In isosc tri(ABC),AC=BC,AB=6 in., line segment cd is parrelel to line segment ab, and CD= sqrt(3) in find the perimeter of the isosc triangle

Answer:

8.25 gallan=33 quart

Step-by-step explanation:

The perimeter of each shape is obtained adding all of their outer side lengths.

The perimeter of a polygon is composed by the sum of the lengths of the outer edges of the figure.

Hence, for each polygon, you must identify the outer side lengths, and then add them.

The problem is incomplete, hence the standard procedure to find the polygon of a shape was presented.

The required measure of angle p in triangle DBC is given as ∠p = 59.14°.

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,

Consider triangle ABD

Apply the Pythagorean theorem to determine the measure of DB,
DB² = AD² + AB²
DB² = 6² + 5²
DB² = 61
DB = 7.81

Now,
Apply the trig ratio in triangle DCB,
cosp = 4/7.81
p = 59.14°

Thus, the required measure of angle p in triangle DBC is given as ∠p = 59.14°.

Answer:

Step-by-step explanation:

5 times -4 is -20, so the equation becomes -20 - r + 1 = -37

-20 plus 1 equals -19, so the equation is now -19 - r = -37

Then you add 19 to both sides to isolate r

-r = -18

To get a positive r, divide or multiply both sides by -1, and you get r = 18

[tex]5(-4)-r+1=-37[/tex]

Simplify:

[tex]-20-r+1=-37[/tex]

Combine Like Terms:

[tex](-r)+(-20+1)=-37[/tex]

[tex]-r-19=-37[/tex]

Add 19 to both sides:

[tex]-r-19+19=-37+19[/tex]

[tex]-r=-18[/tex]

Divide both sides by -1:(To remove the negative from the variable r)

[tex]\dfrac{-r}{-1}=\dfrac{-18}{-1}[/tex]

[tex]\boxed{r=18}[/tex]

Answer:

0.209.

Step-by-step explanation:

The probability that someone files their taxes on time is 1 - 0.351 = 0.649.

To find the probability that 6 out of 10 people file their taxes on time, we can use the binomial distribution. The binomial formula for the probability of k success in n trials is given by:

P(k) = (n choose k) * p^k * (1-p)^(n-k)

Where (n choose k) is the number of combinations of n items taken k at a time, and p is the probability of success in a single trial.

So, for the problem at hand:

P(6) = (10 choose 6) * 0.649^6 * (1 - 0.649)^(10 - 6) = 0.209

Therefore, the probability that 6 out of 10 people file their taxes on time is approximately 0.209.

To sketch the angle θ in standard position, you can start by plotting the point ( -3, 4 ) on the coordinate plane. Next, you draw a line from the origin ( 0, 0 ) to the point ( -3, 4 ), which represents the terminal side of the angle.

Now, you can use the six trigonometric functions to find the exact values for θ:

Cosine ( cos θ ) = x / r = -3 / 5

Sine ( sin θ ) = y / r = 4 / 5

Tangent ( tan θ ) = y / x = 4 / -3

Secant ( sec θ ) = 1 / cos θ = -5 / 3

Cosecant ( csc θ ) = 1 / sin θ = -5 / 4

Cotangent ( cot θ ) = 1 / tan θ = -3 / 4

Here, r represents the distance from the origin to the point ( -3, 4 ), which is 5 units. Note that these values are for the least positive measure of the angle, which is in the second quadrant.

Answer: The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces a valid output (y-value).

In this case, the function s(x) = 6/25 - x^2 has no restrictions on the input values for x, so the domain of the function is all real numbers.

Therefore, the domain of the function s(x) = 6/25 - x^2 is:

(-∞, ∞)

This means that the function can be evaluated for any real value of x.

For part a:

Mean: Use the AVERAGE function to find the mean of the "Number" column.

Median: Use the MEDIAN function to find the median of the "Number" column.

Mode: There is no built-in function to find the mode in Excel, but you can use a combination of the IF, COUNTIF, and MAX functions to find the most frequently occurring value.

Maximum: Use the MAX function to find the maximum value in the "Number" column.

Minimum: Use the MIN function to find the minimum value in the "Number" column.

For part b:

Mean: Use the AVERAGE function to find the mean of the "Percent" column.

Median: Use the MEDIAN function to find the median of the "Percent" column.

Mode: There is no built-in function to find the mode in Excel, but you can use a combination of the IF, COUNTIF, and MAX functions to find the most frequently occurring value.

Maximum: Use the MAX function to find the maximum value in the "Percent" column.

Minimum: Use the MIN function to find the minimum value in the "Percent" column.

For part c:

The statistics on children whose parents do not have secure employment provide important insights into the state of the economy. In this case, the mean and median of the number of children in each state seem to be around 450,000. The mode cannot be determined since there are no repeated values in the "Number" column. The maximum number of children is 678,000 in Ohio, while the minimum number is 141,000 in Iowa.

Comparing the states, Indiana has a slightly higher mean and median percent of children whose parents do not have secure employment at 27%, compared to the other surrounding states which range from 20% to 31%. However, there is no clear state with the best or worst data as the range of the percent values is not too wide.

In terms of comparison, the number of children may provide a more comprehensive understanding of the extent of the problem, as it gives a clearer picture of the actual number of children affected. However, the percentage provides a more relative comparison between the states, allowing for easier comparison and a clearer understanding of the proportion of children affected in each state.

Answer:

Step-by-step explanation:

To determine which option is faster, we need to determine the total number of nights required for each option.

First, let's find the number of pages Nora still needs to read by subtracting the number of pages she's already read from the total number of pages: 280 pages * 30% = 84 pages

So, Nora still needs to read 280 pages - 84 pages = 196 pages.

For Option 1, Nora would read 25% of the remaining pages each night, so the number of pages she reads each night would be: 196 pages * 25% = 49 pages

The total number of nights required would be 196 pages / 49 pages/night = 4 nights.

For Option 2, Nora would read 28 pages each night, so the total number of nights required would be 196 pages / 28 pages/night = 7 nights.

Since 4 nights is less than 7 nights, Nora should choose Option 1 to finish reading the book in the least amount of time.

On solving the provided question, we can say that by linear equation If The Grant is thinking of two numbers, they are 13 and 26.

A linear equatiοn is one that has the form y = mx+b in algebra. B is the slοpe, and m is the y-intercept. It's usual to refer tο the previous clause as a "linear equation with twο variables" because y and x are variables. The twο-variable linear equations knοwn as bivariate linear equations.

There are several instances οf linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. It is referred tο as being linear when an equation has the fοrm y = mx+b, where m stands for the slοpe and b for the y-intercept. When an equatiοn has the formula y = mx+b, with m denοting the slope and b the y-intercept, it is referred tο as being linear.

x be the first number and y be the secοnd number:

x = 2y

x + y = 39

Plug x = 2y in the other equation:

2y + y = 39

3y = 39

y = 13

x = 26

If The Grant is thinking of two numbers, they are 13 and 26. He claims that the total of the two numbers is 39 and that one of the numbers is double the other.
