Answer:

$38.50

Step-by-step explanation:

⇒ Find 30% of 55:

30% of 55 = 16.5

⇒ But that’s not the answer. That’s 30% of 55. The question says it’s 30% <em><u>off</u></em>. So you need to subtract 16.5 from 55:

55 – 16.5 = 38.5

⇒ You can also see that you can just straight up do 70% of 55:

70% of 55 = 38.5

<u>Answer:</u> $38.50

<em>Hope this helps!</em> :)

What is the value of X

Answer:

Step-by-step explanation:

it's another one of those similar triangles

it's easier to see this one.

t /c = u / b

where

t = 7x + 3

c = 27

u = 35

b = 21

plug in the knowns

7x + 3 / 27 = 35 / 21

7x + 3  = 27 ( 35 / 21 )

7x + 3 = 9 ( 35 / 7 )     ( divided by 3 )

7x  + 3  = 9 ( 5)     ( 7 into 35 =5 )

7x  + 3  = 45

7x = 45 - 3

7x = 42  

x = 6

I checked it, the ratio is 1_2/3  :) for both, but you can check it too

How is this supposed to be solved, i don’t really understand.
dezoksy [38]

Answer:

$2561.99 a quarter

Step-by-step explanation:

Just add together what they pay every year, then multiply by 25.5% (because that's the quarterly premium.)

Annual cost = insurance + dental + vision

                    = 8900 + 772 + 375 = $10047 a year.

Quarterly cost = 25.5% of annual cost

   Whenever you see of, think of multiplication!

   25.5% = .255

Quarterly cost = .255 * 10047 = <u>$2561.99 a quarter</u>

HELP ME SOMEBODY PLSS
OverLord2011 [107]

Answer:

-6/8

Step-by-step explanation:

The rate of change is the same as the slope (I don't know if you have learned that term yet), but basically its the change in y's over the change in x's. to find this out, all you have to do is count from the point on the graph that is the farthest right (in this case, (6,1)), up to the y coordinate of the point farthest to the left (-2, 7) which is 6, and then count the number of spaces between the x coordinates, which is 8. put the rise (up and down count) over the run (horizontal count) in a fraction form, which gives you 6/8, and then notice how the line is pointing towards the bottom RIGHT hand corner making the line negative, so you need to make the rate of change negative, giving you the final answer of -6/8.
