a trader buys 200 oranges for 60 kobo and sells them at 8 for 12 kobo.what is his gain
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let's solve ~
Cost price for each Orange :
[tex]\qquad \tt \dashrightarrow \: \dfrac{60}{200} [/tex]
[tex]\qquad \tt \dashrightarrow \:0.3 \: \: kobo[/tex]
Now, Cost price for 8 oranges :
[tex]\qquad \tt \dashrightarrow \:0.3 \times 8[/tex]
[tex]\qquad \tt \dashrightarrow \:2.4 \: \: kobo[/tex]
And we have been given that selling price for 8 oranges is 12 kobo.
Therefore, the gain is :
[tex]\qquad \tt \dashrightarrow \:12 - 2.4[/tex]
[tex]\qquad \tt \dashrightarrow \:9.6 \: \: kobo[/tex]
Percentage gain is ~
[tex]\qquad \tt \dashrightarrow \: \dfrac{9.6}{2.4} \times 100[/tex]

for the second pair of angles, the angle of reference is really about 26.57°. Now, the tangent is only negative in two quadrants, the II and IV Quadrants, using the angle of reference, it'd give us those angles.

Which is an equation of the line that passes through
the points (5, 2) and (10, -3)?
Answer:
y = -x + 7
Step-by-step explanation:
Hi there!
We are given the following points:
(5,2) and (10,-3)
We want to find the equation of the line that passes through these 2 points
There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b (m is the slope and b is the y intercept).
First, let's find the slope of the line.
The slope can be calculated from 2 points using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.
[tex]x_1=5\\y_1=2\\x_2=10\\y_2=-3[/tex]
Now substitute these values into the formula to find the slope
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-3-2}{10-5}[/tex]
Simplify
m=[tex]\frac{-5}{5}[/tex]
Divide
m=-1
The slope of the line is -1
We can substitute this value as m in y=mx+b.
Here's the equation of our line so far:
y=-x+b
Now we need to find b
As the equation passes through the points (5,2) and (10,-3), we can use either point to find the value of b
Taking (5,2) for example:
Substitute 5 as x and 2 as y
2=-5+b
Add 5 to both sides
7=b
Substitute 7 as b in the equation
y = -x + 7
Hope this helps!

Answer:
Yes
Step-by-step explanation:
There are two green regions and two red regions which makes four regions in total. If there is an equal probability to land on each region, it means that the probability to land on a green region is 2/4 because there are two green regions out of the four total regions. You could also simplify it to 1/2.

Wolves are a familiar animal in stories and movies. They are usually the bad animal. Some people think wolves are dangerous to people. But is this the truth? Wolves eat sheep and people don’t like that because they’re raising the sheep for themselves and some wolves can even take down cattle. Wolves make scary howls that can frighten people. But a sound can’t hurt you!
“You use the word “wolf” a lot. Can you find a more interesting way to say “wolf”?”
“I think wolves are scary, too. You’ll have to do more to convince me that they’re not!”
“I like your sentences about wolves, especially the ones where you describe how scary they are.”

I can't see the writing very clearly.
This is the correct solution:
27r^2 - 48 Divide through by 3:
= 3(9r^2 - 16) 9r^2- 16 is the difference of 2 squares so:

If tan (x) = 24/19 (in Quadrant 1), find
Give exact answers.
sin (x/2) =
cos(x/2) =
tan (x/2) =
If x is in quadrant I, then both sin(x) and cos(x) are positive. The angle x/2 also belongs to quadrant I, and hence each of sin(x/2), cos(x/2), and tan(x/2) are positive.
Recall that for all x,
cos²(x) + sin²(x) = 1
and multiplying through both sides by 1/cos²(x) = sec²(x) gives another flavor of this identity,
1 + tan²(x) = sec²(x)
It follows that
sec(x) = √(1 + tan²(x)) = √937/19
which immediately gives us
cos(x) = 19/√937
and from the identity above we find
sin(x) = √(1 - cos²(x)) = 24/√937
Recall the half angle identity for cos :
cos²(x) = (1 + cos(2x))/2
which means
cos(x/2) = + √[(1 + cos(x))/2] = √[1/2 + 19/(2√937)]
Then
sin(x/2) = + √(1 - cos²(x/2)) = √[1/2 - 19/(2 √937)]
and by definition of tan,
tan(x/2) = sin(x/2) / cos(x/2) = 1/12 √[649/2 - 19 √937/2]
Just to be clear, the solutions are
[tex]\cos\left(\dfrac x2\right) = \sqrt{\dfrac12 + \dfrac{19}{2\sqrt{937}}}[/tex]
[tex]\sin\left(\dfrac x2\right) = \sqrt{\dfrac12 - \dfrac{19}{2\sqrt{937}}}[/tex]
[tex]\tan\left(\dfrac x2\right) = \dfrac1{12} \sqrt{\dfrac{649 - 19\sqrt{937}}2}[/tex]
How do you find the mean (average) of a data set?
Answer:
To find the mean, you must add up all of the numbers in the data set and then divide them by the amount of numbers there are.
Step-by-step explanation:
For example:
1, 2, 3, 4, 5
To find the mean, we first add up all of these numbers:
1 + 2 + 3 + 4 + 5 = 15
Next, since there are 5 total numbers here, we divide their sum by 5:
15/5 = 3
That is how we get the mean (or average) of the data set.

Which function is the inverse of f(x) = -5x-4?
Answer:
B
Step-by-step explanation:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x5+45 f - 1 ( x ) = x 5 + 4 5 is the inverse of f(x)=5x−4 f ( x ) = 5 x - 4 .
Answer:
B. [tex]-\frac{1}{5} x+\frac{4}{5}[/tex]
Step-by-step explanation:
1. Rewrite the function as a linear equation:
y = -5x - 4
2. Swap x and y:
x = -5y - 4
3. Solve for y:
x+4 = -5y - 4+4
x + 4/-5 = -5y/-5
[tex]\frac{x+4}{-5}[/tex] = y can be rewritten as [tex]-\frac{1}{5} x+\frac{4}{5}[/tex]
4. Write in inverse notation:
f(x) = [tex]-\frac{1}{5} x+\frac{4}{5}[/tex]
Therefore, B is the answer.

A bird drops a stick to the ground from a height of 90 ft. The function h=16ft^2+90 gives the sticks approximate height h above the ground, in feet, after t seconds. At about what time does the stick hit the ground? How many seconds does it hit the ground?
Answer:
The stick hits the ground 2.37 seconds after it is dropped.
Step-by-step explanation:
Your function is incorrect.
I will assume that the correct function is
h = -16t² + 90
When the stick hits the ground, its height is 0.
We are looking for the value of t, time, when h = 0.
Set h = 0, and solve for t.
h = -16t² + 90
-16t² + 90 = 0
-16t² = -90
t² = 5.625
t = 2.37
The stick hits the ground 2.37 seconds after it is dropped.

What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
Avery leans a 24-foot ladder against a wall so that it forms an angle of 80° with the ground.
The height of the wall where the ladder reaches is given as,
sin 80° = h / 24
h = 24 x sin80°
h = 23.64 feet
The height of the wall where the ladder reaches will be 23.64 feet.

20. Joshua sold a batch of tickets for carnival rides. The ratio of adult
tickets to child tickets was 2:5. After he sold another 70 adult tickets and
300 child tickets, the ratio changed to 1:3. How many adult tickets did
Joshua sell in total?*
What is the awnser
Step-by-step explanation:
a = original number of adult tickets
c = original number of child tickets
a/c = 2/5
a = 2c/5
(a+70)/(c+300) = 1/3
(2c/5 + 70)/(c + 300) = 1/3
2c/5 + 70 = (c + 300)/3
2c + 350 = 5(c + 300)/3
6c + 1050 = 5(c + 300) = 5c + 1500
c = 450
a = 2c/5 = 2×450/5 = 2×90 = 180
Joshua sold therefore in total
180 + 70 = 250 adult tickets.
and by the way
450 + 300 = 750 child tickets.
