Alvin decided to buy Samantha some candy. He bought her 6 lollipops and 5 petits 4 for $1.40 and then he decides to buy Megan 5 lollipops and 6 petits 4 for $1.35. How much did each cost

Answer: 1

Step-by-step explanation:

4^(-1) / 4^(-1)=

1/4 / 1/4=

1/4 * 4/1=      ==> Dividing by a number is basically multiplying its reciprocal

1*4/(4*1)=

4/4=1

According to the calculations made by Bob after downloading and calculating the correlation value as 0.5 from a given data set, he concludes that as the number of bedrooms in a particular home increase there is an increase in the selling price of the bed.

This increase in the selling price due to the increase in the number of bedrooms can be explained with the help of the Law of Demand which states that as the demand for a certain product increases its cost or the selling price also increases.

Thus, when Bob calculates the correlation factor, he finds that as the number of bedrooms increases there is also a hike in the selling price. As there should be a surplus to fulfill the demand for bedrooms.

According to the question, the standard equation for the circle is [tex]x^{2} +y^{2} =r^{2}[/tex] in which the points (x, y) are the circumference point and 'r' is the radius of the circle.

The given expression for the circle is shown below:

[tex]x^{2} +y^{2} -12x+6y-19=0[/tex]

Bring same variable terms to one side and again re-write the expression:

[tex]x^{2} -12x+y^{2} +6y-19=0[/tex]

Now, to do factors of the given expression add and subtract 36,9 on both the sides

[tex]x^{2} -12x+36+y^{2} +6y+9=19+36+9[/tex]

Answer:

∠ EBF = 16°

Step-by-step explanation:

note that EB is the angle bisector of ∠ ABF , then

∠ ABE = ∠ EBF = 2x and

∠ ABF = ∠ ABE + ∠ EBF , that is

7b - 24 = 2b + 2b

7b - 24 = 4b ( subtract 4b from both sides )

3b - 24 = 0 ( add 24 to both sides )

3b = 24 ( divide both sides by 3 )

b = 8

Then

∠ EBF = 2x = 2(8) = 16°

Answer: E: Infinitely many solutions

Step-by-step explanation:

Starting with 5x - 7x + 6, let's combine like terms.

5x - 7x is -2x.

Thus, we have -2x + 6 = -2(x-3)

Using the distributive property for the right side, we multiply -2 * x, and get -2x, and -2 * -3 and get +6.

Now we have -2x + 6 = -2x + 6. We have the same equation here, and know that there is infinitely many solutions here off the bat.

For sake of computations, let's solve and show our work.

Subtracting 6 from both sides, we have -2x = -2x.

Adding 2x to both sides, we get 0 = 0.

Thus, we have infinitely many solutions.

In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.

A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.

The sentence states an equality between a units of weight in grams (g) and kilograms (kg).

From there, we can say that we are asked how many kilograms are there in 180 grams.

Converting grams to kilograms, we must use the conversion

Adding integers with a common sign.

When adding two integers with a common sign, we just add the absolute value of the numbers and the resulting answer is marked with the same sign given in the question.

This question has two possible answers.

Possibility 1:

Both the integers are of positive sign. As a result, the resulting integer after addition is positive.

Example:

Let c = 45 and d = 53.

The sum of c and d is then

sum = c + d = 45 + 53 = 98

Possibility 2:

Both the integers are of negative sign. As a result, the resulting integer after addition is negative.

Example:

Assume c = -23 and d = -61.

The sum of c and d is then

sum = c + d = (-23) + (-61) = -(23 + 61) = -84

Using the Triangle Midsegment Theorem, the value of x in the figure is: 4.

The Triangle Midsegment Theorem states that:

The length of segment DE = 1/2(the length of segment BC)

Given the following;

DE = x + 1

BC = 4x - 6

Substitute

x + 1 = 1/2(4x - 6)

2(x + 1) = 4x - 6

2x + 2 = 4x - 6

2x + 2 - 4x = 4x - 6 - 4x

-2x + 2 = - 6

-2x + 2 - 2= - 6 - 2

-2x = -8

-2x/-2 = -8/-2

The measure of the angle 2 is 122°.

Given that angles 1 and 2 form a linear pair,

angle 1 + angle 2 = 180 degrees         —— (1)

We've also been notified that angle 2 is 6 times the size of angle 1.

That is to say: angle 2 = (2×angle 1) + 6      ———- (2)

Putting the angle 2 value in (1) from (2)

180 = angle 1 + 2×angle 1 + 6

3×angle 1 = 174

1st angle = 58 degrees  ———-(3)

(1) and (3) come from:

Area of rectangle is equal to the product of length and breadth.

Area =l×b

Here, the give area=1/6 miles² and b=1/4 mile.

Now, we will substitute the values in the formula, we get

1/6=l×(1/4)

Further, we will multiply both sides with 4, we get

4/6=4l/4

4/6=l

The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13). The measures of the angles RIG and ZIM are 59° and 140°, respectively.

In this problem we find a geometric system generated by lines GZ, AM and IR, in which two variables are shown (x, z) and whose values can be found by applying the concepts of complementary and supplementary angles.

A group of angles are complementary if the sum of their measures equals 90°, and supplementary if that sum equals 180°. This system can be represented by the following system of linear equations:

(3 · x - 56) + 90 + (4 · z + 7) = 180       (1)

(4 · z + 7) + (x + 2) = 90                        (2)

By (1):

(3 · x - 56) + (4 · z + 7) = 90

3 · x + 4 · z - 49 = 90

3 · x + 4 · z = 139                                  (1b)

By (2):

x + 4 · z = 81                                         (2b)

The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13).

Then, the measures of the angles RIG and ZIM are, respectively:

m ∠ RIG = 4 · z + 7

m ∠ RIG = 4 · 13 + 7

m ∠ RIG = 59°

m ∠ ZIM = 360° - (3 · x - 56) - 90° - (4 · z + 7) + (x + 2)

m ∠ ZIM = 360 - 3 · 29 - 56 - 90 - 4 · 13 + 7 + 29 + 2

m ∠ ZIM = 140°

The measures of the angles RIG and ZIM are 59° and 140°, respectively.
