Anna runs at a rate of 12\frac{miles}{hr} to reach her goal.

<u>Step-by-step explanation:</u>

Here we have , Anna wants to run 10-mile race in under 50 minutes. We need to find What rate, miles per hour, must she maintain to reach her goal. Let's find out:

Anna wants to run 10-mile race in under 50 minutes , i.e. she runs at a rate of:

⇒ \frac{Distance}{Time}

⇒ \frac{10miles}{50min}

⇒ 10miles(\frac{1}{50min})    

⇒ 10miles(\frac{1}{50\frac{1}{60}hr})              {  1 min = \frac{1}{60}hr }

⇒ 10miles(\frac{60}{50hr})

⇒ 10(1.2)\frac{miles}{hr}

⇒ 12\frac{miles}{hr}

Therefore , Anna runs at a rate of 12\frac{miles}{hr} to reach her goal.

Determine if the sequence is geometric. If it is, find the common ratio.
Akimi4 [234]

Answer:

  1. -1/3
  2. not geometric
  3. -5
  4. 4

Step-by-step explanation:

You find the ratio of terms by dividing the second by the first. If the ratio is the same for all adjacent pairs of terms, it is a "common" ratio.

1) (2/3)/-2 = -1/3

  (-2/9)/(2/3) = -1/3

  (2/27)/(-2/9) = -1/3 . . . . . the common ratio is -1/3

___

2) 2/0 = undefined . . . . not a geometric sequence

___

3) -10/2 = -5

  50/-10 = -5

  -250/50 = -5 . . . . . the common ratio is -5

___

4) 4/1 = 4

  16/4 = 4

  64/16 = 4 . . . . . the common ratio is 4

If the side that is 6 units long is the base of this parallelogram, what is its corresponding height.
zmey [24]

Answer:

4 units.

Step-by-step explanation:

No matter which side is chosen as the base, the area of the parallelogram is the product of that base and its corresponding height. With this we are trying to get 24 as area. So, since 6 units x 4 units = 24 units.

Thus, We can say the base is 6 units and height is 4 units.
