a rectangle has an area of 25 square feet. a similar rectangle has an area of 200 square feet. what is the ratio of the areas of these similar rectangles?

I think it's histograms for the first blank; distribution for the second blank; frequency for the third and final blank.

Hope this helps please let me know if I'm wrong :)))

Histograms show the distribution and frequency for a set of values. Distribution is how the values are spread out or grouped, and frequency is how often a value occurs in a set of numbers.

A frequency distribution is like a detailed count of all the different values or groups of values in a data set. When data are collected, a histogram provides a visual representation of this distribution. The distribution of the data can be divided into various classes or bins, where the count or frequency of data falling into each bin is tallied. This tally helps to visualise patterns such as the center, spread, and overall shape of the data.
The histogram consists of contiguous rectangles, with the height of each bar corresponding to the frequency of data points within that class interval. The horizontal axis (x-axis) typically represents the values or categories of the dataset, while the vertical axis (y-axis) represents the frequency of occurrences. This graphical tool allows us to quickly ascertain which values are more prevalent and identify the spread or variability of the data, as well as the center, which is considered the middle or typical value of the dataset.

Answer:

Option C. is the correct option.

Step-by-step explanation:

Clara found the product of (3 - 6y²) and (y² + 2) and she did it as below

(3 - 6y²)(y² + 2) = 3(y²) + (-6y²)×2 = 3y² - 12y² = -9y²

She did the step wrong as highlighted above. She did not use the distributive property correctly.

Now we will do it in a correct way.

(3 - 6y²)(y²+2) = 3(y² + 2) - 6y²(y² + 2)

= 3y^{2}+6-6y^{4}-12y^{2}=-6y^{4}-9y^{2}+6

Therefore Option C. is the correct answer.

Julian is using the concept testing method of advertising which involves testing ad ideas before product development. It helps in determining consumer reactions and minimizing errors.

The method Julian is using is called the concept testing method in advertising. In concept testing, ad ideas and concepts are tested by companies before the actual development of the product. Concept tests are ways for advertisers to determine the reaction of consumers to a proposed product or service before it hits the market, thus minimizing errors and financial risks. For instance, in Julian's case, this would imply presenting his ad idea, which showcases a new mobile phone, to a selected group of people and then collecting their feedback. The feedback can then be used to refine the ad and the product itself, ensuring that the mobile phone meets the expectations and needs of the targeted consumers.

Answer: The shortest side is 9ft

Step-by-step explanation: If the longest side is identified as 15 ft, then we already have our hypotenuse (the longest side in a right angled triangle).

If the shortest side is labelled as x, then the third side of the triangle would be labelled as 3x - 15 (15 less than three times the shortest side).

Now we have three sides of a triangle which we can label as 15, x and 3x - 15

By applying the Pythagoras theorem, AC² = AB² + BC²

(Where AC is the hypotenuse and AB and BC are the other two sides)

15² = X² + (3x-15)²

By expansion, (3x-15)² becomes 9x² - 90x + 225

Hence, 225 = X² + 9X² - 90X + 225

225 = 10X² - 90X + 225

Subtract 225 from both sides of the equation

10X² - 90X = 0

Factorize the left hand side of the equation by 10x

10x (x - 9)= 0

Therefore, either

10x = 0 OR

x - 9 = 0

If 10x=0, then x=0. OR

If x - 9 = 0, then x = 9

The length of the shortest side is 9ft.

Answer:

C

Step-by-step explanation:

Slope-intercept form is y=mx+b. Y is y, m is the slope, x is x, and b is the y-intercept. The first thing you do is figure out the slope. The equation is (y2-y1)/(x2-x1). Then take 2 points from the table and substitute them in. I'll use the bottom two points: (4-2)/(2-1). You should get 2 as your answer. Substitute this in for m. Take a point from the table and substitute y in for y, x in for x. I'll use the last point: 4=2(2)+b. If I simplify further, I get 4=4+b, which means b is 0, and we won't need to put it in the equation.

Figure out the answer using the process of elimination: we know that because b=0, the answer can't be A or B. The slope is positive 2, which means that the answer can't be D. So it has to be C.

Work Shown for part (i)

One base of triangle PQR is QR = 4

If the base is QR, then the height is PL = 5, which is perpendicular to QR.

area of triangle PQR = (1/2)*base*height

area of triangle PQR = (1/2)*QR*PL

area of triangle PQR = (1/2)*4*5

area of triangle PQR = 10

---------------------------------

Work Shown for part (ii)

Another base for triangle PQR is PR = 8

Imagine rotating triangle PQR so that PR is completely horizontal and flat.

Note: the diagram implies that MR = 8, but instead it's actually PR = 8

For the base PR, the perpendicular height is QM, which we'll label as x for now

area of triangle PQR = (1/2)*base*height

area of triangle PQR = (1/2)*PR*QM

area of triangle PQR = (1/2)*8*x

area of triangle PQR = 4*x

From part (i), we can set 4x equal to 10 since we know the triangle PQR has area 10 square cm.

4x = 10

4x/4 = 10/4

x = 10/4

x = (5*2)/(2*2)

x = 5/2

x = 2.5

Answer: $7,864.32

Step-by-step explanation:

First you would do 100% -20% which would give you 80% (0.8)

1st year : $24,000 x 0.8 = 19,200

Then take your answer and times it by 0.8 again until you get to the 5th year

2nd year : $19,200 x 0.8 = $15,360

3rd year : $15,360 x 0.8 = $12,288

4th year : $12,288 x 0.8 = $9,830.40

5th year : $9,830.40 x 0.8 = $7,864.32

Therefore your final answer is $7,864.32

Final answer:

The resale value of the car after 5 years will be approximately $7,864.32.

Explanation:

To find the resale value of the car after 5 years, we need to calculate the depreciation rate each year and then apply it to the original purchase price. Since the resale value decreases by 20% each year, we can calculate the resale value after 5 years as follows:

After the first year, the resale value will be 80% of the original purchase price: $24,000 * 0.8 = $19,200.

After the second year, the resale value will be 80% of the previous year's resale value: $19,200 * 0.8 = $15,360.

After the third year, the resale value will be 80% of the previous year's resale value: $15,360 * 0.8 = $12,288.

After the fourth year, the resale value will be 80% of the previous year's resale value: $12,288 * 0.8 = $9,830.40.

After the fifth year, the resale value will be 80% of the previous year's resale value: $9,830.40 * 0.8 = $7,864.32.

Therefore, the resale value of the car after 5 years will be approximately $7,864.32.

Step-by-step explanation:

4 1/2=9/2

3 4/5=19/5

9/2-19/5=45/10-38/10=7/10

Answer:

20%

Step-by-step explanation:

let the percent be p

rewriting the expression:

p% of 170 is 34

or mathematically,

p% x 170 = 34

(p / 100) x 170 = 34   (divide both sides by 170)

p/100 = 34/170  (multiply both sides by 100)

p = (34 / 170)  x 100

p = 20

hence 34 is 20% of 170

There are 43 nickels in the piggy bank.

Step-by-step explanation:

Final answer:

To find the number of nickels in the piggy bank, you can set up a system of equations. By solving the system, it is determined that there are 43 nickels.

Explanation:

To find the number of nickels in the piggy bank, we need to set up a system of equations. Let's assume that the number of nickels is 'x' and the number of dimes is 'y'.

We know that there are a total of 91 coins, so we can write the equation: x + y = 91.

We also know that the value of the nickels is 5 cents and the value of the dimes is 10 cents. The total value of the coins is $6.95, so we can write the equation: 5x + 10y = 695.

Solving this system of equations will give us the number of nickels.

First, let's multiply the first equation by 5 to eliminate 'x'.

5x + 5y = 455

Next, subtract this new equation from the second equation.

(5x + 10y) - (5x + 5y) = 695 - 455

5y = 240

y = 48

Finally, substitute the value of 'y' back into the first equation to find 'x'.

x + 48 = 91

x = 43

Therefore, there are 43 nickels in the piggy bank.
