi drivers. (Round your answers to three decimal places.)
Answers
Answer:
CI = (3.462, 4.138)
Step-by-step explanation:
We are given;
Sample mean; x¯ = 3.8
Sample standard deviation; s = 1.19
Sample size; n = 50
DF = n - 1 = 50 - 1 = 49
Confidence level; CL = 95%
Significance level = (1 - 0.95)/2 = 0.025
Now,from the table attached using DF = 49, significance level = 0.025, one tail and by interpolation, we have; t = 2.01
Now, formula for confidence interval is;
CI = x¯ ± t(s/√n)
CI = 3.8 ± 2.01(1.19/√50)
CI = 3.8 ± 0.338
CI = (3.8 - 0.338, 3.8 + 0.338)
CI = (3.462, 4.138)

devisibility rules for 3, 6, and 9
Answers
Answer:
★ Divisibility rule for 3 -
If the sum of all the digits divisible by 3 then the number is divisible by 3.
Here, we take an example for better understanding -
Example 1 - 3525
Add up the digits - 3 + 5 + 2 + 5
→ 15
As, 15 is divisible by 3. So, 3525 is a factor of 3.
★ Divisibility rule for 6 -
A number is to be divisible by 6 , if the number is also divisible by 2 and 3.
Example 2 - 132
Add up the digits = 1 + 3 + 2 = 6
As, 6 is divisible by 2 and it's also divisible by 3. Then, 132 is a factor of 6.
★ Divisibility rule for 9 -
If the sum of all the digits is divisible by 9 then the number is divisible by 9. Just like we'd in 3.
Example 3 - 1052
Add up the digits - 10 + 5 + 2 = 17
As, 17 is not divisible by 9. So, 1052 is also not divisible by 9.
