Distance between points (-1.5, 1.25) and (-1.5, -0.75) is 2

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

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

Answer:

its 4-6

Step-by-step explanation:

Step-by-step explanation:

the motorcyclist starts x hours after the bus.

it takes the motorcyclist 1.5 hours to meet the bus the first time, 6 hours to reach B, rest 1 hour and go another 2 hours before the bus arrives at B.

so, the bus needs

x + 9 hours to reach B.

x + 1.5 hours for 150 km (for the first meeting with the motorcyclist).

the speed of the bus is 600/(x + 9) km/h or 150/(x + 1.5) km/h.

so,

600/(x + 9) = 150/(x + 1.5)

4/(x + 9) = 1/(x + 1.5)

4(x + 1.5)/(x + 9) = 1

4(x + 1.5) = x + 9

4x + 6 = x + 9

3x + 6 = 9

3x = 3

x = 1

the motorcyclist starts 1 hour after the bus.

the speed of the bus is

600/(x + 9) = 600/(1 + 9) = 600/10 = 60 km/h

when the motorcyclist is starting its return trip, he is 7 hours after his start, and the bus is 7+x = 7+1 = 8 hours after its start, that means at

8×60 = 480 km of its total trip of 600 km.

120 km are still left for the bus to go.

from that point on both travel the same time y going with their speeds until they meet the second time.

the motorcyclist travels 100y km building up distance from B, while the bus travels 60y km reducing the 120 km distance from B.

when they meet the second time, the distance from B for the motorcyclist is the same as the remaining distance for the bus.

so,

100y = 120 - 60y

160y = 120

y = 120/160 = 3/4 = 0.75 hours

so, they meet at

100 × 0.75 = 75 km from B.

Answer:

  Large gear: 2 revolutions, 24 teeth

  Small gear: 3 revolutions, 24 teeth

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.

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.

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

Additional comment

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.

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%.

Answer:

 57/10 or 5 7/10

Step-by-step explanation:

Simplify the following:

3 + 1/5 + 7/2 - 1

Put 3 + 1/5 + 7/2 - 1 over the common denominator 10. 3 + 1/5 + 7/2 - 1 = (10×3)/10 + 2/10 + (5×7)/10 - 10/10:

(10×3)/10 + 2/10 + (5×7)/10 - 10/10

10×3 = 30:

30/10 + 2/10 + (5×7)/10 - 10/10

5×7 = 35:

30/10 + 2/10 + 35/10 - 10/10

30/10 + 2/10 + 35/10 - 10/10 = (30 + 2 + 35 - 10)/10:

Answer:

is the answer of 50 and spend 20 you have 30 left

Answer:

40%

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

theres $20 so thats the 10x2

20 goes into 100, 5 times ...

It just so happens in this scenario, its 20% just like the $20 ... doesnt always happen like this.

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.

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.

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
