Solve each:
1.

Given:

The figure of a right angle triangle.

To find:

The value of y.

Solution:

in a right angle triangle,

[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]

In the given right triangle,

[tex]\sin 60^\circ=\dfrac{6}{y}[/tex]

[tex]\dfrac{\sqrt{3}}{2}=\dfrac{6}{y}[/tex]

On cross multiplication, we get

[tex]\sqrt{3}y=12[/tex]

[tex]y=\dfrac{12}{\sqrt{3}}[/tex]

[tex]y=\dfrac{12\sqrt{3}}{3}[/tex]

[tex]y=4\sqrt{3}[/tex]

Therefore, the value of y is [tex]4\sqrt{3}[/tex] units.

Answer:

-108

Step-by-step explanation:

(-2)²(-3)³​

When a number has an exponent, it means that the number is being multiplied to itself. For example, in (-2)², it means (-2) multiplied by itself twice since the exponent is 2. And for (-3)³​, it means (-3) multiplied by itself 3 times since the exponent is 3.

= (-2)(-2)(-3)(-3)(-3)

Multiply. Remember that two negative numbers multiplied together make a positive number, and a positive and a negative number multiplied together make a negative.

= (4)(-3)(-3)(-3)

= (-12)(-3)(-3)

= (36)(-3)

= -108

Therefore, the answer is -108.

I hope this helps!

Answer:

x = 42,33°

Step-by-step explanation:

3x + 1° + 52° = 180° [angles on a straight line]

3x + 53° = 180°

3x = 180° - 53°

3x = 127°

divide both sides by 3

x = 42,33°

Answer:

22 cm

Step-by-step explanation:

Answer:

The shape is made up of a square and a rectangle.

So calculating the area of both the figures and then adding them would give us the required result.

Area of square = (a)² = (4)² = 16 sq unit.

Area of rectangle = l×b = 3×2 = 6 sq unit.

Now, the required area = 16 + 6 = 22 sq unit.

Answer:

Step-by-step explanation:

From the figure

x+159=180°

(linear pair)

x=180-159

x=21°

have a great day!!

The probability that the red die shows a six or the green die shows a six is 1136 .

Answer:

6 1/4

Step-by-step explanation:

Add up the fabric that she has

3 1/2 + 6 3/4

Get a common denominator

3 2/4 + 6 3/4

9 5/4

9 4/4 + 1/4

10 1/4

Subtract this from the fabric that she needs

16 1/2 - 10 1/4

Get a common denominator

16 2/4 - 10 1/4

6 1/4

Answer:

The sound of hammering becomes fainter as Nancy goes into her room because some of the sound waves are absorbed by the walls. Only part of the sound waves coming from the other room comes into her room, so the hammering sounds quieter.

I hope this helps. Good luck ^^

Answer:

6.40312424

Step-by-step explanation:

5^2 + 4^2 = c^2

25 + 16 = c^2

41 = c^2

sqrt41 = c

c is equal to about 6.40312424 (round it if you need to)

Answer:

a^2+b^2=c^2

Step-by-step explanation:

5^2+4^2=6.403^2

c= 6.4

Answer:

$28.30

Step-by-step explanation:

= $15.30 + ( 2 × $6.50 )

= $15.30 + $13

= $28.30

Answer:

With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:

C(x)=20+4x,where:

x is the number of rides

The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.

Answer:

36

Step-by-step explanation:

Kendra has 4 so 52-4 (so it's out of the way) now you have 48

Divide 48 by 3 (leaves you 16). It can't be 16 because you have to add 16 and the sum of 16 x 3. So, go down a few numbers

12 + (12x3) = 48 plus Kendra's 4 is 52

Answer:

The midpoint is (-5, -3).

Step-by-step explanation:

Finding the coordinates of the midpoint consists of averaging the x-coordinates of the given points and then doing the same for the y-coordinates.

x coordinate of midpoint = (-9 - 1)/2 = -5

y coordinate = -6/2 = - 3

The midpoint is (-5, -3).

Answer:

A. 7,6,14

Step-by-step explanation:

Rules for side lengths of triangle.

1. Any side should be less then the sum of the other two angles.

2. The same side should be greater than the subtraction of the other side lengths(bigger side - smaller side)

A.

7 < 6+14 .  Correct

7> 14-6 .     Incorrect

This cannot be a solution (impossible)

B.

4<4+4 .  Correct

4>4-4 .  correct

This is a solution (equilateral triangle)

C.

6<6+2 .  Correct

6>6-2 .  Correct

This is a solution (isosceles triangle)

D.

7<8+13 . Correct

7>13-8 . Correct

This is a solution (scalene triangle)

Answer:

129

Step-by-step explanation:

6 rows of chairs * 23 chairs in each row = 138 total chairs.

If 9 of these chairs were removed, that becomes 138 - 9 = 129.

There are 129 chairs left.

Actually Welcome to the concept of Angles.

Here, total angle is 90°.

hence, 90° = x + 57°

so, ==> x = 90° - 57°

x = 33°

hence, x = 33°

Answer:

x=33°

Step-by-step explanation:

90-57=33. Basically, Q is 90°

if you mean that 3x+3=0 then x should equal 0

Answer:

x = 27

Step-by-step explanation:

3x + 3 = 84

3x = 84 - 3
