The phone case you want to buy is marked down 30%, and you have a 25% off coupon. You pay $42.00. Can this equation be used to find the original price of the phone case? If so, what is the original price of the item? Explain. (5 points) 3/4(0.7c) = 42
Yes, the equation provided can be used to calculate the original price of the phone case. After solving the equation, we found out that the original price of the phone case was approximately $80.
Explanation:Yes, the equation you provided, 3/4(0.7c) = 42, can certainly be used to find the original price of the phone case (c). The equation is obtained by recognizing that you're receiving two discounts: a 30% or 0.3 discount off the original price (leaving 70% or 0.7 of the original price) and then a 25% or 0.25 discount (meaning you're paying 75% or 0.75 of the price after the first discount).
To find the original price, you want to solve this equation for 'c'. That would involve dividing both sides by 3/4(0.7) equaling to 0.525. So, it will look like: 42 ÷ 0.525 = c. Doing the calculation, c equals approximately $80.
Therefore, the original price of the phone case was $80.

Which expression is equivalent to 32?
Final answer:
The expression equivalent to 32 might refer to a mathematical manipulation or a unit conversion. In equations, 32 is what remains when you subtract 32 from one side of an equation like x + 32 = 64. Meanwhile, in conversions, multiplying the number of quarts by 32 gives you the equivalent volume in fluid ounces.
Explanation:
The expression is equivalent to 32 and could be interpreted in different contexts. Using mathematical manipulation, when you subtract 32 from both sides of an equation, the equality holds. For example, if you have an equation like x + 32 = 64, subtracting 32 from both sides gives us x = 64 - 32, which simplifies to x = 32. This demonstrates an application of the principle that you can add or subtract the same number from both sides of an equation without changing its solution.
In relation to conversion between different units of measurement, specifically volume, when you convert quarts to fluid ounces, the conversion factor is 32 because there are 32 fluid ounces in one quart. Consequently, to find how many fluid ounces are in a given number of quarts, you multiply the number of quarts by 32. For example, 4 quarts equal 4 × 32, which is 128 fluid ounces.
Furthermore, when dealing with electrical resistance, 'equivalent resistance' is another situation where the number 32 might be relevant. Depending on the context and the specific details of an electrical circuit, one of the listed equivalent resistances may be the correct answer to a problem involving calculating the total resistance.
Two points are located at (−9,−8) and (−6,−4) . Complete the equations below to show how you can use the Pythagorean theorem to find the distance between these two points.
The distance between two points in a coordinate plane can be found using the Pythagorean theorem. For the points (-9,-8) and (-6,-4), the distance is 5 units.
Explanation:The Pythagorean theorem can be used to find the distance between two points in a coordinate plane. To find the distance between the points (-9,-8) and (-6,-4), we can consider the horizontal and vertical differences as the legs of a right triangle. The horizontal difference is 3 and the vertical difference is 4.
Using the Pythagorean theorem, we have:
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
c = sqrt(25) = 5
Therefore, the distance between the two points is 5 units.

Step-by-step explanation:
go it right on edge
A polynomial function with rational real coefficients, a leading coefficient of 3, and roots of square root of 5 and 2 can be represented as f(x) = 3(x - 2)(x - √5).
Explanation:A polynomial function with rational real coefficients, a leading coefficient of 3, and roots of square root of 5 and 2 can be represented as:
f(x) = 3(x - 2)(x - √5)
To find the polynomial function, we use the fact that the roots of a polynomial are the values of x for which the polynomial is equal to zero. Since the leading coefficient is 3, we multiply the expression (x - 2)(x - √5) by 3 to obtain the polynomial function.
In this case, the polynomial function of lowest degree is a quadratic function.

An Investor invested a total of $2,600 in two mutual funds. One fund earned 7% profit while the other earned 3% profit. If the investor’s total profit was $150, how much was invested in each mutual fund?
let x = amount invested at 3%
so, (2600 - x) is invested at 7%
.07 *(2600 - x) + .03 *(x) = 138
182 - .07x + .03x = 138
-.07x + .03x = 138 - 182
-.04x = -44
-.04x / -.04 = -44 / -.04
x = 1,100
so amount invested at 7% is (2600 - 1100) or 1500
consequently amount invested at 3% is 1100
$1,100 invested at 3%
$1,500 invested at 7%
The money invested in both of the funds are $800 and $1800 respectively.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
Suppose the money invested in one of the funds be x.
Then, in the other fund the investment is (2600 - x).
Now, the equation for the total profit from both investments can be obtained as,
7% × x + 3% × (2600 - x) = 150
⇒ 7/100 × x + 3/100 × (2600 - x) = 150
⇒ 4x/100 = 150 - 78
⇒ x = 1800
Thus, the investment in the other fund is 2600 - 800 = $800.
Hence, the investment for both the funds are $800 and $1800 respectively.

the number of songs purchased from an online music store on the first day the store open was 300,000. The number of songs purchased on day x after the first day is given by the expression 300,000 (1.008^n). each day the number of songs purchased is what percent greater than the number of songs purchased the preceding day?
Answer:
The percentage is 0.008%
Step-by-step explanation:
The number of songs purchased each day from an online music store is 0.8% greater than the number purchased the previous day.
The original number of songs purchased from the online music store on the first day was 300,000. The number of songs purchased on any given day x is represented by the expression 300,000 ([tex]1.008^n[/tex]), where n is the number of days after the first day. To find the percent increase each day, you examine the multiplicative factor 1.008. This reflects a 0.8% (or 0.008 in decimal form) increase in the number of songs purchased from one day to the next. Therefore, each day the number of songs purchased is 0.8% greater than the previous day.

Your friend finds 192 divided by 6 by writing (6 x 30) + (6 x 2). She says the answer is 12. Is your friend correct? EXPLAIN!
No, your friend is not correct. The answer to 192 divided by 6 is 32, not 12.
Explanation:No, your friend is not correct. When dividing 192 by 6, we need to find how many times 6 can go into 192. One way to do this is by subtracting multiples of 6 from 192 until we reach 0. This method is called long division. Let's work through it step by step:
Write 192, the dividend, inside the division symbol.Write 6, the divisor, outside the division symbol.Divide 6 into the first digit of 192, which is 1. The answer is 0, as 6 cannot go into 1.Bring down the next digit, which is 9.Divide 6 into 19, which gives us 3. Write the 3 above the line, in the quotient, as our first digit.Multiply 6 by 3, which gives us 18. Subtract 18 from 19, which leaves us with 1.Bring down the next digit, which is 2.Divide 6 into 12, which gives us 2. Write the 2 above the line, in the quotient, as our next digit.Multiply 6 by 2, which gives us 12. Subtract 12 from 12, which leaves us with 0.So the answer to 192 divided by 6 is 32. Your friend's method of using (6 x 30) + (6 x 2) is incorrect because it does not result in the correct quotient.
