Answer: 80 sq. ft

Step-by-step explanation:

Company A’s charges can be represented by the equation: 10m + 250

Company B’s charges can be represented by the equation: 12m + 90

To find when the square feet got which they have the same amount, I will set them equal to each other and solve for it.

10m+250=12m+90

-10m -10m

250=2m+90

-90 -90

160=2m divide both side by 2

80=m

For 80 square feet, both companies charge the same amount.

RoseWind [281]

Answer:

Front: 33 ft

Back: 66 ft

Step-by-step explanation:

Let w be the width of the front yard

½[w + 2w]×2w = 3300

3w² = 3300

w² = 1100

w = 33.1662479036

w = 33 ft

2w = 66 ft

Given that the area immersed in the gap is changing as the coil enters the gap, what is the correct expression of Faraday's Law
zvonat [6]

Complete Question

The complete question is  shown on the first uploaded image

Answer:

 The  induced emf  is  \epsilon   =  B *  l * v

Step-by-step explanation:

Now assume that the coil is  shaped as a rectangle with length  l and  width b

   This  implies that the area of the coil is  A=  l *  b

Now when it enter into the uniform magnetic field the magnetic flux due to its movement as stated in the question is mathematically represented as

        \phi =  BA

=>    \phi =  B  (l* b  )

Now the induced emf is  mathematically represented as

          \epsilon   =  \frac{d\phi}{dt}

=>       \epsilon   =  B *  l  [\frac{db}{dt} ]

The  l  is constant because as it glides to and from the magnetic field it is displaced along the horizontal plane while along the vertical plane it is constant

Here  \frac{db}{dt}  = v

Where is the velocity the glide (i.e the coil)

So

       \epsilon   =  B *  l * v

A dentist wants to find out how often her patients floss their teeth. Which samples are biased? Check all that apply. all her pa
ArbitrLikvidat [17]

Answer:

all her patients patients with no cavities

patients younger than 18

every patient with braces

Step-by-step explanation:

when a sample is selected in a manner that some elements, in this case patients, of population have higher or lower probability of sampling then that sample is biased.

From given case, all the following are biased samples

all her patients patients with no cavities

patients younger than 18

every patient with braces

because they are non-random sample of a population in which all other elements were not equally likely to be chosen!

Which graph shows the lowest cost per square foot for a new home?
aliina [53]

We are given following coordinates in given graphs (1000,12000), (1500, 16000), (500 , 8000) , (2000, 18000).

Let us discribe each given coordinate and cost per square foot area for each coordinate (in each graph).

1st (1000,12000) : represnts 1000 square foot area cost $12000.

Cost per square feet = 12000/1000 = $12.

2nd (1500, 16000) : represnts 1500 square foot area cost $16000.

Cost per square feet = 16000/1500 = $10.67.

3rd (500 , 8000)  : represnts 500 square foot area cost $8000.

Cost per square feet = 8000/500 = $16.

4th (2000, 18000) : represnts 2000 square foot area cost $18000.

Cost per square feet = 18000/2000 = $6.

Therefore, 4th graph with (2000, 18000) coordinate shows the lowest cost that is $6 per square foot for a new home.
