Answer:
10³⁰
Step-by-step explanation:
firstly working out without the power of 3
[tex]( \frac{10 {}^{15} }{10 {}^{5} } )[/tex]
this is the same as 10¹⁵ ÷ 10⁵
here the bases are the same and it's division so we subtract the powers
15 - 5 = 10
10¹⁵ ÷ 10⁵ = 10¹⁰
we are left with (10¹⁰)³, multiply the powers
10 × 3 = 30
final answer = 10³⁰
Hey there!
(10^15/10^5)^3
10^15
= 1,000,000,000,000,000
10^5
= 10 * 10 * 10 * 10 * 10
= 100 * 100 * 10
= 10,000 * 10
= 100,000
(1,000,000,000,000,000/100,000)^3
= (10,000,000,000)^3
= 10,000,000,000 * 10,000,000 * 10,000,000
= 100,000,000,000,000,000 * 10,000,000
= 10^30
Therefore, your answer is: 10^30

Step-by-step explanation:
A swimming pool is to be constructed in a 1,408-ft2 backyard. There is to be a fence that will surround a 12-by-24-foot pool. The pool builder wants to build a concrete paver deck of a uniform width, x, surrounding the pool and filling the entire area of the backyard. What is the width of the pool deck?
9 ft
10 ft
11 ft
12 ft
Answer:
B. 10 ftStep-by-step explanation:
Let the width of the pool deck be x.
Dimensions of the pool are 12 + 2x and 24 + 2x.Total area is 1408 ft².We have equation:
(12 + 2x)(24 + 2x) = 140812*24 + 12*2x + 24*2x + (2x)² = 1408288 + 72x + 4x² = 14084x² + 72x + 288 - 1408 = 04x² + 72x - 1120 = 0x² + 18x - 280 = 0x² - 10x + 28x - 280 = 0x(x - 10) + 28(x - 10) = 0(x - 10)(x + 28) = 01)
x - 10 = 0x = 102)
x + 28 = 0x = - 28 (discarded as negative)Correct choice is B
The width of the pool deck is 10 feet (x = 10).
So, the answer is option B: 10 ft.
Here, we have to find the width of the pool deck, we need to calculate the total area occupied by the pool and the deck and then find the value of x that makes the total area equal to 1,408 square feet.
First, let's calculate the area of the pool.
The pool is 12 feet by 24 feet:
Area of the pool = Length × Width
Area of the pool = 12 ft × 24 ft
Area of the pool = 288 ft²
Now, we want to add the deck around the pool.
The length and width of the entire area (pool + deck) will be (12 + 2x) feet and (24 + 2x) feet, respectively, because we add x feet to both sides of the pool.
Area of the entire area (pool + deck) = (12 + 2x) ft × (24 + 2x) ft
We want this area to equal 1,408 square feet:
(12 + 2x) ft × (24 + 2x) ft = 1,408 ft²
Now, we can solve for x:
(12 + 2x) × (24 + 2x) = 1,408
Expand the equation:
288 + 48x + 24x + 4x² = 1,408
Combine like terms:
4x² + 72x - 1,120 = 0
Now, let's solve this quadratic equation for x.
We can either factor it or use the quadratic formula:
Using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a
where a = 4, b = 72, and c = -1,120.
x = (-(72) ± √(72² - 4 * 4 * -1,120)) / 2 * 4
x = (-72 ± √(5,184 + 17,920)) / 8
x = (-72 ± √23,104) / 8
x = (-72 ± 152) / 8
Now, we have two possible solutions:
x = (-72 + 152) / 8
x = 80 / 8
x = 10
x = (-72 - 152) / 8
x = -224 / 8
x = -28
Since we are interested in a positive width for the deck, the width of the pool deck is 10 feet (x = 10).
So, the answer is option B: 10 ft.

We have given a right angled triangle whose values are m, n and 2[tex]\bold{\underline{ To \: Find :- }}[/tex]
We have to find the value of m and n[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]
In the given right angled triangle, we have
Perpendicular height = n units Base = 2 unitsHypotenuse = m unitsNow, By using trigonometric ratios

[tex]\bold{\red{ Cos Φ = }}{\bold{\red{\frac{Base}{Hypotenuse }}}}[/tex]

[tex]\bold{ 1/√2= }{\bold{\frac{2}{m}}}[/tex]
[tex]\bold{\red{ m = 2√2 \: units }}[/tex]
We know that , Sum of Angles of triangle is 180° .Therefore,
Let the unknown angle be x
[tex]\sf{ 45° + x + 90° = 180° }[/tex]
[tex]\sf{ x = 180° - 135 ° }[/tex]
[tex]\sf{ x = 45° }[/tex]
Now,
[tex]\bold{ Cos \: x° = }{\bold{\frac{n}{2√2}}}[/tex]
[tex]\bold{ Cos \: 45° = }{\bold{\frac{n}{2√2}}}[/tex]

Solve the following recurrence relation:
[tex]A_{n}=a_{n-1}+n; a_{1} = 0[/tex]
By iteratively substituting, we have
[tex]a_n = a_{n-1} + n[/tex]
[tex]a_{n-1} = a_{n-2} + (n - 1) \implies a_n = a_{n-2} + n + (n - 1)[/tex]
[tex]a_{n-2} = a_{n-3} + (n - 2) \implies a_n = a_{n-3} + n + (n - 1) + (n - 2)[/tex]
and the pattern continues down to the first term [tex]a_1=0[/tex],
[tex]a_n = a_{n - (n - 1)} + n + (n - 1) + (n - 2) + \cdots + (n - (n - 2))[/tex]
[tex]\implies a_n = a_1 + \displaystyle \sum_{k=0}^{n-2} (n - k)[/tex]
[tex]\implies a_n = \displaystyle n \sum_{k=0}^{n-2} 1 - \sum_{k=0}^{n-2} k[/tex]
Recall the formulas
[tex]\displaystyle \sum_{n=1}^N 1 = N[/tex]
[tex]\displaystyle \sum_{n=1}^N n = \frac{N(N+1)}2[/tex]
It follows that
[tex]a_n = n (n - 2) - \dfrac{(n-2)(n-1)}2[/tex]
[tex]\implies a_n = \dfrac12 n^2 + \dfrac12 n - 1[/tex]
[tex]\implies \boxed{a_n = \dfrac{(n+2)(n-1)}2}[/tex]

Answer:
594 in²
Step-by-step explanation:
There are several ways to do this.
divide the shaded region into rectangles, and add their areasdivide the shaded region into trapezoids and add their areassubtract the white space from a bounding rectangle.Given the way the figure is dimensioned, the last strategy is the easiest.
A rectangle that surrounds the entire figure will be 36 inches wide and 22 inches high. The white space rectangle in the lower right corner is shown to be 18 inches wide and 11 inches high.
The area of a rectangle is the product of its length and width:
A = LW
So the difference in area between the "bounding" rectangle and the whitespace rectangle is ...
shaded area = (36 in)(22 in) -(18 in)(11 in) = 792 in² -198 in²
shaded area = 594 in²
_____
Additional comment
You can also recognize that the dimensions of the cut out corner are each half the overall dimensions. That means the shaded area is 3/4 of the overall "bounding" rectangle. There are several ways you can make use of that fact.
What is the value of x ? (Make sure you give the value of x !!!!)
A 20 degrees
B 50 degrees
C 30 degrees
D. 40 degrees
Answer:
The value of x is 20 degrees.
Step-by-step explanation:
The three angles of a triangle must equal 180 degrees.
100 + 40 + 2x = 140 + 2x
180 - 140 = 40 (goal)
2(x) = 40
2(20) = 40
