Usain Bolt ran the 2012 Olympic 100-meter race in 9.63 seconds. If he runs at this rate on a road with a speed limit of 25 miles

per hour, how will his speed compare to the speed limit? Justify your answer. (25 mi/hr = 40,234 meters/hr)

Answer:

3874.5342

Step-by-step explanation:

9.63 divide by 100 = 0.0963

0.0963x40 234= 3874.5342

Answer:

Step-by-step explanation:

The speed limit is about 11.2 meters per second. Usain is running 10.38 meters per second. So he is running slower than the speed limit.

100 m / 9.63 s = 10.38 m/s

He ran at about 10.38 m/s.

10.38 m/s = 37,368 m/hr

(40,234 m/hr) / (3600 s/hr) = 11.2 m/s

The speed limit is about 11.2 m/s.

His speed will be less than the speed limit.

If M is the set of all square of integers that are less than 100 and N is the set of all positive odd numbers that are under 15,
ollegr [7]

A set is simply the group of numbers.

  • <em>The set of M and N are: </em>M = \{1,4,9,16,25,36,49,64,81\}<em>  and </em>N= \{1,3,5,7,9,11,13\}<em>.</em>
  • <em>The set of M n N is: </em>M\ n\ N = \{1,9\}<em>.</em>
  • <em>The set of  M u N is: </em>M\ u\ N = \{1,3,4,5,7,9,11,13,16,25,36,49,64,81\}<em />

<u>(a) The set of M and N</u>

Given that:

M = squares of integers less than 100

N = Positive odd numbers less than 15

So, we have:

M = \{1,4,9,16,25,36,49,64,81\}

N= \{1,3,5,7,9,11,13\}

<u>(b) M n N and M u N</u>

M n N is the set of common elements between sets M and N.

So, we have:

M\ n\ N = \{1,9\}

M u N is the set of all elements in sets M and N.

So, we have:

M\ u\ N = \{1,3,4,5,7,9,11,13,16,25,36,49,64,81\}

Which are sums of perfect cubes? Check all that apply.
vichka [17]
I think these are the sums of perfect cubes. 

A = (2x²)³ + (3)³
B = (x³)³ + (1)³
D = (x²)³ + (x)³
E = (3x³)³ + (x^4)³

What is the value of x? <br><br> A. 68° <br> B. 62° <br> C. 112° <br> D. 124
bearhunter [10]
The triangle drawn in the question shows a small single line drawn across two sides of the triangle.

This means that those two sides are equal in length.

Hence, the triangle is an isosceles triangle.

In isosceles triangles, the angles opposite to the equal sides are also equal.

Hence, we know that the two angles other than x is 56°.

The sum of the interior angles of a triangle is 180°

x + 56 + 56 = 180

x = 180 - 56 - 56

x = 180 - 112

x = 68°

Hence, the answer is A.
