A firework rocket consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The diameter of the cylindrical base of the rocket is 8 in and the height of the cylinder is 5 in, while the height of the cone is 3 in. Calculate the surface area of the rocket. Leave your answer in terms of π.
Answer:
188π in^2
Step-by-step explanation:
Surface area of the rocket = surface area of the cone + surface area of the cylinder
Surface area of a cone = πr(r+h^2+r^2)
r = 8/2 = 4 in
4π( 4 + 3^2 + 4^2) =
4π ( 4 + 9 + 16) = 116π in^2
Surface area of a cylinder = 2πrh+2πr^2
(2 x n x 4 x 5) + (2 x n x 16)= 72π in^2
116 + 72 = 188π in^2

Fill in the blank. In the triangle below, zº = ?
The measure of z in the triangle is 48.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The sum of the three angles in a triangle is 180.
So,
From the given triangle.
90 + 42 + z = 180
Solving for z.
z = 180 - (90 + 42)
z = 180 - 132
z = 48
Thus,
The measure of z in the triangle is 48.

Answer:
x = 12
Step-by-step explanation:
The angles are supplementary and add up to 180
(8x - 20) + (8x + 8) = 180
Combine like terms
16x - 12 = 180
add 12 to both sides
16x = 192
Divide both sides by16

Number of Hours Slept: 8.5, 7,6.75,5.75, 8.75,6.25,7,7.5, 4.25
Central Tendency is the statistical measure that can be used to represent all the distribution or a dataset using a single value. The most common measures of central tendency are the mode, median, and mean.
How to determine this
Mode is the value that has the highest frequency in a given data set.
So,
8.75 the highest frequency in the data set
Mode = 8.75
Median is the middle of a sorted list of numbers when arranged in ascending order.
So,
4.25, 5.75, 6.25, 6.75, 7, 7, 7.5, 8.5, 8.75 in ascending order
Median = 7
Mean is the average or the most common value in a given set of values.
Mean = 8.5 + 7 + 6.75 + 5.75 + 8.75 + 6.25 + 7 + 7.5 + 4.25/9
Mean = 61.75/9
Mean = 6.8611
Mean = 6.86 to 2 decimal place
Range is the difference between the highest value and lowest values.
Range = Maximum value - Minimum value
Range = 8.75 - 4.25
Range = 4.5

USING SIMILAR TRIANGLES IN INDIRECT MEASUREMENT If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tall is 4 m long, how tall is the tree? Which of the following proportions could not be used to solve the problem? 14/1.8 = x/4 x/1.8 = 14/4 x/14 = 1.8/4
Answer:
14/1.8 = x/4
Step-by-step explanation:
Using similar triangles,
height of man/length of man's shadow = height of tree/length of tree's shadow
1.8/4 = x/14
x/14 = 1.8/4
If we cross-multiply, we have
1.8 × 14 = x × 4
dividing both sides by 4 and 1.8,we have
14/4 = x/1.8
x/1.8 = 14/4
So, the two expressions we have are
x/14 = 1.8/4 and x/1.8 = 14/4.
So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.

Proportional or non proportional?
Answer:
non proportional
Step-by-step explanation:
From the table;
0 = 0
25 = 5^2
100 = 10^2
Since the y values are the output and x is the input, hence;
y = x²
Since the equation is quadratic, hence the table is non proportional

what is the sequence?
243, 81, 27, 9, 3, 1
9514 1404 393
Answer:
an = 243·(1/3)^(n-1) = 3^(6-n)
Step-by-step explanation:
This geometric sequence has a first term of a1=243 and a common ratio of r = 81/243 = 1/3. The general term for it is ...
an = a1·r^(n-1)
an = 243·(1/3)^(n-1)
Making use of the rules of exponents, this can be simplified to ...
an = 3^5·(3^-1)^(n-1) = 3^(5-n+1)
an = 3^(6-n)

0/9
0
The slope of the line is 0.
If u have any questions about what I did feel free to ask in the comments!
Answer:
Slope = 0
Step-by-step explanation:
Formula of finding the slope: (y₂ - y₁) / (x₂ - x₁)
=> So we can say:
(-2, 1) = (x₁, y₁)
(7, 1) = (x₂, y₂)
=> (1 - 1) / (7 - (-2))
=> (0) / (9)
=> 0
Slope of this line = 0
