Question

1. what kind of angle measures less than 90 degrees? draw one. 14. order these decimals from least to greatest: 6.41 6.4 6.04 6.341 16. write nine and five thousandths in standard form.

Explanation:

Question 12

An angle less than 90 degrees is defined as an acute angle.

Step1: Compare the integer parts

All decimals have an integer part of 6.

Step2: Compare the tenths place

• For \(6.04\), the tenths place is \(0\).
• For \(6.341\), the tenths place is \(3\).
• For \(6.4\) (which is \(6.400\)) and \(6.41\), the tenths place is \(4\).

Since \(0<3 < 4\), \(6.04\) is the smallest.

Step3: Compare \(6.4\) and \(6.41\)

\(6.4 = 6.400\) and \(6.41\). Comparing the hundredths place (\(0<1\)), so \(6.4<6.41\)

Step1: Analyze the whole - number part

The whole - number part is \(9\).

Step2: Analyze the decimal part

Five thousandths is written as \(0.005\) (since \(5\times\frac{1}{1000}=0.005\))

Step3: Combine the whole - number and decimal parts

\(9 + 0.005=9.005\)

Answer:

Acute angle.
