Range is the difference between the highest and lowest number. 67 minus 19 is 48

range: 48

Range is the greatest number minus the smallest number

The greatest number is 67
The least number is 19

67 - 19 = 48

48 is your range

hope this helps

The length of a rectangle is 1 ft less than twice the width, the area of the rectangle is 21 ft squared. What’s the length

guapka [62]

Answer:

The length of the rectangle is 6 feet

Step-by-step explanation:

Given as :

The length of rectangle is 1 feet less than twice the width

So, let The width of rectangle = w feet

The length of rectangle = ( 2 w - 1 ) feet

The area of the rectangle = 21 feet²

Now,

∵ The area of the rectangle = length × width

Or, 21 feet² = ( 2 w - 1 ) feet × w feet

or, 21 = 2 w² - w

or, 2 w² - w - 21 = 0

or, 2 w² + 6 w - 7 w - 21 = 0

or , 2 w ( w + 3 ) - 7 ( w + 3 ) = 0

or, ( w + 3 ) ( 2 w - 7 ) = 0

So, w = - 3 feet , $\frac{7}{2}$ feet

here we consider only positive value of w i.e $\frac{7}{2}$ feet

∴ The length of rectangle = ( 2 w - 1 ) feet

or, The length of rectangle = 2 × $\frac{7}{2}$ - 1

Or, The length of rectangle = 7 - 1 = 6 feet

Hence The length of the rectangle is 6 feet , Answer

You Fit Gym is equidistant and collinear from Target and Pizza Hut. Target is located at point (-17, 17) and You Fit Gym is at (

Paul [167]

Answer:

The coordinates of the Pizza Hut is (6,-11)

Step-by-step explanation:

Gym is equidistant and collinear from Target and Pizza Hut.

T (-17, 17) : $(x_1,y_1)$

G (-5.5, 3) : (x,y)

P : $(x_2,y_2)$

Mid point formula ; (x,y) is on mid point on line formed by joining points $(x_1,y_1)$ and $(x_2,y_2)$

m = 1, n = 1

$x=\frac{x_1+x_2}{2}$

$-5.5=\frac{-17+x_2}{2}$

$-11=-17+x_2$

$x_2=17-11 = 6$

$y=\frac{y_1+y_2}{2}$

$3=\frac{17+y_2}{2}$

$6=17+y_2$

$y_2=-17+6 = -11$

The coordinates of the Pizza Hut is (6,-11)
