Answer:

10 inches

Step-by-step explanation:

take the cube root of the volume to find the lenght of each side.

Answer:

10 inches

Step-by-step explanation:

The volume of a cube is of the form: [tex]V=s^3[/tex] , where s is the side length.

Here, we know the volume V, but not the side length. So, we can plug in the value 1000 in for V and solve for s:

1000 = [tex]s^3[/tex]

Cube root both sides:

s = [tex]\sqrt[3]{1000} =10[/tex]

Thus, each side is 10 inches.

The total length of the ribbon Samantha would need is given by the equation A = 7.2 feet

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total length of the ribbon be represented as A

Now , the equation will be

The number of pieces of ribbon required = 6 pieces

The length of each piece of ribbon = 1.2 feet

So , the total length of the ribbon A = number of pieces of ribbon required x length of each piece of ribbon

Substituting the values in the equation , we get

The total length of the ribbon A = 6 x 1.2

On simplifying the equation , we get

The total length of the ribbon A = 7.2 feet

Therefore , the value of A is 7.2 feet

Hence , the total length of the ribbon is 7.2 feet

Answer:

The answer is C :)

Step-by-step explanation:

Just took the quiz and got it right

The statement that shows a negative rate of change for the interval 0 to 2 on the x-axis is option C; On a coordinate plane, a parabola opens up. It goes through (negative 1, 4), has a vertex of (2.5, 0.25), and goes through (5.8, 4).

Suppose that we have to measure the rate of change of y as x changes, then we have:

[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.

(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)

The statement that shows a negative rate of change for the interval 0 to 2 on the x-axis is option C.

Answer:

∠ 3 = 25°

Step-by-step explanation:

The sum of the 3 angles 85, 2x and x - 10 are a straight angle = 180°

85 + 2x + x - 10 = 180, that is

3x + 75 = 180 ( subtract 75 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

Thus x - 10 = 35 - 10 = 25

∠ 3 and x - 10 are Alternate angles and congruent, thus

∠ 3 = 25°

Answer:

  112°

Step-by-step explanation:

The law of cosines can be used to find angle C from the three side lengths. The usual formulation of that law is ...

  c^2 = a^2 + b^2 -2ab·cos(C)

Then the angle C can be found to be ...

  C = arccos((a^2 +b^2 -c^2)/(2ab))

For the given side lengths,

  C = arccos((40^2 +56^2 -80^2)/(2·40·56)) = arccos(-1664/4480)

  C ≈ 112°

The question is about solving a system of equations representing the sales of adult and child tickets. You would use either substitution or elimination methods to find the individual prices of the adult (A) and child (C) tickets.

The subject of your query pertains to system of equations. In this problem, we can establish two equations based on the information provided: 4A + C = 55 and 3A + 2C = 50, where A represents the cost of an adult ticket and C is the cost of a child ticket. We can solve this using the substitution or elimination method. If we solve the first equation for A, we will obtain A = (55-C)/4. Substituting this into the second equation gives us 3((55-C)/4) + 2C = 50. Simplifying and solving this equation will provide us with the cost of the child ticket (C), which we can then substitute back into one of our original equations to find the price of an adult ticket (A).

Answer:

About 28.26 inches.

Step-by-step explanation:

The formula for circumfrence is c = 2(pi) * r.

We know that r = 4.5 (because the diameter is 9 inches).

So, the equation is c = 2(pi) * 4.5

Let's solve:

c = (2*3.14) * 4.5

c = 6.28 * 4.5

c = 28.26

Therefore, the final answer is 28.26 inches.

Of course, this is not exact because pi is irrational and goes on forever, but the question is asking for an estimate anyways.

Answer:

28.26

Just multiply 9x3.14 It would be different if it was the diameter and the diameter is 4.5

Answer:

The number of guppies were in the shop in the beginning = 60

Step-by-step explanation:

guppies ⇒ x , angelfish ⇒ y , goldfish ⇒ z

guppies to angelfish = 2 : 3 ⇒ x : y = 2 : 3 ⇒ x = 2/3 y

The number of angelfish was 2/3 the number of goldfish ⇒ y = 2/3 z

Or z = 3/2 y

The shopkeeper decided to replace 1/4 of the guppies with some angelfish. The number of angelfish she added was equal to the number of guppies she replaced

so, the number of guppies = 0.75x

and the number of angelfish = y + 0.25 x = y + 0.25 * 2/3 y

There were 30 more goldfish than angelfish in the end

z - (y + 0.25 * 2/3 y) = 30

so, 3/2 y - (y + 0.25 * 2/3 y) = 30

3/2 y - y - 1/6 y = 30

1/3 y = 30

y = 90

x = 2/3 y =2/3 * 90 = 60

z = 3/2 * 90 = 135

so, the number of guppies were in the shop in the beginning = 60

Final answer:

By setting up variables for the number of guppies (G) and angelfish (A) and establishing equations based on the given ratios, we can determine that the shop initially had 40 guppies.

Explanation:

To determine how many guppies were in the shop originally, let's set up variables for the number of guppies (G) and angelfish (A). According to the information provided, the ratio of guppies to angelfish is 2:3, which can be represented by the equation G/A = 2/3. The number of angelfish was also 2/3 the number of goldfish (F), meaning A = (2/3)F. When 1/4 of the guppies are replaced with angelfish, the number of guppies becomes 3/4G, and the number of angelfish becomes A + 1/4G. In the end, we are told there are 30 more goldfish than angelfish. Therefore, we have F = A + 30.

From A = (2/3)F and F = A + 30, we can substitute (2/3)F for A in the second equation, yielding F = (2/3)F + 30. Solving this equation for F gives us F = 90. Using the earlier equation A = (2/3)F, we find A = 60. Now, since A was 2/3 the number of goldfish originally, and using G/A = 2/3, we solve for G by setting up the equation G/60 = 2/3, leading to G = 40. Hence, there were 40 guppies in the shop initially.

Answer:

C: Jordana made a mistake when she calculated the length of side B.

Step-by-step explanation:

Jordana made a mistake while calculating the length of side B.

A scale factor is a factor by which dimensions of an object are enlarged or diminished.

One parallel length i.e. side A of original isosceles trapezoid = 12cm

One parallel length  i.e. side A of reduced isosceles trapezoid =4cm

So, scale factor = 4/12 =1/3

Other parallel length i.e. side B of original isosceles trapezoid =

So, the other parallel length i.e. side B of reduced isosceles trapezoid = 36*1/3 = 12cm

The side lengths of the reduced isosceles trapezoid = 30*1/3 = 10cm

So, the perimeter of the reduced isosceles trapezoid =4+12+10+10 =36cm

While Jordana calculated the length of side B as 4.

Thus, Jordana made a mistake while calculating the length of side B.
