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
C-7 hours, 0 minutes because between 8 and 11 are 3 hours and between 12 and 4 are 4 hours. 3+4= 7 hours
To answer this item, we are to multiply the given amount of wood that Jake can carry which is given to be 6 1/4 by the number of times his father can which is equal to 1 5/7. x = (6 1/4)(1 5/7)
x = 75/7
Thus, Jake's father can carry 10 5/7 pounds of wood. (I've had this question before btw)
Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
