Answer:
The stack is 4½ inches tall.
Step-by-step explanation:
If both books are the same thickness, you are adding 2¼ + 2¼. This means that it will be 4 and two quarters. 2/4 is the same as 1/2, so simplifying gives you 4½.
In 36 days will the science and math teachers both give tests on the same day again.
<u>Step-by-step explanation:</u>
Here we have , The 6th grade science teacher gives a test every 12 days and the math teacher gives a test every 9 days. Today, both the science and math are giving tests. We need to find In how many days will the science and math teachers both give tests on the same day again . Let's find out:
It's given that science teacher gives a test every 12 days and the math teacher gives a test every 9 days . In order to find the number of days after which they'll give test at same day , we will find LCM of 12 & 9 . i.e.
⇒
and ,
⇒ 
Hence , LCM of 12 and 9 is 36 . Therefore , In 36 days will the science and math teachers both give tests on the same day again.
Answer:
0.5000
Step-by-step explanation:
According To The Question,
The Area under the Standard Normal Curve, We Can Use the Statistical Tables , That Reported Area As P(z < a) .
Thus, We need to use the following Relationship.
Now solve, P(z > 0) = 1 - P(z < 0) ⇔ 1 - 0.5000 ⇔ 0.5000

Answer: I believe the answer is (2) 49
Explanation: The given ratio is 5:245
When simplified(245/5), it gives you 1:49!
There are no solutions to the equation.
Subtracting 3x from both sides gets you -12 = 1 which is never true therefore for any value of x you choose the equations will never equal each other
