Answer:

first lets find the area of the floor.

A=l*w     where l=length and w=width

Plug in the data

A=14*12

A=168ft²

If 1 square foot of carpet is 2.90$, then 168 square feet are...

 1 sqft         168sqft

_______ = ________

 2.90$             x$

Cross multiply

1x=487.20

divide both sides by 1

x=487.20 dollars

Answer= $487.20

Answer:

43.75

Step-by-step explanation:

25 divided by 100=.25

.25*35=8.75

8.75+35=43.75

The store paid a price of $28 for the item.

Mark up percentage is the percentage of profit on a certain service or commodity.

We know the formula to calculate mark up percentage.

Mark up Percentage = [(Selling price - Cost) / cost] × 100

Here, given that,

Mark up percentage = 25%

Selling price = $35

We have to find the cost.

Let x be the price that the store paid for the item.

Substitute the given values in the formula for mark up percentage.

25 = [(35 - x) / x] × 100

Dividing both sides of the equation by 100,

25/100 = (35 - x) / x

0.25 = (35 - x) / x

Multiplying both sides with x,

0.25x = 35 - x

Adding both sides with x,

0.25x + x = 35

1.25x = 35

Dividing both sides by 1.25,

x = 35 / 1.25

x = 28

Hence the price of the item that the store paid is $28.

Answer:

100.3 square units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of circle

Note: 2 semicircles = 1 full circle

Area of the figure = a*h + πr²

Where,

a = 10

h = 5

r = ½ of 8 = 4

Plug in the value into the equation

Area = 10*5 + π*4²

Area = 50 + π*16

Area = 100.265482 ≈ 100.3 square units (nearest tenth)

Step-by-step explanation:

Simplifying

6x + 4y = 6

Solving

6x + 4y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

6x + 4y + -4y = 6 + -4y

Combine like terms: 4y + -4y = 0

6x + 0 = 6 + -4y

6x = 6 + -4y

Divide each side by '6'.

x = 1 + -0.6666666667y

Simplifying

x = 1 + -0.6666666667ySimplifying

6x + 4y = 6

Solving

6x + 4y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

6x + 4y + -4y = 6 + -4y

Combine like terms: 4y + -4y = 0

6x + 0 = 6 + -4y

6x = 6 + -4y

Divide each side by '6'.

x = 1 + -0.6666666667

Simplifying

x = 1 + -0.6666666667

Simplifying

2x + 5y = 9

Solving

2x + 5y = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5y' to each side of the equation.

2x + 5y + -5y = 9 + -5y

Combine like terms: 5y + -5y = 0

2x + 0 = 9 + -5y

2x = 9 + -5y

Divide each side by '2'.

x = 4.5 + -2.5y

Answer:

CED=126

Step-by-step explanation:

The total of all 3 angles should be 180

so:

180-38-16 (ABC is equal to ECD)

180-38-16=126

126=CED

Answer:

∠E= 126°

Step-by-step explanation:

the parallel lines create a transversal (the diagonal line that connects them)

this transversal rule shows us that

∠DCE=∠CBA

so ∠DCE= 38°

let's look at the triangle

∠C+∠D+∠E=180°

38+16+∠E= 180°

∠E= 126°
