A jet moving at constant speed traveled 6,600 km in 3 hours. What was the speed of the jet?

Answers

Answer 1

Answer:

Answer:

The speed of the jet is $2,200(km)/(h)$

Step-by-step explanation:

The speed traveled by the jet can be found using the relationship between distance and time. Because the problem gives the values for distance and time, they must be replaced in the equation and in this way the requested speed will be found.

1. Write the general equation for the speed:

$Speed=(Distance)/(Time)$

2. Replace the values of distance and time on the general equation for the speed and make the mathematical operations:

$Speed=(6,600km)/(3hours)$

$Speed=2,200(km)/(h)$

Therefore the speed of the jet is $2,200(km)/(h)$

Answer 2

Answer: speed=distance ÷ time
speed=6600 ÷3
speed=2200km/h

If a sprinkler waters 1/8 of lawn in 1/4 hour, how much tome will it take to water the entire lawn?

Answers

Answer:

1/8 of the lawn in 1/4 of an hour. That mean you would need a whole hour to do 4/8 or 1/2 of the lawn. So you would need two hours to do the whole lawn.

Step-by-step explanation:

Answer:

2 hours or you can say 120 minutes

Step-by-step explanation:

1/4 of an hour equals 15 minutes

1/8 = 15 minutes

4/8 = 1 hour = 60 minutes

8/8 = 2 hours = 120 minutes

Patricia scored 80% on a math test. She missed 4 problems. How many problems were on the test?

Answers

Answer: There are 20 problems on the test.

Step-by-step explanation:

Since we have given that

Patricia scored 80% on a math test.

She missed 4 problems.

So, 20% of the math test is equal to 4 problems.

Let the total number of problems on the test be x

According to question,

$(20)/(100)* x=4\n\nx=(100)/(20)* 4\n\nx=20$

Hence, there are 20 problems on the test.

There would be exactly twenty problems on the test for her to be able to get 80%.
You know it can't be ten because then that would make it 60% not 80% but if you add the first number of the percentage (8) and multiply it by two it will get you 16 then if you add 4 to that that would make it 20 and 16/20 equals 80%

You have a can that is in the shape of a cylinder. It has a volume of about 1,738 cubic centimeters. The height of the can use 23 centimeters. What is the approximate length of the radius? Use 3.14 for pi

Answers

Answer:

~8.7

Step-by-step explanation:

So we know that the formula for volume is 3.14 * r^2 * h.

So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.

The square root of 75.6 is ~ 8.7

Answers

3 times 36 equals 10836 + 36 + 36= 108

36 times 3 equals to 108 because 3*6=18 and 3*3=9. You use the 1 from 18 and add it to the 9 which makes 10 which also makes 108.

If three times Linda's age is decreased by 36,the result is twice Linda's age.How old is linda

Answers

x=lindas age
3 times lindas age (3 time x or 3x) is decreased by 36 (-36), the result (=) is twice lindas age (2 times x or 2x)

now we have
3x-36=2x
subtract 2x
x-36=0
add 36
x=36
age=36

Help please?Describe a situation that matches the equation. 34 = g + 25

A: The temperature on Monday was 25 degrees below zero and on Tuesday the temperature got up to 34 degrees. What was the increase in temperature between Monday and Tuesday?

B: The eighth-grade class has 34 students. The year before, when the students were in seventh grade, there were 25 students. How many students were added between seventh and eighth grade?

C: A person bikes 34 miles on Monday and 25 miles on Tuesday. How many miles total did the person bike?

D: Jack has 25 marbles. Mary gives him 34 marbles. How many marbles does Jack have?

Answers

Answer:

Option B matches the equation

Step-by-step explanation:

Equation: 34 = g + 25

A:Since we are given that The temperature on Monday was 25 degrees below zero So, in given equation there should be -25 in place of 25

So, It does not matches the equation

B: The year before, when the students were in seventh grade, there were 25 students.

Let g be the no. of students added between seventh and eighth grade

So, Total students = 25+g

We are given that The eighth-grade class has 34 students.

So, equation becomes : 34=g+25

It matches the equation.

C :A person bikes 34 miles on Monday

He bikes 25 miles on Tuesday.

So, Total miles =25+34

So, It does not matches the equation

D: Jack has 25 marbles.

Mary gives him 34 marbles.

Total marbles = 25+34

So, It does not matches the equation

Hence Option B matches the equation

Answer:

The answer is B!

Step-by-step explanation:

The equation and the equation from scenario B are both, when simplified, g = 9.
