What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
It takes an old printer 8 hours to print all the pictures for the yearbook.
A modern printer can do the same job in 5 hours.
If both work together,
it will take,
x(1/8 + 1/5) = 1
x(8 + 5)/40 = 1
8x + 5x = 40
x = 40/13
x = 3.07
x = approximately 3.1 hours.
Therefore, the work will be done in 40/13 hours.

Monica deposits $300 into a savings account that pays a simple interest rate of 4.2% paul deposits $400 into a savings account that pays a simple interest rate of 3.8% monica says that she will earn more interest in 1 year because her interest rate is higher is she correct?
Answer:
Paul earned $2.6 more interest than Monica.
Step-by-step explanation:
Giving the following information:
Monica:
Initial investment= $300
Interest rate= 4.2%
Paul:
Initial investment= $400
Interest rate= 3.8%
To calculate the income earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
Monica:
I= 300*0.042*1= $12.6
Paul:
I= 400*0.038*1= $15.2
Paul earned $2.6 more interest than Monica.
Using the variable n for the term, describe the sequence.
Answer:
3 + 5n
Step-by-step explanation:
This is an arithmetic sequence.
First term = a = 8
Common difference = d =Second term - first term
= 13 - 8
= 5
Nth term = a + (n- 1)*d
= 8 + (n -1) * 5
= 8 + n*5 - 1 *5
= 8 + 5n - 5
= 8 - 5 + 5n
= 3 + 5n

Angela is 4 feet 7 inches tall. Angela's doll is 11 inches tall. What is the ratio of Angela's height to the
doll's height?
Answer: 5:1 (simplified and in inches)
Step-by-step explanation:
Let’s convert Angelicas height in inches so all the measurements are the same.
Anglelicas height: 4 ft7 in
OR
Angelicas height: 55 inches
Dolls height: 11 inches
The ratio would be 55:11 but we would need to simplify since both numbers are divisible by a GCD (greatest common denominator)
55 and 11 are both divisible by 11 so the new simplified ratio would be...
5:1

How many metres of lights will Tom need to go all around his house?
Answer:
525 meters
Step-by-step explanation:
Tom needs 100 meters of lights to go all around his house if Tom wants to put up Christmas lights around his house.
What is a rectangle?It is defined as the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that:
Tom wants to put up Christmas lights around his house.
His house is a rectangle that is 35m long and 15m wide.
To find the how many meters of lights will Tom need to go all around his house.
Find the perimeter of the rectangle:
The perimeter of the rectangle = 2(length + width)
Length = 35 m
Width = 15 m
The perimeter of the rectangle = 2(35 + 15)
The perimeter of the rectangle = 2(50)
The perimeter of the rectangle = 100
Thus, Tom needs 100 meters of lights to go all around his house if Tom wants to put up Christmas lights around his house.

Answer:
Area of rectangle = 80
Area of Half Circle 8π
Step-by-step explanation:
The area of the rectangle is width x length, so:
Area of Rectangle: 8x10=80 ft^2
Since we know that this is a rectangle, opposite sides are equal, hence the half circle's diamiter being 8 as well.
The area of a circle is πr^2 and half-circle being πr^2/2, so with radius 4 (d/2= 8/2=4)
Area of half circle= π(4)^2= 16π/2= 8π
