Step-by-step explanation:
So here...two triangle is measured in 78° and 30° ..here to find the value of third angle...
we need to subtract 180° from the sum of 78° and 30° ...cause the sum of all angle of triangle is 180° ..
x + 78° + 30° = 180°
x + 108° = 180°
x = 180° - 108°
x = 72°
hence the value of third angle is 72°....
From the diagram below, if
The possible values of x in the diagram are x = 25 and x = -1
How to determine the value of x?The given parameters are:
∠DAB = x² - 24x∠DAC = 25Both angles are congruent and adjacent angles.
So, we have:
∠DAB = ∠DAC
Substitute known values
x² - 24x = 25
Subtract 25 from both sides
x² - 24x - 25 = 0
Expand
x² + x - 25x - 25 = 0
Factorize
x(x + 1) - 25(x + 1) = 0
Factor out x + 1
(x - 25)(x + 1) = 0
Expand
x - 25 = 0 or x + 1 = 0
Solve for x
x = 25 or x = -1
Hence, the possible values of x are x = 25 and x = -1

The population of a certain city was 4001 in 1999. It is expected to decrease by about 0.37% per year. Write an exponential decay function, and use it to approximate the population in 2027
An exponential decay function, and use it to approximate the population in 2027 is P(t) = 4001e^-(0.0037)(28) = P(t) = 4001e^-0.1036
Exponential equationThe standard exponential function is expressed as:
P(t) = P0e^-rt
P0 is the initial population = 4001r is the rate. = 0.37% = 0.0037t is the timeSubstitute
P(t) = 4001e^-(0.0037)t
If t = 28 (by 2027)
An exponential decay function, and use it to approximate the population in 2027 is P(t) = 4001e^-(0.0037)(28) = P(t) = 4001e^-0.1036

Answer:

Step-by-step explanation:
x+2y=82........(1)
3x+y=96.........(2)
y=96-3x...........(3)
x+2y=82
x+2(96-3x)=82
x+192-6x=82
-5x=82-192
-5x=-110
x=-110÷-5
x=22
y=96-3x
y=96-3(22)
y=96-66
y=30
Therefore,x=22 and Y=30

Determine whether 5, 238 is divisible by 2, 3, 4, 5, 6, 9, or 10.
Answer:
2, 3, 6
Step-by-step explanation:
Simply try each value using long division.
2:
Since 5,238 ends in an even number, that automatically means it is divisible by 2.
5238/2=2619
Now for 3:
5238/3=1746 no remainder or decimal, so 3 also works
4:
You can either do long division again with 4, or you can see if 5238 divided by 2 (5238/2) is also divisible by 2. Since 2619 doesn't end in an even number, 4 is a no go.
Long division 5238/4=1309.5 decimal here, so 4 isn't an answer
5:
This is also very easy, simply check if the number ends in 0 or 5. Since 5,238 does not, 5 doesn't work either.
6:
You can do the same thing as with 4, except this time trying to find if 5238 divided by 3 (5238/3) is divisible by 2. Since 1746 ends in an even number, 6 also works.
Long division: 5238/6=873
9:
You can do the same thing as with 6, except this time trying to find if 5238 divided by 3 (5238/3) is divisible by 3.
1746/3=548 with a remainder of 2, which means 9 doesn't work
Long division: 5238/9=548.66 repeating
10:
Finally, 10 is another easy one. Simply check if the number ends in 0. 5,238 does not, so 10 doesn't work.
At a highschool in a class of 235 students, 90 pass Mathematics, 85 pass English and 78 pass both courses. What’s the probability that a random student passed either Mathematics or English or both? ((Union question)
Answer:
41.3%
Step-by-step explanation:
The probability of interest is found by dividing the number of students passing either course by the total number of students.
The number passing only one of the courses is the number passing that course, less the number passing both courses. This is shown in the attached 2-way table.
__
The number passing either course will be the sum of the number passing one course (including the number passing both courses), and the number passing only the other course. It can also be found as the sum of the numbers passing either course, less the number passing both courses (since the latter would be counted twice).
Here those passing either (or both) Math or English will be ...
90 +(85 -78) = 85 +(90 -78) = (90 +85) -78 = 97
So, the probability is ...
p(passing either M or E) = 97/235 = 0.41277 ≈ 41.3%

Answer:
B. y=-0.5x + 1
Step-by-step explanation:
first look at the slope: slop = rise over run. for every 2 units right, the point goes 1 unit down. so the slope if -1/2 or -0.5
next look at the y-intercept. the y-intercept of this graph is 1
plug these into the equation y= mx + b to get y = -0.5x + 1
Answer:
A. y = -0.5x + 1
Step-by-step explanation:
Hello!
An equation of a line is written in slope-intercept form: [tex]y = mx + b[/tex]
y = output, y-value, ordinatem = slope, rise over run, rate of changex = input, x-value, abscissab = y-intercept, starting valueY-interceptThe y-intercept is found when x=0, or then the line crosses the y-axis.
Over here, we can see that the line crosses the y-axis at point (0,1), so the y-intercept is positive 1.
SlopeSlope is calculated by rise over run, or the ratio of how much the graph rises over how much the graph runs. Use points to determine how the graph changes. (For simple calculations, use integer points, such as (0,1) and (0,2)
[tex]\frac{\text{rise}}{\text{run}}[/tex][tex]\frac{-1}{2}[/tex][tex]-0.5[/tex]Now that we have the slope and the y-intercept, we can plug those values to make our equation.
[tex]y = mx + b[/tex][tex]y = -0.5x + 1[/tex]The correct answer is Option A. y = -0.5x + 1

In South Africa, musicians who perform along the streets are called buskers, and must get a permit, which costs $30. They can make an average of $45 per night (n), depending on the area. Some choose not to get this permit, but need to stay in less populated areas in order to not get caught without a permit so they may only make an average of $15 per night. How many nights of work would have the performers making an equal amount total?
The number of night of work each performers will have equal amount is 1 night
How to find the time of work that the performers will have equal amount?The buskers gets permit which cost $30. They can make an average of $45 per night (n),
Therefore,
y = 45n - 30
Without a permit they may only make an average of $15 per night.
Therefore,
y = 15n
The number of night the money made are both equal.
45n - 30 = 15n
45n - 15n = 30
30n = 30
n = 30 / 30
n = 1
Therefore, the number of night of work each performers will have equal amount is 1 night

All circles are similar because radius is constant throughout the circle.
What is similarity of circles?Every point on a circle's perimeter is equidistant from its center. We utilize the radii to get the scale factor since the size of each circle is specified by its radius.
A quality of at least two forms in relation to each other is similarity. When two forms are similar, their qualities in relation to one another remain the same.
A circle is characterized by two properties: its center and radius.Because similarity is unaffected by location the similarity of circles is solely determined by their radii.
Hence,all circles are similar because radius is constant throughout the circle.
