What is the approximate surface area of the cone?
Responses
94.2 in²
103.6 in²
131.9 in²
257.5 in²
The approximate surface area of the cone is equal to: B. 103.6 in².
How to calculate surface area of a cone?Mathematically, the surface area (SA) of a cone can be calculated by using this mathematical expression:
Surface area (SA) of a cone = πr(l + r)
Where:
l represents the slant height of the cone.r represents the radius of the cone.Note: Radius = diameter/2 = 6/2 = 3 inches.
Substituting the given parameters into the surface area (SA) of a cone formula, we have the following;
Surface area (SA) of a cone = πr(l + r)
Surface area (SA) of a cone = 3.14 × 3(8 + 3)
Surface area (SA) of a cone = 3.14 × 3(11)

The owner of the theater in
Item 18 wants to make at least
$400 at each performance. Let x be
the number of adult tickets and y
be the number of child tickets sold.
Write an inequality to show the
number of tickets that need to
be sold
An inequality to show the number of tickets that need to be sold is;
x + y ≥ $400
How to solve Inequality Word Problems?
Inequality is simply defined as the comparison and boundary for two non equal values. Thus, we can easily say that inequality compares the values that are non equal.
We are told that the owner wants to make $400 and sets boundary that;
The least amount to make = $400
The highest amount to make = infinite
This introduces relation in inequality as $400 or greater than $400.
Therefore the money made is counted as a combination from child tickets and adult tickets. If x is the amount that is made made through child tickets and y is the amount made from the adults, then we have;
x + y ≥ $400

e they are made of semi circles,quater circles and square for each shape fins area and perimeter .give your answer as a completely simplified
The the area and perimeter of the shapes in terms of pi are 36pi - 72.
What is Perimeter?You should understand that the perimeter of the object is the distance round the object.
A circle's area is calculated as pi*r², so a semicircle is pi*r² / 2, and a quarter circle is pi*r² / 4.
A triangle's area is 0.5*base*height.
We have a quarter circle of radius 12, of which the area is pi*(12² / 4) = 36pi.
The area of the triangle ABC is 0.5*12*12 = 72,
This means that the shaded area is 36pi - 72.
Rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of AD is actually identical in area to the blank semicircle-shaped space to the left of BC.
So if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. The area of a square is s² = 24² = 676 cm².

Which of the following inequalities matches the graph ?
Option A is correct.
The given line has a slope of 5 which can be calculated by counting the change in the y-direction with respect to the change in the x-direction from the graph. And the y-intercept is -1
The equation of the line is,
y=5x-1 or

7.4x+3-9= 6 + 7.4x
with solution please
Answer:
6
Step-by-step explanation:
Solution for 7.4x+3-9=6+7.4x equation:
Simplifying
7.4x + 3 + -9 = 6 + 7.4x
Reorder the terms:
3 + -9 + 7.4x = 6 + 7.4x
Combine like terms: 3 + -9 = -6
-6 + 7.4x = 6 + 7.4x
Add '-7.4x' to each side of the equation.
-6 + 7.4x + -7.4x = 6 + 7.4x + -7.4x
Combine like terms: 7.4x + -7.4x = 0.0
-6 + 0.0 = 6 + 7.4x + -7.4x
-6 = 6 + 7.4x + -7.4x
Combine like terms: 7.4x + -7.4x = 0.0
-6 = 6 + 0.0
-6 = 6
Solving
-6 = 6

What are properties of Equality ?Addition, subtraction, multiplication, division, reflexive, symmetric, transitive, substitution, and square root qualities are the main nine properties of equality. Algebraic equations involving real numbers can be resolved with the aid of the addition, subtraction, multiplication, and division characteristics of equality.
When the same quantity is added to both sides of an equation, the equation still holds true, according to the definition of the addition property of equality. This condition may be formally expressed as follows: for real numbers a, b, and c, if a = b, then a + c = b + c. Equations involving algebra and arithmetic can both leverage this characteristic.

The slope of the line made by these given coordinates is 7/6.
What is proportionality?In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.
Given coordinates of a graph. Since the coordinates are proportional thus, these coordinates represent the graph of the line as shown in the figure below.
From the general formula of the slope of the line (m) = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
The slope of the line = (14-7) / (12- 6)
The slope of the line = 7/6

Write an exponential decay function to model the situation. Compare the average rates of change over the given intervals.
initial value: 42
decay factor: 0.7
1
Answer: An exponential decay function models a situation in which a value decreases over time at a rate that is proportional to its current value. The function has the form:
y = A*e^(-kt)
Where y is the final value, A is the initial value, e is the base of the natural logarithm (approximately 2.718), k is the decay factor, and t is the time.
In this case, the initial value is 42 and the decay factor is 0.7. So the exponential decay function that models the situation is:
y = 42 * e^(-0.7t)
To compare the average rates of change over the given intervals, we need to find the derivative of the function, which represents the instantaneous rate of change of the function at any given point in time.
The derivative of this function is:
dy/dt = -0.742e^(-0.7t)
The negative sign indicates that the value is decreasing over time. The absolute value of the derivative will be the rate of decay.
So, the average rate of change over the given intervals is -0.7*42 which is -29.4
The rate of decay is always -29.4 for this function.

. Tara's meal cost $8.60. She had to pay a sales tax of 6%. Then she left a 10% tip based off the new total. What did she spend altogether?
Answer:
The answer is $10
Step-by-step explanation:
GivenTara's meal cost $8.60. She had to pay a sales tax of 6%.It means she paid tax of $8.60 which is 6%
So,
(8.60 × 6) ÷ 100
51.6/100 = $0.516
Here, The tax was $0.516
Total cost of meal
= $0.516 + $8.60 = $9.116 (including tax)
Then she left a 10% tip based on the new total.(9.116 × 10) ÷ 100 = $0.9116
Total cost (including tip)
= $9.116 + $0.9116 = $10.0276 ≈ $10
Thus, Tara spend $10 altogether.

The measure of one angle of a right triangle is 24∘ more than the measure of the smallest angle. Find the measure of the smallest angle.
33°
Since it's a right triangle that has an immediate 90° angle, we have 90°'s left to worry about. We have two angles to worry about it, and since one angle is bigger than the other by 24°, it means that the gap between them is 24°. After doing some mental math, you get 57° + 33°. The gap between them is 24°, and they add up to 90°. Finally, since you're looking for the smaller angle in this problem, then 33° would be your answer.

There are an improper fraction of 29/20 ounces or a mixed fraction of one whole number and a fraction of 1/20 ounces in the mixture.
How to calculate for the fraction of ouncesWe shall add the two fractions 4/5 and 13/20, but firstly we find the lowest common multiple (LCM) of their denominators to enable us get a single denominator before simplifying the numerator.
LCM of 2 and 20 is equal to 20
20/5 = 4 and 20/20 = 1
4/5 + 13/20 = (4×4 + 1×13)/20
4/5 + 13/20 = (16 + 13)/20
(4/5 + 13/20) ounces = 29/20 ounces
Therefore, 29/20 is an improper fraction gotten by adding the fraction of ounces, but when expressed as mixed fraction is one whole number, and a fraction 1/20 ounces in the mixture.
