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=1/3-1/9
x=3/9-1/9
x=2/9=0.222

Answers

Answer:

No

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.

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.

A local bakery sells 18 bagels for $12.99. How many bagels can be purchased for $20? Round down to the nearest whole bagel.

Answers

You can buy 5 more bagels because if you divide 18 by $12.99 you get 1.385, which would be the price of each bagel. Then you will have about $7.01 left. Now divide $7.01 by 1.385 and it will give you 5.06 bagels. Therefore 18 bagels plus 5 bagels is 23 bagels and so you can buy 23 bagels in total.

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.

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)
