Area of a square is side ^2
To find the length of the side using area find the square root of the area.
Side length = sqrt(169)
Side length = 13 feet
Answer:
13 ft
Step-by-step explanation:
The area of a pool is length × width (l × w) , but the length and width are the same so I'll use [tex]b[/tex] representing both length and width:
A = l × w
A = [tex]b^{2}[/tex]
Area of the pool is 169
169 = [tex]b^{2}[/tex]
[tex]b[/tex] = [tex]\sqrt{169}[/tex]
[tex]b[/tex] = 13

if ad and pm are medians of two similar triangles abc and pqr such that ad:pm=4:9, then calculate ar. triangle abc/ar. triangle pqr
Answer:
4/9
Step-by-step explanation:
ad(base)/2 = abc
4x(4y)/2 = 4xy/2 = 2xy
pm(base)/2 = pqr
9x*9y/2 = 9xy/2 = 4.5xy
2xy/4.5 xy = 2/4.5 = 4/9

Perform the indicated operations. Write the answer in standard form, a+bi.
(9 + 2i)(9 - 2i)
Answer:
It can't be expressed in that form
Step-by-step explanation:
From difference of two squares:
[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]
a » 9
b » 2i
[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]
but i² is -1 [ complex numbers ]
[tex] = \{81 - 4( - 1) \} \\ = 81 + 4 \\ = 85[/tex]
Answer:
[tex](9 + 2i)(9 - 2i) \: \\ this \: can \: be \: wrtten \: as \: \\ {9}^{2} - {2i}^{2} = 81 - 4 \times - 1 \\ = 81 + 4 = 85 \\ then \: 85 + 0i \\ thank \: you[/tex]

1 million has 6zeros 320million has 7zerosCanada has a population that is about 1/10 as large as the United States. If Canada's population is about 32 million, about how many people live in the United States? Explain the number of zeros in your the answer.
Solution:-Given,
Population of Canada = 32 million (1/10 of that of the USA)
=> Let the population of the USA be 'x'.
Now,
→ x/10 + 32 (million)
→ x = 32 × 10
→ x = 320 million.
(The number of zeros in 1 million is 6, so the number of zeros in 320 million will be 7)
Answer:-320000000 or 320 million.

solve the following equation(2m)/3 + 1/2 - m/5 = (4m)/5 + 5
Answer:
m = - 13.5
Step-by-step explanation:
Given
[tex]\frac{2m}{3}[/tex] + [tex]\frac{1}{2}[/tex] - [tex]\frac{m}{5}[/tex] = [tex]\frac{4m}{5}[/tex] + 5
Multiply through by 30 ( the LCM of 3, 2, 5 ) to clear the fractions
20m + 15 - 6m = 24m + 150 , that is
14m + 15 = 24m + 150 ( subtract 24m from both sides )
- 10m + 15 = 150 ( subtract 15 from both sides )
- 10m = 135 ( divide both sides by - 10 )
m = - 13.5

A baseball team won 16 games and lost 11. At this rate, how many games will it win in a 162-game schedule?
==========================================================
Explanation:
The team won 16 games and lost 11 so far. At this point in the season, they played 16+11 = 27 games total. Their win rate is 16/27.
Set this equal to x/162 which is the win rate for winning x games out of 162 played over the entire season.
Solve for x.
x/162 = 16/27
27x = 162*16 ... cross multiplication
27x = 2592
x = 2592/27
x = 96
The team would win 96 games if it kept the same winning rate going.
Notice that 16/27 = 0.5926 = 59.26% and how 96/162 = 0.5926 = 59.26% as well (both are approximate). This helps confirm we have the correct answer.
-------------------------
Here's another slightly longer way to solve. If you prefer the first method above, then ignore this section.
w = number of games won over the entire 162 game season
162-w = number of games lost over the entire season
w/(162-w) = win to loss ratio
16/11 = win to loss ratio after winning 16 games and losing 11
Setting those last two expressions equal to each other and solving for w gets us...
w/(162-w) = 16/11
11w = 16(162-w)
11w = 2592-16w
11w+16w = 2592
27w = 2592 ... this hopefully looks a bit familiar from before
w = 2592/27
w = 96 games won

For what values of x is the equation X^2-x=20 true?
Answer: x = 5 or x = -4
Step-by-step explanation:
Given equation
x² - x = 20
Subtract 20 on both sides
x² - x - 20 = 0
Cross factorize the equation
x -5
x 4
Factorize the equation
(x - 5) (x + 4) = 0
[tex]\boxed{x=5}[/tex] or [tex]\boxed{x=-4}[/tex]
