Answer:

40 cm

Step-by-step explanation:

a square has 4 equal length sides, to get area you multiply two of those sides, 10 x 10 = 100, so each side is 10cm long, adding all of the sides together gets you 40cm.

Answer:

40cm

Step-by-step explanation:

We know that the formula for area of a square is side length squared or [tex]s^2[/tex]

In this case, [tex]s^2=100[/tex]. So we can go through the following steps in order to solve for s

[tex]s^2=100\\\sqrt{s^2} =\sqrt{100} \\\\s=10[/tex]

If one side equals 10, and we know all squares have 4 equal sides, then we can multiple 10 * 4 or add 10+ 10 + 10 + 10.

Our outcome is 40!

Answer:

Option A. 2

Step-by-step explanation:

From the question given, we were told that the total outcome in event A is 5.

Now if region 2 is 6, 7 or 8, as given in the other options, it therefore means that the total out in event A will be more than 5. So region 2 must be 2 in order to satisfy the event A.

Further more, considering the diagram, event B is bigger than event A. With this idea we can give the summary in diagram as follow:

Region 1 => 3 outcomes

Region 2 => 2 outcomes

Region 3 => 4 outcomes

Region 4 => 6 outcomes

Total => 15 outcomes

Now we can see that the total outcome correspond to the total outcome of 15 given in the question.

Therefore, region 2 has 2 outcome

Given the information, we can determine that B has 4 outcomes, but the number of outcomes specifically in region 2 cannot be found without additional information.

Let's break down the given information one piece at a time. The sample space (S) consists of 15 equally likely outcomes. Out of these, we know that 5 outcomes are in region A, and 6 outcomes neither belong to event A nor to event B.

Since events A and B are independent, they do not share outcomes. Now, we can calculate the number of outcomes in event B by subtracting the outcomes not belonging in A or B and belonging in A from the total outcomes. Hence, there are 15 - 5 - 6 = 4 outcomes in event B.

However, the question requires us to find outcomes in the second region (2). Since the regions were not specified concerning events A and B, we cannot identify the precise number of outcomes in region 2. Therefore, we cannot accurately answer the question with the given information.

Answer:

The volume of the prism is 476 cm^3

Step-by-step explanation:

Mathematically, the volume of a right prism can be calculated using the formula area of the base * height of the prism

Here, the base is a parallelogram and thus, the area of the base can be calculated using the formula A = bh where b is the parallelogram base and h is the height

in the question the parallelogram has a base of 8.5cm with the height at that point as 4cm

The area of that parallelogram is thus 4 * 8.5 = 34 cm^2

the volume of the right pyramid is thus 34 * 14 = 476 cm^3

Answer:

-19/248

Step-by-step explanation:

We have been given that a cylinder was enlarged by a scale factor of 4. The new volume is 2,240 cubic units. We are asked to find the volume of original cylinder.

We know that a cylinder is a three dimensional object. Since scale factor is 4, so each side of new cylinder will be 4 times the side of original side of cylinder.

Due to 3 dimensions, the volume of new cylinder is [tex]4^3[/tex] times the volume of original cylinder.

[tex]\text{Volume of original cylinder}\times 4^3=\text{Volume of new cylinder}[/tex]

[tex]\text{Volume of original cylinder}\times 64=2240[/tex]

[tex]\frac{\text{Volume of original cylinder}\times 64}{64}=\frac{2240}{64}[/tex]

[tex]\text{Volume of original cylinder}=35[/tex]

Therefore, the volume of the original cylinder is 35 cubic units.

Answer:

Step-by-step explanation:

Answer:

358,000,000 BTU's.

Step-by-step explanation:

Given that the radius is equal to 5 ft. and we need to find the volume of sphere~we can use the following formula. Additionally, we will use 3.14159 to be more accurate in this case...

[tex]V =\frac{4}{3} \pi r^3\\V=\frac{4}{3} (3.14159)5^3\\V=4.18878667(125)\\V=523.6[/tex]

So the volume is 523.6 cubic ft!

To convert this to gallons...

[tex]\\1 ft^3 = 7.48052 gal\\523.6 ft^3 = 3916.8 gallons[/tex]

The final step is to multiply this amount by the original 91,500 BTU, when we do this we get...

[tex]3916.8*91500=358387200[/tex]

The nearest million from this number is 358,000,000!

Final answer:

To determine the number of BTUs a spherical storage tank provides, find the tank's volume in gallons by converting from cubic feet, then multiply by 91,500 BTU per gallon and round to the nearest million BTUs.

Explanation:

To calculate the number of BTUs a spherical storage tank can provide, given in gallons, we first need to know the tank volume in cubic feet. Let's assume the student provides this volume. Since 1 cubic foot is equivalent to approximately 7.48 gallons of liquid, we divide the volume in cubic feet by 7.48 to find the number of gallons of propane the tank can hold. Each gallon of propane yields approximately 91,500 BTU.

To find the total BTUs, we use the following steps:

Calculate the number of gallons in the tank by multiplying the volume in cubic feet by 7.48.

Multiply the number of gallons by 91,500 BTU per gallon to get the total BTUs in the tank.

Round the result to the nearest million BTUs, as the question asks.

For example, if a spherical storage tank has a volume of 100 cubic feet, the number of gallons it can hold would be 100 cubic feet * 7.48 gallons/cubic foot = 748 gallons. Then, the total BTUs would be 748 gallons * 91,500 BTU/gallon = approximately 68,442,000 BTU, which would then be rounded to 68 million BTUs.

Answer:

49.13 in

Step-by-step explanation:

circle circumference: 25.13

rectangle perimeter: 24

total: 49.13

The perimeter of the figure to the nearest hundredth. is 28.56 in.

To find the find the perimeter of the figure we'll add the sides of square and the circumference.

Perimeter of figure = 2 × Perimeter of semicircle + 2 × side of square + 2 × side length after excluding semicircle

Radius of semicircle = 4/2 = 2 in.

Perimeter of semicircle

Side of square = 6 in.

Side length after excluding semicircle = 6 - 4 = 2 in.

Perimeter of figure

= 2 × Perimeter of semicircle + 2 × side of square + 2 × side length after excluding semicircle

= 2 × 6.28 + 2 × 6 + 2 × 2

= 12.56 + 12 + 4

The teacher can choose four students to present the project out of seven in 35 different ways. This is calculated using the combination formula in combinatorics, a concept in mathematics.

The question involves the concept of combinatorics in mathematics, specifically the combination formula. The combination formula is used when the order of selection does not matter. In this case, the teacher is selecting 4 students out of 7 to present the project, and the order in which the students are chosen is irrelevant.

To calculate the number of ways the teacher can choose four students out of seven, we use the combination formula which is C(n, r) = n! / [(n-r)!r!], where:

Applying this to our scenario, n = 7 (total number of students), and r = 4 (students to be chosen to present). Plugging the values into the formula gives us C(7, 4) = 7! / [(7-4)!4!] = 35. So, there are 35 ways the teacher can choose four students to present the project.

The teacher can choose 4 students to present the project in 35 ways.

The teacher needs to choose 4 students out of a group of 7 to present the project.

To find the number of ways to choose 4 students from a group of 7, we use the combination formula.

The formula for combinations is C(n, r) = n! / (r! * (n-r)!), where

n is the total number of students and

r is the number of students to be chosen.

Substituting n = 7 and r = 4 into the formula, we get

C(7, 4) = 7! / (4! * (7-4)!) = (7 * 6 * 5 * 4 * 3 * 2 * 1) / (4 * 3 * 2 * 1 * 3 * 2 * 1) = 35.

Therefore, there are 35 ways for the teacher to choose 4 students to present the project.

By using the combination formula to calculate the number of unique ways a group can be formed, we find that a coach can divide her 9-player squad into three equal groups in 5600 ways.

The student's question is about a concept in mathematics called combinations. A combination is a selection of items without regard to the order in which they are selected. In this particular problem, the tennis coach is dividing her 9-player squad into three equal groups. The number of ways this can be done uses the formula for combinations (nCr) where n equals the total number of items (in this case, players) and r equals the number of items being chosen at a time (in this case, the number of players in each group).

First, the coach can choose the first trio from the nine players using the combination formula 9C3. The second trio is chosen from the remaining 6 players, so this uses the formula 6C3, and for the third trio, which is chosen from the remaining 3 players, the formula is 3C3. Multiplied out, 9C3 x 6C3 x 3C3 equals 280 x 20 x 1 which is 5600. Therefore, there are 5600 unique ways the coach can divide her 9-player squad into three 3-player groups with each player in only one group.

There are 720 different ways for 7 students to sit at a circular table for a debate, calculated using permutation principles by fixing one seat and arranging the remaining six students (6!).

The question asks about the number of different ways 7 students can sit at a circular table for a debate, which involves a mathematical concept called permutations. Since a circular arrangement means that the starting point is not fixed, we have to consider one position as fixed to avoid repeating identical seating arrangements caused by rotation. Therefore, with one student fixed, we have 6 seats left to arrange the remaining 6 students. This scenario is a permutation problem without repetition and can be calculated using the factorial operation (6!).
