Step-by-step explanation:

A scale drawing is a larger or smaller version of an object. To find the dimensions of the new drawing, multiply each measurement by the scale factor. The scale factor here is 5/2 or 2.5.

12(2.5)=30 ft

3(2.5)=7.5 ft

Answer:

40 students

Step-by-step explanation:

Lets multiply:

5:3 = 10:6 = 20:12 = 25:15

Since 25 is 10 more than 15, these are the actual numbers we need.

25 + 15 = 40 students.

Answer:

If the ratio is 5:3 boys to girls and there are 10 more boys than girls, there would be 15 girls and 25 boys, for a total of 40 people.

Step-by-step explanation:

To solve the ratio, we need to set up a proportion and assign a variable to solve for.  In this case, we can make 'x' the number of girls and 'x+10' the number of boys.  We know that the ratio of boys to girls is 5 to 3, so we can set up a proportion where 5/3 = (x+10)/x.  In order to solve a proportion, we would cross-multiply and divide in order to get a two-step equation to solve for the variable.  When we cross-multiply, we get 5x=3(x+10), or 5x=3x + 30.  Using inverse operations, first subtracting the '3x' from both sides to get 2x=30, and then dividing both sides by 2 to get x=15.  Remember, that 15 represents the number of girls.  The number of boys is equal to  'x+10' or 15 +10=25.  Then the total number of people is 15+25=40.

Answer:

Area of plane surface of cylinder = 2772 sq.cm.

Step-by-step explanation:

Let r be the radius and h be the height of the cylinder.

Curved Surface Area = 1848 sq.cm

2πrh = 1848

2×[tex]\frac{22}{7}[/tex]×rh = 1848

rh = 1848 × [tex]\frac{7}{22}[/tex] × [tex]\frac{1}{2}[/tex]

rh = 294

Sum of radius and height = 35

r + h = 35 --- (1)

Now,

r - h = [tex]\sqrt{(r+h)^{2}-4rh }[/tex]

= [tex]\sqrt{35^{2}-4(294) }[/tex]

= [tex]\sqrt{1225-1176}[/tex]

= [tex]\sqrt{49}[/tex]

= 7

r - h = 7 --- (2)

Adding (1) and (2),

2r = 42

r = 21  cm.

Area of the plane surface = 2 × π[tex]r^{2}[/tex]

= 2 × [tex]\frac{22}{7}[/tex] × 21 × 21

= 2772 sq.cm.

To calculate the plane surface area of a cylinder, subtract the area of the two circular bases from the curved surface area. Use the given formula and equations to find the radius and height, then calculate the area of one circular base. Finally, subtract the area of the bases from the curved surface area to find the plane surface area.

To calculate the plane surface area of a cylinder, we need to subtract the area of the two circular bases from the curved surface area.

The formula for finding the curved surface area of a cylinder is given as:

CSA = 2πrh

So, the curved surface area is 1848 cm² and the sum of the radius and height is 35 cm. We can use these values to find the radius and height of the cylinder.

Solving the equation 2πrh = 1848 and r + h = 35 simultaneously will give us the values of r and h.

Once we have the values of r and h, we can calculate the area of one circular base using the formula Area = πr². Finally, we can calculate the plane surface area by subtracting the area of the two circular bases from the curved surface area.

If we have a triangle with side lengths a,b,c then we can write this compound inequality

b-a < c < b+a

If we knew the value of a and b, then we can find a range for c.

In our case, a = 5, b = 12, c = n, so,

b-a < c < b+a

12-5 < n < 12+5

7 < n < 17

The value of n is between 7 and 17. The value of n cannot equal 7, and it also can't equal 17 either.

Final Answer for problem 15 is choice C) 7 < n < 17

Final answer:

To find the number of men at the college, divide the total number of students by the sum of the parts in the ratio (6+5) and then multiply by the number of parts for men (6/11). The answer is 1920 men at the college.

Explanation:

To find the number of men at the college, we need to use the ratio of men to women. The ratio is given as 6 to 5, which means there are 6 parts for men and 5 parts for women.

To calculate the number of men, we divide the total number of students by the sum of the parts in the ratio (6+5).  

So, the number of men is (6/11) * 3520 = 1920. Therefore, there are 1920 men at the college.

Step-by-step explanation:

The orthocenter is only outside of a triangle when the triangle is obtuse. The only obtuse triangle shown is the 25-45-110 triangle.

The orthocenter is only outside of a triangle when the triangle is obtuse. The only obtuse triangle shown is the 25-45-110 triangle.

In a triangle, the orthocenter is the point where the altitudes of the triangle intersect.

Altitudes are lines drawn from each vertex of the triangle perpendicular to the opposite side.

In some cases, the orthocenter can be located outside of the triangle.

One example of a triangle where the orthocenter is located outside of the triangle is an obtuse triangle.

In an obtuse triangle, one of the angles is greater than 90 degrees.

When you draw the altitudes, they will intersect outside the triangle, forming the orthocenter.

For instance, consider a triangle with angle measures of 100 degrees, 40 degrees, and 40 degrees. When you draw the altitudes, you will find that they intersect outside the triangle. Thus, an obtuse triangle can have an orthocenter located outside of the triangle.

Step-by-step explanation:

Given : Lanny’s credit card has an APR of 33%, calculated on the previous monthly balance. His credit card record for the last 7 months is shown in the table below.

To find : What is the new balance at the end of month 7?    

Solution :  

From the table, the information of 7 month

Previous balance = $74.33

Payment = $91.98

Unpaid balance = Previous balance - Payments

                          = $74.33 - $91.98

Unpaid balance  = -$17.65

Finance charge = $2.04

New charges = $99

New balance =  Unpaid balance + finance charge + new charges

New balance =  -$17.65 +$2.04+ $99

New balance =$83.39

Answer:

The distance from Old Towne to Bridgeway is 15 11/12 miles.  

Step-by-step explanation:

In order to find the distance from Old Towne to Bridgeway, we need to subtract the posted distances for these two cities.  Since Old Towne is 36 1/3 miles away and Bridgeway is 52 1/4 miles away, we need to subtract 36 1/3 from 52 1/4.  We cannot subtract fractions with unlike denominators, so we need to find the lowest common denominator of 3 and 4, which is 12.  When we make the fraction of 1/4 over a denominator of 12 we get 3/12 and when we convert 1/3 to a fraction with a denominator of 12, we get 4/12.  Since we can not subtract 4 from 3, we need to take one away from 52 and add it to our fraction to become 51 15/12.  Subtracting 51 15/12 - 36 4/12 = 15 11/12 miles.

Final answer:

The distance from Old Towne to Bridgeway is calculated by subtracting the distance to Old Towne from the distance to Bridgeway, resulting in 15 11/12 miles.

Explanation:

To determine the distance between Old Towne and Bridgeway, we subtract the distance from the starting point to Old Towne from the distance to Bridgeway. Old Towne is 36 1/3 miles away, and Bridgeway is 52 1/4 miles away. We must first convert these mixed numbers to improper fractions to do the subtraction.

Convert 36 1/3 to an improper fraction: (36 × 3) + 1 = 108 + 1 = 109/3.

Convert 52 1/4 to an improper fraction: (52 × 4) + 1 = 208 + 1 = 209/4.

Find a common denominator to subtract the fractions. The common denominator for 3 and 4 is 12. Thus, convert both fractions to twelfths: 109/3 becomes 436/12, and 209/4 becomes 627/12.

Subtract the distance to Old Towne from the distance to Bridgeway: 627/12 - 436/12 = 191/12.

Convert 191/12 back to a mixed number to find the distance: 191 ÷ 12 = 15 with a remainder of 11, so the distance is 15 11/12 miles.

Therefore, the distance from Old Towne to Bridgeway is 15 11/12 miles.

Answer:

If both computers are working together, it will take 24 minutes to do the job

Step-by-step explanation:

It is given that,

There are two computers.The slower computer can send all the company's email in 60 minutes.

The faster computer can complete the same job in 40 minutes

To find the LCM of 40 and 60

LCM (40, 60) = 120

To find efficiency of 2 computers

Let x be the efficiency of faster computer and y be the efficiency of faster computer

x = 120/40 = 3

y = 120/60 = 2

then, x + y = 3 + 2 = 5

Therefore efficiency of both the computer work together = x + y =5

To find the time taken to work both the computer together

time = 120/5 = 24 minutes

The slower computer works at a rate of 1/60 of the task in a minute, and the faster computer works at a rate of 1/40 per minute. When they work together, they perform 1/24 of the task per minute, and hence, they would complete the task in 24 minutes.

The subject of this question is Mathematics, specifically focused on the topic of rates and time. The slower computer sends all the company's email in 60 minutes, which implies it can perform 1/60 of the task per minute. The faster computer can send all the company's email in 40 minutes, inferring that it works at a rate of 1/40 of the task per minute.

When both computers are working together, their rates of working are added together, therefore they perform (1/60) + (1/40) = 1/24 of the task per minute. The reciprocal of this fraction gives the total time it would take both computers to complete the task, i.e., 24 minutes when working together. So, it would take 24 minutes for both computers to send all the company's emails if they work together.

Answer:(-2,8) (-1,5) (0,2) (1,-1) (2,-4)

Step-by-step explanation:

This question can be solved by using simple algebra to set up equations based on the given conditions. We found that the two numbers are 38 and 26.

To discover the two numbers, we will use a mathematical approach based on the problem. If we denote the larger number as 'x' and the smaller number as 'y', we have two equations based on the statement: 'x + y = 64' and 'x - y = 12'. You can solve this system of equations by adding these two equations together to eliminate 'y'. This operation will give you the result '2x = 76'. Upon dividing both sides of the equation by 2 you find that 'x = 38'. To find 'y', you subtract 38 from 64 based on the summation equation, yielding the result 'y = 26'. So, the two numbers are 38 and 26.

https://brainly.com/question/35467992

#SPJ2

The sum of the two numbers is 64, and the difference is 12. By setting up and solving a system of equations, we find that the two numbers are 38 and 26.

To find the two numbers, let's set up a system of equations:

Let x be one of the numbers, and y be the other number.

We can write two equations based on the given information:

x + y = 64 (sum of two numbers is 64)

x - y = 12 (difference of two numbers is 12)

To solve this system of equations, we can use the method of substitution or elimination.

Using the method of elimination, we can add the two equations:

(x + y) + (x - y) = 64 + 12

2x = 76

x = 38

Substituting the value of x into one of the equations:

38 + y = 64

y = 26

Therefore, the two numbers are 38 and 26.
