A park is in the shape of a rectangle 300 feet long 50 feet wide Amaya is standing at one corner of the park at point x he then walks in a straight line to the opposite corner at point y how far does he walk rounded to the nearest tenth
Answer:
[tex]304.1\ \text{feet}[/tex]
Step-by-step explanation:
The dimensions of the rectangle are 300 feet long 50 feet wide
The length between [tex]x[/tex] and [tex]y[/tex] will be the length of the diagonal of the rectangle.
Length of the diagonals can be found using the Pythagoras theorem

The length of a rectangular birthday party invitation is 1 inch less than twice its width. The area of the invitation is 15 square inches.
The length of a rectangular birthday party invitation is 9 inch.
The length of a rectangular birthday party invitation is 1 inch less than twice its width.
Area of the invitation 15 square inches.
what is the area of the rectangle?
A=length× width
That is,the area of a rectangle is length times width.
let x be the width rectangle
width = x
length = 2x - 1
[tex]Area= 15 square inches[/tex]
Using these variables, set up the equation for area.
x(2x - 1) = 15
Solve the equation for x.
[tex]2x^{2} - x = 15[/tex]
Subtract 21 on both sides of the equation.
[tex]2x^{2} - x - 15=0[/tex]
Which method we use to factor the polynomial?
FOIL method
Factor using FOIL, if possible.
(2x +5)(x - 5) = 0
Set the factors equal to zero and solve for x.
2x = -5 and x - 5 = 0
x =- 5/2 or x = 5
x =- 2.5 or x=5
Since we cannot accept a negative value for dimensions, we accept the positive value of x:
x = 5
Therefore,
Length = 2(5) - 1
Length = 10-1
Length = 9
Therefore we get the length is 9 inch

The area of a rectangular fence is 500 square feet. If the width of the
fence is 20 feet, then find its length.
Answer
Here the area and the width of the rectangular fence are given. We have to find length of the fence.
( diagram )
The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.
Given that area is 500 square feet and width is 20 feet.
Substituting values in formula,
⇒500=l×20
⇒20/500
= 20/1×20
[ Dividing both sides by 20 ]
⇒l=25 feet
∴ length of rectangular fence is 25 feet.
Hence, the answer is 25.

Miguel has triple David's money, while Lisbeth has ten dollars less than David. The sum of their money totals $95. How much money does David have?
Answer:
Miguel has $63
Lisbeth has $11
David has $21
Step-by-step explanation:
let Miguel share be M
let Lisbeth share be L
let David share be D
from the question, we know that
M=3D
L=D-10.
M+L+D=95
thus,
3D+(D-10)+D= 95
3D+D-10+D= 95
5D-10 = 95
5D= 95+10
5D= 105
D= 105/5
D= 21.
thus,
M = 3D = 3×21
= $63
L = D-10 = 21-10
= $11
(63+21+11)$ = $95

times its birth
weight. How many pounds did the baby weigh at
the end of 8 months?
Answer:
The baby weighed 14.5 pounds at the end of 8 months
Step-by-step explanation:
Proportions
We know a baby weighed 7.25 pounds at birth.
It's given at the end of 8 months, the baby weighed twice its birth weight.
This means the baby weighed 2*7.25 = 14.5 pounds at the end of 8 months.
The baby weighed 14.5 pounds at the end of 8 months
Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape.
Answer:
Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]
Step-by-step explanation:
Total fabric available = 17 yards
fraction used = one-third = 1/3
Let us convert this fraction to actual number
He used one-third of total
= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]
To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:
The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2
[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]
