Type the correct answer in the box.
Net of a triangular prism includes 3 same-sized rectangles that coincide along their width. Each rectangle has length labeled 10 centimeters and width labeled 15 centimeters. Isosceles triangle is placed above and below of second rectangle.
The surface area of the three-dimensional figure is
square centimeters.
The surface area of this three-dimensional figure is equal to 536.6 square centimeters.
How to determine the surface area?First of all, we would determine the total area of the three rectangles by using this formula:
Total area = 3 × Length × Width
Total area = 3 × 15 × 10
Total area = 450 cm².
Next, we would determine the total area of the two triangles by using this formula:
Total area = 2 × (1/2 × b × h)
Total area = b × h
Total area = 8.66 × 10
Total area = 86.6 cm².
Surface area = 450 + 86.6
Surface area = 536.6 cm².

Calculate the t-score for a sampling distribution mean of 10.5, a standard deviation of 1.5, and a size of 36 drawn from a population that has a mean of 10.
The t- score for a sampling distribution is 2
The t-score is the number of standard deviations from the mean in the t-distribution.
The upper and lower bounds of a confidence interval when the data are approximately normally distributed.
T-scores and confidence intervals
Confidence intervals use t-scores to calculate the upper and lower bounds of the prediction interval. The t-score used to generate the upper and lower bounds is also known as the critical t or t* value.
The t- distribution is given by
t=(x – μ) / (S / √n)
t = T – Distribution
x = sample mean
μ = population mean
S = standard deviation
n = Sample size
It is given that sampling distribution mean of 10.5, a standard deviation of 1.5, and a size of 36 drawn from a population that has a mean of 10.
We need to find the t-score for sampling distribution
t=(x – μ) / (S / √n)
Here, x= 10.5 , μ= 10, S=1.5, n=36
t = (10.5 - 10)/ (1.5 /√36)

enter your response here%. (Round to two decimal places.)
The after-tax rate of return is 1.84%, the real return is 0.721%, the total monetary return is $1530 and the implications become very challenging to grow with such a return as the taxes
Given that money market account investment at 2.55 percent (APY), a 1.11 % inflation rate, a 28 percent marginal tax bracket, and a constant $60000 balance.
Cash management is the backbone of any business. Cash management ensures that the company operates according to established standards and optimizes the use of funds to avoid wasting resources. Liquidity management decisions are therefore key to preserving a company's capital and profitability.
Firstly, we will find the after-tax return rate, we get
After-tax return rate= Before tax rate of return \times ( 1 - tax rate)
After-tax rate of return = 0.0255× ( 1 - 0.28)
After-tax rate of return = 0.0255×0.72
After-tax rate of return=1.84%
Now, we will find the real return, we get
Real return=((1+After-tax Return)/(1+inflation rate))-1
Real return=((1+0.0184)/(1+0.0111))-1
Real return=(1.0184/1.0111)-1
Real return=1.00721-1
Real return=0.721%
Furthermore, we will find the total monetary return, we get
Total monetary rate=Balance×Before tax rate of return
Total monetary rate=60000×2.55%
Total monetary rate=$1530.
The implications of this result for cash management decisions is that it becomes very challenging to grow with such a return as the taxes and inflation is draining the returns and leaving only with negative returns.
Hence, the after-tax rate of return is 1.84%, the real return is 0.721%, the total monetary return is $1530 and the implications become very challenging to grow with such a return as the taxes and inflation is draining the returns and leaving only with negative returns.

Approximately how many years will it take for the world’s population to increase to 8,252,000,000 people? Since there will be the original 100% plus an additional 2% each year, the base in the exponential equation is 1.02. Use the equation 8252=(6080)(1.02)x, where x is the number of years. Round to the nearest year.
The number of years it will take for the world’s population to increase to 8,252,000,000 people is 16
How to determine the number of years?This implies that we calculate the value of x
The equation is given as:
8252=(6080)(1.02)^x
Divide both sides by 6080
1.36 = (1.02)^x
Take the logarithm of both sides
log(1.36) = x * log(1.02)
Divide both sides log(1.02)
x = log(1.36)/log(1.02)
Evaluate the quotient
x = 16
Hence, the number of years is 16

General admission tickets to a play cost $18 each. Reserved seats cost $22 each. There were 20 reserved seats sold. There were 28 more general admission tickets sold than reserved seats. How much money was paid for all of the tickets put together? Complete the chart and answer the question:
Answer:
$22 * (20) + $18 * (48) = $1304
Step-by-step explanation:
There are 20 reserved seats so it would be: $22 * 20 = $440 for all reserved seats
There are 28 general admission tickets more than reserved seats ticket so number of general admission tickets is: 20 + 28 = 48 (tickets)
Each general admission tickets cost $18, so: $18 * 48 = $864 for all general admission tickets
So the total money was paid for all of the tickets is: $440 + $864 = $1304

Answer:
Multiple both sides by -2 or Distribute negative one-half over (x+4)

-1/2(x+4) = 6
If I multiple both sides by -2, I am clearing the fraction:
(-2)(-1/2)(x+4) = 6(-2)
x+4 = -12
x = -16

a display at an aquarium has sea stars to wolf eels in a ratio 4 : 5. It also has 5/8 as many rockfish as sea stars. there are 40 more wolf eels than rock fish. How many sea stars are there?
The number of sea stars is 64.
What is a ratio?
Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other.
In general, a: b, which can be interpreted as "a is to b," is used to denote a ratio between two quantities, let's say "a" and "b."
This ratio is expressed in fraction form as a/b. We utilize the same method for further simplifying a ratio as we use for further simplifying a fraction.
According to the question,
Ratio of sea stars to wolf eels = 4:5
Number of rock fish= 5/8 (Number of sea stars)
Number of wolf eels - Number of rock fish = 40
Using the given information, we get,
Number of sea stars = 8/5 (Number of rock fish)
On simplification,
Number of wolf eels = 80
So, number of sea stars = (4/5)*80

The coordinates of the edges of the mini-solar cooker are (x₁, y₁) = (0, - 60) and (x₂, y₂) = (0, 60).
The distance between the two edges is 120 centimeters.
The equation for the parabolic mirror is x + 32 = (2/225) · y².
How to analyze a parabolical mini-solar cooker
Herein we must understand the geometry of the design of the mini-solar cooker to determine all needed information. The y-coordinates of the edges of the cooker are determined by Pythagorean theorem:
[tex]y = \pm \sqrt{(68\,cm)^{2}-(32\,cm)^{2}}[/tex]
y = ± 60
The coordinates of the edges of the mini-solar cooker are (x₁, y₁) = (0, - 60) and (x₂, y₂) = (0, 60). The distance between the two edges is 120 centimeters.
Lastly, the equation of the parabolic mirror can be determined based on the equation of the parabola in vertex form:
x - h = C · (y - k)² (1)
Where:
h, k - Coordinates of the vertex
C - Vertex constant
If we know that (h, k) = (- 32, 0) and (x, y) = (0, 60), then the vertex constant of the equation of the parabola is:
0 + 32 = C · 60²
C = 2/225
Then, the equation for the parabolic mirror is x + 32 = (2/225) · y².
