20 is 80 percent of what number?
Answers
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.

C 7ft, 24 ft, 25 Ft
D 5ft. 7 ft, 12 ft
Answers
Step by step explanation
16 ft,30 ft 34ft
The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.
What is a right triangle?The right is a triangle with has one angle 90° and square of hypotenuse is equal to the sum of square of other two legs.
Given that, the set of measurements representing the side lengths of a right triangle,
We will check the measurements by seeing if they are following the Pythagoras theorem or not,
Option A)
16 ft, 30 ft, 34
16²+30² = 1156 = 34²
∴ 16²+30² = 34²
Option B)
9²+12² = 225 = 15²
9²+12² = 15²
Option C)
7²+24² = 625 = 25²
7²+24² = 25²
Option D)
5²+7² = 74 ≠ 12²
Since, 5ft. 7 ft, 12 ft set of measurements are not following the Pythagoras theorem.
Therefore, it's not a right triangle.
Hence, The set of measurements could not represent the side lengths of a right triangle is 5ft. 7 ft, 12 ft.

Consider the following pattern:

1.1.1 Find an expression for the nth term of the
sequence
(3)
Answers
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
[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.

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 :]
Answers
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

Answer:
The value of x is 19.
Step-by-step explanation:
The steps are :
3(x- 9) = 30
3(x - 9) ÷ 3 = 30 ÷ 3 [eliminate 3 on left side]
x - 9 = 10
x - 9 + 9 = 10 + 9 [eliminate -9 on left side]
x = 19

Answers
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:
[tex]t= \frac{324.04}{32}[/tex]
[tex]t= 10.13s[/tex]

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
Answers
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
