Answer:

8 and 5

Step-by-step explanation:

The sum of 8 and 5 implies

8 + 5 = 13

The difference between 8 and 5 implies:

8 - 5 = 3

Therefore, the sum of two numbers that gives 13 and their difference being 3 are 8 and 5.

Plot the vertices A'(-12, 9), B'(9, 3), and C'(6, -3) on the coordinate plane. Label them as A', B', and C', respectively.

To determine the coordinates of the dilated triangle A'B'C', we can follow these steps:

1. Find the coordinates of the original triangle's vertices: A(-4, 3), B(3, 3), and C(2, -1).

2. Dilate each vertex from the origin by a scale factor of 3. This means we will multiply the x and y coordinates of each vertex by 3.

- For vertex A: Multiply -4 by 3 to get -12 and multiply 3 by 3 to get 9. Therefore, the coordinates of A' are (-12, 9).
- For vertex B: Multiply 3 by 3 to get 9. The y-coordinate remains the same at 3. Therefore, the coordinates of B' are (9, 3).
- For vertex C: Multiply 2 by 3 to get 6 and multiply -1 by 3 to get -3. Therefore, the coordinates of C' are (6, -3).

3. Plot the vertices A'(-12, 9), B'(9, 3), and C'(6, -3) on the coordinate plane. Label them as A', B', and C', respectively.

Note: The original triangle ABC remains unchanged on the coordinate plane.

By following these steps, you will have successfully determined the coordinates of the dilated triangle A'B'C' and plotted it on the coordinate plane.

For 57 to be a prime number, it would have been required that 57 has only two divisors, i.e., itself and 1. However, 57 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 57 = 3 x 19, where 3 and 19 are both prime numbers.

Answer: No

Step-by-step explanation: For 57 to be a prime number, it would have been required that 57 has only 2 divisors, ie itself and 1. How ever 57 is a semiprime because it is the product of a two non- necessarily distinct prime numbers. inderd, 57= 3×19, where 3 and 19 are prime numbers.

Step-by-step explanation:

Without the actual data, we cannot definitively decide the correct exponential model for the population of the District of Columbia. The options provided all share the same initial quantity, with different growth factors. To pick one, we would need data on the annual population growth or decline.

The question is asking us to choose an exponential model of the form a ∙ bx that best represents the population of the District of Columbia for years after 2005. As we are not provided actual data on the population growth or decline, we can't definitively choose between the options. In this kind of model, a is the initial quantity (population in the year 2005), and b is the growth factor per the time period (in this case: annually). In all options provided we have the same initial quantity '550,521'. The difference is in the growth factors .993, .990, .992, and .991. Without the actual data, we cannot definitively pick one. However, if the population is declining each year, you'd expect the growth factor to be less than 1. In case if it's growing you'd expect it to be more than 1.

Answer: 19 /4 or 4 3/4

Step-by-step explanation:

Turn 67/8 into a improper fraction, which is 55/8

Next, also convert 21/8 into an improper fraction, which is 17/8

Next, subtract 17/8 from 55/8 and you should get 38/8

Last, simplify 38/8 to do so divide 38/8 by 4/4 and you should get 19/4 and if you want it's optional to turn it into a mixed number.  

The estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.

To find the difference of two fractions means that subtract one from the other.

Thus:

Difference between 6 7/8 and 2 1/8 = 6 7/8 - 2 1/8

Change the mixed fraction to improper fractions

55/8 - 17/8

= (55 - 170/8

= 38/8 = 19/4

= 4 3/4 = 4.75 ≈ 5.

Therefore, the estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.

Answer:

15. ∠ABE = 50°

16. ∠EBD = 10n - 19

Step-by-step explanation:

If [tex]$ \overline{\textbf{BE}} $[/tex] bisects ∠ABD then we have ∠ABE = ∠DBE

So, we will have: (6x + 2)° = (8x - 14)°

⇒ 6x + 2 = 8x - 14

⇒ 8x - 6x = 14 + 2

⇒ 2x =16

⇒ x = 8

∴ ∠ABE = 6(8) + 2

= 48 + 2

= 50°

∴∠ABE = 50°

16. If [tex]$ \overline{\textbf{BE}} $[/tex] bisects ∠ABD then ∠ABE + ∠EBD = ∠ABD

⇒(12n - 8) + ∠EBD = (22n - 11)

⇒ ∠EBD = 22n - 11 - 12n + 8

⇒ ∠EBD = 10n - 3

Hence, the answer.

Laura and Erica will both have made 16 blankets in one more day.

Step-by-step explanation:

i) Erica has made 10 blankets already.

ii) Erica can make 6 blankets more per day

iii) Laura has completed 6 blankets already

iv) Laura can complete 10 more blankets per day.

v) Let x be the number of days to the point when they will have completed the same number of blankets

vi) Therefore the number of blankets that Erica makes till x days is = to the number of blankets that Laura makes till x days

vi) therefore 10 + 6x  = 6 + 10x    ⇒   4x  = 4    ⇒ x = 1 day

vii) Therefore Laura and Erica will both have made 16 blankets in one more day.

Answer:

2 weeks and 5 days

Step-by-step explanation:

Final answer:

Raphael ran for a total of 5 weeks, calculated by dividing the total number of days he ran (35 days) by the number of days in a week (7 days).

Explanation:

Raphael runs for 35 days in a row, and we need to calculate how many weeks he runs. A week consists of 7 days. To find out the number of weeks Raphael ran, we divided the total number of run days by the number of days in a week.

Number of weeks = Total run days / Days in a week = 35 / 7 = 5

Therefore, Raphael ran for 5 weeks, illustrating the duration of his consistent running routine in terms of weeks. This computation provides a clear understanding of the duration of Raphael's running streak in a familiar time frame, aiding in tracking and planning his exercise regimen.

After 28 years, there will be approximately $48,505.29 in the account.

To calculate the amount of money that will be in the account after 28 years with an annual interest rate of 8.25%, we can use the formula for compound interest:

[tex]\[ A = P \times (1 + r)^n \][/tex]

Where:

- A  is the amount of money accumulated after  n years, including interest.

- P  is the principal amount (the initial amount of money), which is $6700 in this case.

- r  is the annual interest rate (in decimal form), which is 8.25% or 0.0825.

- n is the number of years, which is 28 in this case.

Plugging in the values into the formula:

[tex]\[ A = 6700 \times (1 + 0.0825)^{28} \][/tex]

Calculating the value:

[tex]\[ A = 6700 \times (1.0825)^{28} \][/tex]

[tex]\[ A \approx 6700 \times 7.2417 \][/tex]

[tex]\[ A \approx 48,505.29 \][/tex]

Answer:

2x⁴y²

Step-by-step explanation:

The question gives us the expression;

12x⁷y³ ÷ 6x³y

We are supposed to simplify the expression;

First we could divide the digits;

12 ÷ 6 = 2

Then we divide the like terms;

x⁷ ÷ x³

This means;

[tex]=\frac{x*x*x*x*x*x*x }{x*x*x}[/tex]

[tex]= x*x*x*x[/tex]

[tex]=x^4[/tex]

y³ ÷ y

That is;

[tex]=\frac{y*y*y}{y}[/tex]

[tex]=y*y[/tex]

[tex]=y^2[/tex]

Therefore, the simplified expression will be 2x⁴y²

Answer:

The values are [tex]x=\frac{7}{2}[/tex] and [tex]y=\frac{5}{2}[/tex]

The solution is ([tex]\frac{7}{2}[/tex],[tex]\frac{5}{2}[/tex])

Step-by-step explanation:

Given equations are [tex]5x=7y\hfill (1)[/tex] and

[tex]x+7y=21\hfill (2)[/tex]

To solve the given equations by elimination method:

Equation (1) can be written as  [tex]5x-7y=0\hfill (3)[/tex] and

Now multiply the equation (2) into 5 we get

[tex]5x+35y=105\hfill (4)[/tex]

Subtracting equations (3) and (4) we get

[tex]5x-7y=0[/tex]

[tex]5x+35y=105[/tex]

_________________

-42y=-105

[tex]y=\frac{105}{42}[/tex]

Therefore [tex]y=\frac{5}{2}[/tex]

Substitute  the value [tex]y=\frac{5}{2}[/tex] in equation (1) we get

[tex]5x=7\times \frac{5}{2}[/tex]

[tex]5x=\frac{35}{2}[/tex]

[tex]x=\frac{35}{2\times 5}[/tex]

[tex]x=\frac{7}{2}[/tex]

Therefore [tex]x=\frac{7}{2}[/tex] and [tex]y=\frac{5}{2}[/tex]

The solution is ([tex]\frac{7}{2}[/tex],[tex]\frac{5}{2}[/tex])

Answer:

The equation of the line is:  y = x + 4

Step-by-step explanation:

When we are given two points passing through a line, we can find the equation of the line by using two - point form.

Two - point form:    [tex]$ \frac{\textbf{y - y}_\textbf{1}}{\textbf{y}_{\textbf{2}} \textbf{-} \textbf{y}_{\textbf{1}}} = \frac{{\textbf{x - x}_\textbf{1}}}{\textbf{x}_{\textbf{2}} \textbf{-} \textbf{x}_{\textbf{1}} }$[/tex]

where [tex]$ (x_1, y_1) \hspace{3mm} \& \hspace{3mm} (x_2, y_2) $[/tex] are the points passing through the line.

Here, let us take two points (can be any two):

[tex]$(x _1, y_1) = (1, 5) $[/tex] and

[tex]$ (x_2, y_2) = (5, 9) $[/tex]

Therefore, we have:

[tex]$ \frac{y - 5}{9 - 5} = \frac{x - 1}{5 - 1} $[/tex]

[tex]$ \iff \frac{y - 5}{4} = \frac{x - 1}{4} $[/tex]

[tex]$ \iff y - 5 = x - 1 $[/tex]

[tex]$ \implies y = x - 1 + 5 $[/tex]

[tex]$ \implies y = \textbf{x + 4} $[/tex] which is the required answer.

2) 4% of 150 is 6.

3) 1% of 500 is 5.

4) 62% of 50 is 31.

5) 15% of 15 is 2.25

6) 40 percent of 25 is 10.

Step-by-step explanation:

1). 21 is what percent of 168.

Let,

x be the percent.

Therefore,

x% of 168 = 21

[tex]\frac{x}{100}*168=21[/tex]

[tex]1.68x=21[/tex]

Dividing both sides by 1.68

[tex]\frac{1.68x}{1.68}=\frac{21}{1.68}\\x=12.50[/tex]

21 is 12.50% of 168.

2). What is 4 percent of 150.

4% of 150 = [tex]\frac{4}{100}*150[/tex]

4% of 150 = [tex]\frac{600}{100} = 6[/tex]

4% of 150 is 6.

3) 1 percent of 500 is what number

1% of 500 = [tex]\frac{1}{100}*500[/tex]

1% of 500 is 5.

4) what number is 62 percent of 50

62% of 50 = [tex]\frac{62}{100}*50[/tex]

62% of 50 = [tex]0.62*50=31[/tex]

62% of 50 is 31.

5) 15 percent of 15 is what

15% of 15 = [tex]\frac{15}{100}*15[/tex]

15% of 15 = [tex]\frac{225}{100}=2.25[/tex]

15% of 15 is 2.25

6) 40 percent of 25 is what number

40% of 25 = [tex]\frac{40}{100}*25[/tex]

40% of 25 = [tex]\frac{1000}{100}=10[/tex]

40 percent of 25 is 10.
