Jennelle went shopping for school clothes. She spent $137 at one store and $96 at another store. She had $87 left.
How much money did Jennelle take shopping?
Answer:
Jennelle actually brought 320$
Step-by-step explanation:
She spend on first store 137$
2nd store 96
she left 87 which is after he spend the money in the stores
so you add 137$ and 96$ to get 233 then usually this kind of question asks about how much he left. But it already gave us how much she left
so if you add it you will find out how much he brought to the shopping
so 233+87 is equal to 320 $

Answer:
X + P = 34
330X + 250P = 9620
Step-by-step explanation:
The question tells us that there were 34 consoles sold. Therefore, we can draw the straight forward conclusion that whatever combination of consoles were sold, the number Xboxes (X) and PS4s (P) sold together has to be 34 in total. Thus:
X + P = 34
Now, we know the each Xbox sold for $330, and each PS4 sold for $250, and the total sales from the consoles bought was $9620. Thus:
$330X + $250P = $9620

David bought 9 t-shirts for $36. The store charges a 6.5% sales tax on the total cost. What will be the
total cost of the shirts, including tax?
Answer:
In order to calculate the sales tax of an item, we need to first multiply the pre-tax cost of the item by the sales tax percentage after it has been converted into a decimal. Once the sales tax has been calculated it needs to be added to the pre-tax value in order to find the total cost of the item. Let's start by working with an example. If a magazine costs $2.35 and has a 6% sales tax, then what is the total cost of the item. First, we need to convert the sales tax percentage into a decimal by moving the point two spaces to the left.
6%→0.06
Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.
\textup{Sales tax}=0.06\times\$2.35
\textup{Sales tax}=\$0.141
Round to two decimal places since our total is in dollars and cents.
\textup{Sales tax}=\$0.14
Last, add this value to the pre-tax value of the item to find the total cost.
\textup{Total cost}=\textup{Pre-tax value}+\textup{Sales tax}
\textup{Total cost}=\$2.35+\$0.14
\textup{Total cost}=\$2.49
Step-by-step explanation:
Total cost of 9 t-shirts = $36
Percentage of tax on the total cost = 6.5%
Tax on the total cost :
[tex]= 6.5\% \: of \: \: 36[/tex]
[tex] = \frac{6.5 \times 36}{100}[/tex]
[tex] = \frac{234}{100} [/tex]
[tex] = \color{hotpink}\$ \: 2.34[/tex]
Thus, the total tax on the shirts = $2.34
Total cost of the shirts including tax :
[tex] = 36 + 2.34[/tex]
[tex] =\color{hotpink} \bold{\$ \: \: 38.34}[/tex]
Therefore, the total cost of the shirts including tax = $38.34

The angle of elevation to the top of a particular skyscraper in New York is found to be 12 degrees from the ground at a distance of 1.3 mi from the base of the building. Using this information, find the height of the skyscraper. * 20 points a. 1560 ft b. 2918 ft c. 1459 ft
Answer:
The height of the skyscraper is 1,459 ft. Choice c
Step-by-step explanation:
Right Triangles
The ground and the building form a right angle (90°). In the right triangles, the trigonometric ratios are satisfied. To solve the problem we use the tangent ratio, defined as:
[tex]\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}[/tex]
The angle of elevation from which the skyscraper can be seen is θ=12°. The opposite side of this angle is the height of the skyscraper H and the adjacent side is the distance from the ground X=1.3 miles.
Converting miles to feet: X=1.3*5,280 = 6,864 ft
Applying the tangent ratio to the angle of elevation:
[tex]\displaystyle \tan 12^\circ=\frac{H}{6,864}[/tex]
Solving for H:
[tex]H=6,864\tan 12^\circ[/tex]
Calculating:
H = 1,459 ft
The height of the skyscraper is 1,459 ft. Choice c

One pound is equal to 0.454 kilogram. If Jim has a mass of 50 kilograms, write an equation to represent how many pounds p he weighs
Answer:22.6796
Step-by-step explanation:
for an approximate result, divide the mass value by 2.205
The equation to convert kilograms to pounds is p = 22.7 pounds if Jim has a mass of 50 kilograms.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We know that one pound is equal to 0.454 kilograms, so we can write the conversion factor as:
1 pound = 0.454 kilograms
To convert a mass in kilograms to a mass in pounds, we'll multiply the mass in kilograms by the conversion factor.
So, the equation to convert kilograms to pounds is:
p = 0.454 × kg
To find the number of pounds that Jim weighs, we'll substitute his mass of 50 kilograms into the equation:
p = 0.454 × 50
p = 22.7 pounds
Therefore, Jim weighs 22.7 pounds.

Which Point of Concurrency is NOT always inside a triangle?* A:Centroid
B:Incenter
C:Circumcenter
Circumcenter Point of Concurrency is NOT always inside a triangle. Hence, option (C) is correct.
What are Centroid, Incenter and Circumcenter of triangle?The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.
The intersection of the three interior angle bisectors of a triangle forms the triangle's incenter. Due to the junction point of the central axis being the center of the inscribed circle of the triangle, this point is equally spaced from each of its sides.
The intersection of all of the triangle's sides' perpendicular bisectors—that is, the lines that are perpendicular to each side's midpoint—indicates the location of the triangle's circumcenter.
