Penelope is now 3 times the age of jaslin. If jaslin will be 12 in 3 years, how many years ago was Penelope 13 years ago?
Answer:
Penelope is 14 years old.
Step-by-step explanation:
- Jaslin is 9 years old (since she'll be 12 in 3 years)
- So, you multiply 9 by 3 (since Penelope is 3 times Jaslin's age), which gives you 27.
- Then minus 13 from 27 (since we're solving for how old Penelope was 13 years ago), which gives you 14

Find the Perimeter of a Ractangle whose Length and Breadth are 9.6 cm and 7.9 cm respectively .Answer :-
Perimeter of a Ractangle is 35 cm .[tex] \rule {210pt} {2pt} [/tex]
Given :-
Length of Rectangle = 9.6 cmBreadth of Rectangle = 7.9 cmTo Find :-
Perimeter of Rectangle = ?Solution :-
As per the provided information in the given question, we have been given that Length of Rectangle is 9.6 cm . Breadth of Rectangle is given 7.9 cm . And, we have been asked to calculate the Perimeter of Rectangle .
For calculating the Perimeter , we will use the Formula :-
[tex] \bigstar \: \: \boxed {\sf { \: Perimeter \: _{Rectangle} = 2 \times [ \: Length + Breadth \: ] \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
⇒ Perimeter = 2 × [ Lenght + Breadth ]
⇒ Perimeter = 2 × [ 9.6 + 7.9 ]
⇒ Perimeter = 2 × 17.5
⇒ Perimeter = 35
Hence :-
Perimeter = 35 cm .[tex] \underline {\rule {210pt} {4pt}} [/tex]

q=65
r=115 How?
[tex]\\ \rm{:}\dashrightarrow p+120=180[/tex]
[tex]\\ \rm{:}\dashrightarrow p=60[/tex]
And
q=65°(Opposite angles are equalNow
[tex]\\ \rm{:}\dashrightarrow r+65=180[/tex]
[tex]\\ \rm{:}\dashrightarrow r=115[/tex]
So
[tex]\\ \rm{:}\dashrightarrow x=q(Opposite interior angles)=65[/tex]
y=p=60°Answer:
p = 60°
r = 115°
q = 65°
y = 60°
x = 65°
Step-by-step explanation:
Linear pair: a pair of adjacent angles formed when two lines intersect. The two angles are always supplementary and so their measures sum to 180°.
Therefore, the linear pairs are:
p + 120° = 180°
⇒ p = 60°
r + 65° = 180°
⇒ r = 115°
-----------------------------------------------------------------------------------
Vertical angle theorem: a pair of opposite angles formed by intersecting lines. Vertical angles are always congruent (equal).
Therefore, the vertical angles are q and 65°:
⇒ q = 65°
-----------------------------------------------------------------------------------
Consecutive interior angle theorem: if a transversal intersects two parallel lines, each pair of consecutive interior angles is supplementary and so their measures sum to 180°.
Therefore, the consecutive interiors angles are:
120° + y = 180°
⇒ y = 60°
x + r = 180°
⇒ x + 115° = 180°
⇒ x = 65°

What is Algebra?Algebra is a branch of mathematics that deals with symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables. In our real-life problems, we often see certain values that keep on changing. But there is a constant need to represent these changing values. Here in algebra, these values are often represented with symbols such as x, y, z, p, or q, and these symbols are called variables. Further, these symbols are manipulated through various arithmetic operations of addition, subtraction, multiplication, and division, with an objective to find the values.
Algebraic ExpressionsAn algebraic expression in algebra is formed using integer constants, variables, and basic arithmetic operations of addition(+), subtraction(-), multiplication(×), and division(/). An example of an algebraic expression is 5x + 6. Here 5 and 6 are fixed numbers and x is a variable.
Given:
John is 3 years older than Mary.
Five years ago he was four times as old as Mary was then.
let the age of mary be x
John's age= x+ 3
Five years age,
Mary's age= x-5
john's age = x-2
So,
x-2= 4( x-5)
x- 2 = 4x- 20
-3x= -18
x=3
Hence, john's age= 9 years

The Todd family plans to start a small business. Mr. Todd borrows $10,000 from the blank at an annual interest rate 8%for 36 months what's his interest he will pay on his loan
Answer: They will end up paying $2,400.
Step-by-step explanation:
Since the annual interest rate is 8% of $10,000, take 8% of 10,000 by multiplying these numbers. This gives you $800.
This is only the annual interest rate, the Todd family's loan and interest isn't paid until 36 months have passed. Since 36 months is equal to 3 years, we can multiply the annual rate by 3. (800*3)
The Todd family will pay $2,400 in interest by the end of the period.
Billy’s employer pays for 65% of his annual health insurance premium. billy has the rest deducted in equal amounts from his paycheck. if billy has $105.73 withheld from his paychecks twice each month, how much does his employer contribute towards his health insurance on an annual basis? a. $683.18 b. $1,366.36 c. $2,356.27 d. $4,712.54

What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Billy’s employer pays for 65% of his annual health insurance premium.
Billy has the rest deducted in equal amounts from his paycheck.
If billy has $105.73 withheld from his paychecks twice each month.
His employer contributes towards his health insurance on an annual basis.

what's 5 divided by 3 1/3?
Answer: 3/2
Step-by-step explanation:
We can start by converting 3 1/3 to an improper fraction. Since 3 is equal to 9/3, 3 1/3 would be equal to 9/3 + 1/3 = 10/3.
Therefore, we are doing [tex]\frac{5}{\frac{10}{3}}[/tex].
Dividing 5 by 10/3 is the same as multiplying 5 and the reciprocal of 10/3, which is 3/10.
5*3/10 = 15/10 = 3/2.
