A 12-foot by 15-foot patio is increased by placing a stone border around the patio. The width of the border is the same all around the patio.The perimeter of the patio after it is expanded is 74 feet.
Complete question :
A 12-foot by 15-foot patio is increased by placing a stone border around the patio. The width of the border is the same all around the patio.The perimeter of the patio after it is expanded is 74 feet. The equation which represents x, the width of the border is 2[(12+2x)+15+2x)]=74. What is the width of the border?
1) 2 1/2 feet
2) 3 feet
4) 5 feet
5) 8 1/2 feet
Answer:
2.5
Step-by-step explanation:
Solving for X in the perimeter equation :
2[(12+2x)+15+2x)]=74
Open the bracket
2[(12 + 2x + 15 + 2x)] = 74
2(27 + 4x) = 74
54 + 8x = 74
8x = 74 - 54
8x = 20
x = 20/8
x = 2.5
Hence, width fo border = 2.5

Which mapping diagram represents a function ? Would it be D?
Answer:
D
Step-by-step explanation:
Mathematically , for us to have a function, no 2 y values must have a single x value
Although, 2 x-values can have a single y value
The y values called the output values are listed on the right
The x values called the input values are listed on the left
So out of the options, with the given definition above, the one that represents a function is the option D

Find the length of each arc. Use the exact answer
Answer:
D) 16π/3 ft
Step-by-step explanation:
The Question is calculated using Arc length formula
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
Hence, the arc length = Option D = 16π/3 ft

Jayden took a number n and increased it by 25%. Then, he doubled the resulting product.
Which of the following is equivalent to these two steps and would result in the same final number? Show your work.
doubling the number and then decreasing the result by 25%
increasing the number by 50%
multiplying the number by 1.25
multiplying the number by 2.5
Answer:
Step-by-step explanation:
increasing he number by 50%
look 25 x 2 = 50 woah duable means add th number again boom 50%
Answer:
third option (mult by 1.25)
Step-by-step explanation:
let's say the number is 10
now double it to get 20
now increase it be 25% which is the same as multiplying by 125% or 1.25; you will get 25

Answer:
The volume at the highest point is 64 times greater
Step-by-step explanation:
Mathematically, the volume of a sphere is simply the same formula irrespective of the size
Now, we have the formula as;
V = 4/3 * pi * r^3
While the 4/3 pi is a constant term, the value of r changes
initially we have the value of r as d = 2
where r is the radius and d is the diameter
we have this as;
8/2 = 4 ft
r^3 of this is 4^3 = 64
For the second part, we have
r as 32/2 = 16 ft
now, the r^3 part here is 16^3 = 4096
So now, we have to divide the final by the initial
we have this as 4096/64 = 64
So the volume at the highest point is 64 times greater

The age of Sita is five years more than Gautam's age. 5 years ago, the ratio of their ages was 3:2. Find their present ages.
The age of Sita is five years more than Gautam's age. 5 years ago, the ratio of their ages was 3:2. Find their present ages.
Solution:-The age of Sita = (x + 5) years.
And, the age of Gautam = x years.
Now,
5 years ago, the ratio of their ages was 3 : 2
[tex] \therefore [/tex] [tex] \bf \frac{3}{2} \: = \frac{x \: + \: 5}{x} [/tex]
Now by cross multiplying, we get,
3x = 2(x + 5)
3x = 2x + 10
3x - 2x = 10
x = 10Hence, the age of Sita = (x + 5) = (10 + 5) = 15 years.
And, the age of Gautam = x = 10 years.
Now,
The present age of Sita = 15 + 5 = 20 years. (Answer)
And, the present age of Gautam = 10 + 5 = 15 years. (Answer)

Let’s say you want to play a new card game called Pokee. Every player isdealt 4 cards and everyone compares what hands they have to see who wins. Our job isto figure out what the hierarchy of the hands should be. Below is a list of several scoringhands that we wish to compare. For each hand, count how many hands of that type thereare (include the expression you used to get that value) along with a simple explanation ofhow you got that expression. Assume a standard 52 card deck with 4 suits.
a) Presidential Flush (J, Q, K, Ace, all the same suit)
b) Straightish (4 consecutive cards)
c)Flushed (4 cards of the same suit)
d) House (Two pairs of different cards)
Answer:
a)
Step-by-step explanation:
base on the hierarchy of the hands should be
Straight flush - Poker hand in with 4 consecutive cards of the same suit
Flush - Poker hand with any 4 cards of the same suit
Full house - Poker hand that contains three of the same cards and one pair
Since: Poker hand refers to the 4 cards that are held in the game. Every game features the same hierarchy of poker hands. Based on this hierarchy, there can be different types of poker hands:

A man invests $16800 in a savings plan that pays simple interest at a rate of 5% per annum. Find the time taken for his investment to grow to $19800.
Answer: 3.57 years
Step-by-step explanation:
Based on the question given, the interest is the difference between the amount and the principal which will be:
= $19800 - $16800
= $3000
The formula for Simple interest is given as:
Interest = Principal × Rate × Time
3000 = 16800 × 5% × Time
3000 = 16800 × 0.05 × Time
3000 = 840 × Time
Time = 3000 / 840
Time = 3.57
The time taken to grow the investment is 3.57 years

Factor n2 + 8n + 12 completely.
Answer:
(n+2)(n+6)Step-by-step explanation:
[tex]n^2+8n+12\\\\[/tex]
Break the expressions into groups
[tex]=\left(n^2+2n\right)+\left(6n+12\right)\\\\[/tex]
Factor out n from n^2+2n
Factor out 6 from 6n+12
[tex]=n\left(n+2\right)+6\left(n+2\right)[/tex]
Factor out common term : n+2
[tex]=\left(n+2\right)\left(n+6\right)[/tex]
The factors of the quadratic equation by applying the factorization method are (n + 2) and (n + 6).
Given that,
The quadratic equation is,
n² + 8n + 12
Used the factorization method to factor the quadratic equation.
Now, factor the equation,
n² + 8n + 12
n² + (6 + 2)n + 12
n² + 6n + 2n + 12
n (n + 6) + 2(n + 6)
(n + 2) (n + 6)
Therefore, the factors of the equation are (n + 2) and (n + 6).

The front view of the top of a house is in the shape of a triangle whose

used to find the value of b?
Answer:
uiptyftyfkghfcytfghvchjcghcfgcjvbcfg
Step-by-step explanation:
Answer:
2nd option
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 75, b = b , h = b - 10, then
[tex]\frac{1}{2}[/tex] b(b - 10) = 75 ( multiply both sides by 2 to clear the fraction )
b(b - h) = 150 ← option 2
