I don't get any of the answers. If I go by order of operations I would multiply 1*9 first and get 9. Then 33+9+12=54
Sorry.
Answer:
8.29×10^-4
Step-by-step explanation:
hope it helps ,pls mark me as brainliest
5/25 = x/20
To solve a proportion cross multiply:
(5 * 20) = (25 * x)
Simplify:
100 = 25x
Divide both sides by 25:
x = 100/25
x = 4
In order to solve this problem, you must draw a right triangle first to help you visualize the path of the jogger.
You are given 0.5 miles north (which will be the height of the right triangle), and 1.3 miles (which will be the hypotenuse of the triangle).
Using Pythagorean Theorem: a²+b²=c², we have:
0.5² + b² = 1.3²
b = 1.3²-0.5²
b = 1.2 miles
Things to remember the sum of the measures of the interior and exterior angles at each vertex is 180 (supplementary angles)
add and equal to 180
3x-5+5x+17= 180
8x+12=180
8x= 168
x=21
substitute in the algebraic expression for exterior angle
3(21) -5=
63-5=58
58 degrees is the exterior angle
hope this helps
