Answer:
m = 6 , n = 6
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values
cos30° = , sin30° = , then
cos30° = = = ( cross- multiply )
2m = 12 ( divide both sides by 2 )
m = 6
and
sin30° = = = ( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
Answer:
98.4 mph
Step-by-step explanation:
Bobby has 10 miles to go, speed 82 mph, so the time is 10/82 hours.
Rick has 12 miles to go and has to do it in 10/82 hr
Speed is 12/(10/82)
i.e 12÷10/82 = 12× 82/10
=984/10 = 98.4 mph
The answer is $73
Explanation:
since you are buying five shirts for nine dollars each you would need to do 5x9 which equals 45. Now you need to do 12x2 since you bought two pairs of pants for twelve dollars each. 12x2 equals 24. Now you need to add 24 and 45 to see what your price is. 24+45=69. Now add on four dollars for shipping and handling and you will have $73 dollars. Hope this helps!
