1) 21 is 12.50% of 168.

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.

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.

The complete function is: [tex]y = x+55[/tex]

Step-by-step explanation:

the given table represents a linear function

The linear function is represented by:

[tex]y = mx+b[/tex]

Here

m is the slope of function and b is the y-intercept

In this case, m will be calculated as:

[tex]m= \frac{Change\ in\ y}{Change\ in\ x}\\= \frac{61-60}{6-5}\\= 1[/tex]

Hence the slope is 1.

Putting in the equation

[tex]y = x+ b[/tex]

To find the value of b, we will put any pair of x and y in the equation

[tex]61 = 5 + b\\b = 60-5\\b = 55[/tex]

Hence,

The final equation for linear function is:

[tex]y = x + 55[/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])

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.

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

19 = 9x - 25 is the numerical expression for 19 is 25 less than the product of 9 and a number

Solution:

Given statement:

19 is 25 less than the product of 9 and a number

We have to write the numerical expression for given statement

Let the number be "x"

From given information,

19 is 25 less than the product of 9 and a number

"product" means multiplication

And "less than" means subtracted or reduced by

Therefore,

Product of 9 and a number is translated as [tex]9 \times x[/tex]

Therefore, given statement is written numerically as:

19 = 25 less than the product of 9 and a number

[tex]19 = (9 \times x) - 25[/tex]

[tex]19=9x-25[/tex]

Thus the expression is found

Answer:

x=0

y=-3

6x-5y=15

x=y+3

Replace x with y+3

6(y+3)-5y=15

Distribute

6y+18-5y=15

y= -3

x=0

The solution to the system of equations is x = 0 and y = -3.

To solve the system of equations:

1. 6x - 5y = 15

2. x = y + 3

We can substitute equation 2 into equation 1 to find the value of x, and then use that value to find the value of y.

Substituting equation 2 into equation 1:

[tex]\[6(y + 3) - 5y = 15\]\[6y + 18 - 5y = 15\]\[y + 18 = 15\]\[y = 15 - 18\]\[y = -3\]\\[/tex]

Now that we have found y, we can substitute this value back into equation 2 to find x:

[tex]\[x = (-3) + 3\]\[x = 0\][/tex]

So, the solution to the system of equations is x = 0 and y = -3.

Final answer:

To estimate the remaining advertisement budget, calculate the total possible maximum expense and subtract it from the initial budget, resulting in an approximate remaining amount of $14,300.

Explanation:

Mr. Kellen's starting budget for advertisements was $50,000. If I assume that each of the 7 advertisements costs about the maximum amount which is $5,100, the estimated total cost would be 7 times $5,100, which equals $35,700. So, a reasonable estimate of the amount of money remaining after paying for the advertisements is $50,000 - $35,700 = $14,300.

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.
