First you have to ask, how many minutes are in a day?
There are 60 minutes in a hour, and 24 hours a day. You would multiply these two to find how many minutes are in a day.
24×60=1440 minutes in a day.
Now to find how many passages a minute, divide the total number of passangers, by the number of minutes.
191,200÷1440=132.7778
Even though the 7 is bigger than a 5, you do not round up because it doesn't count as a full person.
132 people a minute is your answer.
Answer:
‐15−8= ‐15 + -8
‐15−(‐8)= ‐15 + 8
Step-by-step explanation:
‐15−8 = -23
‐15 + -8 = -23
‐15−(‐8) = -7
-15+8 = -7
First, begin by converting the tip of 12% to a decimal.
.12
Now, multiply that by the total bill.
.12*143=17.16
We now know the numerical value of the tip.
Add the tip to the total bill and get your answer.
143+17.16=160.16
Answer:
86
Step-by-step explanation:
Answer:
Ques 1: 7.85
Ques 2: both
and
are rational.
Ques 3: 0.9
Step-by-step explanation:
Ques 1:
Solving the
, we get 7.8485.
Rounding off to nearest hundredth, we see that next digit is 8, so we increase the previous digit by 1.
So, the answer to nearest hundredth is 7.85.
Ques 2:
and
to be checked whether they are rational or irrational.
We know that
is equal to 4.
= -4 which is a rational value.
Let us solve
now.
![\sqrt{0.25} = \sqrt{\dfrac{25}{100}}\\\Rightarrow \dfrac{5}{10}](https://tex.z-dn.net/?f=%5Csqrt%7B0.25%7D%20%3D%20%5Csqrt%7B%5Cdfrac%7B25%7D%7B100%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B5%7D%7B10%7D)
Which is a rational value.
So, both are rational.
Ques 3:
Simplify ![\sqrt{0.81}](https://tex.z-dn.net/?f=%5Csqrt%7B0.81%7D)
0.81 can be written as
in rational form.
Now, taking the square root, we need to take the square root for both Numerator and Denominator and then we can divide to get the desired square root.
![\sqrt{0.81} = \sqrt{\dfrac{81}{100}}\\\Rightarrow \dfrac{9}{10} = \bold{0.9}](https://tex.z-dn.net/?f=%5Csqrt%7B0.81%7D%20%3D%20%5Csqrt%7B%5Cdfrac%7B81%7D%7B100%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B9%7D%7B10%7D%20%3D%20%5Cbold%7B0.9%7D)
So, the answers are:
Ques 1: 7.85
Ques 2: both
and
are rational.
Ques 3: 0.9
