Answer:
240
Step-by-step explanation:
Using the straight line formula; y=mx+c, take two points, for example, (4, 80) and (5, 100)
m=change in y/change in x, so;
m=(100-80)/(5-4)= 20
Take point (4, 80)
80=20×4 + c
80-80=c=0
so y=20x
y=20×12=240
Answer:
1400 square units
Step-by-step explanation:
The area can be computed by subtracting the areas of the white rectangles at three corners from the overall 60×30 rectangle.
The upper left corner white space is 10×10 = 100 square units.
The upper right and lower left white spaces are 15×10 = 150 square units each.
Then the shaded area is ...
60×30 -100 -2(150) = 1800 -100 -300 = 1400 . . . square units
_____
<em>Alternate solution</em>
You can extend each of the horizontal edges across the figure to divide it into three rectangles. From the top down, these have dimensions and areas of ...
35×10 +60×10 +45×10 = 10(35+60+45) = 10(140) = 1400 . . . square units
__
Area of a rectangle is the product of length and width.
Answer:
Step-by-step explanation:
Time taken for task 1:
Distance= 750m= 0.75 km
Speed= 10 km/hr
Time taken1= S (distance)/ V (speed)= 0.75/10= 0.075 hr= 4 mins and 30 sec
Time taken for task 2:
t2=S/V= 20/85= 0.24 hr= 14 mins and 24 sec
Time taken for task 3:
t3= S/V = 5/14= 0.36 hr= 21 mins and 36 sec
Total time took:
T1 +T2+T3= 40 mins and 30 second (approximately)
