Answer:
Janie is wrong, as Alex made the better three-row record. This is because if you work out the percentage of three-rows of both Elizabeth and Alex, the percentage of Elizabeth would be 36% and Alex's 40%. Therefore, it can be concluded that Alex made the better three-row.
Step-by-step explanation:
- Elizabeth = 9/25 X 100 = 36%
- Alex = 8/20 X 100 = 40%
Janie is wrong, as Alex made the better three-row record.
What is Percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
It is given that in a basketball contest,
9 out of 25 free throw attempts are done by Elizabeth.
8 out of 20 free throw attempts are done by Alex .
According to the given data , Elizabeth had a better free-throw record was said by Janie because Elizabeth made more free throws than Alex. So We are required to check who had made the free throw record.
So let us calculate the three row records of both Elizabeth and Alex.
- Elizabeth = 9/25 X 100 = 36%
- Alex = 8/20 X 100 = 40%
So Janie is wrong, as Alex made the better three-row record.
Once we find the percentage of three-rows of both Elizabeth and Alex, the percentage of Elizabeth we get 36% and Alex's 40%.
Therefore, it can be concluded that Alex made the better three-row.
Hence Janie is wrong, as Alex made the better three-row record.

Anna has a total of 36 goldfish in her aquarium, some are orange and some are black. The number of orange goldfish is 7 more than twice the number of black goldfish. Which system of equations below can be used to describe the number of black and orange goldfish in Anna's aquarium?
Answer:
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
Step-by-step explanation:
Let the number of:
Orange goldfish = x
Black gold fish = y
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black.
x + y = 36.....Equation 1
The number of orange goldfish is 7 more than twice the number of black goldfish.
x = 7 + 2y...... Equation 2
We can rewrite this as:
x - 2y = 7..... Equation 2
The system of equations below that can be used to describe the number of black and orange goldfish in Anna's aquarium is :
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
I think it’s
X + y= 36
X - 2y= 7

Answers:
a = 8r = -15%y = 4.9 approximatelyNote: your teacher may want you to type in a positive value for r
=========================================================
Explanation:
The given equation y = 8(1-0.15)^t is in the form y = a(1+r)^t
We have a = 8 as the initial value, or what we start with.
r = -0.15 converts to -15%, so we have a decay of 15%
Plug in t = 3 to find the corresponding value of y
y = 8(1-0.15)^t
y = 8(1-0.15)^3
y = 8(0.85)^3
y = 8(0.614125)
y = 4.913
y = 4.9
Answer:
a = 8
r = 85%
y = 4.913
Step-by-step explanation:
For a, the exponential decay function is y=a*r^t. In order to find the initial amount, you are solving for when t = 0 or, y(0). Thus, t, or time, is 0. Solve the equation with time of 0.
y = 8(1-0.15)^0 = 8*1 (anything to the 0 power equals 1)
a = 8 is the initial amount
In order to solve for r, you need to solve (1 - 0.15) = 0.85. Now, multiply by 100 to get the percent 100 * 0.85 = 85%
Lastly, when t = 3 solve the equation filling in the exponent, t with 3 like below:
y = 8(1-0.15)^3 (PEMDAS; parenthesis and exponents first)
y = 8(0.85)^3 = 8*(0.614125)
y = 4.913

How do I do this problem (similar right triangles) please explain how you did it!!
ASAP!!!
Answer:
by phythagoras theorem
(c+b)^2=(8)^2+(6)^2
(b+c)^2=64+36
(b+c)^2=100
b+c=√100
b+c=10.
by phythagoras theorem
(8)^2=(a)^2+(b)^2
64-b^2=a^2. {1}
by phythagoras theorem
(6)^2=(a)^2+(c)^2
36-c^2=a^2. {2}
In equation 1 and 2,
64-b^2=36-c^2
64-36= -c^2+b^2
28= b^2-c^2
28=(b+c)(b-c)
28=10(b-c)
b-c=28/10
b-c=2.8.
b+c=10
b-c=2.8
subtract both equations
c=3.6
option A is correct.

Answer:
x = 2 and y = 5
Step-by-step explanation:
Given
x = y - 3.....i)
2x + 3y = 19.........ii)
Putting x = y - 3 in equation II)
2( y - 3 ) + 3y = 19
2y - 6 + 3y = 19
5y = 19 + 6
5y = 25
y = 25 / 5
y = 5
Now putting y = 5 in equation i)
x = 5 - 3
x = 2
