The perimeter of an equilateral triangle is 11 inches more than the perimeter of a square, and the side of the triangle is 6 inches longer than the side of the square. find the side of the triangle.
Answer:
13 inches
Step-by-step explanation:
Let P(t) and P(s) be the perimeters of the equilateral triangle and square respectively. Similarly, t and s be the side lengths of equilateral triangle and square respectively.
According to the first condition :
(Perimeter of an equilateral triangle is 11 inches more than the perimeter of a square)
[tex] \implies P(t) = P(s) + 11[/tex]
[tex] \implies 3t = 4s + 11....(1)[/tex]
According to the second condition :
(The side of the triangle is 6 inches longer than the side of the square)
[tex] \implies t = s + 6....(2)[/tex]
From equations (1) & (2)
3(s + 6) = 4s + 11
3s + 18 = 4s + 11
3s - 4s = 11 - 18
-s = - 7
s = 7 inches
[tex] \because t = s + 6[/tex]
[tex] \because t = 7 + 6[/tex]
[tex] \because t = 13\: inches[/tex]
Thus the side of the triangle is 13 inches long.

John, Bill, and George are all in a field throwing a football. The three of them form a triangle and throw to pass to each other. Bill notices that he is 22 feet from John and 27 feet from George. He then sees that the uses his arms to find the angle formed between John and Georges position from where he is, it is 60 degrees. What is the distance between John and George rounded to the nearest foot?
Answer:
25 feet
Step-by-step explanation:
I have created a visual so its easier to make an equation
Because we are given two sides and its gamma we are going to need to solve for the missing side length using law of cosines
the formula for law of cosines is
[tex]c = \sqrt{a^2+b^2-2ab*cosy}[/tex]
where a and b = side lengths
c= missing side length and y = gamma
with the given information all we have to do is plug in the values
[tex]c=\sqrt{22^2+27^2-(22)(27)cos(60)} \\22^2=484\\27^2=749\\729+484=1213\\\\2*22*27=1188\\1188*cos(60)=594\\1188-594=619\\\sqrt{619} =24.87971016[/tex]
Finally we round to the nearest foot 25
so we can conclude that the distance between john and george is 25 feet

224 in 8 minutes. Use the unit rate to complete the table of values for the proportional relationship.
X. Y
2. ?
4. ?
6. ?
9514 1404 393
Answer:
see attached
Step-by-step explanation:
It can be convenient to use mental arithmetic methods* to fill in this table.
Since the relationship is proportional the y-value for x=4 will be half that for x=8, so will be 224/2 = 112. Similarly, the y-value for x=2 will be half that for x=4, so will be 112/2 = 56.
Then the y-value for x=6 will be the sum of the y-values for x=2 and x=4, so will be 112 +56 = 168.
If you actually care to find the "unit rate," you can divide the y-value for x=2 by 2 to get the corresponding y-value for x=1: 56/2 = 28. The unit rate is 28.
_____
* Multiplication or division by 2 is simply a matter of doubling or halving. In most cases, it is easy to double a number, or to compute half of it. (If it isn't, you need to review your arithmetic facts.)
The price of a suit decreased from $280 to $182 during a clearance sale.
What is the percent of decrease in the price?
Answer:
12%
Step-by-step explanation:
Answer:
%35
Step-by-step explanation:
You would take 182 and divide it by 280. That equals .65, you would take the 1 and subtract your answer to get .35 or %35.

x2 - 2x + 2 = 0
solve each equation by graphing. if integral roots cannot be found estimate the roots by stating the consecutive integers between which the Roots lie.
Answer:
Step-by-step explanation:
Let's solve x^2 - 2x + 2 = 0 using "completing the square:"
1. Take the coefficient of x: It is -2.
2. Halve this, obtaining -1.
3. Square this result, obtaining 1.
4. Add 1, and then subtract 1, between -2x + 2:
x^2 - 2x + 1 - 1 + 2 = 0
5. Rewrite x^2 - 2x + 1 + 1 = 0 beginning with the square of a binomial
(x - 1)^2 + 1 = 0, or (x - 1)^2 = -1
6. Take the square root of both sides, obtaining x - 1 = ±i, or x = 1 ±i
7. Write out the roots: they are x = 1 + i and x = 1 - i (two complex, different roots). No real roots, so the last command of this question is irrelevant. The graph never touches the x-axis; the graph is in Quadrants I and II and is that of a parabola that opens up.

Carlos Measured the link of a book to be 21 cm the actual length of a book is 23cm which of these is closest to the percent error for Diego's measurements
Answer: 8.70%
Step-by-step explanation:
Percent error is calculated as:
= (Accepted value - Experimental value) / Accepted value × 100
= (23 - 21) / 23 × 100
= 2/23 × 100
= 8.70%
The percentage error is 8.70%

What is P(not prime)?
Write your answer as a percentage.
==========================================================
Explanation:
The primes in this list are: {2,3,5}
The value 1 is not prime.
We have 3 primes out of 5 values total, so 3/5 = 0.6 = 60% of the list is prime. That makes 100% - 60% = 40% of values are not prime
This is the probability of getting a non-prime number.
Answer:
40%
Step-by-step explanation:
Prime numbers are whole numbers greater than 1 that only have 2 factors, for example, 2, 3, 5, 7, 11 are all prime numbers
In this data set 2, 3, and 5 are all prime numbers
3 out 5 numbers are prime
so the fraction is [tex]\frac{3}{5}[/tex]
after you have found the fraction, you can divide it to find the percentage
In this case, when you divide the fraction you get 0.6
to make this a percentage you move the decimal place two spaces to the right. so 60%
60% are the values that are prime so you do this equation
100%-60%=40%
