Answer:
72 dentists
Step-by-step explanation:
In this case, we can multiply 80 by 9/10 or .9 to get our answer.
If we were to multiply by 9/10 it would look like this:
But, if we were to multiply by .90 (remember that 9/10 = .9) it would look like this:
Therefore, if 9 out of 10 dentists recommended PurWhite toothpaste and 80 were surveyed then 72 out of the 80 would have recommended it.

Answer:
let the numbers be
X , y and z
X+ y + z = 20
first number is 4 times the sum of other 2
X = 4(y+ z)
second is 7 times third
y = 7z
now substituting back
X= 4 (7z + z)
X= 32z
32z + 7z + z = 20
40z = 20
z = 1/2
y = 1/2 * 7 = 7/2
X = 1/2 * 32 = 32/2
1/2 * 7/2 * 16 = 28
28 is the answer!
10x15= 150
150/2= 75
Diagonal = 75
Translations are all about shifting the same thing.
A is more of a rotation
C is more of an enlargement
D is a mere reflection of what's on the other side.
The pattern or image that could best be described by a translation is (B) seats on a school bus
