Sara has 7,241 beads. She wants to make them into necklaces to sell at a charity fundraiser. She wants to use 13 beads on each necklace. How many necklaces is she able to make?

Answer:

y = 4

Step-by-step explanation:

note that the y- coordinates of the 2 points are equal, both 4

This indicates that the line passing through them is horizontal with equation

y = c ( c is the value of the y- coordinates the line passes through ), then

y = 4 ← equation of line

The equation of a line perpendicular to y = (-2/3)x - 7 is  y = (3/2)x + 17.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know lines perpendicular to each other have slopes that are negative reciprocals of each other.

So, the slope of the perpendicular line to the given line y = (-2/3)x - 7 is (3/2)

which passes through the point (-4, 11) is,

11 = (3/2)(-4) + b.

b = 11 + 6.

b = 17.

∴ y = (3/2)x + 17 is our required line.

Answer:

Step-by-step explanation:

9

The required product will be 6 when 9 is multiplied by 2/3.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

We have to determine whether the product will be between 2/3 and 9

As per the given question, we have

2/3 and 9

⇒ 2/3 × 9

Apply the multiplication operation,

⇒ 18/3

Reduce the above fraction into the simplest form, and we get

⇒ 6

Thus, the required product will be 6 between 2/3 and 9.

Inequality (C) -3.2 + 1.5n ≤ 8.6 correctly represents the sentence "the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6."

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.

Both mathematical phrases, equations, and inequalities are created by connecting two expressions.

The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.

The symbols >, <, ≤ or ≥ indicate that the two expressions in inequality are not always equal.

So, the sentence we have is:

the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6

Which can be written in inequality as:

-3.2 + 1.5n ≤ 8.6

Therefore, inequality (C) -3.2 + 1.5n ≤ 8.6 correctly represents the sentence "the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6."

Yes , there is convincing evidence that Brayden has improved his free-throw percentage when compared to previous year.

Brayden made 60 % free throws last year

P(Making  free throw last year) = 0.6

This year,

X% of 16 = 12

X/100 * 16 =12

75%

therefore, this year

P(Making  free throw this year) = 7.5

This clearly shows that he improved his free throw percentage compared to last year.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment.

Ayana lives 2952 feet away from his school and Eva lives 2000 feet away, Thus Eva lives closer to school.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

In India, Ayana lives 900 meters from his school,

And in United Sates Eva lives 2000 feet from her school.

Since,

1 meter = 3.28 feet

900 meter = 2952 feet

Here, distance of Ayana from her school is 2952 feet and distance of Eva from her school is 2000 feet.

Therefore, Eva lives closer to their school.

So the original equation is y=mx + b

And we know that each year the house increase by 5000, so the b is 5000

For the x which is the slope, we don't know what the slope is so we just say it as x and the ^x is for the number of years, let's say 3 years then it is ^3 and keep increasing like that up.

With $190, a maximum of 12 people can visit the theme park, where admission costs $15.25 per person and parking costs $7.

In mathematics, "inequality" refers to a connection between two expressions or values that are not equal to one another. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in lieu of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x values for which the inequality holds true is what we are most interested in.

Here,

The total amount they can spend=$190

Cost of parking=$7

Cost of ticket per person=$15.25

Let the number of person be x,

15.25x+7≤190

15.25x≤183

x≤12

There can be at most 12 person that can go to the amusement park with $190 where cost of tickets is $15.25 per person and cost of parking is $7.

None of the tables represent a proportional relationship.

Proportional relationships are those in which the ratios of two variables are equal. Another way to think about them is that one variable in a proportional relationship is always a constant value multiplied by the other. This is known as the "constant of proportionality."

To determine whether a relationship is proportional, examine the ratios between the two variables. The relationship is proportional if the ratio is always the same. The relationship is not proportional if the ratio changes.

Fir the first table, the ratio varies. Also, the second table isn't constant.

Therefore, none has a proportional relationship.
