Answer:
CD = 27
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sided are equal, that is
= , substitute values
= = 3 ( multiply both sides by 9 )
CD = 27
Given:
Basic cost = $45
Cost of long distance calls = $0.10 per minute
To find:
The total cost if you had 45 long distance minutes.
Solution:
Let the total cost be y for x minutes long distance calls.
Cost of long distance calls for one minute = $0.10
Cost of long distance calls for x minute = $0.10x
Total cost = Basic cost + Cost of long distance calls for x minute
Substitute x=45, to find the total cost if you had 45 long distance minutes.
Therefore, the total cost if you had 45 long distance minutes is $49.5.
Answer:
x = 5 or x = -11
Step-by-step explanation:
(x+3)²+8=72
x² + 6x + 9 + 8 = 72
x² + 6x -55 = 0
(x - 5) (x + 11) = 0
x = 5 or x = -11
Answer:
AX / AB = 6/18 = 1/3
AY / AC = 10/25 = 2/5
They are not similar because the two ratios is not the same.
Step-by-step explanation:
I'm not really sure okay!
Monthly amount, M = $102×4 = $408.
Also, yearly amount, Y = M×12 = $408×12 = $4896
It is given that 25% of the cost is contributed by Marcus.
Amount Marcus paid
Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.
Hence, this is the required solution.
