If y varies directly with x when y=16 and x=2.1, what is the value of x when y=4
Rounded to the nearest tenth
Answer: 0.53
Step-by-step explanation:
From variation ,
y ∞ x ------------------------------------------------1
y = kx , where k is called the constants of proportionality and must be calculated first before proceeding.
substitute for the values in equation 2 ,below
y = kx -----------------------------------------------2
16 = k2.1
k = 16/2.1
Now to find the value of x, make x the subject of the formula in equation 2
x = y/k
= 4/ 16/2.1
= 4 ÷ 16/2.1
= 4 x 2.1/16
= 2.1/4
= 0.525
≅ 0.53
What is the x-intercept of
x + 9y = 1
6x-5y=15. X=y+3. X= ?y=?
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.

A square is cut out of a circle whose diameter is approximately 14 feet. What is the approximate area (shaded region) of the remaining portion of the circle in square feet?
A.25 feet
B.40 feet
C.50 feet
D.80 feet
Answer:)
C. 50 feet^2
Step-by-step explanation:
Area of circle

19 is 25 less than the product of 9 and a number numerical expression
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:
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.
1). 21 is what percent of 168. 4) what number is 62 percent of 50
2). What is 4 percent of 150. 5) 15 percent of 15 is what
3) 1 percent of 500 is what number 6) 40 percent of 25 is what number
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.

Which is the best estimate of the difference between 6 7/8 and 2 1/8
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.
What is the Difference between Fractions?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:

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.
Explanation: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.

Mr. Kellen had an advertising budget of $50,000 to spend on advertisements for his company.
• He advertised in 7 different magazines.
• The least expensive advertisement cost $4,200.
• The most expensive advertisement cost $5,100.
Which value is a reasonable estimate of the amount of money remaining in the budget after Mr. Kellen paid for the 7 advertisements
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.

5x=7y, X+7Y=21 how do u solve this by elemination
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]

Solve the equation 3x + 5y = 16 for y,
Answer:
y=16-3x/5
Step-by-step explanation:
I'm adding a pic of my solution. i hope you find it helpful.
The solution to the equation 3x + 5y = 16 for y is y = (16 - 3x) / 5. This is achieved by isolating y on one side of the equation.
Explanation:To solve the equation 3x + 5y = 16 for y, you first need to isolate y on one side of the equation. This can be done in the following steps:
Subtract 3x from both sides of the equation, which gives you 5y = 16 - 3x.Next, divide every term of the equation by 5 to solve for y, which gives you y = (16 - 3x)/5.So, the solution for y in terms of x is y = (16 - 3x)/5.
