A sprinter travels a distance of 100 m in a time of 8.96 seconds.
What is the sprinter's average speed rounded to 4 sf

Answers

Answer 1

The average speed is 40.176 Km/h.

What is Average speed?

The average speed is the total distance traveled by the object in a particular time interval.

Given:

distance = 100m

time= 8.96 seconds

So,

average speed = distance/time taken

= 100/8.96

= 11.16 m/s

and in Km/h

= 11.16* 18/5

= 40.176 Km/h

Hence, the average speed is 40.176 Km/h.

how would you prefer to see your quiz score,as a fraction or as a percent? Explain. (what would you choose and why?)​

Answers

For me, a percent is easier to think about.  Knowing I scored 80% make sense.  80%, like 80¢ out of a dollar, makes sense and I can relate to it.

If you tell me I scored 52/65, I can't relate to that as easily, even though that's still 80%.

Becky has 30 T-shirts in a drawer: 12 concert shirts, 8 team shirts, and 10 plain shirts. Of
the 10 shirts she randomly selects to give to charity, 3 are concert shirts. How does this
frequency compare to the expected frequency based on the probability of randomly
selecting a concert T-shirt?

Answers

Answer:

The chance of her selecting a Cocert shirt are 12/30 which means therw is more probability she would choose at least one and the least probability to choose a Team sirt since the odds are 8/30 so it is expected she would select 4 concert shirts not 3, at lest for me.

Three times a number increased by 44 is the same as the opposite of the number. Find the number

Answers

Answer:

- 11

Step-by-step explanation:

let the number be n then 3 times the number is 3n and the opposite is - n

3n + 44 = - n ( add n to both sides )

4n + 44 = 0 ( subtract 44 from both sides )

4n = - 44 ( divide both sides by 4 )

n = - 11

The required number is - 11

Answer:

the remainder: 5

Answer:   6x + 4 + (⁵/ₓ ₊ ₅)

Step-by-step explanation:

I like to use long division to work these problems:

                        6x   +  4          

        (x+5)  ║ (6x² + 34x + 25)

                    - (6x  + 30x)   ↓

                                   4x + 25

                               - (4 x + 20)  

                                             5

                     (6x^2 + 34x + 25)/(x+5)  = 6x + 4 with a remainder of 5

  ⇒ (6x² + 34x + 25)/(x+5)  =  6x + 4 + (⁵/ₓ ₊ ₅)

The value of x is ___°, and the value of y is ___°.

Answers

Answer:

The value of x is 60°, and the value of y is 50°.

Step-by-step explanation:

50°+70°+x°=180°

x=180°-120°

x=60°

similarly the angle on the left side of x will be

70°

All these angles form 180°(linear pair)

hence, 70°+60°+y°=180°

130°+y°=180°

y°=180° - 130°

y°=50°

Answers

Answer:

75 m

Step-by-step explanation:

Let s- shorter walkway, l- longer walkway.

Given:

s/l = 3/5s = 45 m

Find the length of l:

45/l = 3/5l = 45*5/3l = 75 m

Answer:

[tex]\sf\longmapsto \: length = 75 \: metres[/tex]

Step-by-step explanation:

Now let's find out what's the length of the long walkway–

[tex]\sf\longmapsto \: \frac{3}{5} = \frac{45}{\: length\: of \:longer\: walkway} [/tex]

[tex]\sf\longmapsto \: \: length\: of \:longer\: walkway= \frac{45 \times \: 5 }{3} [/tex]

Sam is paid $50 per room that he paints and he can paint a room in exactly 2 hours. On sunday, sam hopes to make atleast $150 painting rooms and can work for exactly 10 hours. Which of the following sets represents the range of money (m) that sam can make without violating either his monetary or time restriction?
A. m= {150,250}
B. m={0,150}
C. m={0,250}
D. m={100,250}

Answers

Answer: A, {150,250}

Step-by-step explanation:

In 10 hours he can do 5x2 hours work.  or 5x$50 = $250 for 5 rooms

$150 is 3x $50 or 3x2 hours work.

He can work 6 hours and make $150

or he can work 10 hours and make $250

the range he can earn so that he makes at least $150 and no more than 10 hours is$150 to $250

($150,$250) in interval notation for working 6 to 10 hours (6,10)
