there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?
Answer:6 students remaining
Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.

Gabriella goes for a power walk every three days, and Mona walks every fivedays. They both walked on Monday this week.a.After how many days will they both walk again on the same day?[3 pts]b.What day of the week will it be when they walk again on the same day?
Power Walking has been at the top of a natural range to walk with such a speed. A walk defines as a walking journey, and the further discussion can be defined as follows:
Given:
Power walking by the Gabriella by every 3 days
Walking by the Mona by every 5 days
Both walk on Monday then They both walked together,
after taking LCM of 5 and 3 that is = 15 days
For question a:
When both walk again after the same day is = 15 days
For question b:
"Tuesday" is the weekday that will it be when they walk again on the same day.

Find the lest number which is exactly divisible by 36 & 90 Maths
Answer:
180Step-by-step explanation:
You need to find the HCF of 36 and 90.
Prime factors of each:
36 = 2*2*3*390 = 2*3*3*5HCF includes all prime factors of both numbers:
HCF(36, 90) = 2*2*3*3*5 = 180To find the least number,
Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.
→ 36 = 2 × 2 × 3 × 3
→ 90 = 2 × 3 × 3 × 5
Then the required HCF will be,
→ 2 × 2 × 3 × 3 × 5
→ 180 (HCF)
Thus, 180 is the least number which is exactly divisible by 36 and 90.

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.

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

The domain is the set of all the x-values/inputs used by the function.
The range is the set of all y-values/outputs used by the function.
For #1:
The domain is { 1, 0, -1, 4 } because those are the x-values.
The range is { 3, 5, 7, -6 } because those are the x-values.

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
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.
