Answer:

WX < YW < XY

Step-by-step explanation:

Sum of all angles of triangle = 180

  114 + 53 + ∠y = 180

           167 + ∠Y = 180

                   ∠Y = 180 - 167

                  ∠Y = 13

The side opposite to smallest angle is shortest.

Angles in ascending order: ∠Y < ∠X < ∠W

Sides in ascending order: WX < YW < XY

Answer:

75 more girls.

Explanation:-

Given:- Ratio of girls to boys = 5:3

And, the number of boys= 300

Let boys be 4x and girls be 5x

So, 4x = 300 (Given)

x = 300/4 = 75

Thus number of girls:- 5x = 5×75= 375 girls

now you take the 375 girls minus the 300 boys.

375-300 = 75 Girls more

Answer:

Step-by-step explanation:

The limit of the expression [tex]f(x) = \frac{x^2 - 12}{x^2 - 3}[/tex]a s x approaches 3 is -1/2

The expression is given as:

[tex]f(x) = \frac{x^2 - 12}{x^2 - 3}[/tex]

As the variable x approaches 3, the limit is represented as:

[tex]\lim_{x \to 3} f(x)[/tex]

So, we have:

[tex]\lim_{x \to 3} = \frac{3^2 - 12}{3^2 - 3}[/tex]

Evaluate the exponents

[tex]\lim_{x \to 3} = \frac{-3}{6}[/tex]

Evaluate the quotient

[tex]\lim_{x \to 3} = -\frac{1}{2}[/tex]

Hence, the limit of the expression as x approaches 3 is -1/2

[tex]x=-2\pm2\sqrt13[/tex]

Step-by-step explanation:

The area of the triangle is;

[tex]A=\frac{1}{2} \times b\times h[/tex]

[tex]b=x+4[/tex]

[tex]h=x[/tex]

[tex]Area=A=24[/tex]

The ditch is 14.54 feet deep.

Trigonometry can be used to roof a house, to make the roof inclined ( in the case of single individual bungalows) and the height of the roof in buildings etc. It is used naval and aviation industries. It is used in cartography (creation of maps). Also trigonometry has its applications in satellite systems.

As, both brother have height of 6 feet.

We will use the concept of application of trigonometry to find the depth of ditch.

The explanation is attached below

Now, by solving both equations we get

0.8391y= (2+√3)(30-y)

4.5711y=111.96

y= 24.49 feet.

Now,

x= 14.54 feet.

Assuming that L and d are known numbers, we can write.

[tex]W = \frac{49d + 91}{L}[/tex]

Remember that for a rectangle of width W and length L, the area is given by:

A = L*W

In this case, the area is 49d + 91, and the length is a known number, so we know the value of L.

Then we can write:

A = L*W =  49d + 91

To get the value of W, we need to isolate it on one side of the equation.

We can do that by dividing both sides by L.

[tex]W = \frac{49d + 91}{L}[/tex]

We assume that d and L are known, so with the above rational expression, we have W totally determined.

Answer:

Step-by-step explanation:

We have a transversal and lines intersecting with it.

The angle measures formed by the lines and the transversal are not all equal to each other.

Four of the angles measure 85° and one 79°.

These are corresponding angles (the angles which occupy the same relative position at each intersection where a straight line, transversal,  crosses two or more others).

If corresponding angles are equal, the lines are parallel.

In our case all the lines intersecting the transversal are parallel apart from the one with different angle measure.

Step-by-step explanation:

Formula for surface area of a cylinder is 2πrh + 2r²π

2πrh: this is the formula to find the area of the cylinder itself (circumference of the base times the height of the cylinder)

2r²π: this is the formula to find the area of the 2 circles at the end of the cylinder (area of a circle times 2)

We can substitute h with 7 and r with 3 to solve:

2πrh + 2r²π

2(3)(7)π + 2π(3²)

42π + 18π

Answer: 128.7

Step-by-step explanation:

The ratio of the area of sector abc to the area of sector dbe is 4:3

The formula for calculating the area of a sector is expressed as:

A = r²Ф

where:

For the sector ABC

A1 = (2r)²β
A1 = 4r²β

For the sector DBE
A2 = (r)²3β
A2 = 3r²β

Take the ratios

Ratio= A1/A2
Ratio = 4r²β/3r²β
Ratio = 4/3

Hence the ratio of the area of sector abc to the area of sector dbe is 4:3
