Answer: x is 20
Because both angles together make up 180° you can simply rearrange the equation to get 8x+20=180 and by solving you can come to the conclusion x=20
Answer:
it will take her 2 hours and 45 minutes
Answer:
i believe it only has one solution, which would be x=12.
Step-by-step explanation:
Answer:
Step-by-step explanation:
The initial dimensions of the paper are:
(length)
(width)
After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.
For a triangle, the area is calculated as
where
b is the base
h is the height
Here we have:
Therefore, the area of the triangle is:
The answer is: [B]: " 3.99 * 10⁻⁶ " .

Note:

We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —

→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;

is the smallest value ; and as such, the correct answer.
