Answer:
CA = 22.6 ft
Step-by-step explanation:
For the known angle A, leg CA is the adjacent leg.
Side AB is the hypotenuse.
The trigonometric ratio that relates the adjacent leg tot eh hypotenuse is the cosine.
cos A = adj/hyp
cos 41° = CA/(30 ft)
CA = 30 ft * cos 41°
CA = 22.6 ft
Answer:
3,5
Step-by-step explanation:
She walked 11.25 miles because she walked 3.5 mi. the first day, 3.75 mi. the second day, and 4 mi. the third day.
M: cost per hour
b: initial charge fee
x: hours (h)
To make both company to charge the same amount:
12x+376=15x+280
376-280=15x-12x
96=3x
X=32
So it took 32 hour to 2 company charge the same amount.
The cost gonna be: 12.(32)+376=760$
