Answer:

The answer is B. (-7,-2)

Step-by-step explanation:

Multiply the first equation by 7,and multiply the second equation by -6.

7(−3x+6y=9)

−6(5x+7y=−49)

Becomes:

−21x+42y=63

−30x−42y=294

Add these equations to eliminate y:

−51x=357

Then solve−51x=357for x:

−51x=357 Divide both sides by -51

x=-7

Write down an original equation:

−3x+6y=9

Substitute−7forxin−3x+6y=9:

(−3)(−7)+6y=9

6y+21=9(Simplify both sides of the equation)

6y+21+−21=9+−21(Add -21 to both sides)

6y=−12

y=-2

Step-by-step explanation:

The ground speed (G) is given as

[tex]G = \sqrt{(600\dfrac{\sqrt3}{2} + 20)^2 + (300 + 40 \dfrac{\sqrt3}{2})^2}[/tex].

The correct potion is B.

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

An airplane is flying in the direction of 30 degrees South of West at 600 mph. A wind is blowing in the direction of 60 degrees North of East at 40 mph.

It means the airplane is flying in the opposite direction of the wind.

The component of an airplane will be

[tex]\rm x = - 600\ sin 30\\\\x = - \dfrac{600}{2}= -300\\\\y = -600 \ cos30\\ \\y= -\dfrac{600 \sqrt{3}}{2}[/tex]

The component of wind will be

[tex]\rm x = 40 cos 60\\\\x = \dfrac{40}{2} = 20 \\\\y = 40sin 45\\ \\y= \dfrac{40\sqrt3}{2}[/tex]

Then the ground speed will be

[tex]G = \sqrt{(600\dfrac{\sqrt3}{2} + 20)^2 + (300 + 40 \dfrac{\sqrt3}{2})^2}[/tex]

Then the correct potion is B.

Step-by-step explanation:

Given that:

Number of basic instincts present = 66

Number of choices = 2

Using combination :

nCr = n! / (n - r)! r!

66C2 = 66! / (66 - 2)!2!

66C2 = 66! / 64!2!

66C2 = (66 * 65) / 2

66C2 = 2145 different personalities

Answer:

[tex]TG = 2.2[/tex]

Step-by-step explanation:

Represent Tristan's house with T, his grandparent's with G and his parents with P.

Such that:

[tex]TP = 6[/tex]

[tex]GP = 6.4[/tex]

Required

Find TG

To solve this, we make use of Pythagoras Theorem which is represented as:

[tex]GP^2 = TP^2 + TG^2[/tex]

Substitute values for GP and TP

[tex]6.4^2 = 6^2 + TG^2[/tex]

[tex]40.96 = 36 + TG^2[/tex]

Collect Like Terms

[tex]TG^2 = 40.96 - 36[/tex]

[tex]TG^2 = 4.96[/tex]

[tex]TG = \sqrt{4.96[/tex]

[tex]TG = 2.2[/tex] --- Approximated

Hence, the distance between Tristan ans his grandparent's house is 2.2 miles

Answer:

12.8

Step-by-step explanation:

First cube the 3 to get 27.

Then, multiply 2 by 12/5 to get 24/5.

Remove the parentheses and then add 27 with 6 to get 33.

Then divide -24 by 5 to get -4.8.

Add -4.8 with 33 to get 28.2.

Then subtract 15.4 from 28.2 to get 12.8

Answer:

(-1,0) and (8,9)

Step-by-step explanation:

The solution will be obtained when f(x) = g(x)

Mathematically;

x + 1 = x^2-6x-7

x^2-6x-x-7-1 = 0

x^2-7x-8 = 0

x^2-8x + x -8 = 0

x(x-8) + 1(x-8) = 0

(x+1)(x-8) = 0

x = -1

x = 8

so let us get the f(x) and g(x) values

For x + 1

-1 + 1 = 0

8 + 1 = 9

Points are;

(-1,0) and (8,9)

Answer:

3 beverages, 5 appetizers, 8 entrees, and 4 desserts.

Step-by-step explanation:

I think you meant 20 items, so let's do that. To find 15% of 20, we multiply 20 by .15. This gets us 3. We repeat this with all the other numbers, using different decimals, of course. We get 3 beverages, 5 appetizers, 8 entrees, and 4 desserts. 3 + 5 + 8 + 4 is 20, so everything checks out.

Answer:

AB = 3 and AC = 4

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{WX}[/tex] = [tex]\frac{BC}{WY}[/tex] , substitute values

[tex]\frac{AB}{30}[/tex] = [tex]\frac{3}{30}[/tex] ( cross- multiply )

30AB = 90 ( divide both sides by 30 )

AB = 3

and

[tex]\frac{AC}{XY}[/tex] = [tex]\frac{BC}{WY}[/tex] , substitute values

[tex]\frac{AC}{40}[/tex] = [tex]\frac{3}{30}[/tex] ( cross- multiply )

30AC = 120 ( divide both sides by 30 )

AC = 4

Answer:

Step-by-step explanation:

Given

ΔWXY ~ ΔBAC

Therefore, the triangles are similar, so corresponding sides would be in the same ratio, so

WY/ BC = XW/AB

substitute WY = 30, BC = 3, XW = 30, AB = x

30 / 3 = 30 / x

x = [30 × 3] / [30]

x = 90 / 30

x = 3

Thus,

AB = 3

now

WY/ BC = XY/AC

substitute WY = 30, BC = 3, XY = 40, AC = y

30 / 3 = 40 / y

y = [40 × 3] / [30]

y = 120 / 30

y = 4

Thus,

AC = 4

Therefore,

Answer:

52 units.

Step-by-step explanation:

Use the Triple 5-12-13

20 / 4 = 5

48/ 4 = 12

So  the hypotenuse = 4 * 13 = 52.

The lengths of Hypotenuse 52 units.

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

The measurement of two sides are 20 units and 48 units.

Now, Using Pythagoras theorem

H² = P² + B²

H² = 20² + 48²

H² = 400 + 2304

H² = 2704

H = 52 units.

Hence, lengths of Hypotenuse 52 units.
