Feet up a ratio for miles over time:

6/30 = x/45

Cross multiply:

30x = 270

Divide both sides by 30:

X = 270/30

X = 9 miles

using a protractor and a ruler draw a right triangle with a side length of 5cm that is beetween the right angle and a 30 degree
Elza [17]

The Triangle will look in this way (Attached image)-

<h3>How do you draw a 30 degree angle with a protractor?</h3>

Step 1: Draw a line segment OQ.

Step 2: Place the center tip of the protractor at point O such that the protractor perfectly aligns with line AQ.

Step 3: Start from 'Q' on the protractor in the anti - clockwise direction and stop at 30. Mark it as point 'P'. If point 'Q' lies to the right of 'O', then start measuring clockwise and stop at 30.

Step 4: Now, place the protector at point Q, mark the point 'P' at 90, such that ∠OQP = 90.

Step 5: Join point 'P' with 'O'. ∠QOP=30° is the required 30 degree angle.

The equation shows a number multipled by 8. n x 8 = Which is true about the product?
ikadub [295]

Answer:

  It is a multiple of 8

Step-by-step explanation:

The product may or may not be a factor of 8. We usually think of the factors of an integer as being positive integers, so the factors of 8 would be 1, 2, 4, or 8. If 8n is to be a factor of 8, then n must be 1/8, 1/4, 1/2, or 1. This will not be the case in general.

__

The product of 8 and any number is a multiple of 8. (Again, we usually think of a multiple of 8 as being an integer, which would require the number n to be an integer.)

__

No product of two (integer) numbers is a prime number. If 8n is to be a prime, then the value of n must be <em>(some prime number)/8</em>. Again, this will not be the case in general.

__

n is a factor of the product; not the other way around.
