The list below shows the number of medals that one nation's team won at the Olympics. What is the ratio of gold medals to the total number of medals that the team won? Gold 34 Silver 30 Bronze 39

Answers

Answer:

34:103

Step-by-step explanation:

Add up all the numbers and then put gold then : then the numbers added up

A proportion exists an equation that sets two ratios at the same value.

34 : 103 exists the ratio of gold medals to the total number of medals that the team won 103.

What is the difference between ratio and proportions?

When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage. A ratio is a comparison between two values. A ratio is created when two ratios are equal.

If a ratio depicts the same relationship, it is proportionate. Two ratios can be written as fractions and then reduced to determine if they are proportionate to one another. You have proportionate ratios if the reduced fractions are equal.

Use ratios to compare two things.

The formula for the ratio of any two quantities is expressed as

a : b ⇒ a/b.

On the other hand, the proportional formula is

a : b :: c : d ⟶ ab = cd

a : b :: c : d ⟶ ab = cd

Types of proportion

Direct proportionReverse proportioncompound proportionContinued proportion

34 : 103 exists the ratio of gold medals to the total number of medals that the team won 34 + 30 + 39 = 103

A new television set was recently purchased for a common room in a residence hall for $408.00 including tax. If the tax rate is 2%, find the price of the television set before taxes

Answers

Answer:

$400

Step-by-step explanation:

To solve this, we need to understand how one reaches the final price. The general formula for final price (with tax) is:

t(c) = p x (1+t)

t(c) is total cost

p is price

t is tax rate as a decimal

To find p, we need to create a new formula. Since we have the total cost ($408) and the tax rate (2% or .02), we can divide the total cost by 1 + the tax rate to solve for the price:

t(c) / (1+t) = p

408 / (1+.02) = $400

Answers

Hey there! I'm happy to help!

Since this mural is a square, all the sides are the same. This means that you square on of the sides to get the area (multiply it by itself). If we have the area and want to find a side, we just go backwards and use something called the square root!

If we plug this into our calculators...

√138≈11.74734

We see that is closest to B. 12 ft.

Find f(-5) and f(12) for each piecewise function f(x){-4x+3 if x<3
{-x^3 If 3<_x<_8
{3x^2+1 If x>8
The lines go under the inequality lol but please help !

Answers

Answers:f(-5) = 23f(12) = 433

==================================================

Explanation:

The given piecewise function is

[tex]f(x) = \begin{cases}-4x+3 \ \text{ if } \ x < 3\\-x^3 \ \text{ if } \ 3 \le x \le 8\\3x^2+1 \ \text{ if } \ x > 8\end{cases}[/tex]

At first piecewise functions may be strange confusing things, but they aren't so bad. I like to think of it like this: f(x) is a function that changes its identity based on what the input x is. We have three situations

f(x) = -4x+3 when x < 3f(x) = -x^3 when [tex]3 \le x \le 8[/tex]f(x) = 3x^2+1 when x > 8

In a sense, we have three different functions but they are combined somehow.

If x is smaller than 3, then we go for the first definition. Or if x is between 3 and 8, then we go for the second definition. Or if x is larger than 8, then we go for the third definition.

-----------------------

f(-5) means f(x) when x = -5. We see that -5 is smaller than 3, so x = -5 makes x < 3 true. We'll use the first definition

f(x) = -4x+3

f(-5) = -4(-5)+3

f(-5) = 20+3

f(-5) = 23

------------------------

Now the input is x = 12. This is larger than 8. In other words, x = 12 makes x > 8 true. We'll use the third definition

f(x) = 3x^2+1

f(12) = 3(12)^2+1

f(12) = 3(144)+1

f(12) = 432+1

f(12) = 433

------------------------

Side notes:

We won't use the second definition since we don't have any x inputs between 3 and 8To say "less than or equal to" on a keyboard, you can write "<=" without quotes. For example, [tex]x \le 5[/tex] is the same as x<=5

Identify the terms, variables, coefficients and constants in each expression -4a-7b+5+c & 7-5h-2-k & 5-4x-8y & 9k+7-k+4 & -5a-7+5d+h & 7m-5-n-8k
Thank you!

Answers

Problem 1

Answers:Terms = -4a, -7b, 5, cVariables = a, b, cCoefficients = -4, -7, 1Constants = 5

---------------------

Explanation:

Each term is separated by a plus sign. If we had something like -4a-7b, then rewrite it as -4a+(-7b). This works because subtraction is really adding a negative. Example: 2-3 = 2+(-3)

So the original expression becomes -4a+(-7b)+5+c and we see there are four terms here.

The terms with the variables are -4a, -7b and c. The variables are simply letters so we just say a,b,c are the variables. The coefficients are the numbers to the left of the variables. For the term c, it is really 1c, so the coefficient is 1.

The constant is the term without a variable multiplied with it. So that would be the 5. As the name suggest, the constant term does not change based on whatever the variables are.

=========================================================

Problem 2

Answers:terms = 7, -5h, -2, -kvariables = h,kcoefficients = -5, -1constants = 7, -2

--------------------------------------

Explanation:

We'll follow the same idea as problem 1.

Rewrite 7-5h-2-k as 7+(-5h)+(-2)+(-k) and we see there are four terms.

The term -k is the same as -1k, so the coefficient is -1

The variables this time are h,k as those are the two letters that show up.

The constants are 7 and -2 because no variables are attached to them.

Use a calculator to evaluate Saira's expression to find her approximation for the value of LaTeX: \pi\:πto the nearest thousandth.

Given:

Area of a circle, A=50.265 sq. units.

Radius of circle, r = 4 units.

To find:

The value of π to the nearest thousandth.

Solution:

Formula for area of a circle is

[tex]A=\pi r^2[/tex]

[tex]\dfrac{A}{r^2}=\pi [/tex]

[tex]Ar^{-2}=\pi [/tex]

Now, using [tex]Ar^{-2}[/tex] expression, we can find the value of π.

[tex]\pi=50.265904(4)^{-2}[/tex]

[tex]\pi=\dfrac{50.265904}{4^2}[/tex]

[tex]\pi=\dfrac{50.265904}{16}[/tex]

[tex]\pi=3.141619[/tex]

Approximate the value to the nearest thousandth (three digits after decimal).

[tex]\pi\approx 3.142[/tex]

Therefore, the approximated value of π is 3.142.

A business just took out a loan for $100,000 at 10% interest. If the business pays the loan off in three months, how much did the business pay in interest?

Answers

Answer:

$2,500

Step-by-step explanation:

The amount the business pay in interest can be calculated using the sinple interest formula as shown:

Simple Interest = Principal × Rate × Time/100

Given Principal = $100,000 (Loan)

Rate = 10%

Time (in years) = 3months = 3/12 years

Substituting the parameters into the formula we will have;

SI = 100,000×10×3/12×100

SI = 1000×30/12

SI = 30,000/12

SI = $2,500

Therefore the business pays an interest of $2,500

Suppose Clare labels the books at a constant speed of s books per minute. Write an equation that represents the relationship between her labeling speed and the number of minutes it would take her to finish labeling.

Answers

Answer:

75 minutes

50 minutes

Number of minutes to finish labelling = Total number of books labelled / Time taken to label them (speed of labelling)

Step-by-step explanation:

Complete question below:

Clare volunteers at a local library during the summer. Her work includes putting labels on 750 books.

How many minutes will she need to finish labeling all books if If she takes no breaks and labels:

a. 10 books a minute

b. 15 books a minute

Suppose Clare labels the books at a constant speed of books per minute. Write an equation that represents the relationship between her labeling speed and the number of minutes it would take her to finish labeling

Solution

a. 10 books a minute

Number of minutes to finish labelling all books at 10 books per minute = Total books / books labelled per minute

= 750 / 10

= 75 minutes

Number of minutes to finish labelling all books at 10 books per minute = 75 minutes

b. 15 books a minute

Number of minutes to finish labelling all books at 15 books per minute = Total books / books labelled per minute

= 750 / 15

= 50 minutes

Number of minutes to finish labelling all books at 15 books per minute = 50 minutes

c. The relationship between her labeling speed and the number of minutes is Total number of books labeled ÷ Time taken to label them

Number of minutes to finish labelling = Total number of books labelled / Time taken to label them (speed of labelling)
