Rectangle R was dilated to form rectangle R’.
Which is the scale factor of the dilation?

Using the knowledge of the total sum of the internal angles of a triangle, the value of x would be 25

Recall :

Hence,

(x + 15) + (3x - 35) + 4x = 180

x + 15 + 3x - 35 + 4x = 180

8x - 20 = 180

8x = 180 + 20

8x = 200

x = 200 / 8

x = 25°

Therefore, the value of x is 25

Step-by-step explanation:

Given data

cost of 12 bottle = $9

How many bottle can $3 buy.

Given that $9 can buy 12 bottles

therefore $3 would by x bottles

cross multiply we have

9x=12*3

9x=36

divide both sides be 9

x=36/9

x=4 bottles

The cost per bottle is

9/12= $3/4

= $0.75 per bottle

if one bottle cost $0.75

the 7 bottles will cost =0.75*7

=$5.25

Answer:

4

Step-by-step expl

Since 12 bottles cost $9 then by doing

12/3=X

X=4

answer: 16

step by step explanation:

The total number of marbles = 32 marbles.

We have ratio of the number of marbles in the red bag to the number in the blue bag is 3 : 5. After that, two marbles are moved from the blue bag to the red bag, making the ratio 7 : 9.

We have to find out how many marbles are there in total.

Yes, a:b equals to [tex]\frac{a}{b}[/tex] - where ' a ' is called Antecedent and ' b ' is called Consequent.

Let the total number of marbles be x.

Let the number of marbles in the red bag be ' x ' and in blue bag ' y '.

According to question -

[tex]\frac{x}{y} =\frac{3}{5}[/tex]

5x = 3y

x = [tex]\frac{3y}{5}[/tex]

After the two marbles are moved from blue bag are moved into the red bag, then -

[tex]\frac{x+2}{y-2} =\frac{7}{9}[/tex]

9(x + 2) = 7(y - 2)

9x + 18 = 7y - 14

9x - 7y = -32

9 ([tex]\frac{3y}{5}[/tex]) - 7y = -32

[tex]\frac{27y}{5} - 7y =-32[/tex]

[tex]\frac{-8y}{5}=-32[/tex]

-8y = -32 x 5

y = 4 x 5

y = 20

Therefore -

x = [tex]\frac{3\times20}{5}[/tex] = 12

Hence, the total number of marbles = x + y = 20 + 12 = 32 marbles.

Answer:

not factorable

Step-by-step explanation:

To factor a trinomial of the type x^2 + ax + b, you need to find two numbers that add to a and multiply to b.

You have 1x^2 + 9x + 2.

In this case, a = 9 and b = 2.

There are no two integers whose sum is 9 and whose product is 2, so this trinomial is not factorable.

Answer:In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.

Step-by-step explanation:

The slopes of two parallel lines are always equal.

The slope of a line can be calculated by taking the tangent ratio of the angle formed by it with the x axis.

The angle between two parallel lines is zero.

It implies that they form same angle with the x-axis.

Since, the slope of a line is define as the tangent of the angle made by it with x axis.

The slopes of the parallel lines will be equal.

Suppose the slopes of two parallel lines are m₁ and m₂.

Then, it can be written as m₁ = m₂.

Hence, the relationship between the slopes of two parallel lines can be written as m₁ = m₂.

Answer:

Position s(t) = -16t² + 1250 ft

Step-by-step explanation:

Given that:

initial height h₀ = 1250 feet

and suppose the position  function is given as:

-16t² + v₀t + h₀

here;

v₀ = initial velocity

t = time

Thus, the position formula can be expressed as:

Position s(t) = -16t² + 1250 ft because v₀ = 0 ft/s and h₀ = 1250 feet

therofore the slope = 3/6 = 1/2

Answer:

- 2 and [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (0, - 1) ← 2 points on the green line

m = [tex]\frac{-1-5}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2

Repeat with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the blue line

m = [tex]\frac{0+3}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Since the product of the slopes = - 2 × [tex]\frac{1}{2}[/tex] = - 1

Then the lines are perpendicular

Answer:

350 6th grade students

Step-by-step explanation:

From the question

At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music.

Total number of sixth graders that love hip-hop = 210

Let the total number of students in the school be represented as: x

Hence,

60% × x = 210

60/100 × x = 210

Cross Multiply

60x = 210 × 100

x = 210× 100/60

x = 350 students.

Therefore, the total number of sixth graders is 350 .

Next to 6 is 9, next to 15 is 27, and next to 3 is 5

Step-by-step explanation:

If you imagine 6 photos for every 2 minutes as a fraction and simplify it, the answer to this would be 3 photos for every 1 minute (basically 3/1). By using this unit fraction, you'll see that you're supposed multiply the amount of minutes by 3, or you can divide the # of photos by 3.

For 3 mins, you multiply that by 3 to get 9 photos.

For 9 mins, you multiply that by 3 to get 27 photos

For 15 photos, you divide that by 3 to get 5 photos.
