Answer:

  A)  33 3/4°

Step-by-step explanation:

  supplement of 146 1/4° = 180° -(146 1/4)°

  = (180° -146°) -1/4° = 34° -1/4°

  = 33 3/4° . . . . supplement of the given angle

Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long,
AysviL [449]

We have been given that Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long. We are asked to find the length of chain of bacteria in centimeters.

We know that 1 millimeter is equal to 0.1 centimeter.

To convert 10 milllimeters into centimeters, we will multiply 10 by 0.1.

\text{Length of bacteria in cm}=10\text{ mm}\times \frac{0.1\text{ cm}}{\text{1 mm}}

\text{Length of bacteria in cm}=10\times 0.1\text{ cm}

\text{Length of bacteria in cm}=1\text{ cm}

Therefore, the chain of the bacteria is 1 cm long.
