Lara ran 3/4 of a mile and walked 3/8 of a mile.how much farther did Lara run than walk simlify

djverab [1.8K]

Lara ran 3/4 so
3/4 = 6/8

Lara walked 3/8

Find the diffrence:

6/8 -3/8 =3/8

So she run 3/8 mile farther than walk

A factory is to be built on a lot measuring 210 ft by 280 ft. A local building code specifies that a lawn of uniform width and e

Tresset [83]

Answer:

Width of lawn = 35 ft

Dimensions of factory = length: 210 ft, width: 140 ft

Step-by-step explanation:

The total area of the lot can be calculated as:

$A_{lot} = 210 * 280\\A_{lot} = 58800 ft^{2}$

Since, the area of factory should be equal to area of lawn:

$A_{lot} = A_{factory} + A_{lawn}\\58800 = 2 A_{factory or lawn}\\\\A_{factory or lawn} = \frac{58800}{2}\\A_{factory or lawn} = 29400 ft^{2}$

Now, let 'x' be the width of lawn, the dimensions of factory can be written as:

$(210-2x)\\(280-2x)\\$

Since, area is equal to length x width:

$(210-2x)*(280-2x) = 29400\\Simplifying:\\210*280 - 210*2x - 2x*280 + 4x^{2} = 29400\\58800 - 420x - 560x +4x^{2} = 29400\\4x^{2} - 980x +58800 = 29400\\4x^{2} - 980x + 29400 = 0\\$

Divide whole equation by 4,

$x^{2} - 245 + 7350 = 0\\$

Solving above quadratic equation, we get,

$x = 210\\x = 35\\$

x = 35 seems realistic width of the lawn.

Now, finding the dimension of factory:

$(210-2x) = 210 - 2(35) = 140 ft\\(280-2x) = 280 - 2(35) = 210ft$

We can also reconfirm the area of factory by multiplying the above two lengths:

140 * 210 = 29400 ft

Whcih of these equations define y as a nonlinear function of x?

dexar [7]

Answer:

hello :

note :

the linear function of x have equation : y = ax + b

correct answer is : A) and C) and E)

A) : 3y = 2x -15

y = (2/3)x -15/3

y = ( 2/3)x -5 ..... when : a = 2/3 and b = -5

B) : 5(x+y)=-25

x + y = - 5

y = - x -5 ...... when : a = -1 and b = -5

C) y = 1

y = 0x +1 .....when : a = 0 and b = 1
