4 0

Answer:

The number has 1 significant digit.

Step-by-step explanation:

Consider the provided number.

The numbers that contribute to the significance of the total number value are significant figures. All the numbers are significant digit except all leading 0.

Rules:

  • Non-zero digits are significant.
  • If the zeros is in between non-zero digits then it will be significant.
  • If the zeros are leading then they are not significant.
  • if the zeros are at the right of the last non zero digit then they are significant (Trailing Zero).

Now consider the number .00000004

Since all the zeros are leading that means they are not significant.

The number 4 is a significant digit as it is a non zero number.

Hence, the number has 1 significant digit.

Izumi is running on a quarter-mile oval track. After running 110 yards, his coach records his time as 16 seconds.
pickupchik [31]

Answer:

14.04 miles per hour

Step-by-step explanation:

The problem is asking for Izumi's speed. The formula of speed is:

  • s = \frac{d}{t} , where "s" means speed, "d" means distance and "t" means time.

The problem is also asking for the unit<u> miles per hou</u>r (\frac{miles}{hour}) so, this means that we have to know how many miles Izumi ran, given that the problem only mentioned<u> yards (110 yards).</u>

Let's convert 110 yards to miles, provided that he Izumi ran 1,760 yards in a mile.

  • 110 yards ÷ 1760 \frac{yards}{mile} = 0.0625 miles (this is the distance covered by Izumi in miles)

Let's go back again to the formula: s = \frac{d}{t}

s = \frac{0.0625 miles}{16 seconds} = 0.0039 \frac{miles}{sec}

Since, the we arrived at a miles per second unit, we have to convert it to miles per hour.

So, if a minute has 60 seconds, then an hour has 3,600 seconds.

Thus, 0.0039 \frac{miles}{sec} × 3,600 \frac{seconds}{hour} = 14.04 miles per hour (the answer)

What is the answer??
AVprozaik [17]

Answer:

HK = 20

Step-by-step explanation:

LM = (1/2) HK          {Mid point theorem}

10x - 90 = \frac{1}{2}(10x - 80) \\

2*(10x - 90) = 10x - 80

2*10x - 2*90 = 10x - 80

20x - 180     = 10x - 80                   {add 180 to both sides}

           20x  = 10x - 80 + 180

          20x  = 10x +100              {Subtract 10x from both sides from }

     20x -10x = 100

            10x  = 100

                x = 100/10

               x = 10

HK = 10x - 80

     = 10*10 - 80

     = 100 - 80

     = 20
