Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

The daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.

Healthy diet:

A healthy diet helps protect against malnutrition in all its forms and is a foundation for health and development. It also helps to prevent noncommunicable diseases including diabetes, cardiovascular diseases, some cancers and other conditions linked to obesity.

In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.

\(\text{Total sodium = 1310 + 350 = 1660}\)

We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:

\(\frac{1660}{x} \frac{mg}{mg} = \frac{66.4}{100} \\\\66.4*x = 1660*100\\x=\frac{166000}{66.4} = \bold{2500\text{ mg}}\)

Hence, the daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

Listen the number is an even one-digit, so that means all odd numbers that are one-digit numbers are out so that means number A is wrong so its between B, C, and D. If you read the answer thoroughly through B, C, and D you will find one of the 2 x 6.7 is wrong. To find the correct answer to 2 x 6 and if the sum of 2 x 6 is equal to your 2 x 6 you have the correct answer! Btw I forgot the exact answer but I know it was either B or C.  

The correct option is The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4 and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet and 53.6 square feet.

The area of rectangle is the product of its length to its width.

i.e., Area of rectangle= length x width

Given:

The length is an even, one-digit whole number, and the width is 6.7 feet.

So, the least one digit even number is 2

then , the least area is = 2 x 6.7

                                      = 13.4

and, the greatest one digit even number is 8

then , the greatest area is = 8 x 6.7

                                      = 53.6

Hence, The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4 and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet and 53.6 square feet.

First, I need to decide what equation this is like.

I believe this is y=mx.

We know that x is typically the input, and m is the constant function.

Y is the output.

So the original function may have been y=200x.

The only difference is now we've been given something to apply to the equation, in place of x.

2. Imagine a cloning machine. Whatever you put in, you get a copy of, and the original thing you put in. Its function would be y=2x. Let's pretend we decided to put three things in; 3 would go where x is.

Y would be the result of 3 copies and their originals, or 2(3).

(6=2(3))

Now, when someone else decides to use the cloning machine, they may put any number in, but the only properties that will change are y and x, not m.

The function will remain y = 2x. Any number could go in place of x, and multiplying x by 2 will give you the y. As long as you have a different value for x, the y will never be the same.

3. So now we have an understanding of what it means, we see that we have been given an x value to insert; an input.

A more practical example could be someting with money. This won't be entirely realistic, because we are dealing with a fraction of a number and another large number.

4. I decided to go with flour. I wanted the 200 to represent pennies, or cents. Before I landed on this, I looked up the cost of flour per pound. I found that the average is .43 dollars, which isn't terribly close to two dollars. But maybe the flour is high quality, so we can stick with that.

5. Seeing that this equation, y=200x, means we are charging 200 cents, or two dollars, we can write a problem from here.

Sylvia is in charge of selling home-harvested flour from an organic farm. She charges two dollars per pound of flower. Today, her next-door neighbors hope to buy a ninth of pound of flour, and they insist on paying with pennies. How many pennies do they need to pay for their order?

Answer:

s = 0.06 c

Step-by-step explanation:

The sales tax rate is 6%, which means that the amount of sales tax (s) is 6% of the cost of an item (c).

Therefore, the equation that represents the relationship between c and s is:

s = 0.06 c

This equation expresses that the amount of sales tax (s) is equal to 6% (0.06) of the cost of the item (c).

Answer: B. s =  0.06c

Step-by-step explanation: If s is the total amount of sales tax then it has to be before the equal sign. Also the c is the amount of sales tax so it is multiplied by the sales tax rate (6% is converted to the decimal 0.06) 0.06 to get the total sales tax.
