You need to fence in a rectangular piece of land for your dog to run and play. The length is 3 times the width. If the perimeter is 120 ft, what are the dimensions of your very own dog park?
Answer:
Width = 15 feet
Length = 45 feet
Step-by-step explanation:
You need to fence in a rectangular piece of land for your dog to run and play. The length is 3 times the width. If the perimeter is 120 ft, what are the dimensions of your very own dog park?
Perimeter of a rectangle = 2L + 2W
The length is 3 times the width.
L = Length = 3W
W = Width
P = 120 ft
Hence:
120 = 2L + 2W
120 = 2(3W) + 2W
120 = 6W + 2W
120 = 8W
W = 120/8
W = 15 feet
Solving for Length
L = 3W
L = 3 × 15 feet
L = 45 feet
Therefore, the dimensions of your very own dog park is
Width = 15 feet
Length = 45 feet

A standard bathtub holds 70 gallons of water. On average, it takes 7 and 1/2 minutes to drain a bathtub. How many gallons of water go down the drain each minute?
Answer:
9[tex]\frac{1}{3}[/tex] gallons of water
Step-by-step explanation:
To find how many gallons of water go down each minute, divide the total number of gallons of water by the number of minutes it takes to drain:
70/7.5
= 9[tex]\frac{1}{3}[/tex]
So, 9[tex]\frac{1}{3}[/tex] gallons of water go down the drain each minute

Consider the following pattern:
87; 84; 81 ...
1.1.1 Find an expression for the nth term of the
sequence
(3)
Answer:
The nth term of the arithmetic sequence is;
90 - 3n
Step-by-step explanation:
Here, we want to find an expression for the nth term of the sequence
Mathematically, let us determine the type of sequence
As we can see;
84 - 87 = 81-84 = -3
The difference between the terms is a constant; this means that the sequence is arithmetic
The nth term of an arithmetic sequence can be represented by;
Tn = a + (n-1)d
in this case, a is the first term of the sequence = 87
d is the common difference of the sequence = -3
The nth term is thus;
Tn = 87 + (n-1)-3
Tn = 87 - 3n + 3
Tn = 87 + 3 - 3n
Tn = 90 - 3n

If EFGH is an isosceles trapezoid , EH = 4x-27, FG = x + 9 , EG = 3y + 19 and FH=11y-21, solve for x and y.
Answer: X = 12, Y = 5
Step-by-step explanation:
4x-27 = x+9
+27 +27
4x = x + 36
-x -x
3x = 36
3x/3 = 36/3
X = 12
3y + 19 = 11y - 21
+21 +21
3y + 40 = 11y
-3y -3y
40 = 8y
40/8 = 8y/8
Y = 5
The values of x and y are 12 and 5, respectively
The given parameters are:
EH = 4x-27FG = x + 9EG = 3y + 19FH= 11y - 21The slant sides of an isosceles trapezoid are equal.
So, we have:
[tex]EH =FG[/tex]
This gives
[tex]4x - 27 = x + 9[/tex]
Collect like terms
[tex]4x - x = 27 + 9[/tex]
[tex]3x = 36[/tex]
Divide through by 3
[tex]x = 12[/tex]
Also, the diagonals of an isosceles trapezoid are equal.
So, we have:
[tex]EG = FH[/tex]
This gives
[tex]3y + 19 = 11y - 21[/tex]
Collect like terms
[tex]11y - 3y =19 + 21[/tex]
[tex]8y = 40[/tex]
Divide through by 8
[tex]y = 5[/tex]
Hence, the values of x and y are 12 and 5, respectively

20 is 80 percent of what number?
Answer:
20 is 80 of 25
Explanation:
20x10/8=25
A percentage is a way to describe a part of a whole. 20 is 80% of 25.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the number be x. Therefore, we can write,
80% of x = 20
0.80 × x = 20
x = 20/0.8
x = 25
Hence, 20 is 80% of 25.

[Will Give Brainliest, please help! ♥] The South Memorial School is designing a new playground. There will be a walkway that diagonally crosses the square playground. The walkway is 55 meters long.
I | Include a sketch of the playground and find the length of one side. Round your answer to the nearest 10th. (I've already completed the sketch, as you can see!)
II | Use your answer from Part I to find the perimeter of the playground. Round your answer to the nearest 10th. Show your work.
Helping me understand or giving me the answer would help me out a lot! THank you :]
Answer:
Perimeter = 155.6 m
Step-by-step explanation:
Notice from the diagram, that the 55 meters long diagonal is the hypotenuse of a right triangle who has equal legs. Then we can use Pythagoras to find the length of the equal legs of the square:
[tex]hyp^2 = leg_1^2 + leg_2^2\\55^2 = 2\,*\,leg^2\\3025=2*leg^2\\leg=\sqrt{\frac{3025}{2} } \\leg\approx 38.89 \,\,meters[/tex]
Therefore, the perimeter of the square playground is 4 times this value:
Perimeter = 38.89 m *4 = 155.56 m
Since they want the answer rounded to the nearest 10th, we write:
Perimeter = 155.6 m
Answer: I. 38.9 II. 155.6
Step-by-step explanation:
So we are working on 2 isosceles right triangles formed by the diagonal and two sides as it has two sides of the same length and two 45 degree angles. The two equal sides of an isosceles triangle are known as 'legs' whereas the third or unequal side is known as the 'hypotenuse'
The sides of isosceles right triangles have a peculiar relationship, 1:1:√2, and one way to find the sides is to use the "pattern formula," which only applies to these triangles:
Hypotenuse= Leg*√2
We don't know the answer to the legs yet, so we have to divide both sides by √2.
L= H/√t2= 1/2H*√2. Since our hypotenuse is 55:
L= 1/2*55*√2= (55*1)/2*√2= 27.5*√2
The square root of 2 is 1.414, so multiply:
27.5*1.414= 38.9 (the length of each side.)
If you want to simplify the equation a little more, here is another way of writing it;
sides length²*2=diagonal length².
Since we know each side length, all we have to do to find the perimeter of the square is to:
Perimeter = 4*side
155.6 = 4*38.9

A soil supplement that weighs 16 lb contains iron, potassium, and mulch. The supplement contains thirteen times as much mulch as iron and twice as much potassium as iron. Find the amount of mulch in the soil supplement. lb
Answer:
The answer is below
Step-by-step explanation:
Let x represent the amount of iron, y represent the amount of potassium and z represent the amount of mulch.
Since the supplement weighs 16 lb, hence:
x + y + z = 16 (1)
Also supplement contains thirteen times as much mulch as iron. Therefore:
x = 13z
x - 13z = 0 (2)
The supplement also has twice as much potassium as iron, hence:
x = 2y
x - 2y = 0 (3)
solving equations 1, 2 and 3 simultaneously gives:
x = 10.1 lb, y = 5.1 lb, z = 0.8 lb
This means that the soil supplement contains 0.8 lb of mulch

Which statement is true about the data sets of two sets of quiz scores?
Sample A: 5, 5, 5, 5, 5 Sample B: 2, 2, 2, 2, 17
Select one:
Samples A and B have the same mean, but Sample A has a smaller median than Sample B.
Samples A and B have the same median, but Sample A has a larger mean than Sample B.
Samples A and B have the same median, but Sample A has a smaller mean than Sample B.
Samples A and B have the same mean, but Sample A has a larger median than Sample B.
Answer: Samples A and B have the same mean, but Sample A has a larger median then Sample B.
Step-by-step explanation:
The median is the middle number in the sequence.
To find the median, place the numbers in order. Then take away, or cross out, one number from each side. Keep going until you are down to one or two numbers. If there is only one number left, that’s your median. If two, add the numbers together and divide by 2.
The mean is the average. To get the mean you add up all the values and subtract that sum by how many numbers there are in the sequence.
Option D is correct for the given conditions, Samples A and B have the same mean, but Sample A has a larger median than Sample B.
What are measures of central tendency?The descriptive summary of a data set is known as the central tendency in statistics. It reflects the center of the data distribution through the use of a single number from the dataset. Additionally, it only provides a summary of the dataset rather than information on specific data within the dataset. In general, several statistical metrics can be used to determine a dataset's central tendency.
Given the data sets of two sets of quiz scores,
Sample A = 5, 5, 5, 5, 5
sample B = 2, 2, 2, 2, 17
mean is the average of total samples,
mean of sample A = (5 + 5+ 5 + 5 + 5 )/5
mean of sample A = 5
Mean of sample B = (2 + 2 + 2+ 2 + 17)/5
mean of sample B = 5
since the mean of both sample are same,
median is the central digit of sets
median of A is 5 and the median of B is 2,
so the median of sample A is larger than sample B.
Hence option D is correct.

H=-16t^2+122t+5 where h is height in feet and t is time in seconds. How long will it take the baseball to hit the ground? h=-16t^2+162t+0.2 where h is height in feet and t is time in seconds. How long will it take the golf ball to hit the ground?
Answer:
[tex]t= 7.67[/tex]
[tex]t= 10.13s[/tex]
Step-by-step explanation:
Solving (a):
[tex]H=-16t^2+122t+5[/tex]
Required: Time to hit the ground
This means that H = 0
So, we have:
[tex]0=-16t^2+122t+5[/tex]
Rewrite as:
[tex]16t^2-122t-5=0[/tex]
Solve for t using:
[tex]t= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]t= \frac{122 \± \sqrt{(-122)^2 - 4*16*-5}}{2*16}[/tex]
[tex]t= \frac{122 \± \sqrt{15204}}{2*16}[/tex]
[tex]t= \frac{122 \± 123.3}{32}[/tex]
Split:
[tex]t= \frac{122 + 123.3}{32}[/tex] or [tex]t= \frac{122 - 123.3}{32}[/tex]
[tex]t= \frac{245.3}{32}[/tex] or [tex]t= \frac{-1.3}{32}[/tex]
[tex]t= 7.67[/tex] or [tex]t= -0.0406[/tex]
Time can not be negative. so: [tex]t= 7.67[/tex]
Solving (b):
[tex]h=-16t^2+162t+0.2[/tex]
Required: Time to hit the ground
This means that h = 0
[tex]0=-16t^2+162t+0.2[/tex]
Rewrite as:
[tex]16t^2-162t-0.2= 0[/tex]
Solve for t using:
[tex]t= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]t= \frac{162 \± \sqrt{(-162)^2 - 4*16*-0.2}}{2*16}[/tex]
[tex]t= \frac{162 \± \sqrt{26256.8}}{32}[/tex]
[tex]t= \frac{162 \± 162.04}{32}[/tex]
[tex]t= \frac{162 + 162.04}{32}[/tex] or [tex]t= \frac{162 - 162.04}{32}[/tex]
[tex]t= \frac{324.04}{32}[/tex] or [tex]t= \frac{-0.04}{32}[/tex]
Time can not be negative. So:
