Answer:
5 Hours of work.
Step-by-step explanation:
Subtract 125 by 65 and we get 60. Then divide that 60 by how much he gets paid an hour ($12), and you get 5 hours of work until he can buy the bike.
Answer:
Hence, his driving cost of the trip= $ 145.
Step-by-step explanation:
It is given that:
Joshua is planning on 1404 miles driving trip.
His car gets an average of 36 miles per gallon.
i.e. for 36 miles his car uses 1 gallon of gas.
Hence for 1 mile his car uses=1/36 gallon of gas.
Hence, for 1404 miles his car uses=1404/36 gallon of gas
= 39 gallons.
Cos of 1 gallon of gas= $ 3.72
Cost of 39 gallons of gas=$ (3.72×39)=$ 145.08
which is approximately equal to $ 145.
Hence approximately his driving cost of the trip is $145.
Answer:
x=0
Step-by-step explanation:
factor out 4 from the expression
x - 4 = 1/4 * 4(2x - 4)
Reduce the numbers with the greatest common factor (4)
x - 4 = 2x - 4
cancel equal terms on both sides of the equation
x=2x
move the variable to the left-hand side and change its sign
x - 2x = 0
collect like terms
-x = 0
change the signs on both sides of the equation
x = 0
Hope this helps!!
The probability that the digits display a palindrome = 19/240 Ans.
As we know the total no. of possible hours = 12
Total number of possible minutes= 60
Therefore, total no. of possible times that can be shown are = 12
Since total no. of Palindromes possible per hour for the nine hours 1 through 9 = 6
No. of palindromes per hour from 10 through 12 = 1
Therefore, total no of palindromes = (6*9) + 3 = 57
Probability that the digits display a palindrome = 57/720 = 19/240
Answer:
Here we will use the relation:
Density = mass/volume.
We know that:
Mass = 1485g
Volume = 750L
Density = 1485g/750L = 1.98 g/L
We do not have the options in order to select the correct one, but knowing this density, we can suppose the possible gases.
Two "common" gases with densities similar to this one are:
Carbon Dioxide, with d = 1.977 g/L
Dinitrogen Monoxide, with d = 1.977 g/L
In both cases, if we round up we will get the same density that we calculated at the beginning, so either of these can be the correct option.
