Steffie makes a scale drawing for a crate with a scale factor of 1:3. The dimensions of her scale drawing are 15
inches long by 12 inches wide. The builder creates a scale
drawing of the crate with a scale factor of 1:9.
What are the dimensions of the builder's scale drawing?
A. The length is 36 inches and the width is 45 inches.
B. The length is 4 inches and the width is 5 inches.
C. The length is 45 inches and the width is 36 inches.
D. The length is 5 inches and the width is 4 inches.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

hi there!

the answer will be d: 2

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
