Step-by-step explanation:

We need to divide to know how much Mrs. Fletcher received for the coins

[tex]\frac{\$300}{5}=\$60[/tex]

She received $60 for each coin.

Now, each coin had a cost of

[tex]\frac{\$32}{5}= \$6.40[/tex]

So, he earned a profit of

[tex]\$60 - \$6.40=\$53.60[/tex]

Answer:

Option C is the answer.

Step-by-step explanation:

A florist sale is for it's first month is represented by the equation y = 168x + 8

Here y represents the sales in dollars and x represents number of days.

Now we have to calculate the number of days it took to reach $3200 in sales.

For this we will substitute $3200 in place of y and find the value of x by solving the equation.

3200 = 168x + 8

168x = 3200 - 8 = 3192

[tex]x=\frac{3192}{168}=19[/tex]

Therefore Option C. is the correct option.

If ABCDE is a regular pentagon and diagonals EB and AC intersect at O, then the degree measure of angle EOC is 108°.

In Mathematics and Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:

Sum of interior angles = 180 × (n - 2)

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

Sum of interior angles = 180 × (5 - 2)

Sum of interior angles = 180 × 3

Sum of interior angles = 540°.

Therefore, the measure of each interior angle is given by;

Interior angle of a pentagon = 540°/5

Interior angle of a pentagon = 108°

From triangle EAO, we have:

2m∠EOA = 180° - (54 + 54)°

m∠EOA = 72°/2

m∠EOA = 34°

Now, we can determine the measure of angle EOC;

m∠EOC = 180° - (34 + 34)°

m∠EOC = 108°

The value of A+B is [tex]\left(\begin{array}{ccc}3&-3\\10&4.5\\10&-1\end{array}\right)[/tex] and the value of 3A is  [tex]\left(\begin{array}{ccc}6&-9\\0&15\\21&-6\end{array}\right)[/tex] .

To add two matrices, we have to add the element present in the same position in the respective matrices.

(A+B)ij= Aij + Bij

where i is the no. of row and j is the no. of column.

In order to multiply a scalar by the matrix, we have to multiply that scalar with every element of the matrix.

nA= nAij

Here given matrix is

A= [tex]\left(\begin{array}{ccc}2&-3\\0&5\\7&-2\end{array}\right)[/tex]

and the other matrix is

B= [tex]\left(\begin{array}{ccc}1&0\\10&-1/2\\3&1\end{array}\right)[/tex]

The sum of the matrix is A+B=  [tex]\left(\begin{array}{ccc}2&-3\\0&5\\7&-2\end{array}\right)[/tex]+  [tex]\left(\begin{array}{ccc}1&0\\10&-1/2\\3&1\end{array}\right)[/tex]

⇒ A+B =[tex]\left(\begin{array}{ccc}2+1&-3+0\\0+10&5+(-1/2)\\7+3&-2+1\end{array}\right)[/tex]

⇒ A+B= [tex]\left(\begin{array}{ccc}3&-3\\10&4.5\\10&-1\end{array}\right)[/tex]

the value of 3A= 3 [tex]\left(\begin{array}{ccc}2&-3\\0&5\\7&-2\end{array}\right)[/tex]=  [tex]\left(\begin{array}{ccc}6&-9\\0&15\\21&-6\end{array}\right)[/tex]

Therefore the value of A+B is [tex]\left(\begin{array}{ccc}3&-3\\10&4.5\\10&-1\end{array}\right)[/tex] and the value of 3A is  [tex]\left(\begin{array}{ccc}6&-9\\0&15\\21&-6\end{array}\right)[/tex] .

To find the smallest positive value for x where y = sin^2x reaches its maximum, we can set sin^2x = 1 and solve for x. The smallest positive value of x where y = sin^2x reaches its maximum is pi/2.

To find the smallest positive value for x where y = sin^2x reaches its maximum, we need to consider the properties of the sine function. The sine function oscillates between -1 and +1, with the maximum value of sin^2x being 1. Since the maximum value of sin^2x is 1, we can set sin^2x = 1 and solve for x.

Applying the property of sin^2x = 1, we have:

sin^2x = 1
Taking the square root of both sides, sinx = ±1
Since we are looking for the smallest positive value of x, we take sinx = 1
This means that x = π/2 + 2πn, where n is an integer.

Therefore, the smallest positive value for x where y = sin^2x reaches its maximum is π/2.

The relation is not a function it is not a function because there are multiple y-values paired with a single x-value. Option B.

A relation is a function only if every input is mapped into a single output.

Here we have the relation {(3,7), (3,8), (3,-2), (3.4),(3,1)}

Remember that the first number of each pair is the input, so we can see that all the inputs are the same one

So the input x = 3 is mapped into different outputs, thus, this is not a function.

The correct option is B) it is not a function because there are multiple y-values paired with a single x-value.

To determine if a relation is a function, one must check if each x-value is associated with exactly one y-value. In other words, for every x, there should be one and only one y. This is known as the vertical line test in the context of graphs.

Let's examine the given set of ordered pairs: {(3,7), (3,8), (3,-2), (3,4), (3,1)}.

We can see that the x-value of 3 is repeated with different y-values: 7, 8, -2, 4, and 1.

This means that the x-value of 3 is associated with multiple y-values, which violates the definition of a function.

Therefore, the relation is not a function because it fails to satisfy the condition that each x-value must correspond to exactly one y-value.

The presence of multiple y-values for a single x-value is the key indicator that the relation is not a function.

Answer:

Step-by-step explanation:

Given: The equation [tex]9(u - 2) + 1.5u = 8.25[/tex]models the total miles Michael traveled one afternoon while sledding.

To Find: Which is the value of u?

Solution:

[tex]9(u - 2) + 1.5u = 8.25[/tex]

[tex]9u - 18+ 1.5u = 8.25[/tex]

[tex]10.5u = 8.25+18[/tex]

[tex]10.5u =26.25[/tex]

[tex]u =\frac{26.25}{10.5}[/tex]

Final answer:

To find the number n in the inequality '8 less than a number n is less than 11', we can set up and solve the inequality n - 8 < 11. The answer is that the number n is less than 19.

Explanation:

The question states that 8 less than a number n is less than 11. To solve this, we can set up the inequality:

n - 8 < 11

To isolate n, we can add 8 to both sides:

n < 11 + 8

n < 19

So, the answer is that the number n is less than 19.

The lines r and s are parallel

What are angles in parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.

We can conclude three factors determining parallel lines ,

Given data ,

From the figure m4 = m5

And , m4 and m5 are alternate angles

Alternate angles are angles that occur on opposite sides of the transversal line and have the same size

So , m1 = m5 are corresponding angles

Or angle 1 = angle 5

Corresponding angles are the pairs of angles formed on the same side of the transversal that are either both obtuse or both acute and are equal in size.

Similarly , m2 = m6 or angle 2 = angle 6

Hence , the lines r and s are parallel by the properties of angles in parallel lines.
