Answer:a
Step-by-step explanation:
throughout the table it is presented that the answer, A, is correct becuase within the percentages is is obvious that a is correct.
T=(60cos78, 60sin78)
T=(12.47, 58.69)
C=45
d=√((45-12.47)^2+58.69^2)
d≈67.1km
Answer: $9
Step-by-step explanation:
Let the cost for adults be a
Let the cost for students be b.
The first van transported 2 adults and 5 students and cost $77. This will be:
2a + 5b = $77
The second van transported 2 adults and 7 students and cost $95. This will be:
2a + 7b = $95
2a + 5b = 77 ...... equation i
2a + 7b = 95 ........ equation ii
Subtract equation ii from I
-2b = -18
b = 18/2
b = $9
An student cost $9
Put the value of b into equation i
2a + 5b = 77
2a + 5(9) = 77
2a + 45 = 77
2a = 77 - 45
2a = 32
a = 32/2
a = 16
An adult costs $16
Answer:
18x +9h
Step-by-step explanation:
Such problems are tedious, but not difficult. The trick is to avoid making mistakes in the algebra.
5/8 = 0.625 = 62.5%
If 62.5% were glazed then you must find 62.5% of 24.
Equation…
x=0.625(24) = 15
if each costs $0.84 cents plus tax then you will multiply by 15.
15 x .84 = 12.6
The total cost was $12.60
