Answers

Answer 1

Answer:

16/3 or 5.33333

Step-by-step explanation:

You will do [tex]\frac{y-y}{x-x}[/tex] make sure it is y2 - y1 and x2 - x1.  So lets plug in your numbers. 31 + 1/ 4 +2 = 32/6 = 16/3 simplified. I turned it to + because two - - equals a +.

Answers

Answer:

We are given a diagram with different rays and lines.

Note: A line can be extend more and more upto infinitely length from both of the ends but a ray can be extend from end only.

We need to find the rays for the line BE.

We can see BE line has a point A in between line.

So, we can name the rays formed with end point A as AB and AE.

Therefore,  AB and AE rays are part of line BE.

So, the correct option is 2nd option :

AB and AE.

what is equivalent to (10+7r-r^2)+(-6r^2-18+5r)

Answers

Answer:

- 7r² + 12r - 8

Step-by-step explanation:

Given

(10 + 7r - r² ) + (- 6r² - 18 + 5r) ← remove parenthesis

= 10 + 7r - r² - 6r² - 18 + 5r ← collect like terms

= - 7r² + 12r - 8

The expression (10 + 7r - r² ) + (- 6r² - 18 + 5r) is equivalent to - 7r² + 12r - 8 after applying the property.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The expression is:

(10 + 7r - r² ) + (- 6r² - 18 + 5r)

Using distribution property:

After applying the above property the expression can be written as:

10 + 7r - r² - 6r² - 18 + 5r

Adding like terms:

- 7r² + 12r - 8

Thus, the expression (10 + 7r - r² ) + (- 6r² - 18 + 5r) is equivalent to - 7r² + 12r - 8 after applying the property.

how can you tell whether a square root of a whole number is rational or irrational

Answers

Answer:

Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period. The director randomly selects 64 different 24-hour periods and determines the number of admissions for each. For this sample, X = 396 and S = 100. Using the sample standard deviation as an estimate for the population standard deviation, what size sample should the director choose if she wishes to estimate the mean number of admissions per 24-hour period to within 1 admission with 99% reliability, what size sample should she choose?

Answer:

Sample size n = 16

Step-by-step explanation:

We use the formula for Margin of Error for the question

Margin of Error = z × Standard deviation/√n

Margin of Error = 1

z score for 99% confidence interval = 2.576

Standard deviation = 100

1 = 2.576 × 100/√n

1 × √n = 257.6

√n = 257.6/1

n = √257.6

n = 16.049922118

Approximately = 16

Therefore, the sample size = 16

A garbage company recycles ½ tons of plastic every 3 minutes. At this rate, approximately how many tons of plastic does the company recycle in two days?

Answers

Answer:

Total number of minutes in 2 days = 2880

Total time used for recycling garbage in 2 days = 2880/3 = 960

If 3 minutes = 1/2 tons

Then 960 minutes = 960*1/2 = 960/2 = 480

Therefore 480 tons of garbage where recycled in 2 days

The exponents and variables determine what comes first.  In [ 11x³ - 6x² + 5x ], we can see that the exponents are going from greatest to least and the last number doesn't have an exponent so it goes last. Essentially we can think of this as sorting each part from greatest to least using exponents -> variables -> number to determine that.

9n - 6 = 5n + 18
Solve

Answers

Answer:

n = 6

Step-by-step explanation:

9n - 6 = 5n + 18

Subtract 5n from each side

9n-5n - 6 = 5n-5n + 18

4n -6 = 18

Add 6 to each side

4n -6+6 = 18+6

4n = 24

Divide each side by 4

4n/4 = 24/4

n = 6

9n - 6 = 5n + 18
- 5n on both sides
4n - 6 = 18
Subtract 6 on both sides
4n = 12
Divide both sides by 4
n = 3

the volume of the truck is 162 yards. To find how many cubes will fit in each dimension, divide that length by the side of the cube

Answers

Answer:

180 cubes would be fit inside the truck

Step-by-step explanation:

well we know 1 cube is 1/10 of a yard

so let’s make it a easier number and say 10 cubes is 1 yard (you multiply 10 on each side, as long as you multiply the same number, which can be any number but I use 10 since it’s easier, on both sides, it’ll be the same thing.

so 162/10=16

So 16, 10 cubes si we multiply those two and you’ll get 160.

But there’s 2 yards not filled yet, we know that 1 yard is 10 cubes, so 2 yards would be 20 cubes.

so 160+20=180

Help!! 50 Points!!!Remember how to calculate currency conversions:To determine the currency conversion, multiply the amount of U.S. dollars by the currency exchange rate. For example, since the currency exchange rate for U.S. dollars to Nearlandian dollars is 1 USD = 5 NRD, then 20 U.S. dollars is equivalent to 100 Nearlandian dollars, because 20 x 5 = 100. If you have 50 Nearlandian dollars to convert back to U.S. dollars, you would divide by the exchange rate. Thus, 50 Nearlandian dollars is equivalent to 10 U.S. dollars, because 50 / 5 = 10. 1.
