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
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

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.

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.

In Britain a Value Added Tax (VAT) of 17% is added to most purchases. If a skit costs $58.50 including tax, what is the price of the skirt before tax?
Answers
Answer:
i think it is 45.70
Step-by-step explanation:
Answer:
$48.55
Step-by-step explanation:
Make 17% into a decimal Multiply 0.17 and the number of Britain Value including tax Then take that number and subtract it by the number of Britain Value including taxEquation:
17% = 0.17
Why? The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.
0.17 × (Britain Value Including Tax) 58.50 = 9.945 to be exact but I rounded it up to 9.95 for easier use
58.50 - 9.95 = 48.55
So $48.55 is your answer

7th grade math <3 pls help heh
Answers
Answer:
a. 12a + 3b
b. 5b + 3a
Step-by-step explanation:
Which terms have the same thing applied to them? This is what I ask myself while figuring these out.
a. 5 and 7 both are multiplied by a, so you can combine the expressions to make 12a.
b. 10b - 5b = (10 - 5)b
Both 10 and 5 are multiplied by b, so you can just subtract the integers to get 5b.
I hope this helped!
B. Just like in the last problem. You would do 10-5 because they both have b. So it would be 5b+3a
Fernando spent $20 of his $50 weekly allowance on snacks. What percent of his weekly allowance did he spend snacks?
Answers
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.
