1. So, Mr. Raciles should pay Php 500.00 + Php 50.00 = Php 550.00 in all.
1. To calculate the total amount Mr. Raciles should pay, we need to add the service charge to the original amount. The service charge is 10% of Php 500.00, which is:
10% of Php 500.00 = 0.10 x Php 500.00 = Php 50.00
2. To determine the percent of questions Shiela missed, we subtract her correct answers from the total number of questions and find the percentage. Shiela answered 62% of the 50 items correctly, which means she missed:
100% - 62% = 38%
So, Shiela missed 38% of the questions.
3. Jana paid Php 420.00 for a dress, which is 105% of what Queenie paid. To find the amount Queenie paid, we need to divide Php 420.00 by 105%:
Queenie's payment = Php 420.00 / 105% = Php 400.00
Therefore, Queenie paid Php 400.00.
4. Among the 920 students, 90% are walking to school. To find the number of students walking and riding to school, we can calculate it as follows:
Number of students walking to school = 90% of 920 = 0.90 x 920 = 828 students
Number of students riding to school = Total students - Students walking = 920 - 828 = 92 students
Therefore, 828 students are walking to school, and 92 students are riding to school.
5. If 60% of the voters in Barangay San Isidro are males, the remaining percentage represents the females:
Percentage of females = 100% - 60% = 40%
To find the number of females, we multiply the percentage by the total number of voters:
Number of females = 40% of 3,050 = 0.40 x 3,050 = 1,220 females
So, there are 1,220 females in Barangay San Isidro.
6. If 65% of the households received financial help, we can calculate the number of families that received aid as follows:
Number of families received financial aid = 65% of 50 = 0.65 x 50 = 32.5
Since we cannot have a fraction of a family, we round down to the nearest whole number. Therefore, 32 families received financial aid.
7. John's savings of Php 10,000.00 earns a 2% interest every month. To calculate the interest after a month, we multiply his savings by the interest rate:
Interest = 2% of Php 10,000.00 = 0.02 x Php 10,000.00 = Php 200.00
So, the interest on John's savings after a month is Php 200.00.
8. The total worth of tickets sold for Sarah Geronimo's concert is Php 2 million. The 80% gain given to the charitable institution can be calculated as follows:
Share of the charitable institution = 80% of Php 2,000,000.00 = 0.80 x Php 2,000,000.00 = Php 1,600,000.00
Therefore, the share of the charitable institution is Php 1,600,000.00.
9. If Jason answered 98% of the test correctly and there were 50 items, we can calculate the number of items he answered correctly as follows:
Number of items answered correctly = 98% of
50 = 0.98 x 50 = 49
Jason answered 49 items correctly.
10. If 90% of the 50 students in the class were present, we can calculate the number of students who attended the class as follows:
Number of students attended = 90% of 50 = 0.90 x 50 = 45
Therefore, 45 students attended the class.

(cosec a + 1)*(1 - sin a)= cos a* cot a
Answer:
See proof below
Step-by-step explanation:
Given the equation, we are to prove that it is true
(cosec a + 1)*(1 - sin a)= cos a* cot a
From LHS
(cosec a + 1)*(1 - sin a)=
Expand
cosec a - cosecasina + 1 - sina
Since cosec a = 1/sina
1/sina - (1/sina)sina + 1 - sina
1/sina - 1 + 1 - sina
1/sin a - sina
Find the LCM
1-(sin^2a)/sina
cos^2a/sina

p is directly proportional to the square of q. it is known that p=12 for a certain value of q. find the value of p when q is doubled
===========================================================
Explanation:
We're told that "p is directly proportional to the square of q", which means that we have the equation
p = k*q^2
for some constant k
Replace p with 12 because we're also told that p = 12.
So we now have this equation
12 = k*q^2
which is the same as
kq^2 = 12
We'll use this later.
-----------------------
Let's go back to the original equation. We'll replace q with 2q to represent the value of q doubling
p = k*q^2
p = k*(2q)^2 ... replace q with 2q
p = k*4q^2
p = 4k*q^2
p = 4*(kq^2)
p = 4(12) ...... replace kq^2 with 12
p = 48
Therefore, if q is doubled, then p = 12 quadruples to p = 48.

Mariana wears her winter coat when the temperature is colder than -4^{\circ}\text{C}−4 ∘ Cminus, 4, degrees, start text, C, end text. Write an inequality that is true only for temperatures (t)(t)left parenthesis, t, right parenthesis at which Mariana wears her winter coat.
Answer:
T < - 4°C
Step-by-step explanation:
Given that Mariana wears her coat only when temperature is colder than - 4°C
Recall that lower temperature values indicate higher degree of coldness ;
Hence, Mariana will only wear her coat when temperature values are lesser than - 4°C ; this means that the temperature at that period is colder than - 4°C.
Hence, the inequality expression which is only true for temperatures when Mariana wears her coat can be written as :
Temperature = T
T < - 4°C

A line passes through the point (-4,7) and has a slope of 3/2
Write an equation in slope-intercept form for this line.
Answer:
[tex]y=\frac{3}{2}x + 13[/tex]
Step-by-step explanation:
Given that [tex]x_{1}[/tex] = -4 and [tex]y_{1}[/tex] = 7 (from the point given) and m = [tex]\frac{3}{2}[/tex], we will use the equation [tex]y - y_{1} =m(x-x_{1})[/tex]. Therefore, when we substitute the given values to the equation:
y - y1 = m(x - x1)
y - 7 = 3/2(x - (-4))
y - 7 = 3/2(x + 4)
y - 7 = 3/2x + 6
y = 3/2x + 6 + 7
y = 3/2x + 13
y=3/2x+13 is the equation of line in slope-intercept form
What is slope intercept form of line?
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that a line passes through the point (-4,7)
The slope of the line is 3/2.
We need to find the equation in slope-intercept form for this line
Let us find the y intercept of line
7=3/2(-4)+b
7=-6+b
13=b
So slope intercept form is y=3/2x+13
Hence, y=3/2x+13 is the equation of line in slope-intercept form

a circle with a circumference of 40.82 centimeters what is the area of the circle is 3.14 for pi
You need two formulas for this:
C = πd or C = 2πr ( d = 2r ) Where C is circumference and d is diameter, r is radius
A = πr² Where A is area, and r is radius
First you get the diameter and radius by substituting the value of pi and circumference. With that, you can calculate the Area of the circle with the second formula. square² the radius then multiply it to 3.14. Remember that radius is half of diameter.
Answer:
[tex]\boxed {\boxed {\sf a=132.665 \ cm^2}}[/tex]
Step-by-step explanation:
1. Find the Radius
We are given the circumference of 40.82 centimeters. The formula for circumference is
[tex]c=\pi d[/tex]
The diameter is twice the radius, so we can also write this formula as:
[tex]c= \pi 2r[/tex]
Substitute 40.82 for the circumference and use 3.14 for pi.
[tex]40.82 \ cm= (3.14) 2r[/tex]
[tex]40.82=6.28 r[/tex]
6.82 and r are being multiplied. The inverse of multiplication is division. Divide both sides by 6.82
[tex]\frac{40.82 \ cm}{6.28}=\frac{6.28 r}{6.82}[/tex]
[tex]6.5 \ cm=r[/tex]
2. Calculate the Area
Now we can calculate the area using this formula:
[tex]a= \pi r^2[/tex]
The radius is 6.5 centimeters and we are using 3.14 for pi.
[tex]a= 3.14(6.5 \ cm)^2[/tex]
Solve the exponent.
(6.5 cm)²= 6.5 cm * 6.5 cm=42.45 cm²[tex]a= 3.14 (42.45 \ cm^2)[/tex]
Multiply.
[tex]a=132.665 \ cm^2[/tex]
The area is 132.665 square centimeters.
