An equilateral triangle has a perimeter of 15x3 33x5 feet. what is the length of each side? x3 feet 5 11x2 feet 5x2 11 feet 5x3 11x5 feet
The length of each side of the equilateral triangle is 5x³ + 11x⁵
Calculating PerimeterFrom the question, we are to determine the length of each side of the equilateral triangle.
An equilateral triangle has its sides equal to each other.
If the length of a side of an equilateral triangle is c,
Then, the perimeter, P, of the triangle is
P = 3c
From the given information,
P = 15x³ + 33x⁵
∴ 3c = 15x³ + 33x⁵
c = (15x³ + 33x⁵) / 3
c = 3(5x³ + 11x⁵) / 3
c = 5x³ + 11x⁵
Hence, the length of each side of the equilateral triangle is 5x³ + 11x⁵

Answer:
t =amount of texts
a. 0.01t+20=y
b. 50=y
so that means that they equal each other
0.01t+20=50
-20
0.01t=30
t=3001
Hope This Helps!!!
Answer:
For plan B to save money cell phone user need to send 3000 texts per month as [tex]\frac{x}{y}[/tex] expresses the average texts sent per month by cell phone user and its obtained value is 3000.
Step-by-step explanation:
In the question it is given that a cell phone company offers two plans for minutes.
Plan A: $20 per month and $1 for every one hundred texts.
Plan B: $50 per month with free unlimited texts.
It is required to find that how many texts would be needed to send per month for plan B to save money. be needed to send per month for plan B to save money.
Step 1 of 5
In Plan A $20 per month and $1 for every one hundred texts are costed so the cost of Plan A is given by following equation,
[tex]$A=20 y+\frac{x}{100}$[/tex]
In Plan B $50 per month with free unlimited texts are costed so the cost of Plan B is given by following equation,
[tex]$$B=50 y$$[/tex]
Step 2 of 5
Now comparing the obtained equations [tex]$A=20 y+\frac{x}{100}$[/tex]
and B=50y.
[tex]$20 y+\frac{x}{100}=50 y$$[/tex]
Step 3 of 5
Subtract 20y from both the sides of the obtained equation [tex]$20 y+\frac{x}{100}=50 y$[/tex] and simplify using subtraction properties.
[tex]$$\begin{aligned}&20 y+\frac{x}{100}-20 y=50 y-20 y \\&\frac{x}{100}=30 y\end{aligned}$$[/tex]
Step 4 of 5
Multiply both the sides of the obtained equation [tex]$\frac{x}{100}=30 y$[/tex] by 100 and simplify using multiplication properties.
[tex]$$\begin{aligned}&\frac{x}{100} \cdot 100=30 y .100 \\&x=3000 y\end{aligned}$$[/tex]
Step 5 of 5
Divide both the sides of the obtained equation x=3000y by y and simplify using division properties.
[tex]$$\begin{aligned}&\frac{x}{y}=\frac{3000 y}{y} \\&\frac{x}{y}=3000\end{aligned}$$[/tex]
As [tex]$\frac{x}{y}$[/tex] expresses the average texts sent per month by cell phone user. So, for plan B to save money cell phone user need to send 3000 texts per month.

In a 3-digit number, the middle digit is 3 times the last digit and 4 more than the first digit. All the digits are odd and can only be used once. What is the 1st number?
Answer:
5
Step-by-step explanation:
This is quite some trial and error question.
Based on the question, the numbers we can use are 1,3,5,7 and 9.
We will start with the middle digit first.
Since the question has stated it is 3 times the last digit, the number has to be in multiples of 3.
So we are left with: 3 and 9.
Then, the question also states the middle digit is 4 more than the first digit. See, its a digit, so the value cannot be less than 1 (odd numbers only and no negative values), so if we subtract 4 to the middle digit to find the first, it should still be a Positive Single numerical value.
3 - 4 = -1
9 - 4 = 5
Therefore, this middle digit is = 9.
Since we know the middle digit = 9
The first digit will be 9 - 4 = 5
The whole value is now 593.

Six less than the quotient of two and W
Six less than the quotient of two and a number "W"
Let's take this step-by-step. First, change the written-out numbers to numerals:
6 less than the quotient of 2 and a number "W"
Next, combine the smallest part. In this case, it would be:
the quotient of 2 and a number "W"
Here, you are finding the quotient of a specific part: 2 and W. When we have specific sections like this in math, we put parentheses around them, like this:
6 less than the quotient of (2 and a number "W")
Now we need to remember what a "quotient" is. This means that there is division between the two numbers mentioned - in this case, 2 and the number W. But which is being divided into which? The number 2 comes first, so we think of 2 as being the first number used. Therefore, we are looking at:
6 less than (2 divided by W)
Division problems are exactly the same as fractions. For example, 3 divided by 1 is the same as 3 ÷ 1, which is also the same as 3/1 (which equals 3). In our case, 2 divided by W is the same as 2/W (your teacher might want this written as 2 ÷ W, but they mean the same thing). Now, we can write the equation as:
6 less than (2/W)
Which can also be written as:
6 less than 2 ÷ W
To finish this up, let's take a step back for a moment Imagine you have 10 jelly beans, and you eat 7 of them. You now have 7 less than 10, or 3 jelly beans. This can also be written as 10-7 = 3.
In our example, we have 6 less than (2/W). If we use the jelly bean equation we found as a starting point, we can change the 7 to 6 and the 10 to (2/W). Then, we get this:
(2/W) - 6
Which can also be written as:
2 ÷ W - 6
And that's your answer! Both of those mean the same thing so they're both correct. Your teacher might prefer you write it one way or the other, though. If this is the case, make sure to choose the solution that best fits your teacher's request.

Step-by-step explanation:
When computing a consecutive sum of integers with a difference of 1.
Use gauss's formula of (n/2)(first number + last number).
with n being the # of integers.
Since it is ascending and descending, it can be broken down into 2 sequences:
1 + 2 + 3 + ... + 99 and 1 + 2 + 3 + ... + 100.
Once each is calculated, add them up to find the value.
So:
1 + 2 + 3 + ... + 99 = (99/2)(100) = 4950.
1 + 2 + 3 + ... + 100 = (100/2)(101) = 5050.
4950 + 5050 = 10000

We can do the inverse, where division basically becomes multiplication. You just flip the denominator and numerator (lower and upper part of the division sign).
[tex]\frac{2}{3} *-\frac{5}{2}[/tex]
The negative stays even when you inverse it. Make sure on future problems you inverse whats being divided, which in this case was -2/5.
We can now multiply across and get:
[tex]- \frac{10}{6}[/tex] as 2•5=10, 3•-2=-6. Therefore -10/6.
Which can be simplified into [tex]-1 \frac{2}{3}[/tex]. This is because 10 goes into 6 once leaving 4. That makes it -1 4/6, but 4/6 can be reduced by a common factor, 2. So just divide 4 and 6 by 2, which is 2/3. So thats why it is -1 2/3.

Completed interview, C = 432
Refusal by the Respondent, R = 586
No answer/ not at home , N = 902.
Non - working Numbers, NW = 80.
From the above data, we got responses from completed interviews and refusals by respondents.
so responded number (RN) is
RN=C+R
RN= 432+ 586
RN= 1018.
The actual number of samples =Total samples - non-working samples Actual number of samples=2000-80
The actual number of samples=1920
And the response rate (RR) is
