Answer:

D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.

Step-by-step explanation:

Let us assume x = selling price of each soccer ball

y = daily profit earned from selling of soccer balls

Given that

Y= $-6x^2+100x-180$

where,

a = -6

b = 100

c = -180

Now we have to applied the formula which is as follows

x $= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$$

$= \frac{-100\pm\sqrt{100^2-4\times -6\times -180}}{2\times -6}$$

$= \frac{-100\pm\sqrt{10,000 - 4,320}}{-12}$$

$= \frac{-100\pm\sqrt{5.680}}{-12}$$

$= \frac{-100 + 75.3658}{-12}$$

$= \frac{24.6342}{-12}$

x^1 = -2.05285

Now

x^2 $= \frac{-100 - 75.3658}{-12}$$

$= \frac{- 175.3658}{-12}$

x^2 = 14.6138

Based on this the option D is most appropriate as per the given situation

What (3×5^2)/(5)^2 equal? Plz answer fast and with work and I will give brainliest

balu736 [363]

Answer:

The answer is 3.

Step-by-step explanation:

Given that the Indices Law is,

${a}^{m} \div {a}^{n} = {a}^{m - n}$

${a}^{0} = 1$

So the expression is :

$3 \times {5}^{2} \div {5}^{2}$

$= 3 \times {5}^{2 - 2}$

$= 3 \times {5}^{0}$

$= 3 \times 1$

$= 3$

A cube has an edge lengths of 5 cm. A rectangular prism has dimensions of 5 cm, 25 cm, and 1 cm. Which of the following statemen

murzikaleks [220]

The volume of cube and rectangular prism are same. Option B.

Step-by-step explanation:

Given,

The length of the edge of the cube (a) = 5 cm

The dimension of rectangular prism (l×b×h) = 5 cm×25 cm×1 cm

To find the relation between the volume of cube and rectangular prism.

Formula

The volume of a cube = a³ cube cm

The volume of rectangular prism = l×b×h cube cm

Now,

The volume of a cube = 5³ cube cm = 125 cube cm

The volume of rectangular prism = 5×25×1 cube cm = 125 cube cm

Hence,

The volume of cube and rectangular prism are same.
