a(2,3)b(7,3),and c(7,-2) are three verticed of square abcd. what are the coordinated of vertex d
Answers
Answer:
D (2,-2)
Step-by-step explanation:
The coordinates are the pair (x,y) in the axis. We already have three vertexs: a: (x,y)=(2,3); b:(x,y)= (7,3) and c: (x,y)=(7,-2).If you see the picture attached, where all points available are in pink, you will see that the distance between the sides that are already defined equals 5. Because all squares have equals sides, then we must find the missing side that will be at a distance of 5 between the other two vertexs.That point is d (x,y)=(2,-2).

Step-by-step explanation:
Let x be the smaller than 4 ×[tex]10^{-2}[/tex].
To find, the number of times smaller is 2 × [tex]10^{-3}[/tex] than 4 × [tex]10^{-2}[/tex] = ?
∴ x = [tex]\dfrac{4\times 10^{-2}}{2\times 10^{-3}}[/tex]
= 2 × [tex]10^{-2}[/tex] × [tex]10^{3}[/tex]
Using the identity,
[tex]a^{m}=\dfrac{1}{a^{-m}}[/tex]
= 2 × [tex]10^{-2+3}[/tex]
Using the identity,
[tex]a^{m} \timesa^{n}=a^{m+n}[/tex]
= 2 × [tex]10^{1}[/tex]
= 2 × 10
= 20
Thus, the required "option A) 20" is correct.

Answers
To add 471 and 582, line up the numbers by place value and add each column, carrying over as needed. The sum is 1053. You check by reversing the order of the numbers and adding again; the sum should remain the same.
Explanation:To add the following numbers and use the checking method (add down and then add up), perform the following steps:
Write down the numbers vertically aligned by their place values: 471 + 582 Add the ones place values (1+2) to get 3. Add the tens place values (7+8) to get 15, write down 5 and carry over 1. Add the hundreds place values (4+5) along with the carried over 1 to get 10, write down 0 and carry over 1. Write the carried over 1 in the next left column to get the final sum: 1053 To check, add the sum upwards: 582 + 471 You should arrive at the same sum: 1053.
If you obtain the same result by both adding down and adding up, your answer is verified as correct.

Answers
Answer:
The scale factor is 0.25.
Step-by-step explanation:
We have two side lengths.
First figure: A diamond with a side length of 5.8
This is the object length.
Second figure: Then a smaller diamond with a side length of 1.45
This is the image length.
The scale factor is
[tex]k = \frac{image \: length}{object \: length} [/tex]
[tex]k = \frac{1.45}{5.8} [/tex]
[tex]k = 0.25[/tex]

RS and ST are 2 sides of a regular 12-sided polygon.
RT is a diagonal of the polygon.
Work out the size of angle STR.
You must show your working.
Answers
Answer:
15°
Step-by-step explanation:
The exterior angle at vertex S is 360°/12 = 30°. That angle has a measure that is equal to the sum of the congruent angles at R and T of ΔRST. In other words, ...
∠T = 30°/2 = 15°
The size of angle STR is 15°.
The sides of a regular polygon are congruent.
The size of STR is 15 degrees
The polygon is 12-sided.
This means that:
[tex]\mathbf{n =12}[/tex]
The sum of angles in a regular hexagon is 360.
So, the angle at vertex S is:
[tex]\mathbf{\theta = \frac{360}{n}}[/tex]
This gives
[tex]\mathbf{\theta = \frac{360}{12}}[/tex]
[tex]\mathbf{\theta = 30^o}[/tex]
The external angle of a triangle equals the sum of the opposite internal angles.
This means that:
[tex]\mathbf{\theta = \angle STR + \angle SRT}[/tex]
Where:
[tex]\mathbf{ \angle STR = \angle SRT}[/tex]
So, we have:
[tex]\mathbf{\theta = \angle STR + \angle STR}[/tex]
[tex]\mathbf{\theta = 2\angle STR}[/tex]
Substitute [tex]\mathbf{\theta = 30^o}[/tex]
[tex]\mathbf{30^o = 2\angle STR}[/tex]
Divide both sides by 2
[tex]\mathbf{15^o = \angle STR}[/tex]
Rewrite as:
[tex]\mathbf{\angle STR = 15^o }[/tex]
Hence, the size of STR is 15 degrees

A regular pentagon is dilated by a scale factor of 73 to create a new pentagon. How does the perimeter of the new pentagon compare with the original perimeter?
Answers
Question:
A regular pentagon is dilated by a scale factor of 7/3 to create a new pentagon. How does the perimeter of the new pentagon compare with the original perimeter?
Answer:
The perimeter of the new pentagon is equal to [tex]\frac{7}{3}[/tex] times the perimeter of the original pentagon
Solution:
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let ,
z is the scale factor
x is the perimeter of the new pentagon
y is the perimeter of the original pentagon
Then,
Scale factor = ratio of perimeters
[tex]z=\frac{x}{y}[/tex]
In this problem we have
[tex]z=\frac{7}{3}[/tex]
Substituting we get,
[tex]\frac{7}{3} = \frac{x}{y}\\\\x = \frac{7}{3}y[/tex]
Which means,
[tex]perimeter\ of\ the\ new\ pentagon = \frac{7}{3} \times \text{ perimeter of the original pentagon}[/tex]
Therefore , the perimeter of the new pentagon is equal to [tex]\frac{7}{3}[/tex] times the perimeter of the original pentagon

What two numbers multiply to -27 and add to 1
Answers
Answer:
3 x 9, 1 x 27, 9 x 3
Step-by-step explanation:
you have to multiple 3 x 9 to get to 27. you have to multiple 1 x 27 to get 27. you have to multiple 9 x 3 to get 27.The two numbers that multiply to -27 and add to 1 are 9 and -3.
To find two numbers that multiply to -27 and add to 1, we can use the method of factoring and algebraic manipulation.
Let the two numbers be x and y.
Step 1: Set up the equations based on the given conditions:
xy = -27 (the two numbers multiply to -27)
x + y = 1 (the two numbers add to 1)
Step 2: Solve one of the equations for one variable in terms of the other.
From the second equation, we can express y in terms of x:
y = 1 - x
Step 3: Substitute the value of y into the first equation:
x(1 - x) = -27
Step 4: Expand and rearrange the equation:
x - x^2 = -27
Step 5: Rewrite the equation in standard quadratic form:
x^2 - x - 27 = 0
Step 6: Factor the quadratic equation:
(x - 9)(x + 3) = 0
Step 7: Set each factor equal to zero and solve for x:
x - 9 = 0 --> x = 9
x + 3 = 0 --> x = -3
So, the two numbers are 9 and -3, as 9 * -3 = -27, and 9 + (-3) = 1.
In conclusion, the two numbers that multiply to -27 and add to 1 are 9 and -3. By setting up and solving the system of equations and factoring the quadratic equation, we obtained these two values that satisfy the given conditions.

You can divide both sides by -3 in order to get:

-T.B.
To solve this, you need to isolate/get the variable "x" by itself in the equation:
-3(x + 5) = -9 Distribute/multiply -3 into (x + 5)
(-3)x + (-3)5 = -9
-3x - 15 = -9 Add 15 on both sides
-3x - 15 + 15 = -9 + 15
-3x = 6 Divide -3 on both sides to get "x" by itself
[tex]\frac{-3x}{-3} =\frac{6}{-3}[/tex]
x = -2
I just realized I took unnecessary steps....you could've just divided -3 then subtracted 5
-3(x + 5) = -9 Divide -3 on both sides [two negative signs cancel each other out and become positive]
x + 5 = 3 Subtract 5
x = -2
You start driving north for 7 miles, turn right, and drive east for another 24 miles. At the end of driving, what is your straight line distance from your starting point?
Answers
Answer:
[tex]AC = 25\ miles[/tex]
Step-by-step explanation:
Given:
Distance for north side = 7 miles.
Distance for east side = 24 miles.
We need to find the displacement.
Solution:
Figure shows Point A is starting point and AB = 7 miles is North side distance and BC = 24 miles is east side distance and AC is shown as displacement.
Using Pythagoras theorem to find displacement (AC).
[tex](AC)^{2}=(AB)^{2}+(BC)^{2}[/tex]
Substitute AB = 7 and BC = 24 in above equation.
[tex](AC)^{2}=(7)^{2}+(24)^{2}[/tex]
[tex](AC)^{2}=49+576[/tex]
[tex](AC)^{2}=625[/tex]
[tex]AC = \sqrt{625}[/tex]
[tex]AC = 25\ miles[/tex]
Therefore, displacement of the car [tex]AC = 25\ miles[/tex]

Answers
Answer:
2000 ml
Step-by-step explanation:
Given: Sarai pours all the liquid from a full small beaker into a larger beaker.
The liquid fills the large beaker to 15% of its capacity.
The small beaker holds 300 ml.
Lets assume capacity of large beaker to hold be "x".
As given, Sarai pours all the liquid from a full small beaker into a larger beaker
∴ [tex]15\% \times x= 300\ ml[/tex]
⇒ [tex]0.15x= 300[/tex]
Dividing both side by 0.15
⇒[tex]x= \frac{300}{0.15}[/tex]
∴ [tex]x= 2000\ ml[/tex]
Hence, the large beaker can hold 2000 ml of liquid.
