Using the trigonometric ratios the correct option is option a) 4.98.

We have a known hypotenuse, but an unknown opposite side. Use the sine ratio to tie the two together to be able to solve for x.

Trigonometric ratios are a set of ratios that relate the angles of a right triangle to the lengths of its sides. The most commonly used trigonometric ratios are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively.

These ratios can be used to find missing side lengths or angle measures in a right triangle, and they have many applications in mathematics, physics, engineering, and other fields.

sin(angle) = opposite/hypotenuse

sin(50) = x/6.5

6.5*sin(50) = x

x = 6.5*sin(50)

x = 4.97928888027336, make sure your calculator is in degree mode

x = 4.98

Therefore, Using the trigonometric ratios the correct option is option a) 4.98.

The sum of numbers at B, C, D, E and F is 110.5

Since B, C, D, E, and F divide the segment AG into 6 equal pieces, each piece has a length of (59-13)/6 = 6.5.

Therefore, the numbers at B, C, D, E, and F are located at 13 + 6.5, 13 + 6.52, 13 + 6.53, 13 + 6.54, and 13 + 6.55 respectively.

The sum of the numbers at B, C, D, E and F is (13 + 6.5) + (13 + 6.52) + (13 + 6.53) + (13 + 6.54) + (13 + 6.55)

= 13 + 6.5*(1+2+3+4+5) = 13 + 6.5*15 = 13 + 97.5

The coating thickness distribution is normal and has a mean value of 1.245.

In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode.

To calculate the data's coating thickness, sample mean is employed.

The following formula is used to determine the mean value's point estimate:

[tex]\bar x = \frac{1}{n} \sum x_i[/tex]

The typical probability plot shown there has a rather straight pattern. Assume right now that the coating thickness distribution is normal and has a mean value:

The cloud can ascend 9,616 metres in 17.5 minutes, based on the statement made.

Utilizing the measurement of air pressure, altitude may be calculated. The pressure decreases with increasing altitude. An instrument is referred to as a pressure analyzer or pneumatic altimeter when a barometer is given a nonlinear calibration to display altitude.

This may be calculated by dividing the cloud's speed (552 metres per minutes) by the distance it must travel (17.5 minutes). We now know the distance to be 9,616 meters.

The speed of said cloud and the length of time it is going are four pieces of information that must be known in order to determine the minimum distance the cloud might cover in 17.5 minutes. We must increase the cloud's stated speed of 552 meters a minute by the distance it is going across, which in itself is 17.5 minutes. As a result, we now have 9,616 meters overall.

Another way to see this is to picture the cloud beginning at place A (9,200 meters) or terminating at point B. (9,616 meters). The distance between points A and B will be covered in 17.5 minutes if the cloud is moving at a pace of 552 meters per minute.

Step-by-step explanation:

a0 = 0 ft (starting on the ground)

a1 = a0 + 3 - 1 = a0 + 2

an = an-1 + 3 - 1 if an-1 +3 < 15

an = an-1 + 3 if an-1 + 3 >= 15

so, we need to find the n, so that

an = an-1 + 2 >= 12

but by looking at the structure, we see that every step just adds 2 ft to the total height.

an = a0 + 2n = 0 + 2n = 2n

2n >= 12

n >= 6

so, with day 6 the bug reaches 12 ft height. in day 7 it gets up to 15 ft and reached its goal.

it will take 7 days for the bug to reach the top and get the food.

The probability that the card is a face card (i.e., a jack, queen, or king) or a heart is 8/13

In the given question, suppose that you draw a card from a standard deck of cards.

We have to find the probability that the card is a face card (i.e., a jack, queen, or king) or a heart.

As we know that in a deck of cards have total 52 cards.

In which 26 cards are in heart shape.

Every different type of card have 3 face cards and have total four different type of cards. That means there are total 12 face cards.

In 26 cards of heart have total 6 face cards.

So, the probability that the card is a face card (i.e., a jack, queen, or king) or a heart

P = (Total face cards + total heart shape card - 6 face cards)/Total cards in a deck

P = (12 + 26 - 6)/52

P = (38 - 6)/52

P = 32/52

P = 8/13

Hence, the probability that the card is a face card (i.e., a jack, queen, or king) or a heart is 8/13.

The evaluation of the piecewise function gives:

when x = -3, f(x) = -4; when x = 2, f(x) = 0; and when x = 4, f(x) =  2.

when x = -3, w(x) = 2; when x = 2, f(x) = 5; and when x = 4, f(x) = 5

A piecewise function is a function that is defined by multiple sub-functions, each of which applies to a certain range of the input (or domain) values.

We want to evaluate the piecewise function when x = -3, x =2 and x = 4:

        { -4,   x < 2

f(x) = { x-2, -2 ≤ x≤ 4

         {0      x > 4

when x = -3:

f(x) = -4 because x < 2 (i.e. -3 < 2)

when x = 2:

f(x) = x-2

f(2) = 2-2 = 0

when x = 4:

f(x) = x-2

f(2) = 4-2 = 2

        { -x - 1,       x ≤ -3

w(x) = { 2x + 2,  -3 < x < 2

         {5,            x ≥ 2

when x = -3:

w(x) = -x - 1

So, the teacher can give out the jerseys in 840 ways.

The teacher wants to divide the 12 students into 3 teams, each with at least one girl and one boy.

One possible way to count the number of ways to divide the students is to use the stars and bars method.

For the first team, we have 5 stars and 2 bars, so the number of ways to pick 6 students is:

(5+2)!/(5!2!) = 7

For the second team, we have 4 stars and 1 bar, so the number of ways to pick 6 students is:

(4+1)!/(4!1!) = 5

For the third team, we have 3 stars, so the number of ways to pick 6 students is:

(3+0)!/(3!0!) = 4

Then we can multiply the number of ways to pick students for each team together to find the total number of ways to divide the students:

7 * 5 * 4 = 140

Then, as the jerseys are indistinguishable, we just have to multiply the number of ways to divide the students by the number of ways to distribute jerseys:

140 * 3! = 840

Therefore, the teacher can give out the jerseys in 840 ways.

The equation to determine how many bags Trisha brought is: T = 180 - (4 + 6)

We know that the total number of clementines is 180, Sal brought 4 bags and Joe brought 6. To determine how many bags Trisha brought, we need to determine the total number of bags that Sal and Joe brought together. We can do this by combining the two numbers together (4 + 6). This will give us a total of 10 bags. To determine how many bags Trisha brought, we need to subtract the total number of bags that Sal and Joe brought (10) from the total number of clementines (180). This gives us an answer of 170. This means that Trisha brought 170 clementines, or 7 bags. Therefore, the equation to determine how many bags Trisha brought is: T = 180 - (4 + 6).

If the owner of a pet food store wants to mix birdseed that cost $1.25 per pound with sunflower seeds that cost $0.75 . The number of pounds of each type of sea he should use is: 25 pounds of $1.25 birdseed and 25 pounds of $.75 sunflower seed.

Let x represent the number of  pounds of $1.25 birdseed that is is used

Combine like terms

.50x=50-37.5

Divide both side by .50x

x=12.5/.5

x=25 pounds of $1.25 birdseed

Step-by-step explanation:

Let x be the number of minutes of talk time used each month.

The cost for talk time beyond 500 minutes is $0.08 * (x - 500)

The cost for email is $27.70 * 0.3 = $8.31

The total monthly cost is $27.70 + $0.08 * (x - 500) + $8.31 = $35.99

The total cost for 9 months is $35.99 * 9 = $323.91

So we can set up the equation:

$27.70 + $0.08 * (x - 500) + $8.31 * 9 = $367.29

Solving for x, we get:

x = 567

So the number of minutes of talk time used each month is 567 minutes.

Investing is a smart way to put your money to work and could make you richer. If you make smart investing choices, your money may increase in value as outpace inflation. The major factors contributing to investment's increased growth potential are the possibility of compounding and the trade-off amongst risk and return.

Simple interest is calculated as follows: deposit amount multiplied by time and interest rate.

Let "a" represent the money placed in the account earning 3% interest.

Let's use the symbol to represent the amount deposited into the account earning 2.5% interest (10,000 - a)

a * 0.03 plus (10,000 - a) * 0.025 = 283

0.03a + 250 - 0,025a = 283

Collect like terms

0.03a - 0.025a = 283 - 250

0.005a = 33
