Answer:
c.
Step-by-step explanation:
You have to add all of your frequency’s together and divide by 6 for the 6 scores. your mean would be 2
3x - 7
The perimeter is the sum of all 3 sides of the triangle
To find the third side subtract the sum of the 2 known sides from the perimeter
x + 3 + 2x + 4 = 3x + 7
third side = 6x - (3x + 7 ) = 6x - 3x - 7 = 3x - 7
So 65 dollars was what she paid
each camera INCLUDED a 60% mark UP so
she sold each at a 60% markup
65 dollars=100% of origonal camers
she sold them for 100+60=160% of origonal price
65 dollars=100%
percent means parts out of 100 so
160%=160/100=1.6
find 160% of 65
'of' means multiply so
1.6 times 65=104
she sold each camera at $104
Descent = 10 feet
Time required = 2 1/2 minutes.
The rate of descent = (10 feet)/(2.5 mn) = 4 ft/min
In 6 minutes, the descent will be
(4 ft/min)*(6 min) = 24 ft
Answer:
(a) 4 feet/minute
(b) 24 feet
