The constant rate of proportionality is 12!
Answer:
23/56 centimeters
Step-by-step explanation:
all of the variables have a common denominator, so you can effectively ignore the denominator when solving.
1. you start off with 34/56 centimeter of chalk and Brian breaks off 23/56 centimeters worth, leaving you with 11/56 centimeters

Step-by-step explanation:
50 doubles to 100 for the 1st week. 100 becomes 200 the 2nd and 400 for the 3rd week.
<span>60cm^2 is the area of the triangle.
The formula for a triangle is A = 1/2bh. We know the base to be 12cm (you are allowed to rotate the triangle) and the height is 10cm. When we use that in the equation we get:
A = 1/2bh
A = 1/2(12)(10)
A = 60. </span>
The answer is 24/10 or 12/5
