If you have an item that costs 10 dollars and a sales tax of 7% you could do it this way
10 * 7/100 = 0.70 dollars.
The total cost is 10.70 dollars. or 10 dollars and 70 cents.
The best way to do the total however is to multiply the cost by 1.07. You will get the number the customer has to pay.
10 * 1.07 = 10.70
So for any price (p) it would be 1.07*p
Answer:
1.07p
Step-by-step explanation:
The tax equals the price times the tax rate
We know the price p and the tax rate 7%
tax = p*7%
Changing this to decimal form
tax = .07p
The final price of the item is the sales tax plus the price
final price = tax + price
.07p +p
1.07p
Using the equation, y=10000(0.97)x predict the purchasing power of $10000 ten years later
Answer:
The purchasing power is $7374
Step-by-step explanation:
We are given an equation [tex]y=10000(0.97)^x[/tex]
where,
y represents purchasing power.
x represents the number of years.
We need to find purchasing power of $10000 after 10 years.
Put x=10 into equation and solve for y
[tex]y=10000(0.97)^{10}[/tex]
[tex]y=7374.24\approx 7374[/tex]
After 10 years the purchasing power of $10000 becomes $7374
As we can see the value of the product decrease.
Hence, The purchasing power is $7374

The expression 17n+11 represents the perimeter of the triangle.
A simplified expression that represents the measure of the third side is
Answer: the answer is 8n
The third side of a triangle whose perimeter is 17n + 11 and the other two sides are (5n + 6) and (4n + 6) is 8n
The perimeter of any shape is total distance around the shape
In the triangle shown:
The perimeter = 17n + 11
The first side = 5n + 6
The second side = 4n + 5
Let the third side be represented by M
The perimeter = (The first side) + (The second side) + (The third side)
Substitute perimeter = 17n + 11, first side = 5n + 6, second side = 4n + 5, and third side = M into the equation above
17n + 11 = (5n + 6) + (4n + 5) + M
M = 17n + 11 - 5n - 6 - 4n - 5
Collect like terms
M = 17n - 5n - 4n + 11 - 6 - 5
M = 8n
Therefore, the third side of a triangle whose perimeter is 17n + 11 and the other two sides are (5n + 6) and (4n + 6) is 8n

Math help!! 5 questions!!! A classmate believes that a triangle can have both right angle and an obtuse angle. Which of the following statements would you use to convince him that he is incorrect. A. Its is not possible because the sum of the angles in the triangle can't exceed 180 d. B. It is not possible because if a triangle has an obtuse triangle , that means all the angles are obtuse angles. C. It is not possible because if a triangle has a right triangle, that means all the angles are right angles. Its is possible. The classmate is correct.
Final answer:
A triangle cannot have both a right angle and an obtuse angle, as the sum of its angles must always equal 180 degrees.
Explanation:
To convince your classmate that a triangle cannot have both a right angle and an obtuse angle, you should explain that according to Euclidean geometry, the sum of the angles in any triangle must equal two right angles, or 180 degrees.
If a triangle has a right angle (90 degrees), then the remaining two angles must sum up to 90 degrees as well. Introducing an obtuse angle, which is any angle greater than 90 degrees, would cause the total sum of the angles to exceed 180 degrees, which is impossible.
Therefore, the correct statement to use would be 'A. It is not possible because the sum of the angles in the triangle can't exceed 180 degrees.'

Step-by-step explanation:
Caitlin says that AC is the longest segment of fencing becasue it is opposite 68 degrees, the largest angle measure in the figure. Is her reasoning valid?
Caitlin's reasoning is valid; in a triangle, the side opposite the largest angle is indeed the longest, according to the triangle inequality theorem.
Explanation:Caitlin's reasoning that AC is the longest segment of fencing because it is opposite the largest angle measure in the figure is indeed valid. In any triangle, the longest side is always opposite the largest angle. This is due to the fact that the angles in a triangle are directly related to the lengths of their opposite sides.
The triangle side opposite the largest angle is the longest because of the triangle inequality theorem. So, if 68 degrees is the largest angle in the triangular piece of land that Caitlin is fencing, then segment AC, being opposite this angle, would be the longest side.
Caitlin's reasoning is valid based on the principle that in a triangle, the longest side is opposite the largest angle. The length of the third side can be determined using the cosine law or vector addition, depending on the given details.
Explanation:The validity of Caitlin's reasoning is based on a principle in geometry that states the side opposite the largest angle in a triangle is the longest side. This fact is drawn from the Law of Sines which asserts that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. Therefore, if AC is indeed opposite the largest angle, which is 68 degrees, then her reasoning is valid and AC would be the longest segment of fencing.
To calculate the length of the third side, one can use the cosine law or the vector addition method depending on the given information and the context of the question. If the internal angles and lengths of two sides are known, the cosine law allows for the calculation of the third side. In the context of vectors, the resultant vector, which in this case is the third side C, can be calculated by mathematically adding vectors A and B.

The figure is made up of 2 rectangles and 2 right triangles.
What is the area of the figure?
A > 173 units^2
B > 253 units^2
C > 277 units^2
D > 325 units^2
QUESTION 1
The area of a triangle is given by
[tex]Area=\frac{1}{2}\times base\times heigth[/tex]
The length of the base of the triangle is [tex]6\:in.[/tex] and the vertical height is [tex]8\:in.[/tex].
We substitute these values into the formula to obtain,
[tex]Area=\frac{1}{2}\times 6\times 8[/tex]
[tex]Area=3\times 8[/tex]
[tex]Area=24\:in^2[/tex]
The area of the triangle is 24 square inches.
The correct answer is A
QUESTION 2
The company logo is made up of three triangles and a square.
The length of the square is [tex]7\:cm[/tex]
The area of a square is given by
[tex]Area=l^2[/tex]
[tex]\Rightarrow Area=7^2[/tex]
[tex]\Rightarrow Area=49cm^2[/tex].
The area of one of the triangles is
[tex]Area=\frac{1}{2}\times base \times height[/tex]
The height of the triangle is [tex]4cm[/tex].
The base of the triangle is on one side of the square, so it is [tex]7cm[/tex].
The area now becomes
[tex]Area=\frac{1}{2}\times 7 \times 4[/tex]
[tex]\Rightarrow Area=7 \times 2[/tex]
[tex]\Rightarrow Area=14cm^2[/tex].
Since there are three identical triangles, we multiply the area of one triangle by 3 to get area of the three triangles.
[tex]Area\:of\:the\:three\:triangles=3\times14=42cm^2[/tex]
The area of the logo is equal to the area of the square plus the area of the three identical triangles.
[tex]Area\:of\:logo=49+42=91cm^2[/tex]
Hence the area of the logo is [tex]91cm^2[/tex]
QUESTION 3
Since the figure is made up of two rectangles and two right triangles, we find their areas and sum them to get the area of the figure.
The area of a rectangle is given by
[tex]Area=l\times w[/tex]
The width of the bigger rectangle is [tex]5[/tex] and the length is [tex]25[/tex].
[tex]Area\:of\:bigger\: rectangle=25\times 5[/tex]
[tex]Area\:of\:bigger\: rectangle=125\:square\:units[/tex]
The width of the smaller rectangle is [tex]8[/tex].
The length of the smaller rectangle is [tex]25-(6+6)=25-12=13[/tex].
[tex]Area\:of\:smaller\: rectangle=13\times 8[/tex]
[tex]Area\:of\:smaller\: rectangle=104\:square\:units[/tex].
The two triangles are identical, so we find the area of one and multiply by 2
[tex]Area\:of\:triangle=\frac{1}{2}\times base \times heigth[/tex]
[tex]Area\:of\:triangle=\frac{1}{2}\times 6 \times 8[/tex]
[tex]Area\:of\:triangle=3 \times 8[/tex]
[tex]Area\:of\:triangle=24\:square\:units[/tex]
[tex]\Rightarrow Area\:of\:the\:two\:triangles=2\times24=48\:square\:units[/tex]
The area of the figure is
[tex]=125+104+48=277\:sqaure\:units[/tex]
The correct answer is C
If I=prt, which equation is equivalent to t?
5. What is the value of x to the nearest tenth? The figure is not drawn to scale.
A) x=15.7
B) x=4.4
C) x=13.9
D) x=1.9
The correct option is B) [tex]x=4.4[/tex]. The value of x to the nearest tenth is x=4.4.
To find the value of x, we need to apply the Law of Cosines to the given triangle. The Law of Cosines states that for any triangle with sides [tex]\( a \), \( b \), and \( c \),[/tex] and the angle opposite side c and [tex]\( \gamma \),[/tex] the following relationship holds: [tex]\[ c^2 = a^2 + b^2 - 2ab\cos(\gamma) \][/tex]
Let's denote the sides of the triangle as follows: the side opposite the right angle (hypotenuse) as c, the side opposite the 30-degree angle as b, and the side opposite the 60-degree angle as a. We are given that [tex]\( a = 2x \), \( b = x \), and \( c = 10 \).[/tex]
Using the Pythagorean theorem, we have:
[tex]\[ c^2 = a^2 + b^2 \][/tex]
[tex]\[ 10^2 = (2x)^2 + x^2 \][/tex]
[tex]\[ 100 = 4x^2 + x^2 \][/tex]
[tex]\[ 100 = 5x^2 \][/tex]
[tex]\[ x^2 = \frac{100}{5} \][/tex]
[tex]\[ x^2 = 20 \][/tex]
[tex]\[ x = \sqrt{20} \][/tex]
[tex]\[ x = \sqrt{4 \cdot 5} \][/tex]
[tex]\[ x = 2\sqrt{5} \][/tex]
Now, we calculate the numerical value of x:
[tex]\[ x \approx 2 \cdot 2.236 \][/tex]
[tex]\[ x \approx 4.472 \][/tex]
Rounding to the nearest tenth, we get: [tex]\[ x \approx 4.4 \][/tex]
Therefore, the value of x to the nearest tenth is 4.4, which corresponds to option B.

You observe one pine tree. if the probability of not being a foxtail pine is equal to 0.06, what is the probability that this tree is a foxtail pine? (calculate to 2 decimals)
Final answer:
The probability that the observed pine tree is a foxtail pine is 0.94 or 94%, calculated by subtracting the probability of it not being a foxtail pine (0.06) from 1.
Explanation:
If the probability of not being a foxtail pine is 0.06, we can find the probability of a tree being a foxtail pine by subtracting this from 1 (since the sum of all probabilities for an event and its complement must equal 1). Therefore, the calculation to find the probability of the tree being a foxtail pine is 1 - 0.06.
Carrying out this subtraction gives us:
1 - 0.06 = 0.94.
Thus, the probability that the observed pine tree is a foxtail pine is 0.94, or 94%, when calculated to two decimals.
