Each side of a square x units long is decreased by 9 units. Which expression represents the area of the new square in square units? *
Given:
Side of a square = x units
The side of square is decreased by 9 units.
To find:
The expression that represents the area of the new square in square units.
Solution:
It is given that, the side of a square is x units and it is decreased by 9 units. So, the side of new square is:
[tex]\text{New side length}=x-9[/tex]
The area of a square is:
[tex]Area=(side)^2[/tex]
So, the area of the new square is:
[tex]Area=(x-9)^2[/tex]
[tex]Area=(x)^2-2(x)(9)+(9)^2[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]Area=x^2-18x+81[/tex]
Therefore, the expression for the area of the new square is either [tex](x-9)^2[/tex] or [tex]x^2-18x+81[/tex], both are equivalent.

x = ___ cm
Answer:
x = 7
Step-by-step explanation:
5/(40+5) = 3/(2x+10+3)
1/9 = 3/(2x+13)
2x+13 = 3×9
2x = 27 - 13
x = 14/2
x = 7
Answer:
Step-by-step explanation:
Since they are directly proportional:
5cm -> 3cm
40cm -> y
y = 120/5
= 24cm
2x+10 = 24
2x = 14
x = 7cm

A. 5/12
B. 12/5
C. 13/12
D. 5/13
From the question given above, the following data were obtained:
Cos θ = 12/13
Sine θ =?
Next, we shall determine the opposite. This can be obtained as follow:
[tex]Cos \theta = \frac{Adjacent}{Hypothenus}\\\\Cos \theta = \frac{12}{13}[/tex]
Adjacent = 12
Hypothenus = 13
Opposite =?Hypothenus² = Opposite² + Adjacent²
13² = Opposite² + 12²
169 = Opposite² + 144
Collect like terms
169 – 144 = Opposite²
25 = Opposite²
Take the square root of both side
Opposite = √25
Opposite = 5Finally, we shall determine the Sine θ. This can be obtained as follow:
Opposite = 5
Hypothenus = 13
Sine θ =.?[tex]Sine\theta = \frac{Opposite}{Hypothenus}\\\\Sine\theta = \frac{5}{13}[/tex]
Therefore, the value of Sine θ is 5/13

A square pyramid with a height of 7 inches has a volume of 47.25 cubic inches. Find the side length of the square base.
The side length is inches.
Answer:
4.5 inches
Step-by-step explanation:
volume= 1/3 (base area) × height
47.25= 1/3 ( base area) × 7
20.25 = base area
now since the base is a square we can evaluate base area = length²
20.25= length²
length = 4.5 inches

Nine times a number, subtracted from the square of the number, is 36. Find the two numbers.
Answer:
- 3 and 12
Step-by-step explanation:
let n be the number , then
n² - 9n = 36 ( subtract 36 from both sides )
n² - 9n - 36 = 0
Consider the factors of the constant term (- 36) which sum to give the coefficient of the n- term (- 9)
The factors are - 12 and + 3 , since
- 12 × 3 = - 36 and - 12 + 3 = - 9 , then
(n - 12)(n + 3) = 0
Equate each factor to zero and solve for n
n - 12 = 0 ⇒ n = 12
n + 3 = 0 ⇒ n = - 3
The 2 numbers are - 3 and 12

The function y=15,000(1.10)xmodels the cost of annual tuition at a local college, x years after 2000. How much will tuition be in 2025?
Answer: [tex]162,520.588[/tex]
Step-by-step explanation:
Given
The function [tex]y=15,000(1.1)^x[/tex] models the cost of tuition fees after year 2000
In year 2025 that is 25 years after 2000, fees can be given as
[tex]\Rightarrow y=15,000(1.1)^{25}\\\Rightarrow y=15,000\times 10.834\\\Rightarrow y=162,520.588[/tex]
Thus, the fees in year 2025 is [tex]162,520.588[/tex].
Randy has 36 tiles.
How should he arrange them so that he has the smallest perimeter?
A.
4 by 9 rectangle
B.
3 by 12 rectangle
C.
1 by 36 rectangle
D.
6 by 6 rectangle
Answer:
Smallest perimeter setup is (6 by 6 rectangle)
Step-by-step explanation:
Given:
Total number of tile = 36
Find:
Smallest perimeter setup
Computation:
Perimeter = 2(a + b)
So,
Perimeter if (4 by 9 rectangle )
Perimeter if (4 by 9 rectangle ) = 2[4+9]
Perimeter if (4 by 9 rectangle ) = 2[13]
Perimeter if (4 by 9 rectangle ) = 26
Perimeter if (3 by 12 rectangle )
Perimeter if (3 by 12 rectangle ) = 2[3+12]
Perimeter if (3 by 12 rectangle ) = 2[15]
Perimeter if (3 by 12 rectangle ) = 30
Perimeter if (1 by 36 rectangle )
Perimeter if (1 by 36 rectangle ) = 2[1+36]
Perimeter if (1 by 36 rectangle ) = 2[37]
Perimeter if (1 by 36 rectangle ) = 74
Perimeter if (6 by 6 rectangle )
Perimeter if (6 by 6 rectangle ) = 2[6+6]
Perimeter if (6 by 6 rectangle ) = 2[12]
Perimeter if (6 by 6 rectangle ) = 24
So,
Smallest perimeter setup is (6 by 6 rectangle)

Answer:
Value of An if n is 17 = -834
Step-by-step explanation:
Given:
A100 = 245
d = 13
n = 17
Find:
Value of An if n = 17
Computation:
An = a + (n-1)d
A100 = a + (100-1)13
245 = a + (99)17
245 = a + 1,287
a = 245 - 1,287
a = -1,042
So,
Value of An if n = 17
An = a + (n-1)d
A17 = -1,042 + (17-1)(13)
A17 = -1,042 + (16)(13)
A17 = -1,042 + 208
A17 = -834
Value of An if n is 17 = -834

A spinner has 8 equal-sized sections. Six of the sections are green. What is the probability that the spinner will land on green?
_________ out of 8 or ________%
Answer:
6/8
Step-by-step explanation:
or to simplify it, it would be 3/4
The probability that the spinner will land on green is 6 out of 8 or 75%.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Number of equal sections on the spinner = 8
Number of sections which are green = 6
Probability can be calculated as the ratio of number of desired outcomes to the total number of outcomes.
Here,
Desired outcome is the spinner landing on green.
Probability = 6/8 = 0.75 = 75%
Hence the probability is 6 out of 8 or 75%.
