Mr. Hershman has purchased a farm that is in the shape of a rectangle. The dimensions of the piece of land are 4.74.7 km by 2.58

Gre4nikov [31]

Answer:

Area in square kilometers equals $12.126km^{2}$

Area in hectares equals 1212.6 hectares

Step-by-step explanation:

We know that area of rectangle is length times the breadth.

Using the given values we have

$Area=length\times breadth\\\\\therefore Area =4.7km\times 2.58km\\\\Area=12.126km^{2}$

Thus he bought land of area $12.126km^{2}$

We know that 1 hectare = $0.01km^{2}$

Thus 12.126 $km^{2}$ = 12.126/0.01 hectares

Area in hectares equals 1212.6 hectares

Solve the formula for the indicated variable D=ABC for A

vfiekz [6]

The value of $A=\dfrac{D}{BC}$ .

Step-by-step explanation:

Given that,

An expression, $D=ABC$

To find,

Solve the expression for A.

Solution,

We have,

$D=ABC$

Dividing both sides of the given equation for $BC$ . So,

$\dfrac{D}{BC}=\dfrac{ABC}{BC}\\\\A=\dfrac{D}{BC}$

So, the value of A is, $A=\dfrac{D}{BC}$ .

An airplane heading due east has a velocity of 210 miles per hour. A wind is blowing from the north at 38 miles per hour. What i

Nimfa-mama [501]

Answer:

The resultant velocity of the airplane is 213.41 m/s.

Step-by-step explanation:

Given that,

Velocity of an airplane in east direction, $v_1=210\ mph$

Velocity of wind from the north, $v_2=38\ mph$

Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.

We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :

$v=\sqrt{v_1^2+v_2^2}$

$v=\sqrt{(210)^2+(38)^2}$

v = 213.41 m/s

So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.

Find the solution set of the inequality:<br> -3x + 8 < 15

telo118 [61]

Hello from MrBillDoesMath!

Answer:

x > -7/3

Discussion:

-3x + 8 < 15 => add 3x to both sides

(-3x + 3x) + 8 < 15 + 3x => (-3x + 3x) = 0

8 < 15 + 3x => subtract 15 from both sides

8-15 < 3x => 8 - 15 = -7

-7 < 3x => divide both sides by 3

-7/3 < x

Thank You,

MrB
