For this case we have that the variable "f" represents the number of cups of flour that Tomas had initially.

If of that amount Luis used [tex]3 \frac {1} {3}[/tex] of cups of flour, then we have the following expression:

[tex]f-3 \frac {1} {3}[/tex]

If Luis has[tex]1 \frac {2} {3}[/tex] cups of flour left, then we have the following equation:

[tex]f-3 \frac {1} {3} = 1 \frac {2} {3}[/tex]

Finally, the equation that represents the given situation is:

[tex]f-3 \frac {1} {3} = 1 \frac {2} {3}[/tex]

Answer:

  irrational

Step-by-step explanation:

Pi is irrational.

-1 is rational.

Their sum is irrational.

_____

In general, the sum of a rational number and an irrational number is irrational.

The number 'pi' is an irrational number. When we subtract 1 from 'pi', we still obtain an irrational number, therefore 'pi-1' is irrational.

The number pi is a well-known irrational number. An irrational number cannot be expressed as a ratio of two integers, and its decimal expansion never ends or repeats. When we subtract 1 from pi, we get another number. Since we are creating a new number by subtracting an integer from an irrational number, that number remains irrational. Therefore, pi-1 is also an irrational number.

Final answer:

The arc length intercepted by a central angle of π radians in a circle of radius 18.4 inches is calculated as arc length = θ × radius, resulting in 18.4π inches.

Explanation:

To find the arc length intercepted by a central angle of θ radians in a circle with radius r, we use the formula:

arc length (s) = θ × r

Given that the central angle θ is π radians and the radius r is 18.4 inches, we can compute the arc length as follows:

arc length (s) = π × 18.4 inches

By multiplying, we get:

arc length (s) = 18.4π inches

Therefore, the arc length intercepted by a central angle of π radians in a circle with a radius of 18.4 inches is 18.4π inches.

For this case we must find the value of the following expression:

We know that, Final Amount in Compound Interest is given by :

[tex]\bigstar\;\;\boxed{\mathsf{Amount = Principal\left(1 + \dfrac{Rate\;of\;interest}{100}\right)^{Number\;of\;Years}}}[/tex]

Given :

●  Principal = $5000

●  Rate of interest = 1.25

●  Number of Years = 10

Substituting the values in the Formula, We get :

[tex]\implies \mathsf{Amount = 5000\left(1 + \dfrac{1.25}{100}\right)^{10}}[/tex]

[tex]\implies \mathsf{Amount = 5000\left(1 + \dfrac{0.25}{20}\right)^{10}}[/tex]

[tex]\implies \mathsf{Amount = 5000\left(1 + \dfrac{0.05}{4}\right)^{10}}[/tex]

[tex]\implies \mathsf{Amount = 5000\left(\dfrac{4.05}{4}\right)^{10}}[/tex]

[tex]\implies \mathsf{Amount = 5000\times (1.0125)^{10}}[/tex]

[tex]{(2x - 3)}^{3} = {8x}^{3} - 36 {x}^{2} + 54x - 27[/tex]

EXPLANATION

Using the binomial theorem of Pascal's triangle, the coefficient of the third exponent binomial is :

1,3,3,1

The expansion for

[tex] {(a - b)}^{3} = {a}^{3} - 3 {a}^{2} b + 3a {b}^{2} - {b}^{3} [/tex]

To find the expansion for:

[tex] {(2x - 3)}^{3} [/tex]

We put a=2x and b=3

This implies that,

[tex]{(2x - 3)}^{3} = {(2x)}^{3} - 3 {(2x)}^{2} ( 3) + 3(2x) {(3)}^{2} - {3}^{3} [/tex]

This simplifies to:

[tex]{(2x - 3)}^{3} = {8x}^{3} - 36 {x}^{2} + 54x - 27[/tex]

Answer:

The maximum height of the marshmallow is 49 feet.

Step-by-step explanation:

The vertex form of a parabola is

[tex]y=a(x-h)^2+k[/tex]           .... (1)

Where, (h,k) is vertex of the parabola is a is constant.

The given function is

[tex]h=-16(t-14)^2+49[/tex]              ..... (2)

Where, h is height of the marshmallow (in feet) and t is the time (in seconds) after he throws the marshmallow.

From equation (1) and (2), we get

[tex]a=-16,h=14,k=49[/tex]

The value of a is -16, which is less than 0. So, the given function is a downward parabola.

The vertex of a downward parabola is the point of maxima.

The value of h is 14 and the value of k is 49. So, the vertex of the parabola is (14,49). It means the maximum height of the marshmallow is 49 feet in 14 seconds.

Therefore the maximum height of the marshmallow is 49 feet.

To find the cost of one bag of windflower bulbs and one package of crocus bulbs, we can use the substitution method. By setting up a system of equations and solving for the variables, we find that the cost of one bag of windflower bulbs is $45 and the cost of one package of crocus bulbs is $7.50.

To find the cost of one bag of windflower bulbs and one package of crocus bulbs, we can set up a system of equations. Let's use the substitution method.

Let x represent the cost of one bag of windflower bulbs and let y represent the cost of one package of crocus bulbs.

We can set up two equations:

2x + 5y = 105

9x + 5y = 164.50

From the first equation, we can rewrite it as: 2x = 105 - 5y. We can substitute this expression for 2x in the second equation:

9(105 - 5y) + 5y = 164.50

Solving for y, we get y = 7.50. Substituting this value back into the first equation, we can solve for x: 2x + 5(7.50) = 105. Solving for x, we get x = 45.

Therefore, the cost of one bag of windflower bulbs is $45 and the cost of one package of crocus bulbs is $7.50.

Follow below steps:

Mark and Julio are selling flower bulbs for a school fundraiser. To find the cost of one bag of windflower bulbs and one package of crocus bulbs, we set up two equations based on the information given, and then solve them using the substitution method.

Let x be the cost of one bag of windflower bulbs and y be the cost of one package of crocus bulbs. According to Mark's sales, the equation is:

2x + 5y = 105 ...(1)

According to Julio's sales, the equation is:

9x + 5y = 164.50 ...(2)

To use the substitution method, we first isolate y in equation (1):

y = (105 - 2x) / 5 ...(3)

Next, we substitute equation (3) into equation (2):

9x + 5((105 - 2x) / 5) = 164.50

9x + 105 - 2x = 164.50

7x = 59.50

x = 8.50

Now that we have the value for x, we can use it to find y by substituting x back into equation (3):

y = (105 - 2(8.50)) / 5

y = (105 - 17) / 5

y = 88 / 5

y = 17.60

Therefore, the cost of one bag of windflower bulbs is $8.50 and the cost of one package of crocus bulbs is $17.60.

Answer:

Sherina should have added 56 to both sides of the equation.

Step-by-step explanation:

To solve this equation: x-56=230 you need to add 56 to both sides of the equation:

x-56 + 56=230 + 56 → x = 286.

Therefore, Sherina should have added 56 to both sides of the equation.

Answer:

Last option: Sherina should have added 56 to both sides of the equation.

Step-by-step explanation:

To solve the equation [tex]x-56=230[/tex] Sherina needed to solve for the variable "x".

To calculate the value of the variable "x" it is important to remember the Addition property of equality. This states that:

[tex]If\ a=b\ then\ a+c=b+c[/tex]

Therefore, Sherina should have added 56 to both sides of the equation.

The correct procedure is:

[tex]x-56+(56)=230+(56)\\x=286[/tex]
