Answer:

4680 km / hour

Step-by-step explanation:

You can do this with a method called dimensional analysis. (I think you should check the speed. Are you sure it is that fast?)

\frac{1300 m}{sec}*\frac{1 km}{1000 m} * \frac{3600 sec}{1 hr}\\

1.3 * 3600 = 4680 km/hour

Lerok [7]

Answer:


Step-by-step explanation:

The image on the right is not the answer. It is reflected across the y axis. equations and the inverses are reflections of each other across the line y = x. So that lets out the middle one as well which looks to be reflected across y = - x

That only leaves the left image which is the correct answer.

Ricky ate 2 soft tacos, and 4 of his friends ate s soft tacos. If there were 18 2 points
shtirl [24]

Answer:

Each friend ate 4 tacos.

Step-by-step explanation:

"4 of his friends ate s tacos" is unclear. I assume it should be

"4 of his friends ate s tacos each."

total tacos = 2 + 4s = 18

4s = 16

s = 4

His four friends ate a total of 16 tacos, each friend eating 4 tacos.

Ricky's reason, i.e., that 6s = 18, is incorrect.

6s = 4s+2s, where 4s is what his friends ate in total.

That implies that Ricky ate 2s tacos, instead of 2 tacos. If 2s = 2 then s = 1, but then 6s ≠ 18.

Line CD passes through points C(3, –5) and D(6, 0). What is the equation of line CD in standard form?
FinnZ [79.3K]
Slope of the line = (0- -5) / 6-3) = 5/3

in point slope form the equation is

y - 0 = 5/3( x - 6)

y = 5/3x - 10

multiply through by 3:-
3y = 5x - 30
In Standard form this is

5x - 3y = 30   Answer

icang [17]

Answer:

Step-by-step explanation:

w / h = u / HG

w = 8

h = 48

u = 5

lets use  h / w  = HG / u   this is the same relationship but looks easier to me

48/8 = HG / 5

6 = HG / 5

6 * 5 = HG

30 = HG

not too tuff... when you set the relationship so it's easiest  :)

and yes.. we cold have swapped the fractions and done it the other way and gotten the same answer.. but maybe with a bit more algebra.. and... avoid extra algebra ... that's where the mistakes can be made  :P
