10 cubic feets volume is equivalent to 25.85 inches.

Answer:

Option B

Step-by-step explanation:

Volume of a cube is:

[tex]A = s^3[/tex]

s - side length

All sides are the same length in a cube.

We are given the information that the total volume of the cube is 10 cubic feet.

[tex]10=s^3\\\\\sqrt[3]{10}=\sqrt[3]{s^3}\\\\\boxed{2.154435... = s}[/tex]

2.154435... ≈ 2.15

The approximate height of the cube is 2.15 inches.

Since the height of the shelf is 24 inches tall, the cube should be able to fit.

2.15 < 24

Option B should be the correct answer.

Hope this helps.

Alright,Alex let say we have factored a quadratic into two binomial, for example

[tex](5x + 3)(6x - 4)[/tex]

If we set both of those equal to zero

[tex](5x + 3)(6x + 4) = 0[/tex]

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

[tex]if \: ab = 0 \: then \: a = 0 \: and \: b = 0[/tex]

This means we set each binomal equal to zero to find it root.

[tex]5x + 3 = 0[/tex]

[tex]5x = - 3[/tex]

[tex]x = - \frac{3}{5} [/tex]

[tex]6x + 4 = 0[/tex]

[tex]6x = - 4[/tex]

[tex]x = - \frac{2}{3} [/tex]

So our roots are negative 3/5 and negative 2/3 using zero product property

Answer:

B

Step-by-step explanation:

By using graph of a function, the graph of the equation y + 6 = x + 4 has been shown below

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

here, we have,

At first, it is important to know about function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Graph of a function f(x) is the collection of points of the form (x, f(x))

The equation is y + 6 = x + 4

y = x + 4 - 6

y = x - 2

Answer:

27 years old

Step-by-step explanation:

What I know

Let D = Dave, S = Sabrina, etc. Then:

(1) [tex]D=0.15S[/tex]

(2) [tex]L=0.75S[/tex]

(3) [tex]R=3.00D[/tex]

(4) [tex]D+S+L+R=141[/tex]

Want to find R. Taking equation 3 and rewriting equation 4, we get

[tex]R=3.00D[/tex]

[tex]R=141-D-S-L[/tex]

So if [tex]R=R[/tex], then

[tex]3D=141-D-S-L-R[/tex]

[tex]4D=141-S-L[/tex] by adding [tex]D[/tex] to both sides.

Using equation 1 and equation 2, I can rewrite everything in terms of [tex]S[/tex] and get:

[tex]4(0.15S)=141-S-0.75S[/tex]

[tex]0.6S=141-1.75S[/tex]

[tex]2.35S=141[/tex] by adding [tex]1.75S[/tex] to both sides.

[tex]S=60[/tex] by dividing 2.35 both sides.

Now that I know Sabrina's age, I'll work towards getting Rhianna's using equation 1 and equation 3:

[tex]D=0.15(60)=9[/tex]

[tex]R=3.00(9)=27[/tex]

Checking my work:

Dave: 9

Sabrina: 60

Luca: 45 (since 9+60+45+27=141)

Rhianna: 27

9 is 15% of 60

45 is 75% of 60

27 is 300% of 9

Answer:

The side length can be used to draw (0) unique triangles because the two side lengths (8 and 12) add together to a sum that is (less than) the third side length

Step-by-step explanation:

Answer:

$20.40 after the discount

Step-by-step explanation:

To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6

Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40

Answer: 7.5 miles per hour

Step-by-step explanation:

First speed was 3 miles per hour.

Second speed was 12 miles per hour.

To do an average, add both speeds and divide by two, which is the number of trips made.

= (3 + 12) / 2

= 15 / 2

= 7.5 miles per hour

9n means 9 times 6. Which equals to 54, subtract 4 to get 50

Answer:

50

Step-by-step explanation:

If n = 6 the equation becomes 9(6)-4 or 9 x 6 - 4

9 x 6 = 54

54 - 4 = 50

Thus, the answer is 50

  (x, y) ⇒ (x -5, y +3)

Step-by-step explanation:

Pick a point on the original polygon. The extreme left point (at (1, 0)) will do.

Locate the corresponding image point on ABCDE. (It is point B(-4, 3).) Using coordinates, or counting grid squares, determine what must be added to the original point to get the image point.

Here, that addition is 5 squares left and 3 squares up:

  image - original = (-4, 3) -(1, 0) = (-5, 0)

So, the transformation rule adds -5 to each x-coordinate and 3 to each y-coordinate:

   (x, y) ⇒ (x -5, y +3)

Answer:

Step-by-step explanation:

Answer:

Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.

Step-by-step explanation:

The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850

where,

x = number of cell phones sold.

Profit = Revenue - cost

= (2x² + 55x + 10) - (2x² – 15x – 40)

= 2x² + 55x + 10 - 2x² + 15x + 40

Profit = 70x + 50

Profit = 70x + 50

= 70(240) + 50

= 16,800 + 50

= $16,850
