Answer:

87

Step-by-step explanation:

Smaller number = 43

Bigger number= 44

Sum = 43+44

Question Answer: 44+43 = 87

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

You need to find the HCF of 36 and 90.

Prime factors of each:

HCF includes all prime factors of both numbers:

To 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.

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].

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.

I'll let you try #2.  if you write back with your answer, I'll reply to let you know if you did it correctly.

Answer:

Step-by-step explanation:

No, the results are not necessarily representative of the school as a whole.

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.

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
