During a science lab, Alyssa learned that the approximate radius of a grain of sand is 1.2 x 10^-3 inches. Represent this value in standard notation.

Step-by-step explanation:

Standard Form means to change it into a decimal that is not scientific notation.

The question you have given is

.0012

The way you think of it is the number of zeros is numerically 1 less than the power when the power is minus.

john earns $14.00 for two hours of work.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
