When a number with a power is given another power, the powers multiply. Thus,
(2^t)⁸
Answer: D. 78cm2
Step-by-step explanation:
SA=B+1/2ph
SA=28+1/2(20)(5)
SA=78cm2
The odds against the horse winning is given as 5:4
This means for every 5 times the horse loses it will win 4 times.
5 loses + 4 wins = 9 races.
The probability the horse wins would be 4 races out of 9 total races, which would be written as 4:9
Y = mx + b
m= 1/2 Then y = 1/2(x) + b
Calculate b
3 = 1/2.(4) + b
3 = 2+b and b = 1
Final equation y = 1/2(x) + 1
Answer:
It would be B (15x + 20x)
