Proportional Relationships:Question 8 A can of paint costs $18.75. A table shows the number of
cans of paint and the total cost of the paint. Which of the
following must be true about the data in the table?
Select one:
The number of cans is always $18.75 times the total cost.
The total cost is always $18.75 greater than the number of cans.
The ratio of the number of cans to the total cost is always $18.75.
The ratio of the total cost to the number of cans is always $18.75.

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
