I would assume around 34 sorry if i’m wrong
About 172 centimeters tall.
Since he is about 3/4 his average adult height, you simply divide his current height by .75
129/.75 = 172
The correct option is: A. 80 cm³
Explanation
Diameter of the coin, 
cm.
So, the radius, 
cm.
As the coin is circular, so..
Area of each circular surface, 
cm²
Now for finding the amount of plastic for making each coin, we will find the Volume of each coin first.
As the thickness (
) of the coin is 0.5 cm, so Volume of each coin,
As you need to make a batch of 50 coins, so the total volume of 50 coins 
[Rounded up to the nearest multiple of 10 cm³]
So, the amount of plastic you will need for making a batch of 50 coins is 80 cubic centimeter.
If the x between 5 and 2 is a letter then the answer is -21
If it’s a multiplication sign then it’s 19
Answer:
x > -2
Step-by-step explanation:
First: - 9x – 15 < 3, you would want to take the 15 and add from each side.
Now it looks like: - 9x < 18
Second: You want to take the -9 and divide it from 18
Now it looks like: x < -2
Third: Chnage the less than sign into a greather than sign because we are dealing with a negative #
Now it looks like: x > -2
