Answer:
20
Step-by-step explanation:
Step 1: 4 = 20% × Y
Step 2: 4 = 20/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
Step 3: Y = 4 × 100/20
Step 4:Y = 4 × 100 ÷ 20
Step 5: Y = 20
The number of Aussies in the group is 20
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of Aussies in the group be = A
The number of Aussies in the group who has blue eyes = 4
The percentage of Aussies that have blue eyes = 20
So , the percentage equation is
20 percentage of total number of Aussies have blue eyes = 4
And ,
( 20 / 100 ) x A = 4
Multiply by 100 on both sides , we get
20A = 400
Divide by 20 on both sides , we get
A = 20
Therefore , the value of A is 20
Hence , the total number of Aussies in the group is 20

Answer:
Angle ABF is 120°.
Step-by-step explanation:
Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.

what is the multiplicative rat of change of the function?
2/3
3/4
4/3
3/2
Answer:
3/4
Step-by-step explanation:
The "multiplicative rate of change" refers to the rate at which the function increases. The rate of exchange below is [tex]\frac{3}{4}[/tex] because if you multiply this to every value of y, the product is the next value of y.
[tex]\frac{3}{2}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{9}{8}[/tex] [tex]\frac{9}{8}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{27}{32}[/tex][tex]\frac{27}{32}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{81}{128}[/tex]If the function continues, the next value would be: [tex]\frac{243}{512}[/tex]
Such constant rate causes an "exponential growth."

The function f(x) = x2 has been translated 9 units up and 4 units to the right to form the function g(x). Which represents
g(x)?
O g(x) = (x + 9)2 + 4
O g(x) = (x + 9)2 - 4
O g(x) = (x - 4)2 + 9
O g(x) = (x + 4)2 + 9
Answer:
g(x)=(x-4)^2+9
Step-by-step explanation:
The function representing the g(x) is g(x) = (x - 4)² + 9.
What is Translation of Functions?Translation of functions is defined as the when each point in the original graph is moved by a fixed units in the same direction.
There are horizontal translation and vertical translation of functions.
Given is a function f(x).
f(x) = x²
A horizontal translation makes the function f(x) to f(x ± k), where k is the unit of translation.
And the vertical translation results in f(x) = f(x) ± k.
Here function f(x) = x² has been translated 9 units up.
f(x) → f(x) + 9 = x² + 9
Then it is translated 4 units to the right,
g(x) = (x - 4)² + 9, since the translation is towards right.
Hence the correct answer is g(x) = (x - 4)² + 9.

A linear inequality is an inequality that involves a linear function.
Examples of linear inequality are: 2x + y < 5, x + y > 2, y - x
A linear equation is represented as:
[tex]\mathbf{y = mx + b}[/tex]
A linear inequality can be gotten from a linear equation by changing the equality sign to any of the following inequality sign: >, < !=, >= and <=
So, examples of linear inequality are:
2x + y < 5, x + y > 2, y - x >= 2, 12x + 4y <= 20 and 6y - 7x > 1

Chris had 30 minutes to do a three-problem quiz. He spent 11 3/4 minutes on question A and 4 1/2 minutes on question B. How much time did he have left for question C?
Answer:Chris spent 13 3/4 minutes on question C
Step-by-step explanation:
First let's write an equation:
We know 30 is the total and we are trying to find a part, and 11 3/4 is a part and 4 and 1/2 is a part
So:
30=11 3/4 + 4 1/2 + x
30=16 1/4 + x
- 16 on both sides(to find what x equals to)
13 2/4=x
X=13 3/4

Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)
radius=6
In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°. Find the length of r, to the nearest inch.
the value of r will be 970 inches Approx.
What are the properties of Triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
Given, In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°.
From the general formula of side of triangle:
c² = a² +b² - 2ab * cos ∠C
In Our case,
a = p = 220
b = q = 890.
c = r
∠C = ∠R = 121 degrees
Thus,
r² = 220² + 890² - 2*220*890 * cos 121°
r² = 941344.455067
r = 970.229073501
r = 970 inches Approx.
Therefore, the value of r will be 970 inches Approx.

Margaret deposits $1,000 in a savings account that pays 1.4% interest compounded
semiannually. What is her balance after 1 year?
Answer:
The balance after 1 year is;
$1,014.05
Step-by-step explanation:
To do this, we use the compound interest formula
That will be ;
A =P (1 + r/n)^nt
A is the amount generated which we want to calculate
r is the rate = 1.4% = 0.014
P is the amount deposited = $1,000
n is the number of times it is compounded annually which is 2 (semi-annually means 2 times in a year)
this the number of years which is 1
we have this as:
A = 1,000( 1 + 0.014/2)^(2*1)
A = 1,000(1 + 0.007)^2
A = 1,000(1.007)^2
A = $1,014.05
