Find a radical expressions for the perimeter of the shaded triangle Simplify the expression.​

Answer:

50

Step-by-step explanation:

15/x=30/100

30x=1500

x=50

there are 50 apples in the box.

part/whole = percent/100

15/x = 30/100

30x = 1500

x = 50

Answer: B

Step-by-step explanation:

Answer:

B. 5 11/12

Step-by-step explanation:

Simplify the following:

1 + 7/12 + 4 + 1/3

Put 1 + 7/12 + 4 + 1/3 over the common denominator 12. 1 + 7/12 + 4 + 1/3 = 12/12 + 7/12 + (12×4)/12 + 4/12:

12/12 + 7/12 + (12×4)/12 + 4/12

12×4 = 48:

12/12 + 7/12 + 48/12 + 4/12

12/12 + 7/12 + 48/12 + 4/12 = (12 + 7 + 48 + 4)/12:

(12 + 7 + 48 + 4)/12

Answer: 71/12 = Convert to a mixed number:

71/12

Divide 71 by 12:

1 | 2 | 7 | 1

12 goes into 71 at most 5 times:

| | | 5

1 | 2 | 7 | 1

| - | 6 | 0

| | 1 | 1

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:

| | | 5 | (quotient)

1 | 2 | 7 | 1 |  

| - | 6 | 0 |  

| | 1 | 1 | (remainder)

The quotient of 71/12 is 5 with remainder 11, so:

Answer: 5 11/12

Answer:

7/2

Step-by-step explanation:

Answer:

3 1/2 or 7/2

Step-by-step explanation:

To divide fractions, you keep change flip, so you would get to 7/9*9/2 or 63/18. You can divide both of these numbers by 3 to get 21/6, which you can divide by 3 again to get 7/2

Answer: He is incorrect.

Step-by-step explanation:

The question says:

"tea drinkers in Canada is 4:1"

We only have that, so i guess that this means:

"The ratio of nonregular tea drinkers to regular tea drinkers in Canada is 4:1"

The ratio 4:1 means that for each 4 non-regular tea drinkers, there is one regular tea drinker.

Now let's multiply both by 100.

For each 400 nonregular tea drinker, there are 100 regular tea drinkers, if we add them we have a total of 500

Then the statement would be if 500 people were surveyed, 100 of the would most likely be regular tea drinkers.

Answer:

  B.  13 units

Step-by-step explanation:

The distance formula can be useful.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((11-(-1))² +(-8-(-3))²) = √(12² +(-5)²) = √(144 +25) = √169

  d = 13

The length of AB is 13 units.

_____

If you're familiar with a few of the small Pythagorean triples, you would know that for integer coordinates, an integer answer is most likely to be 13. The x- and y-differences in coordinates being 12 and 5 confirm that the (5, 12, 13) triple is being used here.

There are no Pythagorean triples with hypotenuse values of 11, 12, or 14. (3, 4, 5) can be doubled to give (6, 8, 10), but 10 is not a choice.

Answer:

B. Reflected over the y-axis and rotated 180°

Step-by-step explanation:

A(-4, 2) Reflected over the y-axis (x, y) → (-x, y) → A'(4, 2)

A'(4, 2) → rotated 180° (x, y) → (-x, -y) → A"(-4, -2)

The set of transformations that can be applied to ABCD, to create A″B″C″D″ is a reflection over the y-axis, followed by a rotation of 180°

"It is the production of the image of a figure through two or more transformation."

"It is a geometric transformation where all the points of an object are reflected on the line of reflection."

"It is a transformation in which the object is rotated about a fixed point."

For given question,

The rectangle ABCD is formed by ordered pairs A at (-4, 2) , B at (-4, 1), C at (-1, 1), D at (-1, 2)

The rectangle A″B″C″D″ is formed by ordered pairs A" at (-4, -2), B" at   (-4, -1), C" at (-1, -1) , D" at (-1, -2)

We can observe that the coordinates of ABCD are of the form (-x, y)  where x, and y, are positive numbers

The form of the ordered pair of the vertices of the A″B″C″D″ is (-x, -y)

The coordinates of the point (-x, y) after reflection over y-axis would be of the form (x, y)

And after rotation of 180° the coordinates would be (-x -y)

Therefore, the set of transformations that can be applied to ABCD, to create A″B″C″D″ is a reflection over the y-axis, followed by a rotation of 180°

Answer:

6.48074069 …

Step-by-step explanation:

if you are asked to simplify the radical, then it is already in its simplest form and cannot be simplified further.

If you are asked to solve for the answer, then a simple calculator entry will give us √42 = 6.481 (nearest thousandths)

Answer: 300 x 500=150,000

Step-by-step explanation: Here, they're asking you to create a ballpark estimate by rounding. Since most people can't multiply 325 by 454 in their heads, it's more ideal to simply round to get an estimate first. Here, the numbers are rounded to the nearest hundred for a more friendly equation. The ≈ sign means approximately equals, or about, which indicates that your answer is close but not exact.

Hope this helps,

Answer:

The number of license plates that can be made is 1,757,600

Step-by-step explanation:

Here, we want to calculate the number of possible license plates

We do not have any restrictions here.

the number of digits is 0-9 making 10

Alphabets A-Z making 26

For two letters, one digit , one letter , one digit

1st letter

Number of choices is 26

second letter 26 too

1st digit 10 choices

third letter = 26 choices

last digit = 10 choices

Total number of choices will be;

26 * 26 * 10 * 26 * 10 = 1,757,600

Answer:

The value is    [tex]k = 50\%[/tex]

Step-by-step explanation:

Generally quartiles divide observation into four parts  

   The first quartile takes up 25% of the observation

    The second quartile takes up 50% of the observation

    The third quartile takes up  75% of the observation

      The fourth quartile  takes up 100% of the observation

Generally the percentage of the observation that lies between the first and the third quartile is mathematically represented as\

         [tex]k = 75\% - 25\%[/tex]

=>       [tex]k = 50\%[/tex]  

Using the concepts of quartiles and percentiles, it is found that 50% of the observations in a distribution lie between the first quartile and the third quartile.

To find the percentage between, we subtract the percentiles, hence:

75 - 25 = 50

50% of the observations in a distribution lie between the first quartile and the third quartile.

A similar problem, which involves percentiles, is given at https://brainly.com/question/24495213

Answer:

All explained below.

Step-by-step explanation:

The sources of errors are;

1) Instrumental Errors: This could be as a result of wrong calibration of equipment.

2) Observational Systematic errors: An example of this is parallax error while taking a reading.

3) Environmental random errors: In this type of error, a slight change in the temperature of humidity in the lot could possibly affect the accuracy of the measurement.

4) Observational random errors: This refers to errors gotten when the values are incorrectly read or incorrectly interpolated.

5) Environmental systematic errors: An example of this is that the current supplied to the instrument taking the reading may be low. Thus, this may affect effective reading.

6) Theoretical systematic errors: This could arise from over simplification of the experimental model. An example of this is that the experiment might require a totally frictionless surface which may not be achievable. And this will lead to wrong measurement.

Minimizing the errors:

1) Instrumental Errors can be minimized by ensuring proper calibration of equipment before use.

2)Observational Systematic errors can be minimized by ensuring readings are not taken at an angle.

3)Environmental random errors could be minimized by carrying out the experiment in a relatively good laboratory under fair weather conditions.

4)Observational random errors can be minimized by ensuring that the results from the readings are properly collated and the rightly interpolated as the case may be.

5)Environmental systematic errors can be minimized by ensuring stable power source to the instrument being used for the reading.

6)Theoretical systematic errors could be minimized by taking an average of at least 3 tests result to get a fair representation of the final result.

Answer:

1700π in³/s

Step-by-step explanation:

Volume of a cone is expressed as

V = 1/3πr²h

Given

dr/dt = 5in/s

dh/dt = 3in/s

radius r = 50in

h = 20in

Required

dV/dt = ?

dV/dt = dV/dr * dr/dt + dV/dh*dh/dt

dV/dr = 1/3πh (5) + 1/3πr²(2)

dV/dt = 1/3π(20)(5)+1/3 π(50)²(2)

dV/dt =  100π/3 + 5000π/3

dV/dt = 5100π/3

dV/dt = 1700π in³/s
