A computer costs £964. A tax of 18.5% is then added to the cost of the
computer.
Work out the amount of tax that is added to the cost of the computer.
Give your answer in pounds (£).
Answer:
The amount of tax is £178.34, and the full total is £1142.34.
Step-by-step explanation:
Use a calculator to find 18.5 percent of 964, giving us the answer we need. You may add this to the cost before tax to find the exact price after tax.
The amount of tax that is added to the cost of the computer is
£178.34.
What is tax?A compulsory contribution to state revenue, levied by the government on workers' income and business profits, or added to the cost of some goods, services, and transactions.
Given is that a computer costs £964. A tax of 18.5% is then added to the cost of the computer.
Assume the amount of tax that is added to the cost of the computer is
£{x}. Then, we can write the equation as -
{x} = 18.5% of 964
{x} = (18.5/100) x 964
{x} = 178.34
Therefore, the amount of tax that is added to the cost of the computer is
£178.34.

Find the slope of the line that passes through (3, 3) and (9,8). Simplify your answer and write it as a proper fraction, improper fraction, or integer
Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
In order to find the answer, you need to use the slope formula, substitute, subtract, and simplify if needed.
Slope formula = [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
[tex]\frac{y^2-y^1}{x^2-x^1}=\frac{8-3}{9-3}[/tex]
[tex]8-3 = 5[/tex]

Step-by-step explanation:
You can eliminate the choices that don't make any sense by comparing the given numbers to the offered choices:
given:
15 in : 750 mi
__
A. 1 in : 50 mi . . . . . . . . equivalent to dividing the given ratio numbers by 15
B. 15 in : 100 mi . . . . . . same inches, wrong miles
C. 1 in : 750 mi . . . . . . . wrong inches, same miles
D. 1 mi : 50 in . . . . . . . . both inches and miles are wrong (the ratio has the units swapped)
__
In the given ratio, the numerical number of miles (750) is 50 times the numerical number of inches (15). This is the ratio you're looking for among the answer choices. You need to pay attention to both the numerical values and their associated units.

Help me: Solve: z^4 = -4
All answers should be in the format a+bi where a and b are real numbers
z²-2i=0
Answer:
Solution given:
z⁴=-4
doing square root on both side
[tex]\sqrt{z⁴}=\sqrt{2²*-1}[/tex]
we know i²=-1
substituting i² we get
z²=[tex]\sqrt{2²*i²}[/tex]
z²=2i
z²-2i=0 is a required answer. where
z² and 2 is real number.
Answer:
z = {-1 -i, -1 +i, 1 -i, 1 +i}
Step-by-step explanation:
Using Euler's formula, we can write the equation as ...
z^4 = 4e^(i(π +2πn)) . . . . . . where n is any integer
Then the 4th root is ...
z = (√2)e^(i(π +2πn)/4 = (√2)e^(i(π/4 +nπ/2)) . . . . . for n = 0–3
z = √2(cos(π/4+nπ/2) +i·sin(π/4 +nπ/2)) . . . . . for n = 0–3
z = ±1 ±i
z = {1 +i, -1 +i, -1 -i, 1 -i}
_____
Additional comment
Values of n are only needed in the range 0–3, because the answers repeat for values other than those.

how to turn x+7y=20 into y=mx+b
Answer:
y = -1/7x +20/7
Step-by-step explanation:
Solve for y.
7y = -x +20 . . . . . subtract x from both sides to get the y-term by itself
y = -1/7x +20/7 . . . . divide both sides by the coefficient of x
In this form, you can see ...
m = -1/7b = 20/7 = 2 6/7Answer:
y=-1/7x+20/7
Step-by-step explanation:
So they are asking us to put x+7y=20 into slop-intercept form (y=mx+b).
They're pretty much just asking us to solve for y.
x+7y=20
7x=20-x (Subtract x from both sides)
y=20-x/7 (Divide 7 on both sides to isolate y)
y=20/7-1/7x
y=-1/7x+20/7
So..
m=-1/7
b=20/7

Steven has $150. John has J dollars. Steven has 30 less than 2 times the amount John has. How much does John have?
Answer:
J = 90
John has 90 dollars.
Step-by-step explanation:
We need to find how much money John has. To find how much J equals we need to break it down.
We already know that Steven has 150 dollars. We also know that he has 30 less than two times the amount John has.
Steven has 30 less than two times the amount John has.
So 150 + 30 = 180
180 is two times the amount John has.
Because 180 is two times the amount John has we need to divide by two.
180 ÷ 2 = 90.
J = 90. Therefore John has 90 dollars.

In the figure, one exterior angle is drawn at each vertex of the triangle. Explain how to find the sum of the measures of these three exterior angles.
Explanation:
Here's one way:
At vertex A, draw the vertical angle to the given angle 4. That is, extend AC, rather than AB to show the exterior angle at that vertex.
Now, collapse triangle to one with zero area, so that vertices A, B, C lie on top of each other. You can do this using a dilation scale factor f such that f→0.
The result is that the exterior angles divide the circular space around point ABC into three parts that sum to 360°. Essentially, we have copied each of the exterior angles to the same vertex.
The sum of the measures of the exterior angles is 360°.
_____
Additional comment
This identical approach can be used to show the sum of exterior angles around any convex polygon is always 360°.

1. Timmy wants to buy a scooter and the price was $50. When he goes to the store a second time, he found that price was marked down by 20%. What is the new price?
2. A football is selling for 35% off the original price. The original price was $60. What is the sale price of the football?
The new price of the scooter will be:
= $50 - (20% × $50)
= $50 - $10
= $40
The sale price of the football will be:

Laura just became a personal trainer and is finalizing her pricing plans. One plan is to charge
$55 for the initial consultation and then $41 per session. Another plan is to charge $50 for the
consultation and $46 per session. Laura realizes that the two plans have the same cost for a
certain number of sessions. How many sessions is that? What is that cost?
Using algebraic equations:
the number of sessions that will give same cost for both plans is: 1
the cost is: $96
Translate the situation into algebraic equations.
Let y = Total cost x = number of sessionsEquation for total cost of the first plan:
y = 41x + 55
Equation for the total cost of the second plan:
y = 46x + 50
To find the number of sessions that would yield same cost for both plans, make both equations equal to each other and solve for x.
41x + 55 = 46x + 50
Combine like terms together41x - 46x = - 55 + 50
-5x = -5
x = 1
For a session, both plans will yield the same cost.
The cost 1 session will yield for both:
41x + 55 = 46x + 50
Plug in the value of x41(1) + 55 = 46(1) + 50
96 = 96
Therefore, using algebraic equations:
the number of sessions that will give same cost for both plans is: 1
the cost is: $96

Using distance between two points, it is found that the total distance covered on the tour is of 3400 miles.
Given two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], their distance is given by:
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
In this problem, the formula is used to find the distance covered on each tour, hence:
[tex]d_{AB} = \sqrt{(400 - 0)^2 + (300 - 0)^2} = 500[/tex]
[tex]d_{BC} = \sqrt{(-800 - 400)^2 + (800 - 300)^2} = 1300[/tex]
[tex]d_{CD} = \sqrt{(-800 - (-800))^2 + (0 - 800)^2} = 800[/tex]
[tex]d_{DA} = \sqrt{(0 - (-800))^2 + (0 - 0)^2} = 800[/tex]
Then, the total distance is given by the sum of each separate distance, hence:
[tex]d = d_{AB} + d_{BC} + d_{CD} + d_{DA} = 500 + 1300 + 800 + 800 = 3400[/tex]
The total distance covered on the tour is of 3400 miles.
