Answer:
Option 3
Step-by-step explanation:
This may not be the most efficient way, but I solved each one and option 3 had the same answer as the question.
Here we have to convert 423 yards into feet.
first let us find the basic relation between yard and feet
1 yard =3 foot
so applying this to our question we get,
423 yard =423*3 foot = 1269 feet
Answer 423 yards =1269 feet
Percentage of pages of a book read by Katie = 32%
Total number of pages of the book read by Katie = 80
Let us assume the number of pages that the book has = x
Then
(32/100) * x = 80
32x = 80 * 100
32x = 8000
x = 8000/32
= 250
So the book has a total of 250 pages in it.
Then
The number of pages that Katie still needs to read = 250 - 80
= 170
So Katie needs to read 170 more pages in the book.
54 because the formula for the area of triangle is 1/2bh so you just substitute the b and h for 18 and 6
I can only help you if you give me a lot of points
