<h3>What is basic algebra ?</h3>

Algebra is a branch of mathematics that facilitates the description of problems or situations into mathematical statements. It involves variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division to generate a valid mathematical statement. All branches of mathematics, such as coordinate geometry, calculus, and trigonometry, employ algebra. An elementary algebraic formula is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations on variables and constants, such as addition, subtraction, multiplication, division, etc., are done.

Find the value of z. round to the nearest hundredth
Svetradugi [14.3K]

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

\frac{30}{14}  =  \frac{z}{30}

Multiply both sides by 30;

30 \times  \frac{30}{14}  =  \frac{z}{30}  \times 30

Simplify

z =  \frac{900}{14}

z = 64.28571429

We correct to the nearest hundredthth to obtain,

z = 64.29

The correct choice is C.
