Answer:
x is 2 and y is 2✓3
Step-by-step explanation:
this is because of the 30 60 90 theorem
so 1 is n
and x has to be 2n so it is 2
and y is n√3 so it's 2√3
Answer:
x = 2 , y = √3
Step-by-step explanation:
In right angled Δ, the leg against of 30° angle equals half of length of hypotenuse ⇒ x = 2 and y = √(4 - 1) = √3

Answer:
C, 1 1/14
Step-by-step explanation:
You would convert 1/2 to 7/14 and convert 4/7 to 8/14. You can now add them together, and once you do you get 15/14. You can now simplify, giving you your answer of 1 1/14.
Alex placed a classified ad in the local newspaper to sell his used Nissan Sentra. He plans to write a 9 line ad. The newspaper charges $17.50 for the first three lines (total) and then $8.25 for each extra line. How much will Alex pay for the ad?
Answer:
$67 total
Step-by-step explanation:
9-3= 6
6(8.25)= 49.50
49.50+17.50= $67
Answer:
$67.00
Step-by-step explanation
17.50 (first 3 lines) + 8.25 (for each of the 6 lines left)
17.50 + (8.25*6) =
17.50 + 49.50 =

Selena has a piece of ribbon that is 130 inches long. If she wants to make bracelets that are 9 inches long, how many inches of ribbon will be left over?
Answer:14 4/9
Step-by-step explanation:
Arrange the expressions in ascending order of their values when x = -2.
1-x^2/1-2x
x^2-1/1-2x
2x^2+x/2
3x^2+1/2(x-1)
Step-by-step explanation:
Option (1)
[tex]\dfrac{1-x^2}{1-2x}[/tex]
Put x = -2, let the value is y such that,
[tex]y=\dfrac{1-(-2)^2}{1-2(-2)}\\\\=\dfrac{1-4}{1+4}\\\\=-0.6[/tex]
Option (2)
[tex]\dfrac{x^2-1}{1-2x}[/tex]
Put x = -2, let the value is y such that,
[tex]y=\dfrac{(-2)^2-1}{1-2(-2)}\\\\=\dfrac{4-1}{1+4}\\\\=0.6[/tex]
Option 3)
[tex]2x^2+\dfrac{x}{2}[/tex]
Put x=-2 such that,
[tex]y=2(-2)^2+\dfrac{(-2)}{2}\\\\=7[/tex]
Option (4)
[tex]3x^2+\dfrac{1}{2(x-1)}[/tex]
Put x =-2 such that,
[tex]y=3(-2)^2+\dfrac{1}{2((-2)-1)}\\\\=11.83[/tex]
Ascending values : -0.6,0.6,7,11.83
or
[tex]\dfrac{1-x^2}{1-2x}[/tex] < [tex]\dfrac{x^2-1}{1-2x}[/tex] < [tex]2x^2+\dfrac{x}{2}[/tex] < [tex]3x^2+\dfrac{1}{2(x-1)}[/tex]
Travis made a business trip of
195.5 miles. He averaged
53 mph for the first part of the trip and
58 mph for the second part. If the trip took
3.5 hours, how long did he travel at each rate?
Answer:
At 53 mph, he traveled for 1.5 hours
At 58 mph, he traveled for 2 hours
Step-by-step explanation:
Mathematically;
distance = speed * time
let the time for the first part of the trip be x hours and the second part be y hours
Total hours is 3.5
So therefore;
x + y = 3.5 ••••••••(i)
Now let’s work with the rate
53 mph for x hours = 53 * x = 53x miles
58 mph for y hours = 58 * y = 58y miles
Adding both;
53x + 58y = 195.5 miles ••••••••(ii)
We have two equations to solve simultaneously
From i, x = 3.5 - y
insert into ii
53(3.5-y) + 58y = 195.5
185.5 - 53y + 58y = 195.5
5y = 195.5-185.5
5y = 10
y = 10/5
y = 2 hours
x = 3.5 - y
x = 3.5 - 2
x = 1.5 hours

Which of the following terms best describes three points that all lie in a
straight line?
A. Collinear
B. Congruent
C. Midpoint
D.equal
Answer:
A.
Explanation:
Collinear
The required term is "collinear" which best describes three points that all lie in a straight line. which is the correct answer would be an option (A).
What are the collinear points?Collinear points are locations along a straight line that are represented by a collinear. They are always collinear since a straight line may be traced continuously between any two places. A collinear connection can exist between three or more points, but it is not required. The word required is "collinear," which best depicts three locations that are all in a straight line.
Therefore, the required term is "collinear" which best describes three points that all lie in a straight line.
Hence, the correct answer would be option (A).

IX+XC= WHAT IS THE ANSWER
Answer: X googled it
This converts to the number 99
=========================================================
Explanation:
The upper case letter i means the number 1 in roman numerals. The X represents 10. The C represents 100.
I = 1
X = 10
C = 100
When we form something like IX, we have the smaller digit first and then a larger digit next. Whenever this happens, we subtract
IX = 10-1 = 9
Similarly
XC = 100-10 = 90
So we can see that
IX + XC = 9 + 90 = 99
---------------------------
Since XC is larger than IX, we list XC first when it comes to adding
In other words, we need to write IX+XC as XC+IX which collapses to XCIX
Placing XC next to IX without a plus sign implies the plus sign is there. This is effectively how roman numerals work (they are additive)
So,
XCIX = XC+IX = 90+9 = 99
Note how the XC takes care of the tens digit while IX takes care of the units digit.

20. John Navarro is a salesperson in the appliance department at Morris
Appliance, Inc. He is guaranteed a minimum salary of $185 per week, or
5.5 percent of his total sales—whichever is greater. What is his gross pay
for a week in which his total sales were $3,422?
Answer:
$373.21Step-by-step explanation:
Step one:
weekly pay = $185
commission= 5.5% of sales= 0.055
let the sale be x
and his gross pay be represented by y
hence the expression for the total/gross pay is
y=0.055x+185
Step two:
Required is the gross pay y for x=3422
substituting we have
y=0.055*3422+185
y=188.21+185
y=373.21
Hence for a sale of $3,422 made his gross pay is $373.21

Answer:
23.59 - 14.89 = x
x = 8.7
Step-by-step explanation:
To find x, you need to add all of the other sides and subtract it from the perimeter. 5.62 + 5.62 + 3.65 = 14.89.
23.59 - 14.89 = x, so x = 8.7
Answer:
8.7
Step-by-step explanation:
Add all the numbers together (5.62, 5.62, and 3.65) then take away from the result (23.59) to get answer.

Seven out of ten people say they will vote for Mrs. Meekus . If 5,500 people vote,how many are likely to vote for Mrs.Meekus
Answer:
3,850 people are likely to vote for Mrs. Meekus.
Step-by-step explanation:
Given that Mrs. Meekus has a voting intention of 7 out of 10, that is, 70%, in the event that 5,500 people are going to vote in the elections, the voting intention for this candidate would be obtained through the following calculation:
5,500 x 0.70 = X
3,850 = X
Thus, if said voting intention is reproduced, Mrs. Meekus would be voted by 3,850 voters.
