5 x 1/4 = 1 1/4 or 1.25
4 x 1/2 = 2
1.25 + 2 = 3.25 or 3 and 1/4
17/2*11=187/2 in^2=A
4 margins at 1.3 in
187/2-4*13/10*17/2
187/2-884/20
1870/20-884/20
=49.3 in^2
Answer:
Area = 43.26
Step-by-step explanation:
There is a short way to do this.
Area = 1/2 s*t * Sin(R)
s = 14
t = 7
Area = 1/2 * 14 * 7 * Sin(62)
Area = 7 * 7 * sin(62)
Area = 49 * sin(62)
Area = 43.26
==================
There is another way you could do this.
Use the Cos law to find r
Then use Heron's formula to find the area. Trust me, you don't want to do that.
Doing the way I suggested gives 43.19. The difference is in what I did in the rounding. But I wouldn't want to type all the numbers.
Answer:
Step-by-step explanation:
Therefore, the volume of the water in the tank 25 minutes after Baxter begins filling the tank is 255 gallons.
Step-by-step explanation:
Linear Equation; Ax+By=C
A linear equation to model this situation:
8x + 55 = C
Where;
8 is for the rate of gallons.
'X' is the minutes.
55 is the gallons of water the tank already contained.
8(25) + 55 = 255
Where;
8 is for the rate of gallons.
25 is the minutes.
55 is the gallons of water the tank already contained.
In the equation of a straight line(when the equation is written as "y=mx+b), the slope is the "m" that is mutiplied on the x and the b is the y intercept where the line crosses the y axis
