boys who brought their lunch today?

Answers

Answer:

the answer is I think 2/3

Fraction of boys brought lunch today is 16/25.

Here,

Given that:

The ratio of boys at certain school = 8/9

And 2/5 of boys brought lunch today

We have to find fraction of boys brought lunch today.

What is fraction?

Fractions denote the parts of a whole or collection of objects.

Now,

The ratio of boys at certain school = 8/9

And 2/5 of boys brought lunch today

Since, the ratio of boys 8/9 denotes 8 boys out of 9 students

Therefore, number of boys = 8

Thus, Fraction of boys brought lunch today = 8 x 2/5

                              = 16/25

If function g is a quadratic function that contains the points (-3,5) and (0,14), which statement is true over the interval [-3,0]?

Answers

Your answer for this question is B

The average rate of change of f(x) is less than average rate of change of g(x). Then the correct option is C.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function f(x) is given in the table, then the rate of change of the function f(x) will be

Rate of change of f(x) = (-2 + 4.5) / (-2 + 3)

Rate of change of f(x) = 2.5

If function g is a quadratic function that contains the points (-3,5) and (0,14).

Then the rate of change of the function g(x) will be

Rate of change of g(x) = (14 - 5) / (0 + 3)

Rate of change of g(x) = 9/3

Rate of change of g(x) = 3

Thus, the average rate of change of f(x) is less than average rate of change of g(x).

Then the correct option is C.

Solve the inequality -5(x - 1) > -40, and graph the solution on a number line.

Answers

Answer:

x<9

Step-by-step explanation:

-5(x-1)>-40

x-1>-40/-5

x-1>8

x>8+1

x>9

x<9

The solution of the inequality - 5(x - 1) > -40 will be;

⇒ x < 9

And, The solution of the inequality is shown in number line.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ - 5(x - 1) > -40

Now,

Solve the inequality as;

The inequality is,

⇒ - 5(x - 1) > -40

⇒ - (5x - 5) > - 40

⇒ 5x - 5 < 40

Add 5 both side,

⇒ 5x - 5 + 5 < 40 + 5

⇒ 5x < 45

Divide by 5, we get;

⇒ x < 9

Thus, The solution of the inequality - 5(x - 1) > -40 will be;

⇒ x < 9

And, The solution of the inequality is shown in number line.
