Answer:
1. 8/$12=21/$x then cross multiply.
2. 1/$1.5, we're looking for cost so $1 is more reasonable
3. $31.5
Step-by-step explanation:
12x 21/ 8 = 31.5
Answer:
Step-by-step explanation:
Triangle DEF is a right angle triangle.
From the given right angle triangle,
DE represents the hypotenuse of the right angle triangle.
With ∠E as the reference angle,
EF represents the adjacent side of the right angle triangle.
DF represents the opposite side of the right angle triangle.
To determine EF, we would apply
trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 49 = EF/8
EF = 8Cos49 = 8 × 0.6561
EF = 5.2488
Rounding to the nearest tenth, it becomes 5.2
Step-by-step explanation:
Hey there!
f(x) = 7/x
<em>~ Simply keep the "7" in the place where "x" is there.</em>
![f(7) = \frac{7}{7}](https://tex.z-dn.net/?f=f%287%29%20%3D%20%20%5Cfrac%7B7%7D%7B7%7D%20)
Therefore, X= 1.
