Answer:

Divide the length from the area to determine the possible width.

Step-by-step explanation:

The area of a rectangle is found by multiplying height and width.

Since the possible heights are given, you have to divide those from 350 to get their respective width.

Step-by-step explanation:

Answer:

y will be 8??

Step-by-step explanation:

y = 8 x= 16

Answer:

I am going to assume that "y" varies directly as "x."

y = kx

4 = k(2)

2 = k

y = kx

y = 2(16)

y = 32

Answer:

Step-by-step explanation:

Recall :

Probability of event A :

P(A) = number of required outcome / Total possible outcomes

Required outcome = odd number greater than 60

Odd numbers = numbers bit divisible by 2

Odd number > 60 : {61, 63,65,67, 69,71,73,75,77,79,81,83,85,87,89,91,93,95,97,99}

sorry I dont understand thsi I am very very sorry

Answer:

Given - A rectangle whose area is 1 2/5 m^2

- length is 4/5 m

To find - Length of rectangle

Solution -

1 2/5 = 7/5 m^2

Let the length be X

Area of rectangle= Length × Breadth

7/5 = X × 4/5

7/5 × 5/4 = X

7/4 = X

Length of rectangle= 7/4

Answer: $7.31

Step-by-step explanation:

30j+40% + 25j= 562.8

30j+25j= 55j

55j + 40% = 562.8

40% of 55 is 22

77j = 562.8

562.8 77 = 7.309090909.....

Simplify 7.309090909

$7.31 Per hour.

Step-by-step explanation:

Function

The circulatory system transports

blood and other materials.

lungs and blood vessels

Function

The respiratory system is where gas exchange occurs.

heart, arteries, veins, and capillaries

Circulatory system works with the respiratory system to make sure that oxygen-rich blood can flow through the body.

Respiratory system supports your circulatory system with air, or more specially oxygen, which is sent to other organs from the arteries.

Answer:

83

Step-by-step explanation:

First do 2(6 x 4) = 48

Next do 2(2.5 x 4) = 20

Then do 6 x 2.5 = 15

Finally add the three numbers: 48 + 20 + 15 which equals 83

Answer:

2/3 or 0.6

Step-by-step explanation:

Convert 1 2/3 to an improper fraction: 5/2. Cancel the common factor of 5 to get 2*1/3, then combine 2 and 1/3 for 2/3. 2/3 is your answer. 0.6 is the decimal form for this answer.

x(x-19) =-81

Answer:

THE SMALLEST FORMS:

- smallest prism ---> the cube with all sides 2 ==> the volume is 2*2*2 = 8 cm^3

- smallest pyramid number one ---> the pyramid with base sides 2 and the height also 2 ==> the volume is (1/3)*2*2*2 = 8/3 cm^3

- smallest pyramid number two ---> the pyramid with base sides 2 and the lateral sides also 2 ==> the radius of the base is sqrt(2) ==> [pyramid_height]^2 = [lateral_side]^2 - [base_radius]^2 = 2^2 - sqrt(2)^2 = 4 - 2 = 2 ==> pyramid_height = sqrt(2) ==> the volume is (1/3)*2*2*sqrt(2) = 4*sqrt(2)/3 cm^3

- smallest cylinder --> the cylinder of diameter 2 and height also 2 ==> the radius is diameter/2 = 2/2 = 1 ==> the volume is pi*(radius^2)*height = pi*(1^2)*2 = pi*1*2 = 2*pi cm^3

The lesser volume is the volume of the smallest pyramid number two. ==> it's wax cost is approximately 0.0075 * 4 * 1.42 / 3 $ per candle = 0.014 $ per candle ==> the total cost  per candle is approximately 0.014 + 1.6 = 1.614 $ per candle.

THE BIGGEST FORMS:

- biggest prism ---> the cube with all sides 10 ==> the volume is 10*10*10 = 1000 cm^3

- biggest pyramid number one ---> the pyramid with base sides 10 and the height also 10 ==> the volume is (1/3)*10*10*10 = 1000/3 cm^3

- biggest pyramid number two ---> the pyramid with base sides 10 and the lateral sides also 10 ==> the radius of the base is 5*sqrt(2) ==> [pyramid_height]^2 = [lateral_side]^2 - [base_radius]^2 = 10^2 - [5*sqrt(2)]^2 = 100 - 50 = 50 ==> pyramid_height = 5*sqrt(2) ==> the volume is (1/3)*10*10*5*sqrt(2) = 500*sqrt(2)/3 cm^3

- biggest cylinder --> the cylinder of diameter 10 and height also 10 ==> the radius is diameter/2 = 10/2 = 5 ==> the volume is pi*(radius^2)*height = pi*(5^2)*10 = pi*25*10 = 250*pi cm^3

The bigger volume is the volume of the biggest prism (the side-10 cube). ==> it's wax cost is  0.0075 * 1000 $ per candle = 7.5 $ per candle ==> the total cost per candle is 7.5 + 1.6 = 9.1 $ per candle

The range of the cost is the interval [1.614 ; 9.1]. Depending on other prices on the market,  you greed, and other factors you will put a profit margin: maybe 20% of the cost ; maybe a fixed margin like 5$. So the price per candle will be the cost per candle plus the profit margin per candle.

If I were to choose the base length I would have to say 6 because it is the arithmetic mean between 2 and 10: (2+10)/2 = 12/2 = 6. 2cm is too small, and 10cm is too big.

Also if you start with a rectangle of length 10 and width 2 and you have to find the rectangle with the largest area by being allowed to increase the width and decrease the width with the same quantity you get this:

Area of the new rectangle is (10-x)(2+x) = -x^2 + 8x + 20 = -x^2 + 8x -16 + 36 = -(x^2 - 2*x*4 + 4^2) + 36 = -(x-4)^2 + 36 = 36 - (x-4)^2 which has the maximum value of 36 because out of 36 you subtract a positive value. You get the maximum when (x-4)^2 = 0 ==> x-4=0 ==> x=4

The new length is 10-4=6 and the new width is 2+4=6.

Next I would choose the height of the prism (I like prisms :P) to be [the_golden_ratio]*[base_side] which is approximately 1.618 * 6 = 9.708 which I would round up to 10. ==> The volume would be 6*6*10 = 360 cm^3. ==> the cost would be 0.0075*360 + 1.6 = 2.7 + 1.6 = 4.3 $ per candle. And because my candle is so perfect I'd put the profit margin to be 5.69 $ per candle so I can proudly show it in the store with the price of 4.3 + 5.69 = 9.99 $ :)
