What is percentage?A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given:
The weights (in pounds) of seven people:
100, 115, 135, 140, 180, 197, 230.
We have to find the 80th percentile first we have to find the mean of seven people.
Mean=100+ 115+135+140+ 180+197+ 230/7
Mean=156.71
100 percent=156.71
80 percent=156.71*80/100
80 percent=125.37.
Therefore, the 80th percentile is 125.37.

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

The diagram shows five touching semicircles, each with radius 2. What is the length of the perimeter of the shaded shape? Give your answer in terms of π
The Length of perimeter of the shaded shape is; 24 - 8π
What is the Perimeter of the shaded area?
Let us first find the rectangle measurements that contains the shaded portions.
Width of rectangle = 2 * 4 = 8
Length of rectangle = 2 + 2 = 4
Perimeter of rectangle = 2(8 + 4) = 24 units
Now, let us find the perimeter of all semi circles and quarter circles that fall into into this rectangle region;
Perimeter of semi circles = πr + πr + πr + πr/2 + πr/2 = 4πr
Perimeter of semi circles inside the rectangle = 4π * 2 = 8π
Thus;

Three numbers are in the ratio 2:5:7 and their lcm is 490 find the square root of the largest number
Answer:
49
Step-by-step explanation:
The ratio of three numbers = 2:5:7
Then the numbers are 2x,5x and 7x
Given that the LCM of these numbers = 490
LCM of 2x,5x,7x is 2×5×7×x = 70x
Then, we have 70x = 490
x = 7
Hence, the numbers are 14, 35 and 49
Largest number = 49

The cross-section of a lean-to shelter is in the shape of a triangle. The base of the
triangle is 10 feet more than twice its height. If the area of the triangle is 126
square feet, determine the length of the base and the height of the triangle in feet.
foot
The length of both the triangle's base and height in feet.
length of base = 32ft
height = 14 ft.
The triangle's base and height:The base of a triangle can be any of its sides. The term "base" refers to the both the side and the length (the measurement). The comparable height is really the length of a perpendicular segment from either the base to the opposing vertex.
According to the given data:Given that perhaps the cross-section of the lean-to shelter is a triangle, its area is a triangle.
A = ¹/₂bh
b = length of base
h = height
the base of the triangle is 10 feet more than twice its height, we have that
b = 2h + 10
A = ¹/₂bh
A = ¹/₂(2h + 10)h
A = h² + 5h
Since the area of the triangle is A = 126 ft², we have that;
h² + 5h = 126
h² + 5h - 126 = 0
h² +(14h -9h) - 126 = 0
h² +14h -9h - 126 = 0
h(h + 14) -9(h + 14) = 0
(h + 14)(h - 9) = 0
Hight cant be negative:
h = 14
Length of the base is b = 2h + 10
b = 2h + 10
b = 2(14) + 10
b = 28 + 10

Answer:
f(p) = 18p + 40
Step-by-step explanation:
Since they can make 18 pizzas per hour, number of pizzas made in p hours = 18p
They already have 40 pizzas
So total number of pizzas at any time p is f(p) = 18p + 40
If a person drives 360 miles at an average of 35 miles per hour, then their distance d from the destination (in miles) is a function of the number of hours h driven.
The required function is d = 360 - 35h, 0 ≤ h ≤ 10.29.
We know that distance travelled is equalled to speed multiplied by time.
Let d be the distance from the destination.
Let d₁ be the distance travelled in h hour.
And h be the number of hours driven.
Given that the average speed is 35 miles per hour.
Therefore, we have d₁ = 35h
And the initial distance from the destination is 360 miles.
Note at time h= 0 the distance from the destination is the maximum which is 360 miles.
Therefore, we have d₁ = 35h
Distance from the destination is 360 - d₁.
⇒ d = 360 - d₁
⇒ d = 360 - 35h
Time taken to reach destination = d/v = 360/35 = 10.29 hours
Therefore the required function is d = 360 - 35h, 0 ≤ h ≤ 10.29

The ability to compare settlement intensities across geographical areas is made possible by population density. The number of persons per square mile of land area is the most common way to express population density in the United States.The given parameters are
Number of people = 21400 residents
Area = 1 mi²
Convert the square mile to square kilometer
1 x 1.609² = 2.588881 Km²
Population density = Number of residents ÷ area
Population density = 21400 ÷ 2.588881
Population density = 8266.12 per square kilometer

solve 4p-7r=pq+16 for p
Answer:
p = (7r+16) / (4-q)
Step-by-step explanation:
4p - 7r = pq + 16
Add 7r to both sides.
4p = pq + 16 + 7r
Subtract pq from both sides.
4p - pq = 7r + 16
Factor out p from the left side.
p(4 - q) = 7r + 16
Divide both sides by (4 - q).
p = (7r + 16)/(4 - q)
The 7r and the 16 could be in either order, like 7r+16 or 16+7r. You could show that the answer is a fraction with 7r+16 on top and 4-q on the bottom. If you are writing or on the computer selecting a fraction that is stacked you don't need need the parenthesis.
