Hello! My name is Galaxy and I will be helping you today! I hope you are having a nice day.
So we can solve this in one single step, I'll start off with solving it.
So first we know that \(AB=DF\) and of which \(DF\) is the Hypotenuse of triangle \(DE F\).
Since the hypotenuse is equal to one of the legs of the 2nd triangle, we cannot use any rule that has Side in it as they are both not really getting us anywhere.
We do know that \(<ABC=<DE F\) as they are both 90 degrees.
As we don't have enough proof, these triangles are not congruent as we would need to do/prove rule RHS.
Cheers!

A cell phone company offers a contract that costs $14.99 plus $0.06 per minute. Find the total number of minutes used if the bill for October was $20.21.
Answers
Answer:
87 minutes
Step-by-step explanation:
Let the total number of minutes = m
Our equation is given as:
$20.21 = $14.99 + 0.06m
20.21 = 14.99 + 0.06m
Collect like terms
0.06m= 20.21 - 14.99

an object's velocity is given by v(t) = 2t2, where time is measured in seconds during a 10-second interval. which expression describes the change in distance during these 10 seconds?
Answers
The expression that describes the change in distance during these 10 seconds is 666.67 meters.
The expression that describes the change in distance during these 10 seconds is given by the integral of the velocity function with respect to time, which is the area under the curve of the velocity function.
So, to find the change in distance during these 10 seconds, we need to integrate the velocity function from 0 to 10 seconds:
∫v(t) dt = ∫2t2 dt = (2/3)t3 + C
Now, we need to evaluate this expression at t = 10 seconds and t = 0 seconds to find the change in distance:
(2/3)(10)3 + C - [(2/3)(0)3 + C] = (2/3)(1000) - (2/3)(0) = 2000/3 = 666.67 meters
(2/3)(10)3 + C - [(2/3)(0)3 + C] = 2000/3 = 666.67 meters
(2/3)(10)3 + C - [(2/3)(0)3 + C] = 666.67 meters
Therefore, the expression that describes the change in distance during these 10 seconds is 666.67 meters.

in a particular region during a 1-year period, there were 1000 deaths. it was observed that 321 people died of a renal failure and 460 people had at least one parent with renal failure. of these 460 people, 115 died of renal failure. calculate the probabil ity of a person that he dies of renal failure if neither of his parents had a renal failure
Answers
The probability of a person dying of renal failure if neither of their parents had renal failure is 0.056 or about 5.6%.
To solve this problem, we can use Bayes' theorem, which states that:
P(A|B) = P(B|A) * P(A) / P(B)
where P(A|B) is the probability of event A given that event B has occurred, P(B|A) is the probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.
In this case, we want to find the probability of a person dying of renal failure given that neither of their parents had renal failure. Let's define the following events:
R: death due to renal failure
P: at least one parent with renal failure
NP: neither parent has renal failure
We are given the following information:
Total deaths = 1000
Deaths due to renal failure (R) = 321
People with at least one parent with renal failure (P) = 460
Deaths due to renal failure among people with at least one parent with renal failure = 115
Using this information, we can calculate the probabilities as follows:
P(R) = 321/1000
P(P) = 460/1000
P(R|P) = 115/460
To find the probability of a person dying of renal failure given that neither of their parents had renal failure (i.e., P(R|NP)), we need to use Bayes' theorem. We can start by finding the probability of neither parent having renal failure (i.e., P(NP)):
P(NP) = 1 - P(P) = 1 - 0.46 = 0.54
Next, we can use the law of total probability to find the probability of dying of renal failure among people with neither parent having renal failure:
P(R|NP) = P(R) * P(NP|R) / P(NP)
We can find P(NP|R) using the formula:
P(NP|R) = P(NP ∩ R) / P(R)
To find P(NP ∩ R), we can use the formula:
P(NP ∩ R) = P(R|NP) * P(NP)
Substituting the values, we get:
P(R|NP) = P(R) * P(NP|R) / P(NP)
= 321/1000 * (1 - 115/460) / 0.54
= 0.056
This calculation shows how conditional probabilities can be calculated using Bayes' theorem and the law of total probability.

You are going on vacation with your family to the beach. You already spent $160
on groceries for the week, and you know that each time you eat out you will spend another $40
.
Answers
Your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal from linear equation concept.
For your vacation at the beach, you have already spent $160 on groceries for the week. In addition, you anticipate spending $40 each time you eat out.
To determine your overall budget for the vacation, you need to consider how many times you plan to eat out during the week. Let's say you plan to eat out 'x' number of times.
Since each time you eat out costs $40, the total amount spent on eating out can be represented by the equation:
Total spent on eating out = $40 * x
Adding this to the amount spent on groceries, the total vacation budget can be calculated as:
Total budget = Amount spent on groceries + Total spent on eating out
Total budget = $160 + ($40 * x)
For example, if you plan to eat out 3 times during the week, the calculation would be:
Total budget = $160 + ($40 * 3)
Total budget = $160 + $120
Total budget = $280
In this case, your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal.
The total budget will vary depending on the number of times you plan to eat out. By adjusting the value of 'x', you can calculate the specific total budget for your vacation.

A middle school took 125 students on a field trip to the zoo. Of the 125 students, 25% had never been to a zoo before. Which of the following is NOT equivalent to 25%?
Answers
The answer is option C) 0.125, as it is NOT equivalent to 25%.
To determine which option is NOT equivalent to 25%, we need to calculate the value of 25% and compare it to the given options.
To find 25% of a value, we multiply that value by 0.25 (since 25% is equivalent to 25/100 = 0.25).
Now let's calculate 25% of 125 students:
25% of 125 = 0.25 × 125 = 31.25.
So, 25% of 125 students is 31.25 students.
Now we can compare this value to the given options and identify which one is NOT equivalent to 25%:
A) 0.25: This option is equivalent to 25% since 0.25 is the decimal representation of 25%.
B) 1/4: This option is also equivalent to 25% because 1/4 is equal to 0.25.
C) 0.125: This option is NOT equivalent to 25% because 0.125 is the decimal representation of 12.5%, not 25%.
D) 0.2: This option is NOT equivalent to 25% because 0.2 is the decimal representation of 20%, not 25%.
Therefore, the answer is option C) 0.125, as it is NOT equivalent to 25%.

One day, eleven babies are born at a hospital. assuming each baby has an equal chance of being a boy or girl, what is the probability that at most nine of the eleven babies are girls?
Answers
The probability of having, at most, 9 girls, is 0.9515
How to get the probability?The probability that a random baby is a girl is:
p = 0.5
And the probability that a random baby is a boy is:
q = 0.5
Then the probability that, at most, 9 out of 11 babys are girls, is given by:
1 - p(10) - p(11)
Where P(10) is the probability that 10 of the babies are girls and p(11) is the probability that the 11 babies are girls.
p(10) = C(11, 10)*(0.5)^10*(0.5)^1 = C(11, 9)*(0.5)^11
Where C(11, 10) is the combinations of 10 elements that we can make with a set of 11 elements, such that:
C(11, 10)= 11!/(11 - 10)!*10! = 11
Replacing that, we get:
P = 11*(0.5)^11 = 0.0054
p(11) = C(11, 11)*0.5^11 = 1*0.5^11 = 0.0005
Then the probability is:
P = 1 - 0.0054 - 0.0005 = 0.9515
