(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.
I got 4/27
I did 8/9 divided by 6/1
its b because you can round 363 to 400 and 553 to 600 400 + 600 = 1000
Answer:
Step-by-step explanation:
The distance is given by the expression![d=\sqrt{(\Delta x)^2+(\Delta y)^2}= \sqrt{[(-2)-(-7)]^2+[(-5)-(1)]^2} = \sqrt{(-2+7)^2+(-5-1)^2}=\sqrt{(5)^2+(-6)^2}=\sqrt{(25+36)}=\sqrt {61}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28%5CDelta%20x%29%5E2%2B%28%5CDelta%20y%29%5E2%7D%3D%20%5Csqrt%7B%5B%28-2%29-%28-7%29%5D%5E2%2B%5B%28-5%29-%281%29%5D%5E2%7D%20%3D%20%5Csqrt%7B%28-2%2B7%29%5E2%2B%28-5-1%29%5E2%7D%3D%5Csqrt%7B%285%29%5E2%2B%28-6%29%5E2%7D%3D%5Csqrt%7B%2825%2B36%29%7D%3D%5Csqrt%20%7B61%7D)
