The length of BC in the triangle ABC is 7.109.

What is the length of side?

Trigonometry is a branch of mathematics concerned with the study of triangles. It is commonly referred to as "trig" in a casual manner. Trigonometry examines how the sides and angles of triangles relate to one another.

Because the given triangle contains 90°, it is a right triangle.

Now, using the tangent function,

The tangent function is one of trigonometry's six primary functions.

Tan A = Opposite Side/Adjacent Side is the Tangent Formula. In terms of sine and cosine, tangent may be represented as: Tan A = Sin

then,

= tan B = opposite side / adjacent side

= tan 38° = AC/BC

= BC = 38° tan x AC

= BC = tan 38° × 9.1

= BC = 7.109

As a result, the length of the side BC is 7.109.

The possible length of the third side of the triangle is x>52 inches.

What is the sum of the first side and second side of any triangle?

The sum of the lengths of any two sides of a triangle is always greater than the length of the third side. If the sum of the two sides is equal to the third side, then the two sides will coincide with the third side so a triangle cannot be formed. Hence, the sum of the two sides must be greater than the third side for the triangle to be formed.

Given: Sides of two sides of a triangle as 15 and 37 inches.

Step-by-step explanation:

We have:

[tex][( \frac{1}{15} - \frac{2}{5}) * (-\frac{3}{4})^{3}] / (-9)[/tex]

Now, we will multiply the second fraction in the first parentheses by [tex]\frac{3}{3}[/tex] so we can subtract it from the [tex]\frac{1}{15}[/tex]. Then, we will multiply all of the [tex]\frac{3}{4}[/tex]'s. This gives us:

A line passes through the points (–1, –5) and (4, 5). the point (a, 1) is also on the line. a coordinate plane. what is the value of a? –2 –1 1 2

Answers

The value of a is 2

We can use the slope-intercept form of a line, y = MX + b, to find the equation of the line.

The slope (m) of the line can be found using the following formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

So, m = (5 - (-5)) / (4 - (-1)) = 10/5 = 2

Now, we can use the point-slope form of a line, y-y1 = m(x-x1)

where (x1,y1) is any point on the line and m is the slope of the line.

In this case, we will use the point (x1, y1) = (–1, –5)

so, y-y1 = m(x-x1) = -5 - 2(-1-x) = -5-2+2x

Now we know that the point (a,1) is also on the line, we can substitute the value of x and y in the equation

so, 1 - (-5) = 2(a - (-1))

1 +5 = 2a+2

6 = 2a+2

4 = 2a

a = 2

Therefore, the value of a is 2.

a rectangular room is 2 times as long as it is wide, and its perimeter is 36 meters. find the dimension of the room

Answers

The dimension of the room is width = 6 meters and length = 12 meters.

What is rectangle ?

A rectangle is a four-sided polygon with opposite sides that are parallel and of equal length. It has four right angles. The two parallel sides are called the length and the width. The length is the longer of the two sides, while the width is the shorter of the two sides.

Let's assume the width of the rectangular room is "w" and the length of the rectangular room is "l"

We know that the perimeter of a rectangle is the sum of twice the length and twice the width: P = 2l + 2w

Given that the perimeter is 36 meters, we can substitute that into the equation ,

36 = 2l + 2w

We also know that the length is 2 times the width, so we can substitute that into the equation: I = 2w

Now we have two equations ,

36 = 2(2w) + 2w

36 = 6w

So the width of the room is 6 meters. To find the length, we can use the information that the length is 2 times the width ,

l = 2w = 2*6 = 12 meters

So the dimension of the room is width = 6 meters and length= 12 meters.

A cell phone company charges 50$ for a phone plus 25$ per month. You get a gift card for 100$. When does the total spent on your phone service exceed the amount on you gift card?
A) Write an inequality to represent the money spent on a phone plan

B) when doe the total spent on your phone service exceed the amount of your gift card

Answers

Answer:

A) The money spent on a phone plan can be represented by the inequality:

50 + 25x > 100

B) The total spent on the phone service exceeds the amount of the gift card after the 2nd month.

Step-by-step explanation:

A. The inequality represents the total cost of the phone plan, where x represents the number of months for which the service is used.

The first part of the inequality, 50$, represents the initial cost of the phone.

The second part, 25x, represents the monthly cost of the service, 25$ per month.

So, the inequality represents the total cost of the phone plan as the sum of the initial cost of the phone and the monthly cost of the service for x number of months.

50 + 25x > 100

It states that the total cost (50 + 25x) of the phone plan is greater than 100$.

It's the total cost you have to pay for the phone and the service.

It's used to know when the total cost exceeds 100$, which is the gift card's value.

B. To find out when the total spent on the phone service exceeds the amount of the gift card, we can substitute in the inequality with the given values and solve for x.

50 + 25x > 100

x > (100-50)/25

x > 2

you have been told to reduce your department by 15%. your department has 220 workers. there are 512 workers in the whole company. how many workers must be let go (round to the nearest worker)?

Answers

To reduce your department by 15%, you would need to let go of 33 workers.

Reducing a department by 15% means that 15% of the current workforce in that department will be let go. To calculate this, you first need to determine the percentage of the total workforce that your department represents. In this case, your department has 220 workers out of 512 workers in the whole company, which represents 43% of the total workforce.

Then, you can calculate the number of workers that need to be let go by multiplying the total number of workers in your department by the percentage that needs to be cut. In this case, that would be

220 x 0.15 = 33 workers

This means that 33 out of the 220 workers in your department would need to be let go in order to achieve a 15% reduction.

Answers

The statistic that would not change if 50 points were added to each score in the SAT tests is the Standard Deviation.

What happens to the standard deviation ?

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean. By calculating the deviation of each data point from the mean, the standard deviation may be determined as the square root of variance.

The bigger the deviation within the data collection, the further the data points deviate from the mean; hence, the higher the standard deviation, the more dispersed the data.

Since they are used to determine standard deviation, sample size, mean, and data values all have an impact on standard deviation. By removing outliers, the sample size, mean, and standard deviation may all change.

Because 50 points was added to each score, they are still the same distance from each other which means the standard deviation will not change.

The given equation is y/ (y- 4) - 4/ (y + 4) = 32/ y

Let us simplify the left hand side (LHS) :

Make the denominator same to (y - 4)(y + 4)

y/ (y- 4) - 4/ (y + 4) = (y/ (y- 4))×((y + 4)/(y + 4)) - (4/ (y + 4))×((y - 4)/(y - 4))

y/ (y- 4) - 4/ (y + 4) = ( y(y + 4) - 4(y - 4))/ (y - 4)(y + 4)

y/ (y- 4) - 4/ (y + 4) = (y² + 4y - 4y + 16)/ (y² - 16)

y/ (y- 4) - 4/ (y + 4) = (y² + 16)/ (y² - 16)

Now plugging this simplified version in LHS

(y² + 16)/ (y² - 16) = 32/ y

y(y² + 16) = 32(y² - 16)

y³ - 32y² + 16y + 32×16 = 0

The solutions are approximately 30.948, 4.627 and -3.575.

What is equation?

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

x= total minutes -4    the 1st 4 minutes are included in the .30

total cost = .3 + .18 x  

[tex]3 = .3 +.18 x\\2.7 = .18x\\2.7/.18 = x\\15 = x[/tex]

x = total minutes -4

15+4 = total minutes
