Answer:
<h2>
6</h2>
Step-by-step explanation:
To find the width/length when you know the area and the length or width, you just divide the area by the known side.
45/7.5 = 6
Answer:
<em>9*364 - 9*125 - 9*39 = 1,800</em>
Step-by-step explanation:
<em>Mental Calculation</em>
If we detect known patterns in the calculations, we could easily give their results without the use of calculators.
We are given the expression to evaluate:
9*364 - 9*125 - 9*39
The first thing to note is the 9 is a common factor of all terms, thus we take it out:
9*(364 - 125 - 39)
The negative numbers can be easily added
125
+ 39
------------
164
Now our expression is much easier:
9*(364 - 164)
The subtraction of 364-164 is 200, thus the result of the operations is:
9*200. We only need to recall 9*2=18 and add two zeros to get 1,800, thus:
9*364 - 9*125 - 9*39 = 1,800

r = radius
h = height
Step-by-step explanation:
Answer:
Step-by-step explanation:
we are given
A student randomly guesses on 10 true/false questions
so,
there only true and false
so, probability getting true question is
so, probability getting false question is
the student gets 5 out of 10 questions right
so,
r=5
we can use binomial probability formula
now, we can plug values
we can simplify it
and we get
