Answer:

8/9

Step-by-step explanation:

4/5 ÷ 9/10

4/5 x 10/9

40/45 or 8/9

A division is a process of splitting a specific amount into equal parts.8/9 is the quotient for 4/5 ÷ 9/10.

a division is a process of splitting a specific amount into equal parts.

While doing division process we have some important parts of division which are dividend, divisor, remainder and Quotient.

In the given problem 4/5 is he divisor and 9/10 is the divisor.

Four by five divided by nine by ten

4/5 ÷ 9/10

When two fractions are divided, the division turn to multiplication when the denominator fraction shifts to up.

4/5 x 10/9

Cross over the fraction with 5.

40/45

8/9

Hence 8/9 is the quotient for 4/5 ÷ 9/10.

Answer:

Choc Bar: 258 cals

Coco Bar: 264 cals

Step-by-step explanation:

What we can do here is something called making a system of equations.

Let us name the choc. bars x and the coco. bars y.

Then, we can get:

x+2y=780

2x+y=786

Next, we solve for x in the first equation

x=780-2y

Now, we can substitute:

2(780-2y)+y=786

1560-3y=786

-3y=-774

y=258

x=780-516

x=264

The proportional equation representing the area Felicia covered, y, in terms of the number of tiles she used, x is:

[tex]y = \frac{x}{6}[/tex].

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

Researching this problem on the internet, we have that 6 tiles cover 1 square feet, 12 tiles cover 2 square feet, and so on, hence the constant is given as follows:

[tex]k = \frac{1}{6} = \frac{2}{12}[/tex]

Hence the function is given as follows:

[tex]y = \frac{x}{6}[/tex].

Answer:

The range of F(x) = logo x is the set of all real numbers is True.

Step-by-step explanation:

Yes, Because range of the logarithmic function is the set of ''all real numbers.'

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

The function is,

⇒ f (x) = log x

Now,

The given function is a logarithmic function.

And, The range of the logarithmic function is the set of all real numbers.

Hence, The range of function F(x) = log x is the set of all real numbers.

Thus, The range of F(x) = log x is the set of ''all real numbers''.

Answer: a2 + b2 = 202

Step-by-step explanation: Since they are consecutive odd integers, then we can just divide 202 by 2, square root it, then round to the nearest two odd integers. In this case, 202 / 2 = 101 ⇒ 1010.5 ≈ 10.04. The two nearest odd integers are 9 and 11. We can verify that this is the pair: 92 + 112 = 81 + 121 = 202.
