- Interpretation of graphs and 10.

- A cargo consists of wheat and cotton.

- A ship has 400 tons of wheat and 100 tons of cotton.

- 35 babies were born at the hospital.

- There are 67 g of pure gold and 35 g of pure zinc in the alloy.

- Your answer should be sent to the ones place.

- A number can be written in scientific notation.

- In chemistry, we often work with numbers that are small.
- The width of a human hair is about 0.000 008 m. When it helps make the places easier to count, we add spaces between sets of three digits.

- The number 2400 is written in scientific notation.

- Humans have an average of 105 hairs on their heads.

- Each hair is about 10 m wide.

- The power of 10 is written as 103 because we moved the decimal point three places to the left.

- The power of 10 is positive.

- 0.000 86 is written in scientific notation.
- Theficient is obtained by moving the decimal point to the right.
- The power of 10 is a negative 4 because the decimal point is moved four places to the right.
- The power of 10 is negative when a number less than 1 is written.

- The powers of 10 are used to keep track of the number's decimal point.

- You can get a coefficient that is at least 1 but less than 10 by moving the decimal point.
- For a number greater than 1, the decimal point is moved to the left three places.

- As a power of 10, express the number of places moved.
- The power of 3 is given by moving the decimal point three places to the left.

- The product of the coefficients should be written.

- You can get a coefficient that is at least 1 but less than 10 by moving the decimal point.
- The coefficients of 1.6 are given by moving the decimal point to the right five places.

- As a power of 10, express the number of places moved.
- The power of negative 5 is given by moving the decimal point five places to the right.

- The product of the coefficients should be written.

- The EE or EXP key can be used to enter a number.

- You can enter the power 10 by pressing the EE or EXP key.
- To enter a negative power of 10, you have to use the calculator.

- When a calculator answer appears in scientific notation, the coefficients are shown as a number that is at least 1 but less than 10, followed by a space or E and the power of 10.

- Write the coefficient value, write * 10, and use ber in scientific notation on your calculator if you want to describe how you enter a num express this display.

- The appropri ate keys are used to convert a number on a calculator.
- The number 0.000 52 is entered, followed by pressing the 2nd or 3rd function key and the SCI key.
- The calculator display shows the scientific notation as a coefficient and power of 10.

- A number can be written in scientific notation.

- There is a clear, sweet-tasting, thick liquid victim's blood.
- The quan that is odorless mixes with water.
- It is easy to get since the tests show that it is used in automobiles and brake fluid.
- The initial symptoms of poisoning are similar to 125 g of ethylene glycol.

- The container was found in the home of the victim.
- 1.5 g of ethylene glycol is the body mass of the person.

- Your answer should be sent to the ones place.

- 75 g could be fatal for a person over 50 lbs.

- The husband of the victim had 1.5 g of ethylene glycol per 1000 g.

- A hypothesis may become a theory after repeated successful experiments.

- Strategies that are effective for learning can be identified.

- A number can be written in scientific notation.
