The distance between Chicago and Cleveland is
lozanna [386]

Answer:

The average speed on this trip was 46.15 mph. The correct option is A.

Step-by-step explanation:

In order to calculate the average speed, we need to apply the following formula:

v_{avg} = \frac{\text{distance}}{\text{time}}

We were given the distance between the two cities in miles, therefore we can directly apply it to the expression. Although the time was given in the hh:mm 12 h format and we need a diference in hours, so we will convert that as shown below:

\text{time departure} = 9 + \frac{50}{60} = 9.83 \text{ h}

\text{time arrival} = 12 + 5 + \frac{30}{60} = 17.5

The elapsed time of the trip is the difference between these:

\text{time} = 17.5 - 9.83 = 7.67 \text{ h}

We can now apply it to the formula:

v_{avg} = \frac{354}{7.67} = 46.15 \text{ mph}

The average speed on this trip was 46.15 mph. The correct option is A.

What is the solution of log(4-3) = log(17-41)?<br> O4<br> O 5<br> O 15<br> O 20
borishaifa [10]
<h3>Answer: Choice A) 4</h3>

Explanation:

The rule is that if log(A) = log(B), then A = B

Using this idea, we can then say,

log(t - 3) = log(17 - 4t)

t - 3 = 17 - 4t

t+4t = 17+3

5t = 20

t = 20/5

t = 4

tresset_1 [31]

Answer:

170

Step-by-step explanation:

The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

wx = 2(42x + 1)

We can add up that and the other arcs to 360.

2(42x + 1) + 29x - 1 + 65x + 3

84x + 2 + 29x - 1 + 65x + 3 = 360

178x + 4 = 360

178x = 356

x = 2

Plug in 2 for WX.

84(2) + 2 = 170
