<h3>
Answer: Choice D. 8:9</h3>
Work Shown:
16 boys: 18 girls
16:18
16/2:18/2
8:9
I divided both parts of the ratio by the GCF 2 in order to reduce from 16:18 to 8:9. For every 8 boys there are 9 girls.
Let x and y be your two consecutive whole numbers
x < sqrt(142) < y
x^2 < 142 < y
So, we are looking for x and y such that x^2 < 142 and y^2 > 142.
The closest squared number to 142 is 144 = 12^2.
Next is 11^2 = 121.
11 and 12 are consecutive.
11^2 = 121 < 142 < 144 = 12^2
Thus, 11 and 12 are your numbers
Solving the equation we get:

Step-by-step explanation:
We need to solve the equation: 
Solving:


Taking LCM of 9 and 4 we get 36




So, solving the equation
we get 
In the first blank, in denominators we get 36 and in the second black we get 
So, answer is:

Answer:
A: Designing the layout.
Step-by-step explanation:
Remember this: Geometry uses shapes.
Let's use the process of elimination.
D is eliminated because it does not use shapes.
C is eliminated because it uses numbers, not shapes.
B is eliminated because it uses science, not math or shapes.
A uses shapes in order to design a structure.
