Given L || M find the value of unknown angles in each of the following figures​

The geometry object known as a line extends on both sides and is defined as an object with zero width. Any line without curves is said to be straight.

An object with zero width that extends on all sides is referred to as a line in geometry. Simply put, a straight line is an uncurved line. As a result, a straight line is one without any curves that stretches to infinity on both sides.

A line is a perfectly straight, one-dimensional shape that is endlessly long and thin in both directions. A line may be referred to as a straight line or, more formally, a right line (Casey 1893), to stress that there are no "wiggles" throughout its entire length.

y=mx+c

Definition. Y=mx+c is the formula for a straight line. m is the gradient and c is the height, commonly known as the y-intercept, at where the line crosses the y-axis in the equation y = m x + c.

[tex](b) $\because$ perpendicular makes an angle of $60^{\circ}$ with the line $x+y=0$.$\therefore$ the perpendicular makes an angle of $15^{\circ}$ or $75^{\circ}$ with $x$-axis.[/tex]

[tex]Hence, the equation of line will be $x \cos 75^{\circ}+y \sin 75^{\circ}=4$or $x \cos 15^{\circ}+y \sin 15^{\circ}=4$$(\sqrt{3}-1) x+(\sqrt{3}+1) y=8 \sqrt{2}$or $\quad(\sqrt{3}+1) x+(\sqrt{3}-1) y=8 \sqrt{2}$[/tex]

Answer:

Since the calculated value of t =4.629 falls in the critical region t> 2.355 we  reject the null hypothesis and  conclude that method 1 was more successful than method 2 at the 1% level.

Step-by-step explanation:

Applying two sample t test as both methods are independent

The null and alternate hypotheses are

H0: u1= u2   against the claim Ha: u1> u2

The significance level is 0.01 and the critical region is  t > t∝( n-1)

The degrees of freedom is calculated using the formula

υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1

This formula is used when the the variances are unequal.

So as we do not know anything about variances we assume they are unequal.

The calculated degrees of freedom is 132

The critical region is t >  2.355 for one tailed test.

The test statistic is

t= x1`- x2`/ √s1²/n1 + s2²/n2

t= 85-83/ √3²/75+ 2²/60

t= 2/ 0.432

t= 4.629

Since the calculated value of t =4.629 falls in the critical region t> 2.355 we  reject the null hypothesis and  conclude that method 1 was more successful than method 2 at the 1% level.

Answer:

Answer:

The volume of a cylinder with diameter 8 and height 10 is 502.65.

The volume of a cylinder with radius 7 and height 4 is 615.75.

The volume of a cone with radius 18 and height 6 is 2035.75.

The volume of a cone with diameter 12 and height 8 is 1206.37.

Answer:

To solve this equation, we first need to isolate the ln term on one side of the equation. To do this, we can subtract ln 4 from both sides to get:

ln 4 - ln x - ln 4 = 2 - ln 4

This simplifies to:

-ln x = 2 - ln 4

Next, we can add ln 4 to both sides to get:

-ln x + ln 4 = 2

This simplifies to:

ln 4 - ln x = 2

Now, we can apply the identity ln a - ln b = ln(a/b) to both sides of the equation to get:

ln(4/x) = 2

To solve for x, we can apply the inverse logarithm function (exp) to both sides:

4/x = exp(2)

This simplifies to:

x = 4/exp(2)

Finally, we can evaluate this to get the value of x:

x = 4/exp(2) = 4/7.38905609893065

So the solution is x = 4/7.38905609893065.

5, 6, 7, 8, 11, 11, 15

The middle number is 8.

Answer:

8

Step-by-step explanation:

Answer:

Basically, LON would be 8z + 112 + 6z - 17

So, our equation will look like this

8z + 112 + 6z - 17 = -1z + 65

Subtract the 6z from the 8z

2z + 112 - 17 = -1z + 65

112 - 17 = 95

2z + 95 = -1z + 65

add the 1z

3z + 95 = 65

subtract the 95

-30

3z = -30

The answer is -10 :)

Step-by-step explanation:

Answer:

LON=75

Step-by-step explanation:

LON= LOM=NOM

-1z+65=8z+112-6z-17

-1z+65=2z+95

3z=-30

z=-10

LON= -1z+65

       = -1(-10)+65

       = 10+65

LON= 75

Answer: 1000 times less

Step-by-step explanation: multiply 0.054x1000

Answer:

1000 times

Step-by-step explanation:

To find how many times less 0.054 is than 54,

we can divide 54 by 0.054.

This gives us 54/0.054 = 1000

This means that 0.054 is 1000 times less than 54.

Things to keep in mind:

    R - Radius

    A - Area

    Pi = 3.14

Step-by-step explanation:

A = Pi * R^2 = 3.14 * 7^2 = 3.14 * 49 = 153.86‬ (cm^2)

The solution is :

153.86‬ cm^2 or 154 cm^2 (if you round it up), is the circle's area.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

Things to keep in mind:

   R - Radius

   A - Area

   Pi = 3.14

now, given that,

The radius of a circle is 7 centimeters.

i,e. R = 7

so, we get,

A = Pi * R^2

  = 3.14 * 7^2

  = 3.14 * 49

  = 153.86‬ (cm^2)

Hence, 153.86‬ cm^2 or 154 cm^2 (if you round it up), is the circle's area.

Answer:

Step-by-step explanation:

Let's assume that,

→ Length = 2x

→ Width = x

→ Perimeter = 30

Perimeter of rectangle formula,

→ P = 2(L + W)

Now the value of x will be,

→ P = 2(L + W)

→ 2(2x + x) = 30

→ 2 × 3x = 30

→ 6x = 30

→ x = 30/6

→ [ x = 5 ]

Then required dimensions are,

→ Length = 2x = 2 × 5 = 10

→ Width = x = 5

Hence, these are the dimensions.

Length = 10

width = 5

Given-

Perimeter =30

l=2b........................................................ i

so

P =2(l+b)

here

30 = 2(2b +b)... ... ..............         as l=2b from i

30 = 2*3b

30 = 6b

b= 5

which implies l= 2*5 --->10............................................ from i

so

Length = 10

width = 5

The area of right angle triangle is 36 sq.cm. Whose base 9, Height 8 .

Base is 9 cm.

8 centimeters tall.

Triangle area equals 1/2 x base x height

Triangle's area is 1/2 x 9 x 8 = 36 square centimeters.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.

The surface inside a flat figure is measured by its area. Squares are used to measure area. To obtain the square units, multiply the length by the width.

Given:

A mother is now 2 and a half times old as her daughter Mary.

Four years ago the ratio of their ages was 3:1.

To find:

The present age of the mother.

Solution:

Let x be the present age Mary's mother and y be the present age of Mary.

A mother is now 2 and a half times old as her daughter Mary. So,

[tex]x=2\dfrac{1}{2}y[/tex]

[tex]\dfrac{x}{y}=\dfrac{2(2)+1}{2}[/tex]

[tex]\dfrac{x}{y}=\dfrac{5}{2}[/tex]

It means the ratio of their present age is 5:2. Let 5z be the present age of Mary's mother and 2z be the present age of Mary.

Four years ago the ratio of their ages was 3:1.

[tex]\dfrac{5z-4}{2z-4}=\dfrac{3}{1}[/tex]

[tex]1(5z-4)=3(2z-4)[/tex]

[tex]5z-4=6z-12[/tex]

[tex]-4+12=6z-5z[/tex]

[tex]8=z[/tex]

Now, the present age of the mother is:

[tex]5z=5(8)[/tex]

[tex]5z=40[/tex]

Therefore, the present age of the mother is 40 years.

Therefore , the solution of the given problem of ratio comes out to be  15:73 ratio simplified is 15/73.

A ratio or fraction in math displays how many times one number is contained in another. For instance, the proportion of oranges to lemons in a bowl of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3 or decimal 1.333).

Here,

To simplify the ratio 15:73, we find the greatest common divisor of 15 and 73, and then we divide 15 and 73 by the greatest common divisor.

The greatest common divisor that you can use to simplify 15:73 is 1. Which means the answer to ratio 15:73 simplified is:

Here is the math to illustrate better:

15/1 = 15 and 73/1 = 73
