[tex]\frac{4}{5}[/tex] is the ratio form a proportion with [tex]\frac{16}{20}[/tex]

Step-by-step explanation:

Proportion states that the two fraction or ratios are equal.

i.e, [tex]\frac{a}{b} = \frac{c}{d}[/tex]

Given the ratio [tex]\frac{16}{20}[/tex]

To find the proportion of this ratio forms.

[tex]\frac{16}{20}[/tex]

Divide top and bottom by 4 , we have;

[tex]\frac{\frac{16}{4} }{\frac{20}{4} }[/tex]

Simplify:

[tex]\frac{4}{5}[/tex]

therefore, a ratio form a proportion with [tex]\frac{16}{20}[/tex] is, [tex]\frac{4}{5}[/tex]

Option D, 4/5 forms a proportion with 16:20.

To determine which ratio forms a proportion with 16:20, we must find a ratio equivalent to 16:20.

We start by simplifying 16:20. Both 16 and 20 can be divided by their greatest common divisor, which is 4:

16 ÷ 4 = 4

20 ÷ 4 = 5

This gives us the simplified ratio of 4:5. Now, we need to check which of the given options matches 4:5.

4/10: When simplified, 4:10 becomes 2:5, which is not equal to 4:5.

32/50: When simplified, 32:50 becomes 16:25, which is not equal to 4:5.

8/12: When simplified, 8:12 becomes 2:3, which is not equal to 4:5.

4/5: This ratio is already simplified and equal to 4:5.

Therefore, the ratio 4:5 forms a proportion with 16:20.

Correct Question

Which ratio forms a proportion with 16:20 ?      

A. 4/10    

B.  32/50  

C.  8/12    

D. 4/5

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.

To determine the number of feet per second a squirrel can run, observe its speed and measure the distance it covers in a given time. Mark a short distance on the ground, start a timer as the squirrel begins running, stop the timer when the squirrel reaches the end, and divide the distance by the time to calculate the speed.

To determine the number of feet per second a squirrel can run, you can observe its speed and measure the distance it covers in a given time. Here are the steps:

For example, if the squirrel covers 10 feet in 2 seconds, its speed would be 10/2 = 5 feet per second.

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 n th term of an arithmetic sequence is

[tex]t_{n}[/tex] = [tex]t_{1}[/tex] + (n - 1)d

given [tex]t_{1}[/tex] = 3 and [tex]t_{2}[/tex] = 10, then

[tex]t_{2}[/tex] = 3 + d = 10 ⇒ d = 10 - 3 = 7

[tex]t_{n}[/tex] = 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][2[tex]t_{1}[/tex] + (n - 1)d ]

                        = [tex]\frac{n}{2}[/tex][(2 × 3) + 7(n - 1) ]

                        = [tex]\frac{n}{2}[/tex](6 + 7n - 7 )

                        = [tex]\frac{n}{2}[/tex](7n - 1)

We have m = 4/5 and the point (7, -9). Substitute:

Equation of the line is a way of representation of the line in a algebraic from with point which form the line in the coordinate system and the slope. Thus the equation of the line passing through the point (7,-9) having the slope 4/5 is,

[tex](y-7)=\dfrac{4}{5} (x+9)[/tex]

Hence, the option 2 is the correct option.

The line passes through the point (7,-9).

The slope of the line is 4/5.

Equation of the line is a way of representation of the line in a algebraic from with point which form the line in the coordinate system and the slope.

The standard form of the equation of the line can be given as,

[tex](y-y_1)=m (x-x_1)[/tex]

Here m is the slope of the line.

Thus, the equation of the line passes through (7,-9) having the slope 4/5 can be given as,

[tex](y-y_1)=m (x-x_1)[/tex]

Put the values,

[tex](y-7)=\dfrac{4}{5} (x-(-9))[/tex]

[tex](y-7)=\dfrac{4}{5} (x+9)[/tex]

The equation in standard form that represents the relationship between Fahrenheit (F) and Celsius (C) is 5F + (5/9)(F - 32) = 39.

In order to represent the relationship between Fahrenheit (F) and Celsius (C) in standard form, we can use the conversion formula:

C = (5/9)(F - 32)

Given the equation 5F + C = 39, we can substitute the value of C from the conversion formula into the equation:

5F + (5/9)(F - 32) = 39

Simplifying the equation further:

45F + 5(F - 32) = 351

45F + 5F - 160 = 351

Combine like terms:

50F - 160 = 351

Add 160 to both sides:

50F = 511

Divide both sides by 50:

F = 10.22

Therefore, the equation in standard form that represents the relationship between F (degrees Fahrenheit) and C (degrees Celsius) is 5F + (5/9)(F - 32) = 39.

B) 2700 + 400 = 3100

  the inequality would change to:

  5000 - 3100 = 1900 points needed

The student needs to accumulate an additional 2300 points to reach the 5000-point requirement for a gift card from the bank. They currently have 2700 points.

Calculating Points Needed for a Reward

To calculate how many more points a student needs to earn a gift card from the bank, we need to subtract the points the student already has from the required points for the gift card. The student currently has 2700 points and needs at least 5000 points in total. If we subtract the current points from the required points, we have:

Required points for the gift card: 5000 points

Current points: 2700 points

Points needed: 5000 points - 2700 points = 2300 points

The student needs an additional 2300 points to earn a gift card from the bank.

While accumulating points, a student might consider if they could benefit from a very convenient credit card that offers a free Rewards program, unsurpassed card protection, free PhotoCard, free Purchase Cover, personal customer service, and wide acceptance.

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
