Answer:

27 hours

Step-by-step explanation:

We are given the information that it takes 6 hours for 20 workers to seed 40 acres. This means that with 20 workers the rate is 40 acres in 6 hours, or 40/6 = 6.67 acres per hour. When we only have 10 workers, we only have half as many people, therefore the rate will be twice as slow, so with 10 workers, the rate is 6.67/2 = 3.34 acres/hour.

To find how long it takes to seed 90 acres we just need to divide 90 by the rate. 90/3.34 = 27 hours.

Answer:

Volume: 203,594

Surface Area: 105,237

----------------------------------------------------------------------------------------------------------

Let's start with surface area because it is a bit complex.

[tex]A = 5 ah + \frac{1}{2} \sqrt{5(5 + 2 \sqrt{5})}~a^2[/tex]

Now, we must break all of these factors into an equation.

remember, the height is 4, the base is 172

[tex]A = 5 * 172 * 4 + \frac{1}{2} * \sqrt{5 * (5 + 2 * \sqrt{5})} * 172^2[/tex]

[tex]A = \sf 1.05237 * 10^5 = 105,237[/tex]

So that should wrap things up for surface area, being 105,237

________________________________________________________

Now, we move on to the volume of this pentagonal prism.

[tex]A = \frac{1}{4} \sqrt{5(5 + 2 \sqrt{5})}~a^2h[/tex]

Similar to surface area, but different.

[tex]A = \frac{1}{4} * \sqrt{5 * (5 + 2 * \sqrt{5})} * 172^2 * 4[/tex]

And the result of this is...

[tex]A = \sf 2.03594 * 10^5[/tex]

Which is also equal to ⇒ 203,594

please let me know if this helped or was correct, I really spent a lot of time on this and would like to hear any good or bad feedback. Thanks!

Answer:

c)  124.96

Step-by-step explanation:

Geometric series:  100 + 20 + ... + 0.16

First we need to find which term 0.16 is.

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

(where a is the first term and r is the common ratio)

To find the common ratio r, divide one term by the previous term:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{20}{100}=0.2[/tex]

Therefore, [tex]a_n=100(0.2)^{n-1}[/tex]

Substitute [tex]a_n=0.16[/tex] into the equation and solve for n:

[tex]\implies 100(0.2)^{n-1}=0.16[/tex]

[tex]\implies (0.2)^{n-1}=0.0016[/tex]

[tex]\implies \ln(0.2)^{n-1}=\ln0.0016[/tex]

[tex]\implies (n-1)\ln(0.2)=\ln0.0016[/tex]

[tex]\implies n-1=\dfrac{\ln0.0016}{\ln(0.2)}[/tex]

[tex]\implies n=\dfrac{\ln0.0016}{\ln(0.2)}+1[/tex]

[tex]\implies n=5[/tex]

Therefore, we need to find the sum of the first 5 terms.

Sum of the first n terms of a geometric series:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Therefore, sum of the first 5 terms:

[tex]\implies S_5=\dfrac{100(1-0.2^5)}{1-0.2}[/tex]

[tex]\implies S_5=124.96[/tex]

Answer:

A: Yes, the sum of two sides are greater than the third side.

B: Yes, the sum of two sides are greater than the third side. (Would be an equiilateral triangl.)

C: No, the sum of two sides are less than the third side.

In general, To determine if 3 side lengths are a triangle, use the triangle inequality theorem, which states that the sum of 2 sides of a triangle must be greater than the third side. Therefore, all you have to do is add together each combination of 2 sides to see if it's greater than the third side.

The first trigonometric expression cot x and sin x in terms of the second expression is one over tan x and one over cosec x.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

Write the first trigonometric expression in terms of the second expression.

The cotangent can be written as

[tex]\cot x= \dfrac{1}{\tan x}[/tex]

And the sine can be written as

[tex]\sin x = \dfrac{1}{\csc x}[/tex]

Answer:

f(x) ≈ −2.42x3 + 15.89x2 − 7.55x + 12

Step-by-step explanation:

Notice that the year data are evenly spaced. Check the first differences between the total number or units to see if the data set is linear.

First Differences

41 − 18 = 23

67 − 41 = 26

82 − 67 = 15

69 − 82 = −13

17 − 69 = −52

Because the first differences are not constant, a linear model is not the best model of the data. Check the second differences to see if the data set can be modeled by a quadratic function.

Second Differences

26 − 23 = 3

15 − 26 = −11

−13 − 15 = −28

−52 − (−13) = −39

Because the second differences of the independent variable are not constant, a quadratic model is not the best model of the data. Check the third differences to see if the data set can be modeled by a cubic function.

Third Differences

−11 − 3 = −14

−28 − (−11) = −17

−39 − (−28) = −11

The third differences are approximately the same so we will use a cubic function to represent the data.

Enter the data into a calculator. Plot the data and find the cubic regression equation that best models the data.

The value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

Percentage increase is the amount added to the initial value in the percentage part.

The value of a plot of land which is increases 8% every year has the current value of $350000.

The final value owner wants is $570000.  Shanna writes an exponential function of the form, to model the value,v, of the land in t years as,

[tex]v(t)=a\times b^t[/tex]

Here, in this exponential function the value of a is fixed or initial term which is $350000 and the value of b is the constant term which is change factor. Here, the value of b is 8%.

b=8%

b=8/100

b=0.08

Thus, the value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

Answer:

Step-by-step explanation:

Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time[1]. Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years[2].

Ice coring has been around since the 1950s. Ice cores have been drilled in ice sheets worldwide, but notably in Greenland[3] and Antarctica[4, 5]. High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6].

Answer: If replaced: 0.075 or 7.5%

If not replaced: 0.00455 or 0.455%

Step-by-step explanation:

If the diamonds are replaced after each draw:

The probability of drawing a real diamond is 9/12, found by making the numerator the number of real diamonds and adding the total number of diamonds to find the denominator. 3+9 = 12.

9/12 can be reduced to 3/4 by dividing the numerator and denominator by 3.

To find the probability of all 9 diamonds drawn being real, multiply 3/4 by itself 9 times. [tex]3^9[/tex] = 19683. [tex]4^9[/tex] = 262144. This creates a probability of 19683/262144. This cannot be reduced because there is no common factor. To express as a decimal, divide. 19683/262144 = 0.07508. To turn this into a percent, multiply by 100. 0.07508*100 = 7.508

If the diamonds are not replaced after each draw:

Start with the probability of drawing a single diamond: 9/12. After each draw, both the numerator and denominator have 1 subtracted from them, since there is 1 less real diamond and 1 less diamond in total. This will give you the equation (9/12)*(8/11)*(7/10)*(6/9)*(5/8)*(4/7)*(3/6)*(2/5)*(1/4). This equals 0.00455. To find as a percent, multiply by 100. 0.00455*100 = 0.455

Answer:

x = 15,  45 degree angle

Step-by-step explanation:

2x + 15 and 6x - 45 adds up to 90 degrees

(2x + 15) + (6x - 45) = 90

combine like terms:

2x + 6x = 8x

15 + (-45) = -30

8x - 30 = 90

8x - 30 + 30 = 90 + 30

8x = 120

8x / 8 = 120 / 8

x = 15

2(15) + 15

30 + 15 = 45 degree angle

6(15) - 45

90 - 45 = 45

Answer:

x = 15.

Step-by-step explanation:

The figure is a square so opposite sides are congruent and parallel.

The 2 angles marked are interior alternate angles, so they are congruent.

Therefore:

2x + 15 = 6x - 45

15 + 45 = 6x - 2x

4x = 60

x = 15.
