What we know:
12 hour period from 8pm to 8am
temperature dropped from 8°F to 16°F from 8pm to 8am
We need to find temperature at 4 am.
We can start by setting up points:
8pm is are starting point with 8°F, we can express it as (0,8), 0 represents initial time from 0 to 12 hour span.
8am is the ending point with 16°F, we can express it as (12,16), 12 represents the end time of 0 to 12 hours span.
We will use these points to find slope.
slope=m=(16-8)/(12-0)=8/12=2/3
Now, we can set up an expression to find any temperature at a specific time. Aslo, x represents the hours not the the specific time of 4am. We will use 8 since 4am is the 8th hour of the 12 hour span. Using slope of 2/3 and the y intercept of (0,8) since we were already at 8°F at the initial time of 0 we have the function:
f(x)=2/3x+8
f(8)=2/3(8)+8= 40/3≈13.3°

Answer:
14%
Step-by-step explanation:
The item dropped from $50 to $43 .
Therefore,
Decrease = $50 - $43
= $7
To get the % decrease, divide the decrease by the initial price and multiply the result by 100%
That’s
$7/$50 x 100%
$0.14 x 100%
= 14%
The price of the item decreased by 14%

Answer:
22.09
Step-by-step explanation:
0.5 of 44.18
of also means multiplication
so we're going to multiply 0.5 by 44.18
ie, 0.5×44.18=22.09
