To find the area of the Canadian field, you need to multiply the area of the American football field by 3,550.

Area of Canadian field = Area of American field x 3,550
= 6.4 x 10^3 x 3,550

To multiply two numbers in scientific notation, you multiply their coefficients and add their exponents.

6.4 x 10^3 x 3,550 = 22.72 x 10^6

The area of the Canadian field is 22.72 x 10^6.
an american football field has the area of 6.4 x 10^3 and a canadian feild is 3,550 larger what is the area of an cannaidian feild use scientific notation to 2 decimal places 8th grade pre algebra
answer: ___x10^3
To find the area of the Canadian field, we need to add 3,550 to the area of the American football field.

Area of Canadian field = Area of American field + 3,550
= 6.4 x 10^3 + 3,550.

We can't add a number in scientific notation directly with a regular number. So, we need to convert the Canadian field area into scientific notation using the given format (to 2 decimal places).

3,550 can be written in scientific notation as 3.55 x 10^3.

Now, we can add the two numbers in scientific notation.

6.4 x 10^3 + 3.55 x 10^3 = (6.4 + 3.55) x 10^3
= 9.95 x 10^3.

Therefore, the area of the Canadian field is 9.95 x 10^3.
an american football field has the area of 6.4 x 10^3 and a canadian feild is 3.55x10^4 larger what is the area of an cannaidian feild use scientific notation to 2 decimal places 8th grade pre algebra
answer: ___x10^3
To find the area of the Canadian field, you need to add 3.55 x 10^4 to the area of the American football field.

Area of Canadian field = Area of American field + 3.55 x 10^4
= 6.4 x 10^3 + 3.55 x 10^4.

To add two numbers in scientific notation, the coefficients must have the same exponent. In this case, you need to convert 6.4 x 10^3 into scientific notation with an exponent of 4.

6.4 x 10^3 can be written as 6.4 x 10^4 (by multiplying the coefficient by 10).

Now, let's add the two numbers in scientific notation.

Area of Canadian field = 6.4 x 10^4 + 3.55 x 10^4
= 9.95 x 10^4.

Therefore, the area of the Canadian field is 9.95 x 10^4.
an american football field has an area of 6.4 x 10^3 square yards a canadian football feild is 3350 square yards larger what is the area of a canadian football field write your answer in scientific notation to 2 decimal places
answer:___ x 10^3
To find the area of the Canadian football field, you need to add 3350 square yards to the area of the American football field.

Area of Canadian field = Area of American field + 3350 square yards
= 6.4 x 10^3 square yards + 3350 square yards.

To add the two numbers, we need to convert them into scientific notation with the same exponent.

6.4 x 10^3 square yards can be written as 6.4 x 10^3 square yards.

3350 square yards can be written as 3.35 x 10^3 square yards (by dividing the coefficient by 1000).

Now, let's add the two numbers in scientific notation.

Area of Canadian field = 6.4 x 10^3 square yards + 3.35 x 10^3 square yards
= (6.4 + 3.35) x 10^3 square yards
= 9.75 x 10^3 square yards.

Therefore, the area of the Canadian football field is 9.75 x 10^3 square yards.
a human hair has a diameter of about 4 x 10^-3 inches. a finger nail is about 0.011 inches thicker how thick is a fingernail write your answer as a decimal to 3 places
To find the thickness of a fingernail, you need to add the diameter of a human hair to the additional thickness of a fingernail.

Thickness of fingernail = Diameter of human hair + Additional thickness of fingernail
= 4 x 10^-3 inches + 0.011 inches.

To add the two numbers, we simply add the coefficients while keeping the same exponent.

Thickness of fingernail = 4 x 10^-3 inches + 0.011 inches
= 0.004 inches + 0.011 inches
= 0.015 inches.

Therefore, the thickness of a fingernail is 0.015 inches, to 3 decimal places.
