Which choices show the ratio of the area of the smaller rectangle to the area of the larger rectangle? Select three options.
Answer:
The options b) ,c) and e) are correctThe three choices shows the ratio of the area of the smaller rectangle to the area of the larger rectangle are b)[tex](\frac{4}{16})^2[/tex] , c) [tex]\frac{12}{192}[/tex] and e) [tex](\frac{3}{12})^2[/tex]Step-by-step explanation:
Given that a large rectangle has a length of 16 and width of 12.
A smaller rectangle has length of 4 and width of 3
To show the ratio of the area of the smaller rectangle to the area of the larger rectangle:we know that "If two figures are similar, the the ratio of its areas is equal to the scale factor squared"
From the given scale factor is [tex]\frac{1}{4}[/tex]
Let z be the scale factor
Let x be the area of the smaller rectangle
Let y be the area of the large rectangle
[tex]z^2=\frac{x}{y}[/tex]
Since scale factor is [tex]\frac{1}{4}[/tex] hence [tex]z=\frac{1}{4}[/tex]
we have [tex]z^2=(\frac{1}{4})^2[/tex]
[tex]=\frac{1}{16}[/tex]
∴ [tex]z^2=\frac{1}{16}[/tex]
Now show that the ratio of the area of the smaller rectangle to the area of the larger rectangle with each options.
a) [tex]\frac{4}{16}[/tex]
[tex]\frac{4}{16}=\frac{1}{4}[/tex]
Compare with [tex]\frac{1}{16}[/tex] we get,
[tex]\frac{1}{4}\neq \frac{1}{16}[/tex]
Hence it is not possible.b) [tex](\frac{4}{16})^2[/tex]
[tex](\frac{4}{16})^2=\frac{16}{256}[/tex]
[tex]=\frac{1}{16}[/tex]
Compare with [tex]\frac{1}{16}[/tex] we get,
[tex]\frac{1}{16}=\frac{1}{16}[/tex]
This implies that the ratio of the area of the smaller rectangle to the area of the larger rectangle.c) [tex]\frac{12}{192}[/tex]
[tex]=\frac{1}{16}[/tex]
Compare with [tex]\frac{1}{16}[/tex] we get,
[tex]\frac{1}{16}=\frac{1}{16}[/tex]
This implies that the ratio of the area of the smaller rectangle to the area of the larger rectangle.d) [tex](\frac{4}{12})^2[/tex]
[tex]=\frac{16}{144}[/tex]
[tex]=\frac{1}{9}[/tex]
Compare with [tex]\frac{1}{16}[/tex] we get,
[tex]\frac{1}{9}\neq \frac{1}{16}[/tex]
Hence it is not possible.e) [tex](\frac{3}{12})^2[/tex]
[tex]=\frac{9}{144}[/tex]
[tex]=\frac{1}{16}[/tex]
Compare with [tex]\frac{1}{16}[/tex] we get,
[tex]\frac{1}{16}=\frac{1}{16}[/tex]
This implies that the ratio of the area of the smaller rectangle to the area of the larger rectangle.∴ options b) ,c) and e) are correctThe three choices shows the ratio of the area of the smaller rectangle to the area of the larger rectangle are b)[tex](\frac{4}{16})^2[/tex] , c) [tex]\frac{12}{192}[/tex] and e) [tex](\frac{3}{12})^2[/tex]Answer:

A population of 110,000 grows 3% per years 15 years. How much will the population. How much will the population be after 15 years? Terms of x
Answer:
The population be after 15 years is 171376.
Step-by-step explanation:
Given : A population of 110,000 grows 3% per years 15 years.
To find : How much will the population be after 15 years?
Solution :
Exponential growth population model is given by,
[tex]P(t)=P_o(1+r)^t[/tex]
Where,
P(t) is the population at time (t)
[tex]P_o=110,000[/tex] is the initial value of the population
r=3%=0.03 is the annual rate of growth
t=15 is the time in years.
Substitute the value,
[tex]P(t)=110000(1+0.03)^{15}[/tex]
[tex]P(t)=110000(1.03)^{15}[/tex]
[tex]P(t)=110000\times 1.5579[/tex]
[tex]P(t)=171376.41[/tex]
Therefore, the population be after 15 years is 171376.
Final answer:
The future population after 15 years of 3% annual growth starting with a population of 110,000 is calculated using the exponential growth formula, resulting in approximately 171,380 people.
Explanation:
To calculate the future population given a current population, growth rate, and number of years, you can use the formula for exponential growth:
P(t) = P0 ×[tex](1 + r)^{t}[/tex]
Where:
P(t) is the population after t years.
P0 is the initial population.
r is the annual growth rate (expressed as a decimal).
t is the time in years.
In this case, the initial population (P0) is 110,000, the growth rate (r) is 3% or 0.03, and the time (t) is 15 years.
Applying these values to the formula:
P(15) = 110,000 × (1 + 0.03)¹⁵
Now we compute the amount (rounded to the nearest whole number):
P(15) = 110,000 × 1.03¹⁵
P(15) ≈ 110,000 × 1.558
P(15) ≈ 171,380
Therefore, the population after 15 years will be approximately 171,380 people.

Answer:
i dont see a picture
Step-by-step explanation:
Dado dos ángulos complementarios, uno mide (2x + 10) y el otro (x + 20),
calcula el valor de x
Answer:
El valor de x es igual a 20 o x = 20.
Step-by-step explanation:
Lo primero que se debe saber es que dos ángulos complementarios suman un ángulo recto o 90º.
Supongamos que el valor de un ángulo [tex] \\ \alpha[/tex] y un ángulo [tex] \\ \beta[/tex] valen:
[tex] \\ \alpha = 2x + 10[/tex] [1]
[tex] \\ \beta = x + 20[/tex] [2]
Como la suma de [tex] \\ \alpha + \beta = 90[/tex] [3]
Entonces
[tex] \\ \alpha + \beta = (2x + 10) + (x + 20) = 90[/tex]
Sumamos los factores comunes entre si:
[tex] \\ (2x + x) + (10 + 20) = 90[/tex]
Para la primera expresión debemos recordar que se suman sólo los coeficientes. Así:
[tex] \\ (2 + 1)x + (10 + 20) = 90[/tex]
[tex] \\ 3x + 30 = 90[/tex]
Para despejar la incógnita x, debemos tener en cuenta que una igualdad no se altera si se suma, se resta, se multiplica o divide un mismo valor a cada lado de ella. Por esta razón, para despejar 3x, lo primero que podemos hacer es sumar -30 a cada lado de la expresión (lo que es igual a restar 30 a cada lado de la misma). Así tenemos:
[tex] \\ 3x + 30 - 30 = 90 - 30[/tex]
[tex] \\ 3x + 0 = 90 - 30[/tex]
[tex] \\ 3x = 60[/tex]
Ahora dividimos cada miembro de la igualdad entre 3 (o multiplicamos cada lado de la igualdad por [tex] \\ \frac{1}{3}[/tex] ):
[tex] \\ \frac{3}{3}x = \frac{60}{3}[/tex]
Como sabemos que:
[tex] \\ \frac{3}{3} = 1[/tex]
Entonces:
[tex] \\ 1*x = \frac{60}{3}[/tex]
[tex] \\ x = \frac{60}{3}[/tex]
[tex] \\ x = 20[/tex]
De esta manera, el valor de x es igual a 20 o x = 20.
Lo anterior lo podemos comprobar considerando las ecuaciones [1], [2] y [3]. Así tenemos que:
[tex] \\ \alpha = 2x + 10[/tex] [1]
Sustituimos x por el valor de 20:
[tex] \\ \alpha = 2*20 + 10 = 40 + 10 = 50[/tex]
[tex] \\ \beta = x + 20[/tex] [2]
Hacemos lo mismo para [2]:
[tex] \\ \beta = 20 + 20[/tex]
[tex] \\ \beta = 40[/tex]
De esta manera:
[tex] \\ \alpha + \beta = 90[/tex] [3]
[tex] \\ 50 + 40 = 90[/tex]
Write the following finite decimals as fractions (you do not need to reduce to lowest terms).
1, 1.4, 1.41, 1.414, 1.4142, 1.41421
Answer:
To make any decimal a fraction, you just add a denominator that has one more digit. Ex: .5 has 1 digit. So add 1 zero, and you get 10 as the denominator.
1, 14/10, 141/100, 1414/1000, 14142/10000, 141421/100000
The given decimals can be converted to fractions based on the decimal place values. Therefore, 1 converts to 1, 1.4 to 14/10, 1.41 to 141/100, 1.414 to 1414/1000, 1.4142 to 14142/10000, and 1.41421 to 141421/100000.
Explanation:The numbers given can be written as fractions by considering the place value of the digits after the decimal point. Here is the conversion:
1 can be written as 1/1 or just 1 as there is no decimal part.1.4 can be written as 14/10 because 4 is in the tenths place.1.41 is 141/100 as 1 is in the hundredth place.1.414 can be written as 1414/1000 since 4 is in the thousandths place.1.4142 is 14142/10000 as 2 is in the ten-thousandths place.1.41421 can be written as 141421/100000 because 1 is in the hundred-thousandths place.Learn more about Decimal to Fraction Conversion here:https://brainly.com/question/31738948

For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. What is definitely true about x = 7? (2 points)
Both m(x) and p(x) cross the x-axis at 7.
Both m(x) and p(x) cross the y-axis at 7.
Both m(x) and p(x) have the same output value at x = 7.
Both m(x) and p(x) have a maximum or minimum value at x = 7.
Answer:
Both m(x) and p(x) have the same output value at x = 7
Step-by-step explanation:
for two functions m(x) and p(x) we know that the solution to the equation :
m(x)=p(x) is the x-value of the point of intersection of the two curves.
i.e. at this point the output value i.e. the value which is obtained on putting the input value i.e. 'x' is same for the two functions m(x) and p(x).
Hope This Helped
When m(x) = p(x) at x = 7, it implies that both functions produce the same output value at x = 7, representing the equality of the functions.
Both m(x) and p(x) have the same output value at x = 7. When m(x) = p(x) at x = 7, it means that both functions produce the same output value at x = 7. This is the defining characteristic of the statement made.
For a given x value of 7, both m(x) and p(x) will yield an identical result, indicating that they are equal at that specific point. This does not necessarily mean they cross the x-axis, y-axis, or have maximum or minimum values at x = 7, but rather that their outputs are the same at this particular x value.
Therefore, the correct statement about x = 7 when m(x) = p(x) is that both m(x) and p(x) have the same output value at x = 7.

two people were doing yard work for 1 hour and 35 minutes then they stopped for lunch at 1:20pm at what time did they start doing yard work?
Answer: The answer would be at 11:45.
Step-by-step explanation: First I though, if they stoppedd for lunch at 1:20 and they've been doing yard work for 1 hour and 35 minutes, I would subtract. 1 hour taken away from 1:20 would be 12:20. Then, since it would be hard to subtract 35 minutes from 12:20, 35 minutes - 20 minutes = 15 minutes. 12:20 subtract 20 minutes = 12:00. 12:00 - 15 minutes equal to 11:45. I hope this helps. I know this explanation can be confusing but it's the best I can do at the moment.

There are 8 green, 10 purple, 6 red and 16 blue markers in a box. A marker is chosen,replaced and then another marker is chosen. Find the probability that neither marker is red.
The probability that neither marker chosen from the box is red is 72.25%
Explanation:The probability that neither marker chosen is red can be calculated by finding the probability of not picking a red marker twice. There are a total of 40 markers (8 green, 10 purple, 6 red, and 16 blue). Therefore, the probability of not picking a red marker on the first try is 34/40 or 0.85 (since there are 34 non-red markers).
Because the marker is replaced, the conditions remain the same for the second draw. Hence, the probability of also not picking a red marker in the second draw remains at 0.85.
As these are two independent events, the total probability of neither marker being red is found by multiplying the probabilities of the individual events. Hence, 0.85 * 0.85 = 0.7225. Hence the probability that neither marker is red is 0.7225 or 72.25%.

To find the probability that neither marker is red, calculate the probability of selecting a non-red marker on each draw and multiply the probabilities together.
Explanation:To find the probability that neither marker is red, we need to calculate the probability of selecting a non-red marker on each draw.
The total number of markers in the box is 8 (green) + 10 (purple) + 6 (red) + 16 (blue) = 40.
The probability of selecting a non-red marker on the first draw is (8 + 10 + 16)/40 = 34/40 = 17/20.
Since the marker is replaced back in the box, the probability of selecting a non-red marker on the second draw is also 17/20.
The probability that neither marker is red is the product of the individual probabilities: (17/20) * (17/20) = 289/400.
