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

In the right ABC above, the length of the side BC is 4.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

Given;

Side BA= [tex]\sqrt{11}[/tex]

Side AC= [tex]\sqrt{5}[/tex]

BC^2=BA^2+AC^2

BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2

BC^2= 11+5

BC^2= 16

BC= 4

Therefore, the Pythagoras theorem gives answer 4

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

[-4±√4² - 4(-1)(-12)] / 2(-1)

= [-4 ± √16-48] / -2

Answer:

the ladder will be unstable because it is 18.33ft from the bottom of the building

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.

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.

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

Angle GHM and Angle LKJ

Step-by-step explanation:

They are both marked the same with one line.

The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3

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

28.8%​ is the probability that a data value is between 48 and 52.

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%.
