Answer:

2a: 5

2b: 7

2c: 10

2d: 2

2e: 3

2f: 2

Step-by-step explanation:

To solve all of these you just get the variable (x) by itself

2A: 9x-41=39-7x

Add 7x from both sides and then add 41 to get

16x=80

Divide by 16 and get x=5

2B: 3x-13=50-6x It's the same process as before for this question

Add 6x and 13 to both sides to get

9x=63

divide by 9 and get x=7

2C: 5x-17=83-5x

Add 5x and 17 to both sides

10x=100

divide by 10

x=10

2d: 13x-16=24-7x

Add 7x and 16 to both sides to get

20x=40

divide by 20 and get x=2

2e: 12x-13=53-10x

Add 10x and 13 to both sides to get

22x=66

divide by 22 and get x=3

2f: 17x-21=51-19x

Add 19x and 21 to both sides and get

36x=72

divide by 36 and get x=2

Answer:

E. 443.4 ft²

Step-by-step explanation:

Since it is a regular triangle, it means all three sides are of equal lengths and all angles are of the same degree measure.

Therefore, all sides = 32 ft each

Each equal angle = 60° (sum of all angles = 180)

The area of the triangle can be calculated using the formula, ½*a*b*sin(C),

Where,

a = 32 ft

b = 32 ft

C = 60°

Plug in the values

Area = ½*32*32*Sin(60)

Area = 443.4 ft² (nearest tenth)

Answer:

a)60°

b)BD=10

c)AB=20

d)100√3

Step-by-step explanation:

B

let's BD be x

according to the question

[tex] \tan( {30}^{o} ) = \frac{x}{10 \sqrt{3} } [/tex]

[tex] \frac{ \sqrt{3} }{3} = \frac{x}{10 \sqrt{3} } [/tex]

[tex]3x = 10 \sqrt{3} \times \sqrt{3} [/tex]

[tex]3x = 30[/tex]

[tex]x = 10[/tex]

c)

according to Pythagoras theorem

a²+b²=c²

c=√a²+b²

c=√10²+(10√3)²

c=√100+300

c=√400

c=20

D)

the two triangles are congruent

so AC=2(10√3)

=20√3

as we know

area of a triangle =

½bh

=½×20√3×10

=10√3×10

=100√3

Answer:

8.5

Step-by-step explanation:

Given that;

The longest side of an acute isosceles triangle = 12 centimeters

Since the two remaining sides are congruent, then they both have the same length ;

Let the length of the two remaining sides = 2x,

The length of each side :

Length of longest side / sqrt(2)

x = 12 /sqrt(2)

x = 12 / 1.4142135

x =8.4852813

x = 8.5

Answer:

y = 48, x = 11

Step-by-step explanation:

6x = 3x + 33

3x = 33

x = 11

6x + 3x + 33 + y = 180

66 + 33 + 33 + y = 180

66 + 66 + y = 180

132 + y = 180

y = 180 - 132

y = 48

Answer: 0.5 < x < 16.5.

Step-by-step explanation:

Given: Two sides of triangle: 8.0 units and 8.5 units

Measure of third side = x

According to the triangle's inequality,

If x is the third side, then

x < 8+8.5   [Using (i)]

i.e. x< 16.5  

Also, x > 8.5-8   [Using (ii)]

i.e. x> 0.5

Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.

Answer:

0.5, 16.5

Answer:

(-11,-4) and (-5,-7)

Step-by-step explanation:

the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.

Apply the rule to the 1st question by plugging in the coordinates:

(x,y)→(x−7,y+2)

(−4,−6)→((-4)−7,(-6)+2)

(−4,−6)→(-11,-4)

Let's use the same process for the 2nd question:

(x,y)→(x−7,y+2)

(2,−9)→((2)−7,(-9)+2)

(2,−9)→(-5,-7)

Step-by-step explanation:

Answer:

A, D, and F

Step-by-step explanation:

First off, we're not given the hypotenuse's length, so let's use the Pythagorean Theorem to find it:

[tex]1^2+3^2=c^2\\1+9=c^2\\10=c^2\\c=\sqrt{10}[/tex]

With that, we can refer to SOH-CAH-TOA to help us find sine, cosine, and tangent:

SOH (Sine = Opposite/Hypotenuse)

[tex]\sin{\theta}=1/\sqrt{10}=\sqrt{10}/10[/tex]

CAH (Cosine = Adjacent/Hypotenuse)

[tex]\cos{\theta}=3/\sqrt{10}=3\sqrt{10}/10[/tex]

TOA (Tangent = Opposite/Adjacent)

[tex]\tan{\theta}=1/3[/tex]

From this, we can see that A matches up with sine, and we can eliminate B and C.

Cosecant, secant, and cotangent are all reciprocals of the three basic trig ratios:

[tex]\csc{\theta}=1/\sin{\theta}=\sqrt{10}\\\sec{\theta}=1/\cos{\theta}=\sqrt{10}/3\\\cot{\theta}=1/\tan{\theta}=3[/tex]

D matches with cosecant, and F matches with cotangent, so the correct trig rations for θ are A, D, and F.

Answer: 41,250$ (I think)

Step-by-step explanation:

1 hour —> 825$

40 hours —> 825$ x 40 = 33,000$

The after the 40 hours he gets paid x2 and he works for 5 hours

1 hour —> 825$ x 2 = 1,650$

5 hours —> 1650$ x 5 = 8,250$

33,000 + 8,250 = 41,250$
