Fraction - The distance she walked before lunch 214 / 75 miles
What is Fraction ?
A fraction, which also represents a portion of a whole, is a mathematical symbol for any number of equal parts. A fraction, such as one-half, eight-fifths, and three-quarters, indicates the number of components of a specific size when used in conversational English.
Given that,
The distance Ruby has to walk = 10/3miles
The distance left to complete before stopping = 12/25miles
The distance Ruby has to walk before lunch = 10/3 - 12/25
= 250 - 36 / 75
= 214 / 75miles
Hence, she walked 214 / 75 miles before lunch

hey math genius can anyone help me out with these questions.. I will mark you brainlist if your answer is correct..
please:):):)
a) Because it is an equilateral triangle, all the sides must have equal lengths.
The perimeter = 24cm -> Each side = 8.
Area = 1/2 b.h = 8.8.1/2 = 32 cm2.
b) A square has all of its sides of equal lengths just like an equilateral triangle.
The perimeter = 24cm -> Each side = 6.
Area = side.side = 6.6 = 36 cm2.
c) Since they have equal perimeters and the same properties (all sides equal) BUT they have different number of sides and lengths, they won't have the same areas.
d) A rectangle. E.g :
A set of lengths of 5cm and 7cm makes a rectangle with a perimeter of 24cm : (5+7).2
But, its area equals 5 x 7 = 35cm2, which is greater than the triangle.
Answer:
a) 27.71 cm²
b) 36 cm²
Step-by-step explanation:
a) Perimeter of equilateral triangle = 3a
Here, a is the side of equilateral triangle.
Perimeter of equilateral triangle = 24 cm
3a = 24 cm
a = 24 ÷ 3
a = 8 cm
[tex]\sf Area \ of \ equilateral \ traingle = \dfrac{\sqrt{3}}{4}a^2[/tex]
[tex]\sf = \dfrac{\sqrt{3}}{4}*8*8\\\\ = 1.732*2*8\\\\ = 27.71 \ cm^2[/tex]
b) Perimeter of square = 4s
Here, s is the side of square.
Perimeter of square = 24 cm
4s = 24
s = 24 ÷ 4
s = 6 cm
Area of square = s*s
= 6 * 6
= 36 cm²
c) When the dimensions (length, width, height) of the shape changes, the area and volume changes.
d) Length of the rectangle is 10 cm and width is 2 cm.
Perimeter of rectangle = 2*length + 2* width
= 2*10 + 2*2
= 20 + 4
= 24 cm
Area of perimeter of rectangle = length *width
= 10 * 2
= 20 cm²

into details about why it is 1/2 (ill call 2-x as y for easier demonstration)
9^y = 3
(3^2)^y = 3

1. The slope of the line on the graph is: 6
2. The graph of the line with a slope of 4/3 is shown in the image below.
What is the Slope of a Line?Slope of a line = change in y / change in x = rise/run.
How to Graph an Equation?The equation that can be used to represent a linear graph can be written in slope-intercept form as y = mx + b, where the value of b is the y-intercept of the line and the value of m is the slope of the line.
1. Using two points on the line, (0, -1) and (1, 5):
Slope of the line = change in y / change in x = (-1 - 5)/(0 - 1)
Slope of the line = -6/-1
Slope of the line = 6
2. Slope (m) = 4/3
A point on the line is given as (1, 3)
Write the equation of the line by substituting (a, b) = (1, 3) and m = 4/3 into y - b = m(x - a):
y - 3 = 4/3(x - 1)
y - 3 = 4/3x - 4/3

The required equation of slope intercept the line parallel to the given line and passing through (4,5) is y = -1/4x + 6.
What exactly does slope intercept mean?
A method of expressing a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line is drawn the y-axis is known as the y-intercept, and the slope refers to how steep the line is.
1) 5x + y = 3
y = - 5x + 3
compare equation y = mx + c
m = -5
2) 7x - 5y = 20
5y = 7x - 20
y = 7/5x - 4
compare equation y = mx + c
m = 7/5
3) y = -1/3x - 4
compare equation y = mx + c
m = -1/3
4) points ( 4,5) parallel to y = 1/4x - 4
m₁ = m₂
compare equation y = mx + c
m₁ = 1/4 c = -4
now lets put the value
1/4 = m₂
So the equation of the line parallel to the given line assuming that its y-intercept is b will be
y = 1/4x + b
the equation of the parallel line which passes through
(4,5, it should satisfy these points.
So let's substitute these points
5 = -4/4 + b
5 = -1 + b
b = 6
Hence the required equation of the line parallel to the given line and passing through (4,5) is
y = -1/4x + 6

A force of 85 N is applied over an area of 530 cm2. Then the pressure on it is equal to 1603.8 [tex]\frac{N}{m^{2} }[/tex].
Force(F) = 85 N
