An athlete training for the Olympics women's each lap for a 4 lap race in the following times: 54.73, 54.56, and 54.54 seconds.

natita [175]

Answer:

The total time it takes her to swim the four laps is 3.65 minutes.

Step-by-step explanation:

Here, according to the given data:

The time taken to complete 1st lap = 54.73 seconds

The time taken to complete 2nd lap = 54.56 seconds

The time taken to complete 3rd lap = 54.32 seconds

The time taken to complete 4th lap = 54.54 seconds

Now, the TOTAL TIME taken to swim all 4 laps = SUM OF ALL 4 TIMES

= (54.73 + 54.56 + 54.32 + 54.54) seconds

= 219.35 Seconds

Now, 60 seconds = 1 minute

⇒ 1 seconds = 1/60 minute

⇒219.35 seconds = 219.27 x (1/60) minutes = 3.6558 minutes

Hence, the total time it takes her to swim the four laps is 3.65 minutes.

Which lengths make sense for possible values of b

Lerok [7]

The first condition is for the perimeter of the equation so:

$P=2a+b=15.7$

Now the secon condition is that the sum of two sides should be:

$\begin{gathered} a+b>b \\ b+b>a \end{gathered}$

so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5

So in the first equation will be:

$\begin{gathered} 2a+0.5=15.7 \\ 2a=15.2 \\ a=7.6 \end{gathered}$

So the condition:

$\begin{gathered} b+b>a \\ 0.5+0.5>7.6 \end{gathered}$

this is false, so the solution is

Write 83 as a sum of tens and ones

Hoochie [10]

Well,

We can see that there are 8 10's and 3 1's. So we can write 8 10's followed by 3 1's and join them with addition symbols.

83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1
