Answer: Rico is right.

(-1)(3x + 5)²

Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.

It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.

Then factor 9x² + 30x + 25 as

(3x + 5)²

Answer:

Number of adult tickets sold = 1170

Number of children tickets sold = 85

Step-by-step explanation:

Let,

x be the number of adult tickets sold

y be the number of child tickets sold

According to given statement;

x+y = 1255      Eqn 1

10x+7y=12295    Eqn 2

Multiplying Eqn 1 by 10

10(x+y=1255)

10x+10y=12550      Eqn 3

Subtracting Eqn 2 from Eqn 3

(10x+10y)-(10x+7y) = 12550 - 12295

10x+10y-10x-7y= 255

3y = 255

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{255}{3}\\y=85[/tex]

Putting y=85 in Eqn 1

x+85 = 1255

x = 1255-85

x = 1170

Hence,

Number of adult tickets sold = 1170

Number of children tickets sold = 85

Answer:

6 cm

Step-by-step explanation:

Given that:

A line that contains the points R, S and T.

Distance between R and S = [tex]2x[/tex]

Distance between S and T = [tex]3x[/tex]

To find:

The distance between S and T = ?

Solution:

The given situation and dimensions can be represented in the form of a diagram as shown in the attached diagram.

As per given statement and in the diagram, we can deduce that the sum of distance between R and S, S and T is equal to distance between R and T.

i.e. RS + ST = RT

[tex]2x + 3x = 10\\\Rightarrow 5x=10\\\Rightarrow x = 2[/tex]

ST = 3[tex]x[/tex] = 3 [tex]\times[/tex] 2 = 6 cm

Therefore, the answer is:

Distance between S and T is 6 cm.

If the space between R and S is 2x, the space between S and T is 3x, and RT is 10 centimeters long, then ST is 6 centimeters

Point S lies between points R and T on Line segment RT

RT   =  RS   +  ST

The space between R and S is 2x

That is, RS  =  2x

The space between S and T is 3x

That is, ST  =  3x

RT is 10 centimeters long

RT  =  10cm

Substitute RT = 10, ST = 3x and RS = 2x into the equation RT = RS + ST

10  =  2x  +  3x

10   =  5x

x  =  10/5

x   =  2

If x = 2, then

ST  =  3x

ST = 3(2)

ST =  6 centimeters

Answer:

6 * (x - 1.50) = 52.50 ; 10.25

Step-by-step explanation:

Given that :

Number of tickets purchased = 6

Coupon off per ticket = 1.50

Total Amount paid for tickets = $52.50

Let x = initial price of ticket :

Number of tickets purchased * (Initial ticket price - coupon) = total amount paid

6 * (x - 1.50) = 52.50

6x - 9 = 52.50

6x = 52.50 + 9

6x = 61.50

x = 61.50 / 6

x = 10.25

Hence, initial price of ticket = $10.25

Solving

[tex]\frac{x}{-6}[/tex] ≥ 12

Multiply both sides by - 6 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.

x ≤ - 72

Since x can equal 72 then there is a closed circle at x = - 72

Since x is less than 72 then the line points to the left.

Answer:The percent decrease was 15%

Step-by-step explanation:

In order to find this, use the percent change equation.  

(New - Old)/(Old) * 100 = % Change

Now input 149.42 for the New price and 175.80 for the Old price.  

(149.42 - 175.80)/(175.80) * 100 = % Change

-26.38/175.80 * 100 = % Change

-.15 * 100 = % Change

-15 = % Change

Step-by-step explanation:

1 foot = 12 inches.

Convert the dimensions of the region to inches:

2 feet = 24 inches

5 feet = 60 inches

Area of region = 24 x 60 = 1,440 sq. In.

Area of tile = 3 x 4 = 12 sq. In.

Number of tiles needed = 1440/12 = 120

120 tiles are needed.

Answer:

12√2, 12√2

Step-by-step explanation:

For x:

We have the hypotenuse and are trying to find the angle opposite to 45 degrees. Using sine = opposite / hypotenuse we get sin45=x/24 so x = 24sin45 = 24 * √2/2 = 12√2

Beacuse the angle is 45 degrees we know that the the missing angle is also 45 degrees (180 - 90 - 45 = 45) so x and y must be the same (the triangle is isosceles) so y is also 12√2

Answer:

The missing value is 6!

Step-by-Step Explanation:

First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)

Now, we can write this as a function, where we can represent the missing value as 'x'.

[tex]4+5+13+x=28[/tex]

In order to get the missing value, we must solve the equation.

Step 1: Simplify.

[tex]4+5+13+x=28\\22+x=28[/tex]

Step 2: Subtract 22 from both sides.

[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]

x is equal to 6, which means the missing volume of gas is 6!

Answer:

[tex]Scale = \frac{2}{3}[/tex]

Step-by-step explanation:

To solve this question, I'll use the coordinates of SV and S'V' as points of reference.

From the attachment:

[tex]S = (3,6)[/tex]

[tex]V = (15,3)[/tex]

[tex]S' = (2,4)[/tex]

[tex]V' = (10,2)[/tex]

First, calculate distance SV

Distance formula is:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

For SV:

[tex]d_1 = \sqrt{(15 - 3)^2 + (3 - 6)^2}[/tex]

[tex]d_1 = \sqrt{(12)^2 + (-3)^2}[/tex]

[tex]d_1 = \sqrt{144 + 9}[/tex]

[tex]d_1 = \sqrt{153}[/tex]

For S'V'

[tex]d_2 = \sqrt{(10 - 2)^2 + (2 - 4)^2}[/tex]

[tex]d_2 = \sqrt{64 + 4}[/tex]

[tex]d_2 = \sqrt{68}[/tex]

The scale factor is then calculated using:

[tex]Scale = \frac{S'V'}{SV}[/tex]

[tex]Scale = \frac{d_2}{d_1}[/tex]

Substitute values of d1 and d2

[tex]Scale = \frac{\sqrt{68}}{\sqrt{153}}[/tex]

[tex]Scale = \sqrt{\frac{68}{153}}[/tex]

[tex]Scale = \sqrt{\frac{1}{2.25}}[/tex]

[tex]Scale = \frac{1}{1.5}[/tex]

Express as a proper fraction

[tex]Scale = \frac{1*2}{1.5*2}[/tex]

[tex]Scale = \frac{2}{3}[/tex]

The centimeter equivalent of Sadie's height is  142.875 cm.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Sadie is 63.5 inches tall and 2.54 cm equals 1 inch.

∴ Sadie's height in cm will be his height in inches multiplied by 1 inch equivalent of cm which is,

= (63.5×2.25) cm.
