Hello!
Answer:
First, write 0.63 as 0.63/1
Then, multiply both numerator and denominator by 10 for every number after the decimal point.
0.63x100/1x100=63/100
so your answer is 63/100 :)

what numbers have a sum of 20 and the difference is 4
Answer:
16 and 2
Step-by-step explanation:
I'm not sure honestly if this is correct, but I hope this helps.
Answer:
The numbers are 12 and 8
Step-by-step explanation:
let the numbers be x and y :
[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]
add (a) and (b):
[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]
find y:
[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

(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]

if f(x)=3-2x and g(x)= 1-x+5, what is the value of (f/g) (8)?
Answer: -169
Step-by-step explanation:
There are two ways to answer this question, and one is a lot easier than the other. The first is to divide f(x) by g(x) and then substitute 8 for x, which could take a very long time and would be a huge pain.
On the other hand, you can substitute 8 into the equation f(x), and get
f(8) = 3- 2(8) = 3-16 = -13
Then substitute 8 into g(x) and get
g(8) = 1 /(8 +5) = 1/(13)
Then you simply divide the two to get -13/(1/13). Here, you can multiply the numerator and the denominator of the larger fraction by 13, so you would end up with -169/1, or, the answer to your problem: -169.

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.

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

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

Answer:
(3x+4)(x-5)
Step-by-step explanation:
Consider the given line segment. If AC is 39cm long, answer the following questions:
A
B
9x+7
-3x+20
AB -
BC =
Is point B the midpoint? (yes or no)
The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint
AB + BC = AC
9x + 7 + (-3x + 20) = 39
9x + 7 - 3x + 20 = 39
6x + 27 = 39
6x = 39 - 27
6x = 12
x = 12 / 6
x = 2
9x + 7 = - 3x + 20
9(2) + 7 = - 3(2) + 20
25 = 15
Hence,
Since, AB ≠ BC, then B is not the midpoint

Answer:
The GCF is going to be 9
Step-by-step explanation:
When finding the GCF, you want to do prime factorization of each number.
18's prime factorization is, 2 × 3 × 3, which equals 18
36's prime factorization is 2 × 2 × 3 × 3, which equals 36
45's prime factorization is 5 × 3 × 3, which equals 45
Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer
