Step-by-step explanation: For this question, we have to find out how much 15% off of 19.99 is by completing the following computations:
$19.99 x 0.15 = 2.9985
Now, let's deduct that amount off of $19.99 to get:
$19.99 - 2.9985 = $16.99
FINAL ANSWER: $16.99
Answer: -1
Step-by-step explanation: To evaluate this problem, the first thing we want to do is plug in the appropriate value for <em>x</em>.
When we do that, we get 
A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.
So up top if we follow our order of operations, the first thing we want to do is square the -2 before we subtract. So -2² is +4.
So in our numerator we have 4 - 8.
Down below, we have -2 + 6 which is +4.
4 - 8 is -4 and -2 + 6 is +4.
Answer:
35.8miles
Step-by-step explanation:
The scalene triangle is a type of triangle with sides of three different lengths and angles of three different measurements. In every scalene triangle, the shortest side is opposite the smallest angle and the longest side is opposite the largest angle
10 mph x 5hrs = 50 miles could be the longest side
+36 degree = 1/10 of full rotation, is likely to be opposite the smallest angle =20 degree opposite 20miles but we deduct 1/10 rotation to show 1/10 of 20 is 0.8 x 0.8 = 0.64 and is the inverse 1/10 of 36 degree.
We use trigonometry function the sine of the angle = the length of the opposite side. the length of the hypotenuse = 20/50 sin (30)= 1.25 and this estimates the larger angle 125
We find 35.8m through division.
We can check that 35.8 + 20 + 50 = 105.804 perimeter
We cna also multiply the radical adding -1 infront of the angle 36 and multiplifyling the scale of 5 and 2 = 2.5
2.17874 x -136 x 2.5 = -741
1800-741 = 1058/10 perimeter.
and each has angle 36, 124.8, 19.2
