Answer:
8 unit ^2 or 8cm^2
Step-by-step explanation:
area 1
1/2 ( 3 x 3 ) = 4.5 unit ^2
area 2 we split the triangle into half
= 1/2 ( 2 x 2) = 2 unit ^2
we know the other half is also 2 unit ^2 but we add then subtract
1/2 (1 x 1) = 0.5^2
To get
4.5 + 2+ 2 - ( 0.5) = 8 unit ^2
Answer:
85
Step-by-step explanation:
68 x 5 = 340
80 x 3 = 240
340+240=580
750-580= 170
170 ÷ 2 ====== 85
Answer:
b=-9
Step-by-step explanation:
b/-1=9
times both sides by -1
b=-9
Answer: 31.416
Step-by-step explanation: Multiply the diameter by pi OR you could divide the diameter by 2 and then use the formula 2(pi)(radius).
Probability = desired outcomes / total possible outcomes.
desired outcomes = rolling numbers less than 6
= {1,2,3,4,5}
= 5 desired outcomes
total possible outcomes= {1,2,3,4,5,6 }
= 6 possible outcomes
so 5/6
