If a right circular cone intersects a plane that runs parallel to the edge of the cone, the resulting curve will be a <u>parabola</u>.

A parabola is curved from one end and open from other end, therefore it would fit the best.

Hope I could help! :)

<h2>Answer:</h2>

If a right circular cone intersects a plane that runs parallel to the edge of the cone, the resulting curve will be a:  Parabola.

<h2>Step-by-step explanation:</h2>
  • If a plane is perpendicular to the axis of rotation of the cone then the resulting cross section will be a <em>Circle.</em>
  • If the plane is placed slightly tilted across the axis of rotation of the cone then the resulting cross section will be a<em>  Ellipse.</em>
  • If a plane is placed such that it is parallel to the side of the cone i.e. the edge of a cone then the resulting cross section is <em>Parabola.</em>

A farmer owns a 100 acre farm and plans to plant at most three crops. The seed for crops A,B, and C costs $40, $20, and $30 per
aev [14]

Answer:

The number of acre per crop for maximum profit is;

Crop A = 0 acres

Crop B = 60 acres

Crop C = 40 acres

Profit, P = $26,000

Step-by-step explanation:

We plant A in X acres

B in Y acres and

C in Z acres

Therefore, X + Y + Z ≤ 100

we work A for 1·X workdays

B for 2·Y workdays and

C for 1·Z workdays

Where X + 2·Y + Z ≤ 160

$40·X for crop A

$20·Y for crop B and

$30·Z for crop C is spent whereby

$40·X + $20·Y + $30·Z ≤ $3200

The farmer makes

$100·X from crop A

$300·Y from crop B and

$200·Z from crop C

P = $100·X + $300·Y + $200·Z

Therefore, we have three equations with three unknowns solving the equations simultaneously, we have

X + Y + Z = 100....................................................(1)

X + 2·Y + Z = 160.................................................(2)

$40·X + $20·Y + $30·Z = $3200....................(3)

By subtracting equation (1) from (2) gives Y = 60 acres

Multiplying equation (1) by 40 and subtracting from (3) we  have Z = -40

and therefore, Y = 80

If he plants only B the farmer has 2 work day per acre and since there is a max of 160 days, he can only plant on 80 acres, therefore, total profit = $300 × 80 = $24,000

Comparing the profit per acre to the seed cost we have Profit for seed A = $100 while cost = $40 per acre,

If we remove seed A we have

Y + Z = 100....................................................(4)

2·Y + Z = 160.................................................(5)

$40·X + $20·Y + $30·Z = $3200....................(3)

Solving equation (4) and (5), we have Y = 60 acres and Z = 40 acres

Therefore, the profit becomes

$300 × 60 + $200 × 40 = $26,000.

I need help urgently!! I’ll make you brainliest!!
guajiro [1.7K]

Answer:

SQUARE= 108 blocks

CIRCLE= 97.97

# OF BUNDLES= 2.05, 3

Step-by-step explanation:

square- find perimeter

  • 22.5 x 4= 90ft
  • 90ft/10inches
  • convert 90 ft to inches> 90 x 12= 1080/10= 108

circle-

  • find the circumference= c=2piR
  • 2x3.14x13=81.64
  • 81.64ft to in = 979.68/10
  • =97  rounded

number of bundles = 205/100 =2.05, so 3

how many even numbers less than 1000 can be formed from the given digits 0,2,3,5; if repetition is not allowed ?​
Lunna [17]

Answer: 2 numbers

Step-by-step explanation:

Since we are looking for even numbers, 0 and 2 must be the last number.

So if we have 0 at the end, there are 6 possibilities:

2350, 2530, 3250, 3520, 5230, 5320.  None of these are less than 1000.

But, if we have 2 at the end, then we have 6 possibilities again:

0352, 0532, 3052, 3502, 5032, 5302. Only two of these are less than 1000.

So the only possibilities are 0350 and 0530, and so there are 2 possibilities.

Reduce the fractions using the greatest common factor 7 over 12
Airida [17]

Answer:

7/12 cannot be reduced

Step-by-step explanation:

7 = 7

12 = 2 * 2 * 3

7 and 12 have no common factors other than 1, so the fraction 7/12 cannot be reduced. 7/12 is already written in lowest terms.
