Identify the numeric order of these fractions and mixed numbers from largest to smallest in the final form with common denominators 1 1/2, 1/4, 1 3/4, 5/6.

Answers

Answer:

1 3/4, 1 1/2, 5/6, 1/4

with a common denominator, it looks like this

21/12 = 1 3/4, 18/12 = 1 1/2 10/12 = 5/6 3/12 = 1/4

The order of the fraction from largest number to smallest number is 1 3/4, 1 1/2, 5/6, and 1/4.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data given in the question,

1 1/2 = 3/2 = 1.5

1/4 = 0.25

1 3/4 = 7/4 = 1.75

5/6 = 0.83

So, the order from largest to smallest number is:

1 3/4, 1 1/2, 5/6, and 1/4.

Now, with a common denominator it will be:

21/12 = 1 3/4, 18/12 = 1 1/2 10/12 = 5/6 3/12 = 1/4

The frequency of people compared to the number of monthly text messages sent and received by a class are shown in the histogram.

A histogram titled Daily Text Messages. The x-axis is labeled Number of Sent Texts and has intervals of 1 to 15, 16 to 30, 31 to 45, 46 to 60, 61 to 75, 76 to 90, and 91 to 105. The y-axis is labeled Frequency and starts at 0, with tick marks every 2 units up to 12. There is a shaded bar for 1 to 15 that stops at 1, for 31 to 45 that stops at 3, for 46 to 60 that stops at 4, for 61 to 75 that stops at 4, for 76 to 90 that stops at 5, and for 91 to 105 that stops at 8. There is no shaded bar for the 16 to 30 interval.

Which of the following best describes the shape of the data, and why?

The data is symmetric because the majority of students sent fewer than 45 text messages.
The data is symmetric because some students have phones and some do not.
The data is skewed because most text messages are replied to and cause the number to be at least twice what it was originally.
The data is bimodal because the popular number of text messages to send is between 91 and 105.

Answers

Answer:

Step-by-step explanation:

Based on the given information, the histogram shows the frequency of people compared to the number of monthly text messages sent and received by a class. The shaded bars on the histogram show the number of students that fall within each range of text messages.

Since the bars are mostly concentrated towards the right side of the histogram, and there are a few students who send a much larger number of text messages than the rest, we can say that the data is skewed to the right. This means that the majority of students send a small number of text messages, while a few students send a much larger number of text messages.

Therefore, the best description of the shape of the data is: The data is skewed because most text messages are replied to and cause the number to be at least twice what it was originally.

Answer with a proper explanation

Answers

Answer:

15 sides

Step-by-step explanation:

As we know the full angles of a polygon is 360°

And

Each side has angle 24°

So,

n = 360/24

n = 15 sides

I hope my answer helps you.

Answer:
The polygon has 5 sides.

Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.

=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

25c + 48a when c = 12 and a = 4.
( I think the answer is 492 but I'm not sure. Please correct me if I'm wrong. )

Answers

Answer:

492

Step-by-step explanation:

You want the value of (25c+48a) when c=12 and a=4.

Evaluation

Put the numbers in place of the corresponding variable and do the arithmetic. A calculator can help you out, if needed.

25c +48a = 25·12 +48·4 = 300 +192 = 492

Additional comment

There are some mental math tricks that can help you do this in your head:

25 = 100/4, so 25·12 = (100/4)·12 = 100·(12/4) = 100·3 = 300

4 = 2·2, so 48·4 = (48·2)·2 = 96·2 = 192

Doubling or halving a number is generally pretty easy, so multiplication or division by 2, 4, or 8 can be accomplished by repeatedly multiplying or dividing by 2.

25c + 48a when c = 12 and a = 4. ( I think the answer is 492 but I'm not sure. Please correct me if I'm

Your answer is 492
48 x 4 =192
Multiply 25 x 12
And add you get 492

The time needed for the rocket to be 30 feet of the ground is given as follows:

t = 9.6 seconds.

How to obtain the time needed?

The quadratic function giving the rocket's height after t seconds is given as follows:

h(t) = -16t² + 150t + 70.

The rocket will be 30 feet of the ground when:

h(t) = 30.

Hence:

-16t² + 150t + 70 = 30

16t² - 150t - 40 = 0.

The coefficients of the quadratic function are given as follows:

a = 16, b = -150, c = -40.

Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

t = 9.6 seconds.

Solve the equation for x
25-3x=40

Answers

x=-5

explanation:
you have to do inverse operation, so subtract 25 and -25 and then on the other side you do 40-25, which equals 15. After that you get -3x=15 and divide -3 on both sides.

The answer will be -5
What ever you do to one side you do to the other

First subtract 25 from itself and do the same to the total
25-3x=40 -3x=15

Next divide -3 from itself and the total ( keep in mind that when you multiply or divide a negative by a positive the answer will be a negative)
-3x=15 X=-5
