Answers
36=(0.12)n
n=300
300 students were surveyed.
That's the way I answer in my country but I'm not sure about this solution is correct in your school or not.
Answer:
300 students were surveyed.
Step-by-step explanation:
We are given the following information in the question:
Percentage of students at Rockwood Junior High School who speak Spanish = 12%
Number of students at Rockwood Junior High School who speak Spanish = 36
We have to find the total number of students who surveyed:
Formula:
Let x be the total number of students who were surveyed.
[tex]12\% \text{ of }x = 36\\\\\displaystyle\frac{12}{100}\times x = 36\\\\x = \frac{36\times 100}{12}\\\\x = 300[/tex]
Thus, 300 students were surveyed.

__________________________________________
Explanation:
__________________________________________
Write the expression; which is an equation, as follows:
__________________________________________
" 4x − 12 = 2(-x) " ; in which "x" represents "the number for which we shall solve" .
___________________________________________
Note:
If the "number" = "x" ; the "opposite of the number" = " -x " ;
___________________________________________
Rewrite as: " 4x − 12 = -2x " ;
_____________________________________________
→ Add "12" ; & add "2x" ; to EACH SIDE of the equation:
4x − 12 + 12 + 2x = -2x + 12 + 2x ;
to get: 6x = 12 ;
____________________________________________________
Now, divide each side of the equation by "6" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
____________________________________________________
6x / 6 = 12 / 6 ;
to get: x = 2 .
____________________________________________________
Answer: The number is: "2 " .
____________________________________________________
Let us check our answer, by plugging in "2" for "x" in our original equation:
_____________________________________________________
→ " 4x − 12 = 2(-x) " ;
Let us plug in "2" for "x" ; to see if the equation holds true; that is; if both side of the equation are equal; when "x = 2" ;
→ " 4(2) − 12 = ? 2(-2) ??
→ 8 − 12 = ? -4 ? ;
→ -4 = ? -4 ?? Yes!

What represents the number written as 23 and 37 thousandths
Answers
The number written as 23 and 37 thousandths can be expressed in decimal form as 23.037.
What is Place value?The foundation of our whole number system is place value. In this approach, the value of a digit in a number is determined by where it appears in the number.
When we write a number like 23.037, each digit to the left of the decimal point represents a different place value. The place values start from the right with ones, then increase by a factor of 10 as we move to the left.
So in the number 23.037:
The digit 7 is in the thousandth place, meaning it represents 7/1000 or 0.007.
The digit 3 is in the hundredth place, meaning it represents 3/100 or 0.03.
The digit 0 is in the tenth place, meaning it represents 0/10 or 0.
The digit 2 is in the one's place, meaning it represents 2 ones, or simply 2.
Therefore, 23.037 can be written as:
23 + 0.037
or
23 and 37 thousandths

Joe's age x, is 5 times his age 10 years ago. Which equation represents the statement?
a) x = 5x - 6
b) x = 5x + 6
c) x= 5 - 10x
d) x = 5(x - 10)
Answers
Answer:
d) X=5(X-10)
Step-by-step explanation:
Joe's age is change to X, so we know that his age today is 5 times his age 10 years ago.
His age ten years ago is X-10, if for example he is 25 today then his age ten years ago would be 15 (25-10).
If his age now is 5 times his age 10 years ago we will have to multiply his age ten years ago to get his age today.
Example:
5(X-10), this is how we can write 5 times his age 10 years ago, in a mathematical way.
Now we just have to know that this equation is equal to his age today X.
5(X-10) = X, or another way to put it is:
X=5(X-10)
When filing separately, both Melvin and Sylvia have a standard deduction of $5700, and each can claim him/herself as an exemption for $3650. Neither has any additional adjustments to income. What is Melvin's taxable income? How about Sylvia's taxable income?
Answers
Melvin and Sylvia's taxable income is calculated by subtracting the sum of the standard deduction ($5,700) and the personal exemption ($3,650) from their adjusted gross income. Since the adjusted gross income was not provided, the exact taxable income cannot be determined without that information.
Explanation:When calculating Melvin and Sylvia's taxable income, we first need to use the given standard deduction and personal exemption to determine their taxable income. According to the information, the standard deduction is $5700 and the personal exemption is $3650 Therefore, we subtract the sum of these deductions from their adjusted gross income to find their taxable income.
Assuming Melvin and Sylvia both have the same adjusted gross income and ignoring any typos or irrelevant parts of the questions being asked, we have:
The formula for each individual's taxable income is as follows:
taxable income = adjusted gross income - (standard deduction + personal exemption)
To find Melvin or Sylvia's taxable income, simply plug their adjusted gross income into the formula.

Answers
P = 292
L = 5W - 4
292 = 2(5W - 4 + W)
292 = 2(6W - 4)
292 = 12W - 8
292 + 8 = 12W
300 = 12W
300/12 = W
25 = W <=== width is 25 ft
L = 5W - 4
L = 5(25) - 4
L = 125 - 4
L = 121 <=== length is 121 ft

Use the table to write and solve an equation to tell you the number of minutes for which the cost of both phone companies is equal
Answers
company B : 0.06m
to find out when they are equal, set them equal to each other and solve for m, the number of minutes
0.36 + 0.03m = 0.06m
0.36 = 0.06m - 0.03m
0.36 = 0.03m
0.36 / 0.03 = m
12 minutes <=== they will be the same at 12 minutes
check...
company A : 0.36 + 0.03(12) = 0.72
company B : 0.06(12) = 0.72
correct
Answer:
For 12 minutes, the cost of both companies will be equal and the cost will be 72¢.
Step-by-step explanation:
We are given the following information:
Let x be the number of minutes where the cost of both companies is equal.
Company A charger = 36 cents and 3 cents per minute
Company B charges = 6 cents per minute
Cost of Company A after x minutes:
[tex]36 + 3x[/tex]
Cost of company B after x minutes:
[tex]6x[/tex]
Equating the two equations:
[tex]36 + 3x = 6x\\6x-3x =36\\3x =36\\x=12[/tex]
Thus, for 12 minutes, the cost of both companies will be equal and the cost will be 72¢.
What is the debt-to-credit ratio of the Handy Hardware Credit Card?

EX: $1500+$1000+$500=$3000
step 2: add the amount of your creedit lines on your cards
EX: $6000+$3500+$2500=$12000
step 3: divide your total debt by your total credit
EX: $3000/$12000=25% or 0.25
Answer:
Debit to credit ratio is the ratio of amount of credit you are using divided by the total amount of credit you are eligible to use.
Step-by-step explanation:
Consider that you have a credit card issued to you by bank. Now its credit limit is $10,000. Up to now, you have spent $4000, your debit to credit ratio will become:
= (4000/10000)*100
= 40%
Now credit is the amount of money, equivalent to which, goods can be purchased with promise of future payments.
whereas, Debt is the money which is obligated to pay before services or goods are used.
So, debt to credit ratio is one of the important factors when banks issue credit cards of certain limits to their customers.
the function y = 3.75 + 1.5(x-1) can be used to determine the cost in dollars for a taxi ride of x miles. what is the rate of change of the cost in dollars with respect to the number of miles?
Answers
Answer:
rate of change of the cost in dollars with respect to the number of miles= 1.5
Step-by-step explanation:
We have been given the function y = 3.75 + 1.5(x-1)
Let us simplify this equation
y = 3.75 + 1.5(x-1)
y= 3.75+1.5x-1.5
y = 1.5x+2.25
On comparing this equation withe the slope intercept form y = mx + b, we get
m = 1.5
b = 2.25
here x represents distance in miles and y represents the cost in dollars. So, the rate of change of the cost in dollars with respect to the number of miles would be equal to the slope of the line.
Thus, we have
rate of change of the cost in dollars with respect to the number of miles
= slope
= 1.5
The rate of change of a function is the slope of the function.
The rate of change of the function is $1.5 per miles
The function is given as:
[tex]\mathbf{y= 3.75 + 1.5(x - 1)}[/tex]
Open bracket
[tex]\mathbf{y = 3.75 + 1.5x - 1.5}[/tex]
Collect like terms
[tex]\mathbf{y = 1.5x - 1.5 + 3.75}[/tex]
[tex]\mathbf{y = 1.5x +2.25}[/tex]
A linear equation is represented as:
[tex]\mathbf{y = mx +b}[/tex]
Where: m represents the slope
So, by comparison:
[tex]\mathbf{m =1.5}[/tex]
Hence, the rate of change of the function is $1.5 per miles

A triangle has an area of 10.5 square feet. The base of the triangle is 6 feet. What is the height?
Answers
Let's put what we know in an equation. We know that B X H / 2 = the area of a triangle.
6 X H (height) / 2 = 10.5 Sq. Ft.
If you want to find the height, let's solve for H. I think we should combine 6 and H together, and that would simplify to 6h / 2 = 10.5.
Now to get 6h by itself, let's multiply by 2 to each side. It would then look like: 6h = 21. To finally get "h" by itself, we need to divide h by 6 to each sides. After you do that, the answer simplified is: h = 3.5.
To make sure my answer is correct, let's plug in the height with the base, if it equals 10.5.
6 X 3.5 / 2 = 10.5
(6 X 3.5 ) / 2 = 10.5
(21) / 2 = 10.5
10.5 = 10.5
My answer is correct, since each side equals the same. Hope this isn't too confusing, hope this helps! =)

What is the equation of this graphed line?
Answers
y= 6x+7
I think this is it.
y = mx + b
...where b represents the y-intercept and m represents the slope
In this problem, the y-intercept is 7 because you can see that the line intersects the y-axis at the coordinate (0, 7).
The slope is negative because the line is going down when being read from left to right. Two ways you can find the slope of the line is by calculating the rise/run of the line (how many units the line goes up/down by how many units the line goes to the right).
You can also find the slope using the equation :
m = y2 - y1 / x2 - x1
Substitute the coordinates (the order doesn't matter as long as the coordinates correspond).
m = -2 - 7 / 8 - 0
m = -9 / 8
The slope is -9/8.
Combine the information you now know into the line's equation.
Solution: y = - 9/8x + 7

Answers
Now analyze the statements.
Neither function is an even function ---> FALSE because the fact that the function g(x) has vertex (0,2) means that the symmetry axis of the parabole is the y-axis, so you know that g(x) = g(-x) which is the definition of an even function.
Only the function g(x) is an even function ---> TRUE: I already explained you why you can tell that g(x) is even. Now you just mut observe the graph of f(x) to realize that f(x) is not equal to f(-x) which means that it is not even.
Both functions are even functions ---> FALSE as we stated above f(x0 is not even.
Only the function f(x) is an even function ---> FALSE as we stated above.
