4/5=?/15 (urgent) <3
Answer:
12
Step-by-step explanation:
Let the missing number be " x ".
4 / 5 = x / 15
4 * 15 = 5 * x
x = ( 4 * 15 ) / 5
= 4 * 3
x = 12
Answer:
12
Step-by-step explanation:
[tex]\frac{4}{5} = \frac{?}{15} \\\\Cross-multiply\\\\4 * 15 = 60\\60 / 5 = 12[/tex]

Answer:
m∠ABD = 24°, m∠CBD = 24°, m∠ABC = 48°
Step-by-step explanation:
3x+6=7x-18
3x-7x=-18-6
-4x=-24
x=24÷4
=6
Hence, ∠ABD = (3x+6)°
= [3(6)+6]°
= (18+6)°
= 24°
Hence, ∠CBD = 24°
Hence, ∠ABC = 24°×2
= 48°
Suppose one card is drawn at random from a standard deck.
Answer each part. Write your answers as fractions.
(a) What is the probability that the card drawn is a seven?
(6) What is the probability that the card drawn is a diamond?
(c) What is the probability that the card drawn is a seven or a diamond?
Answer:
a) 4 cards out of 52 will be seven, therefore 4/52 = 1/13
b) 13 cards out of 52 will be diamonds, therefore 13/52 = 1/4
c) 13 diamonds, and 3 seven (1 seven already diamond), therefore 16/52 = 4/13

Determine whether the inverse of F(x) is a function.
Answer:
f⁻¹(x) is not a function
Step-by-step explanation:
A function can only have one output value per input value. Multiple input values can have the same output value (horizontally), but multiple output values cannot have the same input value (vertically).
For example:
[tex]f(x)=x^2\\f(-2)=-2^2=4\\f(2)=2^2=4[/tex]
This function has 2 inputs with the same output. That is valid.
However, if you take the inverse of that function:
[tex]f^{-1}(x)=\sqrt{x}\\f^{-1}(2)=\sqrt{2}=1.414\\f^{-1}(-2)=\sqrt{-2}=\sqrt{2}i[/tex]
f⁻¹(-2) is an imaginary number. It doesn't exist, and so the inverse of f(x) is still a function because there is no vertical overlap. This is shown more clearly in the attached image.
The graph of the inverse of a function is just mirrored over y = x. This is also shown in the attached image. Any horizontal overlap the function may have becomes vertical overlap, and if those values still exist, the function cannot be a function.
In the function in your question, f(x) has some horizontal overlap around x = 0 and x = 8. If this was mirrored over y = x, the function at x = 8 would have 2 outputs, y = 0 and y = 8. As a result, it cannot be a function.
Let me know if I need to explain any part of that more clearly.

Answer:
yes5 × (6 - 3) = (5 × 6) - (5 × 3)Step-by-step explanation:
The distributive property tells you the factor outside parentheses multiplies each of the terms inside parentheses.
The difference 6 -3 inside parentheses has two terms, and there is a factor of 5 outside those parentheses. The setup for the distributive property is there, so the distributive property can be used.
__
The outside factor multiplies each inside term. The sign can be left with the inside term, or can be placed between the products.
5 × (6 - 3) = (5×6) - (5×3)
__
or
5 × (6 - 3) = (5×6) +(5×(-3))
Pls help with this question in geometry and pls show steps thank you
Answer:
9 cm
Step-by-step explanation:
In a 30°-60°-90° triangle, the ratio of the shortest to the longest sides is 1 : 2.
That means DB = 1/2BC = 3 cm. It also means AB = 2BC = 12 cm.
Then the length of AD is ...
AD +DB = AB
AD = AB -DB = 12 cm -3 cm
AD = 9 cm

9514 1404 393
Answer:
B. 3/5
Step-by-step explanation:
The distance from the origin to the point is given by the distance formula:
d = √((x -0)² +(y -0)²) = √(3² +(-4)²) = √25 = 5
The cosine of the angle is the ratio of x-coordinate to that distance:
cos(θ) = 3/5

Answer:
4
Step-by-step explanation:
irst note that 6/8=6/8=9/12, which shows that these are similar triangles. Any of these fractions is the ratio of corresponding sides. Reduce it and find the denominator
Two triangles are known to be similar if the ratio of the similar sides and angles are equal. The value of n, if the two triangles are similar is 3.75
What are similar triangles?Two triangles are known to be similar if the ratio of the similar sides and angles are equal.
From the given triangles, we have the following
Scale factor = 3/n
Determine the ratio of the sides
Ratio = 12/15 = 3/n
Cross multiply
12n = 15 * 3
12n = 45
n = 3.75
Hence the value of n, if the two triangles are similar is 3.75

How are the graphs of the reciprocal functions related to their corresponding original functions? What happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? Describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions.
Answer:
Graphs of reciprocal functions reflect against their original functions. For example, y=arcsinx reflects against y=sinx. To graph trigonomoetric functions, simply use a graphing calculator, like Desmos. It's easy. go to Desmos and type y=sinx. It will make a graph for you. Then on a line below the function, type y=arcsinx. You will notice how the inverse of sine reflects against sine. I would teach a visual person by not saying as much and just writing out the equations and using Desmos. To an auditory person, I'd explain as I do the math. I don't know what some of these words mean, but if someone wants a physical example, I'd give them a realistic world problem. I'd ask them to stand up and imagine they are this many feet away from an object that is this many feet tall. We will set up a realistic equation together.
