The true statements are,
⇒ If the price is marked up 25%, the selling price will be $50.
⇒ If the selling price is $70, the price is marked up 75%.
What is the Cost price?
Cost price is the total amount of money that it costs a manufacturer to produce a given product or provide a service.
Given that:-
A Store bought jeans at a cost of $40 a pair.
If the price is marked up 25%, the selling price will be $50
⇒ 40 x 25 / 100 = 10
Selling Price = $50
Hence, This is true statement.
And, If the selling price is $70, the price is marked up 75%.
P = 70 - 40 = $30
40 x 75 / 100 = $30
Hence, This statement is true.
Therefore, the true statements are;
⇒ If the price is marked up 25%, the selling price will be $50.
⇒ If the selling price is $70, the price is marked up 75%.

Triangle HOP has coordinates H (2, 1), O (-3, 4), and P (5, 7). Determine the coordinates of the
image of AHOP after each rotation.
a A rotation 90° clockwise about the origin
b) A rotation 90° counterclockwise about the origin
A rotation 180° about the origin
The image of ΔHOP with coordinates H(2,1), O(-3,4), and P(5,7).
(a) after 90° clockwise rotation is H'(1,-2,),O'(4,3),P'(7,-5) ,
(b) after 90° counterclockwise rotation is H''(-1,2),O''(-4,-3),P''(-7,5) ,
(c) after 180° rotation is H'''(-2,-1),O'''(3,-4),P'''(-5,-7) .
When a point (x,y) is rotated 90° in clockwise about the origin then the image after rotation becomes (y,-x) .
When a point (x,y) is rotated 90° in counterclockwise about the origin then the image after rotation becomes (-y,x) .
When a point (x,y) is rotated 180° about the origin then the image after rotation becomes (-x,-y) .
Part(a)
The ΔHOP with coordinates H(2, 1), O(-3, 4), and P(5, 7) is rotated 90° in clockwise direction ,
we know the points (x,y) becomes (y,-x),
So the image of ΔHOP after rotation becomes H' , O' , P' .
H(2, 1) → H'(1,-2)
O(-3, 4) → O'(4,3)
P(5,7) → P'(7,-5)
Part(b)
The ΔHOP with coordinates H(2, 1), O(-3, 4), and P(5, 7) is rotated 90° in counterclockwise direction ,
we know the points (x,y) becomes (-y,x),
So the image of ΔHOP after rotation becomes H'' , O'' , P'' .
H(2, 1) → H''(-1,2)
O(-3, 4) → O''(-4,-3)
P(5,7) → P''(-7,5)
Part(c)
The ΔHOP with coordinates H(2, 1), O(-3, 4), and P(5, 7) is rotated 180°,
we know the points (x,y) becomes (-x,-y),
So the image of ΔHOP after rotation becomes H''' , O''' , P''' .
H(2, 1) → H'''(-2,-1)
O(-3, 4) → O'''(3,-4)
P(5,7) → P'''(-5,-7)
Therefore , The image of ΔHOP
(a) after 90° clockwise rotation is H'(1,-2,),O'(4,3),P'(7,-5) ,
(b) after 90° counterclockwise rotation is H''(-1,2),O''(-4,-3),P''(-7,5) ,

Find the perimeter of ∠A B C to the nearest hundredth, given the coordinates of its vertices. A(-3,2), B(2,-9), C(0,-10)
The perimeter of the triangle ABC is approximately equal to 35.633 units.
How to determine the perimeter of a triangle
In this problem we find the locations of the three vertices of the triangle and from which we have to calculate the length of each of the three sides. The perimeter is the sum of the three lengths. First, determine the vectors of each side:
AB = (2, - 9) - (- 3, 2)
AB = (5, - 11)
BC = (0, - 10) - (2, - 9)
BC = (- 2, - 1)
AC = (0, - 10) - (- 3, 2)
AC = (3, - 12)
Second, calculate the magnitudes of the three sides:
AB = √[5² + (- 11)²]
AB = √146
BC = √[(- 2)² + (- 11)²]
BC = 5√5
AC = √[3² + (- 12)²]
AC = 3√17
Third, add the three lengths to find the perimeter:
p = √146 + 5√5 + 3√17
p ≈ 35.633
Remark
The statement reports a typing mistake that it would take a triangle for an angle, which is absurd since angles only have one vertex. Correct statement is shown below:
Find the perimeter of Δ ABC to the nearest hundred, given the coordinates of its vertices A(x, y) = (- 3, 2), B(x, y) = (2, - 9) and C(x, y) = (0, - 10).

gabriela is building a brick wall. each row of bricks is 6.5\,\text{cm}6.5cm6, point, 5, start text, c, m, end text tall except that the top row is 1\,\text{cm}1cm1, start text, c, m, end text shorter because it has no mortar. she wants the wall to be 259\,\text{cm}259cm259, start text, c, m, end text tall.
The equation is 6.5 (r-1) + 5.5 = 259 or 6.5 r - 1 = 259.
In this case, r stands for the overall number of rows.
The answer indicates that each row is 6.5 cm tall.
What is an equation?A formula known as an equation uses the equals sign (=) to express how two expressions are equal. The word "equation" and its cognates in other languages may have slightly different meanings. For instance, in French, an equation is defined as having one or more variables, while in English, any well-formed formula consisting of two expressions related with an equals sign is an equation. The task of solving an equation with variables entails figuring out which values of the variables cause the equality to hold true. The unknown variables are also known as the variables for which the equation must be solved, and the unknown variable values that fulfill the equality are known as the equation's solutions. Identity equations and conditional equations are the two types of equations.
The height of the top row is 6.5 - 1 = 5.5 cm.
Except for this row, there are total rows of = (r-1)
So, 6.5 is the total length of these rows (r-1)
The overall length of the wall is therefore equal to the sum of the (r-1) row and the top row.
However, once more in line with the inquiry,
Exactly 259 centimeters must be on the wall.
⇒ 259 = 6.5(r-1) + 5.5
⇒ 6.5(r-1) + 5.5 = 259
⇒ 6.5 r - 6.5 + 5.5 = 259
⇒ 6.5 r - 1 = 259
Which is the required equation for finding the number of rows (r).

On day four, she collected 13 cans. If Carrie wanted to give at least 100 cans of food to the shelter and this pattern of can collecting continued, did she meet her goal?
The number of can collected by Carrie after one week if the pattern continued will be; 105 cans and hence, she met her goal.
How many cans were collected by Carrie and dis she meet her goal?It follows from the task content that Carrie's target for can collection was 100 units of can collected over 1 week.
Since, one week contains seven, 7 days, it follows that she has 7 days to meet her target.
Following from observation, she increased the number of cans collected each day following a pattern; 7, 8, 10, 13.... where the difference between two successive days increases by 1 each time.
Hence, the number of cans collected for the rest of the days are as follows;
Day 5 = 13 + 4 = 17Day 6 = 17 + 5 = 22Day 7 = 22 + 6 = 28Therefore, the total number of cans collected is; 7 + 8 + 10 +13 + 17 + 22 + 28 = 105 cans and hence, she meets her goal.

Two angles of a triangle have measures 45⁰ and 92⁰ . What type of triangle is it?
a. obtuse scalene
b. obtuse isosceles
c. acute scalene
d. acute isosceles
A triangle with two angles measuring 45⁰ and 92⁰ is an obtuse scalene triangle. The answer is A.
A triangle is a two-dimensional shape that has three sides and three angles. The sum of its interior angles is 180⁰.
If two angles of a triangle have measures 45⁰ and 92⁰, solving for the third angle
180⁰ = 45⁰ + 92⁰ + third angle
third angle = 43⁰
If a triangle has an angle greater than 90⁰, then it is an obtuse triangle.
If a triangle has angles less than 90⁰, then it is an acute triangle.
If a triangle has an angle equal to 90⁰, then it is a right triangle.
An isosceles triangle is a triangle with two congruent sides and congruent base angles (2 angles are equal).
An equilateral triangle is a triangle with all three sides equal and all three angles are of equal measures.
A scalene triangle is a triangle with no sides are equal and no angle are equal also.
Since our triangle has 3 unique angles: 43⁰, 45⁰, and 92⁰, with one angle greater than 90⁰, then it is an obtuse scalene triangle.

Height of a rhombus is [tex]20 m[/tex]
We know that,
Area of rhombus = base × height

The average rate of change over the entire slide if the height of the slide is 2 feet is; -3.9
What is the average rate of change?
Average rate of change is defined as a measure of how much the function changed per unit, on average, over that interval.
First, we will calculate the average rate from x = 0 to x = 15:
We have:
R = ((80 - 10)/(0 - 15))
R = -4.667
Let us now calculate average rate of change for the entire interval supposing that the height of the slide is 2 feet,:
From x = 0 to x = 20, we have;
