Answer:
264ft^2
Step-by-step explanation:
First find the area of the body of the house which is the rectangle.
18*12=216
Then find the are of the triangle or roof given by 1/2(b)(h)
1/2(12)(10)=60
Then Find the area of the window which is 3*4=12 and subtract 12 from 60 to find the area of the roof with the window.=48
Add 48 the roof and 216 the rectangle to get total painted area. =264 ft^2
4 ft/sec
its the ratio of feet to seconds. determine by dividing the distance traveled (180ft) by the time it takes (45sec)
Ok, basically if you want to find when both equations are equal just make them equal to each other. 0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40.
From there use algebraic steps to find out what x is ( the break - even point ).
0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40
0.855625x - 4x + 20 = 1.265625x + 6x + 40
-0.41x - 4x + 20 = 6x + 40
-4.41x + 20 = 6x + 40
20 = 10.41x + 40
-20 = 10.41x
-1.92122958694 = x
Rounded to the nearest tenth it's -1.9 = x.

Answer:
13km
Step-by-step explanation:
Given data
Time= 8 days
Speed= 2 1/6 kilometers per day = 13/6 kilometers per day
Distance= ??
We know that
Speed= distance/time
therefore, Distance= speed*time
substitute
Distance= 13/6*8
Distance= 104/8
Distance= 13 km
Hence the crew did 13km
Figure 1 and figure 4 both have a area of 60.
