Answer:

$ 42.78

Step-by-step explanation:

See attachment for the figure

The formula of the lateral area of the rectangular prism is:

LA = perimeter of base × height

Given:

The length of the base 'l' = 9 m

The width of the base 'w'= 5 m

The height of the prism 'h'= 7 m

perimeter of the base can be determined by

Perimeter of base = 2(l  + w ) =>2(9 + 5)

Perimeter of base = 28 m

By using the formula of the lateral area

LA = 28 × 7

LA = 196 m²

Required:

sheet steel cost per square meter=?

Given: The total cost of the sheet steel was $8384

            LA =  196 m²

By Dividing the cost by the lateral area, we'll know our unit cost

therefore, The unit cost = 8384 ÷ 196

The unit cost =$ 42.78

The sheet steel costed $42.78 per square meter

Answer:

1,000

Step-by-step explanation:

$12,000÷800 =15. x=people attending

$15,000÷x=15. x=1,000

$15,000×1,000=15

Final answer:

Using the concept of direct variation, a constant of variation ($15 per person) was calculated using the provided sales and attendance. This constant was then used to find the attendance for a different sales amount, which was found to be 1000 people for $15,000 in sales.

Explanation:

The question asks us to determine how many people attended a baseball game based on the direct variation between sales and attendance. Since we know that at 800 people the sales are $12,000, we can set up a proportion to solve for the number of people when sales are $15,000.

First, we find the constant of variation (k) by dividing the sales by the number of people for the given data point:

k = Sales / Number of people = $12,000 / 800 = $15 per person

Next, we use this constant to find the number of people when sales are $15,000:

Number of people = Sales / k = $15,000 / $15 per person = 1000 people

Therefore, 1000 people attended the game when the sales were $15,000.

Step-by-step explanation:

Given:

156 $ to United way  for  a year.

With each weeks.

To Find:

How much amount he will take for pay for giving to United way.

Solution:

He wants to give money to united way in a year

So there are 365 days per year

And he held money from is his pay every week

So there 7 days per weeks.

Hence Total number of weeks in a year will given by,

=365/7

=52 weeks per year

Now he held every week from his pay to United way

And Total amount to distribute is about 156 $ in 52 weeks.

So Every week amount will be

22.7

Step-by-step explanation:

The required mean absolute deviation is 22.9, rounded to the nearest tenth.

Statistic is the study of mathematics that deals with relations between comprehensive data.

The mean weight of the animals is 44.3.

To find the mean absolute deviation, we take the absolute value of the difference between each weight and the mean, and then take the average:

= (|5-44.3| + |24-44.3| + |38-44.3| + |52-44.3| + |66-44.3| + |85-44.3|) / 6
= (39.3 + 20.3 + 6.3 + 8.3 + 22.3 + 41.3) / 6
= 137.5 / 6 = 22.9

So the mean absolute deviation is 22.9, rounded to the nearest tenth.

Answer:

The volume of the punch bowl is 1385 cubic inches.

Step-by-step explanation:

Cylinder:

Given that,

A punch bowl is in the shape of a cylinder.

The diameter of the punch bowl is 14 inches.

Then the radius of the punch bowl is [tex]=\frac{14}{2}[/tex] = 7 inches.

The height of the punch bowl is = 10 inches.

The punch bowl is need to fill 1 inch from the top.

So, we need to fill the punch bowl = (10-1) =9 inches.

The volume of the punch bowl is = [tex]\pi r^2 h[/tex]

                                                       [tex]=(3.14 \times 7^2\times 9)[/tex] cubic inches

                                                      ≈1385 cubic inches.

Final answer:

To fill a cylindrical punch bowl to 1 inch below the top, you would need to calculate the volume using the formula V = πr²h with the radius being half the diameter, and the height being the bowl's height minus 1 inch. Using the given dimensions, the volume needed is 1383 cubic inches of punch.

Explanation:

Calculating the Volume of a Cylinder Punch Bowl

To calculate the volume of the punch needed to fill a cylindrical punch bowl, we need to use the volume formula for a cylinder, which is V = πr²h. The diameter of the punch bowl is given as 14 inches, so the radius (r) is half of that, which is 7 inches. The height (h) of the punch needed is the height of the bowl minus 1 inch, which is 10 inches - 1 inch = 9 inches. Now, we can plug these values into the formula and use 3.14 for π:

V = π × r² × h = 3.14 × (7 inches)² × 9 inches

Doing the calculation:

V = 3.14 × 49 sq inches × 9 inches = 3.14 × 441 cubic inches = 1383.14 cubic inches. When we round this to the nearest whole number, we get a volume of 1383 cubic inches of punch needed to fill the bowl to the desired level.

The correct formula for k(x) = g(x) × h(x), given that g(x) is an odd function and h(x) is an even function, is k(x) = x 2ⁿ - 1.

Explanation:

The student is asking which formula represents k(x) = g(x) × h(x). Given the functions g(x) = x³ - 3x and h(x) = e⁽¹x², and knowing that the product of an odd function and an even function is an odd function, the correct representation of k(x) will also be an odd function.

From the provided options, the correct formula must satisfy the conditions of being an odd function, meaning that k(-x) = -k(x). This property holds only for option two, k(x) = x 2ⁿ - 1, because this is the only option where k(x) changes sign when x is replaced with -x, fulfilling the criteria of an odd function.

Answer:

$1,444.50.

Step-by-step explanation:

To calculate the combined cost of the repair and sales tax at Store B:

Cost of repair at Store B: $1,350

Sales tax rate at Store B: 7%

Now, let's calculate the sales tax:

Sales tax = 1,350 × 7/100 = 1,350 × 0.07 = 94.50

Next, add the sales tax to the repair cost:

Total cost = 1,350 + 94.50 = 1,444.50

Thus, the combined cost of the repair and sales tax at Store B is $1,444.50.

Answer:

A is 4x^2+84x+440 and B=840 square inches

Step-by-step explanation:

A is 4x^2+84x+440 and B=840 square inches

The task for a is to write a polynomial in standard form that represents the combined area of the photo and the frame. First, lets start with the bottom of the picture and frame.  On the bottom, you have 2x+ 22 inches.  Then the side of the picture and frame is 2x+20 inches. Writing in polynomial form, it would be  (2x+22)(2x+20). You would get 4x^2+84x+440 since you are using the FOIL method. Now for part b, we know that the width of the frame(or x) is 4 inches. Now we plug that into the equation.  84x is 84x4. 84x4=336   x^2 is 16.   There are four of those as you can see in the equation so 16x4=64    

336+64=400 inches    Frame= 400 inches

400 inches plus the picture(440 inches) =  840 square inches.

Length of the rectangular photo = 22 inches

Width of the rectangular photo = 20 inches

Since, width of the frame outside the photo = x inches

Therefore, increase in length and width of the photo with frame = (x + x)

                                                                                                           = 2x inches

Length of the photo with frame = (22 + 2x) inches

Width of the photo with frame = (20 + 2x) inches

Combined Area of the photo in the frame = Length × Width

                                                                      = (22 + 2x)(20 + 2x)

                                                                      = 22(20 + 2x) + 2x(20 + 2x)

                                                                      = 440 + 44x + 40x + 4x²

                                                                      = 4x² + 84x + 440

Therefore, polynomial representing the combined area of the photo in the frame will be (4x² + 84x + 440) square inches.

If width of the frame = 4 inches

Combined area of the photo = 4(4)² + 84(4) + 440

                                                 = 840 square inches

Final answer:

There is no integer power of 7 that exactly equals 2041, as 7 to the power of 4 is 2401, which is the closest integer power of 7 that is higher than 2041.

Explanation:

The question asks to determine the power of 7 that equals 2041, which is written mathematically as 2041 = 7x. To solve this, one approach is to estimate and refine by trying different powers of 7 until we get close to 2041. Here's how the estimation process could work:

Start with lower powers of 7 like 72 = 49, and increase the exponent.

Notice that 73 = 343 and 74 = 2401.

Since 2401 is just above 2041, we suspect our answer will be close to 4 but slightly less.

Checking with a calculator or using a division strategy, we can confirm that 2041 is slightly below 74, making it clear there's no integer power of 7 that equals 2041.

Therefore, there isn't an integer power of 7 that precisely equals 2041.

The number of students in the classroom is 24, as it is the smallest multiple of 2, 3, 4, 6, and 8 that is between more than 20 and fewer than 30.

The student is given a number puzzle in a mathematics classroom setting. Based on the teacher's hints, the number of students in the classroom should be a common multiple of 2, 3, 4, 6, and 8 that also fits within the given range of between more than 20 and fewer than 30. We need to find the least common multiple (LCM) of these numbers that fits the criteria.

First, realize that since the number must be divisible by 8, it must be at least 24 since 16 is too low.

Next, confirm if 24 is also divisible by 2, 3, 4, and 6. It is indeed, as 24=2x12, 24=3x8, 24=4x6, and 24=6x4.

Because 24 is the only number between 20 and 30 that is divisible by all the given numbers, it is the answer.

Thus, the number of students in the classroom is 24.
