Weight of potatoes........Cost
12 lb ................................. $17
18 lb ................................. X
by cross multiplication we get
12 X = 17 × 18
12 X = 306
X = 306/12
X = $ 25.5
Answer:
37.8579
This value is approximate and rounded to four decimal places
===============================================
Explanation:
The tangent function is being applied to some unknown angle x. To isolate x, we undo whatever tangent is doing. So we apply the inverse function. Specifically the inverse tangent function. This is also known as "arctangent" and your calculator most likely shows it as a button with a "-1" exponent above the "tan"
So apply the arctangent to both sides to get
tan(x) = 0.7773
arctan(tan(x)) = arctan(0.7773)
x = 37.8579
Answer:
w = lap/ h - la
Step-by-step explanation:
1 Multiply both sides by a(w+p)a(w+p).
la(w+p)=wh
2 Expand.
law+lap=wh
3 Subtract law from both sides.
lap=wh-law
4 Factor out the common term w.
lap=w(h-la)
5 Divide both sides by h-la.
lap/h - la = w
6 Switch sides.
w = lap/ h - la
There are 7 fruit bars left from each box
845 ÷ 13 = 65
Hope this helps :)
