The area of a circle is 225 pie square inches. Find the area of the sector whose central angle is 45°.

Answers

Consider this option:
The central angle for whole circle is 360°, it means that angle 45° has 45/360=1/8 part of the circle.
If the area of the circle is 225π, then the area of the sector 45° is 225π/8≈28.125π (in.²)

answer: 28.125π in².

The area of the sector of the circle is 28.125π inches²

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the centre for every angle

The total internal angle is 360° about the centre

The area of the sector of the circle = ( θ / 360° )πr²

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

Given data ,

Let the area of the circle be = A

The value of A = 225 inches²

Now , the area of the sector whose central angle is 45° is calculated by

The area of the sector of the circle = ( θ / 360° )πr²

Substituting the value for θ = 45° , we get

Area of the sector of the circle = ( 45/360 ) x 225

= ( 1/8 ) x 225

= 28.125 inches²

Therefore , the area of the sector is 28.125 inches²

Hence , The area of the sector of the circle is 28.125π inches²

Distributive property was the first property used in STEP 1, where -4 was distributed to -3x+ 2 resulting in the equation in STEP 1. Next in STEP 2, commutative property of addition no matter how 12x and 6x are arranged, when you add them together the result will be the same.
*Take note that 12x and 6x are put together because they are like terms.

For Steps 3 and 4, you will see that the addition property of equality was used in STEP 3. To keep the equation equal, you will add the same number on both sides.

STEP 4 uses Division property of Equality. Like Step 3, to keep both sides of the equation equal, you must divide both sides with the same number. It keeps the statement true by doing so.

STEP 4 and 5 uses transitive property if you examine both as a whole.
Transitive property assumes that if a = b and b = c, then a = c

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.

On the surface of the moon, the value of g is 1.67 m/s2. What is the horizontal distance traveled during a 2.00-meter high jump if the jumper runs as at 20 miles per hour?

Answers

To solve this question, you need to find how long jump is. For 2m high with 1.67 m/s2 it would be:

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:
20 miles/ hour * 1.29 second * (1 hour/3600second)= 0.007179 miles

If you need to convert it to meter then: 0.007179 mile * 1609.34meter/ mile= 11.55 meter

Mr. jones has two children. the older child is a girl. what is the probability that both children are girls?

Answers

Since we already know that the older child is a girl (a 100% chance to be a girl), there must be a 50% chance that the other child is a girl. Therefore, the probability that both children are girls is 50%.
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%.

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

5% = 5/100 = 1/20

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.

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.

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

Answer: 11.5%

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%.

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

The question asked for overall credit utilization, so instead of considering individual credit cards for computation, I will use the credit limits of two cards as if it is just one credit card. That will give me a total limit of $2000.

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

Your have a balance of $410 on one card and $510 on the other. Together (add) this is a balance of $920. Your total credit limit is $2000 (add the limits of each card).

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]
