Divide 1 hour in the ratio 1:5
Answer: ratio of 1: 10mins
ratio of 5: 50mins
Step-by-step explanation:
The ratio of 1:
[tex]\frac{1}{6}[/tex] x 60 (hours should be converted to minutes therefore it is 60 mins and
the denominator seen here is taken by adding the two values in the
given ratio and since we're still finding 1 you should divide 1 by the
added denominator and the same applies when finding the ratio 5)
Answer= 10mins
The ratio of 5:
[tex]\frac{5}{6}[/tex] x 60 (refer to the underlined explanation above)
answer= 50mins
so if you want to verify you add the two values you got to see if you got 60 as 60mins in hours was divided in ratio so when you add it will be 60 which means your answer is correct!
Answer: 12:60
Step-by-step explanation: To find the ratio, we must take 1 h and turn it into minutes. So as we know, it's 60 minutes. So next, we shall change the ratio into fraction form (don't worry it's the same basic format)
[tex]\frac{1}{5} = \frac{?}{60}[/tex]
So with that given information, we know that 60 would be our denominator. So, we need to divide both denominators, and then whatever we get from that, multiply that by the given numerator. So, we would do:

12 * 1
= 12
Therefore we now know that 1/5 = 12/60 as a ratio. I hope this helped :)

Is linear equations in two variables easy class 10?.
Linear equations in two variables can be relatively easy to understand and work with, as they represent straight lines in the xy-plane. The slope-intercept form of a linear equation, y = mx + b, is a simple way to represent a line with a specific slope and y-intercept.
Graphing linear equations is also straightforward, as you can find the x-intercept and y-intercept and plot the line using these points.
However, solving linear equations in two variables can become more challenging when the equations involve multiple terms or are presented in a different form. Also, understanding the concept of slope, y-intercept, and how to graph the line can be challenging for some students.
Overall, linear equations in two variables can be considered as a fundamental concept in algebra and mathematics and it requires practice to gain mastery over it.

For each rhombus, find each angle measure or segment length.
Answer:34xt25
Step-by-step explanation:
Can a linear system only have 2 solutions?.
Most linear systems will have exactly one solution. Nevertheless, it is possible that there are no solutions or infinitely many. (but It is not possible that there are exactly two solutions of a linear system.)
Let's assume a system of two linear equations, then, there are three possibilities of solutions.
The possibilities are:
Two parallel lines
e.g. y = 3x + 1
y = 3x − 2 (with the same slope, different intercepts)
Two (distinct) intersecting lines
As we know two straight lines cannot meet at two points. Two points determine only one line (not two lines).
e.g. y = 3x + 1
y = 5x − 2 (different slopes)
These equations have the same line as their graphs
If two lines do have two points in common, then "the lines coincide" (which really means "there is only one line".) In this case, we say, "the two lines are the same".

Dylan is hosting a party she buys pumpkins 20 dollars each and balloons 2 dollars each she has a budget of 250 if x represents pumpkins and y represents balloons write an inequality that represents all possible ways she could buy a pumpkin and balloons what is the max number of ballons she could buy
Answer:
Dylan's budget is $250, and she is buying pumpkins for $20 each and balloons for $2 each. We can represent the total cost of the pumpkins as 20x and the total cost of the balloons as 2y. The inequality that represents all possible ways she could buy pumpkins and balloons within her budget is:
20x + 2y <= 250
To find the maximum number of balloons she could buy, we can use the equation above and set x = 0, and then solve for y.
20(0) + 2y <= 250
2y <= 250
y <= 125
The maximum number of balloons she could buy is 125.

[Real world example] A sewage treatment centre fills a cylindrical silo with waste. The diameter is 20m and the height 5m. It is full to the top with 1300kg of waste. Find the density of the waste.
Step-by-step explanation:
density is mass/volume.
usually it is expressed as grams/cm³.
the question does not give us the information about the dimensions for density. so, I am going with my assumption.
the volume of a cylinder is
ground area × height
the ground area is a circle, so this is
pi×r²×height
r is the radius and therefore half of the diameter.
so, we have in our case as volume :
pi×(20/2)²×5 = pi×100×5 = 500pi = 1,570.796326... m³
1 m = 100 cm
1 m³ = 100×100×100 = 1,000,000 cm³
so, the volume of our cylinder is then also
1,570,796,326.7948966192... cm³
1 kg = 1000 g ("kilo" means 1000)
1300 kg = 1,300,000 g
so the standard density is
1,300,000/1,570,796,326.7948966192... g/cm³ =
= 0.000827606... g/cm3
The density of the waste is approximately 0.827 kg/m³.
What is density?A physical property is known as density gauges a substance's mass per unit volume. It is referred to as the mass-to-volume ratio.
The volume of a cylinder is given by the formula V = πr²h, where r is the radius of the base of the cylinder and h is the height.
Since the diameter of the silo is 20m, the radius is 10m. Therefore, the volume of the silo is:
V = π(10m)²(5m) = 500π m³
Since the silo is full to the top with 1300kg of waste, the density of the waste is:
density = mass/volume
density = 1300kg/(500π m³)
density ≈ 0.827 kg/m³
Therefore, the density of the waste is approximately 0.827 kg/m³.

Alyson deposits $500 in the bank for 12 years. The bank offers her a 4% interest rate compounded monthly. How much money will be in her account at the end
of the 12 years? (Remember to round your answer to the nearest cent.)
A-$ type your answer.....
Answer:$917.58.
Step-by-step explanation:
The formula for compound interest is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, the initial deposit is $500, the annual interest rate is 4%, the number of times compounded per year is 12 (monthly), and the number of years is 12.
So, we can plug in the values into the formula:
A = $500(1 + 0.04/12)^(12*12) = $500(1.003333333)^(144) = $500(1.835170816) = $917.585
The final amount in her account after 12 years is $917.58
To round to the nearest cent, we can use the following method:
If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.
If the digit in the thousandths place is greater than 5, we round up the hundredths digit.
In this case the digit in the thousandths is 5 so, we have to round up the hundredths digit of $917.58.
So, the final amount in her account after 12 years is $917.59.
Answer: $800.516
Step-by-step explanation:
We use the equation
A = P(1 + )^nt
P = principal
r = rate of interest
t = times
Now let's solve
P = $500
r = 4% = 0.04
t = 12 years
A = $500(1 +[tex]\frac{0.04}{12}[/tex] ) ^12 = $800.516
