If the sales tax is six 3/4% what is the total cost of a $76.01 item
the total cost of a $76.01 item is $81.14 .
Step-by-step explanation:
Here we have , sales tax is six 3/4% . We need to find that what is the total cost of a $76.01 item .Let's find out:
Sales tax is actually the extra money we need to give apart from actual cost of item which is given to government or concerned authority .
Tax is 6(3/4)% of cost price i.e.
[tex]Tax = \frac{cost-price(6\frac{3}{4})}{100}[/tex]
⇒ [tex]Tax = \frac{cost-price(6\frac{3}{4})}{100}[/tex]
⇒ [tex]Tax = \frac{(76.01)(6.75)}{100}[/tex]
⇒ [tex]Tax = \frac{513.06}{100}[/tex]
⇒ [tex]Tax = 5.13[/tex]
So, total cost = $76.01 + $5.13
total cost = $81.14
Therefore, the total cost of a $76.01 item is $81.14 .

The park has a circular track with a radius of 7.6 yds. How many whole yards of fencing would they need to purchase to enclose the track? Use = 3.14
Answer:
48 yards
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=2\pi r[/tex]
we have
[tex]r=7.6\ yd\\\pi=3.14[/tex]
substitute
[tex]C=2(3.14)(7.6)=48\ yd[/tex]
Answer: 48 yards
Step-by-step explanation:
The circumference of a circle can be calculated with the following formula:
[tex]C=2\pi r[/tex]
Where "C" is the circumference of the circle and "r" is the radius of the circle.
In this case you know that the radius of the circular track is the following:
[tex]r=7.6\ yd[/tex]
Knowing tha radius, you can substitute it into the formula (According to the information given in the exercise, you need to use [tex]\pi =3.14[/tex])
[tex]C=2(3.14)(7.6\ yd)[/tex]
Finally, you need to evaluate.
Therefore, you get that the whole yards of fencing that they need to purchase to enclose the track is:
[tex]C\approx48\ yd[/tex]
Kevin will take 4 math tests this term. All of the tests are worth the same number of points. After taking the first 3 tests, his mean test score is 88 points. How many points does he need on his last test to raise his mean test score to 90 points?
Answer:
Kevin needs 96 points on his last test to raise his mean test score to 90 points.
Step-by-step explanation:
we know that
The mean score is the total of all scores divided by the total number of tests.
Let
x_1 ----> the score in the first math test
x_2 ----> the score in the second math test
x_3 ----> the score in the third math test
x_4 ----> the score in the fourth math test
we have
After taking the first 3 tests, his mean test score is 88 points
so
[tex]\frac{x_1+x_2+x_3}{3} =88[/tex]
[tex]x_1+x_2+x_3=264[/tex] ----> equation A
How many points does he need on his last test to raise his mean test score to 90 points?
so
[tex]\frac{x_1+x_2+x_3+x_4}{4} =90[/tex]
[tex]x_1+x_2+x_3+x_4=360[/tex] ----> equation B
substitute equation A in equation B
[tex]264 + x_4 = 360[/tex]
solve for x_4
[tex]x_4 = 360-264[/tex]
[tex]x_4 = 96[/tex]
Therefore
Kevin needs 96 points on his last test to raise his mean test score to 90 points.
What is the image of Q for a dilation with the center (0,0) and a scale factor of 0.5?
A.) (0.5, 2.5)
B.) (2, 10)
C.) (1, 2.5)
D.) (10, 2)
Answer: OPTION A.
Step-by-step explanation:
A dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure before the transformation) have the same shape, but they have different sizes.
In this case you know that the dilation is centered at the origin and the scale factor is:
[tex]k=0.5[/tex]
Therefore, the rule is the following:
[tex]Q(kx,ky)[/tex]
You can identify in the figure attached that the point Q is:
[tex]Q(1,5)[/tex]
Therefore, you must multiply its coordinates by the scale factor 0.5 in order to get its Image Q'. This is:
[tex]Q'=(1*0.5,5*0.5)\\\\Q'=(0.5.2.5)[/tex]
Final answer:
The image of point Q for a dilation with a scale factor of 0.5 and center (0,0) is (option A) (0.5, 2.5).
Explanation:
To find the image of point Q, we need to apply the dilation equation: (x', y') = (k * x, k * y), where (x, y) are the coordinates of the original point and k is the scale factor.
In this case, the center of dilation is (0, 0) and the scale factor is 0.5. So, for point Q which has coordinates (x, y), the image coordinates (x', y') will be:
(x', y') = (0.5 * x, 0.5 * y)
Therefore, the image of point Q will be (option A) (0.5, 2.5).

In triangle abc the length of side ab is 19 inches and the length of bc is 28 inches. What is the length of ac
Without knowing the type of triangle or the values of the angles, we can only provide a possible range of values for side AC of triangle ABC, which is between 9 inches (in case of an acute triangle) and 47 inches (in case of an obtuse or right angled triangle). For accurate calculation, more detail is necessary.
Explanation:The question pertains to determining the length of the side AC in a triangle ABC. Given are the lengths AB and BC so without additional details such as the angle values or the nature of the triangle, we cannot definitively determine the length of side AC. Such a calculation usually requires the use of trigonometric calculations or the Pythagorean theorem which applies only to right triangles. However, we can establish a range for the possible length of side AC.
If the triangle ABC is obtuse or a right triangle with the right angle at point B, the length of AC (AB+BC) could be up to 47 inches (19 inches + 28 inches). On the other hand, if it is an acute triangle, the length of AC (BC-AB) would be a minimum of 9 inches (28 inches - 19 inches). Please provide more details or check if it's a right triangle for a more specific calculation.

2) f(x) = x² **
g(x)= 3x – 2
Find f(g(-4)
Answer:
[tex]f(g( - 4)) = 196[/tex]
Step-by-step explanation:
The functions are;
[tex]f(x) = {x}^{2} [/tex]
and
[tex]g(x) = 3x - 2[/tex]
We want to find
[tex]f(g( - 4))[/tex]
First we find g(-4) to get:
[tex]g( - 4) = 3 \times - 4 - 2[/tex]
[tex]g( - 4) = - 12- 2[/tex]
[tex]g( - 4) = - 14[/tex]
Now
[tex]f(g( - 4)) = f( - 14)[/tex]
This implies that,
[tex]f(g( - 4)) = {( - 14)}^{2} [/tex]
[tex]f(g( - 4)) = {( - 14)} \times - 14[/tex]
[tex]f(g( - 4)) = 196[/tex]

Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to three decimal places where appropriate. If there is no solution, enter NO SOLUTION.)
3 tan(θ) sin(θ) − 2 tan(θ) = 0
Answer:
Note from question, Let K be any integer. Integer = 1
θ = πk
θ = 3.142 * 1
θ = 3.142 in three decimal places
θ = sin⁻¹ (2/3) + 2kπ
θ = sin⁻¹0.667 + 2*1*3.142
θ = 0.718 + 6.284
θ = 7.002 in three decimal places
∴ 7.002 , 3.142
Step-by-step explanation:
Considering the equation
3 tan(θ) sin(θ) − 2 tan(θ) = 0
The objective is to solve the equation.
First solve the equation in one period.
3 tan(θ) sin(θ) − 2 tan(θ) = 0
( 3sinθ − 2 ) tanθ = 0
Therefore, 3sinθ − 2 = 0 also tanθ = 0
=> sinθ = 2/3 , tanθ = 0
Pick the right equation.
tanθ = 0
θ = tan⁻¹ 0
θ = 0
Using the unit circle, the period of tangent functions is π
Then the general solution of the equation is θ = 0 + πk ==> θ = πk
Pick the left equation.
3sinθ − 2 = 0
3sinθ = 2
sinθ = 2/3
θ = sin⁻¹ (2/3)
As the sine function has period 2π
Then the general solution is θ = sin⁻¹ (2/3) + 2kπ

Reflection
Rotation
Dilation
None of above
The type of transformation that moves P (3,-7) to P'' (3,7) is a reflection. The point has been flipped over the x-axis.
Explanation:The type of transformation which moves point
P (3,-7)
to
P'' (3,7)
is a
reflection
. It appears that point P has simply been flipped over the x-axis. The x-coordinate remains unchanged at 3, but the y-coordinate has been reflected to the opposite side of the x-axis, changing it from -7 to 7. So, a reflection over the x-axis is the correct transformation in this case. The transformation that moves point P (3,-7) to P'' (3,7) is a reflection over the x-axis. When a point is reflected in the x-axis, the y-coordinate changes sign while the x-coordinate remains the same. In this case, when the y-coordinate of P changes from -7 to 7, it means that P was reflected over the x-axis.

8. Chicago, Illinois, has a longitude of 88°W and a latitude of 42°N.
Indianapolis, Indiana, is located at 86°W and 40°N. At this longitude/latitude,
each degree is about 53 miles. Find the distance between Chicago and
Indianapolis.
Chicago, IL
Indianapolis, IN
Lesson 7 Distance on the Coordinate Plane
435
Answer: 150 miles
Step-by-step explanation:
The distance between Chicago and Indianapolis is approximately 150 miles.
To find the distance between Chicago and Indianapolis using their latitude and longitude coordinates, we can apply the Pythagorean theorem. The distance between two points on the Earth's surface can be approximated by considering the Earth as a flat plane, which is reasonable for relatively short distances like the one between these two cities.
The difference in latitude (north-south distance) between Chicago and Indianapolis is:
[tex]\[ 42N - 40N = 2N \][/tex]
The difference in longitude (east-west distance) between the two cities is [tex]\[ 86W - 88W = 2W \][/tex]
Since each degree is approximately 53 miles, we can calculate the north-south distance and the east-west distance:
North-south distance in miles:
[tex]\[ 2N \times 53 \text{ miles/degree} = 106 \text{ miles} \][/tex]
East-west distance in miles:
[tex]\[ 2W \times 53 \text{ miles/degree} = 106 \text{ miles} \][/tex]
Now, we can use the Pythagorean theorem to find the straight-line distance (the hypotenuse of the right triangle formed by the north-south and east-west distances):
Let [tex]\( d \)[/tex] be the distance between the two cities, then:
[tex]\[ d^2 = (106 \text{ miles})^2 + (106 \text{ miles})^2 \] \\[/tex]
[tex]\[ d^2 = 11236 \text{ miles}^2 + 11236 \text{ miles}^2 \] \\[/tex]
[tex]\[ d^2 = 22472 \text{ miles}^2 \] \\[/tex]
[tex]\[ d = \sqrt{22472 \text{ miles}^2} \] \\[/tex]
[tex]\[ d \approx 150 \text{ miles} \][/tex]
