points b , c and d lie on a straight line
AC is perpendicular to BD
BC=6cm and BD=22cm
triangle ABC has an area of 42
calculate the size of angle x
Step-by-step explanation:
To Find : size of angle x
Solution:
Area of ΔABC = (1/2) * BC * AC
=> (1/2) * BC * AC = 42
=> (1/2) * 6 * AC = 42
=> AC = 14 cm
BD = BC + CD
=> 22 = 6 + CD
=> CD = 16 cm
Tan x = AC /CD
=> Tan x = 14/16
=> Tanx = 7/8
=> x = Tan⁻¹(7/8)
=> x = 41.186°
The size of the angle is - 41. 186°
Points b,c, and d lie in a straight line. AC is perpendicular to BDBC = 6 cm, BD = 22 cm. Triangle ABC has an area of 42cm². the size of the angle = xarea of triangle ABC = 1/2 * BC * AC
or, 1/2 *BC * AC = 42
or, 1/2 * 6 * AC = 42
or, 3 * AC = 42
divide both sides by 3,
AC = 14 cm
BD = BC + CD
or, 22 = 6 + CD
or, CD = 16 cm
tan x = [tex]\frac{AC}{CD}[/tex]
or, tan x = [tex]\frac{14}{16}[/tex]
or, tan x = [tex]\frac{7}{8}[/tex]
or , x = 41. 186°
∴ The size of the angle is - 41. 186°.

The minimum value, Q1, Median, Q3 and maximum value of the data are 10,15,21.5, 23.5 and 27 respectively. The box-and-whisker plot of data is attached
How to make a box-and-whisker plot of data?Given: 21,27,22,22,25,14,16,10
Arrange the data in ascending or descending order:
10,14,16,21,22,22,25,27
The minimum value = 10. The maximum value = 27
Find the median. The median is the value in the middle. The median values are 21 and 22. Thus:
10,14,16,21,22,22,25,27
Median (Q2) = (21+22)/2 = 21.5
Consider the values to the left of the median with one of the median numbers included (since we have two numbers in the middle): 10,14,16,21
Median = (14+16)/2 = 15
Thus, Q1 = 15
Also, consider the values to the right of the median with one of the median numbers included: 22,22,25,27
Meadian = (22+25)/2 = 23.5
Thus, Q3 = 23.5

The cylindrical coordinates of (−7, 7, 7) are (√98, -π/4, 7). cylindrical coordinate (−7, 7 3 , 1) is (14, -π/3, 1).
We must switch from rectangular to cylindrical coordinates in the provided problem. (let r ≥ 0 and 0 ≤ θ ≤ 2π.)
A)(−7, 7, 7)
Given rectangular coordinates(x, y, z) =(−7, 7, 7)
The cylindrical coordinates are (r, θ, z)
As a result, we determine each value of r and θ separately.
r = √x²+y²
r = √(-7)²+(7)²
r = √49+49
r = √98
θ = tan⁻¹ (y/x)
θ =tan⁻¹ (7/-7)
θ =tan⁻¹ (-1)
θ = -π/4
So cylindrical coordinate = (r, θ, z) = (√98, -π/4, 7)
B) (-7,7√3,1)
Given rectangular coordinates(x, y, z) = (-1,1,1)
The cylindrical coordinates are (r, θ, z)
As a result, we determine each value of r and θ separately.
r = √x²+y²
r = √(-7)²(7√3)²
r = √49+147
r = √196
r = 14
θ = (y/x)
θ = (7√3/-7)
θ = (-√3)
θ = -π/3
So cylindrical coordinate = (r, θ, z) = (14, -π/3, 1)

of the function the smallest?

Y

40
Answer:
The x-axis interval of 39 to 65 has the smallest rate of change.
Step-by-step explanation:
See the attached worksheet. The interval of x that results in the least change in y can be visually seen by plotting the points and drawing a curve. The curve begins to flatten as x increases. So the smallest rate of change is between the last two points, x = 39 to 65.
This can also be calculated by finding the change in y per a change in x. The table in the graph confirms the earlier observation. Dx and Dy represent the "delta," or difference, D, between the x (Dx) and y(Dy) values. The rate of change is calculated as Dy/Dx, or the change in y divided by the change in x. The results confirm that the 39 to 65 segment is the smallest, at 0.15.

high school has 36 players on the football team. the summary of the players' weights is given in the box plot. how many players weigh between 169 and 194 pounds?
There are 8 players who weigh between 169 and 194 pounds.
To answer this question, we can look at the box plot to understand the distribution of weights on the football team. The box plot shows us the minimum, maximum, median, and quartiles of the team's weights. The left quartile is 169 pounds, and the right quartile is 194 pounds. This means that 25% of the team's players weigh between 169 and 194 pounds. Since the team has 36 players, 25% of 36 is 9. However, since we are looking at the number of players between 169 and 194 pounds, we need to subtract 1 since the right quartile of 194 pounds is included in the number of players. Thus, there are 8 players who weigh between 169 and 194 pounds.

Question 2
Matilda needs at least $112 to buy a new dress. She has already saved $40. She earns $9 an'hour babysitting. What is the solution of the
inequality that determines how many hours she will need to babysit to buy the dress?
Let x represent the number of hours Matilda babysits.
Answer: x ≥ 8
Step-by-step explanation:
We know that our inequality must be greater than or equal to $112 because she needs at least $112 to buy the new dress. This is the first part of our inequality.
Next, we see that she already has $40 and will earn $9 an hour babysitting, if x is the number of hours. $9 an hour can become 9x, then we will add the $40 she already has for 9x + 40 as the second part of our inequality.
This complete inequality is:
9x + 40 ≥ 112
Now, we can solve by isolating the variable x with inverse operations.
9x + 40 ≥ 112
9x ≥ 72
x ≥ 8
Matilda needs to babysit at least 8 hours to afford the new dress.

Ms. Jones washed most of the laundry and the remaining laundry need to be washed is 7/20.
Converting the fraction to decimal to easily compare the amount of laundry washed.
Laundry washed by Ms. Jones = 2/5
Performing division
Laundry washed by Ms. Jones = 0.4
Laundry washed by her son = 1/4
Performing division
Laundry washed by her son = 0.25
0.4 is greater than 0.25, hence, Ms. Jones washed more laundry.
They washed the laundry in fractions. So, the total laundry can be taken as 1.
Total laundry washed = 0.4 + 0.25
Total laundry washed = 0.65
Remaining laundry = 1 - 0.65
Performing subtraction
Remaining laundry = 0.35
Converting into fraction = 35/100
Remaining laundry in fraction = 7/20
