At a concert the ratio of men to women is 5:3
The ratio of women to children is 7:4
Show that more than half of the people at the concert are men.

Answers

Men: 5 : 3 = 20 : 12
Women: 7 : 4 = 21 : 12

So for every 12 children there are 20 men to 21 women.

Neither men nor women compose more than half of the concert population.

Step-by-step explanation:

Answer:

C. 350 pounds

Step-by-step explanation:

Looking at the chart, week 22 would be between the week 20 and week 25 marks. As a result, the weight should be between 275 and 425 pounds. As a result, A is out. Week 22 will be bigger than week 20 (275), so B is also out. Week 22 is in between Week 20 and 25, so it isn't bigger than Week 25's pumpkin; D is out for this reason. That leaves C, 350 pounds, as our answer.

the perimeter of a rectangular court is 224 feet. The length is 4 feet more than the width. Write and solve an equation to find the dimension of the court.​

Answers

Perimeter = 2l + 2w
L=4+x
W= x

224 = 2(4+x) + 2x
224 = 8+2x+2x
216 = 4x
54 = x

Plugging x = 54 into initial dimensions:
L = 54 + 4 = 58
W = 54

Use the points (2, 2485.6) and (6, 1172.5) to write an equation of the line of fit in slope-intercept form. Let x be the years since 2010 and let y be the number of CDs in millions sold.

Answers

Answer:

y = -328.275x + 1829.05

Step-by-step explanation:

In this case, we need to write an equation of this form:

y = ax + b  (1)      a: slope    b: intercept

In order to calculate the slope, we need to use the following expression:

a = y₂ - y₁ / x₂ - x₁     (2)

So, we have two points here, so, from these points we can identify each of the elements so we can determine the slope.

Point 1: (2, 2485.6)

Point 2: (6, 1172.5)

The slope of this equation will be:

a = 1172.5 - 2485.6 / 6 - 2

a = -328.275

Now that we have the slope, to get the intercept "b", we just use any of the given points, and replace in the general equation (1) to solve for b:

2485.6 = -328.275(2) + b

b = 2485.6 - 656.55

b = 1829.05

With the value of a and b, we can write the general equation of the line for this:

y = -328.275x + 1829.05

In your own words, what is a radical expression?

Answers

Answer:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.

The term underneath the radical symbol is called the radicand.

1. Maggie keeps track of daily bird sightings. The table below shows the number and type of swans that were seen in one day. What percent of the swans were mute swans? Round your answer to the nearest tenth of a percent.

Answers

Answer:

hello! i just did this problem and the answer is 12.2%

Step-by-step explanation:

first we need to add all of the swans together, then from there you take the amount of mute swans and divide it by the sum of all the swans! finally, multiply by 100 to convert into a percent and round it to 12.2%

hope this helped plz give me brainliest! <3

The solution is 12.2 %

The percentage of mute swans is given by the equation A = 12.2 %

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage of mute swans be represented as A

Now , the equation will be

Let the total number of swans be S

The number of mute swans = 5  swans

The number of Trumpeter swans = 34 swans

The number of Tundra swans = 2 swans

So , the total number of swans S = 5 + 34 + 2 = 41 swans

And , the percentage of mute swans A = ( number of mute swans / total number of swans S ) x 100

Substituting the values in the equation , we get

The percentage of mute swans A = ( 5/41 ) x 100

On simplifying the equation , we get

The percentage of mute swans A = 0.1219 x 100

The percentage of mute swans A = 12.19

The percentage of mute swans A = 12.2 %

Therefore , the value of A is 12.2 %

Hence , the percentage is 12.2 %
