Answer:
The distance cover by Bell is 8 miles .
Step-by-step explanation:
Given as :
The distance cover by Mike = The distance cover by Pete = D miles
Let The distance cover by Bell = d miles
The distance cover by Mike = 15 miles + distance cover by Bell
i.e D = 15 + d ............1
Again
The distance cover by Pete = three time distance cover by Bell - 1 miles
i.e D = 3 × B - 1
Or, D = 3 d - 1 ............2
Now, Solving equation 1 and 2
So, 15 + d = 3 d - 1
Or, 3 d - d = 15 + 1
Or, 2 d = 16
∴ d =
i.e d = 8 miles
So,The distance cover by Bell = d = 8 miles
Hence, The distance cover by Bell is 8 miles . Answer
Answer:
59
Step-by-step explanation:
You will multiple them all 5*5=25,4*4=16,6*3=18 then add 25+16+18=59
Week 1=50
week 2= 50×2=100
week 3=100×2=200
week 4=200×2=400
week 5=400×2=800
week 6=800×2=1600
week 7=1600×2=3200
week 8=3200×2=6400
so the answer is 6400
Answer:
D) Of the 4 people who have a sister, 1 of them also has a brother.
Step-by-step explanation:
P(B/A) indicates the probability of event B when event A has alredy occured.
Event A = The person has a sister.
Event B = The person has a brother.
So now P(B/A) means the probability of the person having sister who already have brother.
Hence choice "D) Of the 4 people who have a sister, 1 of them also has a brother." is correct.
Is there 4 to the power of 8 because 4 times 4 eight times is 262,144
