Answer:
75
Step-by-step explanation:
3×(5) squared becomes 3× 25=75
Points: (0,4) and (2,-3)
Find slope: (-3-4)/(2) = -7/2
4 = -7/2(0) + b, b = 4
Equation: y = -7/2x + 4
Estimate = 0.3 × 400
estimate = 120
the dice will land on a five 120 times
Answer:
21.2 units ; 28 sq.units
Step-by-step explanation:
Let's start from the topmost point and go counter clockwise.
Slanted side =
= 2.8 units
Vertical side = 3 units
Horizontal side = 7 units
Vertical side = 3 units
Slanted side =
= 5.4 units
So, perimeter = 21.2 units
We can divide the figure into a rectangle(bottom) and triangle(top).
Total area = Rectangle + Triangle
= (3*7) + ( (1/2)*7*2 )
= 21 + 7 = 28
