Step-by-step explanation:

Answer:

its 6 7/8

Step-by-step explanation:

Answer:

The coordinates of the point are (-4.5,-1).

Step-by-step explanation:

We want to find point T(x,y).

I am going to say that out points are A(-8,-2) and B(6,2)

Since it partitions the segment in a 1:3 ratio, we have that:.

[tex]T - A = \frac{1}{1+3}(B-A)[/tex]

[tex]T - A = \frac{1}{4}(B-A)[/tex]

We apply this to both the x-coordinate and y-coordinate of T.

x-coordinate:

x-coordinate of A: -8

x-coordinate of B: 6

x-coordinate of T: x.

So

[tex]T - A = \frac{1}{4}(B-A)[/tex]

[tex]x - (-8) = \frac{1}{4}(6-(-8))[/tex]

[tex]x + 8 = \frac{14}{4}[/tex]

[tex]x = \frac{14}{4} - 8[/tex]

[tex]x = \frac{14}{4} - \frac{32}{4}[/tex]

[tex]x = -\frac{18}{4}[/tex]

[tex]x = -4.5[/tex]

y-coordinate:

y-coordinate of A: -2

y-coordinate of B: 2

y-coordinate of T: y.

[tex]T - A = \frac{1}{4}(B-A)[/tex]

[tex]y - (-2) = \frac{1}{4}(2-(-2))[/tex]

[tex]y + 2 = 1[/tex]

[tex]y = -1[/tex]

The coordinates of the point are (-4.5,-1).

Answer:

2h-2=92 and h-2=92-h.

Step-by-step explanation:

Hannah, h, is the older sibling and their ages are consecutive odd integers. This means that Anthony's age will be 2 less than Hannah's, or h-2.

The sum of these would be h+(h-2), giving us the equation h+(h-2)=92.

Combining like terms we would have the first correct choice, 2h-2=92.

Our first equation can be transformed, however, to have (h-2) by itself. To do this, we would subtract h from both sides, giving us h-2=92-h.

The equation that will represent the sum of the age of Hannah and Anthony will be 2x+2=92.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the age of Hannah be x. and Since the age of Hannah and Anthony are two consecutive odd integers, therefore, the age of Anthony will be (x+2).

As it is given that the sum of the ages of the two other person is 92, therefore, the equation that will represent the sum of the age of the two persons can be written as,

[tex]x+(x+2)=92\\\\x+x+2=92\\\\2x+2=92[/tex]

Thus, the equation that will represent the sum of the age of Hannah and Anthony will be 2x+2=92.

9.9 m

Step-by-step explanation:

According to the scale the person is 2 cm tall, and the tree is 12 cm tall.

So we know that the tree is 6 times taller than the person because,

12 cm = 6 x 2 cm

The actual height of the person is 1.65 m.

Since we know that the tree is 6 times taller than the person, we can find the height of the tree to be

6 x 1.65 m = 9.9 m

Answer:

  110 square inches

Step-by-step explanation:

First, recall the formula for the area of a trapezoid:

  A = (1/2)(b1 +b2)h

Next, identify the base and height dimensions on the figure.

  b1 = 13 in; b2 = 9 in; h = 10 in

Next, fill the numbers into the formula and do the arithmetic.

  A = (1/2)(13 in + 9 in)(10 in) = (1/2)(22 in)(10 in) = 110 in^2

Last, answer the question asked.

  The area of the trapezoid is 110 square inches.

Answer:

The midpoint is (3, 3).

Step-by-step explanation:

We are given the two points A(9, 11) and B(-3, -5).

The midpoint is given by:

[tex]\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)[/tex]

So:

[tex]\displaystyle M = \Big( \frac{9+(-3) }{2}, \frac{ 11+(-5) }{2} \Big) = (3,3)[/tex]

The midpoint is (3, 3).

We want to show that AM = MB.

We can use the distance formula:

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

The distance between A(9, 11) and M(3, 3) will then be:

[tex]AM=\sqrt{(9-3)^2+(11-3)^2}=\sqrt{6^2+8^2}=\sqrt{100}=10[/tex]

And the distance between B(-3, -5) and M(3, 3) will be:

[tex]MB = \sqrt{ (3-(-3))^2 + (3-(-5))^2 } = \sqrt{(6)^2+(8)^2} = \sqrt{ 100 } = 10[/tex]

So, AM = MB = 10.

Since AM = MB = 10, AM + MB = 10 + 10 = 20.

So, we want to prove that AB = 20.

By the distance formula:

[tex]AB=\sqrt{(9-(-3))^2+(11-(-5))^2}=\sqrt{12^2+16^2}}=\sqrt{400}=20\stackrel{\checkmark}{=}20[/tex]
