The distance between the points (3 ,7) and (15 ,16) on a coordinate plane is 15 units.
How to calculate distance between two points in coordinate plane?In coordinate geometry, every point is denoted by definite coordinates since every point is situated at a fixed distance from the origin point (0,0). Any two points on a coordinate space are situated at a constant distance since their coordinates are fixed with respect to the origin. A line segment has two endpoints, and the coordinates of the endpoints help to determine the length of the line segment. Let us suppose (x1,y1) and (x2,y2) are the two points on a coordinate space then the distance between these two points is given by the distance formula as per the below:
[tex]d = \sqrt{(x1 - x2)^2 + (y1 -y2)^2}[/tex]
Calculation:given points are (3 ,7) and (15 ,16).
(x1,y1) = (3,7) and (x2,y2) = (15,16)
We know that two points on a plane have a constant distance in between them, and the distance formula gives the distance between these two points.
d =[tex]\sqrt{(x1 - x2)^2 + (y1 - y2)^2}[/tex]
∴ d = √(3 - 15)^2 + (7 - 16)^2
∴ d = 15 unit.
The distance between the points (3 ,7) and (15 ,16) on a coordinate plane is 15 units.

Emma is taking a trip to the beach. So far, she has driven 58 miles in 1.25 hours.
Determine Emma's constant speed and simplify it to a unit rate.
Then write a linear equation in two variables that represents Emma's distance, d, she travels in any given time t.
Answer:
46.4miles/hour
d=46.4t
Step-by-step explanation:
Let's say d=at, where d = distance, a = the unit rate, and t = any given time.
We're given that Emma takes 1.25 hours to drive 58 miles. Plugging that into our formula of d=at, we get:
58 = 1.25a.
So, a = 46.4.
The formula now becomes d=46.4t.

The vertices of a triangle MNP are M(5,6) , N(0,3) , and P(4,-2). What is the coordinate of the midpoint of the line connecting the midpoints of sides MN and MP
Answer:
(3.5, 3.25)
Step-by-step explanation:
Given the vertices of a triangle MNP as M(5,6) , N(0,3) , and P(4,-2).
Midpoint of MP is expressed as;
M(5,6) and P(4,-2).
Xmp = (5+4)/2
Xmp = 9/2
Xmp = 4.5
Ymp = (6-2)/2
Ymp = 4/2
Ymp = 2
Hence the midpoint of MP is at (4.5, 2)
Similarly for MN
M(5,6) , N(0,3)
Xmn = 5+0/2
Xmn = 5/2
Xmn = 2.5
Ymn = 6+3/2
Ymn = 9/2
Ymn = 4.5
Hence the midpoint of MN is (2.5, 4.5)
The coordinate of the midpoint of the line connecting the midpoints of sides MN and MP will be expressed as;
MN(2.5, 4.5) and MP (4.5, 2)
M = {(2.5+4.5/2, 4.5+2/2)}
M = (7/2, 6.5/2)
M = (3.5, 3.25)
Hence the required midpoint coordinate is (3.5, 3.25)

The Jacksons and the Simpsons were competing in the final leg of the Amazing Race, which was 240240240 kilometers long. In their race to the finish, the Jacksons immediately took off traveling at an average speed of vvv kilometers per hour. The Simpsons' start was delayed by an hour. When they eventually took off, they traveled at an average speed that was 404040 kilometers per hour faster than the Jacksons' speed. Sadly for them, that didn't help, and the Jacksons won. Write an inequality in terms of vvv that models the situation.
Answer:
240/(v+40) + 1 > 240/v
Step-by-step explanation:
Both parties traveled a distance of 240 km.
Simpsons took off at average speed of 40 km/h & 1 hour later: 240/(v+40) + 1
Jacksons took off at average speed of v km/h: 240/v
An inequality in terms of v that models the situation is; [240/(v + 40)] + 1 > 240/v
How to write an inequality?We are told that distance travelled by both Jackson and Simpson is 240 km each.
Jacksons took off at average speed of v km/h. Thus, their time taken is 240/v
The Simpsons took off at an average speed of 40 km/h faster than Jacksons Speed. Since their start was delayed by an hour, then;
Time taken = [240/(v + 40)] + 1
Thus, the inequality that models the situation is; [240/(v + 40)] + 1> 240/v

Mr. Frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 93 mg of fertilizer 4 times each year. What is the number of plants he could fertilize with that amount? How much fertilizer will he have left over?
Answer: See explanation
Step-by-step explanation:
First and foremost, we should know that: 1 kilogram = 1,000,000 milligrams
Therefore, 1.08kg will be converted to milligram and this will be:
= 1.08 × 1,000,000 milligrams
= 1,080,000 milligrams
Since every plant gets 93mg of fertilizer, the number of plants that can be fertilized will be:
= 1,080,000 / 93
= 11612.903
Therefore, 11612 plants can be fertilized.
The fertilizer left over will be:
= 1,080,000 - (11612 × 93)
= 1080000mg - 1079916mg
= 84 mg

Let length = x
Let width = y
Area = xy
Perimeter equation is
2(x + y) = 356
x + y = 178
Substituting the perimeter equation in the area formula,
Area = x(178 - x)
Area = -x2 + 178x
If the zeros of this quadratic are 0 and 178, then the median is where the maximum area occurs.
178 / 2 = 89
Therefore, the dimensions are
length = 89 feet
width = 178 - 89 = 89 feet
Maximize the enclosed area of the rectangle is 85 ft by 85 ft.
What is perimeter of rectangle?Perimeter of rectangle is defined as addition the lengths of the rectangle's four sides.
Let length = a
Let width = b
Area of rectangle = ab
Perimeter of rectangle equation is 2(a + b)
2(a + b) = 340
a + b = 170
Substitute the perimeter equation in the area formula,
Area = a(170 - a)
Area = -a² + 170a
If the zeros of this quadratic are 0 and 170, then the median is where the maximum area occurs.
170 / 2 = 85
Therefore, the dimensions are
length = 85 feet
width = 170 - 85 = 85 feet
The rectangle is a square.

To solve this problem we can use the Pythagorean theorem. In fact the diagonal of a rectangle is an hypotenuse of a right triangle, while the length is a leg. The width is the other leg
width = √2^2 - (√3)^2 = √4 - 3 = √1 = 1 cm
A camping store is having a summer sale. Stoves are being sold at 40% off. If the sale price is $57 what was the original price of the stove before the sale
Answer:
The original price was $142.5.
Step-by-step explanation:
40 ÷ 100 = 0.4
$57 ÷ 0.4 = $142.5
Therefore, $142.5 is our answer.
Answer:
142.5
Step-by-step explanation:
Let's say the original price of the store before the sale is x
so 40% x X = $57
40/100 (X ) =57
0.4 (X) = 57 ====> X = 57 / 0.4 = 142.5
The original price of the stove before the sale is $ 142.5

write an equation of the line that passes through 3,1 and 0,10
Answer:y = -3x + 10
Step-by-step explanation:
To find an equation of a line that passes through two points, we have to first find the slope between the two equation. We can do this by using the slope formula:
where (x₁, y₁) and (x₂, y₂) are the two points that we are finding the slope between.
Lets make (x₁, y₁) equal to (0, 10) and (x₂, y₂) equal to (3, 1). Now we plug them into the slope formula:
So the slope between the two points is -3.
From here, I would normally take one of the points given to us and plug in the point and slope into the point-slope form of a line and then simplify until we get it in slope-intercept form. But if you look carefully, the y-intercept is given to us as the point (0, 10). So we now know that the y-intercept of the line is 10. We can now take the y-intercept and the slope and plug it into the slope-intercept form of a line to get out equation:
y = mx + b
plug in -3 for m (the slope) and 10 for b (the y-intercept)
y = -3x + 10
So now we have our equation.
I hope you find my answer and explanation helpful. Happy studying. :)
