A dog runs 100 yards from one corner of a rectangular park to the opposite corner. If the length of the park is 28 yards, what is the width?
9514 1404 393
Answer:
96 yards
Step-by-step explanation:
The diagonal through the park cuts the rectangle into two right triangles. The Pythagorean theorem tells you the relationship between the sides of a right triangle and its hypotenuse: the sum of the squares of the sides is equal to the square of the hypotenuse.
The diagonal is the hypotenuse, so we have ...
100² = 28² + w²
w = √(10000 -784) = 96
The width of the park is 96 yards.

Additional comment
The integer side lengths of a right triangle form what is called a "Pythagorean triple." One of the most often seen of these is (3, 4, 5). Other commonly seen Pythagorean triples are (5, 12, 13), (7, 24, 25), (8, 15, 17).
You may notice that the numbers here are those of the (7, 24, 25) Pythagorean triple, multiplied by 4. If you recognize the given lengths as having the ratio 28:100 = 7:25, you have the clue you need to determine the answer simply from your knowledge of Pythagorean triples.

STEP1
Equation at the end of step 1
(6x + 3) • ((3x2 + 8x) + 5)
STEP2
STEP3
Pulling out like terms
3.1 Pull out like factors :
6x + 3 = 3 • (2x + 1)
Trying to factor by splitting the middle term
3.2 Factoring 3x2 + 8x + 5
The first term is, 3x2 its coefficient is 3 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 3 • 5 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5
3x2 + 3x + 5x + 5
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x+1)
Add up the last 2 terms, pulling out common factors :
5 • (x+1)
Step-5 : Add up the four terms of step 4 :
(3x+5) • (x+1)
Which is the desired factorization

What is the value of the expression f(-3) + 2f(-1) - f (4)
PLEASE HELP NO LINKS
Answer:
22
Step-by-step explanation:
Find f(-3) :
f(x) = x² + 2x for x ≤ -3
That means for those values of x, less than or equal to -3, this is the function.
So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3
Now, f(-1) :
From the given data, we see it is: f(x) = 2 [tex](\frac{1}{3} )^{2x}[/tex]
We take this because -1 lies between -3 and 4.
Now, f(-1) = 2 [tex](\frac{1}{3} )^{2(-1)}[/tex]
=> [tex]f = (-1) = 2(3)^{2} = 2 (9) = 18[/tex]
For f(4) :
Clearly, the function is: [tex]f (x) = \frac{2x - 5}{x-7}[/tex]
[tex]f (4) = \frac{2(4)-5}{4-7} = \frac{3}{-3} = -1[/tex]
Therefore, f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22.

What is the definition of mathematic
Answer:
Mathematics :Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.
Since the beginning of recorded history, mathematic discovery has been at the forefront of every civilized society, and in use in even the most primitive of cultures. The needs of math arose based on the wants of society. The more complex a society, the more complex the mathematical needs. Primitive tribes needed little more than the ability to count, but also relied on math to calculate the position of the sun and the physics of hunting.

The admission fee at a small fair is $2.00 for children and $4.00 for adults on a certain day 30 people enter the fair and $100 is collected collected how many children and how many adults attended and justify higher and how you know your response make sure to label your variables and state your solution in a complete sentence
Answer:
20 adults and 10 children
Step-by-step explanation:
We need to find the total amount of adults and children for 30 total people (adults + children) and only 100$ for them. 30 adults is 120$. We need to take off double the amount of money that would bring it to 100$ because the cost for each child is half of an adult. That way, we have 80$ of adults, and when we fill in the rest with children, we get to 100$ total and 30 total people.
Answer:
10 children 20 adults
Step-by-step explanation:
children = c
adult = 2c (double than children)
2(c) + 4(2c) = 100
10c = 100
c = 10 10 children
30-10 = 20 20 adults
$2(10) = $20
$4(20) = $80
$20+$80 = $100

Step-by-step explanation:
Adding the two equations, we have ...
(d +e) +(-d +e) = (12) +(-8)
2e = 4
e = 2 . . . . . . matches choice C
(d, e) = (10, 2)
Answer:
The ordered pair as (d, e) is (10, 2).Step-by-step explanation:
Given that:
d + e = 12 ______(i) - d + e = - 8 ______(ii)To Label:
The ordered pair as (d, e).Adding equation (i) and (ii).
⟶ d + e + (- d + e) = 12 + (- 8)
⟶ d + e + - d + e = 12 - 8
Cancelling d.
⟶ 2e = 4
⟶ 2e = 2 × 2
Cancelling 2.
⟶ e = 2
In equation (i)
⟶ d + e = 12
Putting the value of e.
⟶ d + 2 = 12
⟶ d = 12 - 2
⟶ d = 10
Hence,
The ordered pair as (d, e) = (10, 2)250 grams of sugar cost 150 dollars at Shop X. 100 grams of sugar cost 95 dollars at Shop Y. What is the difference in cost per kilogramme?
350 dollars
Step-by-step explanation:(step 1) Find the cost per kilogramme of sugar in shop X
In shop X:
250 grams of sugar costs 150 dollars.
Remember that;
1000 grams = 1 kilogramme.
=> 250 grams will be equal to 0.25 kilogramme
Therefore (replacing 250 grams with 0.25 kilogramme) in shop X;
0.25 kilogramme of sugar costs 150 dollars
Now, if
0.25 kilogramme = 150 dollars,
=> 1 kilogramme = 150 dollars x 1 kilogramme / 0.25 kilogramme
=> 1 kilogramme = 600 dollars
Therefore, the cost per kilogramme of sugar in shop X is 600 dollars
(step 2) Find the cost per kilogramme of sugar in shop Y
In shop Y:
100 grams of sugar costs 95 dollars.
Remember that;
1000 grams = 1 kilogramme.
=> 100 grams will be equal to 0.1 kilogramme
Therefore (replacing 100 grams with 0.1 kilogramme) in shop Y;
0.1 kilogramme of sugar costs 95 dollars
Now, if
0.1 kilogramme = 95 dollars,
=> 1 kilogramme = 95 dollars x 1 kilogramme / 0.1 kilogramme
=> 1 kilogramme = 950 dollars
Therefore, the cost per kilogramme of sugar in shop Y is 950 dollars
(step 3) Find the difference in cost per kilogramme of sugar between the two shops
The difference is calculated by subtracting the cost per kilogramme of sugar in shop X from the cost per kilogramme of sugar in shop Y. i.e
=> cost per kilogramme of sugar in shop Y - cost per kilogramme of sugar in shop X
=> 950 dollars - 600 dollars
=> 350 dollars.
Therefore, the difference in cost per kilogramme is 350 dollars

1/2b-7=5.5 slove for b
Answer:
b = 25
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] b - 7 = 5.5 ( multiply through by 2 to clear the fraction )
b - 14 = 11 ( add 14 to both sides )
b = 25
Answer:
B=25
Explanation1
1/2b−7=5.5
Add 7 to both sides.
1/2b=5.5+7
b=5.5+7
Add 5.5 and 7 to get 12.5.
1/2 b=12.5
Multiply both sides by 2, the reciprocal of 1/2.
b=12.5×2
Multiply 12.5 and 2 to get 25.
b=25

The value of x = z = 73 degrees and y = 107degrees
3) Geometry is a branch of mathematics that deals with the measurement of lines and angles.
From the diagram shown, we can see that the two lines intersect at a point. The following is therefore true:
y = 107° (vertically opposite angle)The sum of z and 107 is supplementary. Hence;
z + 107 = 180z = 180 - 107z = 73degreesAlso, the sum of x and y is also supplementary. This shows that:
x + y = 180x + 107 = 180x = 180 - 107x = 73dgreesFrom the calculations, hence x = z = 73 degrees and y = 107degrees
