4. Is positive 63
I think so
Answer: 170
Step-by-step explanation:
The formula for the area of a triangle is 1/2bh, where b is the base length, and h is the height.
So- Essentially you’d just need to plug in the variables to solve this. the semicircle on the bottom serves to tell you the base length.
1/2(20)(17)
170
Answer:
Train A = 214
Train B = 86
Step-by-step explanation:
a + b = 300
a - b = 128
a + b = 300
a = 128 + b
(128 + b) + b = 300
128 + b + b = 300
128 + 2b = 300
2b = 300 - 128
2b = 172
b = 172 ÷ 2
b = 86
a = 128 + b
a = 128 + (86)
a = 214
Since you are giving no information whatsoever, the formula could be:
S = (1/2)g.t², where s is the distance, 9 =9.8 m/s² and t = time
S = (1/2).(9.8)(2.2)² ans S= 23.7 meters
