A) 2,4
B)3,2
C) 4,-3
I hope this helps
The ratio of the area of the sector (S) to the area of the entire circle (C) is equal to the ratio of the angle subtended to form the sector (As) to the angle for the whole revolution (Ac)
S / C = As / Ac
Substituting the given,
S / 36 m² = 40 degrees / 360 degrees
Solving for S gives, S = 4. Thus, the area of the sector is 4 m².
Use the Pythagorean Theorem (which is only true for right triangles)
a^2 + b^2 = c^2
where
a = 25
b = 312
and c = 313
25^2 + 312^2 = 313^2
625 + 973244 = 97969
97969 = 97969
this is a true statement
therefore your ramp Is indeed a Right Triangle
Answer:
per one foot of aluminum foil it costs .62 cents
Step-by-step explanation:
there are 3 ft in a yard
so 3 x 3 is 9 which is the total amount of feat
then divide 5.58 by 9
5.58 /9 = .62
this means that per one foot of aluminum foil it costs .62 cents
Answer:
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
balanced equation : 4 Al +3O2 → 2 ALO3
Step-by-step explanation:
Al + O2 → Al2O3
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6
the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.
