Simplify the following expression and write

Mathematics
1 answer:
lisov135 [29]3 years ago
6 0

Answer:

3.4*10^{1}

Step-by-step explanation:

When multiplying you use the number with least amount of significant figures in it since both 0.00045 and 0.0015 have two significant figures in them our final answer will have two significant figures in it. So the to solve and express in scientific notation we simply multiply:

(0.00045)(500,000)

0.0015 = .3375 but in scientific notation to two significant figures we write:

3.4*10^{1}

1. What is the slope of a line that is perpendicular to the x-axis ​
Ket [755]

Answer:

The slope of a line that is perpendicular to the x-axis ​is undefined.

Step-by-step explanation:

We know that the x-axis is a horizontal line.

  • We also know a line that is perpendicular to the x-axis ​is basically a vertical line.
  • As the slope of a perpendicular line is undefined because no matter what the value of y is, the x-value remains the same.

Therefore, the slope of a line that is perpendicular to the x-axis ​is undefined.

For example, the slope between (1, 2) and (1, 4) is:

Using the slope formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 = [4 - 2] / [1 - 1]

                  = 2 / 0

                  = ∞

Mrs. Davis bought 6 pounds of grades for $18. At this rate, how much would 72 ounces of grapes have cost?
saveliy_v [14]
This the problem we are looking at: 6 pounds/18 = 72 ounces /?
To solve this, we have to make the unit of measurement the same. There are 16 ounces in 1 pound. So, there are 72 ounces in 4.5. To find that you just do 72 divided by 16. This is the new problem we are looking at: 6 pounds/18 = 4.5 pounds/?
To find ?, you must divided 6 divided by 4.5 to find the difference between the two to keep the same rate. That equals 1.33333333. 
What is done to the numerator, you must do to the denominator to keep the same rate so now you divide 18 divided by 1.33333333 which equals 13.5

So for 72 ounces (4.5 pounds) it will cost $13.50

I hope this helps:)
