Answer:
A) 46 mph
Step-by-step explanation:
<em>Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.</em>
Distance = 354 miles
Time = 9: 50 am to 5: 30 pm
Time = 7 hours 40 minutes
<em>Step 2: Convert time to hours</em>
1 hour = 60 minutes
40 minutes = 60/40 = 2/3 hours
<em>Step 3: Find the speed</em>
Speed = Distance/Time
Speed = 354/7 + 2/3
Speed = 1062/23
Speed = 46.17 miles per hour rounded off to 46 mph
Therefore, A is the correct answer.

Answer:
x = 12
Step-by-step explanation:
39/26 = 1.5
18/x = 1.5
18 = 1.5x
18/1.5 = x
12 = x
Well 1 is in the ones place so its 1
.848 is 848 thousandths so it would be 1
Um hmm let me get my calculate <span />
Answer:
Angle A is about 61.9 degrees
Step-by-step explanation:
To find the measure of an angle, we can use inverse trigonometry. To find A, we can use the formula A=sin^-1(opposite/hypotenuse).
The side opposite of angle A is 15, and the hypotenuse of the triangle is 17. We can plug in the numbers into the calculator to get:
A= sin^-1 (15/17)
A= 61.9275
We round to 61.9.
