Hello :D
The pen is 9 2/5 rupees and the pencil is 3 1/5 rupees. To work this out we need to subtract them from each other.
9 2/5 - 3 1/5 = 6 1/5 rupees.
The pen cost more by 6 1/5 rupees.
I hope this helps and I would appreciate it, if you could give me brainliest
1. Solve the system using elimination.
3x - 4y = 9

Find cos(a) Reduce the ratio if necessary
Answer:
3/5 Choice 4.
Step-by-step explanation:
Remember SOH, CAH, TOA.
Sine=opposite/hypotenuse
Cosine=Adjacent/hypotenuse
Tangent=Opposite/adjacent.
Since we are looking for Cosine, we would need to locate the adjacent and hypotenuse of angle a.
The hypotenuse is the easiest to find because that will simply be the longest side of the triangle(50)
The adjacent would be 30 because 40 is the opposite(right across from theta).
So, A=30
H=50
Simply that to get Cos(A)=[tex]\frac{3}{5}[/tex].

Part B If Ivy conducted her survey of 25
students on a volunteer basis, are the
results representative of the school?
Why or why not?
Answer:
Step-by-step explanation:
No, the results are not necessarily representative of the school as a whole.
What is the random survey?A random survey is a research technique that is used to gather information from a sample of people or things in a population. The results of a random survey are more likely to be representative of the population as a whole since every member of the population has an equal chance of being chosen to take part in the research.
Given:
Ivy randomly surveys students in her school to learn more about mobile phone password use.
Of 25 respondents, 14 use a password.
If the survey was conducted on a volunteer basis, it is possible that the respondents who chose to participate may have different characteristics or behaviors than those who did not participate.
This could lead to a biased sample that does not accurately represent the entire school population.
Additionally, even if the sample is representative of the school population, a sample size of 25 is relatively small, which can increase the margin of error and make it more difficult to draw accurate conclusions.
Therefore, it is important to consider the limitations of the survey method and sample size when interpreting the results.

If the composition of two functions is:
1/x−3
What would be the domain restriction? Describe how you found that answer.
9514 1404 393
Answer:
x ≠ 3
Step-by-step explanation:
In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.
The domain is all real numbers except x=3.
_____
Additional comments
It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.

Which statements include two quantities in the real world that are additive inverses?
Select each correct answer.
1. Daniella overdraws her account by $70 and then deposits $100 in the account.
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
3. A lithium ion has 3 positively charged protons and 2 negatively charged electrons.
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
There are two statements here, showing quantities in real world which are additive inverse of each other :
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
here, we can depict going up as +2 miles and going down the trail as -2
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .
Answer:
The options are (2) and (4).
Step-by-step explanation:
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
→ Up 2 mi (+2) and down 2 mi (-2).
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
→ Here they are, ascends 2000 ft (+2000) and descends 2000 ft (-2000).

there was a vote at a local school to determine a new logo. You are told 7% of the students wanted to keep the old logo, and that 7% represents 1,400 students at the school. how many students are at the school?
Step-by-step explanation:
Let the number of students be x,
Now,
7% of x = 1400
or, 7/100 X x = 1400
or, x = 1400 x 100
—————
7
or, x = 140000/ 7
or, x = 20000
Thus, there are 20,000 students

please show work 7r + 21 = 49r
Answer:
1/2 = r
Step-by-step explanation:
7r + 21 = 49r
Subtract 7r from each side
7r-7r + 21 = 49r-7r
21 = 42r
Divide each side by 2
21/42 = 42r/42
1/2 = r
Answer:
r = 0.5
Step-by-step explanation:
First you need to isolate the r variable.
7r + 21 = 49r
-7r -7r
21 = 42r
Then Divide both sides by 42
0.5 = r
Now check your answer by inserting it back into the original equation.
7(0.5) + 21 = 49(0.5)
3.5 + 21 = 24.5
24.5 = 24.5
The equation is true so r = 0.5

The formula for the volume of a cylinder is V = xrh. The cylinder to the right has an exact volume of 720x cubic
meters. Find its height.
.6 m
The height of the cylinder is
(Simplify your answer.)
Answer:
You have the formula wrong.
The volume of a cylinder = PI * radius^2 * height
To find the height, the formula is:
height = volume / (PI*radius^2)
I'm assuming the radius = .6 meters so
height = 720 / (3.14159265 * .6^2)
height = 720 / 1.130973354
height = 636.61977 meters
