Answer:
15/3=45/x
We move all terms to the left:
15/3-(45/x)=0
Domain of the equation: x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
-(+45/x)+15/3=0
We add all the numbers together, and all the variables
-(+45/x)+5=0
We get rid of parentheses
-45/x+5=0
We multiply all the terms by the denominator
5*x-45=0
We add all the numbers together, and all the variables
5x-45=0
We move all terms containing x to the left, all other terms to the right
5x=45
x=45/5
x=9

The ratio of fish to turtles in a pond is
20:3. There are 80 fish in the pond.
How many turtles are in the pond?
A 10
14
C 12
D 16
Answer:
C : 12
Step-by-step explanation:
Answer:
12 turtles
Step-by-step explanation:
First, if the ratio of fish to turtles is 20:3 and there are 80 fish, then we know that you have to divide 80 by 4 to get the answer 20. However, to find out how many turtles there are you need to do the opposite and multiply instead of dividing. So you do 3 x 4, which get you your answer.
Hope this helps!

Leon has $50 in a savings account that earns 10% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answer:
$10.50
Step-by-step explanation:
Interest = future value - amount saved
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$50 x (1.1)^2 = $60.50
Interest = $60.50 - $50 = $10.50

Rob is flying a kite with a string that makes a 70-degree angle with the ground. If the kite string is 27 meters long, how high is the kite above the ground?
(Please use the exact ratio to calculate the missing side and round your answer to the nearest hundredth.)
The kite is meters above the ground.
Answer:
25.37
Step-by-step explanation:
Use SOH or Sin∅=[tex]\frac{opposite}{hypotenuse}[/tex]
So Sin(70)= [tex]\frac{x}{27}[/tex]
Multiply both sides of the equation to end up with 27Sin(70)=x
Plug into your calculator in degrees and you get 25.37m

Solve [tex]\sqrt{384}[/tex] without going into decimals.
(Answer is below)
Let's solve this step-by-step.
1. Prime factorization of 384.
[tex]=\sqrt{2^7\times3}[/tex]
2. Apply the exponent rule. (Formula: [tex]a^b^+^c=a^b\times a^c[/tex])
[tex]=\sqrt{2^6\times2\times2\times3}[/tex]
3. Apply the radical rule. (Formula: [tex]\sqrt{ab} =\sqrt{a}\sqrt{b}[/tex] or [tex]a\geq 0,b\geq 0[/tex])
[tex]=\sqrt{2^6} \sqrt{2\times3}[/tex]
3a. Solve 2 to the 6th power.
[tex]\sqrt{2\times2\times2\times2\times2\times2} =8[/tex]
4. Multiply 2 by 3. (Note: Put the 8 in your final answer)
[tex]\sqrt{2\times3} =8\sqrt{6}[/tex]
Your answer is: [tex]8\sqrt{6}[/tex]

What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}
I hope this has helped you and have a wonderful day!

Write an
algebraic expression to represent the area of the shaded region:
2y
4y + 3
Answer:
4y^{2}+3y
Step-by-step explanation:
First you need to distribute the values.
(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials
You Should get
8y^{2}+6y
Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.
8y^{2}+6y/2
Doing this you will get
4y^{2}+3y

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school. If Angela works alone, it will take her five and a half hours. If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
Answer:
3.08 hours
Step-by-step explanation:
Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours.
If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
This is calculated as:
The Number of hours they worked together = T
1/5.5 + 1/7 = 1/T
= 7 + 5.5/(5.5)(7)
= 12.5/38.5
1/T = 12.5/38.5
Cross Multiply
12.5T = 38.5
T = 38.5/12.5
T = 3.08 hours
The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W_1=\dfrac{1}{n}[/tex]
In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,
[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]
If Brandon works alone, it will take him 7 hours. The work done by Brandon in one hour is,
[tex]B=\dfrac{1}{7}[/tex]
The work done in one hour, when the work together,
[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]
Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

Given Point A (3,-4) and Point B (8,6) on directed line segment AB, what is the y-coordinate of Point F
that partitions AB in the ratio of 3:2?
Answer:
(6,2) y-coordinate is 2
Step-by-step explanation:
The coordinates of the point F on directed line segment AB that partitions AB in the ratio 3 :2 are: (6, 2)
What is Coordinate geometry?The formula for finding the coordinates of a point that divides the line in ratio m:n are given by:
We are given that Point A (3,-4) and Point B (8,6) on directed line segment AB.
Here (x1,y1) and (x2,y2) are coordinates of the two points line passed through
(x1,y1) = A(-3,-4)
(x2,y2) = B(8,6)
Ratio: 3 : 2
m = 3
n = 2
Putting the values in the formula
( x, y) = (3 x 8 + 2 x 3 /5 , 3 x 6 + 2 x (-4) /5 )
( x, y) = (24 + 6 / 5 , 18 - 8 /5)
( x, y) = (30/5, 10/5)
( x, y) = (6, 2)
Hence,
The coordinates of the point F are: (6, 2)
