Answer:

A

Step-by-step explanation:

The theorem we use for this is

a(a + b) = c(c + d)

Solve for d.

a(a + b) = c { }^{2}  + cd

a(a + b) -  {c}^{2}

\frac{a(a + b) -  {c}^{2} }{c}

A is the answer

Michael breeds chickens and ducks. Last month, he sold 505050 chickens and 303030 ducks for \$550$550dollar sign, 550. This mont
GenaCL600 [577]
Let the cost of a chicken be x and the cost of a duck, y, then

50x + 30y = 550 . . . (1)
44x + 36y = 532 . . . (2)

(1) x 6 ⇒ 300x + 180y = 3,300 . . . (3)
(2) x 5 ⇒ 220x + 180y = 2,660 . . . (4)

(3) - (4) ⇒ 80x = 640
⇒ x = 640 / 80 = 8

From (1): 50(8) + 30y = 550
⇒ 30y = 550 - 400 = 150
⇒ y = 150 / 30 = 5

Therefore, the price of a chicken is $8 and the price of a duck is $5.

The percentage of obese children aged 12-19 years in the United States is approximately P(t) = 0.04t + 4.6 if 0 ≤ t < 10 −0.0
Gwar [14]

Answer:

1975------ 4.8%

1990 ------ 11.48%

1985 ------ 8.51%

Step-by-step explanation:

Given

P(t) = 0.04t + 4.6 if 0 ≤ t < 10

P(t) = -0.01005t^2 + 0.945t - 3.4 if 10 ≤ t ≤ 30

Where

t:=0 implies year = 1970

Solving (a): Beginning of 1975.

First, we calculate the value of t

t = 1975 - 1970

t = 5

This falls in the range: 0 ≤ t < 10

So:

P(t) = 0.04t + 4.6

P(5) = 0.04 * 5 + 4.6

P(5) = 4.80

Solving (b): Beginning of 1990.

t = 1990 - 1970

t = 20

This falls in the range: 10 ≤ t ≤ 30

So:

P(t) = -0.01005t^2 + 0.945t - 3.4

P(20) = -0.01005*20^2 + 0.945*20 - 3.4

P(20) = 11.48

Solving (c): Beginning of 1985

t = 1985 - 1970

t = 15

This falls in the range: 10 ≤ t ≤ 30

So:

P(t) = -0.01005t^2 + 0.945t - 3.4

P(15) = -0.01005*15^2 + 0.945*15 - 3.4

P(15) = 8.51375

P(15) = 8.51
