Step-by-step explanation:
Number of combinations
= 5C2 * 7C3
= 10 * 35
= 350.
Hence there are 350 possible ways.
P.S.
5C2 = 5! / (2!3!) = 120 / (2 * 6) = 10.
7C3 = 7! / (3!4!) = 5040 / (6 * 24) = 35.
I believe it is C. Multiply 640 by 7.5. You should get 4800
Answer: b= - -log10(7)+3/2
Step-by-step explanation: log 10 (7) -2b-9=-6 : b= - -log10(7)+3/2 (Decimal : b = -1.07745...)
so these are the steps how I got it I did log 10 (7)-2b-9=-6 subtract log 10 (7) -9 from both sides log 10 (7)-2b-9-(log10(7)-9)=-6-(log 10 (7) -9)
Simplify -2b= -log10(7)+3
Divide both sides by -2 -2b/2= - log 10(7)/-2+ 3/-2 if you simplify it should give you b= - -log10(7)+3/2 that should be your answer but i'm not sure those I think that's how you do it let me know if you got it right bye!
√38 = 6.16 = 6.2
answer
last one 6.2
Answer:
