The sales tax on a $44.00 purchase is $2.42. At this rate, what would be the tax on goods worth $60.00?
Answer:
We can use proportions to find out the tax on goods worth $60.00:
Let x be the tax on goods worth $60.00.
Then, we can set up the following proportion:
tax/sales = tax rate
or
2.42/44 = x/60
To solve for x, we can cross-multiply and simplify:
44x = 2.42 * 60
44x = 145.20
x = 145.20/44
x = 3.3 (rounded to the nearest cent)
Therefore, the tax on goods worth $60.00 would be $3.30.
Step-by-step explanation:
Find x.

Answer: 42
Step-by-step explanation:
We start by looking at the 49 degree angle. A common method of solving geometric problems is to bring things together. To follow this concept, we can say that the 49 degree angle has a vertical angle inside the triangle, which means that angle is 49 degrees. We now work with the 91 degree angle. We can see the 91 degree angle falls on a line, so the other side of the angle equals 180-91=89. All angles in a triangle add up to 180 degrees, so x + 49 + 89 = 180, so x=180 - 138 = 42.

The surface area of the cone is 1,966.896 mm²
How to find the surface area of the cone?We can see that the surface area of a cone of slant height H and radius R is:
SA = pi*R² + pi*R*H
Here we can see that R = 27mm/2 = 13.5mm
And H = 32.9 mm
And we know that pi = 3.14
So, replacing that we will get:
SA = 3.14*(13.5mm)² + 3.14*13.5mm*32.9mm
SA = 1,966.896 mm²

Consider the following formulas.
a sin Bθ + b cos Bθ = a2 + b2 sin(Bθ + C), where C = arctan(b/a) and a > 0
a sin Bθ + b cos Bθ = a2 + b2 cos(Bθ − C), where C = arctan(a/b) and b > 0
Use the formulas given above to write the trigonometric expression in the form a sin Bθ + b cos Bθ.
11 cos (θ − π/ 4)
The trigonometric expression 11 cos (θ − π/4) in the form a sin Bθ + b cos Bθ is 11/√2 cos θ.
What is the trigonometric expression?
The write the trigonometric expression in the required, we can start by using the second formula:
a sin Bθ + b cos Bθ = a^2 + b^2 cos(Bθ − C)
where;
C = arctan(a/b) and b > 0Let a = 11 and b = 11/√2, and Bθ = θ − π/4.
Then C = arctan(a/b) = arctan(11/(11/√2)) = arctan(√2).
Substituting these values, we get:
11 cos (θ − π/4) = 11/√2 cos (θ − π/4 + arctan(√2))
= 11/√2 cos (θ - π/4 + π/4)
= 11/√2 cos θ

Would a yardstick be a reeasonable tool to use to measure the length of a canoe paddle explain
In conclusion, a yardstick or ruler can be a reasonable tool to use to measure the length of a canoe paddle.
Then, move the yardstick along the length of the paddle, counting the marks until you reach the other end. This will give you an estimate of the length of the paddle in terms of the number of yardstick marks.
For a more precise measurement, you can also use a ruler. Place the zero mark of the ruler at the tip of the paddle and move the ruler along the length of the paddle, counting the small marks that correspond to 1/16th of an inch. This will give you a more precise estimate of the length of the paddle.

In a class, we have 61 students of different majors. There are 23 chemistry majors (C), 12 math majors (M), 9 engineering majors (E), and 17 students who are undecided (U). Of these students, 4 of them have declared both math and engineering majors. A student will randomly be chosen to win a scholarship. Find the probability of awarding the scholarship to a student who is either a math major or an engineering major. 0.0290 0.7213 0.2787 0.3443
The probability of awarding the scholarship to a student who is either a math major or an engineering major is 0.2787 .Option (c) is the correct answer.
In this question, we are asked to find the probability of awarding the scholarship to a student who is either a math major or an engineering major. Total students (n) = 61 Chemistry majors (C) = 23 Math majors (M) = 12 Engineering majors (E) = 9 Undecided (U) = 17Students with declared majors in Math and Engineering (M ∩ E) = 4
We have to find P(A) = P(student is either a math major or an engineering major).To solve this problem, we will use the addition rule of probability. The addition rule states that the probability of event A or B occurring equals the probability of event A plus the probability of event B minus the probability of both A and B occurring. P(A) = P(M ∪ E) = P(M) + P(E) - P(M ∩ E)
Here, P(M) = probability that the student is a math major= number of math majors / total students = 12/61 P(E) = probability that the student is an engineering major= number of engineering majors / total students = 9/61 P(M ∩ E) = probability that the student has declared both math and engineering majors = 4/61So,P(A) = P(M ∪ E) = P(M) + P(E) - P(M ∩ E)P(A) = 12/61 + 9/61 - 4/61= 17/61≈ 0.2787

A wide receiver catches a ball and begins to run for the endzone following a path defined by (x-5, y-50) = t(0,10). A defensive player chases the receiver as soon as he starts running following a path defined by (x-10, y-54) = t(-0. 9, -10. 72)
Write Parametric equations for the path of each player.
A. Receiver: x=50,y=5-10t
Defensive: x=10-0. 9t, y=54-10. 72
B. Receiver: x=5, y=50-10t
Defensive: x=10-0. 9t, y=54-10. 72t
C. Receiver: x=5, y=50-10t
Defensive: x=54-10. 72t, y=10-0. 9t
D. Receiver: x=10-0. 9t, y=54-10. 72t
Defensive: x=5, y=50-10t
The correct answer is B Parametric equations for the path of each player is Receiver: x=5, y=50-10t Defensive: x=10-0. 9t, y=54-10. 72t
The given paths of the receiver and defensive player can be described parametrically, using the parameter t, as:
Receiver: x = 5, y = 50 - 10t
Defensive: x = 10 - 0.9t, y = 54 - 10.72t
We can use the parameter t to represent the time that has elapsed since they started moving. The parametric equations describe the x and y coordinates of each player as functions of t.
By plugging in different values of t, we can determine the positions of the players at different points in time. In this case, the receiver moves horizontally while the defensive player moves at an angle, so their equations are different.

The statements that is true is option C FG ⊥ HB and FG ║ DE, that is FG is perpendicular to HB and parallel to DE.
What are perpendicular and parallel lines?Geometry's use of parallel and perpendicular lines is crucial, and their distinctive qualities make it simple to distinguish between them. If two lines are in the same plane, are spaced equally apart, and never cross one another, they are said to be parallel. Perpendicular lines are those that cross at an angle of 90 degrees. Two straight lines are said to be parallel if they are located in the same plane and never cross one another. On the other hand, two lines are said to be perpendicular when they cross each other at a 90° angle.
From the given figure we observe that, the angle between the segments FG and HB is 90 degrees thus,
FG ⊥ HB.
Also, DE ⊥ HB, thus the segments FG ║ DE.
Hence, the statements that is true is option C FG ⊥ HB and FG ║ DE, that is FG is perpendicular to HB and parallel to DE.

In September 1998 the population of the country of West Goma in millions was modeled by f(x)=17.9e0.002x. At the same time the population of East Goma in millions was modeled by g(x)=13.6e0.017x. In both formulas x is the year, where x=0 corresponds to September 1998. Assuming these trends continue, estimate what the population will be when the populations are equal.A. 19 millionB. 18 millionC. 17 millionD. 1 million
Option B, 18 million, is the answer to this question.
In September 1998, the population of West Goma in millions was modeled by the function f(x) = 17.9e0.002x, and the population of East Goma in millions was modeled by the function g(x) = 13.6e0.017x. Here, x represents the year, with x=0 corresponding to September 1998.
To find out the point of intersection where the populations are equal, we equate both formulas and solve for x:
17.9e0.002x = 13.6e0.017x
Taking the natural logarithm of both sides of the equation gives:
x ln(17.9) + 0.002x = x ln(13.6) + 0.017x
Simplifying and rearranging terms, we get:
ln(17.9) - ln(13.6) = (0.017 - 0.002)x
0.079 = 0.015x
Solving for x, we get:
x = 5.27 years
Since x is the year, when x = 5.27, it corresponds to the year 1998 + 5.27 ≈ 2003.
When the populations are equal, the population will be f(5.27) ≈ 18 million for West Goma.
