Answer:

Leah's unit rate is 16 problems per minute.

Step-by-step explanation:

To find her unit rate, we need to find how many problems she can do in 1 minute. Our current fraction is \frac{40}{2.5}. We need to divide the top and bottom by 2.5 to get the rate per minute

\frac{40}{2.5} = \frac{16}{1}

Leah's unit rate is 16 problems per minute.

Which expression gives the magnitude of the magnetic field in the region c < r2 < b (at e?
BaLLatris [955]

The electric currents and magnetic materials have an effect called magnetic field. This magnetic field is specified with its direction and magnitude. The magnitude is the strength of the field.

the magnetic field at a distance r from a long straight wire carrying current I can be calculated with the equation:

B = μ​​ ​I / 2 pi R​​

where <span>μ​​ is a constant, I is the current and R is the radius. </span>

Two bicyclists were racing toward each other when they were 98 miles apart. Three hours later they did not meet yet and the dist
lesya [120]

Let, speed of 1st bicyclist is x.

So, speed of 2nd bicyclist is x-3 .

We know, relative speed when two objects moves towards each other :

v = x + ( x-3 )\\\\v = 2x - 3

Now, distance travelled in 3 hours is (98-2) miles .

So,

2x-3 = \dfrac{96}{3}\\\\2x - 3 = 32\\\\2x = 35\\\\x = 17.5\ mph

Therefore, speed of bikes are 17.5 mph and 14.5 mph.

Hence, this is the required solution.
