While on a road trip, Steve drove 300 miles in 5 hours. After stopping for gas, he drove an additional 120 miles in 2 hours. Doe
bija089 [108]

Answer:

The given situation is in direct variation.

The dependent variable is the distance covered and the independent variable is the number of hours.                

Step-by-step explanation:

We are given the following information in the question:

Steve drove 300 miles in 5 hours.

After stopping for gas, he drove an additional 120 miles in 2 hours.

We calculate the ratios and if these ratios are equal then, we can say that the situation represent a direct variation.

For direct variation, the equation is of the form y = kx that is , we can write,

\displaystyle\frac{y}{x} = k

To check the ratio:

\displaystyle\frac{300}{5} = \frac{300+120}{5+2} =\frac{420}{7} = 60

Thus, the given situation is in direct variation.

The dependent variable is the distance covered and the independent variable is the number of hours.

Can't figure out this problem can anyone help if so thank you
Virty [35]

Answer:

10th term of the sequence = 0.537

Step-by-step explanation:

First three terms of the sequence are → 5, 4, \frac{16}{5}..........

Ratio of 2nd and 1st term of the sequence = \frac{4}{5}

Ratio of 3rd and 2nd term of the sequence = \frac{\frac{16}{5} }{4}

                                                                        = \frac{4}{5}

Therefore, ratio between every successive term to the previous term is common.

Common ratio 'r' = \frac{4}{5}

First term of the sequence 'a' = 5

nth term of a geometric sequence = a(r)^n

Therefore, nth term of the given term will be  T_n=5(\frac{4}{5})^n

Now we have to find the 10 term of the given sequence.

For n = 10,

T_{10}=5(\frac{4}{5})^{10}

      = 0.53687

      ≈ 0.537

Therefore, 10th term of the sequence is 0.537

Find the size of angle q if it is five times it's supplement​
tino4ka555 [31]

Answer:

<em>q =</em> 150

Step-by-step explanation:

Supplementary angles are angles that form a straight line and have a sum of 180 degrees, e.g. 120 and 60. If its supplement is thirty, and angle <em>q </em>is five times its supplement, it's 150. We know this is correct because 150 + 30 = 180, which is what we need for a supplementary angle.

What is the reference angle of -139 degrees
katrin [286]

41º

1) Since we want to find the reference angle for a -139º angle, we need to resort to the following formula

Reference\:Angle\:\:Quadrant\:III=180^{\circ}-139^{\circ}=41^{\circ}

2) Note that a -139 angle is in quadrant III, since negative angles are clockwise oriented

3) Thus the Reference Angle is 41º
