Answer:
4 : 18 and 6 : 27
Step-by-step explanation:
To obtain equivalent ratios, multiply or divide both parts of the ratio by the same quantity.
Multiplying by 2
2 : 9 = 2(2) : 9(2) = 4 : 18
Multiplying by 3
2 : 9 = 2(3) : 9(3) = 6 : 27 , etc
What is the solution of 2d=a-b/b-c when you solve for a
Answer:
2d(b-c)+b=a
Step-by-step explanation:
First you start off with the equation given
2d=(a-b)/(b-c)
Second, you want to start getting A by its self so that means you have to multiply both sides by (b-c) to get (a-b) by its self. (underlined portion cancles out)
2d(b-c)=((a-b)/(b-c)) (b-c) ----> 2d(b-c)=a-b
Finally, you want to add b to both sides to get a completely by it's self. (underlined portion cancles out)
2d(b-c)+b=a-b+b -----> 2d(b-c)+b=a

The lines CA and AB will sum up to CB.
What are collinear points?Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry.
Given here: CA and AB along the same line CB also A,B,C are collinear also ∠DAB+∠CAD=180 as they are adjacent angles and thus are supplementary. Therefore CA+AB=CB

A totem pole that is 90 feet tall casts a shadow that is 45 feet long. At the same time, a 6 – foot tall man casts a shadow that is x feet long. Find the length of the shadow.
Answer:
x=90+45/6
x=135/6
x=22.5
The length of the shadow of the 6-foot tall man is 3 feets
Actual Length :
Length of pole = 90 feets Length of man = 6 feetsLength of shadow :
Pole shadow = 45 feets Shadow of man = xUsing the relation :
(Pole length/shadow) = (man's height / shadow) (90 / 45) = (6 / x) Cross multiply :90x = 270x = 270 / 90 x = 3Therefore, the shadow of the man is 3 feets long.

Plsssss help me I’m finna die
Answer:
She is 90 feet above ground before she begins to descend.
She descends by a rate of 5 feet per second.
Step-by-step explanation:
She is 90 feet above ground before she begins to descend. You can see that by looking at the y value of the highest point of the line, which is just between 80 and 100, which is 90.
We can find the rate of her descending by finding the slope. Remember that the slope formula is (y1-y2)/(x1-x2)
We can find two points on the line and plug the x and y values in. Let's use the points (0, 90) and (16, 10).
We plug the values in:
(90-10)/(0-16)
(80)/-16
-5
The slope is negative, which makes sense, because Aretha is descending and not ascending.
So, she is descending by a rate of 5 feet per second.

Let me know if this helps :)
Answer: 14
Step-by-step explanation: It’s a good idea to get into the habit of
using parentheses when substituting numbers in for variables.
Since a = 9 and b = 4, 2a - b is 2(9) - (4).
Now think about your order of operations.
Multiplication comes before subtraction so first multiply 2(9) to get 18.
So we have (18) - (4) which is 14.

What is Logical operator?A logical operation is a particular symbol or term that joins two or more informational expressions. It is most commonly used to determine if a connection between two sentences is true or untrue.
Given that p ↔ q represents the statement "He is wearing a coat if and only if the temperature is below 30°F.” Therefore, event p is He is wearing a coat, while event q represents the temperature below 30°F.
Now, In p^q, '^' represents the 'and' operator. Therefore, p^q represents He is wearing a coat and the temperature is below 30°F.
Hence, the correct option is B.

Consider the function f(x) = x^2 – 331. Chivonne claims a domain restriction x ≥ 0 produces the inverse function f–1(x) = √ x - 331 .
Which statement describes whether Chivonne is correct?
A) The expression for f–1(x) is correct, but the domain restriction is not.
B) The domain restriction is correct, but the expression for f–1(x) is not.
C) Both the expression for f–1(x) and the domain restriction are correct.
D) Neither the domain restriction nor the expression for f–1(x) is correct.
Answer:
The correct option is;
D) Neither the domain restriction nor the expression for f⁻¹(x) is correct
Step-by-step explanation:
The given function can be written as follows;
f(x) = x² - 331
The inverse of the function f(x), which is f⁻¹(x), can be found as follows;
Let f(x) = x² - 331 = y, we have;
f(x) + 331 = x²
x = √(f(x) + 331)
We replace x with f⁻¹(x) and f(x) with x, to get;
f⁻¹(x) = √(x + 331)
We note that the domain of the inverse function will include values from x ≥ -331, and the correct inverse function √(x + 331) ≠ √x - 331
Therefore, we have that neither the domain restriction nor the expression for f⁻¹(x) is correct.
Answer:
B) The domain restriction is correct, but the expression for f–1(x) is not.

The answer is
[tex]\sqrt{2} \: \: or \: \: 1.414[/tex]Step-by-step explanation:
[tex]h(x) = {2}^{x} [/tex]To solve the equation we must first find h-¹(x)
To find h-¹(x) equate h(x) to y
That's
[tex]y = {2}^{x} [/tex]Next interchange the terms
x becomes y and y becomes x
That's
[tex] {2}^{y} = x[/tex]Make y the subject
Take logarithm to base 2 to both sides
That's
[tex] log_{2}( {2} )^{y} = log_{2}x \\ y log_{2}2 = log_{2}(x) [/tex]But
[tex] log_{2}(2) = 1[/tex][tex]y = log_{2}(x) [/tex]So we have
[tex] {h}^{ - 1} (x) = log_{2}(x) [/tex]Now we can solve the equation
We have
[tex] log_{2}(x) = 0.5[/tex]Convert the logarithm into exponential form using the fact that
[tex] log_{a}(x) = b \: \: \cong \: \: x = {a}^{b} [/tex]So we have

is the following a true statement? 4/8 < 5/16
Answer:
No, because 4/8*2= 8/16
And 8/16 is greater than 5/16
Answer:
The statement is false.
Step-by-step explanation:
The easiest way to answer this question is to make both fractions have the same common denominator. In this case, we should alter the first fraction to have a denominator of 16 so that it matches the second fraction. To do this, we should multiply both the numerator and the denominator of the fraction by 2 (this is the same as multiplying by 1, which does not change the value of the fraction). This is modeled below:
4/8 * 2/2 = 8/16
Now, we can plug this value back into our original statement.
8/16 < 5/16
From comparing the numerators, we know that 5 is NOT greater than 8, so the statement is false.
Hope this helps!

Jojo's arcade grand opening first 3 games free 75 cents after three games if carlose saved up 9.00 dollars from his allowance how much games could he play
Answer:
Carlos could play a total of 15 games
Step-by-step explanation:
In the grand opening of JoJo's arcade:
First 3 games are free
75 cents after the first 3 free games
Carlos has $9 saved from his allowance
75 cents = $0.75
Number of games Carlos could play = Total saved allowance / cost per game after 3 free games
= $9 / $0.75
= 12 games
Total number of games Carlos could play = free games + games from his allowance
= 3 + 12
= 15 games
Carlos could play a total of 15 games
Inverse Function -5 + 5/2x
Answer:
y = (2/5)x + 2
Step-by-step explanation:
To find the inverse of a function, we simply exchange the variables x and y and solve for y.
For this function we will write it as such:
y = -5 + (5/2)x
So to find the inverse, we will swap the x and y and solve.
y = -5 + (5/2)x
x = -5 + (5/2)y
x + 5 = (5/2)y
(2/5) * (x + 5) = y
(2/5)x + (2/5)5 = y
(2/5)x + 2 = y
Thus the inverse of the function is:
y = (2/5)x + 2
Cheers.
