Answer:

pair of pants = $53

Step-by-step explanation:

s = shirts

p = pair of pants

eq = equation

eq 1:          7s + 5p = 517

eq 2:           s + p = 89

multiply the equation 2 by 7

eq 3:        7s + 7p = 623

negate equation 1 and add it to the eq 3

      7s + 7p = 623

+    -7s - 5p = -517

             2p = 106

               p = 53

2. ( a + b )

Step-by-step explanation:

The (a + b)2 formula is the algebraic identity used to find the square of the sum of two numbers. To find the formula of the binomial in the form (a + b)2, we will just multiply (a + b) (a + b).

Have prices been going up or down recently? In a seller’s market properties will likely be somewhat overpriced, and in a buyer’s market properties are apt to be underpriced. It all depends on where the market currently sits on the real estate boom-and-bust curve.

Answer:

True

Step-by-step explanation:

The reason why this is true is because it is totally related. In a Shield volcano, the eruption happens with very fast, less dense, and more magma than that which comes from the stratovolcano. In a stratovolcano, most of the things are just ash and toxic gases. So, that's why, the stratovolcano is also more dangerous.

So hence, your answer is True

Step-by-step explanation:

30% * 50

= 30/100 * 50

= 15

Therefore, 30% of the integers between 1 and 50 are in the range 1 to 15

So the random integer generated is in this range, that is, less than or equal to 15, then the weather must be simulated to be rainy.

This would mean that the chance of rain on each day is 30% (if the computer generates the random number consistently)

There are 35 different groups of 4 flowers can Simon choose.

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.

We have,

A client asked him to select 4 of the 7 available flower options.

So, the number of combination for 4 flowers is

C(7, 4)

= 7!/ 4! (7-4)!

= 7 x 6 x 5/ 3x 2

  see the attachments for the graph, and a spreadsheet with midpoints and slopes

Step-by-step explanation:

We are given the coordinates of the vertices of a triangle, and asked to find the parameters of the perpendicular bisectors of the sides of the triangle. The perpendicular bisectors are to be plotted on the graph.

Coordinates A(1, 6), B(5, 4), C(5, -2)

__

a) Graph and label the triangle

b) Find the midpoint of each side of the triangle

c) Find the slope of each side of the triangle

d) Find the slope of each perpendicular bisector

e) Use the midpoint and the perpendicular slope to accurately draw each perpendicular bisector on the triangle

__

See the attached graph for shaded triangle ABC.

__

The midpoint (M) of a segment AB will be ...

  M = (A+B)/2

For example, the midpoint of segment AB is ...

  D = ((1, 6) +(5, 4))/2 = (1+5, 6+4)/2 = (6, 10)/2 = (3, 5)

This repetitive arithmetic is carried out in the spreadsheet shown in the second attachment. The midpoints are ...

  D(3, 5) is midpoint of AB

  E(5, 1) is midpoint of BC

  F(3, 2) is midpoint of CA

__

The slope of a segment is found using the slope formula (or by counting grid squares). That formula is ...

  m = (y2 -y1)/(x2 -x1)

For segment AB, this is ...

  mAB = (4 -6)/(5 -1) = -2/4 = -1/2

The other slopes are calculated similarly in the spreadsheet. When the denominator is zero (a vertical line), the slope is "undefined."

  mBC = undefined

  mCA = -2

__

The slope of the perpendicular line is the opposite reciprocal of the slope of the segment.

  m⟂AB = -1/(-1/2) = 2

  m⟂BC = 0 . . . . . a horizontal line has 0 slope

  m⟂CA = -1/-2 = 1/2

__

The perpendicular bisectors of each of the sides of the triangle are shown in the first attachment. As the lesson title indicates, their point of concurrency is G(1, 1), the circumcenter of the triangle.

Answer:

x ≥ 5

Step-by-step explanation:

  5 + 2(2x - 3) ≥ 3x + 4

Expand brackets:

⇒ 5 + 4x - 6 ≥ 3x + 4

Combine like terms:

⇒ 4x - 1 ≥ 3x + 4

Subtract 3x from both sides:

⇒ x - 1 ≥ 4

Add 1 to both sides:

⇒ x ≥ 5

Answer:  x>=5

Step-by-step explanation:

Simplify the expression

5+2\cdot\left(2x-3\right)>=3x+4

5+2\cdot2x+2\cdot-3>=3x+4

5+4x-6>=3x+4

4x+\left(5-6\right)>=3x+4

4x-1>=3x+4

Group all r terms on the left side of the inequality

x-1>=4

x-1+1>=4+1

x>=4+1

x>=5

Answer:

  5x +4y

Step-by-step explanation:

The perimeter of a triangle is the sum of side lengths. That fact can be used to find z, the length of the third side.

  (2x +3y) +(5x -2y) +z = 12x +5y . . . . sum of sides is perimeter

  z = (12x +5y) -(7x +y) . . . . . . . . . . . . subtract (7x+y) from both sides

  z = 5x +4y . . . . . . . . . collect terms; the length of the third side

The third side of the triangle is (5x +4y).

Answer:

  c.) hourly rate

Step-by-step explanation:

The value the coefficient represents can often be learned from its units. The term 8t gives a value in currency units, since the expression 8t+20 is an amount that is to be paid. (We can only add like terms, so both 8t and 20 must have currency units.)

The value of t has units of hours, so the coefficient 8 must have units that are ...

  8 currency units/hour

That is, multiplying by hours gives currency units.

In this context, a number with units of currency units per hour is most likely the hourly rate of the rental.

The area shaded in green is 864 cm²

Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,

AB / PQ = CD / RS

30 / 10 = 24 / RS

30RS = 240

RS = 240 / 30

RS = 8 cm

let find the height of trapezium PQRS.

AB / PQ  = 36 / h

30 / 10 = 36 / h

30h = 360

h = 360 / 30

h = 12 cm

Therefore,

area of the green portion = area of ABCD - area of PQRS

Therefore,

area of ABCD = 1 / 2(24 + 30)36 =  1 / 2 (54)36 = 1944 / 2 = 972 cm²

area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²

Area of the green portion = 972 - 108 = 864 cm²

Answer:

3/8 seems to be the most relevant answer

Answer:

The surface area of a cylinder is the surface area of rectangular piece of paper as you roll it into a cylinder

and the surface area of the base and top areas:

Assume that you had a rectangular piece of paper with the long side h, and short side w, let h be the height of the cylinder as you roll it, the surface area generated is the circumference of the circle with radius r multiplied by the height = 2 ¶ r h . The area of the top and bottom circular bases is 2 ¶ r2

The total surface area = 2 ¶ r h + 2 ¶ r2  = 2 ¶ r ( h+ r ) to express r in terms of w , w = 2 ¶ r the width of the rectangle equal to the circumference of the circle , then the total surface area = w ( h+ r )

but r = w / 2 ¶ , the surface area = w(h+w/ 2¶) = (wh+ w2/2¶)
