The answer is -3 because you have to add 9 to both sides, then you have to divide by -7 to both sides to get your answer: f = -3
If you are not sure if the answer is right, then plug the answer in the problem to see your answer is correct or not.
$3.36 answer
Step-by-step explanation:
1 pound is 4 times 0.25 pounds.
$0.84 = 0.25 pounds
1 pound = $0.84 times 4
1 pound = $3.36
Technically, it would be $.34
Answer:
35°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle. The pole and its shadow form the legs of the right triangle with the side adjacent to the angle of elevation being the shadow. "TOA" tells you ...
Tan = Opposite/Adjacent
tan(elevation angle) = (pole height)/(shadow length)
tan(elevation angle) = 35/50 = 0.7
The inverse tangent function, arctan( ) or tan⁻¹( ), is used to find the angle from the value of its tangent.
elevation angle = arctan(0.7) ≈ 34.99° ≈ 35°
