David bought a computer that was 20%
off the regular price of 1,080.if an 8%
sales tax was added to the cost of the
computer what was total price david
paid for it
Answer:
The total price David paid for the computer is $933.12
Step-by-step explanation:
The cost of the computer will be $1,080 with 20% off and 8% sales tax.
20% of 1080 is 1080(0.20)=216 this means 216 is 20% of 1080, so with the discount the price will be 1080-216=$864
Now we have to find 8% of 864.
864(0.08)=$69.12
So the total price will be 864+69.12= $933.12

small L rectangle 8 x 6 =48
two L triangles 2 * 1/2 * 2 * 8 = 16
Large rectangle 18 x 10 = 180
two R triangles 2 * 1/2 3 x 8 =24 Total = 268 yds^2
Pls answer the follwing
Answer:
Step-by-step explanation:
4 (x + 2) =30
4x + 8 = 30
4x = 30 - 8
4x = 22
x = 22 : 4
x = 5.5
check
(5.5 + 2) * 4 = 30
the answer is good
Answer:
the cost of each sandwich is 5.5
Step-by-step explanation:
we have,
4(x+2) = 30
we know a(b+c) = ab+ac
so, when we open the bracket we get,
4(x+2) = 4x+4*2 which is equal to 4x+8
so, 4x+8 = 30
=> 4x = 30 - 8 [transposing method]
=> 4x = 22
=> x = 22/4
=> x = 5.5

The volume of a cylinder is 4πx3 cubic units and its height is x units.
Which expression represents the radius of the cylinder, in units?
: 2x, 4x
Expression represents the radius of the cylinder, 2x units.
What is a cylinder?
A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
Given that:
Volume of cylinder =[tex]4\pi x^{3}[/tex]
we know that, Volume of cylinder = [tex]\pi r^{2} h[/tex]
[tex]4\pi x^{3}[/tex]= π * [tex]r^{2}[/tex] *h
[tex]4x^{3} = r^{2}*h[/tex]
[tex]4x^{3} = r^{2}*x[/tex] [since, height=x]
[tex]4x^{2} = r^{2}[/tex]
r= 2x
Hence the radius of the cylinder is 2x units

The equation y = kx represents a proportional relationship between x and y, where k is the constant of proportionality. For a moving object, the equation d = st represents a proportional relationship between distance (d) and speed (s) or between distance (d) and time (t). Explain the different ways that you can define the constant of proportionality for this equation.
Answer:
Hello!!!
In this specific case the constant of proportionality is s (speed).
Step-by-step explanation:
The constant of proportionality stay "constant" (as the name suggests) in a certain case.
meaning, the speed itself remains constant at any given distance or time.
You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.
you can also switch up the formula:
d=st
t=d/s
s=d/t

The area of a circle is 60.12cm find the length of the radius rounded to 2 dp.
Answer:
Before you write the answer to your question, make sure the question is asking for the actual value of pi or 3.14.
If the question was asking for the question to be completed with the ACTUAL VALUE of pi, then your answer is ----> 4.37
If the question was asking for the question to be completed with the rounded of pi (3.14), then your answer is ----> 4.38
It's a subtle difference, but remember, there is no such thing as close in math, it's either right or wrong.
Step-by-step explanation:
Given: Circle's Area, 60.12
As the value of pi was not directly stated, I will divide the answer into 2 portions, portion one with the answer with the actual infinite value of pi, and one where I will describe how to do it with 3.14 as pi.
Explanation with 3.14:
First thing first, know the formula for calculating the area of a circle:
[tex]A = \pi r^2[/tex]
[tex]A[/tex] stands for Area, and [tex]r[/tex] stands for Radius
Now, plug in the given values:
[tex]60.12 = \pi r^2[/tex]
Next, replace 3.14 for pi:
[tex]60.12 = (3.14)r^2[/tex]
Then, divide both sides by 3.14 ,which gives us:
[tex]19.15 = r^2[/tex]
Please note: 19.15 is rounded
Anyway, to isolate [tex]r[/tex], we take the square root of both sides:
[tex]\sqrt{19.15} = \sqrt{x^2}[/tex]
The square root and square on the right side of the equation cancel out, and we are left with:
[tex]4.38 = r[/tex]
Please note that 4.38 was rounded

There are 7 seniors on the high school soccer team. Two of them will be
chosen to be co-captains. How many ways are there to choose the co-
captains?
Decide if this is a permutation or a combination, and then find the number of
ways to choose the co-captains.
The action to choose two among the seven seniors to be cocaptains is a combination and there are 21 different choices.
What is a the difference between permutation and Combination?The major difference between permutation and Combination lies in the fact that the different ways of arranging a set of objects into a sequential order are termed as Permutation while one of the several ways of choosing items from a large set of objects, without considering an order is termed as Combination.
On this note, the action is a combination and the number of ways is; 7!/5!2! = 21.

A pole 3.8 m high casts a shadow that measures 1.3 m. A nearby tree casts a shadow 7.8 m long. Find the height of the tree.
Answer:
22.8 m
Step-by-step explanation:
the 2 situations are similar triangles
the ratio of corresponding sides are in proportion
let h be the height of the tree , then
[tex]\frac{h}{3.8}[/tex] = [tex]\frac{7.8}{1.3}[/tex] ( cross- multiply )
1.3h = 29.64 ( divide both sides by 1.3 )
h = 22.8 m
