It can increase the field because of the loops around the electromagnet like a conductor which can amplify the magnetic field making it go further

Three runners are training for a marathon. One day, they all run about ten miles, each at their own constant speed. Which of the

kotykmax [81]

Answer:

Runner 1 has the fastest pace

Step-by-step explanation:

The first one we need to find the slope

m = (y2-y1)/(x2-x1) = (40-0)/(4-0) =40/4 = 10 minutes per mile

The second is 8.5 minutes per mile

The third we need to find the slope

m = (y2-y1)/(x2-x1) = (90-72)/(10-8) =18/2 = 9 minutes per mile

ryzh [129]

Answer:

A = $16\pi$ $cm^{2}$

Step-by-step explanation:

∵ The diameter of the mug is 8 cm and using to cut out circular cookies

∴ The diameter of each circular cookie is 8 cm

∴ Its radius = 8 ÷ 2 = 4

∵ Area of the circle = $\pi r^{2}$

∴ Area = $\pi 4^{2}=16\pi cm^{2}$

If a girl in a bikini has walked 4 KM in 10 minutes, How many kilometers does she walk in 3 years?

Mashutka [201]

Answer:

631139.04 kilometers in 3 years

Step-by-step explanation:

Let x = how many kilometers she walk

y = time (minutes)

Since she walks 4km in 10 minutes.

x = 4, y = 10

(4,10)

But how many minutes if she walk only a kilometer? Divide x and y by 4.

(1,2.5)

She walks a kilometer under 2.5 minutes.

Now finding rate of changes.

$\displaystyle \large{m = \frac{10 - 2.5}{4 - 1} } \\ \displaystyle \large{m = \frac{7.5}{3} } \\ \displaystyle \large{m = 2.5}$

Since m = 2.5

and of course, the function should be proportional so the equation should be y = mx.

$\displaystyle \large{y = 2.5x }$

Since time should be minutes instead of years.

Since 3 years = 1577847.6 minutes

$\displaystyle \large{1577847.6 = 2.5x}$

Divide both sides by 2.5

$\displaystyle \large{ \frac{1577847.6}{2.5} = x} \\ \displaystyle \large{631139.04 = x }$
