-5/7 is greater than -4/5
Answer:
Yes.
Step-by-step explanation:
Forget about the negative sign for now.
Just compare 5/7 and 4/5 first.
Find the common denominator so it's easy to determine which one is bigger/larger.
5/7=25/35 and 4/5=28/35
From here, you can tell which one is bigger/larger, right?
Definitely, 25/35<28/35.
5/7<4/5, but don't forget the negative sign.
It's -5/7 compared to -4/5, so the answer is yes, -5/7>-4/5.

HOW TO: SOLVE AN APPLICATION
Step 1. Identify what you are asked to find and choose a variable to represent it.
Step 2. Write a sentence that gives the information to find it.
Step 3. Translate the sentence into an equation.
Step 4. Solve the equation using good algebra techniques.
Step 5. Check the answer in the problem and make sure it makes sense.
Step 6. Write a complete sentence that answers the question.
Remember that whatever the application, once we write the sentence with the given information (Step 2), we can translate it to a percent equation and then solve it.
Do you pay a tax when you shop in your city or state? In many parts of the United States, sales tax is added to the purchase price of an item. See Figure 6.7. The sales tax is determined by computing a percent of the purchase price.
To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.
Corbin’s parents want to save $50,000 for his college education and already have $25,000. About how long would it take them to double their current savings if they can earn an 8% interest rate?
Answer:
about 9 years
Explanation:
To solve this problem we will use what is known as 'The Rule Of 72.' This particular rule is what the Mathematical World considers a 'short cut.' That's because it is an efficient way to calculate how long it takes money to double, base solely on the interest rate. However, it is important to remember that this rule only provides an estimate, and not an exact amount of years.
The Rule Of 72 is as follows:
[tex]\displaystyle\frac{72}{[interest][rate]}[/tex] = time it takes for investment to double
*please note that I separated the word 'interest' and 'rate' using brackets. however, please ignore them. as I only used the brackets to separate the words since the equation option does not allow space between letters.
Now that you understand the Rule Of 72, let's use it to solve the given problem.
Corbin’s parents want to save $50,000 for his college education and already have $25,000. About how long would it take them to double their current savings if they can earn an 8% interest rate?
Although the first sentence in the problem gives us information of the parents goal and their current amount saved, this information will not be useful to us. As the Rule Of 72 goes, we only need to know the interest rate to solve.
Looking at the second sentence it states the interest rate is: 8%
Now substitute the interest rate in the Rule Of 72.
[tex]\displaystyle\frac{72}{[interest][rate]}[/tex] ⟶ [tex]\displaystyle\frac{72}{8}[/tex]
The last step is to simplify (or divide).
[tex]\displaystyle\frac{72}{8} = 9[/tex]
So, according the Rule Of 72, it will only take about 9 years to double their current savings.
Answer:
9 years

Which of the following represents the equation of the inverse of y=5x-20
The equation of the inverse of y = 5x - 20 is y = (x + 20)/5.
Explanation:To find the equation of the inverse of y = 5x - 20, we need to switch the x and y variables and solve for y. So the inverse equation will be x = 5y - 20. Now, let's isolate y by adding 20 to both sides: x + 20 = 5y. Next, divide both sides by 5: (x + 20)/5 = y. Therefore, the equation of the inverse is y = (x + 20)/5.
What is the area of a circle with a diameter of 4x - 24? Specifically what steps would you take?
Answer:
12.56x^2+452.16
Step-by-step explanation:
A=pie r^2
(4x-24)/2= 2x-12 which is your radius
(2x-12)^2=4x^2+144
Pie=3.14ish
3.14(4x^2+144)
12.56x^2+452.16
Answer:
Step-by-step explanation:
The formula for the area of a circle is
A = πr². We need the radius, r, to calculate the circle.
If the diameter of the circle is 4x - 24, then the radius is half that, or
2x - 12.
Then the area of the circle in question is A = πr², or
A = π(2x -12)²
If desired, this could be expanded:
A = π(4)(x - 6)² = 4π(x^2 -12x + 36)
The population of Australia is approximately 19,500,000. Approximately 195,000 are of the ethnic group called
Aborigines. The Aborigines population is about what percent of the total population?
Answer:
1% of the whole australian population is Aborigines.
Step-by-step explanation:
Do [tex]\frac{part}{whole}[/tex] which is [tex]\frac{195000}{19500000}[/tex] and you get the answer 0.01 which (as a percent) can also be recognized as 1%.
Final answer:
The Aboriginal population forms about 1% of the total population of Australia when using the provided figures of a total population of 19,500,000 and an Aboriginal population of 195,000.
Explanation:
To calculate the percentage of the Aboriginal population in Australia relative to the total population, we can use the following formula:
Percentage = (Part / Whole) × 100
Here the 'Part' is the Aboriginal population and the 'Whole' is the total population of Australia. Plugging in the values provided:
Total Population (Whole) = 19,500,000Aboriginal Population (Part) = 195,000Percentage of Aboriginal population = (195,000 / 19,500,000) × 100
Perform the division:
Percentage = 0.01 × 100
Finally, we multiply by 100 to convert the decimal to a percentage:
Percentage = 1%
Therefore, the Aboriginal population forms about 1% of the total population of Australia. Note that this number might be an underrepresentation since recent estimates indicate that the Aboriginal population is about 450,000, which would be a larger percentage.

Suppose x is an odd number. Write an expression to represent each of the following:
a. The odd number immediately following x. _________
b. The odd number immediately preceding x. _________
Thank You!! =^)
Answer:
a. The odd number immediately following x = ( x+ 2)
b. The odd number immediately preceding x = ( x- 2)
Step-by-step explanation:
Odd Numbers : The number which DO NOT have 2 as their common factor are called odd numbers.
Hence, odd number IS NOT divisible by 2.
Some examples are : 1,3,5,7,9,..........
So, by the given examples, we can see that the difference between any TWO consecutive odd number is ALWAYS 2.
Here, given x : odd number
So, using the above argument :
a. The odd number immediately following x = ( x+ 2)
b. The odd number immediately preceding x = ( x- 2)
Final answer:
a. The expression for the odd number immediately following an odd number x is x + 2.
b. The odd number immediately preceding x is x - 2.
Explanation:
a. If x is an odd number, the next consecutive number is an even number, which is obtained by adding 1 to x. Since odd numbers are two units apart, adding 2 to an odd number x would result in the next odd number. Therefore, the expression to represent the odd number immediately following x would be x + 2.
b. Similarly, the odd number immediately preceding an odd number x can be found by subtracting 2, because the prior odd number is two units less than x. The expression for the odd number immediately preceding x is x - 2.

There are two numbers whose sum is 64. The larger number subtracted from 4 times the smaller number gives 31. Find the numbers.
There are two numbers whose sum is 64. The larger number subtracted from 4 times the smaller number gives 31. Then the numbers are 45 and 19
Solution:Given that, There are two numbers whose sum is 64.
Let the number be a and b in which a is bigger.
Then, a + b = 64 ------ eqn (1)
The larger number subtracted from 4 times the smaller number gives 31.
4 x b – a = 31
4b – a = 31 ----- eqn (2)
We have to find the numbers.
So, from eqn (2)
a = 4b – 31
Subatitute a in (1)
4b – 31 + b = 64
On solving we get
5b = 64 + 31
5b = 95
b = 19
So, b = 19, then eqn 1
a + 19 = 64
On simplification,
a = 64 – 19
a = 45
Hence, the two numbers are 45 and 19

Option A. x 7 8 9 10 y -49 -56 -63 -70 is the right answer.
Step-by-step explanation:
The inverse of a function means that the input becomes the output of the function and the output becomes input. When the function is given in the form of ordered pairs, the fiirst element of each ordered pair represents input and second element represents the output.
So, for given function: {(-49,7), (-56,8), (-63,9), (-70,10)}
The inverse will be:
{(7, -49), (8,-56), (9,-63), (10, -70)}
Hence,
Option A. x 7 8 9 10 y -49 -56 -63 -70 is the right answer.
