The cost of a phone is reduced by 20%. The new cost is $70.40 . What was the original price?1. $88.002.$84.003.$58.404.$56.00

First divide 26.33 with 8 to find the cost per gallon

26.33/8 = ~3.29 (rounded).

Each gallon of gas costs $3.29

Next, multiply the cost per gallon with the amount of gallons, 20 in this case.

20 x 3.29 = 65.80

$65.80 is your answer

Answer:

Option C

{-1,3,5}

Step-by-step explanation:

A mapping is a subset of ordered pair (x,y) where x belongs to first set and y belongs to second set.

Hence a mapping is a subset of cartesian product AXB.

Here A = {-2,1,3,5} and

B = {2,4,6,8}

Ordered pair given by the mapping is

(-2,1) (3,6) and (5,8)

In other words, -2 is mapped on to 1, 3 to 6 and 5 to 8

Domain = set of elements in the I set which are mapped

= {-1,3,5}

So, to set up your equation is the hardest part. If you remember the basic format, you're set.

I(t) = P * (1+r%)^t

t= time and this will be our variable

Initial amount P = $2740

Rate = 4.3% which converts numerically into .043

I(t) = 7000

Before we get to find out how to find how many years it takes to get to $7000, set up the basic equation by plugging in what we know.

I(t) = $2740(1+4.3%)^t

I(t)=2740(1.043)^t

Now plug in for $7000 for I(t)

7000=2740(1.043)^t                 Divide both sides by 2740

7000/2740 = 2740/2740(1.043)^t

2.55474453=(1.043)^t

Now you can solve for t in two ways. You can either use the natural log or graph it on your graphing calculate and see when the two equations meet.

In your calculator you can set up:

ln(2.55474453)/ln(1.043) = t                 which is the method I prefer since it's much simpler

t=22.278528

but you can also graph it in your ti-84

with

y1=2.55474453

y2=(1.043)^x

and find where they intersect on the graph.

either way it'll be the same answer

Alright, so first we need to establish two things.

First, the compliment of a set is like the extreme opposite; everything that is not in set B will be in the complement.

Second, we need to find out what B is.

Okay, so B is everything that is greater than 2, that's given. That includes 3, 4, and 5. B = {3, 4, 5}. There are three items in this set.

The numbers that aren't included are 1 and 2. The complement of B, let's call this C I guess, is C = {1, 2}. There are 2 items in this set.

The answer, I believe, is two. Hope this helps!

28/7=4km is car journey covered by car in 1l

64/4=16l

The car would use 16 liters of petrol to cover 64 km.

To find out how many liters of petrol the car uses to cover 64 km, we can set up a proportion using the given information. Since the car uses 7 liters of petrol to cover 28 km, we can say that the fuel consumption rate is 7 liters per 28 km. To find out the fuel consumption rate for 64 km, we can set up the proportion:

7 liters / 28 km = x liters / 64 km

Cross-multiplying, we get 28x = 7 * 64.

Dividing both sides by 28, we get x = 7 * 64 / 28 = 16 liters. Therefore, the car would use 16 liters of petrol to cover 64 km.

The range is the difference between the highest number and the lowest number.

The lowest number is 5, the highest number is 13.

The range is 13 - 5 = 8 runs.

The correct answer for the range is: "5 to 13 runs" with a median of 8  and here is why:

The range of a set of numbers is what values could have or could be based on the lowest and highest values. The range is not the same as the average or the median. 5 runs was the least amount of runs that happened during one game and 13 was the most in another.

The average is calculated by adding all of the numbers added together and then divides by how many numbers that you added together.

The median is found by removing the lowest number and then the highest number. You repeat this process until you are left with only one number.

There are other things to find as well, but I think you understand now

Range: 5-13 ; 8

Average: 9

Median: 8

Answer:

9, 7,-8.3,>

Step-by-step explanation:

5)-3 is marked exactly 3 units to the left of origin 0.

(since negative sign we mark on left of 0)

6) |-9| = absolute value of 9 = 9

7) y-11=-4

Add 11 to both the sides

WE get y =7 is the solution

8) a + b when a = 2.5 and b = -10.8.

= 2.5+(-10.8) = -(10.8-2.5) = -8.3

9) 0.4 is positive hence lies to the right of origin.

B: Concepts with monetary value

Step-by-step explanation:

for future reference the exact meaning of intellectual property law is the rules for securing and enforcing legal rights to inventions, designs, and artistic works. it is obviously easy to draw the connections from the meaning to the answer B.

Intellectual property law protects intangible creations with monetary value, fitting best with answer B: Concepts with monetary value. It includes patents, trademarks, copyrights, and trade secret law, and is essential for creators and inventors to capitalize on their work.

Intellectual property law deals with the protection of intangible creations that have monetary value, such as art, written work, research findings, and ideas.

The correct answer to the question provided is B: Concepts with monetary value.

Intellectual property includes patents, trademarks, copyrights, and trade secret law which allow inventors and creators to produce, publish, and sell their work and inventions while preventing others from using them without authorization or compensation.

Countries across the globe have distinct laws protecting intellectual property, and organizations like the World Intellectual Property Organization (WIPO) strive to harmonize these laws internationally. Intellectual property is nonexcludable and non rivalrous in nature, often leading to positive externalities and offering private benefits to creators and inventors.

The slope intercept from of equation is y= -7x + 41.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

A line that passes through points (7, −8). and parallel to y = −7x − 8

Now, the slope of given  parallel line is -7 and slope of line which is to parallel also of have the same slope.

So, slope of parallel line = -7

Now, using slope intercept form

y -a = m( x- b)

y - (-8)= (-7)(x-7)

y +8 = -7x + 49

y= -7x + 71

Hence, the slope intercept from of equation is y= -7x + 41

Answer:

The exponent -9  makes the given statement true.

Step-by-step explanation:

We have been given an incomplete mathematical statement and we need to figure out the exponent for 5 on the right hand side to complete the statement.

The given incomplete statement is [tex]\frac{1}{5^{9}}=5^{?}[/tex].

Let us rewrite the left hand side of the expression by moving the exponential term to the numerator using exponent property. As per this property, if we shift an exponential term from denominator to numerator (or vice versa), the sign of exponent changes.

Therefore, we get:

[tex]5^{-9}=5^{?}[/tex]

Now that we have common bases on both the sides, we can equate the exponents. And upon equating the exponents, we can see that the 'question mark' should be replaced by -9 in order for statement to be true.

Therefore, exponent -9 on the right hand side will make the statement true.

Answer:

1/5^9 = 5^-9

Step-by-step explanation:

20,

So, there are 6 total parts,

X = 60/6

Each X = 10

So, 10*2 = 20

20 of them are golden.

To determine the number of golden nail paints, the total nail paints (60) are divided by the sum of the ratio parts (3), resulting in 20 nail paints per part. Multiplying the part for golden paints (1) by 20 gives us 20 golden nail paints.

The ratio of silver nail paints to golden paints is given as 4 to 2, which simplifies to a ratio of 2 to 1. This means that for every 2 silver nail paints, there is 1 golden nail paint. If there are a total of 60 nail paints, we need to determine how many of them are golden. To find out, we divide the total number of nail paints by the sum of the ratio parts (2 + 1 = 3 parts). Hence, each part represents 20 nail paints (60 ÷ 3).

To calculate the number of golden nail paints, we then multiply the number of parts for golden paints (which is 1 part) by the nail paints per part, so we get 20 x 1 = 20 golden nail paints.

All the sides of a square are equal.

Perimeter of a square = 4(measure of 1 side)

Therefore if a square contains 4 sides, and the measure of one side is 2 inches, the perimeter is 8 inches. (2x4)

The definition of directly proportional is when one substance increases at the same rate of another substance. When a number is plugged into our formula, the perimeter increases.
