Answer:

D. 6 21/50

Step-by-step explanation:

In order to find a fraction in lowest terms, we first have to actually change the number 6.42 into a fraction.

0.42 can also be written as the fraction 42/100.

To simplify the fraction, we just have to look for a number that both the number on the top (numerator) and number on the bottom (denominator) can be divided by.

Well, both 100 and 42 can be divided by 2.

100 divided by 2 = 50

42 divided by 2 = 21

Now we have the fraction 21/50

21 and 50 do not have a number they can both be divided by, so it is in lowest terms.

Now, just add it back to 6.

The crose harbor tunnel is about 1900m long . it is a little less than --------- km.
Volgvan
If you would like to convert meters to kilometers, you can calculate this using the following step:
1 meter = 0.001 kilometers
1900 m = 1900 * 0.001 km = 1.9 km

If the tunnel is about 1900 m = 1.9 km long, then this is a little less than 2 km, because 1.9 km < 2 km.

Answer:

A. x^2 = (4x - 1)^2 + (6x + 7)^2

Step-by-step explanation:

The question seems to be incomplete. However, we'll make the following assumption.

Opposite = 6x + 7

Adjacent = 4x - 1

Hypothenuse = x

Pythagoras theorem states that:

Hypothenuse^2 = Opposite^2 + Adjacent^2

Substitute values for Hypothenuse, Opposite and Adjacent.

This gives

x^2 = (6x + 7)^2 + (4x - 1)^2

or

x^2 = (4x - 1)^2 + (6x + 7)^2

From the list of given options.
