In order to fit 3 pictures across a page, the yearbook staff must reduce their portrait proofs using a scale factor of 8 to 5. Find the dimensions of the picture as they will appear in the yearbook.
a 7.8m object is represented in a picture as being 1.5cm. what is the scale factoré
2 1/2 by 3 1/8
To find the dimensions of the pictures, we need to use the scale factor of 8 to 5. The scale factor tells us how much smaller or larger the pictures in the yearbook will be compared to the original portrait proofs.
Let's assume the original dimensions of the portrait proof are length x and width y.
Now, we can use the scale factor to set up the following equation:
8/5 = x/newLength = y/newWidth
Divide both sides of the equation by 8 to isolate the new length and divide both sides by 5 to isolate the new width:
newLength = (8/5) * x
newWidth = (8/5) * y
Therefore, the dimensions of the pictures as they will appear in the yearbook are (8/5) times the original length and width.
