Answer: See explanation
Step-by-step explanation:
Perimeter of a rectangle is given as:
= 2(length + breadth)
First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:
= 2(1.2+ 3.4)
= 2(4.6)
= 2 × 4.6
= 9.2cm
Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:
= 2(2.1 + 1.7)
= 2 × 3.8
= 7.6cm
Total perimeter = 9.2cm + 7.6cm = 16.8cm

A rectangles base is 2in. Shorter than twice its height. The rectangles area is 40in^2. Find it's dimensions.
Answer:
5 in by 8 in
Step-by-step explanation:
Given that :
Area, A of rectangle = 40 in²
Let
height = x
Base = 2x - 2
Area of rectangle = L * B
40 = x * (2x - 2)
40 = 2x² - 2x
2x² - 2x - 40 = 0
x² - x - 20 = 0
x² - 5x + 4x - 20 =0
x(x - 5) +4(x - 5) = 0
x - 5 = 0 or
x + 4 = 0
x = 5 or x = - 4
X cannot be negative
X = 5
Height = 5
Base = 2*5 - 2 = 8

We can tell this is true because of the 3x in the second on and just hte x in the first. If you look closely you'll see the coefficents for the x values is the only difference between the two.
Let's now solve
We need to get a positive variable by itself
let's take x+y=5 and solve for y
x-5= -y
y= -x+5
We can then plug this y value into the other equation
3x-(-x+5)= -5
3x+x-5= -5
4x= 0
x=0
Let's then plug this value in for x into any of the beginning equations
0+y=5
y=5
In a holiday resort, the ratio of men to women is 5:6 and the ratio of
women to children is 4:7. There are 200 men staying at the resort. How
many children are there?
Answer:
Men: 5 : 3 = 20 : 12
Women: 7 : 4 = 21 : 12
So for every 12 children there are 20 men to 21 women.
Neither men nor women compose more than half of the concert population
There are 200 men staying at the resort. Then the number of children in the resort will be 292.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
In a holiday resort, the ratio of men to women is 5:6 and the ratio of women to children is 4:7.
There are 200 men staying at the resort.
Then the number of women in the resort will be
Women / 200 = 5 / 6
Women = 500 / 3
Then the number of children in the resort will be
(500/3) / children = 4/7
children = 291.67
children ≈ 292

You often go to school by bus. You have two bus systems you could take. City Bus offers a monthly pass that costs $15 and then you pay $1 per ride. Campus Transport simply charges $2.50 per ride and does not require a monthly pass. After how many rides will the total costs of the two options be the same? Write a system of equations in order to solve this problem.
Answer:
For City Bus you will need to ride 10 times for 2 months, and for Campus Transport you need to ride 16 times.
Step-by-step explanation:
$2.50 x 2 = $5.00 so you know that the number of rides needs to even in order to have a whole number. This is because there is no way the City Bus cost will ever have cents.
$2.50 x 16 = $40.00
$15 x 2 = $30
$1 x 10 = $10
$30 + $10 = $40
So (15 x 2) + (10 x 1) = 16 x 2.50

You are tired at the end of the term and decide to borrow $500 to go on a trip to Whatever Land. You go to the bank and borrow the money at an annual rate of 11% for 6 months. Find the interest you will pay on the loan.
Answer:
$27.5
Step-by-step explanation:
P =$500, R = 11 pcpa, T = 6 months = 1/2 years
[tex]I = \frac{PRT}{100} = \frac{500 \times 11 \times \frac{1}{2} }{100} \\ \\ = 5 \times 11 \times \frac{1}{2} \\ \\ = 55 \times \frac{1}{2} \\ \\ I= \$ 27.5[/tex]

Anna opened a savings account and deposited $300.00 as principal. The account earns 1%
interest, compounded annually. What is the balance after 2 years?
Answer:
$6
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1%/100 = 0.01 per year,
then, solving our equation
I = 300 × 0.01 × 2 = 6
I = $ 6.00
The simple interest accumulated
on a principal of $ 300.00
at a rate of 1% per year
for 2 years is $ 6.00.
