.000007mm in scientific notation

7 x 10 ^ -6 power i believe is the right answer

Step-by-step explanation:

When putting a decimal such as 0.0000000009 in scientific notation the exponent will be negative. To figure out how to write scientific notation just find the number that you need to multiply by to get the number we have now. To get to 0.000007 we need to find 7 and multiply that by a negative exponent so that it turns into a decimal. We see that the decimal point from the number 7 moves over 6 times to the left to get 0.000007 meaning that our exponent is -6.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
