Find the surface area of the cone represented by the net below.
31.4 in.2
43.96 in.2
394.38 in.2
56.52 in.2
Answer:
43.96 in^2
Step-by-step explanation:
The net shows the areas of the parts of the cone, so you simply need to add them up to get the total surface area.
31.4 in^2 +12.56 in^2 = 43.96 in^2
Answer:
43.96 in.2.
Step-by-step explanation:
The surface area of a cone is the triangular shape and its circular base.
In this case, the top of the cone is 31.4 inches squared in area, and the circular base is 12.56 inches squared.
So, the surface area of the cone is 31.4 + 12.56 = 43.96 inches squared.

The state fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 13 vans and 9 buses with 569 students. High School B rented and filled 14 vans and 3 buses with 325 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
Answer:
The number of students in each van = 14
The number of students in each bus = 43
Step-by-step explanation:
Let the number of students that can fill a van be v.
Let the number of students that can fill a bus be b.
The senior class at High School A rented and filled 13 vans and 9 buses with 569 students.
13 vans will have (13v) students
9 buses will have (9b) students
13v + 9b = 569
High School B rented and filled 14 vans and 3 buses with 325 students
14 vans will have (14v) students.
3 buses will have (3b) students.
14v + 3b = 325
Combining these two simultaneous equations
13v + 9b = 569
14v + 3b = 325
Solving simultaneously,
v = 14 students.
b = 43 students.

Chad washes windows after school to make some extra money. He charges $5.50 to wash each window. If the customer provides the supplies, Chad deducts $3.25 from the total cost. One customer paid a total of $27.50 and did not provide supplies. Which equation could be used to find the number of windows, w , that Chad washed for this customer? A) 5.5 w + 3.25 = 27.5 B) 5.5 w - 3.25 = 27.5 C) 5.5 w = 27.5 D) 5.5 - 3.25 w = 27.5
Answer:
C. 5.5 = 27.5
Step-by-step explanation:
The customer did not provide any supplies which means that the number 3.25 should not even be apart of the answer choice because it is not being deducted.
5.50 multiplied by how many widows (w) are washed should equal 27.50
Therefore C. 5.5 = 27.5 is the answer
Answer:
C) 5.5 w = 27.5

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
A. If the total is 25$, then each value meal would equal 25/5 = 5$, which is reasonable.
B. If the total is $1000, then each meal would equal 1000/5 = $200, which is not reasonable
C. If the total is $100, then each meal would equal 100/5 = $20, which is not a reasonable price for a value meal
D. If the total is $10, then each meal would equal 10/5 = $2 which is not a reasonable price for a value meal.
Hence, If the total is 25$, then each value meal would equal 25/5 = 5$, which is reasonable. so option A is correct.

A normal distribution has a mean of 60 and a standard deviation of 2. Determine the z-
score for the data value of 22.
Answer: z score is -19
Work Shown:
x = 22 is the raw score
mu = 60 is the mean
sigma = 2 is the standard deviation
z = (x-mu)/sigma = formula to find z scores
z = (22 - 60)/2
z = -38/2
z = -19
The z score of -19 means we are 19 standard deviations below the mean. Anything beyond 3 standard deviations is often considered unusual/rare as most of the data in the normal distribution is within 3 standard deviations (approximately 99.7% of the distribution)

Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;
[tex]Difference = 1.7 - (-1/2)[/tex]
Then, we calculate the distance;
In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;
Hence,
[tex]Distance = |Difference|[/tex]
Substitute [tex]1.7 - (-1/2)[/tex] for Difference;
[tex]Distance = |1.7 - (-1/2)|[/tex]
Hence, the correct option is B
The expression that represents the distance between 1.7 and -0.5 is given by |1.7 - (-0.5)| and this can be determined by using the arithmetic operations.
Given :
Numbers -- 1.7 and -0.5
The distance between two points 1.7 and -0.5 is given by:
Distance = 1.7 + |-0.5|
= 2.2
Now, check all the options in order to determine the correct option:
A) |1.7 - 0.5|
Simplify the above expression.
|1.7 - 0.5| = 1.2
B) |1.7 - (-0.5)|
Simplify the above expression.
|1.7 - (-0.5)| = |1.7 + 0.5| = 2.2
Therefore, the correct option is B).

Hope this is helpful! :)
Answer:
undefined
Step-by-step explanation:
So with the following equation,
-2x + 5 = 13
we plug in 4 for x
-2(4) + 5 = 13
-2 * 4 = -8
-8 + 5 = 13
-8 + 5
-3 = 13
-3 is not 13 so it is undefined
Thus,
the answer is undefined.

What are two different ways you could find the value of a? Explain these methods.
Answer:
Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles are 12. So, we then know that a = 20.
(Root 15^2-9^2=12) (Root 12^2+16^2=20)
Another way is using the whole triangle. The step above used two triangles. The two triangles together makes a big right triangle, so we can again use the Pythagorean theorem. So, the answer again is 20.
(Root 25^2-15^2=20)
Step-by-step explanation:
Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles is 12. So, we then know that a = 20.
We have to find the value of ‘a’ using two different ways.
By the Pythagorean theorem,
By cross multiplication,
16(25) = a2
a2 = 400
Taking square root,
a = 20
Therefore, the length of the other side a = 20.
How do you find the value?
You can calculate the mean value by adding up the numbers and then dividing the result by the number of numbers. For instance, to find the mean value of 4, 1, 3, and 8, first, add up the numbers: 4+1+3+8=16 4 + 1 + 3 + 8 = 16.

Given: XY - tangent to circles k1(P) and k2(O) OX=16, PY=6 and OP=26 Find: XY
Answer:
XY = 24 units
Step-by-step explanation:
First of all, we need to some construction here.
Let us draw a line parallel to XY from point P towards OX, which cuts OX at point Q.
Please refer to the attached figure.
Now, Let us consider triangle OQP which is a right angled triangle, with
Hypotenuse, OP = 26 units
Height, OQ = OX - PY = 16 - 6 = 10 units
Base, PQ = ?
We can use pythagorean theorem here to find the value of PQ.
According to pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = PQ^{2} + OQ^{2}\\\Rightarrow 26^{2} = OQ^{2}+10^{2} \\\Rightarrow PQ^{2} = 26^{2}-10^{2} \\\Rightarrow PQ^{2} = 676-100 \\\Rightarrow PQ^{2} = 576\\\Rightarrow PQ= 24\ units[/tex]
Now, we can see that side PQ is equal to side XY.
[tex]\therefore[/tex] XY = 24 units is the answer.
