Ryan and Carlos decided to sell their cups of hot chocolate for $2.75. They sold 12 cups. They spent $9.45 on supplies that they will need to pay back to the bank.



How much profit did Ryan and Carlos make?

Answer:

0.80

Step-by-step explanation:

The hundredth is 2 digits after the decimal.

Rounding 0.799, we want 0.xx

Look at the third digit, 9, meaning we round up.

However, since the second digit after the decimal is also a 9, we can make that a 0 by adding 1 to the first digit after the decimal.

We get 0.80

The transformed equation of  is  y = x³ is y =-1/7(x+8)³

Given that :

The equation of y=x^3 and Vertical compression by a factor of 1/7 ,horizontal shift 8 units to the left, reflection across the x axis

Applying the given transformations, we have:

To have a vertical compression by a factor of 1/7, we need to multiply the function by 1/7. So, we have:

y=1/7x³

We must add 8 to x in order to have a horizontal shift of 8 units to the left. We thus have:

y=1/7(x+8)³

A reflection over the x-axis would be the final step, we need to multiply the function by −1. So, we have:

y= -1/7(x+8)³

Therefore, the transformed equation is y= -1/7(x+8)³

Answer:

x = 4

y = 1

Step-by-step explanation:

x + 3y = 7 --> Eq1

4x - y = 15 --> Eq2

Find x in term of y using Eq1

x = 7 - 3y

Substitute x in Eq2

4(7-3y) -y = 15

28 - 12y - y = 15

-12y-y = 15 - 28

-13y = -13

y = -13/-13

y = 1

Find x

x = 7-3(1) = 4

If you have to solve for x first

Find y in term of x using Eq 2

y = 4x - 15

Substitute y in Eq 1

x + 3(4x -15) = 7

x + 12x - 45 = 7

x + 12x = 7 + 45

13x = 52

x = 52/13

x = 4

Find y

y = 4(4) -15 = 16 - 15 = 1

The area of the larger floor is 64 square units when w = 8 and l = 8. which is the correct answer would be an option (B).

To compare the values, we must first calculate each given situation. The area of any given rectangle is length times width.

If w = 7 and l = 9

A = l × w = 8 × 6 = 48

If w = 8 and l = 8

A = l × w = 8 × 8 = 64

So, the second case would obtain a larger area.

We prooved the paragraph proof of Theorem 3.8 that if two lines are perpendicular to the same line, then they are parallel to each other.

In the given question we have to explain the a paragraph proof of Theorem 3.8.

Let the lines that cross line a be m and n. Let m be parallel to a. As a result, the intersection of m and a produces four 90° angles.

Let n be parallel to a. This indicates that each of the four angles created by the intersection of n and an is 90 degrees.

The same-side internal angles (between lines m and n) are also congruent because all of the angles are congruent. The lines are parallel if two internal angles on the same side are congruent.

Write a paragraph proof of theorem 3-8: in a plane, if two lines are perpendicular to the same line, then they are parallel to each other.

Answer:

160 minutes can be spent on long distance calls each month.

Step-by-step explanation:

first we know that there is standard charge of $17 for basic service, $0.05 cost per minute with a budget of $25.

let's write that into an equation to solve for (a) which will be number of minutes.

17 + a(0.05) = 25

solving:

17 + a(0.05) = 25

carry across the 17 whilst changing the sign, or some people is also thought to minus on both sides to get rid of a certain variable.

a(0.05) = 25 - 17

a(0.05) = 8

carry across the multiplication of 0.05 which will then turn into division, or divide by 0.05 on both sides to remove it.

[tex]a = \frac{8}{0.05} [/tex]

a = 160

therefore 160 minutes can be spent on long distance calls each month.

You can redefine your answer more simply to hours by dividing by 60, which gives 2 hours and 40 minutes

The number of nickels and the number of dimes that Joseph has are 12 and 5 respectively.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

Let the no. of nickels be N and no. of dimes be D.

∴ N + D = 17...(i) and 0.05N + 0.1D = 1.45...(ii)

Multiplying (ii) by 100 we get 5N + 10D = 145...(iii)

Now multiply (i) by 5 we get 5N + 5D = 85...(iv)

The equation that models the function is P(t) = 20400(1,09)⁺ and the fox population in 2008 is 40648

From the question, we have the following parameters that can be used in our computation:

Initial population of fox = 20400

Rate of growth = 9 percent per year

These parameters can be presented as

Initial population of fox, a = 20400

Rate of growth, r = 9%

An exponential function is represented as

P(t) = a(1 + r)⁺

So, we have:

P(t) = 20400(1 + 9%)⁺

Evaluate

P(t) = 20400(1,09)⁺

Recall that

t = 0 in 2000

So, the value of t in 2008 is

t = 2008 - 2000

t = 8

Substitute t = 8 in P(t) = 20400(1,09)⁺

So, we have

P(8) = 20400(1.09)⁸

Evaluate

P(8) = 40648

Applying the definition of an Isosceles triangle, given that isosceles triangle TIC has a vertex angle I of 90 degrees, the measure of angle T is 45 degrees.

In geometry, an isosceles triangle is a triangle that has at least two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. Examples of isosceles triangles include the isosceles right triangle, the golden triangle, and the faces of bipyramids and certain Catalan solids.

The two equal sides are called the legs and the third side is called the base of the triangle. The other dimensions of the triangle, such as its height, area, and perimeter, can be calculated by simple formulas from the lengths of the legs and base. Every isosceles triangle has an axis of symmetry along the perpendicular bisector of its base. The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.

An Isosceles triangle has a vertex angle and two equal base angles.

Given that triangle TIC is an isosceles triangle:

angle I is the vertex angle = 90 degrees

angle T is a base angle

angle C is also a base angle

Thus:

angle C and angle T are congruent or equal to each other.

Therefore,

    Angle T = (180 - 90)/2

⇒ Angle T = 90/2

⇒ Angle T = 45 degrees.
