Answer:

38.1 cm²

Step-by-step explanation:

area of full circle = π6² = 113.04 cm²

area of 150° segment = (150/360)(113.04) = 47.1 cm²

triangle base = sin 75° x 6 x 2 = 11.59

triangle height = cos 75° x 6 = 1.553

area of triangle = 1/2(11.59)(1.553) = 9 cm²

150° segment - triangle = 47.1 - 9 = 38.1 cm²

Mrs. Leary wants to buy some plants and potting soil. Each plant costs $2.50 and each bag of potting soil costs $3.25. Mrs. Leary wants to spend no more than $50. If Mrs. Leary buys 4 bags of potting soil, which inequality represents the number of plants, p, that she may buy?

Answers

Answer: Ok while i was working out this problem I started by multiplying so i started by 5

2.50 x 5 = 12.5

3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.

2.50 x 7 = 17.5

3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..

2.50 x 9 = 22.5

3.25 x 9 = 29.25 and that equaled 51.75

so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.

A) I only
B) II only
C) III only
D) I and II only

Answers

Answer:

Think of the equation as an equation for a line  y = m x + b  where in this case  C = 5 9 ( F − 32 )  or  C = 5 9 F − 5 9 ( 32 )  You can see the slope of the graph is  5 9 , which means that for an increase of 1 degree Fahrenheit, the increase is  5 9  of 1 degree Celsius.  C = 5 9 ( F )  C = 5 9 ( 1 ) = 5 9  Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of  9 5  degrees Fahrenheit.  C = 5 9 ( F )  1 = 5 9 ( F )  ( F ) = 9 5  Since  9 5  = 1.8, statement II is true.  The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of  5 9  degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:  C = 5 9 ( F )  C = 5 9 ( 5 9 )  C = 25 81 ( which is ≠ 1 )  An increase of  5 9  degree Fahrenheit leads to an increase of  25 81 , not 1 degree, Celsius, and so Statement III is not true.  The final answer is D.

Which table shows exponential decay

From the figure of exponential decay :

When the value of one variable of the function is decreased with increase in the number of other variable, then it is called the exponential decay function with constant exponential coefficient.

It can be given as,

[tex]\frac{dN}{dt}=-\lambda N[/tex]

Here, [tex]\lambda[/tex] is the exponential coefficient.

From Option A:

x      y

1      16

2      8

3      4

4      2

The exponential coefficient for first and second row is,

[tex]\lambda=\frac{16}{8}=2[/tex]

Similarly,

[tex]\lambda=\frac{8}{4}=2\\\\\lambda=\frac{4}{2}=2[/tex]

Hence, as all the values of exponential coefficient is same, thus this shown the exponential decay.

From option B:

The exponential coefficient for first and second row is,

[tex]\lambda=\frac{16}{12}=\frac{4}{3}[/tex]

Similarly,

[tex]\lambda=\frac{12}{8}=\frac{3}{2} \\\\\lambda=\frac{8}{4}=2[/tex]

THIS IS THE WORK OF ANOTHER BRAINLY USER NOT MINE

In this question, we are to get the total number of hours that Irina used in watching the movie which does not include the term used for airing the commercials.

Now to calculate this, let us first take a look at the shaded segmented bar. We can see that out of the 6 horizontal bars, 5 were shaded. What this means is that 5/6 of the hours went into airing the movie while 1/6 of the hour went into airing commercials

Now, mathematically the number of hours she viewed the movie without the commercials can be calculated by adding all these 5/6 hour in the 3 hours

Mathematically that would be 5/6 + 5/6 + 5/6 = 3 (5/6) or simply 3 * 5/6 = 5/2 = 15/6 hours
