Answer:

B: 1 × 10^5

Step-by-step explanation:

B is correct and C is not becasue you have to have the number multiplied by 10 to a power because then you wouldn't know what number to use as the base. I hope this helps. :)

What is the fifth term of the sequence whose first term is 10 and whose common ratio is 1/2?
Cloud [144]

Answer:

D


Step-by-step explanation:

Common ratio of half means that to get each successive terms, you have to multiply the preceding term by half.

Since first term is 10

2nd term is 10*\frac{1}{2}=5

3rd term is 5*\frac{1}{2}=\frac{5}{2}

4th term is \frac{5}{2}*\frac{1}{2}=\frac{5}{4}

5th term is \frac{5}{4}*\frac{1}{2}=\frac{5}{8}


Answer choice D is right.

One circular table has a diameter of 9 ft, and another circular table has a diameter of 20 ft. How much greater is the area of t
morpeh [17]
Smaller circle:
diameter = 9 ft
radius = diameter/2 = (9 ft)/2 = 4.5 ft
A = pi(r^2) = 3.14159 * (4.5 ft)^2 = 63.62 ft^2

Larger circle:
diameter = 20 ft
radius = diameter/2 = (20 ft)/2 = 10 ft
A = pi(r^2) = 3.14159 * (10 ft)^2 = 314.159 ft^2

Difference = larger are - smaller area

Difference = 314.16 ft^2 - 63.62 ft^2 = 250.54 ft^2

Answer: About 251 ft^2

A, B , and C are collinear points: B is between A and C. If AB = 36, BC = 5x - 9 , and AC = 54 , find x
balandron [24]

9514 1404 393

Answer:

  x = 5.4

Step-by-step explanation:

The segment sum theorem tells you ...

  AB +BC = AC

  36 +(5x -9) = 54

  5x = 27 . . . . . . . . . . . subtract 27 from both sides

  x = 5.4 . . . . . . . . . . divide by 5
