Step-by-step explanation:

sorry if I did it wrong

Answer:

D or the last option

Step-by-step explanation:

38/6, so 6 can go on 38 6 times, means it will be 6 times 6, which is 36. So, we can eliminate the answers A and B.

38-36 = 2, which is the left over. Now You add a decimal point and bring down a zero and make it 20. and 6 can go on 20, 3 times... 6 times 3, which is 18.

20-18= 2, so you do the same thing over and over again, the answer is 6.3

The constant of variation is 1/3 and when x = 3/4, y = 1/4

Two variables are proportional to each other if as one variable increase or decrease, the other variable does the same.

Given that y and x have a constant variation, hence:

y ∝ x

y = kx;

where k is the constant of variation

y=2 when x=6;

2 = 6k

k = 1/3

y = (1/3)x

When x = 3/4;

y = (1/3)(3/4)

y = 1/4

Hence the constant of variation is 1/3 and when x = 3/4, y = 1/4

Roberto did not include the first term of the numerator (0-2)^2 in his calculation.

The mean of the data is also known as average.

Given the set of data 0, 2, 1, 2, 5

Mean = 0+2+1+2+5/5

Mean = 10/5

Mean = 2.0

To get the standard deviation, we will use the SD formula as shown:

[tex]\sigma=\sqrt{\frac{\sum (x-\overline x)^2}{N} }[/tex]

[tex]\sigma =\sqrt{ \frac{(0-2)^2+(2-2)^2+(1-2)^2+(2-2)^2+(5-2)^2}{5}}\\ \sigma = \sqrt{\frac{4+0+1+0+9}{5}} \\\sigma = \sqrt{\frac{14}{5} }\\\sigma = 1.673[/tex]

Comparing this with Roberto's calculation, we can see that Roberto did not include the first term of the numerator (0-2)^2 in his calculation.

The function for the amount of money earned, the total amount of money for 40 hours and the expression for the difference quotient are given as A(x) = 5x³ - 20x, 319200 and 15x² - 15xh - 20 respectively.

A function y = f(x) is defined as a one to one relation between sets X and Y. The set X is called the domain while Y is called the range of f(x).

The given function for earned money in designing house is,

f(x) = 25x² - 100

The function for number of rooms decorated is,

g(x) = x/5

PART A :

As per the problem, the the function for the amount of money made by interior designer is the product of functions f(x) and g(x) as,

A(x) = f(x)g(x)

=> A(x) = (x/5)( 25x² - 100)

=> A(x) = 5x³ - 20x

Where x represents the number of hours worked.

PART B :

If the designer works for 40 hours the amount of money earned can be obtained by substituting x = 40 in A(x) as follows,

A(x) = 5x³ - 20x

at x = 5

A(5) = 5 × 40³ - 20 × 40

       = 319200

PART C :

The difference quotient for the function A(x) is given as,

(A(x + h) - A(x))/h

= (5(x + h)³ - 20(x + h) - (5x³ - 20x))/h

= (15x²h - 15xh² - 20h)/h

=  15x² - 15xh - 20

Hence, the answers for all the parts are A(x) = 5x³ - 20x, 319200 and 15x² - 15xh - 20 respectively.

Step-by-step explanation:

Multiply the numerator by the reciprocal of the denominator.

251

300

= 56

Any number can be converted to fraction if you use one for the denominator:

84/1

Therefore now that we've converted 84 into the fraction, to work out the lowest term, we put the fraction 2/3 side by side with our new fraction, 84/1 so that we should multiply those 2 fractions.

all you need to do is convert the whole number into the fraction or then multiply the numerators or denominators :

2 x 84 / 3 x 1

= 168 / 3

In this situation, our new fraction shall actually be the simplified down further. To do that, we want to find the greatest common factor of those numbers.

We can now sum both the new numerator or the denominator by the three to simplify this fraction down to its lowest terms.

168/3 = 56

3/3 = 1

When we put that together, we could see that our complete solution is:

56/1

= 56

Answer:

With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Since height is commonly measured in centimeters, an alternate calculation formula, dividing the weight in kilograms by the height in centimeters squared, and then multiplying the result by 10,000, can be used.

An algorithm is the series of steps followed to do calculations especially by a computer.

[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{2}{12}[/tex]  =[tex]\frac{1}{6}[/tex]

The algorithm would use the multiplication of the numerator with the numerator and the denominator with the denominator for solving simple multiplication of the proper fractions.

[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{3}[/tex]

= (1×2)/(4×3)  ⇒ the numerators are multiplied and so the denominators

= 2/12

Now 2 is taken as common from both 2 and 12 ( numerator and denominator)

= (2/2 ) 1/6   taking 2 as common factor

= 1/6         cancelling 2 by 2

The diagram can be used to explain the same fact.

1 is multiplied with 2 and 4 is multiplied with 3.

Therefore we get 2 as numerator and 12 as denominator.

2/12 is further reduced to 1/6

We want to study the angle of an arc given that the length of the said arc is smaller than the radius of the circle.

The correct option is:

"it is less than pi radians"

A circle of radius R has a circumference:

C = 2*pi*R

An arc defined by an angle θ has a length:

L = θ*R

Now, we know that the length of the arc is smaller than the radius, then we have:

θ*R < R

Dividing both sides by R we get:

θ < 1

So we can see that the correct option is:

"it is less than pi radians"

Because it is smaller than 1.
