Explanation:

The volume of a cylinder is given by

Now, to correct the order of the cylinders from least to greatest, we have to calculate the volume of each.

(a). A cylinder with a diameter of 28 units and a height of 18 units.

Diameter is 2 times radius; therefore, r = 14 and the volume is

(b). A cylinder with a radius of 13 units and a height of 17 units.

The volume is

(c). A cylinder with a diameter of 30 units and a height of 14 units.

The radius is 15 units; therefore, the volume is

(d). A cylinder with a radius of 12 units and a height of 20 units.

The volume is

Hence, from least volume to greatest volume the order is

The linear equation that models the average price of a new home in terms of the year x is given by y = -5600x + 294000 and the average price of a new home would be $238000 in 2014.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The line must pass through points (0, 294000) and (7, 288400) which is given in the question.

We have to determine the slope of the line :

m = (y₂ - y₁)/(x₂ -x₁ )

m = (288400- 294000)/(7 -0)

m = -5600

This represents new home per year

So with your y-intercept of 294000, your equation becomes

y = -5600x + 294000

Using this equation to predict the average price of a new home in 2014.

Let y be the average price of a new home in the year x, where x = 0 represents the year 2004.

Substitute the value of  x = 10 for the year 2014

y = -5600(10) + 294000

y = -56000 + 294000

y = 238000

Hence, the average price of a new home would be $238000 in 2014.

Then, the perimeter of the circle is 22 cm.

Perimeter = 2πr = 22 cm.

Where, π = 3.14 and r is the radius of the circle.

2πr = 22 cm.

r = 11/π 11/3.14

The area of the circle is found as;

Area  = πr²

Put the values.

Area  = 3.14(11/3.14)²

Area = 38.53 cm².

For the square.

Perimeter = 4 side

22 = 4 side

side = 22/4 = 11/2 = 5.5

Let Lydia invest $x

Half of her stock pays 11% dividend.

So mathematically the amount will be

With the other half, she pays stocks in 14% interest

So mathematically

Her total annual interest is $420

So

She invested $3360 in total

And $1680 in each.

To solve this problem we can evaluate te terms in the table in each equation so:

For A) y = -x + 7

we replace (3,10)

So A is incorrect.

For B) y = x + 7

we replace (3,10), (4,11), (5,12) and (6,13)

So B is the correct answer

The standard deviation of the mass of the bluetits to 3 significant figures is 1.30.

Standard deviation is used to determine the variation of a dataset. Standard deviation is the spread of a data from the mean of the dataset. The higher the value of the standard deviation, the greater the spread of the dataset.

In order to determine the standard deviation, take the following steps:

Determine the mean of the mass : (9.9 + 9.8 + 12.2 + 13.3 + 11.8 + 10.2 + 12. 3 + 12.9 + 9.2 + 10.3 + 10.7 + 12.1) / 12 = 11.225

Determine the difference between each value and the mean and then square the result and then find the square root. The answer gotten is the standard deviation. 1.30

The cost of each bottle is $[tex]1[/tex]

Given:

To find: Cost of each bottle of juice?

It is given that Miguel bought snacks for his team's practice which includes a bag of popcorn, and [tex]20[/tex] packs of juice bottles out of which the bag of popcorn cost him $[tex]3.33[/tex] , and the total cost before tax of all the items costs him $[tex]23.33[/tex]

Now we have to find that how much each bottle of juice costs him as asked in the given question.

Let the bag of popcorn's amount be x and the pack of bottle juice is y

Now according to the linear equation in two variable

[tex]x*1+y*20=23.33[/tex]........(1)

where 1 is the total pack of popcorn bag and [tex]20[/tex] the amount of bottle juice packs

As we know that [tex]x=3.33[/tex] since a bag of popcorn costs him $[tex]3.33[/tex]

Now put the value of x in (1) hence,

[tex]3.33*1+y*20=23.33[/tex]

On further solving we get,

[tex]20y=20[/tex]

On further solving we get,

[tex]y=1[/tex] as the price of every juice of bottle.

Answers:  c = 17 and c = 18

==================================================

Explanation:

Let's expand out the left hand side and rearrange terms like shown in the steps below.

(ax + 3)(bx + 4) = 6x^2 + cx + 12

ax(bx + 4)+3(bx + 4) = 6x^2 + cx + 12

abx^2 + 4ax+3bx + 12 = 6x^2 + cx + 12

abx^2 + (4a+3b)x + 12 = 6x^2 + cx + 12

Then equate the corresponding coefficients

We'll use the fact that a+b = 5. Solving for 'a' gets us a = 5-b

Plug this into the equation dealing with the x^2 coefficients.

ab = 6

(5-b)b = 6

5b-b^2 = 6

0 = b^2-5b+6

b^2-5b+6 = 0

(b-3)(b-2) = 0

b-3 = 0 or b-2 = 0

b = 3 or b = 2

If b = 3, then a = 5-b = 5-3 = 2

If b = 2, then a = 5-b = 5-2 = 3

Therefore, the solutions to this system of equations

[tex]\begin{cases}a+b = 5\\ab = 6\end{cases}[/tex]

are (a,b) = (2,3) and (a,b) = (3,2)

In other words, the answer to the question "what two numbers multiply to 6 and add to 5?" is "2 and 3". The order doesn't matter which is why we can flip the 'a' and b values.

---------------------------------

Go back to 4a+3b = c which was us equating the x coefficients.

This is the same as c = 4a+3b

Plug in a = 2 and b = 3

c = 4a+3b

c = 4*2+3*3

c = 8 + 9

c = 17 is one possible value of c.

Now let's plug in a = 3 and b = 2

c = 4a+3b

c = 4*3+3*2

c = 12 + 6

c = 18 is the other possible value of c.
