Answer:
A is 10 dollar cheaper than B
Step-by-step explanation:
A : 40 dollars plus 45*2=90
90+40= 130 dollars
B:100 dollars 45*1=45
100+45= 145 dollars
Answer:
180, 180, 148, 180, 148
Step-by-step explanation:
The two rules in play here are ...
- the sum of interior angles of a triangle is 180°
- the angles of a linear pair are supplementary (they total 180°)
__
The first of these rules answers the first two questions:
- interior angles total 180°
- angles 1, 3, 4 total 180°
We can subtract the measure of angle 1 from both sides of the previous equation to find the sum of the remaining two angles.
- angles 3 and 4 total 148°
The second rule answers the next question:
- angles 1 and 2 total 180°
As before, subtracting the value of angle 1 from both sides of the equation gives ...
_____
<em>Additional comment</em>
Of course, the subtraction property of equality comes into play, also. For some unknown, X, you have (in both cases) ...
X + 32° = 180°
X +32° -32° = 180° -32° . . . . . . subtraction property of equality
X = 148° . . . . . . . . simplify
In the first case, X is the sum of angles 3 and 4. In the second case, X is angle 2 only.
You can see that there are 6 rock CDs, over a total of
So, the ratio of rock CDs over the total number of CDs is
Which is 15%.
So, yes, the answer is A
Answer:
x = 9.3
Step-by-step explanation:
tan 25° = x/20
0.4663 = x/20
x = 9.3
Answer:
Rises to the left and rises to the right.
Step-by-step explanation:
Since, the given function is f(x)=
, and the end behavior of the given function is determined as:
Consider the given function f(x)=, identify the degree of the function:
The degree of the function is : 4 which is even
And then identify the leading coefficient of the given function that is +2 which is positive in nature.
Hence, the function is positive and even in nature, therefore, the end behavior of the function will be rising to the left and rising to the right.
