Answer:
RJ and his 2 brothers are given a weekly allowance of PHP 2,000. They have allocated 60% for food, 8% for fare, 15% for school needs, and 17% for savings.
For food, the allocation would be: PHP 2,000 x 60% = PHP 1,200.
For fare, the allocation would be: PHP 2,000 x 8% = PHP 160.
For school needs, the allocation would be: PHP 2,000 x 15% = PHP 300.
For savings, the allocation would be: PHP 2,000 x 17% = PHP 340.
So, for food, the allocation is PHP 1,200, for fare, it's PHP 160, for school needs, it's PHP 300, and for savings, it's PHP 340

What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.For the angle A, we have that:
The opposite side is of 13.The hypotenuse is of 15.Applying the sine ratio, the angle measure is given as follows:
sin(A) = 13/15
A = arcsin(13/15)
A = 60º.

Julie plans to invest her bonus of P100, 000.00 in two banks. The first bank earns an interest of 6% per annum while the other bank earns 8% interest per annum. If she wants her investment to earn a total interest of exactly P7, 200.00 after a year, how much does she need ot invest in each bank?
The amount of money that is invested in the first and second accounts will be 40,000 and 60,000, respectively.
What is the solution to the equation?The possible value of the variables that satisfy the equation which is known as the solution of the equation.
The interest is given as,
I = PRT / 100
Let 'x' be the amount invested in the first bank. Then the amount of investment in the second bank is (100,000 - x). Then the equation is given as,
x · 0.06 · 1 + (100,000 - x) · 0.08 · 1 = 7,200
0.06x + 8,000 - 0.08x = 7,200
-0.02x = -800
x = 40,000
The amount in the second bank is given as,

Line AB contains points A(4, 5) and B(9, 7). What is the slope of AB?
Answer:
Step-by-step explanation:
The slope of a line can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are the coordinates of two points on the line. In this case, we can use points A(4, 5) and B(9, 7):
slope = (7 - 5) / (9 - 4) = 2 / 5
So, the slope of line AB is 2/5.

Point R is located at (1,1) on the coordinate plane. Point R is reflected over the y-axis to create point R ′ . Point R' is then reflected over the x-axis to create point R''. What ordered pair describes the location of R''?
Answer:
Step-by-step explanation:
Here's a step-by-step explanation of the reflections:
Point R is located at (1, 1) on the coordinate plane.
Reflection over the y-axis: This reflection changes the sign of the x-coordinate. In other words, if the point (x, y) is reflected over the y-axis, the reflected point will be ( -x, y). So, for point R at (1, 1), the reflection over the y-axis creates R' at (-1, 1).
Reflection over the x-axis: This reflection changes the sign of the y-coordinate. In other words, if the point (x, y) is reflected over the x-axis, the reflected point will be (x, -y). So, for point R' at (-1, 1), the reflection over the x-axis creates R'' at (-1, -1).
So the final location of R'' is at the ordered pair (-1, -1).

A survey was conducted in which the customer service representatives of two companies were rated on a scale of 1 to 6. The graph below shows customer service ratings of 20 representatives. The interquartile range for each company is 3. The difference between the median rating for each company is approximately how many times the interquartile range?
The difference between the median rating for each company is approximately 0.3 times the interquartile range.
How to calculate the median service rating?Generally speaking, the median for 20 observations is the average of the 10th and 11th number:
Median rating of Company A = (4 + 4)/2
Median rating of Company A = 8/2
Median rating of Company A = 4.
Median rating of Company B = (3 + 3)/2
Median rating of Company B = 6/2
Median rating of Company B = 3.
Difference in median = 4 - 3
Difference in median = 1
For the required expression that models the difference between the median rating for each company and the interquartile range, we have the following:

examine whether you can construct a triangle PQR such that QR=3 cm, PQ=6 cm, PR=3 cm. Justify your answer
No, it is impossible to construct a triangle PQR such that QR=3 cm, PQ=6 cm, PR=3 cm as the dimensions defy the triangle inequality theorem.
What is the triangle inequality theorem?It follows from the triangle inequality theorem that the sum of any two side lengths of a triangle must be greater than the third side length and also, the difference of two side lengths of a triangle must be less than the third side lengths.
However, in this case, since QR + PR = PQ, it can be inferred that the two side lengths cannot possibly be used to construct a triangle.

What is a rhombus?A rhombus is a quadrilateral that has four congruent sides.
The specified shape of the quadrilateral MATH = A rhombus
The coordinates of the endpoints of the diagonal [tex]\overline{MT}[/tex] of the rhombus are;
M(0, -1), and T(4, 6)The equation of the line that contains the diagonal [tex]\overline{AH}[/tex] of the rhombus can be found as follows;
The diagonals of a rhombus are perpendicular, therefore, the slope of the diagonal, [tex]\overline{AH}[/tex]is -1 divided by the slope of the diagonal [tex]\overline{MT}[/tex]
The slope of [tex]\overline{MT}[/tex] = (6 - (-1))/(4 - 0) = 7/4
The slope of [tex]\overline{AH}[/tex] = -1/(7/4) = -4/7
The diagonals of a rhombus bisect each other, therefore, the diagonals [tex]\overline{MT}[/tex] and [tex]\overline{AH}[/tex] intersect at the midpoint of point [tex]\overline{MT}[/tex]
Therefore, the midpoint of [tex]\overline{MT}[/tex] is a point on the diagonal line that contains the diagonal [tex]\overline{AH}[/tex]
The midpoint of [tex]\overline{MT}[/tex] = ((0 + 4)/2, (-1 + 6)/2) = (2, 2.5)
The equation of the line containing the diagonal [tex]\overline{AH}[/tex] is therefore;
y - 2.5 = (-4/7)·(x - 2)
y = -4·x/7 + 8/7 + 2.5 = -4·x/7 + 51/14

Answer:
∠ a = 30° , ∠ b = 90°
Step-by-step explanation:
∠ a and 150° are a linear pair and sum to 180° , that is
∠ a + 150° = 180° ( subtract 150° from both sides )
∠ a = 30°
------------------
the sum of the 3 angles in a triangle = 180° , that is
∠ b + ∠ a + 60° = 180°
∠ b + 30° + 60° = 180°
∠ b + 90° = 180° ( subtract 90° from both sides )
∠ b = 90°

The requried teacher needs $59.5 more to buy cups and napkins, as of the given condition.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
To find out how much more money the teachers will need to buy cups and napkins, we can first calculate the cost of each item and then add those costs together.
Each package of cups costs $3.50
The teachers need to buy 12 cups
So the total cost of cups is = 12 cups × ($3.50 per package) = $42
Now let's do the same thing for the napkins:
Each package of napkins costs $4.25
The teachers need to buy 10 napkins
So the total cost of napkins is = 10 napkins × ($4.25 per package) = $42.50
To find out how much more money the teachers will need to buy cups and napkins,
= $42 + $42.50 - $25
= $59.50 - $25 = $59.5
Therefore, the teachers will need $59.5 more to buy cups and napkins.
