Answer:
5:4
Step-by-step explanation:
There are 12 inches in one foot, so there are 24 inches in 2 feet.
Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.
This is

Simplify it:

Think of the SS numbers as being a collection of digits. If any of the digits (say the first one for example) are 8 then all the remaining digits can be anything but 8, meaning there are 9 choices for each remaining digit. This effectively becomes an 8 digit number with the constraint that there can only be 9 choices for a digit. This means for the first digit being 8 we have 9⁸ remaining possible numbers. Since we will do this for each of the remaining digits (they each get to be 8 then we count their 9⁸ configurations) we end up with 9(9⁸) or 9⁹≈3.8742E8
First, convert that into a y=mx+b form.
Move the x to the other side so y is the only thing on the left. Since you moved it to the other side of the equal sign, be sure to make that number negative (the opposite sign)
Now… you have 4y=-3x+28
Let’s get y by itself. Since you’re multiplying 4 and y, you divide everything by 4 to get your y.
That leaves you with y=-3/4x+7.
We are looking at slope, which is your m in the y=mx+b form.
That is -3/4. The answer is the last square.

See explanation below.
The selection of drop down arrows from top to bottom should be:
5; 4; 1; 2; 3
Step-by-step explanation:
Quadrilateral with exactly ONE set of parallel sides: Trapezoid (option 5)
Parallelogram with 4 congruent (equal) sides and 4 right angles: square (option 4)
Quadrilateral with 2 pairs of parallel sides (notice no reference to angles between sides and constrain about similarity in side length - so this os the most general description): parallelogram (option 1)
Parallelogram with 4 right angles (notice no constrain about the length of the sides): rectangle (option 2)
Parallelogram with 4 congruent sides (notice there is no constrain about the angles between the sides): rhombus (option 3)
