Answer:
Prove that their corresponsing sides are all congruentsStep-by-step explanation:
Remember that if two figures have corresponding angles congruent, but proportional sides, then those figures are similar.
However, if those figures have corresponding angles and sides congruent, then they are congruent.
Therefore, to determine if two polygons are congruent, that is, in size and shape, we need to prove that their corresponsing sides are all congruents, that way, we'll be able to demonstrate their absolute congruence.
There are 36 students on the bus. There are 2 times as many girls than boys on the bus. On your paper, write a system of liner equations and solve for the number of girls and boys on bus. How many girls are on the bus. A-12 B-24 C-17 D-19
Final answer:
To find the number of girls and boys on the bus, create a system of linear equations and solve for the variables. In this case, there are 12 boys and 24 girls on the bus.
Explanation:
To solve for the number of girls and boys on the bus:
Let G represent the number of girls and B represent the number of boys.
From the problem, G = 2B and G + B = 36.
Substitute G = 2B into the second equation to get 2B + B = 36, which gives B = 12. Therefore, there are 12 boys and 24 girls on the bus.

How many distinguishable 7 letter "words" can be formed using the letters in alabamaalabama?
Final answer:
The number of distinguishable 7-letter words that can be formed using the letters in alabamaalabama is 5040.
Explanation:
The number of distinguishable 7-letter words that can be formed using the letters in alabamaalabama can be calculated using permutations. In this case, we have 12 letters, but some of them are repeated. To calculate the total number of permutations, we need to divide the total number of permutations by the factorial of the number of times each repeated letter appears. The word alabamaalabama has 7 distinct letters, so there are no repeated letters in this case. Therefore, the number of distinguishable 7-letter words that can be formed is simply 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040.

what is the reciprocal of 8-3i
The reciprocal of the complex number 8-3i is found by dividing its complex conjugate (8+3i) by the modulus squared of 8-3i, which is 73. The result is 8/73 + 3i/73.
Explanation:The reciprocal of a complex number is the complex conjugate of that number divided by the modulus squared of the original number. In the case of the complex number 8-3i, its complex conjugate is 8+3i. To find the reciprocal of 8-3i, you would divide this complex conjugate by the modulus squared of 8-3i.
First, calculate the modulus squared of 8-3i:
Modulus of 8-3i = sqrt(82 + (-3)2) = sqrt(64 + 9) = sqrt(73).Modulus squared = (sqrt(73))2 = 73.Then, divide the complex conjugate by this modulus squared to get the reciprocal:
Reciprocal of 8-3i = (8+3i) / 73 = 8/73 + 3i/73.
A city’s annual rainfall totals are normally distributed, and the probability that the city gets more than 43.2 inches of rain in a year is given by P(z≥1.5)=0.0668. If the standard deviation of the city’s yearly rainfall totals is 1.8 inches, what is the city’s mean annual rainfall?
Answer: 40.5 inches
Step-by-step explanation:
Given: A city’s annual rainfall totals are normally distributed.
The probability that the city gets more than 43.2 inches of rain in a year is given by P(z≥1.5)=0.0668
Thus, X=43.2 inches
z=1.5
Standard deviation [tex]\sigma[/tex]=1.8 inches
We know that [tex]z=\frac{X-\mu}{\sigma}[/tex]
[tex]\Rightarrow\mu=X-z\sigma\\\Rightarrow\mu=43.2-1.5\times1.8\\\Rightarrow\mu=43.2-2.7\\\Rightarrow\mu=40.5\ inches[/tex]
Hence, the city’s mean annual rainfall is 40.5 inches.
A model rocket is launched with an initial upward velocity of 67/ms. The rocket's height h (in meters) after t seconds is given by the following.
h= 67t-5t^2
Find all values of t for which the rocket's height is 30 meters.
Round your answer(s) to the nearest hundredth.
(If there is more than one answer, use the "or" button.)
Step-by-step explanation:
The rocket's height h (in meters) after t seconds is given by:
[tex]h=67t-5t^2[/tex]
67 m/s is the initial upward velocity of the rocket. We need to find the values of t for which the rocket's height is 30 meters. So equation (1) becomes :
[tex]67t-5t^2=30[/tex]
[tex]67t-5t^2-30=0[/tex]
The above equation is a quadratic equation. We need to find the value of t.After solving the quadratic equation, we get the values of t are :
t = 0.464 seconds = 0.46 seconds
or
t = 12.936 seconds = 12.94 seconds
Hence, this is the required solution.
The rocket's height is 30 meters at t = 3.79 seconds or t = 0.54 seconds after launch, when solved using the quadratic formula applied to the given equation.
Explanation:To find all values of t for which the rocket's height is 30 meters according to the given quadratic equation h = 67t - 5t2, we need to set the equation equal to 30:
30 = 67t - 5t2
Moving all terms to one side, we obtain:
0 = 5t2 - 67t + 30
Now, we can solve this quadratic equation using the quadratic formula:
t = (-b ± sqrt(b2 - 4ac)) / (2a)
Here, a = 5, b = -67, and c = 30. Plugging these values into the formula we get:
t = (67 ± sqrt(672 - 4 * 5 * 30)) / (10)
Calculating the discriminant and then computing the values for t:
t = 3.79 or t = 0.54
Therefore, the rocket is at 30 meters at approximately t = 3.79 seconds or t = 0.54 seconds after launch, rounded to the nearest hundredth.

How much money will you have at the end of one year if interest is compounded semiannually at 10% on a $600 deposit? A. $661.50 B. $662.00 C. $660.00 D. $659.50
Compound interest on a principal of $600.00 at a rate of 10% per year compounded twice per year over a period of one year results in an accumulated total of $661.50 (principal plus interest).
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
A = P(1 + r/n[tex])^{nt}[/tex]
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
Given:
P = principal (the initial deposit amount) = $600
r = annual interest rate = 10%
n = the number of compounding periods per unit of time = 2
t = 1
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n[tex])^{nt}[/tex]
A = 600.00(1 + 0.1/2[tex])^{(2)(1)}[/tex]
A = 600.00(1 + 0.05[tex])^{(2)}[/tex]
A = $661.50
Therefore, the amount is $661.50.

Joo-Eun can only draw one unique triangle with these side lengths. Joo-Eun can draw exactly two triangles with these side lengths. Joo-Eun can draw more than one triangle with these side lengths.
Answer:
Option 2 is correct .i.e., Joo-Eun can only draw one unique triangle with these side lengths.
Step-by-step explanation:
Measures of sides of triangles are 6 mm , 8 mm and 11 mm
We use a result which states that if sum of two sides of a triangle is greater than 3rd side then triangle with those measures exist.
here,
6 + 8 = 14 > 11
6 + 11 = 17 > 8
8 + 11 = 19 > 6
Therefore, triangle With given measures exist.
Now we use another result which says that a triangle with given measurement can only be drawn as one unique triangle and the angles would be unique for the particular triangle.
Therefore, Option 2 is correct .i.e., Joo-Eun can only draw one unique triangle with these side lengths.
The statement that is true about Joo-Eun’s plan is: Joo-Eun can only draw one unique triangle with these side lengths.

A television station would like to measure the ability of its weather forecaster. Past data have been collected that indicate the following:
Probability of sunshine on sunny days is 0.8
Probability of sunshine on rainy days is 0.4
Probability of a sunny day is 0.6
Find the probability of
(I)sunshine
(II)sunny given that the forecaster has predicted sunshine
Final answer:
The probability of sunshine on any given day is 0.64, and the probability that it is sunny given that sunshine has been forecasted is 0.75.
Explanation:
To address the question, we'll first define the given probabilities:
Probability of sunshine on sunny days (P(S|Sunny)) = 0.8Probability of sunshine on rainy days (P(S|Rainy)) = 0.4Probability of a sunny day (P(Sunny)) = 0.6Probability of a rainy day is the complement of a sunny day (P(Rainy)) = 0.4, since P(Sunny) + P(Rainy) = 1
Part I: Finding the probability of sunshine
To find the overall probability of sunshine, we use the law of total probability:
P(S) = P(S|Sunny) × P(Sunny) + P(S|Rainy) × P(Rainy)P(S) = 0.8 × 0.6 + 0.4 × 0.4 = 0.48 + 0.16 = 0.64Part II: Finding the probability of sunny given sunshine
To find the probability of sunny given that the forecaster has predicted sunshine, we use Bayes' theorem:
P(Sunny|S) = [P(S|Sunny) × P(Sunny)] / P(S) = (0.8 × 0.6) / 0.64 = 0.48 / 0.64 = 0.75930 miles to travel with a car that gets 22 miles per gallon. How much will it cost to travel if gas costs 2.03 a gallon?
