Use this calculator for problems like this
https://www.calculator.net/triangle-calculator.html
The length of the base is 18.33 feet greater than 15 feet then the ladder will be unstable.
What is a Pythagorean theorem?Pythagorean theorem states that in the right-angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.
Given that a 20-foot ladder is placed against a building and must just reach a window that is 8 feet of the level ground the latter will be unstable if the base is more than 15 feet from the bottom of the building.
Calculate the base of the triangle by using the Pythagorean theorem:-
H² = P² + B²
B² = H² - P²
B² = 20² - 8²
B = √( 400 - 64 )
B = √336 = 18.33 feet
Therefore, the length of the base is 18.33 feet greater than 15 feet then the ladder will be unstable.

A pile of cards contains red and blue
cards. The ratio of blue cards to red
cards is 5:7, and there are 15 blue
cards in the pile. What is the total
number of cards in the pile?
Answer:
There are 36 cards
Step-by-step explanation:
let blue be B and red be R
B:R =5:7
B/R = 5/7
there are 15 blue cards...
15/R = 5/7
make R subject of the formula...
R = (15×7)/5
R = 21
there are 21 red cards and 15 blue cards
Total number of cards = red cards + blue cards
= 21 + 15
= 36 cards

6^10/6^4
Answer:
6^6
Step-by-step explanation:
Divide the terms with the same base by subtracting their exponents.
6^10 - 4 = 6^6
Answer:
6^6, which equals 46656
Step-by-step explanation:
So when dividing things with exponents in them, you subtract the exponents. With this, you would do:
6^10/6^4 = 6^10 - 6^4 ---> 6^6
The answer would be 6^6, which equals 46656
Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

Suppose a normal distribution has a mean of 48 and a standard deviation of 5. What is the probability that a data value is between 48 and 52? Round your answer to the nearest tenth of a percent. O A. 26.2% . B. 30.5% O c. 31.1% O D. 28.8%
Answer:
31.1 best answer
sorry if it's wrong
28.8% is the probability that a data value is between 48 and 52.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
First, we need to standardize the values and use a standard normal distribution table or calculator.
The standardized value of 48 is:
z = (48 - 48) / 5 = 0
The standardized value of 52 is:
z = (52 - 48) / 5 = 0.8
Now we need to find the probability that a data value is between z = 0 and z = 0.8 in a standard normal distribution. We can use a standard normal distribution table or calculator to find this probability.
Using the table or calculator, we can find that the probability of a data value being between z = 0 and z = 0.8 in a standard normal distribution is approximately 0.2881.
Rounding this answer to the nearest tenth of a percent, we get:
P(48 < x < 52) ≈ 28.8%
Therefore, the answer is D, 28.8%.

Answer:
negative square root will result in zero x-intercepts
Step-by-step explanation:
there are no x-intercepts because if you use the quadratic formula on the equation you get a negative square root which results in zero x-intercepts
in this case, a=-1, b=4, c=-12
