What is 0.304 divided by 1.325 rounded to the nearest tenth?
Over [174]

We have to determine the number which is rounded to the nearest tenth in the expression 0.304\div 1.325.

So, let us divide 0.304 by 1.325.

So, we get 0.304 \div 1.325 = 0.229

Now, we have to round the number 0.229 to the nearest tenth.

The tenths place is to the right of the decimal. Now, we will consider the digit at hundredths place which is '2', which is less than 5.

Therefore, the number rounded to the nearest tenth is 0.2.

Answer:

5. A.

6. F

Step-by-step explanation:

5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3

y = 3x + b

using coordinates (-6,3)

3 = 3(-6) + b

b = 21

y = 3x + 21

6. I think F is the right answer
