What is 5 1/2% tax on $20?

Answers

Answer 1

Answer: 5.5 move decimal place over twice 20*.055 =$1.1 in sales tax

Answer 2

Answer: 5 1/2 percent must be converted to decimal form first to calculate immediately the value of 5 1/2 percent of $20. 5 1/2 percent over 100 percent is equal to 0.055. The product therefore is equal to 0.055*$20 equal to $1.1. The final answer is $1.1. The unit $ remains the same

Answers

Answer:

x = $(17)/(3)$

Step-by-step explanation:

$(10)/(x-4)=6\n\n$

10 = 6*(x -4)

10 = 6*x - 6*4

10 = 6x - 24

Add 24 to both sides

10 + 24 = 6x - 24 + 24

34 = 6x

6x = 34

Divide both sides by 6

6x/6 = 34/6

x = $(17)/(3)$

A basketball player has already scored 56 points in a game. The team record for points in a game is 72. Which equation would allow you to find out how many more points the player needs to tie the record?a. 72 + x = 56
b. 56 − 72 = x
c. 56 + x = 72
d. 56 + 72 = x

Answers

C. 56 + x =72 because the team player already scored 56 points you would need to add an unknown amount of points in this case x to find out how many points you need in order to reach 72 points and if you are curious how many points you need in order to get to 72 you need 16 points.

Answer:

C. 56 + x =72

A bee flies at feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for minutes, and then flies directly back to the hive at feet per second. It is away from the hive for a total of minutes. a. What equation can you use to find the distance of the flowerbed from the hive? b. How far is the flowerbed from the hive?

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

A bee flies at 12 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 8 feet per second. It is away from the hive for a total of 18 minutes. A. Write the equation. Let d be the distance of the flowerbed from the hive. B. how far away is the hive from the flower bed.

First we need to calculate the time taken by the bee to fly to a flowerbird to its hive using the formula;

Speed = Distance/Time

Time = Distance/Speed

If a bee flies at 12 feet per second directly to a flowerbed from its hive, then the time taken by the bee is expressed as;

t1 = d/12 ....... 1

If the bee then flies directly back to the hive at 8 feet per second, the time taken by the bird will be:

t2 = d/8 ....... 2

Total time taken by the bee to and fro will be the sum total of both times;

t1+t2 = d/12+d/8

t11+t2 = 2d+3d/24

t1+t2 = 5d/24 ........ 3

If the bee stays at the bee stays at the flowerbed for 14 minute and away from the hive for 18minutes, the total time used by the bird during the journey will be 18-14 = 4 minutes

converting 4 minutes to seconds

4 minutes = 4*60 = 240seconds

The equation that can be used to find the distance of the flowerbed from the hive is gotten by equating equation 3 to the total time used by the bird during the journey i.e;

5d/24 = 240

5d = 24*240

5d = 5760

b) To know how far is the flowerbed from the hive, we will solve the resulting equation in a for the value of d as shown

Given 5d = 5760

Divide both sides by 5

5d/5 = 5760/5

d = 1152ft

Hence the distance of the flowerbed from the hive is 1152ft

Nora is running a race that is 26.2 miles. She is running at a speed of 18 miles per hour. She has completed 3/4 of the race. How much longer will it take Nora to finish the race?

Answers

Answer:

The answer to your question is 6.55 mi

Step-by-step explanation:

Data

Length of the race = 26.2 mi

speed = 18 mi/h

3/4 of the race have been ran

Process

1.- Calculate 3/4 of 26.2

26.2(3/4) = 78.6/4

= 19.65 mi

2.- Calculate the distance she needs to run to finish the race

= 26.2 - 19.65

= 6.55 mi

3.- Conclusion

She needs to run 6.55 mi to finish the race.

Final answer:

Nora will take approximately 21.85 minutes to finish the race.

Explanation:

To find out how much longer it will take Nora to finish the race, we need to first calculate the distance she has already completed. Since she has completed 3/4 of the race, we can calculate it by multiplying the total distance of the race (26.2 miles) by 3/4.

Distance completed = 26.2 miles * 3/4 = 19.65 miles

Next, we need to calculate how much distance Nora has left to cover. Since the total distance of the race is 26.2 miles and she has completed 19.65 miles, the distance left is:

Distance left = 26.2 miles - 19.65 miles = 6.55 miles

Finally, we can calculate the time it will take Nora to finish the race by dividing the remaining distance by her speed:

Time to finish = Distance left / Speed = 6.55 miles / 18 miles per hour = 0.364 hours (or approximately 21.85 minutes)

Therefore, it will take Nora approximately 21.85 minutes to finish the race.
