Because vertical angles are congruent, angle 78 is congruent to angle x: x=78.
Answer:
The width of the art projects of area 63.6 square inches is 7.97 inches .
Step-by-step explanation:
Given as :
The area of the square art project = 63.6 square inches
Since The shape of the art project is square
So, The Area of square = A = side × side = side²
Now, let the measure of the width of art project = w inches
I.e side = w inches
or , A = side²
Or , A = w²
Or, 63.6 = w²
So, w = ![\sqrt{63.6}](https://tex.z-dn.net/?f=%5Csqrt%7B63.6%7D)
I.e w = 7.97 inches
So, the width of the projects = w = 7.97 inches
Hence The width of the art projects of area 63.6 square inches is 7.97 inches . Answer
Given:
Adam's locker has a password that consists of 4 non-repeated letters from A - Z.
To find:
The number of different passwords.
Solution:
Total number of letters from A - Z is 26.
So, the number of selecting a letter for first place is 26.
The passwords consists non-repeated letters. So, the remaining numbers is
.
The number of selecting a letter for second place is 25.
Similarly,
The number of selecting a letter for third place is 24.
The number of selecting a letter for fourth place is 23.
The total number of possible different passwords is:
![26\times 25\times 24\times 23=358800](https://tex.z-dn.net/?f=26%5Ctimes%2025%5Ctimes%2024%5Ctimes%2023%3D358800)
Therefore, the total number of different passwords is 358800.
Answer:
x^2 - x + 18
Step-by-step explanation:
f(x) = x^2+9
g(x) = x-9
Therefore f(x)-g(x),
= x^2 + 9 - (x - 9)
= x^2 + 9 - x +9
<h2>= x^2 - x + 18</h2><h2 /><h2 /><h2><u><em>
