Generally, Angle in a triangle is 180^{\circ}

Therefore

45+68+x=180

x=180-(45+68)

x=67

The angle on a line is also 180^{\circ}

x+z =180

67+z =180

z =180-67

z =113

In conclusion

180=113+12+y

-180-(113+12)=y

y=55

Answer: 247 miles.

Step-by-step explanation: First, we need to convert the 45 minutes into hours. we know that 1 hour = 60 minutes. Dividing any number of minutes by sixty gives us the number of hours along with the remaining minutes if there are any. so 45/60 simplifies to 3/4. Now for the miles, it's given that the speed is 52 mph. So we can put into the expression 52(4+3/4)= total miles. Once we distribute 52, we get 208 + 39, which equals to 247.

Answer:

247

Step-by-step explanation:

52÷60 mins x 45= 39 miles for 45 mins

45 mins + 4 x 52 =247

Answer:

Step-by-step explanation: Let x be the smaller and y be the largest number.

Since x+y=13, we deduce y=13-x

Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x

Their sum is y+2+2x

And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x

We get that the value of  (f + g​)(x​) is 3 x² - 2 x - 10 and (f + g​)(6​) is 86.

We are given the two functions:

f(x) = 3 x² - x - 6

g(x) = x - 4

We need to find:

(f + g​)(x​)

= f(x) +g(x)

= 3 x² - x - 6 + x - 4

= 3 x² - 2 x - 10

Now we have to find:

(f + g​)(6​).

Put x = 6, we get that:

= 3 (6)² - 2 (6) - 10

= 108 - 12 - 10

= 108 - 22

= 86

Therefore, we get that the value of  (f + g​)(x​) is 3 x² - 2 x - 10 and (f + g​)(6​) is 86.

Answer: D': (-7, -1)

E': (-6, -1)

F': (-6, -10)

G': (-7, -10)

Step-by-step explanation:

In a 90 degree clockwise rotation about the origin for this rectangle, the x and y coordinates of the rectangle's edges are swapped, but the y-coordinates are negated. This is because the transformation is happening to the 3rd quadrant, where both the x and y values will be negative.

D: (1, -7) ==> (-7, 1) ==> D': (-7, -1)

E: (1, -6) ==> (-6, 1) ==> E': (-6, -1)

F: (10, -6) ==> (-6, 10) ==> F': (-6, -10)

G: (10, -7) ==> (-7, 10) ==> G': (-7, -10)

the maximum number of candy kisses that each person could have received is 4.

We know that each person receives the same number of candy.

Then the quotients between the number of candy and the number of people should give the same value:

20/K = 52/N

Let's find the common factors between 20 and 52, to do so, we need to rewrite the two numbers as a product of prime factors:

20 = 2*10 = 2*2*5

52 = 2*26 = 2*2*13

The greatest common factor between 20 and 52 is (2*2) = 4

Then, if each person receives 4 candy:

The group that receives 20 candy:

20/K = 4

20/4 = k = 5

That group has 5 people.

The group that receives 52 candy:

52/N = 4

52/4 = N = 13

This group has 13 people.

Then the maximum number of candy kisses that each person could have received is 4.

Step-by-step explanation:

D.16

The number of vehicle administered by department A only = 18

The number of vehicle administered by department B only = 8

The number of vehicle administered by department C only = 1

Given data

50 vehicles belong to an enterprise that has three departments, A, B and C

6 vehicles are available for the use of all three departments

2 vehicles give service to neither of the departments

24 vehicles are administrated by department B

16 of the 24 used by B are also used by the others departments

There are twice as many vehicles in department A as there are in department C.

equal numbers of vehicles are allocated when used by any two departments

number of vehicles on department A = 2 * number of vehicles in department C.

say A = 2C

B = 24

let x represent the number of vehicles used by any two departments

16 of the 24 used by B are also used by the others departments and equal numbers of vehicles are allocated when used by any two departments hence

16 = 2x + 6

2x = 16 - 6

2x = 10

x = 5

B only = 24 - 2x - 6 = 18 - 2x = 18 - 10 = 8

A only = A - 2x - 6 = 2C - 10 - 6 = 2C - 16

C only = C - 2x - 6 = C - 10 - 6 = C - 16

adding up all the vehicles as allocated to get to the sum of 50

24 - 2x - 6 + A - 2x - 6 + C - 2x - 6 + x + x + x + 6 + 2 = 50

24 - 6 - 6 - 6 + 6 + 2 - 2x - 2x - 2x + x + x + x + A + C = 50

24 - 10 - 6x + 3x + 2C + C = 50

14 - 3x + 3C = 50

3C - 3X = 50 - 14

3C - 3(5) = 36

3C - 15 = 36

3C = 36 + 15 = 51

C = 17

C only

C only = C - 16

C only = 17 - 16

C only = 1

A only
A only = 2C - 16

A only = 2 * 17 - 16 = 34 - 16 = 18

The number of vehicle administered by department A only = 18

The number of vehicle administered by department B only = 8

The number of vehicle administered by department C only = 1

The number of vehicle administered by department A = 2C = 34

The number of vehicle administered by department B = 24

The value of g(h(10)) is 2√2. the correct option is A.

Given that the functions are g(x)=√x-4 and h(x)=2x-8.

A function is defined as the relationship between a set of inputs where each input has an output.

Firstly, we will find the value of h(10) by substituting x=10 in the function h(x)=2x-8.

h(10)=2(10)-8

h(10)=20-8

h(10)=12

Now, we will find g(h(10)) where h(10)=12.

By substituting h(10)=12 in g(h(10)), we get

g(h(10))=g(12).

Further, we will find g(12) by substituting x=12 in the function g(x)=√x-4, we get

g(12)=√(12-4)

g(12)=√8

g(12)=2√2

Hence, the value of function g(h(10)) when g(x)=√x-4 and h(x)=2x-8 is 2√2.

The vertical distance of helicopter from the ground is equal to 2000 / 3 m.

Let the distance between the two planes A and B be x.

In △ ADC, we get that:

tan 60° = 2000 / y

√3 = 2000 / y  ...(1)

Now, in △ BCD, we get that:

tan 30° = 2000 - x / y

1 / √3 = (2000 - x) / y    ... (2)

Divide (1) from (2):

3 = 2000 / (2000 - x)

6000 - 3 x = 2000

3 x = 6000 - 2000

3 x = 4000

x = 4000 / 3

(2000 - x) = 2000 - 4000/3 = 2000 / 3

Therefore, the vertical distance of helicopter from the ground is equal to 2000 / 3 m.

Given dimensions of rectangle ABCD:

[tex]\begin{aligned}\textsf{Area of a rectangle} & = \sf width \times length\\\\\implies \sf Area\:of\:ABCD& = x(x+4)\\& = x^2+4x \end{aligned}[/tex]

Given dimensions of isosceles triangle ADE:

[tex]\begin{aligned}\textsf{Area of a triangle} & = \dfrac{1}{2} \times \sf base \times height\\\\\implies \textsf{Area of $\triangle$ADE}& = \dfrac{1}{2} \cdot x \cdot x\\& = \dfrac{1}{2}x^2\end{aligned}[/tex]

As the area of the portion remaining when ADE is cut off from ABCE is 6 m²:

[tex]\begin{aligned}\sf ABCD-ADE & = 6\\\implies x^2+4x-\dfrac{1}{2}x^2 & = 6\\2x^2+8x-x^2 & = 12\\x^2+8x & = 12\\x^2+8x-12 & = 0\end{aligned}[/tex]

Solve the found quadratic equation by completing the square.

Move the constant to the right side of the equation:

[tex]\implies x^2+8x-12+12=0+12[/tex]

[tex]\implies x^2+8x=12[/tex]

Add the square of half the coefficient of x to both sides:

[tex]\implies x^2+8x+\left(\dfrac{8}{2}\right)^2=12+\left(\dfrac{8}{2}\right)^2[/tex]

Simplify:

[tex]\implies x^2+8x+4^2=12+4^2[/tex]

[tex]\implies x^2+8x+16=12+16[/tex]

[tex]\implies x^2+8x+16=28[/tex]

Factor the perfect square trinomial on the left side:

[tex]\implies (x+4)^2=28[/tex]

Square root both sides:

[tex]\implies \sqrt{(x+4)^2}=\sqrt{28}[/tex]

[tex]\implies x+4=\pm \sqrt{28}[/tex]

[tex]\implies x+4=\pm \sqrt{4 \cdot 7}[/tex]

[tex]\implies x+4=\pm \sqrt{4}\sqrt{7}[/tex]

[tex]\implies x+4=\pm 2\sqrt{7}[/tex]

Subtract 4 from both sides:

[tex]\implies x=-4\pm 2\sqrt{7}[/tex]

As length is positive:

[tex]\implies x=-4+ 2\sqrt{7}\:\:\sf only[/tex]

Taking the value of √7 = 2.65:
