Answer:

how if there are no numbers or anything to find

Step-by-step explanation:

Answer:

A = 44º

[tex]b \approx 28.99[/tex]

[tex]c \approx 40.31[/tex]

Step-by-step explanation:

In this problem we are tasked with "solving the triangle," which means we need to solve for each of the triangle's non-given dimensions.

We can first solve for angle A, since we are given the other two interior angles of the triangle (90º and 46º), and we know that the measures of the interior angles of a triangle add to 180º.

A + 90º + 46º = 180º

A = 180º - 90º - 46º

A = 44º

Now that we have angle A, we can use the Law of Sines to solve for side length b.

[tex]\dfrac{a}{\sin(A)} = \dfrac{b}{\sin(B)}[/tex]

[tex]\dfrac{28}{\sin(44\textdegree)} = \dfrac{b}{\sin(46\textdegree)}[/tex]

[tex]b = \dfrac{28\sin(46\textdegree)}{\sin(44\textdegree)}[/tex]

[tex]b \approx 28.99[/tex]

Finally, we can solve for c using the Pythagorean Theorem.

a² + b² = c²

28² + 28.99² ≈ c²

[tex]c \approx \sqrt{1624.70}[/tex]

[tex]c \approx 40.31[/tex]

The linear equation for the given situation is y= cx + 2.50.

A linear equation is one that has the highest degree of 1 possible. This indicates that there are no variables in a linear equation with exponents greater than 1. Such an equation on the graph, forms a straight line.

We are given that a car service charges $2.50 to pick us up and charges c cents for each mile of our trip.

So, the equation that represent the cost of a car based on the number of miles driven is given by:

The number of games played is 6 and the number of rides is 2.

Here it is given that the number of games played was 3 times the number of rides. So, by this, we get the value of both is the ratio.

That is $15,

number of games played: number of rides = 3: 1

Let x be the common ratio. So, we have

Number of games played = 3x, and number of rides = x

It is given that the cost of each game is $1.50 and cost of each ride is $3 and the total cost is $15.

By this, we get an equation,

1.50 × 3x + 3 × x = 15

4.5x + 3x = 15

7.5x = 15

Answer: The quotient of 2 and 9 is 0.2222 (approximately) or 2/9

Step-by-step explanation:

Quotient is a mathematical term that refers to the result of dividing one number by another. In this case, the quotient of 2 and 9 is found by dividing 2 by 9, which results in 0.2222 (approximately) or 2/9.

It's important to note that the quotient is a decimal number because 9 doesn't divide into 2 exactly, so there is a remainder of 0.2222. The quotient represents the number of times 9 can be divided into 2, which is a fraction of a time. In this case, 9 can be divided into 2 only 0.2222 times.

I hope this helps :)

The quotient of 2 and 9 is the result of the division of 2 by 9 which is approximately 0.2222.

The question is asking for the quotient of 2 and 9. The quotient is the result of division. So, to find the quotient of 2 and 9, you need to divide two by nine.

The calculation is as follows: 2 ÷ 9 = 0.2222 (rounded to the fourth decimal place).

So, the quotient of 2 and 9 is approximately 0.2222.

Always remember, that when the divider (the number we divide by) is larger than the dividend (the number to be divided), we get a quotient less than one.

What is a system of equations?

A group of equations comprising one or more variables is known as a system of equations. The variable mappings that satisfy all component equations are the solutions to systems of equations.

Given equations : 2x + y = 10 .......equation 1

                             −x + 2y = 5 ......equation 2

Let's take the equation : 2x + y = 10

when x=0, y = 10 and when y=0, x=5

So, the first line passes through (0,10) and (5,0).

Now, If we look at second equation :   −x + 2y = 5

when x=0, y = 2.5 and when y=0, x= -5

So, the second line passes through (0,2.5) and (-5,0).

Now, we've −x + 2y = 5

we'll use substitution method to find out the intersection point.

multiplying it by 2, we get -2x + 4y = 10 ......equation 3

Adding equation 1 and 3,

we get, 5y = 20

             y = 4

Putting y = 4 in equation 3,

The probability of 3 or more deaf people are given as follows:

P(X >= 3) = 1 - P(X < 3).

In which:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).

Hence:

Thus:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

P(X < 3) = 0.1326 + 0.2707 + 0.2334

P(X < 3) = 0.6367.

P(X >= 3) = 1 - P(X < 3).

P(X >= 3) = 1 - 0.6367.

P(X >= 3) = 0.3633.

4000 donuts will Pamela need to sell in order to reach her goal.

What is the profit?

Profit is when the selling price is more than the cost price or revenue is more than the cost while loss is the opposite of profit.

To calculate the number of donuts Pamela needs to sell to reach her goal, you need to divide her desired profit by the profit per donut.

If the cost of ingredients for each donut is $0.67 and she plans to sell each donut for $2.99, the profit per donut would be $2.99 - $0.67 = $2.32.

To reach her goal of making at least 4000, she needs to make a profit of $2.32 x 4000 = $9280.

So she needs to sell $9280/$2.32 = 4000 donuts.

The probability of rolling two trick number cubes with the numbers 5, 10, and 15 on them can be calculated using the formula P(A) = n(A) / n(S), where P(A) is the probability of event A, n(A) is the number of favorable outcomes, and n(S) is the total number of possible outcomes.

In this case, the total number of possible outcomes is 6, since there are six possible combinations of two number cubes. The number of favorable outcomes for a sum of 10 is 2, since there are two possible combinations (5 and 5, and 10 and 15). Therefore, the probability of rolling a sum of 10 is 2/6, or one-third. The probability of rolling a sum of 15 is also one-third, since there is only one possible combination (10 and 5). The probability of rolling a sum of 20 is one-sixth, since there is only one possible combination (10 and 10). Therefore, the probability model for the sum of the two number cubes is a 2-column table with 3 rows. Column 1 is labeled Sum with entries 5, 10, 15. Column 2 is labeled probability with entries one-half, one-third, one-sixth.

Answer:

5.8%

Step-by-step explanation:

To find the average growth on Alexandra's total investment, we need to calculate the weighted average of the growth in each of the three investments. The weighted average is calculated by multiplying the growth of each investment by its proportion of the total investment and then adding them together.

First, we need to calculate the total amount of money that Alexandra invested. Since he invested 40% in mutual funds, 40% in real estate, and 20% in stocks, we can assume he invested $100.

So the amount invested in mutual funds is 40/100 * $100 = $40

The amount invested in real estate is 40/100 * $100 = $40

The amount invested in stocks is 20/100 * $100 = $20

Then we can calculate the growth of each investment using the percentages provided:

The growth of mutual funds is 2/100 * $40 = $0.80

The growth of real estate is 7/100 * $40 = $2.80

The growth of stocks is 11/100 * $20 = $2.20

Now we can add up the growth of each investment and divide it by the total investment to find the average growth:

($0.80 + $2.80 + $2.20) / $100 = $5.80 / $100 = 0.058 or 5.8%

So the average growth on Alexandra's total investment is 5.8%.
