Geometric shapes are mathematical shapes that include squares and triangles

The side lengths of a square are congruent, and the adjacent sides are perpendicular.

So, we start by calculating the side lengths using the following distance formula

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

Using the above formula, we have:

[tex]AB = \sqrt{(3-2)^2 + (4+2)^2} = \sqrt{37[/tex]

[tex]BC = \sqrt{(2+4)^2 + (-2+1)^2} = \sqrt{37[/tex]

[tex]CD = \sqrt{(-4+3)^2 + (-1-5)^2} = \sqrt{37}[/tex]

[tex]DA = \sqrt{(-3-3)^2 + (5-4)^2} = \sqrt{37}[/tex]

The above shows that the side lengths of the square are congruent.

Next, calculate the slope of the sides using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m_{AB} = \frac{4 +2}{3 -2} = 6[/tex]

[tex]m_{BC} = \frac{-2 + 1}{2+4} = -\frac 16[/tex]

[tex]m_{CD} = \frac{-1 -5}{-4+3} = 6[/tex]

[tex]m_{DA} = \frac{5 -4}{-3-3} = -\frac 16[/tex]

Notice that the opposite slopes are congruent, and the adjacent slopes are opposite reciprocal.

The above highlight, and the equal side lengths show that the figure (1) is a square

The legs of a right isosceles triangle are congruent, and the legs are perpendicular.

So, we start by calculating the lengths of the legs using the following distance formula

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

Using the above formula, we have:

[tex]XY = \sqrt{(5-4)^2 + (-1-4)^2} = \sqrt{26[/tex]

[tex]XZ = \sqrt{(5-0)^2 + (-1+2)^2} = \sqrt{26[/tex]

The above shows that the legs of the right isosceles triangle are congruent.

Next, calculate the slope of the legs using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m_{XY} = \frac{5-4}{-1 -4} = -\frac{1}{5}[/tex]

[tex]m_{XZ} = \frac{5-0}{-1+2} = 5[/tex]

Notice that the slopes are opposite reciprocal.

The above highlight, and the equal legs show that the figure (2) is a right isosceles triangle

Answer:

It is 45 degree angle

Step-by-step explanation:

AB is the tilted angle of the triangle

BC is the height and the vertical part of the triangle

If AB is 10 then BC is 5 and AC is possibly about 6-8

If that is so then 2 right triangles is a square

A square has 90 degree angles on any angle

Divide 90 by 2 which is 45 because a right triangle is half of a square

Therefore angle ABC is 45 degrees

Solution:

Step-1: Find the volume of the rectangular prism.

Step-2: Find the volume of the small cube.

Step-3: Divide.

Thus, 560 cubes are needed to fill the rectangular prism.

Step-by-step explanation:

remember, that a/a = 1, and this is always the "whole" in such fraction scenarios.

in our case here : 9/9 or 3/3.

4 books for 2/9 of his money.

8 books for then 2× 2/9 = 4/9 of his money.

that is together

12 books for 6/9 = 2/3 of his money.

that leaves 3/9 = 1/3 of his money for the 2 identical bags.

so, 1/3 of his money for 2 bags.

how many bags for the whole (3/3) money ?

1/3 × x = 3/3

x = 3

he could have bought 3×2 = 6 bags with the original sum of money.

Step-by-step explanation:

You see this by looking at the outside and the answer is 4 by 3

Ok so, 42 ft. by 42 ft.

$25 per square yard

1 square yard = 9 square feet

The total square footage is 1,764 ft.

Total square yards is 196.

The total cost would be $4,900.

Answer:

b = 5

Step-by-step explanation:

Area of the triangle = b * 12/2 = 6b

Area of the rectangle = 9 * 12 = 108

Total area = 6b + 108  = 138

6b = 138 - 108 = 30

so b = 30/6 = 5

Hi! Hope you are having a nice day!

We are given the slope of the line and its y-intercept.

So, let's find the equation.

The y-intercept is written in the form (0, b).

No worries! b is the y-intercept.

Thus, the y-intercept equals 3.

Now, let's find the equation of the line with a slope of 4 and a y-intercept of 3.

We can write the equation in Slope-intercept form:

y=mx+b, where m stands for the slope and b stands for the y-intercept.

Since we have both m and b, we can just plug the given values:

y=4x+3 ✓

Hope you could understand everything.

Answer:

Let ABC be a triangle such that CA is produced to meet at E.

We know, an exterior angle of a Triangle is equal to non- adjacent interior angle, so

8x - 10 = x + 15 + 2x + 20

or, 8x - 3x = 35 + 10

or, 5x = 45

or, x = 9

Answer:

87

Step-by-step explanation:

First method:

- Open Excel and enter 360, 353 and 346 in column A (below each other)

- Select all 3 cells and drag the bottom-right square down to row 40.

Second method:

- Use the equation t(n) = 360-7(n-1)

- Solve for n=40

- t(40) = 360 - 7*39 = 87

The conditions for inference is not met in the question due to the fact that the large count condition is not met.

This is the condition in statistics that states that the numbers of the successes and the failures have to be greater than 10 for there to be a normal distribution.

Using this formula n(1-p) ≥ 10. The probabilioty is 95%, therefore it would be less than 10

Answer:

because it's an odd exponent

Step-by-step explanation:

-2^3 = -(2*2*2)

(-2)^3 = (-2)*(-2)*(-2)

if it was ^4 the sign would be flipped:

-2^4 = -(2*2*2*2) = -16

(-2)^4 = (-2)*(-2)*(-2)*(-2) = 16

The way to put this is that any negative base raised to an odd-numbered power, will result in a negative result, whereas any negative base raised to an even-numbered power, will result in a positive result, with the EXCEPTION of a negative base written WITHOUT grouping symbols. For instanse:

[tex]\displaystyle -1000 = -10^3 \\ -1000 = [-10]^3 \\ \\ BUT \\ \\ 10000 ≠ -10^4\:[-10000 = -10^4] \\ 10000 = [-10]^4[/tex]
