area of composite figures worksheet #1 (don’t mind the pen it’s a mistake)

Answer:107/56 is the answer

hmmm first of all, let's keep in mind that any expression multiplied by 1 is always the same expression

[tex]12\cdot 1=12\qquad 13567\cdot 1=13567\qquad spaghetti\cdot 1=spaghetti[/tex]

and so on.

now, hmm 1 can be expressed as a rational, 1/1 = 1, but but but, we can really express it as

[tex]\cfrac{9999}{9999}\implies \cfrac{7857}{7357}\implies \cfrac{\sqrt[11]{1375}}{\sqrt[11]{1375}}\implies \cfrac{spaghetti}{spaghetti}\implies \cfrac{lettuce}{lettuce}\implies \text{\Huge 1}[/tex]

so let's do the so-called rationalizing of the denominator, we can also do it with the numerator btw, but we only need it for the denominator right now, by multiplying for 1 :), 1 is Da Bomb baby!!

[tex]\cfrac{5}{2\sqrt{5}}\cdot \text{\LARGE 1}\implies \cfrac{5}{2\sqrt{5}}\cdot \cfrac{\sqrt{5}}{\sqrt{5}}\implies \cfrac{5\sqrt{5}}{2\sqrt{5^2}}\implies \cfrac{5\sqrt{5}}{2(5)}\implies \cfrac{5\sqrt{5}}{10}\implies {\Large \begin{array}{llll} \cfrac{\sqrt{5}}{2} \end{array}}[/tex]

Answer:

you have the values of a, b and c

all you gotta do is just plug them in so

ab+bc is (3)(6)+(6)(5)

which equals 48.

Answer:

48

Step-by-step explanation:

since a=3, b=6 and c=5, you would replace the letters in ab+bc with their numbers, making it (3)(6)+(6)(5). then you would multiply 3 x 6 which would be 18, and 6 x 5, which would be 30, making your expression 18+30. finally you would add them together, making it 48.

The revenue of the the agency is given by the function

R(x) = 5000 - 50 x - 3x² .

A function is a relationship between an independent variable and a dependent variable which defines all points on a cartesian plane which satisfies the given condition.

Now in the given Agency it is given that the charge of each tourist is $100 . Now for every tourist above 50 the charge is reduced by 3 dollars.

So for x people above 50 charge will be ( 100-3 x ) for all members.

The total revenue can be measured by the function

R(x) = ( 50 + x ) ( 100 - 3x )

or , R(x) = 5000 - 150 x + 100 x - 3x²

or, R(x) = 5000 - 50 x - 3x²

Hence the revenue function is given as : R(x) = 5000 - 50 x - 3x²

Reason:

The smallest |x-5| can get is 0 since the result of an absolute value is never negative (because it represents distance).

So the smallest f(x) = |x-5|-3 can get is 0-3 = -3

f(x) = -3 or f(x) > -3 are the only two options for the output f(x).

Condense that into [tex]f(\text{x}) \ge -3[/tex] to arrive at choice C as the final answer.

John holds 26 percent of the debt from discover bank in its total debt obligation.

The Total debt represents the obligations being taken by a company in the form of debt and yet to be repaid by them to the lender.

Given that the Debt hold in discover bank is $10,000

Total debt: $26,000

Computation of ratio of debt in discover bank:

Debt proportion = Debt hold in discover bank / Total debt

Debt proportion = 10,000/ 26,000

Debt proportion = 26%

Therefore, John holds 26 percent of the debt from discover bank in its total debt obligation.

Answer:

side length = 5cm

Step-by-step explanation:

The volume of the prism is:

V = l × w × h

But we only know the width and height which are both 3cm. See image.

We put it in the calibrated container (container with markings on it) We find out the volume is 45. Because 115 - 70 is 45.

Divide to find the missing length. See image.

Vol

= 3 × 3 × sidelength

V = 9s

45 = 9s

5 = s

An ordered pair of point in Quadrant II is 8 units away from this point, the resulting point will be (-7.25, 4.25)

In this question, we need to find an ordered pair for the point in Quadrant II, that is 8 units away from the point Q(0.75 -3.25) on a coordinate plane.

If we have a coordinate point (x, y) in Quadrant ||, if the coordinate is 8 units away, the resulting coordinate will be expressed as (x - 8, y + 8)

Given the point Q(0.75, -3.25) on the coordinate  the plane, if a point in  Quadrant II is 8 units away from this point, the resulting point will be (0.75 - 8, -3.25 + 8) which is (-7.25, 4.25)

Therefore, an ordered pair a point in Quadrant II is 8 units away from this point, the resulting point will be (-7.25, 4.25)

Capacity of 1 thumb drives = 4 gigabytes.

Capacity of 1 compact disk = 2 gigabytes.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Let capacity of a thumb dives = x

And, Capacity of a compact disk = y

Then, For first condition;

''4 thumb drives and 1 compact disk have a total capacity of 18 gigabytes.''

We can formulate;

4x + y = 18  .... (i)

And, For second condition;

'3 compact disks and 4 thumb drives have a total capacity of 22 gigabytes.'

We can formulate;

4x + 3y = 22 .... (ii)

Solve the equation (i) and (ii) we get;

Subtract (ii) by equation (i) we get;

2y = 4

y = 2

And, 4x + 2 = 18

4x = 16

x = 4

So, Capacity of 1 thumb drives = 4 gigabytes.

Capacity of 1 compact disk = 2 gigabytes.

The x intercepts of the function given in the question will be equal to x = 6 and x = 3.

A function may be defined as an entity in which for one value of input there is only one value of output. The input value is the value of x variable, or the independent variable and the output value is the value of y variable or the dependent variable. For example, f(x) = y = x + 2, in this function for the value of input x = 1 the value of output is y = 3. The x intercept of a function may be defined as the point on the graph at which the line of function crosses the x axis. For finding the x intercept the y value or the value becomes zero. We are given the function g(x) = (1/4) (x - 6) (x - 3)

Now, g(x) = 0

(1/4) (x - 6) (x - 3) = 0

=> (x - 6) (x - 3) = 0

=> x = 6 and x = 3

Therefore, x intercepts are x = 6 and x = 3.

The rational number that can be written as a decimal in which one or more nonzero digits repeat is given by:

D. 5/9.

The set of rational numbers is composed by numbers that can be represented by fractions, such as numbers that have no decimal parts, or numbers in which the decimal parts are terminating or repeating.

For this problem, we have a focus on numbers that have repeating decimal part. The most known case is the division by 9, as when an integer that is not a multiple of 9 is divided by 9, the result is a decimal with a repeating decimal part.

To find the equivalent decimal to 5/9, we divide the numerator of 5 by the denominator of 9, hence:

5/9 = 0.55555...

The decimal digit 5 repeats infinitely, hence option D is correct.

m = -19 is the solution to the equation -2(m - 2) = -3(m + 5).

Given the data in the question;

To determine the numerical value of m, remove the parenthesis and simplify.

-2(m - 2) = -3(m + 5)

Apply distributive property

-2(m - 2) = -3(m + 5)

m(-2) - 2(-2) = m(-3) + 5(-3)

-2m + 4 = -3m - 15

Now, collect like terms by bring all values containing variable m to the left and all constant to the right side of the equation.

-2m + 3m = -15 - 4

m = -15 - 4
