When either their ratio or product results in a constant, two variables' values are said to be proportionally related. The ratio between the two specified quantities determines the value of the proportionality constant.So, (A) To make the same shade of green:
Cups of blue paint: 2Cups of yellow paint: 10Then, cups of yellow paint when blue paint is just 1 cup:
10/2 = 5/1 = 5
Therefore, 5 cups of yellow paint will be needed with 1 cup of blue paint to make the same green shade.
(B) New pair of numbers to make the same green shade:
Old pair:
Cups of blue paint: 2Cups of yellow paint: 10Another pair:
Cups of blue paint: 1Cups of yellow paint: 5The new pair would be:
Cups of blue paint: 2 × 2 = 4Cups of yellow paint: 10 × 2 = 20Therefore, the new pair to make the same shade of green will be 4 cups of blue paint and 20 cups of yellow paint.
(C) Proportional relationship:
Let cups of blue paint be: xCups of yellow paint be: yOld pair:
Cups of blue paint: 2Cups of yellow paint: 10Proportional relationship will be:
2x/10y = x/5y ⇒ x : 5yTherefore, the proportional relationship of the table will be x : 5y.

John's commute to work is 20kmhr while Sheri's commute is 500mmin.
Who has the fastest commute to work in mihrif 1.61km=1mi?
Answers
By 6.2 miles per hour, Sheri commutes more quickly.
We are given that,
John travels to work = 20km/hr
Sheri travels to work = 500m/min converting this into km/hr we get ,
1.61km/hr or 1 mile
John travels to work at the following rate:
[tex]\frac{20 km}{1 hr} * \frac{1 mile}{1.61km} = 12.42 miles/hr[/tex]
Sheri travels work at the following rate:
[tex]\frac{500m}{1min} *\frac{1km}{1000 m}*\frac{1mile}{1.61km}*\frac{60min}{1hr}=18.63 miles/hr[/tex]
Computing the difference between the two,
18.63 miles/hr - 12.42 miles/hr = 6.21 miles/ hr ≈ 6.2 miles/ hr
thus, by 6.2 miles per hour, Sheri commutes more quickly.

In reality, you’re using the midpoint formula. The midpoint formula is as follows:
(x1+x2)/2 , (y1+y2)/2
For example,
If you had point (2,4) and (4,8) you would plug in the equation as follows.
(2,4) = x1,y1
(4,8) = x2,y2
(2+4)/2 , (4+8)/2

the ratio of action movies to all movies is 2: 5 .
In mathematics, a ratio illustrates how frequently one number appears in another. On a fruit tray, the ratio would be eight to six if there were eight oranges and six lemons.
Ratios can be lowered by dividing each quantity by the sum of all the common factors between the numbers (much like fractions are).When the ratio's numbers are the smallest practical integers, the fraction is said to be in its simplest form.The ratio's antecedent and consequent are frequently referred to as A and B, respectively.Let Brayden has x number of movies in total.
Total number of action movies in his collection = 40% of x = 0.4 x
Other movies = 1 - 0.4x = 0.6 x
Ratio of action movies to all movies = 0.4x : x = 2: 5

What is the unitary method of problem solving?
A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. In the unitary method, the value of a unit quantity is determined before the values of other units are determined. Direct variation and inverse variation are its two different forms of variations. When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other. If we increase one quantity in inverse variation, the value of another quantity will drop.
Given, time taken by robot to complete five tasks = 0.75 hours
Thus, time taken by robot to complete one task = (0.75/5) = 0.15 hours

Approximate the length of the pole. Round to the nearest hundredth.

The length of the pole is 19.15 feet.
What is the angle of elevation?The angle of elevation is the angle created when an observer looks at an object placed above its height in relation to the eye level or the horizontal line. An angle of elevation is, for example, the angle created between the line of sight and the horizontal line when a man on Earth observes the Sun.
Given:
Angle made by straight road = 15°
Angle of elevation of the sun = 57°
Length of the shadow = 75 feet
∠ACB = 90° - 57° = 33°
∠CAB = 57° - 15° = 42°
Using Sine Law to find BC i.e.length of the pole.

all the students in an algebra class took a 100-point test. five students scored 100, each student scored at least 60, and the mean score was 76. what is the smallest possible number of students in the class?
Answers
The smallest possible number of students in the algebra class is 13.
What is meant by the word inequality?Inequalities define the connection between two non-equal values. Inequality means being unequal. If two values really aren't equal, we use the "not equal symbol (≠)".Let n≥5 be the number of students.
The sum of their scores must be at least 5×100 + (n - 5).
Simultaneously, we must achieve the mean 76, which is equivalent to achieving the mean sum 76n.
As a result, we have a sufficient precondition on n: we should have 5×100 + (n - 5) ≤ 76n.
This can be reduced to 200 ≤ 16n. This is true for the smallest integer n = 13.
To complete our solution, we must now determine how 13 students might have scored just on test.
We have 13×76 = 988 points to distribute to them. Because five 100s equal 500, we must distribute the remaining 488 points as among remaining eight students.
This can be accomplished, for example, by awarding each of them 61 points.
Thus, the smallest possible number of students in the class is 13.

c) The x-intercepts of y=f(-1/2x) is (-1/8,0) (1/6,0)
d) The x-intercepts of y=f(-(x+1)) is (-5,0) (2,0)
What is x-intercept?A line's x-intercept is the distance in x coordinates from the line's intersection with the x-axis at its origin. A location on the graph where y is 0 is known as the x-intercept. The x-intercept of a line that is perpendicular to the y-axis is undefined.
Here to determine the x-intercept put y=0,
Given f(x)=(x-4) (x+3)
a) y=(x-4) (x+3)
Replacing y by 0 we get,
(x-4) (x+3) =0
x=-3, 4
Therefore, x-intercepts of y=f(x) is (-3,0) (4,0)
b) y = -2(x-4) (x+3)
Replacing y by 0 we get,
-2(x-4) (x+3) =0
x=-3, 4
Therefore, x-intercepts of y=-2f(x) is (-3,0) (4,0)
c) y= (-[tex]\frac{1}{2x}[/tex]-4) (-[tex]\frac{1}{2x}[/tex]+3)

Therefore, x-intercepts of y=f(-1/2x) is (-1/8,0) (1/6,0)
d) y=(-(x+1)-4) (-(x+1) +3)
Replacing y by 0 we get,
(-(x+1)-4) (-(x+1) +3) =0
By solving the above equation
(-(x+1)-4) =0 and (-(x+1) +3) =0
-(x+1) =4 and -(x+1) =-3
x=-5, 2
Therefore, x-intercepts of y=f(-(x+1)) is (-5,0) (2,0)

How to understand the concept of mensuration?The word "mensuration" literally means "to measure." It is typically employed when dealing with geometric shapes when it is necessary to calculate different physical values like perimeter, area, volume, or length. Mensuration is the term for measuring these amounts.
According to the given data:So with respect to the information provided to us :
Height of a cone =3* radius of the base
let height be h and radius be r
h=3r
The Formula for volume of cone is:
V=1/3hπr²
Putting the value we get:
343=1/3*π*r²*3r:
r= √343/π
Therefore ,
the volume of the cone whose height is three times its radius is:
√343/π
