The amount of string that can be stretched by 3 kg weight is 5/ 4× 3

= 15 / 4 = 3.75 cm

Given ; The string is attached to a weigh whose weight is 8 kg

the length of the string which is being stretched is 10 cm

The amount of string that can be stretched by 3 kg weight can be calculated by unitary method

According to the unitary method ;

the string when attached to a 1 kg weight the length will be = 10 / 8 = 5 /4

Thus the amount of string that can be stretched by 3 kg weight is 5/ 4× 3

= 15 / 4 = 3.75 cm

Step-by-step explanation:

If linear function can be modeled using the equation 2x-y=2. Then x=1 is the Zero of this function

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

2x-y=2

We need to write this in slope intercept form

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

y=2x-2

m=2 and y intercept is -2

Now take the values of x and y

x       0       1         2         3

y       -2      0         2         4

Hence the zero of this function is x=1

Will assume that there are 100 kids.

100 x 40% =40 of them are boys

40 x 70% =  28 boys arrive by car.

100 - 40 = 60 - Number of girls in Nursery.

60 x 60% = 36 of them arrive by car.

28 boys + 36 girls = 64 - kids that arrive by car.

64 / 100 = 64% - probability of a randomly picked kid that he/she arrived by car.

He can buy 5 candy at most with this inequality 2c-3<9 as the inequality will result in c<6 as the definition of inequality says, "In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another".

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another. The equation-like form of the expression 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. This shows that the left part, 5x 4, is bigger than the right part, 2x + 3. The greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), and not equal to symbol () are the five inequality symbols. Take the same amount away from both sides. Add the same positive number to both sides. Subtract the same positive number from both sides. Reverse the sign and multiply both sides by the same negative number.

Here,

2c-3<9

add 3 both side,

2c-3+3<9+3

The answer will be [tex]4^{30}[/tex]  different ways can the question be answered using permutation.

What is permutation?

A permutation is both an ordered combination and an ordered arrangement of results. For instance, 3 people are to sit in each of the 5 chairs. The first person can be seated in five different ways, the second person in four different ways, and the third person in three different ways. Accordingly, generalising this, we obtain n alternatives to fill the first chair, n-1 options to fill the second, and n-2 options to fill the third chair. As a result, nPr = n! / (n - r)! can be used to represent how many different permutations (arrangements) there are when there are r individuals and n chairs.

Each question has four choices. So, the total number of ways in which the questions can be attempted is [tex]4^{30}[/tex]

Hence the number of ways the question be answered is  [tex]4^{30}[/tex].

Answer:

a) 18 and b)1:2

Step-by-step explanation:

for a i divided 24 by 4 (24:4) and got 6 the i multiplied 3 by 6 and got 18. also you could do a proportion and fruit scones would be x so you have to calculate x. if you don't know how to do proportions you can ask me i can explain.

for b since i got the count was 18:24. i took away those six from 18 and got with the ratio 12:24. i divided both sides by twelve and got 1:2

Answer:

a) 18 fruit scones

b) 6:8

Step-by-step explanation:

a) The ratio is 3:4 given that there 3 fruit scones to 4 cheese scones so if there are 24 cheese scones, 24/4=6, 3*6=18 so there 18 fruit scones.

b)  The ratio is 3:4 given that there 3 fruit scones to 4 cheese scones so if there are 6 fruit scones, 6/3=2, 2*4=8 so there are 8 cheese scones. The new ratio would be 6:8

The equation represent the given situation is y=3x+10.

What is equation?

   A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here let us take the values of time and amount as x and y. Then take any two points ,

[tex](x_1,y_1)=(3,19)\\(x_2,y_2)=(6,28)[/tex]

Now using slope formula,

=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> slope m = 9/3 = 3

Now using equation formula ,

=> [tex]y-y_1=m(x-x_1)[/tex]

A quadratic function has the generic form f(x)=ax²+bx+c. A parabola, a kind of two-dimensional curve, is the graph of a quadratic function. A polynomial function of degree two in one or more variables is known in algebra as a quadratic function, quadratic polynomial, polynomial of degree 2, or simply a quadratic. The phrase "quadratic" in mathematics refers to something that has to do with squares, the squaring operation, terms of the second degree, or equations or formulas that contain such terms. Latin's word for square is quadratus.

Function:

2x² + 4x + 7 = 0

ax² + bx + c = 0

x = [tex]\frac{-b +-\sqrt{}b^{2}- 4ac }{2a}[/tex]

a = 2

b = 4

c = 7

Using quadratic function,

x = [tex]\frac{-4\sqrt{} 4^{2} -4(2)(7)}{2(2)}[/tex]

x = [tex]\frac{-4+-\sqrt{-40} }{4}[/tex]

So,

i = √-1

x = [tex]\frac{-4+-2i\sqrt{10} }{4}[/tex]
