Answer:
Step-by-step explanation:
first we simplify the ratio
5:8
8/5=1.6
1:1.6 so for every 1 dollar she save she spends 1.6
next we do 1040/1.6=650
1040-650=390
390:650
i hope this helps and is the correct answer pls let me know
Answer:
$ 2250
Step-by-step explanation:
3375 = s³
s = ∛3375
s = 15 ft.
floor area = s² = (15 * 15)
floor area = 225 ft²
the contractor charges $10 per ft².
therefore,
the hardwood cost = 225 x $10 = $2250
Answer:
Step-by-step explanation:
Angle 4 = angle 1 and angle 3 =angle 2 Corresponding angles for two parallel lines BD and AE
Triangle AED ||| BDE Angle angle congruent
... By compendo and dividendo
Thus proved
Since two lines are parallel we have corresponding angles equal and also
sides will be proportional in similar triangles
Using that and adjusting compendo and dividendo we get the desired result
Apply the radical rule to separate terms:
Cubicroot(-27) and cubic root(n^27)
Cubicroot(-27) = -3
Now you have -3 cubicroot(n^27)
Using the exponent rule
N^27 can be rewritten as (n^9)^3
Now you have -3 cubicroot((n^9)^3)
The cubic root and the 3rd power cancel out to get the final answer of
-3n^9
