Take 4/8 as an example. Find a number you can divide both numbers with. In this case, it's 4. 4 divided by 4= 1, and 8 divided by 4= 2. So, the simplified version of 4/8 is 1/2. Similarly, with the ration 60:£3, you find the number you can divided both numbers with. In this case, it is 3. 3 divided by 3= 1, and 60 divided by 3= 20.
Final Answer: 20:£1

What is the answer to -2r-4r=0
Answer:
r = 0
Step-by-step explanation:
First, combine like terms:
(-2r - 4r) = 0
(-6r) = 0
Isolate the variable, r. Divide - 6 from both sides:
(-6r)/-6 = (0)/-6
r = 0/-6 = 0
r = 0 is your answer.

Find f(2) for the following functions: f(x) = x - 14
Answer:
f(2) = - 12Step-by-step explanation:
f(x) = x - 14
To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2
We have
f(2) = 2 - 14
We have the final answer as
f(2) = - 12Hope this helps you
Here, we are given with a polynomial f(x)
[tex]f(x) = x - 14[/tex]
And we are asked to find f(2).....?
We can see that, 2 is in place of x. So for finding its value, we need to substitute 2 in place of x.
Substituting 2 in place of x:
[tex]f(x) = x - 14[/tex]
[tex]f(2) = 2 - 14[/tex]
Solving further,
[tex]f(2) = \boxed{- 12}[/tex]
And, we're done with the value of f(2)

Step-by-step explanation:
The diagonal of a cube connects two opposite corners.
You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.
Let the length of the edge be s.
a^2 + b^2 = c^2
[tex] s^2 + 10^2 = (\sqrt{150})^2 [/tex]
[tex] s^2 + 100 = 150 [/tex]

How does the absolute value take away negative signs
Step-by-step explanation:
the absolute value is the numbers UNIT DISTANCE from the origin (0,0). since you can't have negative distance, the result is always positive. Can be solved by counting distance on a graph Not by the actual numbers on the line (-1,-2,-3, etc) but by counting the "boxes" from a point to the origin. hope this makes sense!
Answer:
the absolute value of negative number makes it a positive number

The graph shows the relationship between the total cost and the number of gift cards that Raj bought for raffle prizes. A graph titled Cost of Gift Cards. The x-axis shows the number of gift cards, numbered 1 to 9, and the y-axis shows the total cost in dollars, numbered 10 to 90. Blue diamonds appear at points (1, 20), (2, 40), (3, 60), (4, 80). What would be the cost for 5 of the gift cards? $80 $90 $100 $110
Answer:
the answer is 100$ on endgunuity
Step-by-step explanation:
The cost for 5 of the gift cards is $100. Therefore, option C is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, blue diamonds appear at points (1, 20), (2, 40), (3, 60), (4, 80).
Now, we will find m and c using the points (1,20) and (2,40)
Let x be the number of gifts cards and y is total cost (in $).
The slope, m = (40-20)/(2-1)
m = 20
Equation of straight line is given as,
y = mx + c
Put the value of m,
So, y = 20x + c
Substitute with the point (1,20) in y=20x+c, we get
20 = 20×1 + c
20 = 20 + c
c = 0
The equation of the line, y = 20x
To find the cost for 5 of the gift cards substitute with x = 5
y = 20×5 = 100
So, the cost for 5 of the gift cards = $100
Therefore, option C is the correct answer.

What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Jansen family has 2 1/2 gallons of milk. Each of the 3 family members drinks 1 1/2 cups of milk a day.
1 gallon = 16 cups
2[tex]\frac{1}{2}[/tex] gallons = 2[tex]\frac{1}{2}[/tex] x 16 = 5/2 x 16 = 5 x 8 = 40 cups
Now -
Total milk consumed in 1 day = 3 x 3/2 cups = 9/2 cups = 4.5 cups.
In 8 days, the amount of milk consumed will be = 4.5 x 8 = 36 gallons.
Remaining amount = 40 - 36 = 4 gallons.
Therefore, the amount of milk remaining is equivalent to 4 gallons.

Solve for x and y: 10x=5y+5 y=2x-1
Answer:
So there are infinite solutions along the line y = 2x-1
Step-by-step explanation:
10x=5y+5
y=2x-1
Substitute y into the first equation
10x = 5(2x-1) +5
10x = 10x-5+5
10x = 10x
This is always true
So there are infinite solutions along the line y = 2x-1

Train A and train B stops at Swindon at 10:30 . Train A stops every twelve minutes and train B stops every 14 Mins , when do they both stop at Swindon again ?
Answer: at 11:54
Step-by-step explanation:
Let's define the 10:30 as our t = 0 min.
We know that Train A stops every 12 mins, and Train B stops every 14 mins, they will stop at the same time in the least common multiple of 12 and 14.
To find the least common multiple of two numbers, we must do:
LCM(a,b) = a*b/GCD(a,b)
Where GCD(a, b) is the greatest common divisor of a and b.
In this case the only common divisior of 12 and 14 is 2.
So we have:
LCM(12, 14) = 12*14/2 = 84.
Then the both trains will stop 84 minutes after 10:30
one hour has 60 mins, so we can write 84 minutes as:
1 hour and 24 minutes = 1:24
Then they will stop at the same time at 10:30 + 1:24 = 11:54

John's teacher bought three 64 ounce bottles of soda for a class party. At the end of the party, 1/6 of the soda remained. How many ounces of soda remained?
Answer:
32 ouncesStep-by-step explanation:
If John's teacher bought three 64 ounce bottles of soda for a class party, the total weight of the soda bought will be 3*64 = 192 ounces of soda.
If 1/6 of the soda remained after the party, the amount of ounces that remained is expressed as;
amount of ounces that remained = 1/6 * 192
amount of ounces that remained = 32 ounce
Hence amount of ounces that remained is 32 ounces
