Hello!
Let's write this as an equation below.
310/3+d=295/d
As you can see, we can cross-multiply this proportion giving us the equation below.
310d=295(3+d)
310d= 295d+885
Now, we subtract 295d from both sides.
15d=885
Now we divide both sides of the equation by 15.
d=59
Therefore, Dana travels 59 mph.
I hope this helps!
Answer:
Para poder definir los radianes, es necesario introducir el concepto de ángulo central. Un ángulo central es un ángulo cuyo vértice está en el centro de un círculo. En el círculo siguiente, el centro es el punto O, la longitud del radio es r, y es el ángulo central y 30 grados equivale a vil.
Step-by-step explanation:
The answer would be "both groups show about the same average time"
What you need to do is make each fraction into a decimal and then put them in order from least to greatest.
7/12=0.583
1/8= 0.125
5/16= 0.3125
5/6= 0.83
The order for this is 0.3125, 0.125, 0.583, and 0.83. So the answer is last option
