The 7th grade basketball team won 9 out of 15 games. What is the ratio of losses to wins?
Answer:
The ratio of losses to wins is 6:9 or if simplified 3:2
Step-by-step explanation:
The 7th grade basketball team played 15 games in total. If they had 9 out of those 15 games they lost the other 6. So, the ratio of losses to wins is 6:9. Losses goes first because its first in the word problem. To simplify a ratio find the number they both divide into. In this case its 3. 6 divided by 3 is 2. And 9 divided by 3 is 3. So in simplest form the answer is 3:2 :)

Which equations have a greater unit rate than the rate represented in the table? x y 3 2 6 4 9 6
Answer:
Any equation with a slope greater than ²/₃
Step-by-step explanation:
Given table:
\(\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} 3 & 2 \\\cline{1-2} 6 & 4 \\\cline{1-2} 9 & 6 \\\cline{1-2} \end{array}\)
The unit rate is a ratio that compares the first quantity to one unit of the second quantity. The unit rate is also the slope of a linear equation.
Linear equation
\(y = mx + b\)
where:
m is the slopeb is the y-interceptTo find the slope, take two ordered pairs from the table:
\(\sf let \: (x_1,y_1)=(3,2)\)
\(\sf let \: (x_2,y_2)=(6,4)\)
Substitute them into the slope equation:
\(\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-2}{6-3}=\dfrac{2}{3}\)
Therefore, the unit rate is ²/₃.
Any equation with a slope greater than ²/₃ is an equation with a greater unit rate than that represented in the given table.
Slope of table

m=4-2/6-3m=2/3Any equation having slope greater than 2/3 has higher unit rate than that of table
At 2 hours before sunset, the temperature is 0°F. At 2 hours after sunset, the temperature is −4°F. Identify the equation representing the temperature y, in degrees Fahrenheit, at x hours after sunset.
y = ___ x + ___
Answer:
The answer is y = -4x + 0
Step-by-step explanation:
Because the temperature is -4 and when since zero is your starting point you do gown four which is why its negative and since zero is the start it would be the answer for y
For the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -4x + 0.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

A Ferris wheel accommodate 75 people in 30 minutes . how many people could ride the Ferris wheel in 6 hours? what was the rate per hour?
Answer: The ferris wheel could accomodate 900 people in 6 hours. The rate per hour was 150 people.
Step-by-step explanation:
To start off we can find the number of people by deciding how many time slots of 30 minutes are in 6 hours. Since 30 minutes is half an hour we just do 2 times 6 which would give us 12. Since 75 people can fit in 30 minutes then we do 12 times 75 for the whole 6 hours which comes out to 900.
Once we have the number of people in 6 hours then we can find the hourly rate. To do this we just take the number of people (900) in the whole time (6 hours) and divide 6 from 900 which would give us the hourly rate of 150.
Answer:
900 people
Step-by-step explanation:
One hour is 60 minutes, and the number of thirty minutes in an hour is two. To get the number of thirty minutes in 6 hours, you would do 2 x 6, which is 12. After this, you would do 12 x 75 since 75 people ride it in 30 minutes. This equals 900.

PLEASE ASAP Find the value of x
Answer: this is in a fraction: X = 16/5, decimal form: x = 3.2, and in a mix number: x = 3 1/5
Step-by-step explanation:
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

The dot plots below show the runs scored in each of the first games of the season by the Hawks and the Eagles. Runs Scored (Ha Runs Scored Part A What is the mean number of runs for the Hawks? Answer _ Part B Add two points to the dot plot for the Hawks that show possible runs scored in the next two games if the mean number of runs decreases and the range increases. Part CAdd two points to the dot plot for the Eagles that show possible runs scored in the next two games if the mean number of runs stays the same.
Answer:
Part B: 8 and 2 (more answers ofc)
Part C: Two more dots on 6 (more than one answer tho)
Step-by-step explanation:
Part B:
The added number of dots is 39 at the beginning and the mean is 3.9. (39/10). Since we have to add 2 dots the equation will be (39 + ? + ?) / 12 = Less than 3.9. We also need the range to increase. This means that one of the blanks must be larger than 7 (the largest dot on the dot plot!) I just went with 8 to keep the mean as small as possible. This leaves 1 more blank to figure out. There are multiple answers to this problem but I went with 2 just because then the mean would be 3.5 a better answer than something like 3.58333333333.
Part C:
If you think about it all the dots added up should be 6x12 = 72. Currently all the dots add up to 60. 72-60 is 12. This means that 12 is equal to 2 dots. I guess you could also do 5 and 7, 8 and 4, etc.

what are the properties of rational exponents and how are they used tk solve problems
What makes a NUMBER rational is the ability to have a perfect square root, cube root, or have these components: Perfect square/cube, whole number, repeating (pattern) decimal, termination decimal, and I think one more that I can't remember.
The properties of the rational exponents are given and a rational equation is of the form b = aˣ
What are the laws of exponents?
When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the rational exponent equation be A
Now , the properties of the exponent equations are
mᵃ×mᵇ = mᵃ⁺ᵇ
The powers of the exponents are added together
mᵃ / mᵇ = mᵃ⁻ᵇ
The powers of the exponents are subtracted together
( mᵃ )ᵇ = mᵃᵇ
The powers of the exponents are multiplied together
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
Any number raised to the power of 0 is 1
m⁻ᵃ = ( 1 / mᵃ )
Hence , the exponents are solved

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

you want to buy some beans . a 6 - ounce package costs $2.16 . a 15 - ounce package costs $5.55 . a 26 - ounce package costs $9.10 . which package is the best buy
Answer:
26-ounce package
Step-by-step explanation:
Divide the cost for a 6-ounce and a 15-ounce package separately by the number of ounces listed above. 1 ounce for a 6-ounce package costs around $0.36 and 1 ounce for a 15-ounce package cost around $0.37. If we put the 26-ounce package in place, then each ounce cost $0.35. We want to buy the one that is the cheapest out of all of them and since the 26-ounce package cost more cheaper than the other packages, then you should buy the 26-ounce package since it is the best deal.
