Answer:

1.46943231441048

Step-by-step explanation:

This a question about perimeter and equation, let's see how to solve that:

The perimeter of a rectangle is the sum of its 4 sides. In this case, we know that the perimeter is 118. We can do an equation with these datas:

[tex]\boxed{AB + BC + CD + DA = 118}[/tex]

We also know other informations: the side AB is equal to [tex]4y+3[/tex] and de side BC is equal to 3y. In a recltangle, parallels sides have the same value. So, the side CD is equal to [tex]4y+3[/tex] and the side DA is equal to 3y.

Now, we have these datas:

[tex]AB + BC + CD + DA = 118\\\\AB = CD = 4y + 3\\BC = DA = 3y[/tex]

Let's do and solve an equation:

[tex]AB + BC + CD + DA = 118\\\\4y+3 + 3y + 4y+3 + 3y = 118\\14y + 6 = 118\\14y = 118 - 6\\14y = 112\\y = \frac{112}{14} \\y = 8[/tex]

So, the value of y is 8. Let's replace the value of y in the side AB:

[tex]4y + 3\\4\times 8 + 3 = 35[/tex]

Therefore, the length of side AB is 35.

[tex]6^{10} = 6*6*6*6*6*6*6*6*6*6[/tex]

6 multiplied by itself 10 times is equal to:

60,466,176

[tex]6^4=6*6*6*6[/tex]

6 multiplied by itself 4 times is equal to:

1,296

[tex]60,466,176/1,294 = 46728.11[/tex]

Answer:

123 ft

Step-by-step explanation:

create a right angle triangle from the given info.

your perpedicular will be tree height and hypotneus will be 145 feet

sin 45=Tree height/145

122.96=tree height

123 ft

The height of the tree will be equal to 123 feet.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that a zip line from the tallest tree in the forest to the campsite is 145 feet. The angle of elevation from the ground to the top of the tree is 58°.

Create a right-angle triangle from the given info. your perpendicular will be tree height and your hypotenuse will be 145 feet

sin 45=Tree height/145

122.96=tree height

123 ft

The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.

Answer:-10

Step-by-step

900-800 over 0-10

100/-10

Answer:

The answer is (2, -1)

Step-by-step explanation:

The area of the circle is:

A = r²π

We know

A = 78.5

π = 3.14

78.5 = r² * 3.14

r² = 78.5 : 3.15

r² = 25

r = √25 = 5

The standard form equation of a circle is:

(x - h)² + (y - k)² = r²

We have:

(2, 4)

⇒ h = 2

   k = 4

r = 5

(x - h)² + (y - k)² = r²

(x - 2)² + (y - 4)² = 5²

(x - 2)² + (y - 4)² = 25

Now, let's substitute all choices:

(-6, 4):

(-6 - 2)² + (2 - 4)² = 25

(-8)² + (-2)² = 25

64 + 4 = 25

68 = 25

Wrong

(2, -1)

(2 - 2)² + (-1 -4)² = 25

0² + (-5)² = 25

0 + 25 = 25

25 = 25

Right

Step-by-step explanation:

148 and 7x+15 are alternate interior angles and alternate interior angles are equal when the lines are parallel

148 = 7x+15

Subtract 15 from each side

148-15 = 7x+15-15

133 =7x

Divide each side by 7

133/7 =7x/7

Option (4)

Step-by-step explanation:

Length of segment between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

From the figure attached,

Distance between A(0, -3) and B(3, 0) = [tex]\sqrt{(3-0)^2+(0+3)^2}[/tex]

AB = [tex]3\sqrt{2}[/tex]

Distance between A'(-3.5, -4.5) and B'(-8, 0)

Length of A'B' = [tex]\sqrt{(-3.5+8)^2+(-4.5-0)^2}[/tex]

A'B' = [tex]4.5\sqrt{2}[/tex]

Scale factor for dilation = [tex]\frac{4.5\sqrt{2}}{3\sqrt{2}}=1.5[/tex]

Therefore series of transformations will be,

A dilation of figure 1 with scale factor of [tex]\frac{3}{2}[/tex] and then a reflection.

Option (4) will be the answer.

Answer: Tom is incorrect.

Step-by-step explanation: Congruent is defined as having exactly the same angle measurements and exactly the same side lengths.

In the 1/3 dilation, the angles will remain the same, but all the sides will be shorter, 1/3 the lengths of the original image. The image and pre-image are not congruent. They are similar.
