(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.
If you start at (-3,1) and end up at (0,3), you will have increased x by 3 and y by 2. Thus, the slope of this line is m = rise / run = 3 / 2.
Using the point-slope form of the equation of a straight line, we get:
y - 1 = (3/2)(x+3).
This could be rewritten in other forms:
y = 1 + (3/2)x + 9/2, or y = 2/2 + (3/2)x + 9/2, or y = (3/2)x + 11/2.
Given:
average of five numbers is 16 and four of the number are 12 , 14, 16 and 18
To find:
the remaining number
Solution:
The given numbers are 12,14,16,18
Let the another number be X
Sum of five numbers = 12+14+16+18+X
=60+X
Average of five numbers =16
Average= Sum of observations/no.of
observations
=>16=(60+X)/5
=>(60+X)/5=16
=>60+X=5×16
=>60+X=80
=>X=80-60
=>X=20
Answer:
The fifth number is 20
