Answer:

225

Step-by-step explanation:

Clockwise turn:

Southeast to South = 45

South to North = 180

Southeast to North = 180 + 45 = 225

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the concept of Angles.

The direction angle is :-

180° for South to North + 45° for South East to South

so total change in phase is ==> 180°+45° ==> 225°

hence, C.) option is correct

Given:

In triangle ABC, [tex]AB=11x-25,DE=4x+1[/tex].

To find:

The measure of DE.

Solution:

From the given figure, it is clear that D is the midpoint of AC and E is the midpoint of BC. So, the line segment DE is the mid-segment of the triangle ABC.

According to the triangle mid-segment theorem, mid-segment of a triangle is equal to half of its base.

Using triangle mid-segment theorem, we get

[tex]DE=\dfrac{1}{2}AB[/tex]

[tex](4x+1)=\dfrac{1}{2}(11x-25)[/tex]

[tex]2(4x+1)=11x-25[/tex]

[tex]8x+2=11x-25[/tex]

Isolate the variable terms.

[tex]8x-11x=-2-25[/tex]

[tex]-3x=-27[/tex]

[tex]x=\dfrac{-27}{-3}[/tex]

[tex]x=9[/tex]

The value of x is 9. So,

[tex]DE=4x+1[/tex]

[tex]DE=4(9)+1[/tex]

[tex]DE=36+1[/tex]

[tex]DE=36+1[/tex]

[tex]DE=37[/tex]

Therefore, the length of DE is 37 units.

Answer:

Commission earned= $43.95

Step-by-step explanation:

Giving the following information:

Commission rate= 15% = 0.15

Sales= $293

To calculate the commission earned by selling the laptop, we need to use the following formula:

Commission earned= commission rate*sales

Commission earned= 0.15*293

Commission earned= $43.95

Answer:

Total amount spend on DVD = $87

Step-by-step explanation:

Given:

Total number of week = 6 week

Number of DVD purchase per week = 2

Cost of reduced price DVD = $5.50

Cost of regular price DVD = $9

Find:

Total amount spend on DVD

Computation:

Total amount spend each week = Cost of 1 reduced price DVD + Cost of 1 regular price DVD

Total amount spend each week = 5.5 + 9

Total amount spend each week = $14.5

Total amount spend on DVD = Total number of week x Total amount spend each week

Total amount spend on DVD = 6 x 14.5

Total amount spend on DVD = $87

Answer:

 ∠BFC = 50

Step-by-step explanation:

∠AFC = 90

∠AFB + ∠BFC = 90

40 + ∠BFC = 90

           ∠BFC = 90 - 40

          ∠BFC = 50

Answer: B-C

Step-by-step explanation:

I believe it is the angle of B-C becuase B-E is a strieght line which equals 180. Also EFD looks the same as AFB so it is 40. And DFC is 90 becuase of the square. So we take 180-40-90=50. And the only one that is not solved is B-C

Answer:

80+2x=180°{co-interior angle}

2x=180-80

2x=100

x=50°

Answer:

Step-by-step explanation:

ax+b = 0    

The true statement about the end behavior of f(x) is (b)

The equation of the function is given as;

f(x) = -4x^6 +6x^2-52

The leading coefficient of the above function is

Leading coefficient = -4

-4 is less than 0 i.e. negative

This means that options (a) and (c) are false

Also;

The ends of even functions face the same direction, and not opposite directions.

Hence, the true statement about the end behavior of f(x) is (b)

Answer:

29: 7

Step-by-step explanation:

[tex] \frac{8}{3x - y} = \frac{5}{x + 3y} [/tex]

Cross multiply:

[tex]8(x + 3y) = 5(3x - y)[/tex]

Expand bracket:

[tex]8x + 24y = 15x - 5y[/tex]

Bring x terms to 1 side, y terms to the other:

[tex]15x - 8x = 24y + 5y[/tex]

Simplify:

[tex]7x = 29y[/tex]

Divide by 7 on both sides:

[tex]x = \frac{29}{7} y[/tex]

Divide both sides by y:

[tex] \frac{x}{y} = \frac{29}{7} [/tex]

∴ The ratio of x to y is 29:7.

Step-by-step explanation:

if the area is 76.5^2, then all you have to do is take the square root, and it is 76.5

Answer:

12 + 4y is the simplified version of 4(y+3). When you simplify you need to use the distributive property. So, 4 multiplied by y is 4y. 4 multiplied by 3 is 12.  So the answer will be 12 + 4y. Hence, they are equivalent.

Answer:

x = 6√2

Step-by-step explanation:

This is a right triangle, specifically a 45-45-90 one.  Using the Pythagorean Theorem, we get x^2 + x^2 = (12 cm)^2, or:

2x^2 = 144 cm^2, or

x^2 = 72 cm^2.

This comes out to x = 6√2

Answer:      x=-5

Step-by-step explanation:

Distribute

6(x+3)-1(x+4)=-11

6x+ 18-1(x+4)=-11

6x +18-x-4=-11

Subtract the numbers

6x +18-x-4=-11

6x +14-x=-11

Combine like terms

6x +14-x=-11

5x +14=-11

subtract 14 from both sides of the equation

5x +14=-11

5x +=14-14 = -11 -14

simplify

5x=-25

divide both sides

x=-5

Answer:

(x+6)² + (y-6)² = 181

Step-by-step explanation:

equation of the circle in general is (x - a)² + (y - b)² = r²

center is (a, b) in our task a=-6 b=6

so equation of the circle is (x+6)² + (y-6)² = r²

we have point  (3,-4)​ ⇒ x=3 y=-4

put x y in equation of the circle ⇒  (3+6)² + (-4-6)² = r² ⇒r² =181

⇒The equation of a circle is (x+6)² + (y-6)² = 181

Answer:

x²+ y² - 109 = 0

Step-by-step explanation:

The coordinate of centre of circle = (-6 , 6)

Point through which it passes = (3 , -4)

So , Firstly find the distance between the centre and that point that will be equal to the radius . Using Distance Formula we have ,

⇒ D = √ [ ( x - x' )² + ( y + y')² ]

⇒ D = √ [ (3+6)² + (6+4)² ]

⇒ D = √ [ 9² + 10² ]

⇒ D = √ [ 81 + 100 ]

⇒ D = √ 181

⇒ D = 13.45 .

Now substituting the respective values in the general equation of circle .

⇒ ( x - h)² + (y - k)² = r²

⇒ { x - (-6) }² + { y - (6) }² = (13.45)²

⇒ ( x + 6 )² + ( y - 6)² = 13.45²

⇒ x² + 36 + 12x + y² + 36 -12x = 181

⇒ x² + y² + 72 = 181

⇒ x² + y² + 72 - 181 = 0

⇒ x² + y² - 109 = 0
