Step-by-step explanation:

We have to find angle CXY

So,

YE/EX=DY/CX

Therefore XY//CD [Theorem]

Angle D =Angle Y [Corresponding Angles]

Angle E + Angle Y +Angle X=180

Angle X=180-(Angle E + Angle Y)

Angle X=180-(89+48)

Angle X=180-137

Angle X=43

Angle CXY=43 Degree

The ratio of boys to girls in a class is 3:5. There are 32 students in the class. How many students are girls?

Answers

Answer:

20 girls

Step-by-step explanation:

boys : girls  : total

3           5        3+5 = 8

There are 32 students

32/8 = 4

Multiply each term by 4

boys : girls  : total

3*4       5*4     8*4

12        20         32

There are 20 girls

Answer: 20 girls

Step-by-step explanation:

So boys to girls is 3 to 5

It asks for girls in class

Suppose there were 8 people in class, 5/8 of the people would be girls

It states that 32 people are in the class, so do 32 x 5/8 to get 20 girls

anyone know how to do this??

Answer:

csc²(x)

Step-by-step explanation:

csc(x) = 1/sin(x)

sin²(x) + cos²(x) = 1

=> cos²(x) = 1 - sin²(x)

cos(2x) = cos²(x) - sin²(x) = (1 - sin²(x)) - sin²(x) =

= 1 - 2×sin²(x)

=> 2×sin²(x) = 1 - cos(2x)

sin²(x) = 1/2×(1-cos(2x))

=> 1 - cos(2x) = 2×(1/2×(1-cos(2x)) = 2×sin²(x)

=> 2 / (1-cos(2x)) = 2 / (2×sin²(x)) = 1/sin²(x) =

= 1/sin(x) × 1/sin(x) = csc(x)×csc(x) = csc²(x)

What are the diferences between volume & area?

Answers

The area is the amount of space occupied by a two-dimensional flat object in a plane.

Volume is defined as the space occupied by the three-dimensional object.
Mark Brainliest please


Answer

The term Area and Volume can create considerable confusion in understanding the terms. Although they seem to be of like a similar quantity of measurement, in reality, they are very much different from each other. Let us understand the underlying meaning of both terms.

What is the difference between Area and Volume?

Area

It is to be noted that area is always defined in two dimensions or object in a plane.

The area is the amount of space occupied by a two-dimensional flat object in a plane.

It is always measured in square units.

It is measured in 2 dimension



Volume

The volume is always defined for a three-dimensional object.

Volume is defined as the space occupied by the three-dimensional object.

It is always measured in cubic units.

It is measured in 3 dimension



whats the factor:81x3-3000

Answers

aikskdjjsiwwjjjwjwkkwkwkwkwkwkwkwkwkw

Answer:

3(3x - 10)(9x² + 30x + 100)

Step-by-step explanation:

Given

81x³ - 3000 ← factor out 3 from each term

= 3(27x³ - 1000 )← a difference of cubes which factors in general as

a³ - b³ = (a - b)(a² + ab + b²) , then

27x³ - 1000

= (3x)³ - 10³

= (3x - 10)((3x)² + (3x)(10) + 10²)

= (3x - 10)(9x² + 30x + 100)

Then

81x³ - 3000 = 3(3x - 10)(9x² + 30x + 100) ← in factored form

Which statement must be true?
O A. JK = KM
B. AJKM is a 30-60-90 triangle.
O C. KM = 2 .JM
D. AJKM is a 45-45-90 triangle.

Answers

Answer : B

Step-by-step explanation:

Ape

The statement which is true is  KM = 2 .JM, the correct option is C.

What is the right triangle?

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

We are given that;

AJKL is an equilateral triangle

Now,

Using these properties, we can eliminate some of the options.

Option A is false because JK and KM are not equal. JK is half of JL, which is one side of the equilateral triangle AJKL, while KM is a perpendicular bisector of JL.

Option B is false because AJKM is not a right triangle. The angle JAK is 60 degrees, not 90 degrees.

Option D is false because AJKM is not a right triangle. The angle JAK is 60 degrees, not 45 degrees.

Option C must be true because KM bisects JL into two equal parts JM and ML. Since JL is one side of the equilateral triangle AJKL, we have JL = AK = AL. Therefore, JM = ML = JL/2 = AK/2 = AL/2. By Pythagoras’ theorem, we have:

KM^2 = AK^2 - AM^2

KM^2 = (AK/2)^2 - (AL/4)^2

KM^2 = (AK/4)^2 + (AL/4)^2

KM^2 = ((AK + AL)/4)^2

Since AK + AL = 2 * JL,

KM^2 = (JL/4)^2 * 4

KM^2 = (JL/4)^2 * 4

KM = JL/4 * 2

KM = JL/2

Therefore, the answer of the triangle will be KM = 2 * JM.

1. In a class of students the ratio of the number of students who like to play football and the number of students who like to play volleyball is 5:3. If the number of students who like volleyball only is 15 and the number of students who like football only is 35, then a. Find the number of students who like both games. ​

Answers

Answer:

Both sports = 15

Step-by-step explanation:

Remark

What an interesting question. At first I didn't think it was possible. Then I saw the word only. That made all the difference in the world.

Givens

Football only = 35

Volleyball only = 15

Ratio = 5/3

Equation

Let the number of students who play both = x

Volleyball / Football = (x + 15) /(x + 35) = 3/5

Solution

(x + 15) / (x + 35) = 3/5                  Cross multiply

5*(x + 15) = 3(x + 35)                     Remove the brackets

5x + 75 = 3x + 105                        Subtract 3x from both sides

3x            3x

2x + 75 = 105                               Subtract 75 from both sides

      - 75   -75  

2x = 30                                        Divide by 2  

2x/2 = 30/2

x = 15

ΔCAP ∼ ΔHIT. Solve for y, given that b = 19. (Round your answer to 1 decimal place, if necessary.)

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the triangles CAP and HIT are not given. The general explanation to solve sides of similar triangles is as follows;

[tex]\triangle CAP \sim \triangle HIT[/tex] implies that the following sides are similar:

[tex]CA \to HI[/tex]

[tex]AP \to IT[/tex]

[tex]PC \to TH[/tex]

Take for instance:

[tex]CA = y[/tex]     [tex]HI = b[/tex]

[tex]AP = 20[/tex]    [tex]IT = 38[/tex]

Then the solution is:

[tex]CA : HI = AP : IT[/tex]

Substitute values for CA, HI, AP and IT

[tex]y : b= 20 : 38[/tex]

Express as fraction

[tex]\frac{y }{ b}= \frac{20 }{ 38}[/tex]

Multiply both sides by b

[tex]y= \frac{20 }{ 38}*b[/tex]

Substitute 19 for b

[tex]y= \frac{20 }{ 38}*19[/tex]

[tex]y= \frac{20 }{ 2}[/tex]

What is the product of two matrix?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.

Given that, C=[5 9 7] and D= [tex]\left[\begin{array}{ccc}2&-4\\4&0\\1&7\end{array}\right][/tex]

Here, CD = [5×2+9×4+7×1 5×(-4)+9×0+7×7]

Alice wrote down three consecutive even numbers with a sum of 252.
Pat wrote down three consecutive odd numbers. Pat's numbers were larger than Alice's numbers.
The difference between the largest odd number and the largest even number was 25.

Answers

Answer:

Alice: 82, 84, 86

Pat: 103, 105, 107

Step-by-step explanation:

Alice:

x + (x+2) + (x+4) = 252

3x + 6 = 252

3x = 246

x = 82 so Alice's last term is 82+4 = 86

Pat:

y + (y+2) + (y+4) = Pat's Total

Pat's last term is (y+4) so

Alice's last term + 25 = Pat's last trem

86 + 25 = 111 = y+4

y = 107
