Find the total cost for a $579 smartphone with 5% sales tax
Answers
Final cost: $550.05
Final answer:
To calculate the total cost including a 5% sales tax on a $579 smartphone, convert the tax rate to a decimal and multiply it by the price, then add the result to the original price. The total cost would be $607.95.
Explanation:
To find the total cost for a $579 smartphone with a 5% sales tax, you'll need to calculate the amount of sales tax and then add it to the original price of the smartphone. Here's how you would do that step by step:
Firstly, convert the sales tax from a percentage to a decimal by dividing by 100. For 5%, you would calculate 5 ÷ 100 = 0.05.
Next, calculate the sales tax by multiplying the original price by this decimal. You do this by calculating $579 × 0.05 = $28.95 in sales tax.
Finally, add the sales tax to the original price to find the total cost. Add the two amounts together to get $579 + $28.95 = $607.95.
So, the total cost of the smartphone including sales tax would be $607.95.
an observer on a cliff 1200 feet above sea level sights two ships due East. The angle of depression to the shops are 48° and 33°. What is the distance between the ships?
Answers
The problem involves using trigonometry, specifically the tangent function, to determine the distance between the two ships. By calculating the distance from the observer to each ship separately and finding the difference, we find the distance between the two ships to be approximately 814.61 feet.
Explanation:The problem at hand involves the use of trigonometry, specifically tangent of an angle in a right triangle. Since we are dealing with angles of depression, we must understand that these angles are taken from a horizontal line - in this case, the line of sight from the cliff's edge.
First, let's consider the observer and the further away ship using tangent as follows:
tangent of 33° = height/distance, thus distance to the further ship = height / tangent of 33° = 1200 / tan(33) approximately equals to 1809.54 feet.Similar steps for nearer ship with angle of 48 degrees:
tangent of 48° = height/distance, hence distance to the closer ship = height / tangent of 48° = 1200 / tan(48) approximately equals to 994.93 feet.Therefore, the distance between the ships is the difference between the two distances calculated above, which will be 1809.54 - 994.93 = 814.61 feet.

To determine the distance between the two ships, use the angles of depression and the observer's height above sea level to find the horizontal distances to each ship with trigonometry and subtract the smaller from the larger.
Explanation:To calculate the distance between two ships using their angles of depression from an observer's viewpoint atop a cliff, we can employ trigonometry. Let us denote the observer's vertical distance above sea level as height (h), which is 1200 feet in this case. The angles of depression to the first and second ship are 48° and 33° respectively.
We will use the tangent of these angles to find the horizontal distances (d1 and d2) from the base of the cliff to each ship:
Using the tangent of the angle of depression 48° to find distance to first ship (d1):tangent(48°) = opposite/adjacent or, h/d1
Thus, d1 = h / tangent(48°)Using the tangent of the angle of depression 33° to find distance to second ship (d2):
tangent(33°) = opposite/adjacent or, h/d2
Thus, d2 = h / tangent(33°)
After finding d1 and d2, we subtract the smaller distance from the larger to get the distance between the two ships:
Distance between ships = d2 - d1
Finally, we convert the answer from feet to the desired unit if necessary.

Erma maintains an active blog about her seashell collection. She has 500 white shells, 325 yellow shells, 115 pink shells, and 60 green shells in her jar. She asks Sweet T to reach into her jar and randomly selects a shell. Then she replaces it and shakes up the jar before asking Sweet T to pick another shell. Which model shows the probability of a randomly selecting each color shell from her jar?
A. White 60% Pink: 10% yellow: 20% Green: 10%
B.White: 50% Pink: 11% yellow: 32.5% green: 6%
C. White: 25% Pink: 25% Yellow: 25% Green: 25%
D. White: 100% Pink: 23% Yellow: 65% Green: 12%
Answers
B. White: 50% Pink: 11% yellow: 32.5% green: 6%
I believe there is a small typo here, as the probability of pink should be 11.5%
based on the calculations below.
Explanation:
probability of each color=number of shells of this color/total number of shells
To get it in percentage form, we will then multiply the probability by 100
We have:
number of white shells = 500 shells
number of pink shells = 115 shells
number of yellow shells = 325 shells
number of green shells = 60 shells
total number of shells = 500 + 115 + 325 + 60 = 1000 shells
Now, we will get the probability of each color as follows:
probability of white shells = (500/1000) * 100 = 50%
probability of pink shells = (115/1000) * 100 = 11.5%
probability of yellow shells = (325/1000) * 100 = 32.5%
probability of green shells = (60/1000) * 100 = 6%
Hope this helps :)
If you add the number of seashells Erma has in total, it would sum up to 1000. The probability that you will pick a certain color out of all the seashells is: ((Number of seashells of a certain color)/(Total number of seashells))*100%=The probability that that color will be picked.
Jessique sells handbag for $50 each she spends $4 per handbag for materials and $1000 to rent a store each month write an expression that shows how much profit jessique will earn in 1 month if she sells x amount of handbags
Answers
Answer:
The expression that shows how much profit Jessique will earn in
1 month is ⇒ Profit = 46x - 1000
Step-by-step explanation:
* Lets revise the relation between selling price , cost price and profit
- Profit is the difference between the selling price and the cost price
- Profit = selling price - cost price
- Jessique sells handbag for $50 each
- The selling price of each handbag is $50
- She spends $4 per handbag for materials
- She spends $1000 to rent a store each month
- She sells x amount of handbags in one month
* Lets calculate the cost price of the x handbags in 1 month
∵ She spends $4 per handbag for materials
∴ She spends on the materials of x handbag = 4 × x = 4x
∵ She spends $1000 to rent a store each month
∴ The cost price of x handbags in 1 month = 4x + 1000
∵ She sells x handbags in 1 month
∵ The selling price of 1 handbag is $50
∴ The selling price of x handbags in 1 month = 50 × x = 50x
∵ Profit = selling price - cost price
∴ Profit = 50x - (4x + 1000) ⇒ multiply the bracket by (-)
∴ Profit = 50x - 4x - 1000 ⇒ add like terms
∴ Profit = 46x - 1000
* The expression that shows how much profit Jessique will earn in
1 month is Profit = 46x - 1000
Final answer:
Jessique's profit for selling x handbags in one month is represented by the expression 46x - 1000, where x is the number of handbags sold.
Explanation:
Jessique sells handbags for $50 each. She spends $4 per handbag for materials and $1000 to rent a store each month. To calculate Jessique's profit for selling x handbags in a month, you would subtract both the materials cost and the fixed store rent from her total sales.
The total sales from x handbags is $50 times x, or $50x. The cost of materials for x handbags is $4 times x, or $4x. The fixed store rent is $1000 every month, regardless of how many handbags are sold.
Therefore, to find her profit, the expression is:
Profit = Total Sales - Materials Cost - Fixed Rent
Profit = (50x) - (4x) - 1000
Simplifying this expression, her profit for x handbags in a month would be:
Profit = 46x - 1000

From examining the graph in the "image attached", note that we have a "line" in linear format" ; and that has a "solid line" (as opposed to a "dashed line"); with a "shaded portion" toward one side.
The presence of a "solid line" indicates:
" ≥" {"greater than or equal to"} ; or,
" ≤ " {"less than or equal to"};
________________________________________________________
So we can narrow down our answer choices to:
________________________________________________________
[C]: " y ≤ x − 2 " ; and:
[D]: " y ≥ x − 2 " .
________________________________________________________
Note:
________________________________________________________
A "dashed line" would have narrowed our answers to Choices [A] & [B].
_______________________________________________________
Now, look at inequalities in choices [C] & [D].
Start with Choice: [C]: " y ≤ x − 2 " ;
Now, take the point in the graph: "(0, 0)" ; which is in the shaded portion.
That is; when "x = 0 ; y = 0" .
Does this hold true for the inequality provided for Choice [C]:
→ " y ≤ x − 2 " ?
→ Plug in "0" for "x" ; and "0" for "y" ; and see if the inequality holds true ;
→ " 0 ≤ 0 − 2 " ?

_________________________________________________________
As such, the correct answer is: Answer choice: [D]: " y ≥ x − 2 " .

The distribution property is a property where you simplify an equation or expression by distributing a variable or number outside a set of parenthesis and multiply it inside the parenthesis. It can only be done if the variables inside the parenthesis cannot be further combined.
For example,
2(x + 4)
Since you can't combine the x and the 4 inside the parenthesis, you distribute the 2 into the parenthesis and multiply it by x and 4.
2*x + 2*4
Now, we can just simplify this:

The perimeter of the base of the regular quadrilateral pyramid is P = 30 cm. Find the sum of all edges of this pyramid, if the perimeter of a lateral face is 27.5 cm
Answers
.. 2*(27.5 cm) +(1/2)*(30 cm) = 70 cm
The sum of all edges of the regular quadrilateral pyramid depends on the length of the base edges and the height of the pyramid.
Explanation:To find the sum of all edges of the regular quadrilateral pyramid, we need to find the length of the edges. Let's denote the length of the edge of the base by 'a'. Since the base of the pyramid is a regular quadrilateral, all its sides are equal. Therefore, the perimeter of the base is given by P = 4a = 30 cm.
Dividing both sides of the equation by 4, we get a = 7.5 cm.
Since the perimeter of a lateral face is 27.5 cm, the length of each lateral edge is equal to the height of the pyramid. Therefore, the sum of all edges of the pyramid is 4a + 4h, where 'h' is the height of the pyramid.
So, the sum of all edges is 4(7.5 cm) + 4h = 30 cm + 4h.

After Colby used 3 2/7 buckets out of Anastasia's 10 buckets of mulch, Anastasia has 6 5/7 buckets left. The subtraction was performed by converting mixed numbers to improper fractions, performing the operation, and then converting back to a mixed number.
Anastasia had 10 buckets of mulch for her garden. After Colby used 3 2/7 buckets, we need to subtract that amount from the total to find out how many buckets are left. To subtract the mixed number, we can convert it into an improper fraction and then perform the subtraction.
First, convert 3 2/7 to an improper fraction:
3 2/7 = 3 x 7 + 2 which is 21/7 + 2/7 = 23/7.
Now subtract the improper fraction from the total number of buckets:
10 - 23/7
Change 10 to a fraction with a denominator of 7 to get 70/7.
Subtract the two fractions:
70/7 - 23/7 = (70 - 23) / 7 = 47/7.
Convert the improper fraction back to a mixed number:
47/7 = 6 5/7 (since 47 divided by 7 is 6 with a remainder of 5).
So, Anastasia has 6 5/7 buckets of mulch left.
