Joseph was kayaking on the Hudson River. While looking at the Breakneck Ridge trail-head, he lost a whole bag of donuts. Joseph didn't realize he had lost it for fifteen minutes. That's when he turned back and started going in the opposite direction. When he found the bag, which was going at the speed of the Hudson's current, it was two miles from the Breakneck Ridge trail-head. What is the speed of the current in the Hudson River?

Answers

Answer:

8 miles per hour

Step-by-step explanation:

Actually pretty simple. It took 15 minutes for the bag to travel two miles from the Breakneck Ridge so it will be four miles per 30 minutes six miles per 45 minutes and 8 miles per hour.

Julia loves collecting baskets. Every month she adds two new baskets to her collection. In the month of March she has 60 baskets. She’s worried she will soon run out of room in her apartment to keep her baskets. Write an equation that represents the percent of change of her basket collection from the beginning of the year to the end of the year, then solve.

Answers

The linear function that represents the amount of baskets in the xth month of the year is given as follows:

The percentage of her collection that she needs to get rid of is of 3.85%.

Linear Function:-

The definition of a linear function is:

y = b + mx

In which the parameters of the equation are given as follows:

•b is the value of y when x=0

•m is the rate of change for each unit of x

Every month she adds 2 new baskets to her collection, hence the slope is of : m = 2

Then: y = b + 2x

From the March amount, when x = 3, y = 60, hence the intercept b is given as follows:

60 = b + 6

b = 54

Hence the equation is: y = 54 + 2x

At the end of the year (12 months) the amount of baskets that she will have is of:

y = 54 + 2 × 12 = 78

Hence, she has to get rid of 3 baskets, as 78 - 75 = 3, and the percentage is of:

p = 3/78 × 100% = 3.85%.

1 x 7 - 13 x 56 divided by 7 -5 x 500 is what?

Answers

Answer:  -2597

Step-by-step explanation: First, you multiply 1 x 7 to get 7, then subtract 13 from that, and multiply that by 56. Then you find what 7 -5 x 500 is, and divide it by the first part you got, to ger -2597. I'm sorry If I'm wrong .

Answer:

-2597

Step-by-step explanation:

Using PEMDAS, M would be multiplying so you you multiy 1x7 then times 56 then S is for subtraction so then you subtract 13, save that first set (1x7-13x56) to the side and now lets do the other set (7-5x500) first you would multiply it by the 500 and you get 3,500 then subtract it now get your two answers and divide it, then youll get -2597

I think...

The constant of Proportionality is 8.

What is constant of Proportionality?

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Step-by-step explanation:

A good way to remember how to do percentages is starting with 10% of overall.

Overall, 10% of the $50 would be $5
you just move the decimal from $50.00 to $5.00
moving it to the left once, for ten percent

Consider the 3-digit number which are written by using only the digits 1,2,3,4,5. How many of these have two equal digits and one different digit?

Answers

5 3-digit numbers that have three equal digits.

we need to apply the principle of inclusion-exclusion to account for the fact that some 3-digit numbers may be counted multiple times.

any 3-digit number that has three equal digits will be counted twice once as a 3-digit number with two equal digits and one different digit, and once as a 3-digit number with three equal digits.

There are 5 choices for the digit that is repeated, and 1 way to arrange the digits, so there are 5 3-digit numbers that have three equal digits.

Therefore, we need to subtract 5 from the total number of 3-digit numbers that have two equal digits and one different digit.

60 number are 3-digit numbers that have two equal digits and one different digit.

What is permutation and combination?

Permutation and combination are ways to arrange values in a set. In permutation the order of arrangement matters, but in combination the order of arrangement does not matter.

The given digits are,

1, 2, 3, 4, 5.

Since, to find the 3 digits numbers which are written by using given digits, and have two equal digits and one different digit,

Here order of arrangement matters.

Use permutation formula,

From 5 digits, 3 are chosen,

Ways of arrangement = ⁵P₃  

= 5! / (5-3)!

= 5! / 2!

= 5 x 4 x 3 x 2! / 2!

= 60

There are total 60 different ways, in which numbers can be arranged.

The vertical distance between the points A and B are D = 2 units

What is the distance between two points?

Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )

The distance from A to B is the same as the distance from B to A

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

This formula is used to find the distance between any two points on a coordinate plane or x-y plane

Given data ,

Let the distance between 2 points be represented as D

Now , let the first point be A ( -1.5 , 1.25 )

Let the second point be B ( -1.5 , -0.75 )

The distance D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

And , the vertical distance between A and B = |y-coordinate of A - y-coordinate of B|

So , the value of D = |1.25 - (-0.75)|

D = 2 units

Hence , the vertical distance is D = 2 units

Answers

Answer:
14 hours
Step-by-step explanation:
Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday.
Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:
4x + 2(x + 2)= 76
4x+ 2x + 4 = 76
6x=72
x = 12
Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x
+ 2. Thus, that is 12 + 2 = 14 hours.

Step-by-step explanation:

You want the number of teeth that have touched when a 12-tooth gear and an 8-tooth gear turn until they have the same relative position as when they started.

Least common multiple

The least common multiple (LCM) of 8 and 12 is the smallest integer that is a positive integer multiple of both these numbers. That value is ...

  24 = 8·3 = 12·2

It is often found quickly by making use of your knowledge of multiplication tables.

How to find it

The LCM can be found by looking at the unique factors of the numbers, taking each to the highest of the powers:

  8 = 2³

  12 = 2² × 3

Among the factors 2 and 3, the highest powers are 2³ and 3¹, so ...

  2³ × 3¹ = 24

is the LCM.

The LCM is also the product of the numbers, divided by their greatest common factor (GCF):

  LCM(8, 12) = 8·12/4 = 24

The problem statement is telling you to look for the same number in the two right columns of the table. That number is 24. It goes in the blanks at the bottom.
