Are Any Two Regular Polygons Similar. The Area Of The Smaller Figure Is About 390 Cm^2. Choose The Best

Answers

Answer 1

Answer:

The best estimate of the area of the larger figure is [tex]693\ cm^{2}[/tex]

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x-----> the corresponding side of the larger figure

y-----> the corresponding side of the smaller figure

so

[tex]z=\frac{x}{y}[/tex]

we have

[tex]x=12\ cm[/tex]

[tex]y=9\ cm[/tex]

substitute

[tex]z=\frac{12}{9}=\frac{4}{3}[/tex] -----> the scale factor

step 2

Find the area of the larger figure

we know that

If two figures are similar, then the ratio of its  areas is equal to the scale factor squared

Let

z----> the scale factor

x-----> the area of the larger figure

y-----> the area of the smaller figure

so

[tex]z^{2}=\frac{x}{y}[/tex]

we have

[tex]z=\frac{4}{3}[/tex]

[tex]y=390\ cm^{2}[/tex]

substitute and solve for x

[tex](\frac{4}{3})^{2}=\frac{x}{390}[/tex]

[tex](\frac{16}{9})=\frac{x}{390}[/tex]

[tex]x=390*16/9=693.33\ cm^{2}[/tex]

Which of the following points lies on the circle whose center is at the origin and whose radius is 10

Answers

Answer:

Step-by-step explanation:

No given points, but you can figure it out from the equation of the circle:

Centered at the origin means that a = b = 0 in

(x-a)^2+(y-b)^2=radius^2

leaving the following:

x^2+y^2=10^2

or x^2+y^2=100

then, from the given points, plug in the coordinates and check to see if it satisfies the equation.

For example, we already know that (10,0) will be on the circle, since it is centered at the origin with radius 10. We can check by plugging into the equation: (10)^2+0^2=100

100=100, so the point lies on the circle.

Side note:

To find which points are within the circle, the equation x^2+y^2<10^2 would have to be satisfied. In this case, (9,0) is one of infinitely many points which satisfies this equation, and therefore is inside the circle.

A yogurt company charges 72 cents for a 6 ounces container of yogurt. How much does it charge for an 8 ounce container?

Answers

Answer:

Step-by-step explanation:

If

72 cents ---> 6 ounces

Xcents  -----> 8 ounces

then

X = [(72)*(8)] / 6

X = 96 cents

Best regards

Final answer:

The yogurt company charges 12 cents per ounce. Therefore, an 8 ounce container would cost 96 cents.

Explanation:

The subject of this question is about cost per ounce for a yogurt container. First, we need to find the cost per ounce. This would be the total cost divided by the number of ounces. In this case, 72 cents for a 6 ounce container gives us 72/6 = 12 cents per ounce. If we then want to find the cost of an 8 ounce container, we can multiply the cost per ounce by the number of ounces. So, 12 cents per ounce times 8 ounces equals 96 cents. Therefore, an 8 ounce container would cost 96 cents.

The value of Jeunesse’s retirement account fell by $678.75 over a period of 3 months. What was the average change in value per month?

Answers

The average change in value per month is 2

$226.25 .

Final answer:

To find the average change in the value of Jeunesse's retirement account per month, you divide the total fall in value ($678.75) by the number of months (3). This results in an average monthly decrease of $226.25.

Explanation:

The problem requires us to compute the average change in Jeunesse's retirement account over a period of three months. The total change is $678.75. To calculate the average change for each month, we need to divide the total change by the number of months. This is also known as finding the average rate of change.

So, to compute it for Jeunesse's retirement account, we have:

Take the total change in the account, which is -$678.75. Divide this by the number of months, which is 3. This results in -$678.75 / 3 = -$226.25

Therefore, the average change per month in Jeunesse's retirement account is -$226.25.

What is the 50th term of the arithmetic sequence 32,27,22,17,12

Answers

Answer:

- 213

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a + (n - 1)d

where a is the first term and d the common difference

d = 27 - 32 = - 5 and a = 32, hence

[tex]a_{50}[/tex] = 32 + (49 × - 5) = 32 - 245 = - 213

The 50th term of the arithmetic sequence is -213.and this can be determined by using the [tex]\rm T^{th}[/tex] term of the arithmetic sequence formula.

Given :

Arithmetic sequence  ---  32,27,22,17,12

The difference of the arithmetic operation is given by the formula:

[tex]a_2-a_1 = 27 - 32 = - 5[/tex]

The [tex]\rm T^{th}[/tex] term of the arithmetic sequence is given by the formula:

[tex]\rm T_n = a + (n-1)d[/tex]

where a is the first term, n is the total number of terms, d is the difference, and [tex]\rm T^{th}[/tex] is the term of the arithmetic sequence.

[tex]\rm T_{50} = 32 - (50-1)5[/tex]

[tex]\rm T_{50} = 32 - (49)\times 5[/tex]

[tex]\rm T_{50} = -213[/tex]

The 50th term of the arithmetic sequence is -213.

Martha has a bidget for groceries etc. She spent 20% of her budget on groceries. If martha spent $42.00 on groceries how much is her budget.

THIS MATH IS CONFUSING ME

Answers

Final answer:

Martha's total budget for groceries is calculated using the proportion of the amount spent, which is $42.00 corresponding to 20% of her budget. By cross-multiplying and dividing, we find that her total budget is $210.00.

Explanation:

To figure out Martha's budget for groceries based on the percentage she spent, we can use proportions. If Martha spent $42.00 on groceries, which represents 20% of her budget, we can set up the proportion as follows:

20% (the percentage spent on groceries) / 100% (the total budget) = $42.00 (amount spent on groceries) / B (total budget)

Now, we solve for B using cross-multiplication:

20% * B = 100% * $42.00

0.20 * B = $42.00

B = $42.00 / 0.20

B = $210.00

Hence, Martha's total budget is $210.00.

Looking at 2nd step of Tyler's work, we can see that he successfully used this rule with the exponent of x, but forgot to change the sign of the power of y to 9.

Since both the powers were negative when in the numerator, they should both be positive when taken to denominator. Hence, the correct answer is "Both powers should be in the denominator with positive exponents"

In an expression, there are terms, which are a number(s) that are combined by multiplication but separated by addition (if you see subtraction it's just adding the negative version of the number).  In this case, there are 5 terms.  A term can have a variable or it can be a constant.  A constant is just a number.  We can combine constants.  For example, in this case, we can combine 22 and -8 to get 14.  (just adding).  If it has a variable, we can only combine two terms if they have the same variable, so 5m and -4m can be combined to get m.  We replace the terms we have combined with the combined terms so we have m + 7n + 14.

Which is the missing term? (10x - 4x^2)-(7x+ ? ) = 3x-6x^2

Answers

2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.

Answer:

The missing term is   -2x²

Step-by-step explanation:

It is given that,

(10x - 4x² ) - (7x + ?) = 3x - 6x²

To find the missing term

Let 'M' be the missing term we can write the above equation,

(10x - 4x² ) - (7x + M) = 3x - 6x²

⇒ 10x - 4x²  - 7x + M = 3x - 6x²

⇒ 10x - 7x - 4x² + M = 3x - 6x²

⇒ 3x - 4x² + M = 3x - 6x²

 M = -6x² + 4x²

 M = -2x²
