5600 is 100 times larger than 56
The scale factor of the Reba's drawing is 9/84, 3/28
Step-by-step explanation:
The scale factor is the ratio between the two corresponding sides of the figure. The point worth noting in computing the scale factor is that both sides must have similar units of dimension while using for comparison purpose.
Given the scale used by Reba is 9 inches to 7 feet
Since both the units are different, we have the option to either convert inches to feet or vice versa
We proceed with converting feet to inches
We know that 1 foot equals to 12 inches. Hence 7 feet would equal 84 inches.
Now scale factor= first dimension/ corresponding dimension
Scale factor= 9/84 which can be reduced to 3/28
Your first choice is the correct answer and I am 100% sure.
A.) b = 0.7a
d) 1a = b
These two equation shows the direct variation. with the coefficient of a as the constant of variation.
y = kx ; where k is the constant of variation. y directly varies with x at the rate of k.
b = 0.7a where b represents y ; a represents x; and 0.7 represents k.
1a = b where b represents y ; a represents x ; and 1 represents k.
.075+.006x > 0.81 which inequality shows all the possible values of x?
