Answer:

Step-by-step explanation:

The total circumference of the circle is: C = 2*pi*radius = 2*(3.14159)*(6) = 37.7 m The total circle has 365o.  Your arc has only 135o.  Hence: 135o           x-------  =  -------------365o          37.7 m where x is the length of the 135o arc.  Solve for x.

Answer:

40%

Step-by-step explanation:

Let x = numerator

Let y = denominator

[tex]\implies \dfrac{x}{y}[/tex]

Decreased by 30% = 100% - 30% = 70% = 70/100 = 0.7

Decreased by 50% = 100% - 50% = 50% = 50/100 = 0.5

[tex]\implies \dfrac{0.7x}{0.5y}[/tex]

[tex]\implies \dfrac{0.7}{0.5}=1.4[/tex]

[tex]\implies 1.4 \ \dfrac{x}{y}[/tex]

1.4 as a percentage = 1.4 x 100 = 140%

Therefore, the percentage increase is 140 - 100 = 40%

Answer:

A unit rate has a denominator of 1 unit when the rate is written as a fraction. To write a rate as a unit rate: divide the numerator and the denominator of the rate by the denominator. Example #1: A rate compares two quantities of different units. Each part of the rate must be labeled!

Real life situations can be represented using mathematical statements

Examples of real life situations of things more than 100% are:

When something is greater than 100%, then there is an increment in the thing.

Take for instance, a unit of apple that was sold at $4 is not $10.

The percentage change is 150%

Other possible scenarios are when the area of a garden is enlarged and when you increase your weekly savings by more than 100%

Answer:

The area is 77 ft.

Step-by-step explanation:

The formula for area of a trapezoid is 1/2 (base1 + base2) x height.

So, 1/2 (14+8) x 7 = 77.

Answer:

77Ft

if we were to ignore the extra "space" or area, and just do the area of the square we would get 8x7, but you probably want to know how I figured the area of both triangles, well this is simple the triangle has a height of 7 while it has a base(bottom) of 3 since 14-8(top)=6 and there are two triangles and they are the same lenght, when there is a triangle we do the base x height then divide by 2 since it's half a square so we do in this situation 3x7=21 and since there is another triangle we do it one more 3x7=21 add them together 3x7x2=42 then divide this by 2 and we get 21, we then add this to 56 which is the area of the square and get our result 77ft

Answer:

7.0

Step-by-step explanation:

When doing trigonometry, remember SOH-CAH-TOA...

Sine : Opposite/Hypotenuse

Cosine : Adjacent/Hypotenuse

Tangent : Opposite/Adjacent

In this figure, we are given the measure of a 23° angle, and two sides that are opposite of the angle, and the hypotenuse.

This means we need to use sine:

[tex]sin(23)=\frac{x}{18}[/tex]

Multiply both sides by 18:

[tex]18sin(23)=x[/tex]

[tex]18(0.391)=x\\x=7.038\\x\approx7.0[/tex]

Answer:

  (8, 63)

Step-by-step explanation:

The ordered pair is a solution to the equation when substituting the values for x and y make the equation a true statement.

If we let x represent the first number of the ordered pair, it will be a solution when ...

  63 = 9x -9

  7 = x -1 . . . . . . . divide by 9

  8 = x . . . . . . . add 1

The blank gets filled with 8, so the ordered pair is (8, 63).

Step-by-step explanation:

[tex]12.45=4.95+0.5\timesx[/tex]×x

Solve the equation

[tex]12.45=4.95+0.5x[/tex]

Rearrange variables to the left side of the equation

[tex]-0.5x=4.95-12.45[/tex]

Calculate the sum or difference

[tex]-0.5x=-7.5[/tex]

Divide both sides of the equation by the coefficient of variable

[tex]x=\frac{-7.5}{-0.5}[/tex]

Determine the sign for multiplication or division

[tex]x=\frac{7.5}{0.5}[/tex]

Multiply both the numerator and denominator with the same integer

[tex]x=\frac{75}{5}[/tex]

Cross out the common factor

[tex]x=15[/tex]

The volume of the resulting prism is 3.375 times of original volume.

The factor by which the dimensions of an object are enlarged is called the scale factor.

Let us take the base area of Prizm = a²

Height of the prism = h

Enlarged area = (scale factor)² * previous area

Enlarged area = 1.5²*a² = 2.25a²

Enlarged height = 1.5h

So, enlarged volume = enlarged area* enlarged height

Enlarged volume= 2.25a²*1.5h = 3.375a²h

Enlarged area/previous area = 3.375a²/a² = 3.375

Therefore, the volume of the resulting prism is 3.375 times of original volume.

(c) negative

(d) 5

Step-by-step explanation:

(a)  A function is "decreasing" when the y-value decreases as the x-value increases.

⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)

(b) Local maxima are the points on the function where it reaches a maximum.

⇒ maxima at x = -6 and x = -2
