Express 0.006 in scientific notation

2 answers:

6 0

Hello!
To express the number 0.006 in scientific notation, or write the number in a different form where there are not as many zeroes, the first thing you need to do is move the decimal to the right until the number remaining is 1 or above and less than 10. When you do this, you should have moved the decimal right 3 times and resulted in 6. Then, multiply 6 by 10 to the power of the number of times you moved the decimal. This would result in your answer: 6*10^-3
**Note, when you move the decimal to the right, the power is negative and when you have to move it to the left, the power is positive

Have a great day!

6 x 10^-3 because the decimal point is 3 place value units away from the 6, and scientific notation is a x 10^n, where n can be a positive of a negative depending on the number

1600 children and 1400 adults attended

<h3>How to determine the number of adults?</h3>

Let the children be x and adult be y.

So, we have the following equations:

x + y = 3000

1.5x + 5y = 9400

Make x the subject in x + y = 3000

x = 3000 - y

Substitute x = 3000 - y in 1.5x + 5y = 9400

1.5(3000 - y) + 5y = 9400

Expand

4500 - 1.5y + 5y = 9400

Evaluate the like terms

3.5y = 4900

Divide both sides by 3.5

y = 1400

Substitute y = 1400 in x = 3000 - y

x = 3000 - 1400

Evaluate

x = 1600

Hence, 1600 children and 1400 adults attended

luda_lava [24]

Answer:

8 groups.

Step-by-step explanation:

We are told that Luis purchased 24 purple plants and 8 pink plants. He wants to plant them in equal groups in his garden. We are asked to find out largest number of groups he can make.

To solve this problem we will find GCF of 24 and 8.

Factors of 24 are: 1,2,3,4,6,8,12 and 24.

Factors of 8 are 1,2,4 and 8.

We can see that greatest common factor of 24 and 8 is 8.

Therefore, Luis can make 8 groups each having 3 purple plants and 1 pink plant.
