Answer:

34.54 in (Answer C)

Step-by-step explanation:

The formula for the circumference of a circle whose radius is known is

C = 2πr.

Here, r = 5.5 and π ≈ 3.14, and so the circumference of the circle is

C = 2(3.14)(5.5 in) = 34.54 in (Answer C)

Triangle PQR has coordinates P(–8, 3), Q(–8, 6), and R(–3, 6). If the triangle is translated by using the rule (x, y) right-arro

omeli [17]

Answer:

Step-by-step explanation:

The rule (x, y ) → (x + 4, y - 6 )

means add 4 to the original x- coordinate and subtract 6 from the original y- coordinate, thus

P(- 8, 3 ) → P'(- 8 + 4, 3 - 6 ) → P'(- 4, - 3 )

Q(- 8, 6 ) → Q'(- 8 + 4, 6 - 6 ) → Q'(- 4, 0 )

R(- 3, 6 ) → R'(- 3 + 4, 6 - 6 ) → R'(1, 0 )

The sum of Ellie's age and Genya's age is 60. In six years, Genya will be eight times as old as Ellie. How old is Ellie now?

ArbitrLikvidat [17]

Answer:

<u>2 years old</u>

Step-by-step explanation:

Let Ellie's age ⇒⇒⇒ x

And Genya's age ⇒⇒⇒ y

∵ The sum of Ellie's age and Genya's age is 60

∴ x + y = 60 ⇒ (1)

∵ In six years, Genya will be eight times as old as Ellie

∴ (y + 6) = 8 (x+6)

∴ y + 6 = 8x + 48 subtract 6 from both sides

∴ y = 8x + 42 ⇒ (2)

By substituting from 2 at 1 with the value of y

∴ x + (8x + 42) = 60

∴ 9x = 60 - 42 = 18

∴ x = 18/9 = 2

∴ y = 60 - x = 58

So, Ellie's age now = 2 years old

And Genya's age = 58 years old
