Answer: c

Step-by-step explanation: there is already 1/4 of the pie and we know that 80 people have chosen 80, so the 3 left have to add up to 240.

Answer:

No.

Step-by-step explanation:

It is not possible to make a triangle that has the angles measuring 60 degrees, 30 degrees and 45 degrees because the angles of a triangle have to add up to 180 degrees. 30+45+60=135

Therefore, these angles would not measure up to 180 degrees. It is not possible to make a triangle that has these angles. These angles measure up to 135 degrees not 180 degrees.

Answer:

1) $52,000

2) $43,200

3) P = 325 × x + 180 × y

4) x + y ≤ 240

2·x + y ≤ 320

325 × x + 180 × y ≤ 52,000

5) Please find a similar graph created with MS Excel

6) Corn will have 80 acres

Soybean will have 160 acres

7) $54,800

Step-by-step explanation:

The acres of cropland at the Waterbrook Farm, A = 240 acres

The profit per acre in corn production, p₁ = $325

The profit per acre in soybean production, p₂ = $180

The hours of labor required by each acre of corn = 2 hours

The hours of labor required by each acre of soybeans = 1 hours

The number of acres planted with corn = x

The number of acres planted with soybeans = y

1) The farm's profit, 'P', if they planted only corn is P = p₁ × A

∴ P = $325/acre × 320 hours/(2 hours/acre) = $52,000

The farm's profit if they planted only corn, P = $52,000

2) The farm's profit, 'P', if they planted only corn is P = p₂ × A

The required labor for cultivating the 240 acres at 1 hour/acre = 240 hours of labor

Therefore, the labor is sufficient for the entire farmland, we get;

The profit, P = $180/acre × 240 acres  = $43,200

∴ The farm's profit if they planted only soybeans, P = $43,200

3) The equation for the Waterbrook Farm's profit, 'P' can be found, depending on the area of the farm used for the corn and the soybeans as follows;

P = 325 × x + 180 × y

4) The system of inequalities includes;

x + y ≤ 240

2·x + y ≤ 320

325 × x + 180 × y ≤ 52,000

5) Using DESMOS, we have;

The graph of the systems of inequalities is plotted and a graph similar to the attached graph created with MS Excel is found

6) The maximum profit point found using DESMOS is (80, 160)

Therefore, for maximum profit, 80 acres should be used for corn while 160 acres should be used for soybeans

7) The maximum profit of planting both corn and soybeans is found from the profit obtained from the land divided between corn and soybeans in order to yield maximum profit as follows;

P = 325 × 80 + 180 × 160 = 54,800

The maximum profit of planting both corn and soybeans, P = $54,800.

Answer:

0.22 square units

Step-by-step explanation:

Area of the left over fabric = Area of the square piece - Area of the circle

let the side length of the square piece be 1 unit

Area of the square piece = 1 * 1

Area of the square piece = 1 square units

Area of the circle = πd²/4

d is the diameter of the circle = 1 unit (equivalent to the side length of the square)

Area of the circle = π(1)²/4

Area of the circle = 3.14/4

Area of the circle = 0.785square units

Area of the left over fabric = 1- 0785

Area of the left over fabric = 0.215 square units

Hence the amount of fabric that would be leftover is 0.22 square units

Answer:

0.22 square units

co-terminal angle for -960... can you tell me?  :D  w/o looking at my answer below?

Your answer for co-terminal angle is   ______________ :)

960 - 360 = 600

600 - 360 = 240

this is telling us that going in a clock wise direction.. as the -960 is, that the co-terminal angle is 240, which seems about right.. looking at the graph. so now. let's take 240 away from 360 to find that co-terminal angle but going in the positive direction or the counter clock wise direction

360-240 = 120

and yes.. that does look like 120 °  going in the positive direction.  

now do you know the sec identity  to use sin and cos???

look at the below diagram

sin     sec

cos    csc

tan    cot

the trig function line up like that for a reason

sin     1/sin

cos    1/cos

sin/cos   cos/sin

I put them in their sin and cos identities.. see.. they all line up that way

sec = 1/sin

csc = 1/cos

tan = sin/cos

cot = cos/sin

now... find

sec(120) = 1/sin(120)

do you know how to find sin(120) ?????

put it back to it's co-terminal angle in the 1st quadrat... I hope you know how to do this.. i'll just speed along... assuming you do

sin(120) = sin(60)= √3/2

so sec(120) = 1 / √3/2  

so sec(120) = 2/ √3

10)

csc(315) = 1/cos(315)

find the co-terminal angle that you know in the 1st quadrant again...

so 315 = 45 in the 1st quadrant.. I just looked and can see that

so

csc(315) = 1/cos(315   =  1/cos(45)     and cos(45) = √2/2

so then  1 /  √2/2   =   2 / √2

csc(315) = 2 / √2

what i'm really wondering about.. is .. where is question 9)

Answer: the owner should gather more.

Step-by-step explanation:

So they can have more overall data to make sure they are correct.

The owner should gather more data.

"A proportion is an equation in which two ratios are set equal to each other."

Consider given situation,

The results on the first day: { yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes}

Total slips = 12

number of slips marked yes: n(Yes)

On day 1, n(Yes) = 8

So, the proportion of happy shoppers would be,

= 8/12

= 67.7%

This means, approximately 68% of the 12 selected slips were marked "Yes"

On a different day, the owner found that 25% of the 12 selected slips were marked "Yes"

This means the percentage of happy shoppers decreased.

From these two results we cannot determine where people are happy shoppers or not.

So, the owner should gather more data.

[tex]x^y*x^n=x^{n+y}\\6+b=12\\b=6[/tex]

Answer:

6

Step-by-step explanation:

We are given here a exponential equation and we need to find out the value of b in the equation. So the given equation is ,

⇒5⁶ × 5^b = 5¹²

⇒ 5^(6+b) = 5¹² [ using aⁿ × aⁿ' = a^(n + n') ]

On comparing the bases and powers we have ,

⇒ 6 + b = 12

⇒ b = 12 - 6

⇒ b = 6

Answer:

A Rs. 500 note, and four Rs. 100 notes.

Step-by-step explanation:

The cost of the two shoes = Rs.1,300 + Rs. 1,800

                                            = Rs. 3,100

He gave 4 notes of Rs. 1,000 = 4 x Rs. 1,000

                                                 = Rs. 4,000

Manoj's expected change = Rs. 4,000 - Rs. 3,100

                                           = Rs. 900

Since he was returned 5 notes in the denominations of Rs. 500 and Rs. 100, then;

Rs. 500 + Rs. 100 + Rs. 100 + Rs. 100 + Rs. 100 = Rs. 900

Therefore, Manaoj was returned a Rs. 500 note, and four Rs. 100 notes.
