Answer:

Answer is 382.5 square inch

Step-by-step explanation:

calculate all the area of the surface

Answer is 382.5 square inch

The surface area of the prism is given by the equation A = 382.5 inches²

The surface area of the prism is calculated as

The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism

Surface Area of the prism = 2B + ph

The area of the triangular prism is A = ph + ( 1/2 ) bh

Given data ,

Let the surface area of the prism be represented as A

Now , the prism consists of 2 right angled triangles and 3 faces of rectangles

So , the base of the triangle b = 9 inches

The height of the triangle h = 10 inches

So , the area of the 2 triangles = 2 ( bh ) / 2

On simplifying the equation , we get

The area of 2 triangles = 9 x 10 = 90 inches²

The area of first rectangle = 9 x 10 = 90 inches²

The area of second rectangle = 9 x 9 = 81 inches²

The area of third rectangle = 13.5 x 9 = 121.5 inches²

So , the area of the prism = area of 2 triangles + area of first rectangle + area of second rectangle + area of third rectangle

Substituting the values in the equation , we get

The area of the prism A = 90 + 90 + 81 + 121.5

The area of the prism A = 382.5 inches²

Hence , the surface area of prism is 382.5 inches²

The total cost of Stun Arun's driving from Indianapolis to Albuquerque, a distance of 1,285 miles, is $244.10.

The total cost means the sum of different expenses.

In this situation, the driving cost per mile for the first 350 miles is different from the rest of the distance.

Therefore, we find the different costs and sum them up to get the total cost incurred by Stun Arun, who is driving from Indianapolis to Albuquerque.

The total distance from Indianapolis to Albuquerque = 1,285 miles

The driving cost per mile for the first 350 miles = $0.27

The total cost for the first 350 miles = $94.50 (350 x $0.27)

The difference between 1,285 and 350 miles = 935 miles

The driving cost per mile for 935 miles = $0.16

The total cost for 935 miles = $149.60 (935 x $0.16)

If ABC is a right angled triangle and angle BAC = 90°. If AD perpendicular to BC and BD=DC then BC² = 4AD² is 4 * AD^2.

How to prove that BC² = 4AD²?​

In right triangle ABC, by Pythagorean theorem, we have:

AC^2 + BC^2 = AB^2

Since AD is perpendicular to BC, by similarity, triangle ABD is similar to triangle ADC. Therefore, we have:

BD/AD = AD/DC

BD = AD^2/DC

Substituting BD into the first equation, we get:

AC^2 + BC^2 = AB^2 = AD^2 + (AD^2/DC)^2

AC^2 + BC^2 = AD^2 + AD^4/DC^2

AC^2 + BC^2 = AD^2(1 + AD^2/DC^2)

Since BD = DC, we have:

AC^2 + BC^2 = AD^2(1 + AD^2/BD^2)

And substituting DC = BD:

AC^2 + BC^2 = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2)

Since AB^2 = AC^2 + BC^2, we have:

BC^2/AD^2 = AB^2/AD^2 - AC^2/AD^2 = (AB^2 + AC^2)/AD^2 - AC^2/AD^2 = (BC^2 + AC^2)/AD^2 = 4

Therefore, BC^2 = 4 * AD^2.

Answer: the smallest number out of the four is 0.13

Step-by-step explanation:

First, let's think about the number 13. It's a whole number and it's pretty big. It's definitely larger than the other numbers we're looking at today.

Next, let's take a look at 0.13. This number is a decimal, which means it's a number that has a whole number part and a fractional part. The whole number part is 0 and the fractional part is 13. So, 0.13 is smaller than 13.

Now, let's move on to 1.03. This is also a decimal and it's a little bit bigger than 0.13, but smaller than 13.

Finally, we have 1.3. This number is a decimal with a whole number part of 1 and a fractional part of 3. It is bigger than 0.13 and 1.03 but smaller than 13.

So, we can see that the smallest number out of the four is 0.13.

First, we need to find the total number of pieces of clothing in the dryer. We do this by adding up the number of black shirts, gray shirts, black sweaters, and gray sweaters: 3 + 8 + 13 + 7 = 31

Next, we need to find the number of gray pieces of clothing in the dryer. We do this by adding up the number of gray shirts and gray sweaters: 8 + 7 = 15

Now we can find the probability of Bill taking out a gray piece of clothing by dividing the number of gray pieces of clothing by the total number of pieces of clothing: 15/31

To find the probability of Bill taking out a shirt, we add the number of black shirts and gray shirts: 3 + 8 = 11

Now we can find the probability of Bill taking out a shirt by dividing the number of shirts by the total number of pieces of clothing: 11/31

To find the probability that the piece of clothing Bill takes out is gray or is a shirt, we add the probability of Bill taking out a gray piece of clothing and the probability of Bill taking out a shirt.

So the probability that the piece of clothing Bill takes out is gray or is a shirt is: (15/31)+(11/31)= 0.58 rounded to the nearest hundredth.

The intersection of events A and B is the event of exactly two tails. This is because event A is defined as exactly two tails and event B is defined as at least two tails.

The intersection of two sets is the set of all elements that are common to both sets. This is also known as the intersection of two conjunctions. To find the intersection of two sets, you take the elements from both sets and keep only the elements that are found in both sets.

There are some components of an equation, that are:

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign.

The "=" sign determines on both sides must always be present when writing an equation.

Given data,

Let the equation be represented as A

Now, the value of A is equal to the original amount of money

The amount Ofelia spends = $ 12

The remaining amount of money Ofelia had=(1/5)A

So, the equation will be

subtract the original amount of money A - amount Ofelia spends = remaining amount of money Ofelia had

By substituting the values in the equation, we get

A - 12 = ( 1/5 )A

Add 12 on both sides of the equation, and we get

A = (1/5)A + 12

Subtract (1/5 )A on both sides of the equation, and we get

A - ( 1/5 )A = 12

On simplifying the equation, we get

(5A - A)/5 = 12

4A/5 = 12

Multiplying by 5 on both sides of the equation, we get

4A = 60

Divide by 4 into both sides of the equation, and we get

Her bi-weekly gross earnings if she works 47 hours during a week of her pay period is $4110.525.

The answer is determined by calculating the income earned for the additional hours she works multiplied by the income earned for the additional hours. This is then added with the gross income for the week and the total is calculated by taking the sum of the two.

Given that her bi-weekly gross earnings are $913.45, and she earns additional compensation for all hours over 40 worked in one week.

For 47 hours, the extra hours worked are 7.

Hence, the compensation for additional hour is:

a = 7 (913.45/2)

a = 3197.075

The gross income would be:

Total = bi-weekly pay + additional hours

T = 913.45 + 3197.075

T = 4110.525

Hence, her bi-weekly gross earnings if she works 47 hours during a week of her pay period is $4110.525.

The top 25 percent, a data point would need to have a z score greater than 0.67.

A z score is a measure of how many standard deviations a data point is from the mean of a data set.

To determine the minimum z score, we first need to find the mean and standard deviation of the data set. The mean represents the center of the data and the standard deviation tells us how spread out the data is.

If a data point has a z score greater than 0, it is above the mean and considered in the top half of the data set.

To be in the top 25 percent, the data point would need to have a z score greater than the value that separates the top 75 percent from the bottom 25 percent.

This value can be found using a table of standard normal distributions or using software that calculates z scores.
