Answer:
(11 x 2) - 7 + 4
Is your algebra expression.
To determine the fraction of her classmates with dogs as pets, we simply multiply the two given fractions based from the survey.
Pets = (2/3)(5/6) = 5/9
Thus, there are 5/9 of Ruby;s car.
Answer:
4.2 x 10⁶
Step-by-step explanation:
The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².
To do this, first you multiply the coefficients:
7 x 6 = 42
Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:
10² x 10³ = 10⁵
So the result would be:
42 x 10⁵
However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.
4.2 x 10⁶
