Answer:
2064 cm²
Step-by-step explanation:
You want the surface area of a prism that is 30 cm between bases that are trapezoids with parallel sides 27 cm and 6 cm that are 8 cm apart, and slant sides that are 10 cm and 17 cm.
Base areaThe area of each trapezoidal base is ...
A = 1/2(b1 +b2)h
There are two identical bases, so their total area is ...
2A = (b1 +b2)h = (27 cm +6 cm)(8 cm) = 264 cm²
Lateral area
The lateral area of the prism is the area of the four rectangular faces. Each is 30 cm wide, and their total length is the perimeter of the base;
P = 27 cm +10 cm +6 cm +17 cm = 60 cm
lateral area = Ph = (60 cm)(30 cm) = 1800 cm²
Total surface area
The total surface area of the prism is the sum of the base area and the lateral area:
total area = base area + lateral area
total area = 264 cm² +1800 cm² = 2064 cm²
The surface area of the solid prism is 2064 cm².
the top of an electric pole is s supported by a wire of 26 ft long on the ground level. how far is tightened spot from the foot of the pole if its height is 24 ft?
Answer:
The tightened spot is 10 feet away from the foot of the pole.
Step-by-step explanation:
1. Draw the diagram. Notice that the shape of the electric pole and its supporting wire creates a right triangle.
2. We know 2 side lengths already (26ft, 24ft), and we need to find 1 more side length. Therefore, to find the 3rd side length of a right-triangle, utilize Pythagoras' Theorem.
⭐What is the Pythagoras' Theorem?
[tex](C)^2 = (A)^2 + (B)^2[/tex]An equation to find a 3rd side lengthC = hypotenuseA = one legB = another leg3. Substitute the values of the side lengths into the equation, and solve for the unknown side length.
Let B= the distance from the tightened spot to the foot of the pole.
[tex](C)^2 = (A)^2 + (B)^2[/tex]
[tex]26^2 = 24^2 + B^2[/tex]
[tex]676 = 576 + B^2[/tex]
[tex]100 = B^2[/tex]
[tex]\sqrt{100} = \sqrt{(B)^2}[/tex]
[tex]10 = B[/tex]
∴ The tightened spot is 10 feet away from the foot of the pole.

10. The figures below are similar.
State the ratio of similarity and then use it
to find the value of x. (2 points)
Answer:
x = 16.5
Step-by-step explanation:
the ratio of similarity is the ratio of corresponding sides, that is
ratio = [tex]\frac{18}{12}[/tex] = [tex]\frac{15}{10}[/tex] = 1.5
Then
[tex]\frac{x}{11}[/tex] = 1.5 ( multiply both sides by 11 to clear the fraction )
x = 16.5

Answer:
y(x) = integral(6 c^2 - 20 x^3)/(5 x^2 + 3) dx = -2 x^2 + 1/5 log(5 i x + sqrt(15)) (-i sqrt(15) c^2 + 6) + 1/5 log(-5 i x + sqrt(15)) (i sqrt(15) c^2 + 6) + k_1, where k_1 is an arbitrary constant.
Step-by-step explanation:
Rewrite the equation to -((6 c^2 - 20 x^3) dx)/(3 + 5 x^2) + dy = 0 and solve
Solve (dy(x))/(dx) = (6 c^2 - 20 x^3)/(5 x^2 + 3):
Integrate both sides with respect to x:
Answer: y(x) = integral(6 c^2 - 20 x^3)/(5 x^2 + 3) dx = -2 x^2 + 1/5 log(5 i x + sqrt(15)) (-i sqrt(15) c^2 + 6) + 1/5 log(-5 i x + sqrt(15)) (i sqrt(15) c^2 + 6) + k_1, where k_1 is an arbitrary constant.

the high temperature for the week were 50, 52, 71, 54, and 51. what is the mean of the temperatures without the outlier?
Answer: 55.6 or 55.60
Step-by-step explanation: Okay, so we have to add up all the numbers and divide by how many numbers there are, so we would add 50 + 52 + 71 (Including this outlier) + 54 + 51, to get 278. Now, since there are 5 numbers in the data set, we would divide 278 by 6, and you should get 55.6 or 55.60 (They are the same thing)

If 5/33 is expressed in decimal form, what digit is in the 92nd place to the right of the decimal point?
Answer: 5
Step-by-step explanation:
If you plug 5/33 into a calculator (or just solve with long division), you'll find that it makes 0.151515... (with 15 repeating forever.)
In every EVEN decimal place there's a 5, but in every ODD decimal place there's a 1. (The first decimal place is 1, the second is 5, etc.)
Since 92 is an even number, there is a 5 in the 92nd decimal place.

Describe relative frequency.A relative frequency describes how frequently a particular kind of event happens among all observations. It is a kind of frequency that employs fractions, percentages, and proportions. The ratio of the total number of events occurring in a scenario to the number of times an event occurs is known as relative frequency. Relative Frequency = Subgroup Frequency/Total Frequency is the formula for relative frequency. A relative frequency count is a way to count how many times an event happens compared to all the other events. It can be described as a percentage.

Write the tangent equation to solve for angle f
Answer:
tan θ = 24/7
Angle F = tan⁻¹(24/7) = 73.7° (1 d.p.)
Step-by-step explanation:
tan θ = Opposite/Adjacent
Opposite side is the side opposite angle θ
Adjacent side is the side next to the right angle and the angle θ
θ = Angle F
tan θ = 24/7
Angle F = tan⁻¹(24/7) = 73.7 (1 d.p.)
Let X and Y be independent and identically distributed exponential random variables with rate λ.
Let U = X/Y and let V = XY . Find the joint desnity for (U, V ). Also find the marginal densities fU (u)
and fV (v).
The joint density for (U, V) is given by:
f(u,v) = fX/Y,XY(u,v) = fX(v/u) * fY(v/u) * |(v/u)|= λ^2 * v * e^(-λv/u) * |(v/u)|
The marginal density for U is given by:
fU(u) = ∫f(u,v)dv
= ∫λ^2 * v * e^(-λv/u) * |(v/u)|dv
= λ^2 * u * ∫ve^(-λv/u)dv
= λ^2 * u * (-(u/λ)^2 * e^(-λv/u))|v=0 to v=∞
= λ^2 * u * (-(u/λ)^2)
= λ^3 * u^2
The marginal density for V is given by:
fV(v) = ∫f(u,v)du
= ∫λ^2 * v * e^(-λv/u) * |(v/u)|du
= λ * v * ∫e^(-λv/u) * |(v/u)|du
= λ * v * (∫e^(-λv/u)du)|v=0 to v=∞
= λ * v * (-(u/λ) * e^(-λv/u))|u=0 to u=∞
= λ * v * (-1)
= λ * v
Therefore, the joint density for (U, V) is
f(u,v) = λ^2 * v * e^(-λv/u) * |(v/u)|du.Learn more about Marginal Density here:

proportional to the number of minutes, t, since the medication was taken. Which
would be the general formula for this relationship?
a) A = k/t
b) A = kt
c) A = 1/t
d) A = -t
The general formula for the relationship amount of medication, A, that remains in your bloodstream is inversely proportional to the number of minutes is a) A = k/t.
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
We know we can write y is inversely proportional to x as,
y ∝ 1/x.
y = k/x, where k is the constant of proportionality.
Therefore, The amount of medication, A, that remains in your bloodstream is inversely proportional to the number of minutes, t can be written as,
A = k/t.

A school bought 105 boxes of chocolate cookies and 22 boxes of vanilla cookies
for a fundraiser. Each box contained 12 cookies.
The school then repacked the cookies into smaller packs of 8 to sell.
How many small packs were there? How many cookies were left over?
Answer:190 small packs and 4 cookies left over
Step-by-step explanation:
Add the boxes of cookies together 105+22=127
Multiply each box by 12
127 x 12=1524
Because we need to put them into smaller packs of 8 cookies
we need to divide by 8
1524÷8=190 small boxes
This is a total of 190 x 8=1520 cookies there are 4 cookies left over

Define angle.In planar geometry, an angle is a shape made up of two rays or lines that share an endpoint. The Latin word "angulus," which means "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle. A geometrical shape called an angle is created by connecting two rays at their termini. In most cases, an angle is expressed in degrees. In geometry, there are several different kinds of angles.
