Answer: 20 miles
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
x^2 = a^2 + b^2
Where x is the hypotenuse of the triangle (in this case the distance between Dayton and Belleville) and a and b are the other sides.
Replacing with the values given:
x^2 = 16^2 + 12^2
x^2 = 256+144
x^2 = 400
x = √400
x = 20 miles

Answer:
The are 125:9
Step-by-step explanation:
When we know the scale factor
The lengths are related by the scale factor
The areas are related by the scale factor squared
The volumes are related by the scale factor cubed
Since the scale factor is 5:3
Cube each side
5^3: 3^3
125:9
The are 125:9
Answer:
29% . . . or . . . 290‰
Step-by-step explanation:
The ratio of weight of salt to weight of water was ...
(14.5 g)/(50 g) = 29/100 = 29%
Sometimes, salinity is expressed as "parts per thousand".
29/100 = 290/1000 = 290‰
_____
Use of the abbreviation "PPT" for "parts per thousand" is not recommended, as that abbreviation has several different interpretations, including "parts per trillion."
