The smallest degree that you can rotate a pentagon is 36 degrees
Answer:
the value of both expressions when t = 3 is 33
the value of both expressions when t = 6 is 51
Step-by-step explanation:
33 33
51 51
Answer:
It costs $51
Expression:
16x = 68
12x = ?
Step-by-step explanation:
Lets first find out how much one sq. ft. of flooring costs:
16x = $68
x = $68/16 = $4.25
Next, lets multiply the unit rate by 12 to find the answer:
12x = Answer
12 * (4.25) = $51
Rational numbers are numbers that can be expressed as a fraction (ratio). Irrational numbers can not be expressed like that (like sqrt(2)).
To prove your statement, assume the opposite until you have a contradiction.
If the result of adding them would be rational, then your irrational number can be expressed as the difference of two rational numbers, which itself is also a rational number. That cannot be, because it should be an irrational number. This contradiction forces that rational + irrational = irrational.
You can reason the same way for multiplication. Suppose rational * irrational = rational, you find that your irrational can be expressed as the fration of two rationals, which is a contradiction.
Answer:
9(m+H) = a
Step-by-step explanation:
m=a/9-H
The first step is to add H to each side.
m+H = a/9 -H+H
m+H = a/9
Now multiply both side by 9
9(m+H) = a/9*9
9(m+H) = a
