Math help help please

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:

A≈314

Step-by-step explanation:

A=4(pi)r²

A=4(pi)(5)²

A≈314.

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:

Step-by-step explanation:

From the figure

x+159=180°

(linear pair)

x=180-159

x=21°

hope it helps...

have a great day!!

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.

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:

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:

2*x + 2*y ≤ 165 ft

x > 50ft

0ft < y ≤ 20ft

Step-by-step explanation:

For a rectangle with length x and width y, the perimeter of the triangle is:

P = 2*x + 2*y

The perimeter needs to be equal or smaller than the length of fencing that the farmer has, then:

2*x + 2*y ≤ 165 ft

We also know that:

(x strictly larger than 50ft)

x > 50ft

(y can be, at most, 20 ft)

0ft < y ≤ 20ft

(where we added the restriction that y needs to be larger than zero, because we can not have a width equal or smaller than zero)

Then the system of inequalities that represent this situation is:

2*x + 2*y ≤ 165 ft

x > 50ft

0ft < y ≤ 20ft

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.

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)

Got it right on Edge2021

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

3x = 81

x = 81/3

x = 27

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°

Answer:

120

Step-by-step explanation:

The probability of a girl being picked one day = 10/15 = 2/3

Total number of days = 180

Therefore, the nunber of times it will be a girl = 2/3 x 180 = 2 x 60 = 120

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.

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.

Hence, the direction is right

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:

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: did anyone find the answer???

Step-by-step explanation:

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.
