Roni and Allie are mowing the grass at the soccer field. Roni has a riding lawn mower and can mow the field in 30 minutes. Allie is pushing a lawn mover and can mow the field in 75 minutes. If Roni and Allie work together to mow the field, what part of the field would Roni mow?

Answers

Answer 1

The part of the field would Roni mow will be 4 3/7 of the field.

How to calculate the fraction?

To find out what part of the field Roni would mow if he and Allie worked together to mow the field, you would need to calculate their combined rate of mowing.

You can find the combined rate by adding the rates of each person working alone:

Combined rate = (Roni's rate) + (Allie's rate)

Combined rate = (1/30 hour) + (1/75 hour) = (5/150) + (2/150) = (7/150) hour

Then divide the rate of Roni by the combined rate to find the proportion of the field that Roni would mow:

(Roni's rate) / (Combined rate) = (1/30 hour) / (7/150 hour) = (30/7) / 1 = 4.2857142857142856

So Roni would mow about 4.29 or roughly 4.3/7 of the field if he and Allie worked together.

How many units down does susan need to move to get to the fourth point on the number line a. 1/2 b. 3/2 c. 2 d. 4 e. 6

Answers

Answer:

e. 6

Step-by-step explanation:

Hello there!, since there is no prior information concerning the activities performed by Susan, I will explain what a number line is and try as much as possible to answer your question from the definition.

A number line is a line on which integers are usually drawn as points separated by a uniform distance. This way, the number line makes addition and subtraction easier, which is very useful when you want to teach someone these operations.

Now, let assume Susan starts from 0 on the number line, to get to the fourth point, Susan needs to move 4 blocks, where each block contains 10 units.

Now, let's assume that Susan is at the third block and the fourth unit, it will take Susan an additional 6 units to get to the fourth point.

NOTE: The solution to this question was provided based on assumption since no much information was given in the question.

A boat which moves a 15 miles per hour without a current goes 36 miles upstream and 36 miles back in 5 hours. Find the speed of the current

Answers

Answer:

3 mph

Step-by-step explanation:

UPSTREAM:

distance = 36 miles ;

Speed = 15-c mph ;

TIME, t = distance / speed = 36/(15-c)

Downstream :

distance = 36 miles ;

speed = 15+c mph ;

time, t = 36/(15+c)

upstream time + downstream time = 5 hrs

36/(15-c) + 36/(15+c) = 5

36(15+c) + 36(15-c) = 5(15-c)(15+c)

1080 = 5(225 - c²)

1080 / 5 = 225 - c²

216 = 225 - c^2

216 - 225 = c²

-9 = c²

Do the ratios 4/2 and 10/5 form a proportion? Yes or no

Answers

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

[tex]\frac{4}{2}[/tex]    [tex]\frac{10}{5}[/tex]

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

If you have any questions or concerns feel free to message me.

Yes the ratios 4/2 and 10/5 form a proportion.
