Answer:
180
Step-by-step explanation:
When you multiply the about lost per hour by the amount of time, you get the amount lost total.
6*8=48
then you add that to the amount in the pool now, and you have the original amount.
Answer:
2.25 miles
Step-by-step explanation:
When driving a car time taken is 20 minutes. This is equal to 20/60 hours , 1/3 hours / 0.3 hours
When riding a bike , time taken is 45 minutes. This is 45/60 hours , 3/5 hours/ 0.75 hours
The formula for speed is : Speed = Distance covered / time taken
The statement is that the driving speed is greater than biking speed by 4.5 mph
Assuming the distance to work is x miles then;
x/ 0.3 - x/0.75 = 4.5 ------eliminate 0.3 by multiplying each term by 0.3 to get
x- 0.3/0.75 x = 1.35 -------eliminate 0.75 by multiplying each term by 0.75 to get
0.75 x - 0.3 x = 1.0125
0.45 x = 1.0125
x= 1.0125 / 0.45
x = 2.25
Answer:
0.03125

Answer:
c
Step-by-step explanation:
The numbers are ordered, such that the first number (the largest one) is:
(5 + 1/2)
And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.
We want to see which of the following numbers is not on the list:
A) √25
B) 5.45
C) 5 12
D) 5.34
One of these numbers can only be in the list if it is larger than (5 + 1/3) and smaller than (5 + 1/2).
To see this easier, let´s rewrite both of these:
5 + 1/2 = 5 + 0.5 = 5.5
5 + 1/3 = 5 + 0.33 = 5.33
Then if a number is smaller than 5.33, the number can't be in the list.
Here we can see two numbers that are smaller than 5.33
These are:
Option A) √25 = 5 < 5.33
Option C) 5.12 < 5.33
And there is no number larger than 5.5
Concluding, the numbers that are not in Demichael's list are:
√25 and 5.12
