5 0

Answer:

yes

Step-by-step explanation:

repeating decimal. when a fraction is changed to a decimal and the remainder is not zero, a digit or a block of digits will eventually start to repeat. terminating or repeating decimal. since a rational number is a number that can be written as a fraction, every rational number can be expressed as either.

7. A coin is tossed and a day of the week is selected. What is the probability that you get tails and a day that begins with "S"
Mrrafil [7]

Answer:

1/7

Step-by-step explanation:

Lets start with the probability of flipping tails, 1/2.

Then the probability of the day starting with the letter s, 2/7.

Calculate the final probability by multiplying the two together.

\frac{1}{2}*\frac{2}{7}=\frac{2}{14}

You can simplify 2/14 down to 1/7

Answer:

Step-by-step explanation:

Remark

The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.

The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.

Solution

Sin(8) = 1817 / x           Multiply both sides by x

x*sin(8) = 1817             Divide by sin(8)

x = 1817/sin(8)

sin(8) = 0.1392

x = 1817/0.1392

x = 13055.7

Note

Watch how you do this. I would put it into your calculator as

1817

÷

sin(8)

=

If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).
