Step-by-step explanation:

We have, 25% × x = 21
or,

25
--------   × x = 21
100  

Multiplying both sides by 100 and dividing both sides by 25,

we have x = 21 ×

100

25

x = 84

If you are using a calculator, simply enter 21×100÷25, which will give you the answer.

for each of the number lines, write an absolute value equation in the form |x-c|=d, where c and d are some numbers, to satisfy the given solution set.

Answers

An absolute value that can represent the solution set is: |x - 2|=4

From the number line, we have the domain of the x values to be:

x = -4 to 6

This means that the least x value is -4, and the largest is 6

The absolute value equation is given as:

|x - c|=d

Assume that d = 4.

So, we have:

|x - c|=4

Assume that c is 2.

So, we have:

|x - 2|=4

When solved, we have:

x = -2 or x = 6

-2 and 6 are within the domain of the number line.

Hence, an absolute value that can represent the solution set is: |x - 2|=4

1. Carbon-14 has a half-life of 5,700 years. Scientists use this fact to determine the age of things made of organic material. Suppose the average page of a book containing approximately 0.5 mg of carbon-14 is put into a time capsule. How much carbon-14 will each page contain after each of the following numbers of years?


a. How many half-years is each quantity of years?


b. How much carbon-14 remains after the number of years shown to the left?

c. Challenge: see if you can create a table that uses 5700 as part of the exponent, and the actual number of years given above. Challenge function:

Answers

Answer: Since 5700 years is the "half-life" exactly 0.25 mg will remain.

Step-by-step explanation: Well, we know that half of it will change into another form in 5700 years, so if you start with .5 mg than in 5,700 years you would have half or .25 mg. 11,400 is another half life so half of .25 = .125 mg. 22,800 is two more half lives so half .125 twice.

Answer:

-66/15

Step-by-step explanation:

Convert all of them to improper fractions:

26/3 - 19/5 + 139/15

Using the rule of BODMAS;

We will add first before we subtract.

26/3 - (19/5 + 139/15)

L.C.M of 5 and 15 is 15

26/3 - (13×19)+(1×139)/15

{26/3 - 196/15}

Now we will subtract

LCM of 3 and 5 is 15

(5×26) - (1×96)/15

=130 - 96/15 = -66/15.

A merchant offers a large group of items at 32% off. Later, the merchant takes 16% off these sale prices and claims that the final price of these items is 186 off the original price. What is the total percent discount?

Answers

Answer:

 56 % of original price or 44 % off

Step-by-step explanation:

x times 0.7 times 0.8 = .56x    

The total percent discount is 42.88%.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."

Let's assume that the original price of an item is 100 dollars.

After the first discount of 32%, the price of the item becomes:

100 - (32% of 100) = 68 dollars

After the second discount of 16%, the price of the item becomes:

68 - (16% of 68) = 57.12 dollars

So the final discount on the original price is:

100 - 57.12 = 42.88 dollars

To find the total percent discount, we need to calculate what percentage 42.88 dollars is of the original price of 100 dollars:

(42.88 / 100) x 100% = 42.88%

Therefore, the total discount is 42.88%.

p*15%

p*15%*6%

Step-by-step explanation:

Answer:

Part A: 0.85p

Part B: 0.901p

Step-by-step explanation:

The phone's original price: 100%

The phone's sale price: 15% off the original price

p = original price of the phone

Part A:

100% - 15% = 85%

85% = 0.85

The expression: 0.85p

Part B:

6% = 0.06

0.06 * 0.85p ==> (the sales tax * the discounted price of the phone)

0.051p

0.85p + 0.051p

0.901p

Number 1:An object on earth has a mass of 34 g and an acceleration of 9.8 m/s2. What is its weight (force)?
Number 2:f the mass of an object is 57gm and the volume is 3cm cubed. What is the density of the object? (do not include units in your answer)

Answers

Answer:you gotta divide

Step-by-step explanation:

Answer:

1. 333.2 N

2. 19

Step-by-step explanation:

1. So first lets write what we have :

Mass= 34g

Acceleration=9.8m/s^2

Force= x

Formula: Force= Mass * Acceleration

Force= 34 * 9.8

Force = 333.2N

So the force is equal to mass * acceleration

The answer then becomes 333.2N

2. Mass = 57gm

Volume= 3cm^3

Density= x

Density = mass / volume

The density is equal to the mass divided by the vilume thus 57 / 3 = 19

Density = 19
