Answer: 1/4

Add: 3/4 + 1/6 = 3 · 3 / 4 · 3 + 1 · 2 / 6 · 2 = 9/12 + 2/12 = 9 + 2/12 = 11/12

Subtract:  1 - 2/3 = 11/12 - 2/3 = 11/12 - 2 · 4 / 3 · 4 = 11/12 - 8/12 = 11 - 8/12 = 3/12 = 3 · 1 / 3 · 4 = 1/4

The designs that meet the condition have leg lengths that are in the ratio of 1: 12.

Two ramps that meet the Americans Disabilities Act are;

The needed measure of the angle of a ramp according to the Americans with Disability Act is θ ≤ 4.8°.

Given, the ratio of the leg lengths is 1: 12, we have;

Expressed as a fraction, we have;

The required ratio of leg lengths = [tex]\frac{1}{12}[/tex]

Probable leg lengths are seen by multiplying the numerator and denominator of the above fraction by a constant as follows;

Possible leg length for the ramp = [tex]\frac{1 * 3}{12 * 3} = \frac{3}{36}[/tex]

The range in statistics for a given data set is the difference between the highest and lowest values.

As a result, the range can also be defined as the difference between the highest and lowest observations. The range of observation is the name given to the outcome. In statistics, the range indicates the dispersion of observations.

To find the range in statistics, we need to arrange the given values or set of data or set of observations in ascending order.

For example, if the given data set is {2,5,8,10,3}, then the range will be 10 – 2 = 8.

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.

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:

60 / 5

= 12

12 * 1

= 12

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

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.

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.

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".

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.

Equivalent 7/8 is equals to 56/64 in fractions.

In mathematics, equivalent fractions are those with the same denominator but different numerators. For instance, since they both equal 1, 2/4 and 3/6 are comparable fractions. An element of the whole is a fraction. To represent identical components of the total, equivalent fractions are utilized.

The numerator and denominator of each fraction can be multiplied by the same integer to determine the equivalent fraction. Equivalent fractions are those that, despite visible differences, signify the same value. For instance, if you take a piece of cake, divide it into two equal pieces, and then eat one of them, you will have consumed half of the cake.

Answer:34xt25

Step-by-step explanation:

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

A right triangle is a particular kind of triangle that only has one right (90°) angle.A mathematical formula for determining the length of the third side of a right triangle given the lengths of the other two sides was developed by the Greek mathematician Pythagoras.

The sides of variables a and b make up the right angle of the triangle. Any side may make use of any variable. The variable c stands for the left side, or the side that leans away from the right angle. The longest side, or side c, is always present and is known as the hypotenuse.
