Answer:
1
Step-by-step explanation:
Cosine = adjacent/hypotenuse
Cos A = 3/4.24
Cos B = 3/4.24
Since they are equivalent, Cos A/Cos B = 1
We take interest+interest+interest to equal interest
0.041=4.1%(25000) the amount invested+0.056=interest they want=0.048 the total amount wanting to earn 4.8% and x is the added money to invest.
0.041(25000)+0.056x=0.048(25000+x)
1025+0.056x=1200+0.048x
subtract the 0.048 from both sides
1025+0.008x=1200+x
Subtract the 1025 from both sides
1025-1025+0.008=1200-1025+x
0.008x=175+x
Now divide 175 by 0.008
x=21,875
Answer: c
Step-by-step explanation:
Answer:
b = 20 when a = 8.
Step-by-step explanation:
For this problem, we will simply plug the value of a=8 into the given equation for b, to find the value of b.
b = [ (a)^2 / 4 ] + 4
b = [ (8)^2 / 4 ] + 4
b = [ 64 / 4 ] + 4
b = [ 16 ] + 4
b = 20
Hence, when the value of a=8, then the value of b=20.
Cheers.
