Answer:

10x3=30

Step-by-step explanation:

X=2 is 10 and x=5 is 30.

10 is the factor of 30, and 10 could be multiplied by 3 to get 30.

OR 30 could be divided by 10, and you‘ll get 3.

Hope this helped! :)

A farmer is going to divide her 30 acre farm between two crops. Seed for crop A costs $30 per acre. Seed for crop B costs $15 per acre. The farmer can spend at most $600 on seed.
If crop B brings in a profit of $90 per acre and crop A brings in a profit of $160 per acre, how many acres of each crop should the farmer plant to maximize her profit?

Answers

Answer:

Rearrange Inequalities

0<= A <=40

0<= B <= 40

A <= -B + 40

A <= -2B + 50

Acres:: A + B <= 40

Seed:: 10A + 20B <= 500

Profit function:: P = 110A + 40B

Step-by-step explanation:

Answer:

the farmer should plant 40 acres of crop B.

Step-by-step explanation:

The restriction equations are:

x + y = 40 acres (1) (for areas; x = the area for crop A; y = the area for crop B).

10x + 20y = 700 (2) for the seed cost

or

x + 2y = 70

We have the following system of equations:

x + y = 40  

x + 2y = 70  

The additional obvious restrictions are x >= 0 and y >= 0.

The objective function is the profit:

F(x, y) = 60x + 70y

According to the conception/ideology of the linear programming method, we need to evaluate the  

objective function F(x, y) = 60x + 70y in three points (corner points):

(0, 40), (35, 0) and (10, 30)

We need to find the point where the objective function is maximal:

F(0, 40) = 60*0 + 70*40 = $2,800

F(35, 0) = 60*35 + 70*0 = $2,100

F(10, 30) = 60*10 + 70*30 = $2,700

Follows, the farmer should plant 40 acres of crop B.

If the area of a rectangular garden is 12x2−20x. What is the length if the width is 4x? 8x2−168 x squared minus 16 3x2−5x3 x squared minus 5 x 8x−168 x minus 16 3x−5

Answers

Answer:

3x - 5

Step-by-step explanation:

If the area of a rectangular garden is 12x²−20x. What is the length if the width is 4x?

The formula for the Area of a rectangular shape = Length × Width

Area = 12x² - 20x

Length = 4x

Width = Area/Length

Width = 12x² - 20x/4x

Width = 12x²/4x - 20x/4x

Width = 3x - 5

The width of the Rectangular shape = 3x - 5

PLEASE HELP PLEASE!!!!

Answers

21cm cause a^2 + b^2 = c^2

What is the diagonal of the square?

A square can have two diagonals. Each of the diagonal can be formed by joining the diagonally opposite vertices of a square.

A square has a side length of 15 cm.

The following is closest to the length of a diagonal of the square is;

[tex]\rm d^2 =15^+15^2\\\\d^2=225+225\\\\d^2=450\\\\d=21[/tex]

Hence, the length of a diagonal of the square is 21cm.

The baker's at a bakery can make 160 bagels in 4 hours how many bagesl can they bake in 16 hours? What is that rate per hour. "Explanation"

Answers

Answer:

640 bagels

Rate: 40bagels/hour

Step-by-step explanation:

If the baker's at a bakery can make 160 bagels in 4 hours, then;

160 bagels = 4 hours

To calculate the amount the baker can bake in 16hours, we can write;

x bagels = 16hours

Divide both expressions

160/x = 4/16

160/x = 1/4

Cross multiply

x* 1= 160 * 4

x = 640

Hence the baker can bake 640 bagels in 16hours

To know the rate per hour, we can write;

x bagel = 1hr

Recall that; 160bagels = 4 hours

Cross multiply

x * 4 = 1 * 160

4x = 160

x = 160/4

x = 40

Hence the rate per hour is 40bagels/hour

A car is traveling at a steady speed. It travels 1 1/2 miles in 2 1/4 minutes. How far will it travel in 46 minuets? In 1 hour?

Answers

Answer:

30.667, in 1 hour = 40 miles

Step-by-step explanation:

Set up a proportion so 1.5 miles / 2.25 minutes.

So 1.5/2.25 = x/46

solve for x 1.5(46)/2.25 = x so x = 30.667

In one hour is 60 minutes so  1.5(60)/2.25 = x

Answers

Answer:

the answer is 5

Step-by-step explanation:

it is right jk

Answer:

Step-by-step explanation:

We know area of a rectangle is xy where x and y are its dimensions.

A=xy

If we factor the area we will get the dimensions.

A=15k^4+35k^3+20k^2

(this can be factored in many ways to produce the same area, the answer choices you are given can be any given combination of factors.)

A=15k^4+15k^3+20k^3+20k^2

A=15k^3(k+1)+20k^2(k+1)

A=(15k^3+20k^2)(k+1) (this is one way)

A=5k(3k^2+4k)(k+1)

A=(3k^2+4k)(5k^2+5k) (and another way)

Either expression would give you width and length (or length and width) as they all produce the area of the original equation.

[tex]RS = 2.2ft[/tex]

[tex]QR = 4.5ft[/tex]

See attachment for ΔQRS

To calculate <Q, we make use of:

Where

[tex]Opposite = RS[/tex]

[tex]Hypotenuse = QR[/tex]

[tex]sin\ Q = \frac{RS}{QR}[/tex]

[tex]sin\ Q = \frac{2.2}{4.5}[/tex]

What is the area of triangle ABC

Answers

Answer:

A = 24 cm²

Step-by-step explanation:

The area (A) of Δ ABC is calculated as

A = [tex]\frac{1}{2}[/tex] × AB × AC

Calculate AC using Pythagoras' identity

AC² + AB² = BC²

AC² + 6² = 10²

AC² + 36 = 100 ( subtract 36 from both sides )

AC² = 64 ( take the square root of both sides )

AC = [tex]\sqrt{64}[/tex] = 8

Then

A = 0.5 × 6 × 8 = 24 cm²

perimeter of a rectangle  = twice the length  plus  twice the width

P = 2L + 2W    equation 1      P = 86 ft

Given the length is seven feet more than the width

L = W + 7         equation 2

Substitute equation 2 into equation 1

P = 2(W+7) + 2W    =  86 ft

     2W +14 + 2W    =  86 ft
