Jamie can paint a wall in 54 minutes Together Connie and Jamie can paint the same wall in 36 minutes How long would it take Connie to paint the same wall by herself

Answers

Answer:

The answer is 108

Step-by-step explanation:

I did this for my exam got 100

Together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.

We have given that,

John can paint 1/54 of a wall in 1 minute.

James can paint 1/36 of a wall in 1 minute.

What is the formula for total wall paint in one minute?

Total wall paint of both in one minute is calculated by adding the both the paint in one minute it gives us the total paint in one minute

Therefore ,total wall paint in one minute =1/54 + 1/36

So if they work together, they can both paint 1/54 + 1/36 of a wall in 1 minute.

1/54 + 1/36 = 2/108 + 3/108 = 5/108 = 0.04629.

Therefore,together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.

Step-by-step explanation:

did the test on edge

The probability that more than 30% of the owners in the sample pay for someone to walk their dog is option c. 0.561.

Calculation of the probability:

Since 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog

= P> ( 0.30 - 0.31) / √0.31 (1 - 0.31)/ 50

= P(z > - 0.1530)

= 0.5608

= 0.561

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

We have to given that;

The point is,

⇒ (- 3, - 3)

Now, We know that;

The rule of reflection after across the y - axis is,

⇒ (x, y) = (- x, y)

Thus, The point which is a reflection of (-3,-3) across the y-axis is,

⇒ (x, y) = (- x, y)

⇒ (-3, -3) = (- (-3), -3)

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]D = 25 + 0.3X[/tex]

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

[tex]D = b + mx[/tex]

Where

[tex]b = D\ intercept[/tex]

[tex]m = slope[/tex]

By comparing: [tex]D = 25 + 0.3X[/tex] to [tex]D = b + mx[/tex]

[tex]b = 25[/tex] and [tex]m = 0.3[/tex]

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in [tex]D = 25 + 0.3X[/tex]

[tex]D = 25 + 0.3 * 5[/tex]

[tex]D = 25 + 1.5[/tex]

[tex]D = 26.5[/tex]

The cost of 5 miles is $26

Answers

Answer:

Culture has a significant impact on heroes. For starters, it influences how a person or character perceives a particular situation or idea, as well as their point of view on a variety of ideas and topics. Next, it has an impact on how the hero is portrayed in the story. Third, it influences how a character reacts to an idea or situation.

Culture has an impact on heroes. We see an example of this in 'Black Ships Before Troy,' where in Achilles' culture, to be a hero, you must be brave and fight. This is also evident in 'Heart of a Samurai,' where Manjiro's culture dictates that in order to be a hero, you must provide for your family.
