Acheetah runs 900 meters in 30 seconds. how fast is it going? a. 3 meters/second b. 30 meters/second c. 0.03 meters/second d. not enough information

B. 30 meters/second

Step-by-step explanation:

Given : A cheetah runs 900 meters in 30 seconds.

To Calculate : Speed of Cheetah

Solution :

We know that cheetah runs 900 meters in 30 seconds

Distance traveled by cheetah = 900 meters

Time taken by cheetah to cover distance of 900 meters = 30 seconds

Now to calculate speed we will use formula :

⇒

⇒

Thus , The speed of cheetah is 30 meters/second

Hence OPTION B is correct

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
