8 kilometers in one hour

Step-by-step explanation:

4:30/4

30 divided by 4

7.5

4 divided by 4

7.5 minutes to 1 kilometer

since there are 60 minutes in a hour

Convert these decimals into fractions 0.49 and 4.542
Anuta_ua [19.1K]

Answer:

0.49 = \frac{49}{100}

4.542 = 4 \frac{542}{1,000}

Step-by-step explanation:

0.49 is equivalent to 49/100 because 0.49 represents the hundredth place.

4.542 is equivalent to 4 542/1,000 because .542 is representing the thousandths place, and the 4 is a whole number.

Hope this helps!

Answer:

There are 604,800 possible permutations.

Step-by-step explanation:

The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this question:

7 digits from a set of 10(10 digits to 0-9). So

P_{(10,7)} = \frac{10!}{(10-7)!} = 604800

There are 604,800 possible permutations.

Which image shows a plane slicing a double-napped cone to produce a hyperbola?<br><br> Answer is D
Butoxors [25]

The <u>second image</u> in the diagram is a hyperbola. As can be seen, the plane cutting the cone can be at any angle but never equal to the slant angle of the cone. This has a very important implication. The plane cuts both cones of the double-napped cone. The third double-napped cone of Figure 3 shows two hyperbolas.
