A ferry traveled 1/6 of the distance between two ports in 3/7 hour. At this rate, what fraction of the distance between the two ports can the ferry travel in one hour?

Answers

(1/6) / (3/7) = x / 1......1/6 distance to 3/7 hr = x distance to 1 hr
cross multiply
(3/7)(x) = (1/6)(1)
3/7x = 1/6
x = (1/6) / (3/7)
x = 1/6 * 7/3
x = 7/18 <=== 7/18 of the distance in 1 hr

Two numbers have a distance of 5 units from 0 on a number line. The numbers can be graphed on the number line as points A and B.

Drag and drop the labels to the correct positions on the number line.

Answers

Drag A to negative 5 and B to positive 5.

Answer:

Point A is labeled at x=-5 and point B is labeled at x=5.

Step-by-step explanation:

It is given that two numbers have a distance of 5 units from 0 on a number line.

Let the unknown number be x.

Case 1: x is 5 units less than 0.

[tex]x=0-5[/tex]

[tex]x=-5[/tex]

The point A is labeled at x=-5.

Case 2: x is 5 units more than 0.

[tex]x=0+5[/tex]

[tex]x=5[/tex]

The point B is labeled at x=5.

Which graph represents the equation y=13x−4 ?

Answers

Answer:  The correct option is graph (A).

Step-by-step explanation:  We are given to select the graph that represents the following linear equation :

[tex]y=\dfrac{1}{3}x-4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Comparing with the slope-intercept form y = mx + c of a straight line, we see that

the slope of the line (i) is [tex]m=\dfrac{1}{3},[/tex] and y-intercept, c = -4.

Also, we know that the slope of a line passing through the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

Graph (A) :  

The points (0, -4) and (3, -3) lies on the line. So, its slope will be

[tex]m=\dfrac{-3-(-4)}{3-0}=\dfrac{1}{3},[/tex]

the point where the line crosses the y-axis is (0, -4).

That is, y-intercept, c = -4.

Since the slope and y-intercept of graph (A) is same as that of line (i), so this option is CORRECT.

Graph (B) :  

The points (0, -2) and (3, -3) lies on the line. So, its slope will be

[tex]m=\dfrac{-3-(-2)}{3-0}=-\dfrac{1}{3},[/tex]

Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.

Graph (C) :  

The points (0, -4) and (-3, 3) lies on the line. So, its slope will be

[tex]m=\dfrac{3-(-4)}{-3-0}=-\dfrac{7}{3},[/tex]

Since the slope of graph (C) is not same as that of line (i), so this option is NOT CORRECT.

Graph (D) :  

The points (-4, 0) and (-3, 3) lies on the line. So, its slope will be

[tex]m=\dfrac{3-0}{-3-(-4)}=\dfrac{3}{1}=3,[/tex]

Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.

Thus, graph (A) is the correct option.

Answers

cost of the meal is 60, the number of friends is x, and the tip is 1+x

Answer:

1) Option c

2) Option b

3) Option a

Step-by-step explanation:

Given : The expression 60(1+x) represents the total bill including the tip.

To find : What do the different parts of the expression represent?

Match each expression to the correct description.

1) Cost of meal __

2) Tip percentage __

3) Number of friends __

Solution :

The expression represents the total bill including the tip is 60(1+x).

When we see the expression,

The cost of the mean is always fixed.

So, Cost of the meal is 60.

Number of friends is unknown.

So, Number of friends is 'x'.

The tip percentage is given by '1+x'.

Slope=

Answers


The two points are (1,30) and (7,55). Slope = the change in y/the change in x. Slope is -25/-6, which simplifies to 4.2.
(7,55)(1,30)
slope = (55-30) / (7-1)
slope = 25/6
slope = 4.2

Solve 6x-17= k for x

Answers

Basically, the question is asking us to isolate x. We can do this by first subtracting 17 from both sides. This gives us 6x = k + 17. Now, all that is left to do is divide both sides by 6, giving us x = 1/6x + 17/6. Therefore, since the answer cannot be simplified any further, the answer to your question is x = 1/6x + 17/6. Hope this helps and have a fantastic day!

Answers

Culture in petri dish A is 1.08 x 10^15 and culture in petri dish B is 2.7 X 10^11. To determine how much greater petri dish A is from petri dish b, you must divide petri dish A by petri dish b. When you divide the two numbers, the answer is 4,000. The number of bacteria in petri dish A is four thousand times greater than the number of bacteria in petri dish B.

Answer:

Sean spelled 13 out of 20 words correctly on his srelling test. Write his test score as a percent.

Answers

Sean has scored a score of 65% on his spelling test
percent means parts out of 100
x%=x/100


so 13/20=x%
13/20=x/100
multiply both sides by 100 to find x
1300/20=x
130/2=x
65=x

his score as a percent is 65%

What is combination?

Combinations are also referred to as selections. Combinations implies the selection of things from a given set of things. In this case, we intend to select the objects.

Combination formula:

ⁿCr = n! / ((n – r)! r!)

n = the number of items.

r = how many items are taken at a time

The information will be illustrated as:

= 26! / (26 - 6)! 6!

= 26! / 20!6!

= 230230
