An ordered pair is a composite of the x coordinate (abscissa) and the y coordinate (ordinate), with two values expressed between parenthesis in a predetermined order. It aids visual comprehension by locating a point on the Cartesian plane. An ordered pair’s numeric values can be integers or fractions.
The origin is the place where both axes cross. Every point on the coordinate plane is represented by an ordered pair (x, y), with the first element x referred to as the x-coordinate and the second element y referred to as the y-coordinate.

which choice is a correct congruence statement for the triangles?
The reason why is because the order is important when it comes to congruent statements. I'm referring to the order of the letters of ACB and CAD.
Each answer choice has "ACB" in that exact order shown on the left hand side of each congruent statement. We have "A" listed first, then "C" next. In short, segment AC is the first thing mentioned of ACB. This means that we need to list out segment AC as the first thing for the other triangle as well, in order to have a match. Segment AC is the same as segment CA, which is the first segment mentioned in triangle CAD. That's why choice 3 is the answer.
Note how something like triangle CDA won't work since segment CD is listed first, which doesn't pair up with segment AC. This allows us to rule out the first answer choice. Choices 2 and 4 can be eliminated for similar reasons.
Put another way: let's assume choice 1 was the answer. That would mean that AC = CD as they are the first pair of letters of ACB and CDA respectively. But the diagram shows that AC = CD is not true; otherwise, the segments would have similar tickmarks to show they are the same length. This is an alternative way to see why choices 1, 2, and 4 can be crossed off the list.

A)
QRST ∼ EFGH
B)
QRST ∼ FEHG
C)
Impossible to determine.
D)
The quadrilaterals are not similar.
Answer:
D) The quadrilaterals are not similar
Step-by-step explanation:
The given parameters are;
In quadrilateral EFGH, the sides are;
[tex]\overline {EF}[/tex] = [tex]\overline {HG}[/tex] = 8, [tex]\overline {EH}[/tex] = [tex]\overline {FG}[/tex] = 7
In quadrilateral QRST, the sides are;
[tex]\overline {QR}[/tex] = [tex]\overline {ST}[/tex] = 32, [tex]\overline {QT}[/tex] = [tex]\overline {RS}[/tex] = 36
The ratio of the lengths of the corresponding parallel sides on quadrilaterals EFGH and QRST are;
For the horizontal sides, we have;
[tex]\overline {EF}[/tex]/[tex]\overline {QR}[/tex] = 8/32 = 1/4 = 0.25
For the inclined parallel sides, we have;
[tex]\overline {EH}[/tex]/[tex]\overline {QT}[/tex] = 7/36 = 0.19[tex]\overline 4[/tex]
Therefore, given that the ratio of the corresponding sides on quadrilaterals EFGH and QRST are not equal, we have;
The quadrilaterals (EFGH and QRST) are not similar.

The decimal form of the -1 1/12 is obtained by finding the sum of -1 and -1/12 (-1/12 = -0.08[tex]\overline{3}[/tex] a recurring decimal), which is the option A
A. -1.08[tex]\overline{3}[/tex]
What is a recurring decimal?A recurring decimal is a decimal that has a digit or a group of digits that is continuously repeated in the decimal.
The specified expression, -1 1/12, can be presented as follows;
[tex]-1\dfrac{1}{12}[/tex]
The value of the specified expression in decimal form is therefore;
[tex]-1\dfrac{1}{12}= -1+\left( - \dfrac{1}{12}\right)[/tex]
[tex]- \dfrac{1}{12} = -0.08\overline{3}[/tex]
The fraction -1/12, therefore consist of a recurring decimal, with the 3 in the thousandth place after the 8 being the part that repeats.
Therefore, the value of the expression, [tex]-1+\left( - \dfrac{1}{12}\right)[/tex] is -1 + (-0.08[tex]\overline{3}[/tex])
-1 + (-0.08[tex]\overline{3}[/tex]) = -1.08[tex]\overline{3}[/tex]
The specified expression is therefore;
[tex]-1\dfrac{1}{12}[/tex] = -1 + (-0.08[tex]\overline{3}[/tex]) = -1.08[tex]\overline{3}[/tex]

Answer:
x=6.3m
Step-by-step explanation:
Let the opposite side be y in 2nd triangle.
tan 27° = y/9
=> tan 27° X 9 = y
∴ y = 4.585m ≈ 4.59m
cos 43° = y/x
=> cos 43° = 4.59/x
=> cos 43° X x= 4.59
=> x = 4.59/cos 43°
∴ x = 6.276m ≈ 6.3m (corrected to 1 dp)

So tripple of a number added to its half part its equal to the difference between four times the number and 12
3x+x/2=4x-12
6x+x=2(4x-12)
Apply distributive property on RHS
7x=8x-24
Subtract 7x on both sides and add 24
24=x
Hence, if triple of a number added to its half part its equal to the difference between four times the number and 12 then the number is 24.

Because milk tea is flourishing in their town, Mathilda decided to sell Wintermelon milk tea (WMT) powder at Php 1 per gram and Okinawa milk tea (OMT) powder at Php 2 per gram. To increase her profit, she plans to mix the two milk tea powders. How much OMT should she mix with 300 grams of WMT so that she can sell the resulting mixture at Php 1.80 per gram?
So, Mathilda should mix 600 grams of OMT with 300 grams of WMT to sell the resulting mixture at Php 1.80 per gram.
Define the unitary method.The unitary approach involves calculating the value of a single unit, from which we may calculate the values of the necessary number of units.
The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.
What is a unit?A unit is a quantity with a fixed magnitude that is used to gauge the sizes of other quantities that behave similarly.
The terms millimeter (mm), centimeter (cm), meter (m), and kilometer (km) are used to describe length (km). The weight is measured in kilograms (kg) and grams (g). Milliliter (ml) and liter are used to measure volume (L).
Let x be the amount of OMT powder in grams. We know that the total amount of powder in the mixture is x + 300 grams since Mathilda is mixing x grams of OMT with 300 grams of WMT.
(x * Php 2 + 300 * Php 1) / (x + 300) = Php 1.80
Solving for x, we can get the amount of OMT powder in grams:
x = (300 * Php 1.80 - 300 * Php 1) / (Php 2 - Php 1.80) = 300 * (Php 1.80 - Php 1) / (Php 2 - Php 1.80) = 600

The range of solutions for the given inequality is -5<y<5.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -6<1/3(6y + 12)<14.
Here, -6<(2y + 4)<14
-6<(2y + 4)
Subtract 4 on both the sides of an inequality, we get
-10<2y
Divide 2 on both the sides of an inequality, we get
-5<y
(2y + 4)<14
Subtract 4 on both the sides of an inequality, we get
2y<10
Divide 2 on both the sides of an inequality, we get

On solving the provided question, we can say that Surface Area of central park = 2.5 × 0.5 = 1.25 square mile
what is surface area ?An indication of the overall space occupied by an object's surface is its surface area. A three-dimensional shape's surface area is the total amount of space that surrounds it. A three-dimensional shape's entire surface area is known as its surface area. The surface area of a cuboid with six rectangular faces may be calculated by adding the areas of each face. As an alternative, you may use the formula below and name the box's dimensions as follows: Surface (SA) = 2lh + 2lw + 2hw. Surface area is a measurement of the entire amount of space filled by a three-dimensional shape's surface (a three-dimensional shape is a shape that has height, width, and depth).
Surface Area of central park = 2.5 × 0.5 = 1.25 square mile
1 acre = 1/640 square mile
