Answer:

neither

Step-by-step explanation: simply no way to get

Divide the hexagon into 6 equal streak triangles which would have side length equal to the radius of the circle.

the area of an equal lateral triangle = sqrt(3)/4 x radius^2

the area of the hexagon would be 6 x sqrt(3)/4 x radius^2

Area = 6 x sqrt(3)/4 x 8^2 = 166.2768 square feet

rounded to the nearest whole foot = 166 square feet.

Answer:

28.72

Step-by-step explanation:

The area for the 8 inch diameter cake is 50.27

1/4·π·8^2

but the area for the 10 inch diameter cake is 78.54

1/4·π·10^2 = 78.54

All you do to find the difference is

78.54 - 50.27 which is 28.72

Answer:

r = 10 , h = 4

r = 2 h = 100

Step-by-step explanation:

V =  [tex]\pi r^{2}[/tex]h

V = [tex]10^{2} \pi[/tex] (4)

V = 100[tex]\pi[/tex](4)

V = 400[tex]\pi[/tex]

Using it's concept, it is found that there is a 75% probability that the next customer will pay with cash.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, out of 87 + 5 + 24 = 116 customers, 87 paid with case, hence the probability as a decimal is given by:

p = 87/116 = 0.75.

As a percentage, we have that:

0.75 x 100% = 75%.

75% probability that the next customer will pay with cash.

Answer:

80$ (maybe 85)

Step-by-step explanation:

combined rate =20$/hour

It can take 85 minutes for you and your friend to mow 2 acres. 35+50=85. So 85*3 (because 6/2=3) is the number of minutes you work. 255 minutes. So 4.25 hours. If you are only being paid for hours, then you will make $80. If you are being paid the extra minutes the $85. I believe that the answer you should pick is $80.

Answer:

$41.18

Step-by-step explanation:

35/50 = 0.7

Therefore, in the time it takes you mow 1 acre, your friend mows 0.7 acres

Therefore, for every 35 minutes = 1 + 0.7 = 1.7 acres are mowed by you and your friend combined.

⇒ 1.7 ÷ 35 = 0.04857142... acres mowed every minute

⇒ 6 ÷ 0.04857142...  = 123.5294118... minutes to 6 acres

Therefore, it takes 35/17 hours for you and your friend to mow 6 acres

If your rate is $20 per hour, then 35/17 x 20 = $41.18

Answer:

  both are Quadratic

Step-by-step explanation:

To determine if a table of function values represents a linear function or a quadratic function, you can often look at first- and second-differences of the dependent variable.

The x-values are evenly spaced in each case, so the question can be answered by looking at differences in y-values. The set of first differences is the result of subtracting a given column from the next. The set of second differences is found by doing the same, using the first differences.

First differences; 21 -11 = 10, 35 -21 = 14, 53 -35 = 18, 75 -53 = 22

Second differences: 14 -10 = 4, 18 -14 = 4, 22 -18 = 4

The second differences all have the same value: 4. That means the function is 2nd degree, quadratic.

__

First differences: 10 -12 = -2, 9 -10 = -1, 9 -9 = 0, 10 -9 = 1

Second differences: -1 -(-2) = 1, 0 -(-1) = 1, 1 -0 = 1

The second differences all have the same value: 1. That means the function is 2nd degree, quadratic.

__

Additional comment

The level at which differences are the same tells you the degree of the polynomial that will match the given function points. If first differences are constant, then the function is 1st degree: linear. Here, second differences are constant, so the functions are 2nd degree: quadratic. If you have to go to 4th differences to get constant values, then the table will require a 4th-degree polynomial to match its values. This presumes the x-values are all evenly-spaced.

If the x-values are not evenly spaced, then determining the degree of the function can be done by graphing and/or using regression formulas. Various interpolation polynomials are available for matching the points exactly.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.

Answer:

A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3

Step-by-step explanation:

A. 4x= -28

Divide both sides by 4.

[tex]\frac{4x}{4\\}[/tex]=[tex]\frac{-28}{4}[/tex]. x= -7

B. x- -6= -2 ->  x+6= -2

Subtraction 6 to both sides.

x- +6-6= -2-6,  x= -8

C. -x+= -9 -> x= 9

D. -3x+7=1

Subtraction 7 to both sides.

-3x+7-7 =1-7 , -3x=-6

Divide both sides by -3.

[tex]\frac{-3x}{-3}[/tex] = [tex]\frac{-6}{-3}[/tex], x= 2

E. 25x+-11= -86 -> 25x-11= -86

Add 11 to both sides.

25x-11+11= -86+11, 25x= -75

Divide both sides by 25.

[tex]\frac{25x}{25}[/tex] = [tex]\frac{-75}{25}[/tex], x= -3

2. 2x+9= -15

Subtraction 9 to both sides.

2x+9-9= -15-9,  2x= -24

Divide both sides by 2.

Step-by-step explanation:

The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex].

After a careful reading of the statement, we find that final position ([tex]\vec r[/tex]) by the end of the second day is found by means of this vector sum:

[tex]\vec r = \vec r_{1} + \vec r_{2}[/tex] (1)

Where:

If we know that [tex]\vec r_{1} = (200\,km \cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})[/tex] and [tex]\vec r_{2} = (150\,km\cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex], then final position of Beatriz relative to origin is:

[tex]\vec r = (200\,km\cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})+(150\,km \cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex]

[tex]\vec r = (48.670, -314.159)\,[km][/tex]

And the direction relative to the starting point ([tex]\theta[/tex]), in degrees, is found by following inverse trigonometric relation:

[tex]\theta = \tan^{-1} \frac{r_{y}}{r_{x}}[/tex] (2)

If we know that [tex]r_{x} = 48.670\,km[/tex] and [tex]r_{y} = -314.159\,km[/tex], then the direction of Beatriz relative to the starting point of her trip is:

[tex]\theta = \tan^{-1} \left(\frac{-314.159\,km}{48.670\,km} \right)[/tex]

[tex]\theta \approx 278.806^{\circ}[/tex]

The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex]. [tex]\blacksquare[/tex]
