Answer:

Answer: F. 1,275% and 12.75.

Step-by-step explanation:

Ratios

Ratios are usually expressed as decimals, fractions, colon notation, and percentages.

For example, if the ratio of two quantities is 2, it can be expressed as:

2, 2/1, 2:1, 200%

To obtain the percentage expression, just multiply by 100%.

The price of the popcorn sold at a movie theatre was marked up as 12 3/4 times the original cost.

The mixed fraction can be converted to a decimal by just adding their parts as follows:

12 + 3/4 = 12.75

Now to express it as a percentage, multiply by 100%:

12.75 * 100% = 1,275%

Answer: F. 1,275% and 12.75.

Answer:6yb+14x+1 is it Simplify ok

Step-by-step explanation:

Area = (x - 5)(x – 7)

Area = x(x - 7) - 5(x - 7)

Area = x^2 -7x -5x + 35

Area = x^2 -12x + 35

algebraic expression that represents its area: x^2 -12x + 35

x^2 - 12x + 35 = 195

x^2 - 12x + 35 - 195 = 0

x^2 - 12x - 160 = 0

x^2 - 8x - 20x - 160 = 0

x (x + 8) - 20 (x + 8) = 0

(x + 8) (x - 20) = 0

(x + 8) = 0

(x - 20) = 0

x = - 8 (not a solution)

x = 20

hence,

length = x - 5

length = 20 - 5

length = 15 m

width = x - 7

width = 20 - 7

width = 13 m

perimeter = 2(13) + 2(15)

perimeter = 26 + 30

perimeter = 56 m²

The perimeter of the terrain is 56 m²

The area of Rectangle is length times of width.

Given,

The sides of a rectangular terrain are given by the expressions (x - 5) and

(x – 7) meters.

Given area of rectangle is  195 m²

Area of rectangle= (x - 5)  (x - 7)

195=x(x-7)-5(x-7)

195=x²-7x-5x+35

195=x²-12x+35

x²-12x+35-195=0

x²-12x-160=0

x²-8x-20x-160 = 0

x (x+8)-20(x+8)=0

(x-20)(x+8)=0

x=20 and x=-8

Length x-5=20-5=15

x-7=20-7=13

So length is 15m and width is 13m

the perimeter of the terrain =2(Length + width)

=2(15+13)

=2(28)

=56 m²

Hence the perimeter of the terrain is 56 m²

Answer:-3

Step-by-step explanation:

Answer: A: 3 square feet per minute

Step-by-step explanation:

The square feet more that Paula can shovel in 1 minute more than Melinda is 3 square feet per minute.

30x + + 30y = 450 equation 1

20x + 25y = 345 equation 2

Where:

x = square feet shovelled by Melinda

y = square feet shovelled by Paula

The first step is to multiply equation 1 by 20 and equation 2 by 30

600x + 600y = 9000 equation 3

600x + 750 y = 10,350 equation 4

Subtract equation 3 from equation 4

150y = 1350

Divide both sides by 150

y = 9 square meters

Substitute for y in equation 1

30x + 30(9) = 450

30x + 270 = 450

30x = 450 - 270

30x = 180

x = 6 square meters

9 - 6 = 3 square meters

Answer:

{12}

Step-by-step explanation:

isolate the radical expression

[tex]\sqrt{3x} = x-6[/tex]

raise both sides to the index of the radical in this case 2

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

[tex]3x = (x-6)^2[/tex]

foil the right hand side or multiply (x-6)(x-6)

[tex]3x = x^{2} -6x-6x+36[/tex]

subtract 3x from both sides and combine like terms

[tex]0=x^{2} -15x+36[/tex]

factor

[tex]0=(x-12)(x-3)[/tex]

set each factor equal to zero and solve for x

x - 12 = 0 and x - 3 = 0

     x = 12 and     x  = 3

Check each answer by plugging them individually into the original equation if the come out true they are a solution.

Check :

[tex]\sqrt{3(12)}+10=12+4\\\sqrt{36}+10 = 8\\6+10 = 16\\16=16[/tex]           [tex]\sqrt{3(3)}+10=3+4\\\sqrt{9}+10=7\\3+10=7\\13\neq 7[/tex]

Undefined slopes are when x equals a certain number.

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

From the given choices, B is the correct answer.

A has a slope of 0, so m = 0 and would become a horizontal line.

C has a negative slope, so it is not undefined.

D has a positive slope, so it is not undefined.

B shows a vertical line, and so it has an undefined slope.

Answer:

-2

Step-by-step explanation:

find rise over run with y1-y2/x1-x2 = -2/1 = -2

The slope m of the line passing through the points A ( 4 , -3 ) and B ( 3 , -1 ) is m = -2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the first point be A ( x₁ , y₁ ) = A ( 4 , -3 )

Let the second point be B ( x₂ , y₂ ) = B ( 3 , -1 )

Now , the equation for the slope of the line is given by ,

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( -1 - ( -3 ) ) / ( 3 - 4 )

Slope m = 2 / -1

Slope m = -2

Hence , The slope m of the line passing through the points A ( 4 , -3 ) and B ( 3 , -1 ) is m = -2

Step-by-step explanation:

Given that:

Berries in bowl = strawberries and blueberries

Total number of berries = 20

Ratio of blueberries to strawberries = 4 : 1

Number of each berries in bowl:

Total ratio = (4 +1) = 5

Number of Blueberries :

(Ratio of blueberries / total ratio) * number of berries

(4/5) * 20

= 16 blueberries

Number of strawberries :

(Ratio of strawberries / total ratio) * number of berries

(1/5) * 20

= 4 strawberries
