Answers
h= 1/2 gt^2
2= 1/2 * (1.67) t^2
t^2= 1.67
t= 1.29
If the speed is 20 mph and the jump is 2 second, the distance traveled would be:

Mr. jones has two children. the older child is a girl. what is the probability that both children are girls?
Answers
Hope this helps!
Final answer:
Given that the older child is already a girl, the probability that both children of Mr. Jones are girls is 50%, assuming an equal chance of having a boy or a girl.
Explanation:
The question is asking about the probability that both children of Mr. Jones are girls, knowing that the older child is already a girl. Since the older child is a girl, we only need to consider the probability that the second child is a girl. In a typical scenario where the probability of having a boy or a girl is equal (assuming a 50% chance for each), the probability that the second child is a girl, given that the family already has one girl, is simply 0.5 or 50%. Therefore, in this case, the probability that both children are girls is 50%.
Ms Cohen gave a riddle: A string is 2 meters longer than a rod. Half of the rod is 1 meter shorter than half of the string. Is this true or false?
Answers
y: length of the string.
x: length of the rod.
We have the following equation:
y = x + 2
Half of the rod is 1 meter shorter than half of the string
x/2 = y/2-1
Let's rewrite equation 1 to see if it's true:
y = x + 2
(1/2) * y = (1/2) * (x + 2)
(1/2) * y = (1/2) * x + 1
(1/2) * x = (1/2) * y-1

Henry sells rings for $8 each. His expenses are $1.50 per ring, plus $91 for supplies. How many rings does he need to sell for his revenue to equal his expenses?
Answers
Answer:
14 rings.
Step-by-step explanation:
in order to calculate how many rings does he have to sell to break even we first have to calculate the profit that he has on the sell of every ring from which he can take money to pay per supplies, so that would be the selling price minues expenses:
8-1.5=6.5
Now we have to divide the 91 in supplies by the profit:
91/6.5=14
So he has to sell 14 rings in order to break even between expenses and supplies.
Henry needs to sell approximately 14 rings to cover his expenses, which include $1.50 per ring and $91 for supplies, with each ring priced at $8.
To find out how many rings Henry needs to sell for his revenue to equal his expenses, you can set up an equation.
Let's denote the number of rings he needs to sell as "x."
Revenue from selling x rings = Expenses
Revenue is calculated as the price per ring multiplied by the number of rings sold, which is $8x.
Expenses consist of the cost per ring and the supplies cost, which is $1.50x + $91.
So, the equation becomes:
$8x = $1.50x + $91
Now, let's solve for x:
Subtract $1.50x from both sides of the equation:
$8x - $1.50x = $1.50x + $91 - $1.50x
$6.50x = $91
Now, divide both sides by $6.50 to find the value of x:
x = $91 / $6.50
≈ 14
Therefore, Henry needs to sell approximately 14 rings for his revenue to equal his expenses.

Finally, 43 is 5% of what number?
Use the simplified ratio to find the equivalent ratio with a numerator of 43.
Enter your answer in the box.
43 is 5% of __?
Answers
43 ÷ 1/20 = 43 * 20/1 = 860 ← answer
Final answer:
43 is 5% of 860.
Explanation:
To find out what number 43 is 5% of, we can set up a proportion where 5% (or 0.05 when written as a decimal) is equal to 43 over an unknown total number X.
The formula to calculate this is part = percentage imes total, which in this case turns into 43 = 0.05 * X.
To solve for X, divide 43 by 0.05, giving us X = 43 / 0.05 which equals 860.
Therefore, 43 is 5% of 860.
a total of 324 tickets were sold for the school play they were either adult tickets or student tickets the number of student tickets sold was three times the number of adults tickets sold how many adult tickets were sold?
Answers
The correct answer is 81
Final answer:
To find the number of adult tickets sold when a total of 324 tickets were sold for a school play and student tickets were three times the number of adult tickets, we set up the equation x + 3x = 324, solved for x, and found out that 81 adult tickets were sold.
Explanation:
The question is asking us to find out how many adult tickets were sold when a total of 324 tickets were sold for a school play, with the number of student tickets being three times the number of adult tickets sold. To solve this, we let x represent the number of adult tickets. Therefore, 3x will represent the number of student tickets since there are three times as many student tickets as adult tickets.
The equation representing the total number of tickets sold would be: x (adult tickets) + 3x (student tickets) = 324. Simplifying, we have 4x = 324. Dividing both sides by 4 gives us x = 81.
Therefore, the number of adult tickets sold is 81.

Suppose you have two credit cards. The first has a balance of $410 and a credit limit of $1,000. The second has a balance of $510 and a credit limit of $1,000. What is your overall credit utilization? 36% 56% 46% 16% 26%
Answers
In the same way, I will add the balances of each card for a total of $920 and get the percentage of remaining balance:
(sum of balances of two cards) ÷ (sum of credit limits of two cards)
($410 + $510) ÷ ($1000 + $1000) = 0.46 or 46%
Note:
But I have an argument because isn't it that credit utilization is the "percentage used" of the credit limit and for that, I have to subtract 46% from 100% which is 54% and that is not an included in the option
That means you use [tex] \frac{920}{2000} [/tex]. Percent means "out of 100" so we wish to write this fraction with 100 in the denominator (the bottom). We do this by dividing the top (numerator) and bottom (denominator) by the same number. Here we use 20. That gives us [tex]\frac{920}{2000}= \frac{46}{100} =46%[/tex]

The length of time that an auditor spends reviewing an invoice is approximately normally distributed with a mean of 600 seconds and a standard deviation of 100 seconds. what is the probability that an auditor will spend more than 12 minutes on an invoice?
Answers
Explanation:
Since 1 minute = 60 seconds, we multiply 12 minutes by 60 so that 12 minutes = 720 seconds. Thus, we're looking for a probability that the auditor will spend more than 720 seconds.
Now, we get the z-score for 720 seconds by the following formula:
[tex]\text{z-score} = \frac{x - \mu}{\sigma} [/tex]
where
[tex]t = \text{time for the auditor to finish his work } = 720 \text{ seconds} \\ \mu = \text{average time for the auditor to finish his work } = 600 \text{ seconds} \\ \sigma = \text{standard deviation } = 100 \text{ seconds}[/tex]
So, the z-score of 720 seconds is given by:
[tex]\text{z-score} = \frac{x - \mu}{\sigma} \\ \\ \text{z-score} = \frac{720 - 600}{100} \\ \\ \boxed{\text{z-score} = 1.2}[/tex]
Let
t = time for the auditor to finish his work
z = z-score of time t
Since the time is normally distributed, the probability for t > 720 is the same as the probability for z > 1.2. In terms of equation:
[tex]P(t \ \textgreater \ 720) \\ = P(z \ \textgreater \ 1.2) \\ = 1 - P(z \leq 1.2) \\ = 1 - 0.885 \\ \boxed{P(t \ \textgreater \ 720) = 0.115}[/tex]
Hence, there is 11.5% chance that the auditor will spend more than 12 minutes in an invoice.
The probability that an auditor will spend more than 12 minutes on an invoice is approximately 88.49%.
Calculate the probability an auditor will spend more than 12 minutes on an invoice using the Z-score formula for a normal distribution.
The probability that an auditor will spend more than 12 minutes on an invoice can be calculated using the Z-score formula for a normal distribution.
Calculate the Z-score: Z = (12*60 - 600) / 100 = -1.2.Find the probability corresponding to this Z-score using a standard normal distribution table. P(Z > -1.2) = 0.8849.Therefore, the probability that an auditor will spend more than 12 minutes on an invoice is approximately 88.49%.Find the reference angle for 697 degrees
