Find the unit rate.kilometer in17hourEnter the correct answer in the box.
Nuetrik [128]

The question asks for the unit rate when 1/4 of a kilometer is covered in 1/3 of an hour.

Recall that rate is the quotient of two quantities. In our case the numerator is the distance (1/4) of a kilometer, and the denominator is the time: 1/3 of an hour.

So, we perform the following division of fractions:

1/4 diided by 1/3 which is the same as: 1/4 times 3/1 = 3/4

and since we are asked for the UNIT rate, we do the actual division:

The unit rate is 0.75 km per hour.

Part one: Sequence and Series
ASHA 777 [7]

Answer:

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a + (n - 1)d

where a is the first term and d the common difference

Here a = 13 and d = - 2.5, thus

a_{29} = 13 + (28 × - 2.5) = 13 - 70 = - 57

Find the value of x in the triangle shown below 3.5 4 3.5 x• 55•
Dvinal [7]

Answer:

Step-by-step explanation:

Since this is not a right triangle, we will use the Law of Sines. For us that looks like this:

\frac{sin55}{3.5} =\frac{sinx}{4} and cross multiply to get

4sin55 = 3.5sinx and solve for sinx:

sinx=\frac{4sin55}{3.5} so

sinx = .9361737 Use the 2nd button on your calculator and the sin button to find that the angle

x = 69.4°. Not sure how you need it rounded. It's actually 69.4186°
