You place three orders for 100 soccer balls which cost $22 per ball. You receive all 300 balls. There is a delivery charge of $2

julsineya [31]

Answer:

Average cost per ball: $22.2

Step-by-step explanation:

Cost per ball: $22

Cost of 300 balls: 300 × 22 = $6600

Total No. of Orders: 3

Delivery fee per order: $20

Total Delievery fee: 20 × 3 =$60

Total cost including delivery cost: $6600 + $60 = $6660

$Average cost per ball = \frac{Total cost}{No. of balls}$

$Average cost per ball = \frac{6660}{300}$

$Average cost per ball = $22.2$

observe as seguintes situações e sua representação em linguagem matematica dois numeros x e y são tais 2x y=6 x-y=3

agasfer [191]

Answer:

The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"

Step-by-step explanation:

Given values:

$2xy =6.....(a)\\\\x-y= 3.....(b)\\\\$

After solve equation (a) we get

$\ equation: \\\\2xy= 6\\\\xy =\frac{6}{2} \\\\xy = 3.....(x)\\\\$

After solve equation (b) we get

$\ equation: \\\\x-y =3\\\\x= 3+y....(x1)\\$

put the value of x in to equation (x)

$(3+y)y = 3\\$

$y^2+3y-3=0\\\\\ compare \ the \ value \ with \ ay^2+by+c=0\\a= 1\\b=3\\c=-3\\\ Formula: \\y= \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\y= \frac{-3\pm \sqrt{9+12}}{2}\\y= \frac{-3\pm \sqrt{21}}{2}\\$

The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29

Answer:

$125.97

Step-by-step explanation:

To answer this question, simply plug the known values into the equation. We know that 100 is the principal (starting amount), 0.08 is the interest rate as a decimal, and t is 3 years.

Now plug in all those values to the given formula: B = p(1 + r)^t

Solve, and you end up with $125.9712, rounded to $125.97
