1st problem:
A = 630 cm
2nd problem:
A = 104 cm
All I can see on the picture you provided.
The answer is x=-7 and x=-1
Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ = 
Cosθ = 
tanθ = 
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ = 
θ = 
Option (A) will be the answer.
Steps to Solve:
29.3 = 1.7y
29.3/1.7 = 1.7y/1.7
y = 17.2352941176
In this case, we round up the hundredths place because the number in the thousandths place is 5 or higher.
y = 17.24
Hope this helps!! :)

Answer:
12 1/2 laps
Step-by-step explanation:
To find the number of laps, divide the distance by the distance per lap.
(3 1/8) ÷ (1/4) = (3 1/8) × (4/1) = 3·4 +(1/8)·4 = 12 4/8 = 12 1/2
Quadir needs to jog 12 1/2 laps if he wants to jog 3 1/8 miles.
