Answer:

Step-by-step explanation:

hello :

if : r the radius ( r ≠0)

the circumference is : 2πr

the area is : πr²

so : πr² = 2πr

simplify by : r π you have : r=2

59 is D
because with the point (-3,7) you substitute it into the equation, making it: 7=4x+b. solve for b. then you have y=4x+19. work out the algebra in the possible choices and whatever equals y=4x+19 will be the answer. in this case, its D.

60 is C
same as above, you do the algebra of the equation. bring the one over after doing distribution with the 4 and voila!

61 is A
a relatively easy one, all you do is the the slope -4 where m goes, and 3 where b goes. y= -4x+3

62 is C.
this one requires more work.
chose one of the points, in this case (2,7) and put them into the equation.
but wait, you need a slope!
you get that use the formula (y2-y1)/(x2-x1) which will be
(7-5)/(2-3) which will be
-2.
now you have y-7= -2(x-2)
voila!

63 is C. y= 1/2x+3

64 is B. (3, -5)

66 is B. negative. the line goes \ ( not / which is positive)

67 would be A. because it is positive and the I and the E are in the right places.

70 is C. 2/3. as before, remember we can but the points into this equation and have (6-4)/(3-0) which = 2/3

71 is D. y= 3x+10

72 is C. a third degree monomial

Explain how your knowledge of place value helps you divide a number in the thousands by whole numbers to 10 give an example to s

lapo4ka [179]

Answer with Step-by-step explanation:

The value of a digit due to its position in a number is called as place value.

For example, there's a number

23450

2 is in ten thousands place and it has a place value of 20,000

3 is in thousands place and it has a place value of 3000

4 is in hundreds place and it has a place value of 400

5 is in tens place and has a place value of 50

0 is in unit or ones place and has a value of 0

When we divide the number by 10, we move every digit from its current place value to the right.

23450 divided by 10 = 2345

Now,

2 is in thousands place and it has a place value of 2,000

3 is in hundreds place and it has a place value of 300

4 is in tens place and it has a place value of 40

5 is in unit or ones place and has a place value of 5
