9514 1404 393

Answer:

  1. 7.5 m/s
  2. 0.75 m/s
  3. 0.56 m/s
  4. 4 m/s
  5. 1.75 m/s
  6. 1/6 m/s

Step-by-step explanation:

To find the rate, divide the distance by the time.

1. (45 m)/(6 s) = 45/6 m/s = 7.5 m/s

2. (3 m)/(4 s) = 3/4 m/s = 0.75 m/s

3. (2.80 m)/(5 s) = 0.56 m/s

4. (12 m)/(3 s) = 4 m/s

5. (35 m)/(20 s) = 1.75 m/s

6. (10 m)/(60 s) = 1/6 m/s

Which values are solutions to the inequality square root of x is less than 8? A. 55 B. 8 C. -8 D. 4 E. 65 F. -64
Dima020 [189]

9514 1404 393

Answer:

  A.  55

  B. 8

Step-by-step explanation:

We want ...

  √x < 8

  x < 8² . . . . . square both sides

  x < 64

In order for the inequality to make any sense, we must also have ...

  0 ≤ x

So, the solution space is ...

  0 ≤ x < 64

Only answer choices A (55) and B (8) are in that range.

The area of a circle is 28.26 square meters. What is the circle's diameter?
ikadub [295]

Answer: area for circle is  πr² so πr² =28.26 and we can sub 3.14 as pi

3.14*r²=28.26 we can divide by 3.14 to get r² on it's own

r²=28.26/3.14

then we root both sides to get r on it's own

28.26/3.14=9 √9=3

and the diameter is double the radius 3*2=6 so the diameter is 6
