You purchased a new graphing calculator for the total cost of $103.44, which includes the 10% sales tax.
What was the original price of the calculator?
The original price of the calculator is $94.04
The total cost includes a 10% sales tax on the original cost.
Assume the original cost is denoted by "c" then the correct expression would be:
Total cost = Original price x ( 1 + 10%)
103.44 = c x (1 + 10%)
103.44 = 1.1c
c = 103.44 / 1.1
c = $94.04
Original price was $94.04

Answer:
y ≈ 2.262
Step-by-step explanation:
Using the rule of logarithms
log[tex]x^{n}[/tex] = nlogx
Given
[tex]3^{y}[/tex] = 12 ( take log of both sides )
log[tex]3^{y}[/tex] = log12 , then
ylog3 = log12 ( divide both sides by log3 )
y = [tex]\frac{log12}{log3}[/tex] ≈ 2.262 ( to 3 dec. places )

A camera has a listed price of 587.99 before tax. If the sales tax rate is 7.75%, find the total cost of the camera with sales tax included.
Answer:
Total cost = 633.559225
Step-by-step explanation:
First we can calculate the tax cost for the camera: 7.75% × 587.99 = 45.569225
That is the tax sale or cost.
Then we calculate total cost by adding the listed price with the tax cost:
587.99 + 45.569225 = 633.559225
Just remember these simple equation:
Step 1: Tax Cost = Tax Percentage × Listed Price
Step 2: Total cost = Tax Cost + Listed Price (original price)

A square plot of land has side lengths of 40 meters. An archeologist divides the land into 64 equal parts What is the area of
each part?
Find the area of the plot of land:
40 x 40 = 1600 square meters.
Now divide total area by parts:
1600 / 64 = 25 square meters.
Answer: 25 square meters
Step-by-step explanation:
Area of each part = Area of plot/Total parts
Area = 40 × 40/64
Area = 10 × 40/16
Area = 10 × 10/4
Area = 100/4
Area = 25 m²

A 12 oz can of soda costs $0.72. A 20 oz bottle of the same soda costs $1.40. Which is the better deal?
The diagram represents the fencing around a backyard. The fence is formed with parallel lines and a half circle. Write and solve an equation to determine how many feet of fencing are needed. Round the answer to the nearest tenth.
The amount of fence needed is the perimeter of the fence. The amount of fence needed is 127.1ft
From the diagram of the fence, we have:
[tex]r = 15[/tex] ---- the radius
[tex]l = 40ft[/tex] -- the length of the parallel lines
First, we calculate the length of the arc surrounding the half circle
This is calculated using:
[tex]L = \frac{\theta}{360} \times 2\pi r[/tex]
Because it is a half circle
[tex]\theta = 180[/tex]
So, we have:
[tex]L = \frac{\180}{360} \times 2 \times 3.142 \times 15[/tex]
[tex]L =0.5 \times 2 \times 3.142 \times 15[/tex]
[tex]L =47.13[/tex]
The amount of fence needed is the sum of the length of parallel lines and the semicircle.
So, we have:
[tex]Amount = L + l + l[/tex]
[tex]Amount =47.13 + 40 + 40[/tex]
[tex]Amount =127.13[/tex]
Approximate
[tex]Amount =127.1[/tex]
Hence, the amount of fence needed is 127.1ft

2. Given that tan 25º = a, express each of the following in terms of a.
tan 205
sin 25°
cos 65
cos 245
9514 1404 393
Answer:
tan(205°) = asin(25°) = (a√(a²+1))/(a²+1)cos(65°) = (a√(a²+1))/(a²+1)cos(245°) = -(a√(a²+1))/(a²+1)Step-by-step explanation:
The tangent function is periodic with a period of 180°. So ...
tan(205°) = tan(25°) = a
__
The identity relating sine and tangent is ...
sin(x) = tan(x)/√(tan²(x)+1)
Rationalizing the denominator gives ...
sin(x) = tan(x)√(tan²(x)+1)/(tan²(x)+1)
sin(25°) = a√(a²+1)/(a²+1)
__
cos(65°) = sin(25°) = a√(a²+1)/(a²+1)
__
cos(245°) = -sin(25°) = -a√(a²+1)/(a²+1)

Select three involuntary muscles:
stomach
intestinal
heart
biceps
brain
I'll give Brainliest! :D
Answers:
A) stomachB) intestinalC) heart=============================================
Explanation:
The stomach muscle helps digest food. The muscle isn't something a person can control at will. Instead, the body handles it automatically. This is why choice A is one of the answers.
The intestinal muscles work in a similar fashion to help pass nutrients into the blood stream and also pass waste out of the body. All of these processes are done automatically and you don't have to think about them. They just happen. Therefore, choice B is another answer.
Another example of an automatic or involuntary muscle doing its own thing is the heart muscle. It continuously pumps blood to help distribute nutrients and oxygen, and also dump waste byproducts (eg: carbon dioxide) out of the body. So choice C is the third and final answer.
An example of a muscle that's voluntary are the biceps. You can flex these muscles, and move them around at will. For example, when you pick up an item. So this allows us to rule out choice D.
I'm not sure why your teacher listed "brain". It has properties related to muscles such as the idea of practicing a topic to help retain it (similar to exercising to stay in shape); however, the brain itself isn't a muscle on a technical biological level.
--------------------
Extra info:
Some more involuntary muscles are:
The diaphragm muscle to help the lungs expand and contract (to breathe in oxygen or exhale carbon dioxide).The muscles that allow your eyes to blink. The technical name for them isn't coming to mind at the moment. These muscles blink at some fairly random yet consistent rate, and also blink whenever something like dust particles enter the eye (or threaten to).At some level, you could argue that the biceps are involuntary in some way. What I mean by this is that there's a reflex action to them that is automatically controlled. However, for the most part, the biceps are voluntary muscles.please help me, if you help then thanks!

Step-by-step explanation:
[tex]8x - 3 = 5 + 4y[/tex]
Isolate y first subtract 5 from both sides
[tex]8x - 8 = 4y[/tex]
Divide both sides by 4.
[tex] \frac{8x - 8}{4} = y[/tex]
[tex]2x - 2 = y[/tex]
y= 1
Step-by-step explanation:
Solve for y:
8x - 3 = 5 + 4y
8x = 4y + 5+3
Divide both sides by 8
x = 1÷2y + 1
plug into equation
8 (1÷2y +1) - 3 = 5 + 4y
Distribute
8÷2+ 8 - 3 = 5 + 4y
4 + 5 -5 = 4y
Combine like item
4 = 4y
divide both sides by 4
y= 1
