Answer:

6:5

Step-by-step explanation:

because 30 and 36 can both be divided by 6;

36/6= 6

30/6= 5

so the ratio is 6 to 5

The ratio of 36 nickels to 30 dimes, reduced to its lowest terms, is 6:5.

To write the comparison of 36 nickels to 30 dimes as a ratio reduced to its lowest terms, we need to find the greatest common divisor (GCD) of 36 and 30 and then divide both numbers by the GCD.

Step 1: Find the GCD of 36 and 30:

The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36.

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30.

The common factors are 1, 2, 3, and 6. The greatest common divisor (GCD) is 6.

Step 2: Divide both numbers by the GCD (which is 6):

36 ÷ 6 = 6

30 ÷ 6 = 5

The reduced ratio is 6:5.

So, the ratio of 36 nickels to 30 dimes, reduced to its lowest terms, is 6:5.

Answer:

2x + y - 6 = 0

OR 2x + y = 6

Step-by-step explanation:

First write the equation given in the problem:

y = -2x + 6        This is in slope-intercept form (y = mx + b).

Standard form is written Ax + By + C = 0. When C is a negative number, you might also see it as Ax + By = -C.

The main difference between the two forms in that slope-intercept form isolates the 'y' whereas standard form equates to 0. Don't confuse the 'b' in standard from with the 'B' in slope-intercept form.

To convert from slope-intercept form to standard form, move everything over to the side with 'y'. When you move something, you do its reverse operation to the whole equation. (The reverse of addition is subtraction, the reverse of multiplication is division.)

y = -2x + 6         Do the reverse operations for -2x and +6

y + 2x - 6 = -2x + 2x + 6 - 6      Add 2x and subtract 6 on both sides

y + 2x - 6 = 0            Right side cancels out to be '0'.

2x + y - 6 = 0       Rewrite with the 'x' in front of the 'y'

Here you can see the new equation and what each variable in Ax + By + C = 0 is.

A = 2

B = 1              When a number is not written with the variable, it is 1.

C = -6

Some teachers ask it to be rewritten as Ax + By = -C when 'C' is a negative number.

2x + y = 6

Answer:

No solution.

Step-by-step explanation:

4x + 16y = -19

-2x – 8y = 10         Multiply this equation by 2:

-4x - 16y = 20      Add this equation to the first equation:

0  +    0   = 1

0 = 1

This is absurd so there are no solutions.

Answer:

(x - 3)² = - (y - 14)

The maxima of the function is (3,14).

Step-by-step explanation:

The formula of a quadratic function is given by y = - x² + 6x + 5

We have to write this in the vertex form.

Now, y = - x² + 6x + 5

⇒ y = - (x² - 6x + 9) + 9 + 5

⇒ y - 14 = - (x - 3)²

⇒ (x - 3)² = - (y - 14)  

This is the equation of the parabola in vertex form.

This parabola has the vertex at (3,14) and the axis of the parabola is parallel to the negative y-axis.

Therefore, the maxima of the function is at (3,14). (Answer)

Solving [tex]2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)[/tex] we get [tex]x=\frac{77}{52}[/tex]

Step-by-step explanation:

We need to solve the problem: [tex]2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)[/tex]

Solving:

[tex]2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)\\\frac{9}{4}(4x-1)=\frac{8}{5}(1+4x)\\9x-\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}[/tex]

Add 9/4 on both sides:

[tex]9x-\frac{9}{4}+\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}+\frac{9}{4}[/tex]

[tex]9x=\frac{8}{5}+\frac{9}{4}+\frac{32x}{5}\\9x-\frac{32x}{5}=\frac{8}{5}+\frac{9}{4}\\\frac{9x*5-32x}{5}=\frac{8*4+9*5}{20}\\\frac{45x-32x}{5}=\frac{32+45}{20}\\\frac{13x}{5}=\frac{77}{20}\\x=\frac{77}{20}\times \frac{5}{13}\\x=\frac{77}{4*13}\\x=\frac{77}{52}[/tex]

So, Solving [tex]2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)[/tex] we get [tex]x=\frac{77}{52}[/tex]

Final answer:

The word sentence 'A number x multiplied by 25 is 320' can be translated into the equation 25x = 320. By dividing both sides by 25, we solve for x, which results in x = 12.8.

Explanation:

Good evening ,

Answer:

Step-by-step explanation:

Perimeter of the the square = 4(3x+3) = 12x + 12

perimeter of the pentagon = 5(x+8) = 5x + 40

Step-by-step explanation:

step 1

Find the measure of angle 1

[tex]m\angle 1+65^o=180^o[/tex] ----> by supplementary angles

[tex]m\angle 1=180^o-65^o=115^o[/tex]

step 2

Find the value of x

[tex](10x+5)^o=m\angle 1[/tex] ----> by corresponding angles

substitute

[tex]10x=110\\x=11[/tex]

step 3

Find the measure of angle 2

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

[tex]m\angle 1+m\angle 2+(4x-7)^o=180^o[/tex]

The first picture corresponds the correct dilation by a scale of factor of 1/3 as the image rectangle is reduced and has the coordinates (-2, 0), (0, 2), (2, 0), and  (0, -2) after a rectangle is dilated by a scale of factor of 1/3.

Step-by-step explanation:

A dilation is said to be a transformation which generates an image that is the same shape as the original object, but has a different size.

If the scale factor is greater than 1, then the image will be enlarged. In other words,

If the scale factor is greater than 0 but less than 1, then the image will be reduced. In other words,

Considering the quadrilateral with the vertices (-6, 0), (0, 6), (6, 0) and (0, -6).

According to dilation rule, when a figure is dilated by a scale of factor of 1/3, the the coordinates of that point are multiplied by 1/3. So,

(x, y) → (1/3x, 1/3y)

So, lets apply this on the quadrilateral with the vertices  (-6, 0), (0, 6), (6, 0) and (0, -6).

For (-6, 0)

(x, y) → (1/3x, 1/3y) = (-6, 0) → (-2, 0)

For (0, 6)

(x, y) → (1/3x, 1/3y) = (0, 6) → (0, 2)

For (6, 0)

(x, y) → (1/3x, 1/3y) = (6, 0) → (2, 0)

For (0, -6)

(x, y) → (1/3x, 1/3y) = (0, -6) → (0, -2)

So, the image rectangle will have the coordinates (-2, 0), (0, 2), (2, 0), and  (0, -2) after a rectangle is dilated by a scale of factor of 1/3.

Therefore, the first picture corresponds the correct dilation by a scale of factor of 1/3 as the image rectangle is reduced and has the coordinates (-2, 0), (0, 2), (2, 0), and  (0, -2) after a rectangle is dilated by a scale of factor of 1/3.

So, correct picture is also attached below.

Answer:

Step-by-step explanation:

The total surface area is 125 square yards.

The base area is 37.5 square yards.

Hence, the area of the curved surface is 125 - 37.5 = 87.5 square yards.

According, to the formula, the area of the curved surface is [tex]\frac{5}{2} \times bs[/tex], where b is the base length and s = slant height.

Here, it is given that b = 5 yards.

Thus, [tex]\frac{5\times5\times s}{2} = 87.5\\s = 7[/tex].

130-52=78 dollars

Then later reduce by 25 percent

Now the price is 78 dollars

25/100*78= 19.5 dollar off the new price

So the real price will be

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that, of the 350 people surveyed recently in New York, 68% said they prefer to vacation in Florida.

The number of people will be calculated as,
