Franklin saved money to buy art supplies
Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had  \frac{3}{10} of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount  be x

then ,

x =  1- (amount used on buying brushes + amount used for buying paints)

x = 1- (\frac{1}{5} + \frac{1}{2})

x = 1- (\frac{2+5}{10})

x = 1- (\frac{7}{10})

x =\frac{10-7}{10}

x =\frac{3}{10}

A wholesaler requires a minimum of 4 items in each order from its retail customers. The manager of one retail store is consideri
Nataliya [291]

Answer:

  • It is the last graph: solid line, shaded area over the line x = 2 - x/2

Explanation:

1) <u>Set the algebraigic expression that represents the combinations of sofa and pillow orders:</u>

  • Number of sofas: x (given)
  • Number of pillows: 2y (given, since they come in pairs)
  • Number of items = number of sofas + number of pillows = x + 2y
  • Minimum of 4 items in each order (given) ⇒ x + 2y ≥ 4

<u>2) Predict the graph of the inequality x + 2y ≥ 4</u>

  • The border line is the equation x + 2y = 4
  • You can choose two points to draw a line
  • Choose the axis-intercepst:

        x = 0 ⇒ 2y = 4 ⇒ y =4/2 ⇒ y = 2 ⇒ point (0,2)

        y = 0 ⇒ x = 4 ⇒ point (4,0)

        Then the lines goes through (0,2) and (4,0) ... [the four graphs meet this]

  • The shading area is above the line because when you solve for y you get y ≥   2 - x/2, and the line is included because the "equal to" part of the symbol (≥ means greater than or equal to).

  •  To state that the line is included the graph uses a continous line instead of a dotted one.

<u>3) Conclusion:</u>

That means that the correct graph is the last one: solid line, shaded area over the line y = 2 - x/2.

Note: a more detailed graph would include the fact that the items cannot be negative, i.e. x ≥ 0 and y ≥ 0, which would result in that the shaded area would be on the first quadrant.

mezya [45]
Use the Pythagorean theorem:
5^2+x^2=15^2 \\&#10;25+x^2=225 \\&#10;x^2=225-25 \\&#10;x^2=200 \\&#10;x=\sqrt{200} \\&#10;x=\sqrt{100 \times 2} \\&#10;x=10\sqrt{2} \\&#10;x \approx 14.14

The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
