Find the value of x, given that the two triangles are similar.​
8_murik_8 [283]

Answer:

10.5 is the correct answer.

Step-by-step explanation:

Due to the fact Triangle CAB has "6" as its length, and Triangle FDE has "2" as its length, you multiply 3.5 and 3.

3.5 x 3=10.5

2 x 3=6

3.5/2=10.5/6, so the answer is 10.5.

If you go with Blackburn, you have to pay 25 bucks right off, for the web services hosting setup, that's for them to add your account, and allocate resources on their end for you.

After that, for every passing month, you have to pay 5.69 bucks for the service they provide on daily basis.

if you with Randall, they also charge for setup fee, just cheaper, $6 at once, and then for every month is $9.49.

Blackburn for 

1 month     5.69(1) + 25

2 months   5.69(2) + 25

3 months  5.69(3) + 25

x months  5.69(x) + 25, or 5.69x + 25

Randall for 

1 month  9.49(1) + 6

2 months  9.49(2) + 6

3 months  9.49(3) + 6

x months  9.49(x) + 6, or 9.49x + 6

------------------------------------------------------------------------------------

y = 5.69x + 25
y = 9.49x + 6

Answer:

  • The center (2, 2.5), radius \sqrt{37} / 2

Step-by-step explanation:

<u>The standard form of the equation of a circle is: </u>

  • ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius

<u>Rewrite the given equation in the standard form:</u>

  • 2x^2 + 2y^2 - 8x + 10y + 2 = 0
  • x^2 - 4x + y^2 + 5y = -1
  • x^2 - 4x + 2^2 + y^2 + 5y + (5/2)^2 = -1 + 4 + 25/4
  • (x - 2)^2 + (y + 2.5)^2 = 37/4

<u>The center is:</u>

  • (2, 2.5)

<u>And radius is:</u>

  • <u />\sqrt{37} / 2

The price of a coat increased from $78 to $92. What is the price increase percentage?
svetlana [45]

Answer:

18%

Step-by-step explanation:

Percent change can be found using the following formula:

\frac{original-new}{original}*100

Original represents the initial cost where new represents the new cost.  We multiply the answer by 100 to get the percentage:

\frac{92-78}{78}*100 = 18%
