Layla is walking in a rectangular park. She walks one side that is 50 yards and then the other
side that is 120 yards. Layla develops a cramp in her leg and walks diagonally through the park
to head back home. What is the total distance that layla walked? (HINT: Final answer is
perimeter of the triangle park)
120 yd.
PARK
PARK
50 vd
Oak St
1
Park Rd
Total distance walked by Layla is 300 yards
Solution:
Given that,
Layla is walking in a rectangular park
She walks one side that is 50 yards and then the other side that is 120 yards
Length = 120 yards
Width = 50 yards
Layla develops a cramp in her leg and walks diagonally through the park to head back home
Let us find the length of diagonal of rectangle
[tex]d=\sqrt{w^2+l^2}[/tex]
[tex]d = \sqrt{50^2+120^2}\\\\d = \sqrt{2500+14400}\\\\d = \sqrt{16900}\\\\d = 130[/tex]
Thus length of diagonal is 130 yards
What is the total distance that layla walked?
Given that Final answer is perimeter of the triangle park
The diagonal and length and width forms a right angle triangle
Perimeter of triangle = diagonal length + width + length
Perimeter of triangle = 130 + 50 + 120 = 300
Thus total distance walked by Layla is 300 yards
The total distance Layla walked, including the two sides of the park and the diagonal path, is calculated using the Pythagorean theorem to be 300 yards.
Explanation:The question asks us to find the total distance Layla walked while going through the rectangular park diagonally. Layla first walks one side of the park which is 50 yards long and then the adjoining side which is 120 yards long. To do this, we will first find the length of the diagonal using the Pythagorean theorem and then add it to the sum of the two sides she walked to get the total distance. The Pythagorean theorem states that in a right-angled triangle the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written as c2 = a2 + b2.
Applying the Pythagorean theorem to find the diagonal (hypotenuse):
Let a = 50 yards (length of the first side)Let b = 120 yards (length of the second side)c2 = a2 + b2 = 502 + 1202c2 = 2500 + 14400c2 = 16900c = √16900 = 130 yards (length of the diagonal)Now, we can find the total distance Layla walked:
Distance along the first side = 50 yardsDistance along the second side = 120 yardsDistance diagonally across the park = 130 yardsTotal distance = 50 yards + 120 yards + 130 yardsTotal distance = 300 yardsTherefore, the total distance Layla walked is 300 yards.

write an algebraic expression for the following: the product of 5 and the sum of 9 and y. if y = 3 what’s the value of the expression
Answer:
60
Step-by-step explanation:
5 x (9 + y)
= 5 x ( 9 + 3)
= 5 x (12)
=60
Final answer:
The algebraic expression is 5(9 + y), which becomes 5(12) when y equals 3, resulting in a value of 60.
Explanation:
The algebraic expression for the product of 5 and the sum of 9 and y is 5(9 + y). To find the value of this expression when y equals 3, you substitute 3 for y in the expression, getting 5(9 + 3). Following the order of operations, calculate the sum inside the parentheses first, which gives you 5(12), and then multiply by 5 to find the product, resulting in a final value of 60.

What is the first step for evaluating this expression?
Substitute 3 for X
distribute the 3
combine like terms
Answer:
11
3Step-by-step explanation:
Given
3(x - 1)² + 2x - 7 ← substitute x = 3 into the expression
= 3(3 - 1)² + 2(3) - 7
= 3(2)² + 6 - 7
= 3(4) - 1
= 12 - 1
= 11
The first step in evaluating the expression is to substitute 3 for x.
The first step in evaluating the expression 3(x-1)^2 + 2x - 7 for x=3 is to substitute 3 for x. This is because before you can simplify or combine like terms, you need to know the value of the variables involved. Once substitution is done, you can proceed with further simplification such as distributing and combining like terms.

Answer:
104
Step-by-step explanation:
Any expression multiplied by 0 equals 0
when adding or subtracting 0, the quantity doesn't change
Answer:
I think it is 4 or 104. There are 2 ways to look at it.
Way #1:
50 + 50 = 100
100 - 25 = 75
75 x 0 = 0
2 + 2 = 4
0 + 4 = 4
Way #2:
50 + 50 = 100
25 x 0 = 0
100 - 0= 100
2 + 2 = 4
100 + 4 = 104
9. Abby walked 3 km west. Then she walked
twice as far going east. She continued east
for another kilometre, stopping 2 km east
of Lauren's home. When Abby started
walking, how far was she from Lauren's
home? Explain how you know.
Answer:
2km
Step-by-step explanation:
- Abby walked 3 km west: Abby is 3km west from her starting point.
- Then she walked twice as far going east: she walks 6km east so she's 3 km east from her starting point
- She continued east for another kilometre: She's is 4 km east from her starting point
- Stopping 2 km east of Lauren's home: She's currently 2 km east from Lauren's home and 4km east from her starting point. Therefore, Abby's starting point is 4km - 2km = 2km west from Lauren's home

Which term completes the product so that it is the difference of squares?
| (-5x-3)(-5x+_
.
..
со со
Answer:
3
(-5x - 3)(-5x + 3)
Step-by-step explanation:
Difference of squares is a special type of factoring when you are subtracting two numbers that are perfect squares. Perfect squares are numbers that, when you find its square root, it is a whole number.
Difference of squares follows this rule:
a² - b² = (√a² - √b²)(√a² + √b²) = (a - b)(a + b)
Notice in the factored form, you take the same number in both brackets. In one set of brackets you add the numbers. In the other brackets, you subtract the numbers.
In (-5x - 3)(-5x + __), the blank in the second bracket will use the same number as the second number in the first brackets.

9:3 :: 49 :
To solve this ratio problem, we need to determine the relationship between the given numbers and apply it to find the answer.
Explanation:The given expression is:
9:3 :: 49 :
To solve this, we need to determine the relationship between 9 and 3, and then apply the same relationship to 49.
The symbol '::' represents the ratio or proportion between the numbers before and after it.
9 divided by 3 is equal to 3, so the relationship here is that the first number is three times the second number.
Now, let's apply the same relationship to 49:
49 divided by 3 is equal to 16.33, so we can say that the answer is 16.33.

The final answer is 9 : 3 :: 49 : 16.33.
Here's a step-by-step solution:
We need to find the missing number such that the ratios are equivalent. This can be written as a proportion: 9/3 = 49/x.First, simplify the left side: 9/3 = 3.So, we have: 3 = 49/x.Next, solve for x by multiplying both sides by x: 3x = 49.Finally, divide both sides by 3 to isolate x: x = 49/3.Therefore, x = 16.33 (rounded to two decimal places).The answer to the question is therefore 49 : 16.33.

Koby's solution for 4(x - 3) = x + 2 is shown at the
right. Did he solve the equation correctly? Explain why
or why not.
4(x - 3) = 3x +2
4x - 12 = 1/x + 2
2. (4X – 12) = 2 · ( 3x + 2
8x - 12 = x + 2
8x = x + 14
7x = 14
x
=2
Koby did not solve the equation correctly. The correct solution for 4(x - 3) = x + 2 is x = 14/3 or approximately 4.667. The steps include distribution, combining like terms, and isolating the variable.
The student's solution contains errors in the algebraic process. The correct steps to solve the original equation 4(x - 3) = x + 2 are as follows:
Distribute the 4 into the parentheses: 4x - 12 = x + 2.
Subtract x from both sides to get all the x terms on one side: 4x - x - 12 = 2.
Simplify the equation: 3x - 12 = 2.
Add 12 to both sides to isolate the variable term: 3x = 14.
Divide both sides by 3 to solve for x: x = 14/3.
The correct solution is x = 14/3 or approximately 4.667, not x = 2 as Koby had. To check the solution, you substitute the value back into the original equation:
4(14/3 - 3) = 14/3 + 2
which simplifies to:
56/3 - 12 = 14/3 + 2
and further to:
56/3 - 36/3 = 14/3 + 6/3
resulting in an identity:
20/3 = 20/3.
