statuscvo [17]

Answer: 170.37 acres

Step-by-step explanation:

In 2005, x= 2005

Substituting x=2005 in the equation.

A(2005) = (2078x-94458)/(13x-2164)

A(2005) = 4071932/23901

Please help me Arithmetic Reasoning
jek_recluse [69]

Step-by-step explanation:

Price of Jeans = $78.35

30% coupon = 30% × $78.35 = $23.51

6% sales tax = 6% × $78.35 = $4.70

1% local option tax = 1% × $78.35 = $0.78

Total cost of jeans = $78.35 - $23.51 + $4.70 + $0.78 = $60.32

Raul has 56 bouncy balls. He puts three times as many balls into red bags as he puts into green gift bags. If he puts the same n
Sati [7]
If we divide 56 by 4 we get 14.  Why by4?  So that one number is 3 times the other So he had 14 balls that went into the green bags and 42 (56-14) that went into the red bags.  We could just answer the question and say 14 but I think they want to know how many in each green bag.
14 and 42 don't work because they are not the same number of balls.  What number is a common factor?  7 is,
We could have 2 green bags and split the 14 balls into 2 groups of 7 and with the remaining 42 - put them into 6 red bags of 7 each.
And so the answer to your question is:
7 ball in each bag  = 2 bags are green, and 6 bags are red
                                        14 balls              +    42 balls            = 56 bouncy balls

Suppose that an individual has a body fat percentage of 15.9% and weighs 159. How many pounds of her weight is made up of fat? R
Anna007 [38]

Answer:

25.3 lb

Step-by-step explanation:

We can multiply the whole by the percentage to find the part. Since 15.9% is equal to 0.159, the weight of fat is 159*0.159 = 25.281. Round this to the nearest tenth, and we get 25.3 pounds.

A circle with the equation (x + 6)2 + (y + 3)2 = 16 is reflected over the line x = 2.
fomenos

Answer: (x-10)^{2}+(y+3)^{2}=16

Step-by-step explanation:

We know the center of the original circle is (-6, -3). After reflecting this over the line x=2, the new center is now (10, -3).

Thus, the equation of the circle is (x-10)^{2}+(y+3)^{2}=16.
