Mathematics
1 answer:
Alchen [17]3 years ago
4 0

Answer:

s = 1

Step-by-step explanation:

Given

s - \frac{1}{2} = \frac{1}{2}

Required

Solve for s

s - \frac{1}{2} = \frac{1}{2}

Add \frac{1}{2} to both sides

s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}

Take LCM

s + \frac{-1+1}{2}  = \frac{1+1}{2}

s + \frac{0}{2}  = \frac{2}{2}

s +0  = 1

s = 1

The cheetah is the fastest land animal, capiable of attaining a speed of 110 km/h. In August 2009 , the world record for the men
lozanna [386]

Answer:

About 3 times faster

Step-by-step explanation:

Cheetah's speed = 110 km / hr

World 100m sprint record :

Speed of sprinter :

Distance / time

100 m / 9.58s

= 10.438413 m/s

Convert Cheetah's speed to m/s

110 km/hr = (110 * 1000)m / (60 * 60 s)

= 110000 m / 3600 s

= 30.55555 m/s

Number of times cheetah is faster than sprinter :

30.55555 m/s ÷ 10.438413 m/s

= 2.927 times

I really need help I’m very confused
Vaselesa [24]

Answer:

10: -11n^5

12: 6k^2 -6k+7

Step-by-step explanation:

Ok so what your gonna do is add or subtract the ones with the same exponent.

so -15+4= -11 since they are both n^5 you can add them so your answer is:

-11n^2

now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)

8k^2-2k^2-5k-k+7

add like exponents

6k^2-6k+7
