The coordinates of a triangle are A(4,5) B(-1,4) C(2,-3)
after a translation of up 3 minus 4 what would be the new coordinates

Answers

After translation of up 3 and bottom 4, all the x-coordinates will increase by 3, and all the y-coordinates will decrease by 4.

Coordinates would be: A(4+3,5-4), B(-1+3,4-4), C(2+3,-3-4)
So, Final answer would be: A(7,1) B(2,0) C(5,-7)

Hope this helps!
A (0,8)
B (-5,7)
C (-2,0)

What is the diameter and radius of a circle with an 18 inch circumference?

Answers

The approximate diameter of the circle is 5.73 inches, and the approximate radius is 2.86 inches.

What is the diameter and radius of a circle with an 18 inch circumference?

To discover the diameter and radius of a circle with a given circumference, ready to utilize the taking after equations:

Circumference = π * Diameter

Diameter = Circumference / π

Given that the circumference of the circle is 18 inches, able to calculate the diameter as follows:

Diameter = 18 inches / π

To discover the radius, we will utilize the equation:

Radius = Diameter / 2

Let's calculate the values:

Diameter = 18 inches / π ≈ 5.73 inches

Radius = 5.73 inches / 2 ≈ 2.86 inches

Hence,  the approximate diameter of the circle is 5.73 inches, and the approximate span is 2.86 inches.

Write a real world problem that correspond to the equation 10x + 30 =100?

Answers

10x + 30 = 100

Here is a real world problem to demonstrate this. 

Mack decides to burn some calories, so he attends a gym. A cost of a gym costs 10 dollars per month, with an addition registration fee of 30 dollars. Mack has spent 100 dollars on the gym so far. How many months has he been participating at the gym? 

Let 'x' represent the amount of months spent. 

Saturday night after the marshmallows ran out, the counselor
threw 30 cold stones on the campfire, and sent the campers
to bed in their tents.

But several campers noticed that there were still live coals in
the fire.  This was a tent situation, and they knew that they
should not leave until it's completely out.  So they each
picked up 10 cold stones and they all threw those on the fire
too.  Then the fire was really out, so they all went to their tents.

In the morning the same campers who threw 10 stones apiece
onto the fire all got together and went to look at it.  It was definitely
stone cold, so they spread it out and counted all the stones in it.
They found that there were exactly 100 stones. How many
campers threw stones on the fire after the counselor left ?

How do you think inequalities are different from equations you have worked with before?

Answers

Answer:

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

Hope this helps, and have a nice day

Step-by-step explanation:

Good luck! :)

Answer:yes they are different

Step-by-step explanation:

1. An equation is an equality of two mathematical expressions. That's why it has an equal(=) sign . For example:

12x=10x +2x

Or

3x+4y=5

2. While an inequation is an inequality of two expressions and here the greater than and lower than signs are used with equal sign i.e. >,< or=

For example

4y+5a > 5

Or

8a< 7b

Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the length of its side, s?

Answers

Using the Pythagorean Theorem, the length of a square diagonal, in function of it's sides s, is given by:

d = s√(2)

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

In a square, as given in the figure below, the legs are the sides s, of equal measure, while the hypotenuse is the diagonal d, thus:

d^2 = s^2 + s^2

d^2 = 2s^2

d = √(2s^2)

d = s√(2)

A similar problem is given at brainly.com/question/21691542
the square's diagonal is the triangle's hypotenuse.

the original Pythagorean theorem is  a^(2) + b^(2) = c^(2)   where a and b are the two sides and c is the hypotenuse.

that means the Pythagorean theorem for this question is:

s^(2) + s^(2) = d^(2)  or 2( s^(2) )= d^(2)

A square with sides of length 5 is positioned inside a square with sides of length 7. What isthe total area between the squares?​

Answers

Answer: 24cm²

Step-by-step explanation:

Let square with length 5cm be represented with A, and square with 7cm be represented with B.

Area of a square is L²

Square A will have an area of 5² = 25cm²

Square B will have an area of 7² = 49cm²

Total area between the two squares will be = Area of Square (B - A)

i.e.

Total Area = 49cm² - 25cm² = 24cm²
