24 divided by 3 = 8

Answer:

22.2 feet

Step-by-step explanation:

Treat the ladder, building, and the ground between the bottom of the ladder and the building as the legs of a right triangle.

Then, you can use the Pythagorean Theorem.

X^2 + Y^2 = Z^2

The ladder is the "diagonal" side, so it is the hypotenuse, Z.

It doesn't particularly matter whether the building is X or Y; the end result will be the same.

Therefore:

(23)^2 + Y^2 = (32)^2

Y^2 = (1024 - 529) = 495

Y = 22.249; rounded to the nearest tenth, 22.2 feet

Step-by-step explanation:

First, let's solve the inequality.

Step 1: Subtract 6 from both sides.

Step 2: Divide both sides by 5.

Now that we know x has to be less than 2.6, we can easily assume the largest integer value that satisfies the inequality is when x = 2

Answer:

X= 7 units

Step-by-step explanation:

since the triangles are similar the ratio. of their common sides will be equal so,

BE/BD= BC/BA

Answer:

The second option is correct.

Step-by-step explanation:

Problem 5

------------------

Work Shown:

a = 15

b = unknown

c = 25

a^2 + b^2 = c^2

15^2 + b^2 = 25^2

225 + b^2 = 625

b^2 = 625 - 225

b^2 = 400

b = sqrt(400)

b = 20

The rectangle is a = 15 by b = 20 to get an area of ab = 15*20 = 300 square inches.

=======================================================

Problem 6

Answer:

------------------

Work Shown:

Part A)

area = base*height/2

area = 8*12/2

area = 96/2

area = 48

Part B)

a^2 + b^2 = c^2

8^2 + b^2 = 12^2

64 + b^2 = 144

b^2 = 144 - 64

b^2 = 80

b = sqrt(80)

b = sqrt(16*5)

b = sqrt(16)*sqrt(5)

b = 4*sqrt(5)

Therefore,

area = base*height/2

area = a*b/2

area = 8*4*sqrt(5)/2

area = 16*sqrt(2)

=======================================================

Problem 7

------------------

Work Shown:

area = 81

area = x^2

x^2 = 81

x = sqrt(81)

x = 9

The side lengths of the square are 9 cm each.

P = perimeter

P = 4x

P = 4*9

P = 36

=======================================================

Problem 8

------------------

Work Shown:

The horizontal base of 10 is cut in half to get 5.

a = 5 = horizontal side

b = unknown height

c = 20 = hypotenuse

a^2 + b^2 = c^2

5^2 + b^2 = 20^2

25 + b^2 = 400

b^2 = 400 - 25

b^2 = 375

b = sqrt(375)

b = sqrt(25*15)

b = sqrt(25)*sqrt(15)

b = 5*sqrt(15)

area = base*height/2

area = a*b/2

area = 5*5*sqrt(15)/2

area = 12.5*sqrt(15)

The best ticket deal are illustrations of linear equations

The ticket system is a better deal to the max ticket

From the complete question, we have the following summary:

Charges = $22 per person

Surcharge = $10 per transaction

Charges = $20 per person

Surcharge = $16 per transaction

Assume there would be only one transaction, the linear equations that represent the ticket deals are:

Ticket System: y = 22x + 10

Max Ticket: y = 20x + 16

The costs of ticket for two people in both deals are:

Ticket System: y = 22*2 + 10 = 54

Max Ticket: y = 20*2 + 16 = 56

By comparison;

54 is less than 56

This means that the ticket system is a better deal to the max ticket

Equation

24 students 1 0iece  of pizza each = 25.65

 1 piece of pizza = x

Set up a proportion

24 students are given 24 pieces of pizza -- Cost 25.65

1 student 1 piece of pizza = x

Solution

24 / 1 = 25.65/x               Cross Multiply

24x = 1 * 25.65                Divide both sides by 24

24x/24 = 25.65/24

x  = 1.07 / slice.

Answer:

Step-by-step explanation:

The correct statements about the given triangle are : All sides have different lengths, The third angle measures 40°, It is an acute triangle.

A polygon with three vertices, angles and sides is called a triangle.

Given is a triangle with angle measures of 60° and 80°,

We need to choose the correct statement from the given options,

Calculating the 3rd angle, let its measure be x,

60° + 80° + x = 180°

x = 40°

Since, all the angles are different therefore, the sides will also be different,

Also, all the angles are less than 90°, therefore, the triangle is an acute triangle,

Hence, the correct statements about the given triangle are : All sides have different lengths, The third angle measures 40°, It is an acute triangle.

Alex's ride is $15.25

The equation to find this is

1.25m + 4 = cost

m = miles traveled

Function f(x), h(x), k(x) and t(x) will have real roots while function g(x) and p(x) will have imaginary roots.

Given quadratic functions are:

[tex]1) f(x)= x^{2} +6x+8\\2)g(x) = x^{2} +4x+8\\3)h(x) = x^{2} -12x+32\\4)k(x)=x^{2} +4x-1\\5)p(x)=5x^{2} +5x+4\\6)t(x) = x^{2} -2x-15[/tex]

The general form of a quadratic equation is:

[tex]ax^{2} +bx+c=0[/tex]

On comparing [tex]x^{2} +6x+8 =0[/tex] with the general form,

a=1, b=6, c=8

If discriminant D=b²-4ac is greater than zero, the quadratic equation will have two distinct real roots, if D is less than zero, roots will be imaginary.

So, discriminant D for f(x)=0 will be:

[tex]b^{2} -4ac[/tex] = [tex]6^{2} -4*1*8 = 4[/tex] i.e. greater than zero.

So, the quadratic function [tex]f(x) = x^{2} +6x+8[/tex] will have two real distinct

roots.

Similarly, h(x), k(x), and t(x) will have real roots since their discriminants are greater than zero.

Thus, Function f(x), h(x), k(x) and t(x) will have real roots while function g(x) and p(x) will have imaginary roots.

Step-by-step explanation:

First find the length of the two equal sides. Use Pythagoras.

c^2 = a^2 + b^2

c = ?

a = 7

b = 1/2 48 = 24

c^2 = 24^2 + 7^2

c^2 = 576 + 49

c^2 = 625                Take the square root of 625

√c^2 = √625

c = 25

Both of the equal sides = 25

p = 12 °

Step-by-step explanation:

p + ( p + 6 ) = p + 41

p = 11.6

p = 12 °

Answer:

∠2 = 41°

Step-by-step explanation:

This is because, all three interior angles in a triangle will have a sum of 180 degrees.

So given that we have two angles, 90 degrees(right angle) and 49 degrees, we can replace angle 2 as our unknown value(a variable) and make it equal to 180 degrees then solve for x;

49 + 90 + x = 180

139 + x = 180

-139        -139

x = 41°, ∠2 = 41°

Answer:

G is the true proportion in ∆ABC and ∆DEF

Answer:

G, 4/6 = x/7

Step-by-step explanation:

This is because the two pairs x/7 and 4/6, are corresponding to each other and are formatted in the right order.

First, we make the denominators of 1/4 and 3/8 the same as the LCM (= 8)

-> 1/4 = 1 x 2 / 4 x 2 = 2/8
-> 1 - ... = 2/8 + 3/8 = 5/8

The missing fraction = 1 - 5/8 = 3/8.
