I would get $19 back if I gave the clerk $40

An equation is an expression used to show the relationship between two or more variables and numbers.

Total money spent on book and CD = $12 + $9 = $21

The money gotten back = $40 - $21 = $19

I would get $19 back if I gave the clerk $40

If a → b is true, then ~a → b is also true.
Rasek [7]

Answer:

False

Step-by-step explanation:

To determine whether the statemaent "If a\Rightarrow b is true, then \neg a\Rightarrow b is also true" holds, you can form the truth table:

\begin{array}{ccccc}a&b&a\Rightarrow b&\neg a&\neg a\Rightarrow b\\1&1&1&0&1\\1&0&0&0&1\\0&1&1&1&1\\0&0&1&1&0\end{array}

When the result of the column a\Rightarrow b takes value 1 (true), the result of the column  \neg a\Rightarrow b is not always 1, then the statement is false.

What is the measure of angle 1?
frutty [35]
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°

Sum of all the adjacent  angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°

If the area of the rectangle is 90 km?, then what is the value of the missing side?
r-ruslan [8.4K]
I believe it would be B.
Logically, it’s the only one that makes sense,
As 9x10= 90
None of the others have any way to divide or multiply up to the area,
So yes, B.

I don’t know how to solve this it’s exponents.
matrenka [14]

Answer:

9^6

Step-by-step explanation:

When dividing exponents with the same base, we subtract the exponents

a^b/ a^c = a^(b-c)

9^11/9^5 = 9^(11-5)

              = 9^6
