Answer:

39.9km a day

Step-by-step explanation:

Add up the four kilometers cycled and you should get 159.6km cycled in total.  Divide that number by 4 to get 39.9km as a result.  So she's wrong.

Answer:

39.9

Step-by-step explanation:

Because he cycled 4 days and the distances for each days are 32.3 km, 38.7 km, 43.5 km and 45.1 km. The total distance should be,

Total = 32.3 km + 38.7km + 43.4km + 45.1km\\\\= 159.6km\\

Now the average should be,

Avg = \frac{159.6 km}{4}\\= 39.9 km

This is of course less than 40km and you can told her that she's wrong. And, this is true only when the data of each day is accurate and not rounded so that actual total is relatively more than the one I have calculated.

HDTV screens usually have a width-to-heigh ratio of 16:9. Which screen dimensions are in the same proportion?
Lana71 [14]

Answer:

4: 3

Step-by-step explanation:

In this case, we have that there is a relationship between width and height, which is 16: 9, which means that any screen that has the same ratio would be an identical screen.

How would we do this? it must either be raised to a power or rationalized on both sides of the ratio.

If we raise to a power, it would give very large dimensions for an HDTV, therefore, it is best to remove the square root on both sides, since it has more common values for a TV.

\sqrt{16} :\sqrt{9}

4: 3

Therefore, a 4: 3 screen is a good choice for an HDTV with the same ratio.

I have 6 thousands 12 tens 9 hundreds 10 ones and 3 tenths what number am i
mixer [17]

Here let us first write the value of each number:

6 thousands means 6*1000=6000.

9 hundreds means 9*100=900.

12 tens means 12*10 =120

10 ones means 10*1 =10

3 tenths means 3/10 =0.3

Now we just have to add all these values to get the final number.

adding 6000 + 900 +120 +10 +0.3 = 7030.3

So the final number is 7030.3

NNADVOKAT [17]

Answer:

x=\frac{-7+-\sqrt{37} }{6}

Step-by-step explanation:

This (±) goes between the -7 and \sqrt{37}

3x^{2} +7x+1=0

ax^{2} +bx+c

-b ± \sqrt{b^2-4ac}/2a

-7 ± \sqrt{(7)^2-4(3)(1)}/2(3)

-7 ± \sqrt{49-12}/6

-7 ± \sqrt{37}/6
