(1) 34.8 liters
(2) $63.55
Solution:
(1) There is a mistake in question. It is 42 liters.
Total gasoline a car can hold = 42 liters
Liters of gasoline filled in beginning of the week = 35.8
Liters of gasoline used during the week = 28.6
Remaining liters of gasoline in the tank = 35.8 – 28.6
= 7.2 liters
Quantity of gasoline need to buy to fill the tank completely
= Total capacity – Remaining gas in the tank
= 42 liters – 7.2 liters
= 34.8 liters
Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.
Option B is the correct answer.
(2)
Shamika earns in first week = $25.75
Shamika earns in next week = $37.80
Total money Shamika have = First week earning + Second week earning
= $25.75 + $37.80
= $63.55
Don't add or subtract spending money, because the question is how much she have from these two weeks.
Hence Shamika have $63.55 from these two weeks.
Answer:
She can buy two pounds
Step-by-step explanation:
it is 10$ for one pound
you have 20$ so you just se how many times 10$ can
go into 20$ and that 2 so that's your answer. i hope it helped you? ;)
answer: n=7
work:
6n-14=3n+7
6n-14 (+14) = 3n+7 (+14) add 14 to both sides
6n=3n+21
6n(-3n)=3n(-3n)+21 subtract 3 from both sides
3n=21
3n/3= 21/3 divide by 3 on both sides
n=7
Answer: The required probability is 22.5%.
Step-by-step explanation:
Since we have given that
Probability of radio listeners live in Waterville = 0.75
Probability of radio listeners live in Newport = 0.25
Probability of radio station KTBC in Waterville = 0.20
Probability of radio station KTBC in Newport = 0.30
So, using "Multiplication rule of Probability":
Probability that the listener will be tuned in to station KTBC is given by
![0.75\times 0.20+0.25\times 0.30\\\\=0.15+0.075\\\\=0.225\\\\=22.5\%](https://tex.z-dn.net/?f=0.75%5Ctimes%200.20%2B0.25%5Ctimes%200.30%5C%5C%5C%5C%3D0.15%2B0.075%5C%5C%5C%5C%3D0.225%5C%5C%5C%5C%3D22.5%5C%25)
Hence, the required probability is 22.5%.
