A contractor bought 8.2 ft? of sheet metal. She has used 2.3 f? so far and has $177 worth of sheet
metal remaining. The equation 8.2x - 2.3x = 177 represents how much sheet metal is remaining and
the cost of the remaining amount. How much does sheet metal cost per square foot?
Sheet metal costs $ per square foot.

Answers

Answer 1

ANSWER=30

because if you 8.2-2.3 you get  5.9 and if you divide by 177 it is 30

hope it helps

What is an equation of the line that passes through the points -6, -2 and 6,-2

Answers

Answer:

y = 2

Step-by-step explanation:

m = (2 - 2)/(6 - (-6))

m = 0

there's no slope, so it's just 2

As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.

The equation will be just what I said y=2

3w+2=29(Multiply both sides by w)

3w2+2w=29w(Multiply both sides by w)

Answers

Given:

The set of ordered pairs is

{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}

To find:

Which relation has the same domain as the given relation?

Solution:

We know that, domain is the set of input values or x-values.

For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is

Domain={0.5, 1.5, 4.0, 6.5}

Similarly,

For {(1,5),(2,2),(-3,15),(-8,12)},

Domain = {1, 2, -3,-8}

For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},

Domain={0.5, 1.5, 4.0, 6.5}

For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},

Domain = {2, 5, 12, 15}

For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}​,

Domain = {-1, -3, -6, -10}

So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.

Therefore, the correct option is B.

A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%

Answers

9514 1404 393

Answer:

  C)  800%

Step-by-step explanation:

The markup amount is the difference between the selling price and the cost:

  markup = selling price - cost

  markup = $63 -7 = $56

The percentage markup relative to the cost is ...

  markup/cost × 100%

  = ($56)/($7) × 100%

  = 8×100% = 800%

• Demand equation: 0.7x + y = 340
Supply equation: -1.5x + y = 320
1. Solve the system algebraically to determine the balance point between
supply and demand.

Answers

Answer:

Step-by-step explanation:

Subtract equation 2 from equation 1

.7x+y-(-1.5x+y)=340-320

.7x+y+1.5x-y=20

2.2x=20

x=100/11, then use this in either original equation to find y.

.7(100/11)+y=340

y=3670/11, so the balance point is

Which of the following two-dimensional shapes can be rotated to create a sphere?

A. Triangle
B. Square
C. Circle
D. Ellipse

please give an explanation and not just a letter or answer. Thank you.

Answers

The answer is C. circle because a sphere is formed by rotating a circle by any of its diameters

The shape that can be rotated to create a sphere is the circle (option C).

A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.

Let's consider the other options and why they cannot be rotated to form a sphere:

A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.

B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.

D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.

Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.
