Answer:
slope is -1/2 and y- intercept is 1/3
Step-by-step explanation:
use y=mx+b
m=slope
b= y-intercept
rearrange your equation
y=1/3-1/2x
y=-1/2x+1/3
The diameter of the coaster is 5 cm.
Step-by-step explanation:
Given,
The area of the circle = 19.63 sq inch
To find the diameter, we need to find the radius
Formula
The area of a circle with radius(r) = π
sq cm
According to the problem,
π = 19.63
or, = 
= 6.2459
or, r = 
= 2.499 (approx)
= 2.5 cm
Hence the diameter of the circle = 2 × 2.5 cm = 5 cm
It is already given in the question that 2 iodine tablets are required to disinfect 1 quart of stream water. The thing that needs to be found is the number of tablets required to disinfect 4 quarts. As can be seen in the question, the information's provided are enough to get to the desired answer.
Then
Number of tablets required to disinfect 1 quart of stream water = 2
Number of tablets required to disinfect 4 quart of stream water = 2 * 4
= 8
So 8 iodine tablets are required to make 4 quart of stream water drinkable.
16 it's just double the the denominator and the top number
