Explain how you know that the values of the digit 5 in the numbers 150,000 and 100,500 are not the same.

Answers

Answer:

The place value of both the numbers are different so they are not same.

Step-by-step explanation:

To find : Explain how you know that the values of the digit 5 in the numbers 150,000 and 100,500 are not the same ?

Solution :            

The place value system is

Hundred Th.     Ten Th.     Thousand     Hundred     Tens    Ones

     1                        5                  0                0                0           0

     1                        0                  0                5                0           0

We have seen that,

In the numbers 150,000 the 5 digit is at ten thousand place.

In the numbers 100,500 the 5 digit is at hundred place.

As the place value of both the numbers are different so they are not same.
In the number 150,000 the number is in the ten thousandths place.

In the number 100,500 the number is in the hundredths place.

A total of 60 students in Brooke's school are taking a spanish class this year. This is 25% more than the number of students who take a spanish class last year. Is the answer 45 or 48? Why?

Answers

Number of students taking Spanish class this year in Brooke's school = 60
Percentage increase in the number of students
taking Spanish class from last year = 25%
Then
Number of students that are taking Spanish
class more than last year = 25/100 * 60
                                          = 15
Then
The number of students that took Spanish class last year = 60 - 15
                                                                                             = 45 students
So the number of students that took Spanish class last year was 45. I hope the answer is clear to you and the procedure is also easy for you to understand.

What is the volume of this cylinder? (Use π = 3.14.) A. 703.36 cm3 B. 175.84 cm3 C. 50.24 cm3 D. 354.68 cm3https://static.k12.com/calms_media/media/537000_537500/537008/2/ec4c1bfa8f4ce747e7ec9428bad748c270ad4df6/62178_question.jpg

NEED ANSWER AS SOON AS POSSIBLE

Answers

So, as you should know the volume of a cylinder is  ( pi x r^2 x h ) and since it has a diameter and not the radius you would cut it in half therefore the radius is 4. 8/2=4 4*4= 16 16*14=224 224*3.14= 703.36 So, therefore your answer would be A. Hope this helps!

Please answer 7 and 8 !!!!!!

Answers

Answer:

B and C

Step-by-step explanation:

7 would be B. m = 2

8 would be C m = -1/2

If a line is parallel, then the slop is the same. If it is perpendicular, the it will be the opposite sign and the reciprocal. So parallel would be 2 and perpendicular would be -1/2

Hope this helped! :)

Answer:

7. m= -2

8. m= -1/2

Step-by-step explanation:

picture is taken

Now you can do THIS one, and any OTHER cone
you ever encounter.

What is the answer? 6.3 = 0.7x

Answers

Answer:

x = 9

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 0.7 from both sides:

6.3 = 0.7x

(6.3)/0.7 = (0.7x)/0.7

x = 6.3/0.7

x = 9

x = 9 is your answer.

~

Answer:

9

Step-by-step explanation:

6.3/.7=x

9=x
