Can you find the measure of the indicated angle and type the correct code? Please remember to type in ALL CAPS with no spaces,
Answer:
hey I need this answer and puzzle 4 and 5 you got these things?
Step-by-step explanation:
please
The measure of angles A, B , C and D°are 36°, 63°, 71° and 111° respectively
How to determine the measure of the indicated angle?
To find the measure of angles of A, B, C and D, you need to apply some of the angle geometry concepts as follows:
1. m<A
(x+24)° and A = 3x
Since alternate angles are equal, thus:
3x° = (x+24)°
3x -x = 24
2x = 24
x =24/2 = 12
Also, A = 3x = 3(12) = 36°
2. m<B
B = 10x-27 and 7x
Since corresponding angles are equal, thus:
10x -27 = 7x
10x -7x = 27
3x = 27
x = 27/3 = 9
Also, B = 10x -27 = 10(9) -27 = 90-27 = 63°
3. m<C
C = (5x+1)° and (6x-13)°
Since corresponding angles are equal, thus:
(5x+1)° = (6x-13)°
6x -5x = 13+1
x = 14
Also, C = 5x+1 = 5(14) + 1 = 70+1 = 71°
4. m<D
(6x+3)° and D = (4x+39)°
Since alternate angles are equal, thus:
6x+3 = 4x+39
6x-4x = 39-3
2x=36
x = 36/2 =18
Also, D = 4x+39 = 4(18) + 39 = 72+39 = 111°
Therefore, the m<A = 36°, m<B = 63°, m<C = 71° and m<D =111°. Since B, A, H and E correspond to m<A, m<B, m<C and m<D respectively, so type BAHE in the answer box

Range=
Domain=
Answer:
Range: [tex]\text{y} \ge 0[/tex]
Domain: [tex]\text{x} \ge 0[/tex]
Both involve "greater than or equal to 0".
==============================================
Explanation:
The domain is the set of allowed inputs (x). The smallest input allowed in this case is x = 0, as it corresponds to the left-most point (0,0) on the blue graph. There is no largest x value since it stretches forever to the right.
Either x = 0 or x > 0 which condenses to [tex]\text{x} \ge 0[/tex] and this is the domain as an inequality.
--------
The range will have us look at the possible y values or possible outputs. We have y = 0 as the smallest output possible, which corresponds to the lowest point (0,0).
There is no largest y value since the blue graph goes forever upward.
Either y = 0 or y > 0 to give us the range of [tex]\text{y} \ge 0[/tex]
A seamstress usually sews 55 pieces per day. on a certain day,
she sews 77 pieces. what is the percent increase in the number
of pieces she sews on that day?
The percentage increase in the number of pieces she saws on that day is 40%.
Here it is given that a seamstress sews 55 pieces per day.
But on a certain day, 77 pieces were sewn.
We have to find the percentage increase in the number of pieces she sews on that day.
So first we have to find the increase in the number of pieces she sews.
Increase in the number = 77 - 55
= 22
The original number per day = 55
Formula to find the percentage increase in the number.
Percentage increase = Increase in number/ original number × 100
Now putting the values in the equation:
Percentage increase = 22 / 55 × 100
= 2/5 × 100
= 40%
Therefore there is a 40% increase in the number of pieces.

When the p-value is used for hypothesis testing, the null hypothesis is rejected if?.
The null hypothesis is rejected if the p-value is lower than or equal to the chosen significance threshold; otherwise, it is not. To put it another way, if p, reject [tex]H_{0}[/tex]; if p>, do not reject [tex]H_{0}[/tex].
This criterion, known as (alpha) in null hypothesis testing, is often set to 05. The rejection of the null hypothesis is if there is less than a 5% probability that a result as dramatic as the sample result would occur if the null hypothesis is accepted. The outcome is referred to as statistically significant when this occurs.
If a statistical test is run with a threshold of significance = 0.1, 0.05, and 0.01 the null hypothesis was rejected.
The alternative hypothesis is taken into consideration instead of the null hypothesis if the P value is less than alpha, the predetermined level of statistical significance.

If applicable, give the solution.
What is an equation of the line that passes through the points (4, -2) and (2, 3)
The slope-Intercept form of the given line is y=1.5x.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
The given line passes through (4, -2) and (2, 3). Therefore, the slope of the given line can be written as,
Slope of the line, m = (-2 - 3)/(4 - 2)
= 3 / 2
= 1.5
Now, the equation of the line passing through (2, 3) can be written as,
y = mx + c
(3) = 1.5(2) + C
3 = 3 + C
3 - 3 = C
C = 0
Substitute all the value in the equation of the line,
y = m(x) + c
y = 1.5(x) + 0
y = 1.5x
Hence, the equation of the given line is y=1.5x .

the probability that jacie will eat cheese on any given day is 0.6 while the probability that robyn will eat cheese on any given day is 0.25. if these events are independent, what is the probability that jacie or robyn will eat cheese on a randomly selected day?
The probability for Jacie or Robyn would consume cheese on a random day is 0.15.
What is defined as the independent events?Two occurrences are considered independent if indeed the occurrence of one does not alter the likelihood of the occurrence of the other. The mathematical expression of event independence A and B is the chance of both A and B occurring being equal to the sum of both the probabilities of both B and A (i.e., P) (A and B).The likelihood of Jacie eating cheese on any particular day is 0.6.
The likelihood of Robyn eating cheese on any particular day is 0.25.
Both events are independent.
As a result, the probability for Jacie or Robyn would consume cheese on a random day is;
P(Jacie or Robyn) = P(Jacie). P(Robyn)
P(Jacie or Robyn) = 0.6 x 0.25
P(Jacie or Robyn) = 0.15
Thus, the probability for Jacie or Robyn would consume cheese on a random day is 0.15.

Our school flag is a rectangle. We are changing to a new rectangular flag design. The length of the new flag is 20% greater than the length of the old flag, and the width of the new flag is 10% less than the width of the old flag, The old school flag is 25 square feet. What is the area of the new flag?
Answer: Hence the answer is 27 square feet.
Please look at the images for more details.
Answer:
27 square feet
Step-by-step explanation:
Define the variables:
Let w be the width of the old flag.Let l be the length of the old flag.To increase a number by a certain percent, divide the percent by 100, add it to 1, then multiply the original number by this number.
If the length of the new flag is 20% greater than the length of the old flag:
[tex]\implies \textsf{Length}=\left(1+\dfrac{20}{100}\right) \timesl \times l=1.2l[/tex]
To decrease a number by a certain percent, divide the percent by 100, subtract it from 1, then multiply the original number by this number.
If the width of the new flag is 10% less than the width of the old flag:
[tex]\implies \textsf{Width}=\left(1-\dfrac{10}{100}\right) \times w =0.9w[/tex]
[tex]\boxed{\textsf{Area of a rectangle}=\sf width \times length}[/tex]
Therefore, given the area of the old flag is 25 ft²:
[tex]\implies wl=25[/tex]
To find the area of the new flag, substitute the expressions for width, length and wl into the formula for area of a rectangle:
[tex]\begin{aligned}\textsf{Area of new flag}&=\sf width \times length\\&=0.9w \times 1.2l\\&=0.9 \times 1.2 \times wl\\&=1.08 \times 25\\&=27\sf \;\; ft^2\end{aligned}[/tex]
Therefore, the area of the new flag is 27 square feet.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , let the side be represented as BD , which cuts AC at point D
And , the measure of BD = measure of DC ( given )
And , the measure of ∠ABC = 90°
The measure of ∠BDA = 40°
So , the measure of angle ∠BDC = 140° ( angles on a straight line )
Now , the measure of angle ∠DBC = measure of ∠BCD ( given )
So , the measure of x = ( 180 - 140 ) / 2
x = 20°
And , the measure of y = 180° - 40° - 70°
y = 70°
Hence , the angles of triangle are x = 20° and y = 70°
