There are 4 blue tiles and 6 red tiles with the letter A written on them in a bag. In the same bag, there are 2 red tiles and 8 blue tiles with the letter B written on them. What is the probability that a randomly selected tile has the letter B or is blue? Give your final answer as the nearest whole percent.
Answers
Answer:
70%
Step-by-step explanation:
4 blue tiles A
6 red tiles A
2 red tiles B
8 blue tiles B
total: 20
total B: 2 + 8 = 10
total blue, not B: 4
p(B or blue) = (10 + 4)/20 = 0.7 = 70%
PLEASE HELP!! SHOW STEPS FOR BRAINLIEST! Pythagorean theorem BASED question:
An artist joined three square regions at their
vertices to create the figure shown in the diagram.
The artist will use small congruent square tiles to
cover each region without any gaps or overlaps.
Based on the information, which statement is true?
A. The number of tiles needed to cover Region X
is the same as the number of tiles needed to
cover both Region Y and Region Z.
B. The number of tiles needed to cover Region Y
is the same as the number of tiles needed to
cover both Region X and Region Z.
C. The number of tiles needed to cover Region Z
is the same as the number of tiles needed to
cover both Region X and Region Y.
D. None of these
Answers
This is a classic proof of the Pythagorean Theorem!
Pythagorean theorem is a^2 + b^2 = c^2. With a square, its area is its side length squared. Therefore, if we think about this as squares, then the sum of the area of square X and square Y will be equal to the sum of square Z.
Looking at your answer choices, the best option is C - The number of tiles needed to cover Region Z is the same number of tiles needed to cover both Region X and Region Y.
Hope this helps!! :)

What is the solution to this equation? log6(x) + log6(3) = log6( x+1)
Answers
Answer:
A
Step-by-step explanation:
got it right
The solution to this equation log₆(x) + log₆(3) = log₆( x+1) is x = 1/2.
What is a logarithm?A logarithm is an exponent or power to which a base must be raised in order to produce a given number. If aˣ = n, then x is the logarithm of n to the base a, which is expressed mathematically as x = logₐn.
How to solve this problem?We know that logₐx + logₐy = logₐ(xy)
Here, log₆(x) + log₆(3) = log₆( x+1)
i.e. log₆(3x) = log₆( x+1)
i.e. 3x = x + 1
i.e. 3x - x = 1
i.e. 2x = 1
i.e. x = 1/2
Therefore, the solution to this equation log₆(x) + log₆(3) = log₆( x+1) is x = 1/2. So, option A is correct.

What is permutation?Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set.
The symbol [tex]P_{r} ^{n}[/tex] = [tex]\frac{n!}{(n-r)!}[/tex]
is used to denote the number of permutations of n distinct objects, taken r at a time.
According to the question
Website requires users to create a password consisting of digits only.
i.e Digits are:
0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 7 , 8 , 9 = total 10 digits
no digit may be repeated and each password must be at least 9 digits.
i.e Digits taken at a time is 9 with no repetitions
Now ,
Applying permutation
[tex]P_{r} ^{n}[/tex] = [tex]\frac{n!}{(n-r)!}[/tex]
substituting the value
n = 10
r = 9
[tex]P_{9} ^{10}[/tex] = [tex]\frac{10!}{(10-9)!}[/tex]
[tex]P_{9} ^{10}[/tex] = 10!
= 3,628,800
Hence, There are 3,628,800 possible ways to create passwords .

solve:
[tex] \sqrt{x} + \sqrt{5 + x} = 15 \div \sqrt{5 + x} [/tex]
Answers
Explanation:
sqrt(x) + sqrt(5 + x) = 15 / sqrt(5 + x)
sqrt(5 + x)[sqrt(x) + sqrt(5 + x)] = 15
sqrt(5x + x^2) + 5 + x = 15
sqrt(5x + x^2) = 10 - x
Take square of both sides
5x + x^2 = (10 - x)^2
5x + x^2 = 100 - 20x + x^2
Cancel x^2
5x = 100 - 20x
25x = 100

find the surface area of a square based pyramid with a side length of 5cm and a slant height of 5cm
Answers
Answer:
Step-by-step explanation:
The surface area of a square pyramid = 1/2 * slant height * base perimeter + area of base
The slant height is 5 cm
The base perimeter is 4 * 5 cm = 20 cm
The area of the base is 5 cm * 5 cm = 25 cm**2
Plugging into the formula the area =
1/2 * 5 cm * 20 cm + 25 cm**2 =
5 cm * 10 cm + 25 cm**2 =
50 cm**2 + 25 cm**2 = 75 cm**2
