Answer:
Step-by-step explanation:
=18÷[7+2{7+2(7-6)}+2]
=18÷[7+2{7+2×1}+2]
=18÷[7+2×9+2]
=18÷[7+18+2]
=18÷27
=
=9 two is 18 and 9 three is 27
So,
=
Answer:
D
Step-by-step explanation:
Because B can be simplified to 3-4 ( which is the ratio needed)
therefor we know that Dis the answer
Answer:
you will add $1.53 to every bracelet you make
Step-by-step explanation:
figure out what 85 percent of 1.80 is and then add that to 1.80 for the total price

1.80 + 1.53 = 3.33 (total cost)
Answer:
Option (1)
Step-by-step explanation:
Equation of the given wave function,
f(x) = acos(bx)
Here, a = amplitude of the wave
Period of the wave =
From the graph attached,
Amplitude =
=
= 4
Period of the wave = π - 0
= π
From the formula of the period,
Period =
b = 2
Therefore, a = 4 and b = 2.
Option (1) will be the answer.
