I’ll do an example problem, and I challenge you to do this on your own!
If the example is find the difference between 0645 and 1200, we know that there are 60 minutes in an hour, so 0645 is 6 hours and 45 minutes or 6+45/60=6+3/4 of an hour by dividing both the numerator and denominator by 15. Finding that in minutes, we have 60*6+45=360+45=395 minutes due to that you add 60 minutes for every hour.
1200 is just noon, but that’s 12 hours, so we can convert that into minutes - 60*12=720
Finding the difference, we get
720
-395
_____ due to that -395=-400+5, so 720-400=320 and 320+5=325
325
Converting them back into hours, we get 325/60=5+25/60, which is 5 60 minute increments (5 hours) and 25 minutes, or 0525
Good luck, and feel free to ask any further questions!
Perimeter r / perimeter s = side r/ side s
Perimeter r = 72 cm
Perimeter s = 36 cm
Side r = ???
Side s = 6 cm
72/36 = side_r/ 6 Cross multiply
72 * 6 = 36 * side_r
432 = 36 side_r Divide by 36
432 / 36 = side_r
12 = side_r
First, change the fraction (decimal and percent) into gallon
Martha used 17% of the total oil, that means
Martha = 17% × 8 gallons
Martha = 0.17 × 8 gallons
Martha = 1.36 gallons
Brett used 0.18 of the total oil
Brett = 0.18 × 8 gallons
Brett = 1.44 gallons
Mike used 0.7 gallons
Second, compare the number of gallon they used
1.36
1 acts as ones
3 acts as tenths
6 acts as hundreths
1.44
1 acts as ones
4 acts as tenths
4 acts as hundreths
0.7 or 0.70
0 acts as ones
7 acts as tenths
0 acts as hundreths
Compare the ones, 1.44 and 1.36 both have 1 as the ones, however 0.7 has 0 as ones. Because 1 is greater than 0, 1.44 and 1.36 are greater than 0.7.
Now compare the tenth, 1.44 has 4 as the tenths, and 1.36 has 3 as the tenths. Because 4 is greater than 3, 1.44 is greater than 1.36.
1.44 > 1.36 > 0.7
Brett > Martha > Mike
Brett used the greatest amount of oil
Answer:
C. 4
Step-by-step explanation:
first off, we know we need the value of HJ to solve for GH. Luckily for us HJ is congruent to JK, and we have the values to solve for that using pythagorean theorum.
4^2 + JK^2 = 5^2
16 + JK^2 = 25
JK^2 = 9
JK = 3
now we can solve for GH
3^2 + GH^2 = 5^2
9 + GH^2 = 25
GH^2 = 16
GH = 4
Answer:
3,872.32
Step-by-step explanation:
the nearest hundredth is 2 numbers on the right of the decimal sign. So you round up from 5 to get answer above.
