The adult height of a male is about 1.19 times his height at age 12. The adult height of a female is about 1.07 times her height at age 12. Predict how tall is Miguel and Ramona will be as adults if Miguel is 1.5 m and Ramona is 1.6 m. Predict how tall you will be.

Pls help me I don't understand how to get how yall I will be and I think I did the first part right but not too sure.

Answers

If you are 12 years old, just measure your own height, then multiply your height by 1.19 if you’re a male, or 1.07 if you’re a female.

The height of Miguel as an adult is 1.785 m.

The height of Ramona as an adult is 1.712 m.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The adult height of a male is about 1.19 times his height at age 12.

The adult height of a female is about 1.07 times her height at age 12.

Now,

Miguel:

Height at the age of 12 = 1.5 m

The height when he is an adult.

= 1.19 x 1.5

= 1.785 m

Ramona:

Height at the age of 12 = 1.6 m

The height when she is an adult.

= 1.07 x 1.6

= 1.712 m

Thus,

The height of Miguel and Ramona as adults are 1.785 m and 1.712 m.
