Answer:

Both Andre and Mai are correct

Step-by-step explanation:

A drawing of the the triangle ΔABC is created with MS Visio and attached here

In the drawing, we have;

Segment AB = x

Segment AC = 6

By trigonometric ratio, in a right triangle we have;

[tex]Tan(\angle X) = \dfrac{The \ length \ of \ the \ opposite \, side \ to \ \angle X }{The \ length \ of \ the \ adjacent\, side \ to \ \angle X}[/tex]

Where 'X' = 12° as shown in the figure, we have;

[tex]tan(12 ^{\circ}) = \dfrac{AB}{BC} = \dfrac{x}{6}[/tex]

Therefore, Andre is correct

Similarly, we have;

[tex]tan(78 ^{\circ}) = \dfrac{BC}{AB} = \dfrac{6}{x}[/tex]

Therefore, Mai is also correct

Therefore, Andre and Mai are correct.

it can't be greater or equal to so mark off the other ones and we also don't know how many games he played so put a variable beside that 2.5 hope this helps

Answer:

A. 6

Step-by-step explanation:

square root is the number that when multplied by itself will give you the specified amount.

6 x 6 = 36

Step-by-step explanation:

[tex]area = length \times width \\ = (4x + 3) \times (2x + 2) \\ = ( {8x}^{2} + 8x + 6x + 6) \\ = ( {8x}^{2} + 14x + 6) \: {units}^{2} [/tex]

Answer:

[tex](8x + 14x + 6)^{2}[/tex]

Step-by-step explanation:

Area of a rectangle is length x breadth

In the given figure, the length is 2x + 2 and breadth is 4x + 3

So, the area would be:-

(2x + 2) (4x + 3)

[tex]8x^{2}[/tex] + 6x + 8x + 6

So the area would be => [tex](8x + 14x + 6)^{2}[/tex]

Answer:

2x+2y=-4

since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4

6x-2y=12

In this case this equation is incorrect.

Step-by-step explanation:

sorry if I'm incorrect

(please if I'm correct, I really need the brainliest)

Answer:

(1,-3)

or

x=1 y= -3

Step-by-step explanation:

Looking at this we can see that there's a 2y in both of the equations (one is negative while the other is positive and so we'll add them)

so we have

(2x+2y)+(6x-2y)= -4+12

this simplifies to

8x=8

x=1

We know that x=1 and so we will plug this back into one of the two equations

2(1)+2y= -4

2+2y= -4

2y= -6

y= -3

Therefore the solution is (1,-3)

Answer:True

Step-by-step explanation: I did a quiz on it

Answer:

it is true am I right of this question

Answer:

area = 72 yd²

Step-by-step explanation:

area = (4 x 10) + (4 x 8) = 72 yd²

Answer:

Solution given:

f(x) = -3x + 1

f(-2)=-3×-2+1=7

f(0)=-3×0+1=1

f(3)=-3×-3+1=-8

So

Range is {7,1,-8) is a required answer

y=82

Answer:

bc hes a babyyyyy <3333

Step-by-step explanation:

Answer:

x = 4

y = 2√2

Step-by-step explanation:

This triangle can be recognized as a 45 - 45 - 90, right isosceles triangle. The hypotenuse in a right isosceles triangle is √2 times a leg. We can say:

x = √2 * 2√2

x = 4

Since the triangle is isosceles, we can say the legs are equal, therefore:

y = 2√2

Answer: 7/25 or 28%

Step-by-step explanation:

28 (cherry) + 19 (strawberry) + 20 (orange) + 33 (lemon) = 100 (total)

so p(cherry), or the probability of getting cherry, is 28/100 (7/25)

that as a percent is 28%

Answer:

5 ≤ h < 10        = 2

10 ≤ h < 15      = 6

15 ≤ h < 20    = 10

20 ≤ h < 25    = 2

Step-by-step explanation:

Answer:

A= 24

Step-by-step explanation:

First find the scale factor. so the scale factor for these two triangles is 1.5.

21 / 14 = 1.5

18 / 12 = 1.5

So you are going to multiply 16 x 1.5

That will give you 24.

Answer:

circle

Step-by-step explanation:

A semicircle could be created by a plane slicing vertically through a hemisphere.

Geometry is the description of figures in a space with a specific number of dimensions and types. Plane geometry is the most prevalent sort of geometry (dealing with objects like the point, lines, circles, triangles, and polygons),

The plane would cut through the middle of the hemisphere, creating a circle with half the diameter of the original hemisphere. This circle is the base of the semicircle and the curved surface of the hemisphere forms the arc of the semicircle.

Thus, a semicircle could be created by a plane slicing vertically through a hemisphere.

#SPJ2

Step-by-step explanation:

1. We need to find the value of 8.1 × 10³ − 2.4 × 10² in standard form.

We can also write its as :

8.1 × 10³ − 2.4 × 10²

81000 − 240

Standard form = 80760

2.

Amy's weight = 40 kg

Blood comprises 8% of the weight of a human.

Weight of her blood,

Answer:

-5/3 - x = 5/6

-x = 5/6 +5/3

-x/-1 = (5/2)/-1

therefore x = -5/2

therefore -5/2 must be subtracted

Answer:

-6F

Step-by-step explanation: It would be 5F(4hr) = 20F. So if you have 14F subtract 20F you get -6F. Hope this helped.

Answer:

Step-by-step explanation:

P = £1100

r = 5%

t = 6 years

I =P*r*t

[tex]I =1100*\frac{5}{100}*6\\\\I=11*5*6\\\\I = 330[/tex]

Amount = P + I = 1100 + 330 = £1430
