Edward spends £610 on a plane ticket and $180 on airport tax. Using £1 = $1.34, what percentage of the total cost does Edward spend on airport tax? Give your answer rounded to 1 dp.
Answer: 18.0%
Step-by-step explanation:
Given: Cost of plane ticket = £610 = $ 610 x 1.34 [ £1 = $1.34 ]
= $ 817.4
Airport tax = $180
Total cost = $(817.4+180)= $997.4
The percentage of the total cost does Edward spend on airport tax = [tex]\dfrac{180}{997.4}\times100\approx18.0\%[/tex]
Hence, the required answer = 18.0%

Here is a rectangle ABCD.
A
B
20 cm
30 cm
The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.
Answer: 8%
Step-by-step explanation:
Original Perimeter of the rectangle is:
= 2 * ( Length * Width)
= 2 * (20 + 30)
= 100 cm
The length increased by 10%. It therefore increased to:
= 30 * ( 1 + 10%)
= 30 * 1.1
= 33 cm
The width increased by 5%. It increased to:
= 20 * ( 1 + 5%)
= 21 cm
New Perimeter is therefore:
= 2 * ( 33 + 21)
= 108 cm
Percentage increase in perimeter is:
= (New perimeter - old) / old perimeter
= (108 - 100) / 100
= 8%

B.
AD = 10 cm
AB = 9 cm
D0= 6 cm
Angle ABC = angle BCD = 90°
Calculate the length of AC.
Give your answer correct to 3 significant figures.
Answer:
12.04
Step-by-step explanation:
use Pythagorean theorem to find BC then to find ac.
The length of AC from the given trapezium is 12.042 cm.
In the given trapezium, AD=10 cm, AB=9 cm, DC=3 cm.
Draw perpendicular from D to AB, intersecting at X.
So, AX=6 cm
By using Pythagoras theorem, we get
AD²=AX²+DX²
10²=6²+DX²
100=36+DX²
DX²=100-36
DX²=64
DX=8 cm
Here, DX=BC=8 cm
Now, consider triangle ABC and apply Pythagoras theorem, we get
AC²=AB²+BC²
AC²=9²+8²
AC²=81+64
AC²=145
AC=√145=12.042 cm
Therefore, the length of AC from the given trapezium is 12.042 cm.

The width of a rectangle is 7x-7 feet and the length is 4x+9 feet , what is the perimeter of the rectangle?? PLS HELP ASAP!!!!!!!!!
Answer:
The perimeter of rectangle is 22x+4 feet.
Step-by-step explanation:
Width of rectangle = 7x-7 feet
Length of rectangle = 4x+9 feet
We need to find perimeter of rectangle.
The formula used is:
[tex]Perimeter\: of\: rectangle=2(Length+ Width)[/tex]
Now, putting values and finding perimeter
[tex]Perimeter\: of\: rectangle=2(Length+ Width)\\Perimeter\: of\: rectangle=2(4x+9+ 7x-7)\\Perimeter\: of\: rectangle=2(4x+7x-7+9)\\Perimeter\: of\: rectangle=2(11x+2)\\Perimeter\: of\: rectangle=22x+4\:feet[/tex]
So, the perimeter of rectangle is 22x+4 feet.

Convert from standard to slope intercept form 3x -y= -1
Answer:
y= 3x + 1
Step-by-step explanation:solve for y
subtract 3x from the left which leaves -y= -3x -1
then you have to take flip the signs or divide by -1 so it comes out to y=3x + 1
Answer:
y = 3x + 1
Step-by-step explanation:
Slope Intercept form is written out as the following:
y = mx + b
In order to convert "3x - y = -1", we first subtract 3x from both sides, giving us:
-y = -3x - 1
Since we have "-y", we multiply -1 on both sides.
-1(-y) = -1(-3x - 1)
Multiplying two negatives makes a positive, hence when we multiply -1 on both sides, it becomes this:
y = 3x + 1
So converting to the Slope Intercept form ends up being "y = 3x + 1"
What is the value for x?
Answer:
All angles must add up to 180, so if you add 69+5x+2+9y-3, it is = to 180.
First we can subtract 68 cancelling out 69, 2 and -3 so it is
5x+9y = 112. I assume this is an iscoceles triangle so we already knew 9y - 3 = 69, y=8, x=8

A study of black bears in the Adirondacks reveals that their population can be represented by the function , where is the number of years since the study began. Write a function that models the monthly growth rate (to the nearest hundredth of a percent) of the black bear population
Answer:
[tex]\mathbf{ P(t) = 3500 (1.}00206)^{12t}[/tex]
Step-by-step explanation:
The missing value of the given function is:
[tex]P(t) = 3500 (1.025)^t[/tex]
where
t = no. of years since study began
∴
[tex]P(t) = 3500 (1+0.025)^t[/tex]
Per year, the function can be written as:
[tex]P(t) = 3500 (1+\dfrac{25}{1000})^t[/tex]
For monthly growth rate m = 12
[tex]P(t) = 3500 (1+\dfrac{25}{1000(m)})^{mt}[/tex]
[tex]P(t) = 3500 (1+\dfrac{25}{1000(12)})^{12t}[/tex]
[tex]P(t) = 3500 (1+\dfrac{25}{12000})^{12t}[/tex]
[tex]P(t) = 3500 (1+0.00206)^{12t}[/tex]
[tex]\mathbf{ P(t) = 3500 (1.}00206)^{12t}[/tex]
A company makes flower pots. The flower pots have an expense equation of E = 2.75q + $24,582. What is
the fixed cost in the expense function
Answer:
$24,582
Step-by-step explanation:
E = 2.75q + $24,582
The expense equation above has the general relation :
Expense = [(variable cost * number of units) + fixed cost]
The fixed cost incurred is not dependent on the number of units purchased or produced and as such is usually regarded as a constant in the formula.
Thus, the fixed cost in the expense equation is thus : $24,582
